81 Edison, Thomas Alva
SUBJECT AREA: Architecture and building, Automotive engineering, Electricity, Electronics and information technology, Metallurgy, Photography, film and optics, Public utilities, Recording, Telecommunications[br]b. 11 February 1847 Milan, Ohio, USAd. 18 October 1931 Glenmont[br]American inventor and pioneer electrical developer.[br]He was the son of Samuel Edison, who was in the timber business. His schooling was delayed due to scarlet fever until 1855, when he was 8½ years old, but he was an avid reader. By the age of 14 he had a job as a newsboy on the railway from Port Huron to Detroit, a distance of sixty-three miles (101 km). He worked a fourteen-hour day with a stopover of five hours, which he spent in the Detroit Free Library. He also sold sweets on the train and, later, fruit and vegetables, and was soon making a profit of $20 a week. He then started two stores in Port Huron and used a spare freight car as a laboratory. He added a hand-printing press to produce 400 copies weekly of The Grand Trunk Herald, most of which he compiled and edited himself. He set himself to learn telegraphy from the station agent at Mount Clements, whose son he had saved from being run over by a freight car.At the age of 16 he became a telegraphist at Port Huron. In 1863 he became railway telegraphist at the busy Stratford Junction of the Grand Trunk Railroad, arranging a clock with a notched wheel to give the hourly signal which was to prove that he was awake and at his post! He left hurriedly after failing to hold a train which was nearly involved in a head-on collision. He usually worked the night shift, allowing himself time for experiments during the day. His first invention was an arrangement of two Morse registers so that a high-speed input could be decoded at a slower speed. Moving from place to place he held many positions as a telegraphist. In Boston he invented an automatic vote recorder for Congress and patented it, but the idea was rejected. This was the first of a total of 1180 patents that he was to take out during his lifetime. After six years he resigned from the Western Union Company to devote all his time to invention, his next idea being an improved ticker-tape machine for stockbrokers. He developed a duplex telegraphy system, but this was turned down by the Western Union Company. He then moved to New York.Edison found accommodation in the battery room of Law's Gold Reporting Company, sleeping in the cellar, and there his repair of a broken transmitter marked him as someone of special talents. His superior soon resigned, and he was promoted with a salary of $300 a month. Western Union paid him $40,000 for the sole rights on future improvements on the duplex telegraph, and he moved to Ward Street, Newark, New Jersey, where he employed a gathering of specialist engineers. Within a year, he married one of his employees, Mary Stilwell, when she was only 16: a daughter, Marion, was born in 1872, and two sons, Thomas and William, in 1876 and 1879, respectively.He continued to work on the automatic telegraph, a device to send out messages faster than they could be tapped out by hand: that is, over fifty words per minute or so. An earlier machine by Alexander Bain worked at up to 400 words per minute, but was not good over long distances. Edison agreed to work on improving this feature of Bain's machine for the Automatic Telegraph Company (ATC) for $40,000. He improved it to a working speed of 500 words per minute and ran a test between Washington and New York. Hoping to sell their equipment to the Post Office in Britain, ATC sent Edison to England in 1873 to negotiate. A 500-word message was to be sent from Liverpool to London every half-hour for six hours, followed by tests on 2,200 miles (3,540 km) of cable at Greenwich. Only confused results were obtained due to induction in the cable, which lay coiled in a water tank. Edison returned to New York, where he worked on his quadruplex telegraph system, tests of which proved a success between New York and Albany in December 1874. Unfortunately, simultaneous negotiation with Western Union and ATC resulted in a lawsuit.Alexander Graham Bell was granted a patent for a telephone in March 1876 while Edison was still working on the same idea. His improvements allowed the device to operate over a distance of hundreds of miles instead of only a few miles. Tests were carried out over the 106 miles (170 km) between New York and Philadelphia. Edison applied for a patent on the carbon-button transmitter in April 1877, Western Union agreeing to pay him $6,000 a year for the seventeen-year duration of the patent. In these years he was also working on the development of the electric lamp and on a duplicating machine which would make up to 3,000 copies from a stencil. In 1876–7 he moved from Newark to Menlo Park, twenty-four miles (39 km) from New York on the Pennsylvania Railway, near Elizabeth. He had bought a house there around which he built the premises that would become his "inventions factory". It was there that he began the use of his 200- page pocket notebooks, each of which lasted him about two weeks, so prolific were his ideas. When he died he left 3,400 of them filled with notes and sketches.Late in 1877 he applied for a patent for a phonograph which was granted on 19 February 1878, and by the end of the year he had formed a company to manufacture this totally new product. At the time, Edison saw the device primarily as a business aid rather than for entertainment, rather as a dictating machine. In August 1878 he was granted a British patent. In July 1878 he tried to measure the heat from the solar corona at a solar eclipse viewed from Rawlins, Wyoming, but his "tasimeter" was too sensitive.Probably his greatest achievement was "The Subdivision of the Electric Light" or the "glow bulb". He tried many materials for the filament before settling on carbon. He gave a demonstration of electric light by lighting up Menlo Park and inviting the public. Edison was, of course, faced with the problem of inventing and producing all the ancillaries which go to make up the electrical system of generation and distribution-meters, fuses, insulation, switches, cabling—even generators had to be designed and built; everything was new. He started a number of manufacturing companies to produce the various components needed.In 1881 he built the world's largest generator, which weighed 27 tons, to light 1,200 lamps at the Paris Exhibition. It was later moved to England to be used in the world's first central power station with steam engine drive at Holborn Viaduct, London. In September 1882 he started up his Pearl Street Generating Station in New York, which led to a worldwide increase in the application of electric power, particularly for lighting. At the same time as these developments, he built a 1,300yd (1,190m) electric railway at Menlo Park.On 9 August 1884 his wife died of typhoid. Using his telegraphic skills, he proposed to 19-year-old Mina Miller in Morse code while in the company of others on a train. He married her in February 1885 before buying a new house and estate at West Orange, New Jersey, building a new laboratory not far away in the Orange Valley.Edison used direct current which was limited to around 250 volts. Alternating current was largely developed by George Westinghouse and Nicola Tesla, using transformers to step up the current to a higher voltage for long-distance transmission. The use of AC gradually overtook the Edison DC system.In autumn 1888 he patented a form of cinephotography, the kinetoscope, obtaining film-stock from George Eastman. In 1893 he set up the first film studio, which was pivoted so as to catch the sun, with a hinged roof which could be raised. In 1894 kinetoscope parlours with "peep shows" were starting up in cities all over America. Competition came from the Latham Brothers with a screen-projection machine, which Edison answered with his "Vitascope", shown in New York in 1896. This showed pictures with accompanying sound, but there was some difficulty with synchronization. Edison also experimented with captions at this early date.In 1880 he filed a patent for a magnetic ore separator, the first of nearly sixty. He bought up deposits of low-grade iron ore which had been developed in the north of New Jersey. The process was a commercial success until the discovery of iron-rich ore in Minnesota rendered it uneconomic and uncompetitive. In 1898 cement rock was discovered in New Village, west of West Orange. Edison bought the land and started cement manufacture, using kilns twice the normal length and using half as much fuel to heat them as the normal type of kiln. In 1893 he met Henry Ford, who was building his second car, at an Edison convention. This started him on the development of a battery for an electric car on which he made over 9,000 experiments. In 1903 he sold his patent for wireless telegraphy "for a song" to Guglielmo Marconi.In 1910 Edison designed a prefabricated concrete house. In December 1914 fire destroyed three-quarters of the West Orange plant, but it was at once rebuilt, and with the threat of war Edison started to set up his own plants for making all the chemicals that he had previously been buying from Europe, such as carbolic acid, phenol, benzol, aniline dyes, etc. He was appointed President of the Navy Consulting Board, for whom, he said, he made some forty-five inventions, "but they were pigeonholed, every one of them". Thus did Edison find that the Navy did not take kindly to civilian interference.In 1927 he started the Edison Botanic Research Company, founded with similar investment from Ford and Firestone with the object of finding a substitute for overseas-produced rubber. In the first year he tested no fewer than 3,327 possible plants, in the second year, over 1,400, eventually developing a variety of Golden Rod which grew to 14 ft (4.3 m) in height. However, all this effort and money was wasted, due to the discovery of synthetic rubber.In October 1929 he was present at Henry Ford's opening of his Dearborn Museum to celebrate the fiftieth anniversary of the incandescent lamp, including a replica of the Menlo Park laboratory. He was awarded the Congressional Gold Medal and was elected to the American Academy of Sciences. He died in 1931 at his home, Glenmont; throughout the USA, lights were dimmed temporarily on the day of his funeral.[br]Principal Honours and DistinctionsMember of the American Academy of Sciences.

82 Monro, Philip Peter
SUBJECT AREA: Chemical technology[br]b. 27 May 1946 London, England[br]English biologist, inventor of a water-purification process by osmosis.[br]Monro's whole family background is engineering, an interest he did not share. Instead, he preferred biology, an enthusiasm aroused by reading the celebrated Science of Life by H.G. and G.P.Wells and Julian Huxley. Educated at a London comprehensive school, Monro found it necessary to attend evening classes while at school to take his advanced level science examinations. Lacking parental support, he could not pursue a degree course until he was 21 years old, and so he gained valuable practical experience as a research technician. He resumed his studies and took a zoology degree at Portsmouth Polytechnic. He then worked in a range of zoology and medical laboratories, culminating after twelve years as a Senior Experimental Officer at Southampton Medical School. In 1989 he relinquished his post to devote himself fall time to developing his inventions as Managing Director of Hampshire Advisory and Technical Services Ltd (HATS). Also in 1988 he obtained his PhD from Southampton University, in the field of embryology.Monro had meanwhile been demonstrating a talent for invention, mainly in microscopy. His most important invention, however, is of a water-purification system. The idea for it came from Michael Wilson of the Institute of Dental Surgery in London, who evolved a technique for osmotic production of sterile oral rehydration solutions, of particular use in treating infants suffering from diarrhoea in third-world countries. Monro broadened the original concept to include dried food, intravenous solutions and even dried blood. The process uses simple equipment and no external power and works as follows: a dry sugar/salts mixture is sealed in one compartment of a double bag, the common wall of which is a semipermeable membrane. Impure water is placed in the empty compartment and the water transfers across the membrane by the osmotic force of the sugar/salts. As the pores in the membrane exclude all viruses, bacteria and their toxins, a sterile solution is produced.With the help of a research fellowship granted for humanitarian reasons at King Alfred College, Winchester, the invention was developed to functional prototype stage in 1993, with worldwide patent protection. Commercial production was expected to follow, if sufficient financial backing were forthcoming. The process is not intended to replace large installations, but will revolutionize the small-scale production of sterile water in scattered third-world communities and in disaster areas where normal services have been disrupted.HATS was awarded First Prize in the small business category and was overall prize winner in the Toshiba Year of Invention, received a NatWest/BP award for technology and a Prince of Wales Award for Innovation.[br]Bibliography1993, with M.Wilson and W.A.M.Cutting, "Osmotic production of sterile oral rehydration solutions", Tropical Doctor 23:69–72.LRD -

90 Theater, Portuguese
There are two types of theater in Portugal: classical or "serious" theater and light theater, or the Theater of Review, largely the Revistas de Lisboa (Lisbon Reviews). Modern theater, mostly but not exclusively centered in Lisbon, experienced an unfortunate impact from official censorship during the Estado Novo (1926-74). Following laws passed in 1927, the government decreed that, as a cultural activity, any theatrical presentations that were judged "offensive in law, in morality and in decent customs" were prohibited. One consequence that derived from the risk of prohibition was that directors and playwrights began to practice self-censorship. This discouraged liberal and experimental theatrical work, weakened commercial investment in theater, and made employment in much theater a risky business, with indifferent public support.Despite these political obstacles and the usual risks and difficulties of producing live theater in competition first with emerging cinema and then with television (which began in any case only after 1957), some good theatrical work flourished. Two of the century's greatest repertory actresses, Amélia Rey-Colaço (1898-1990) and Maria Matos (1890-1962), put together talented acting companies and performed well-received classical theater. Two periods witnessed a brief diminution of censorship: following World War II (1945-47) and during Prime Minister Marcello Caetano's government (1968-74). Although Portuguese playwrights also produced comedies and dramas, some of the best productions reached the stage under the authorship of foreign playwrights: Shakespeare, George Bernard Shaw, Arthur Miller, and others.A major new phase of Portuguese serious theater began in the 1960s, with the staging of challenging plays by playwrights José Cardoso Pires, Luis Sttau Monteiro, and Bernardo Santareno. Since the Revolution of 25 April 1974, more funds for experimental theater have become available, and government censorship ceased. As in so much of Western European theater, however, the general public tended to favor not plays with serious content but techno-hits that featured foreign imports, including musicals, or homegrown musicals on familiar themes. Nevertheless, after 1974, the theater scene was enlivened, not only in Lisbon, but also in Oporto, Coimbra, and other cities.The Theater of Review, or light theater, was introduced to Portugal in the 19th century and was based largely on French models. Adapted to the Portuguese scene, the Lisbon reviews featured pageantry, costume, comic skits, music (including the ever popular fado), dance, and slapstick humor and satire. Despite censorship, its heyday occurred actually during the Estado Novo, before 1968. Of all the performing arts, the Lisbon reviews enjoyed the greatest freedom from official political censorship. Certain periods featured more limited censorship, as cited earlier (1945-47 and 1968-74). The main venue of the Theater of Review was located in central Lisbon's Parque Mayer, an amusement park that featured four review theaters: Maria Vitória, Variedades, Capitólio, and ABC.Many actors and stage designers, as well as some musicians, served their apprenticeship in the Lisbon reviews before they moved into film and television. Noted fado singers, the fadistas, and composers plied their trade in Parque Mayer and built popular followings. The subjects of the reviews, often with provocative titles, varied greatly and followed contemporary social, economic, and even political fashion and trends, but audiences especially liked satire directed against convention and custom. If political satire was not passed by the censor in the press or on television, sometimes the Lisbon reviews, by the use of indirection and allegory, could get by with subtle critiques of some personalities in politics and society. A humorous stereotyping of customs of "the people," usually conceived of as Lisbon street people or naive "country bumpkins," was also popular. To a much greater degree than in classical, serious theater, the Lisbon review audiences steadily supported this form of public presentation. But the zenith of this form of theater had been passed by the late 1960s as audiences dwindled, production expenses rose, and film and television offered competition.The hopes that governance under Prime Minister Marcello Caetano would bring a new season of freedom of expression in the light theater or serious theater were dashed by 1970-71, as censorship again bore down. With revolution in the offing, change was in the air, and could be observed in a change of review show title. A Lisbon review show title on the eve of the Revolution of 25 April 1974, was altered from: 'To See, to Hear... and Be Quiet" to the suggestive, "To See, to Hear... and to Talk." The review theater experienced several difficult years after 1980, and virtually ceased to exist in Parque Mayer. In the late 1990s, nevertheless, this traditional form of entertainment underwent a gradual revival. Audiences again began to troop to renovated theater space in the amusement park to enjoy once again new lively and humorous reviews, cast for a new century and applied to Portugal today. -
91 Dickson, William Kennedy Laurie
SUBJECT AREA: Photography, film and optics[br]b. August 1860 Brittany, Franced. 28 September 1935 Twickenham, England[br]Scottish inventor and photographer.[br]Dickson was born in France of English and Scottish parents. As a young man of almost 19 years, he wrote in 1879 to Thomas Edison in America, asking for a job. Edison replied that he was not taking on new staff at that time, but Dickson, with his mother and sisters, decided to emigrate anyway. In 1883 he contacted Edison again, and was given a job at the Goerk Street laboratory of the Edison Electric Works in New York. He soon assumed a position of responsibility as Superintendent, working on the development of electric light and power systems, and also carried out most of the photography Edison required. In 1888 he moved to the Edison West Orange laboratory, becoming Head of the ore-milling department. When Edison, inspired by Muybridge's sequence photographs of humans and animals in motion, decided to develop a motion picture apparatus, he gave the task to Dickson, whose considerable skills in mechanics, photography and electrical work made him the obvious choice. The first experiments, in 1888, were on a cylinder machine like the phonograph, in which the sequence pictures were to be taken in a spiral. This soon proved to be impractical, and work was delayed for a time while Dickson developed a new ore-milling machine. Little progress with the movie project was made until George Eastman's introduction in July 1889 of celluloid roll film, which was thin, tough, transparent and very flexible. Dickson returned to his experiments in the spring of 1891 and soon had working models of a film camera and viewer, the latter being demonstrated at the West Orange laboratory on 20 May 1891. By the early summer of 1892 the project had advanced sufficiently for commercial exploitation to begin. The Kinetograph camera used perforated 35 mm film (essentially the same as that still in use in the late twentieth century), and the kinetoscope, a peep-show viewer, took fifty feet of film running in an endless loop. Full-scale manufacture of the viewers started in 1893, and they were demonstrated on a number of occasions during that year. On 14 April 1894 the first kinetoscope parlour, with ten viewers, was opened to the public in New York. By the end of that year, the kinetoscope was seen by the public all over America and in Europe. Dickson had created the first commercially successful cinematograph system. Dickson left Edison's employment on 2 April 1895, and for a time worked with Woodville Latham on the development of his Panoptikon projector, a projection version of the kinetoscope. In December 1895 he joined with Herman Casier, Henry N.Marvin and Elias Koopman to form the American Mutoscope Company. Casier had designed the Mutoscope, an animated-picture viewer in which the sequences of pictures were printed on cards fixed radially to a drum and were flipped past the eye as the drum rotated. Dickson designed the Biograph wide-film camera to produce the picture sequences, and also a projector to show the films directly onto a screen. The large-format images gave pictures of high quality for the period; the Biograph went on public show in America in September 1896, and subsequently throughout the world, operating until around 1905. In May 1897 Dickson returned to England and set up as a producer of Biograph films, recording, among other subjects, Queen Victoria's Diamond Jubilee celebrations in 1897, Pope Leo XIII in 1898, and scenes of the Boer War in 1899 and 1900. Many of the Biograph subjects were printed as reels for the Mutoscope to produce the "what the butler saw" machines which were a feature of fairgrounds and seaside arcades until modern times. Dickson's contact with the Biograph Company, and with it his involvement in cinematography, ceased in 1911.[br]Further ReadingGordon Hendricks, 1961, The Edison Motion Picture Myth.—1966, The Kinetoscope.—1964, The Beginnings of the Biograph.BCBiographical history of technology > Dickson, William Kennedy Laurie

92 Eastman, George
SUBJECT AREA: Photography, film and optics[br]b. 12 July 1854 Waterville, New York, USAd. 14 March 1932 Rochester, New York, USA[br]American industrialist and pioneer of popular photography.[br]The young Eastman was a clerk-bookkeeper in the Rochester Savings Bank when in 1877 he took up photography. Taking lessons in the wet-plate process, he became an enthusiastic amateur photographer. However, the cumbersome equipment and noxious chemicals used in the process proved an obstacle, as he said, "It seemed to be that one ought to be able to carry less than a pack-horse load." Then he came across an account of the new gelatine dry-plate process in the British Journal of Photography of March 1878. He experimented in coating glass plates with the new emulsions, and was soon so successful that he decided to go into commercial manufacture. He devised a machine to simplify the coating of the plates, and travelled to England in July 1879 to patent it. In April 1880 he prepared to begin manufacture in a rented building in Rochester, and contacted the leading American photographic supply house, E. \& H.T.Anthony, offering them an option as agents. A local whip manufacturer, Henry A.Strong, invested $1,000 in the enterprise and the Eastman Dry Plate Company was formed on 1 January 1881. Still working at the Savings Bank, he ran the business in his spare time, and demand grew for the quality product he was producing. The fledgling company survived a near disaster in 1882 when the quality of the emulsions dropped alarmingly. Eastman later discovered this was due to impurities in the gelatine used, and this led him to test all raw materials rigorously for quality. In 1884 the company became a corporation, the Eastman Dry Plate \& Film Company, and a new product was announced. Mindful of his desire to simplify photography, Eastman, with a camera maker, William H.Walker, designed a roll-holder in which the heavy glass plates were replaced by a roll of emulsion-coated paper. The holders were made in sizes suitable for most plate cameras. Eastman designed and patented a coating machine for the large-scale production of the paper film, bringing costs down dramatically, the roll-holders were acclaimed by photographers worldwide, and prizes and medals were awarded, but Eastman was still not satisfied. The next step was to incorporate the roll-holder in a smaller, hand-held camera. His first successful design was launched in June 1888: the Kodak camera. A small box camera, it held enough paper film for 100 circular exposures, and was bought ready-loaded. After the film had been exposed, the camera was returned to Eastman's factory, where the film was removed, processed and printed, and the camera reloaded. This developing and printing service was the most revolutionary part of his invention, since at that time photographers were expected to process their own photographs, which required access to a darkroom and appropriate chemicals. The Kodak camera put photography into the hands of the countless thousands who wanted photographs without complications. Eastman's marketing slogan neatly summed up the advantage: "You Press the Button, We Do the Rest." The Kodak camera was the last product in the design of which Eastman was personally involved. His company was growing rapidly, and he recruited the most talented scientists and technicians available. New products emerged regularly—notably the first commercially produced celluloid roll film for the Kodak cameras in July 1889; this material made possible the introduction of cinematography a few years later. Eastman's philosophy of simplifying photography and reducing its costs continued to influence products: for example, the introduction of the one dollar, or five shilling, Brownie camera in 1900, which put photography in the hands of almost everyone. Over the years the Eastman Kodak Company, as it now was, grew into a giant multinational corporation with manufacturing and marketing organizations throughout the world. Eastman continued to guide the company; he pursued an enlightened policy of employee welfare and profit sharing decades before this was common in industry. He made massive donations to many concerns, notably the Massachusetts Institute of Technology, and supported schemes for the education of black people, dental welfare, calendar reform, music and many other causes, he withdrew from the day-to-day control of the company in 1925, and at last had time for recreation. On 14 March 1932, suffering from a painful terminal cancer and after tidying up his affairs, he shot himself through the heart, leaving a note: "To my friends: My work is done. Why wait?" Although Eastman's technical innovations were made mostly at the beginning of his career, the organization which he founded and guided in its formative years was responsible for many of the major advances in photography over the years.[br]Further ReadingC.Ackerman, 1929, George Eastman, Cambridge, Mass.B.Coe, 1973, George Eastman and the Early Photographers, London.BC -
93 Elder, John
[br]b. 9 March 1824 Glasgow, Scotlandd. 17 September 1869 London, England[br]Scottish engineer who introduced the compound steam engine to ships and established an important shipbuilding company in Glasgow.[br]John was the third son of David Elder. The father came from a family of millwrights and moved to Glasgow where he worked for the well-known shipbuilding firm of Napier's and was involved with improving marine engines. John was educated at Glasgow High School and then for a while at the Department of Civil Engineering at Glasgow University, where he showed great aptitude for mathematics and drawing. He spent five years as an apprentice under Robert Napier followed by two short periods of activity as a pattern-maker first and then a draughtsman in England. He returned to Scotland in 1849 to become Chief Draughtsman to Napier, but in 1852 he left to become a partner with the Glasgow general engineering company of Randolph Elliott \& Co. Shortly after his induction (at the age of 28), the engineering firm was renamed Randolph Elder \& Co.; in 1868, when the partnership expired, it became known as John Elder \& Co. From the outset Elder, with his partner, Charles Randolph, approached mechanical (especially heat) engineering in a rigorous manner. Their knowledge and understanding of entropy ensured that engine design was not a hit-and-miss affair, but one governed by recognition of the importance of the new kinetic theory of heat and with it a proper understanding of thermodynamic principles, and by systematic development. In this Elder was joined by W.J.M. Rankine, Professor of Civil Engineering and Mechanics at Glasgow University, who helped him develop the compound marine engine. Elder and Randolph built up a series of patents, which guaranteed their company's commercial success and enabled them for a while to be the sole suppliers of compound steam reciprocating machinery. Their first such engine at sea was fitted in 1854 on the SS Brandon for the Limerick Steamship Company; the ship showed an improved performance by using a third less coal, which he was able to reduce still further on later designs.Elder developed steam jacketing and recognized that, with higher pressures, triple-expansion types would be even more economical. In 1862 he patented a design of quadruple-expansion engine with reheat between cylinders and advocated the importance of balancing reciprocating parts. The effect of his improvements was to greatly reduce fuel consumption so that long sea voyages became an economic reality.His yard soon reached dimensions then unequalled on the Clyde where he employed over 4,000 workers; Elder also was always interested in the social welfare of his labour force. In 1860 the engine shops were moved to the Govan Old Shipyard, and again in 1864 to the Fairfield Shipyard, about 1 mile (1.6 km) west on the south bank of the Clyde. At Fairfield, shipbuilding was commenced, and with the patents for compounding secure, much business was placed for many years by shipowners serving long-distance trades such as South America; the Pacific Steam Navigation Company took up his ideas for their ships. In later years the yard became known as the Fairfield Shipbuilding and Engineering Company Ltd, but it remains today as one of Britain's most efficient shipyards and is known now as Kvaerner Govan Ltd.In 1869, at the age of only 45, John Elder was unanimously elected President of the Institution of Engineers and Shipbuilders in Scotland; however, before taking office and giving his eagerly awaited presidential address, he died in London from liver disease. A large multitude attended his funeral and all the engineering shops were silent as his body, which had been brought back from London to Glasgow, was carried to its resting place. In 1857 Elder had married Isabella Ure, and on his death he left her a considerable fortune, which she used generously for Govan, for Glasgow and especially the University. In 1883 she endowed the world's first Chair of Naval Architecture at the University of Glasgow, an act which was reciprocated in 1901 when the University awarded her an LLD on the occasion of its 450th anniversary.[br]Principal Honours and DistinctionsPresident, Institution of Engineers and Shipbuilders in Scotland 1869.Further ReadingObituary, 1869, Engineer 28.1889, The Dictionary of National Biography, London: Smith Elder \& Co.

94 Ford, Henry
[br]b. 30 July 1863 Dearborn, Michigan, USAd. 7 April 1947 Dearborn, Michigan, USA[br]American pioneer motor-car maker and developer of mass-production methods.[br]He was the son of an Irish immigrant farmer, William Ford, and the oldest son to survive of Mary Litogot; his mother died in 1876 with the birth of her sixth child. He went to the village school, and at the age of 16 he was apprenticed to Flower brothers' machine shop and then at the Drydock \& Engineering Works in Detroit. In 1882 he left to return to the family farm and spent some time working with a 1 1/2 hp steam engine doing odd jobs for the farming community at $3 per day. He was then employed as a demonstrator for Westinghouse steam engines. He met Clara Jane Bryant at New Year 1885 and they were married on 11 April 1888. Their only child, Edsel Bryant Ford, was born on 6 November 1893.At that time Henry worked on steam engine repairs for the Edison Illuminating Company, where he became Chief Engineer. He became one of a group working to develop a "horseless carriage" in 1896 and in June completed his first vehicle, a "quadri cycle" with a two-cylinder engine. It was built in a brick shed, which had to be partially demolished to get the carriage out.Ford became involved in motor racing, at which he was more successful than he was in starting a car-manufacturing company. Several early ventures failed, until the Ford Motor Company of 1903. By October 1908 they had started with production of the Model T. The first, of which over 15 million were built up to the end of its production in May 1927, came out with bought-out steel stampings and a planetary gearbox, and had a one-piece four-cylinder block with a bolt-on head. This was one of the most successful models built by Ford or any other motor manufacturer in the life of the motor car.Interchangeability of components was an important element in Ford's philosophy. Ford was a pioneer in the use of vanadium steel for engine components. He adopted the principles of Frederick Taylor, the pioneer of time-and-motion study, and installed the world's first moving assembly line for the production of magnetos, started in 1913. He installed blast furnaces at the factory to make his own steel, and he also promoted research and the cultivation of the soya bean, from which a plastic was derived.In October 1913 he introduced the "Five Dollar Day", almost doubling the normal rate of pay. This was a profit-sharing scheme for his employees and contained an element of a reward for good behaviour. About this time he initiated work on an agricultural tractor, the "Fordson" made by a separate company, the directors of which were Henry and his son Edsel.In 1915 he chartered the Oscar II, a "peace ship", and with fifty-five delegates sailed for Europe a week before Christmas, docking at Oslo. Their objective was to appeal to all European Heads of State to stop the war. He had hoped to persuade manufacturers to replace armaments with tractors in their production programmes. In the event, Ford took to his bed in the hotel with a chill, stayed there for five days and then sailed for New York and home. He did, however, continue to finance the peace activists who remained in Europe. Back in America, he stood for election to the US Senate but was defeated. He was probably the father of John Dahlinger, illegitimate son of Evangeline Dahlinger, a stenographer employed by the firm and on whom he lavished gifts of cars, clothes and properties. He became the owner of a weekly newspaper, the Dearborn Independent, which became the medium for the expression of many of his more unorthodox ideas. He was involved in a lawsuit with the Chicago Tribune in 1919, during which he was cross-examined on his knowledge of American history: he is reputed to have said "History is bunk". What he actually said was, "History is bunk as it is taught in schools", a very different comment. The lawyers who thus made a fool of him would have been surprised if they could have foreseen the force and energy that their actions were to release. For years Ford employed a team of specialists to scour America and Europe for furniture, artefacts and relics of all kinds, illustrating various aspects of history. Starting with the Wayside Inn from South Sudbury, Massachusetts, buildings were bought, dismantled and moved, to be reconstructed in Greenfield Village, near Dearborn. The courthouse where Abraham Lincoln had practised law and the Ohio bicycle shop where the Wright brothers built their first primitive aeroplane were added to the farmhouse where the proprietor, Henry Ford, had been born. Replicas were made of Independence Hall, Congress Hall and the old City Hall in Philadelphia, and even a reconstruction of Edison's Menlo Park laboratory was installed. The Henry Ford museum was officially opened on 21 October 1929, on the fiftieth anniversary of Edison's invention of the incandescent bulb, but it continued to be a primary preoccupation of the great American car maker until his death.Henry Ford was also responsible for a number of aeronautical developments at the Ford Airport at Dearborn. He introduced the first use of radio to guide a commercial aircraft, the first regular airmail service in the United States. He also manufactured the country's first all-metal multi-engined plane, the Ford Tri-Motor.Edsel became President of the Ford Motor Company on his father's resignation from that position on 30 December 1918. Following the end of production in May 1927 of the Model T, the replacement Model A was not in production for another six months. During this period Henry Ford, though officially retired from the presidency of the company, repeatedly interfered and countermanded the orders of his son, ostensibly the man in charge. Edsel, who died of stomach cancer at his home at Grosse Point, Detroit, on 26 May 1943, was the father of Henry Ford II. Henry Ford died at his home, "Fair Lane", four years after his son's death.[br]Bibliography1922, with S.Crowther, My Life and Work, London: Heinemann.Further ReadingR.Lacey, 1986, Ford, the Men and the Machine, London: Heinemann.

95 Gutenberg, Johann Gensfleisch zum
SUBJECT AREA: Paper and printing[br]b. c. 1394–9 Mainz, Germanyd. 3 February 1468 Mainz, Germany[br]German inventor of printing with movable type.[br]Few biographical details are known of Johann Gensfleisch zum Gutenberg, yet it has been said that he was responsible for Germany's most notable contribution to civilization. He was a goldsmith by trade, of a patrician family of the city of Mainz. He seems to have begun experiments on printing while a political exile in Strasbourg c. 1440. He returned to Mainz between 1444 and 1448 and continued his experiments, until by 1450 he had perfected his invention sufficiently to justify raising capital for its commercial exploitation.Circumstances were propitious for the invention of printing at that time. Rises in literacy and prosperity had led to the formation of a social class with the time and resources to develop a taste for reading, and the demand for reading matter had outstripped the ability of the scribes to satisfy it. The various technologies required were well established, and finally the flourishing textile industry was producing enough waste material, rag, to make paper, the only satisfactory and cheap medium for printing. There were others working along similar lines, but it was Gutenberg who achieved the successful adaptation and combination of technologies to arrive at a process by which many identical copies of a text could be produced in a wide variety of forms, of which the book was the most important. Gutenberg did make several technical innovations, however. The two-piece adjustable mould for casting types of varying width, from T to "M", was ingenious. Then he had to devise an oil-based ink suitable for inking metal type, derived from the painting materials developed by contemporary Flemish artists. Finally, probably after many experiments, he arrived at a metal alloy of distinctive composition suitable for casting type.In 1450 Gutenberg borrowed 800 guldens from Johannes Fust, a lawyer of Mainz, and two years later Fust advanced a further 800 guldens, securing for himself a partnership in Gutenberg's business. But in 1455 Fust foreclosed and the bulk of Gutenberg's equipment passed to Peter Schöffer, who was in the service of Fust and later married his daughter. Like most early printers, Gutenberg seems not to have appreciated, or at any rate to have been able to provide for, the great dilemma of the publishing trade, namely the outlay of considerable capital in advance of each publication and the slowness of the return. Gutenberg probably retained only the type for the 42- and 36-line bibles and possibly the Catholicon of 1460, an encyclopedic work compiled in the thirteenth century and whose production pointed the way to printing's role as a means of spreading knowledge. The work concluded with a short descriptive piece, or colophon, which is probably by Gutenberg himself and is the only output of his mind that we have; it manages to omit the names of both author and printer.Gutenberg seems to have abandoned printing after 1460, perhaps due to failing eyesight as well as for financial reasons, and he suffered further loss in the sack of Mainz in 1462. He received a kind of pension from the Archbishop in 1465, and on his death was buried in the Franciscan church in Mainz. The only major work to have issued for certain from Gutenberg's workshop is the great 42-line bible, begun in 1452 and completed by August 1456. The quality of this Graaf piece of printing is a tribute to Gutenberg's ability as a printer, and the soundness of his invention is borne out by the survival of the process as he left it to the world, unchanged for over three hundred years save in minor details.[br]Further ReadingA.Ruppel, 1967, Johannes Gutenberg: sein Leben und sein Werk, 3rd edn, Nieuwkoop: B.de Graaf (the standard biography), A.M.L.de Lamartine, 1960, Gutenberg, inventeur de l'imprimerie, Tallone.Scholderer, 1963, Gutenberg, Inventor of Printing, London: British Museum.S.H.Steinberg, 1974, Five Hundred Years of Printing 3rd edn, London: Penguin (provides briefer details).LRDBiographical history of technology > Gutenberg, Johann Gensfleisch zum

96 Artificial Intelligence
In my opinion, none of [these programs] does even remote justice to the complexity of human mental processes. Unlike men, "artificially intelligent" programs tend to be single minded, undistractable, and unemotional. (Neisser, 1967, p. 9)Future progress in [artificial intelligence] will depend on the development of both practical and theoretical knowledge.... As regards theoretical knowledge, some have sought a unified theory of artificial intelligence. My view is that artificial intelligence is (or soon will be) an engineering discipline since its primary goal is to build things. (Nilsson, 1971, pp. vii-viii)Most workers in AI [artificial intelligence] research and in related fields confess to a pronounced feeling of disappointment in what has been achieved in the last 25 years. Workers entered the field around 1950, and even around 1960, with high hopes that are very far from being realized in 1972. In no part of the field have the discoveries made so far produced the major impact that was then promised.... In the meantime, claims and predictions regarding the potential results of AI research had been publicized which went even farther than the expectations of the majority of workers in the field, whose embarrassments have been added to by the lamentable failure of such inflated predictions....When able and respected scientists write in letters to the present author that AI, the major goal of computing science, represents "another step in the general process of evolution"; that possibilities in the 1980s include an all-purpose intelligence on a human-scale knowledge base; that awe-inspiring possibilities suggest themselves based on machine intelligence exceeding human intelligence by the year 2000 [one has the right to be skeptical]. (Lighthill, 1972, p. 17)4) Just as Astronomy Succeeded Astrology, the Discovery of Intellectual Processes in Machines Should Lead to a Science, EventuallyJust as astronomy succeeded astrology, following Kepler's discovery of planetary regularities, the discoveries of these many principles in empirical explorations on intellectual processes in machines should lead to a science, eventually. (Minsky & Papert, 1973, p. 11)5) Problems in Machine Intelligence Arise Because Things Obvious to Any Person Are Not Represented in the ProgramMany problems arise in experiments on machine intelligence because things obvious to any person are not represented in any program. One can pull with a string, but one cannot push with one.... Simple facts like these caused serious problems when Charniak attempted to extend Bobrow's "Student" program to more realistic applications, and they have not been faced up to until now. (Minsky & Papert, 1973, p. 77)What do we mean by [a symbolic] "description"? We do not mean to suggest that our descriptions must be made of strings of ordinary language words (although they might be). The simplest kind of description is a structure in which some features of a situation are represented by single ("primitive") symbols, and relations between those features are represented by other symbols-or by other features of the way the description is put together. (Minsky & Papert, 1973, p. 11)[AI is] the use of computer programs and programming techniques to cast light on the principles of intelligence in general and human thought in particular. (Boden, 1977, p. 5)The word you look for and hardly ever see in the early AI literature is the word knowledge. They didn't believe you have to know anything, you could always rework it all.... In fact 1967 is the turning point in my mind when there was enough feeling that the old ideas of general principles had to go.... I came up with an argument for what I called the primacy of expertise, and at the time I called the other guys the generalists. (Moses, quoted in McCorduck, 1979, pp. 228-229)9) Artificial Intelligence Is Psychology in a Particularly Pure and Abstract FormThe basic idea of cognitive science is that intelligent beings are semantic engines-in other words, automatic formal systems with interpretations under which they consistently make sense. We can now see why this includes psychology and artificial intelligence on a more or less equal footing: people and intelligent computers (if and when there are any) turn out to be merely different manifestations of the same underlying phenomenon. Moreover, with universal hardware, any semantic engine can in principle be formally imitated by a computer if only the right program can be found. And that will guarantee semantic imitation as well, since (given the appropriate formal behavior) the semantics is "taking care of itself" anyway. Thus we also see why, from this perspective, artificial intelligence can be regarded as psychology in a particularly pure and abstract form. The same fundamental structures are under investigation, but in AI, all the relevant parameters are under direct experimental control (in the programming), without any messy physiology or ethics to get in the way. (Haugeland, 1981b, p. 31)There are many different kinds of reasoning one might imagine:Formal reasoning involves the syntactic manipulation of data structures to deduce new ones following prespecified rules of inference. Mathematical logic is the archetypical formal representation. Procedural reasoning uses simulation to answer questions and solve problems. When we use a program to answer What is the sum of 3 and 4? it uses, or "runs," a procedural model of arithmetic. Reasoning by analogy seems to be a very natural mode of thought for humans but, so far, difficult to accomplish in AI programs. The idea is that when you ask the question Can robins fly? the system might reason that "robins are like sparrows, and I know that sparrows can fly, so robins probably can fly."Generalization and abstraction are also natural reasoning process for humans that are difficult to pin down well enough to implement in a program. If one knows that Robins have wings, that Sparrows have wings, and that Blue jays have wings, eventually one will believe that All birds have wings. This capability may be at the core of most human learning, but it has not yet become a useful technique in AI.... Meta- level reasoning is demonstrated by the way one answers the question What is Paul Newman's telephone number? You might reason that "if I knew Paul Newman's number, I would know that I knew it, because it is a notable fact." This involves using "knowledge about what you know," in particular, about the extent of your knowledge and about the importance of certain facts. Recent research in psychology and AI indicates that meta-level reasoning may play a central role in human cognitive processing. (Barr & Feigenbaum, 1981, pp. 146-147)Suffice it to say that programs already exist that can do things-or, at the very least, appear to be beginning to do things-which ill-informed critics have asserted a priori to be impossible. Examples include: perceiving in a holistic as opposed to an atomistic way; using language creatively; translating sensibly from one language to another by way of a language-neutral semantic representation; planning acts in a broad and sketchy fashion, the details being decided only in execution; distinguishing between different species of emotional reaction according to the psychological context of the subject. (Boden, 1981, p. 33)Can the synthesis of Man and Machine ever be stable, or will the purely organic component become such a hindrance that it has to be discarded? If this eventually happens-and I have... good reasons for thinking that it must-we have nothing to regret and certainly nothing to fear. (Clarke, 1984, p. 243)The thesis of GOFAI... is not that the processes underlying intelligence can be described symbolically... but that they are symbolic. (Haugeland, 1985, p. 113)14) Artificial Intelligence Provides a Useful Approach to Psychological and Psychiatric Theory FormationIt is all very well formulating psychological and psychiatric theories verbally but, when using natural language (even technical jargon), it is difficult to recognise when a theory is complete; oversights are all too easily made, gaps too readily left. This is a point which is generally recognised to be true and it is for precisely this reason that the behavioural sciences attempt to follow the natural sciences in using "classical" mathematics as a more rigorous descriptive language. However, it is an unfortunate fact that, with a few notable exceptions, there has been a marked lack of success in this application. It is my belief that a different approach-a different mathematics-is needed, and that AI provides just this approach. (Hand, quoted in Hand, 1985, pp. 6-7)We might distinguish among four kinds of AI.Research of this kind involves building and programming computers to perform tasks which, to paraphrase Marvin Minsky, would require intelligence if they were done by us. Researchers in nonpsychological AI make no claims whatsoever about the psychological realism of their programs or the devices they build, that is, about whether or not computers perform tasks as humans do.Research here is guided by the view that the computer is a useful tool in the study of mind. In particular, we can write computer programs or build devices that simulate alleged psychological processes in humans and then test our predictions about how the alleged processes work. We can weave these programs and devices together with other programs and devices that simulate different alleged mental processes and thereby test the degree to which the AI system as a whole simulates human mentality. According to weak psychological AI, working with computer models is a way of refining and testing hypotheses about processes that are allegedly realized in human minds.... According to this view, our minds are computers and therefore can be duplicated by other computers. Sherry Turkle writes that the "real ambition is of mythic proportions, making a general purpose intelligence, a mind." (Turkle, 1984, p. 240) The authors of a major text announce that "the ultimate goal of AI research is to build a person or, more humbly, an animal." (Charniak & McDermott, 1985, p. 7)Research in this field, like strong psychological AI, takes seriously the functionalist view that mentality can be realized in many different types of physical devices. Suprapsychological AI, however, accuses strong psychological AI of being chauvinisticof being only interested in human intelligence! Suprapsychological AI claims to be interested in all the conceivable ways intelligence can be realized. (Flanagan, 1991, pp. 241-242)16) Determination of Relevance of Rules in Particular ContextsEven if the [rules] were stored in a context-free form the computer still couldn't use them. To do that the computer requires rules enabling it to draw on just those [ rules] which are relevant in each particular context. Determination of relevance will have to be based on further facts and rules, but the question will again arise as to which facts and rules are relevant for making each particular determination. One could always invoke further facts and rules to answer this question, but of course these must be only the relevant ones. And so it goes. It seems that AI workers will never be able to get started here unless they can settle the problem of relevance beforehand by cataloguing types of context and listing just those facts which are relevant in each. (Dreyfus & Dreyfus, 1986, p. 80)Perhaps the single most important idea to artificial intelligence is that there is no fundamental difference between form and content, that meaning can be captured in a set of symbols such as a semantic net. (G. Johnson, 1986, p. 250)Artificial intelligence is based on the assumption that the mind can be described as some kind of formal system manipulating symbols that stand for things in the world. Thus it doesn't matter what the brain is made of, or what it uses for tokens in the great game of thinking. Using an equivalent set of tokens and rules, we can do thinking with a digital computer, just as we can play chess using cups, salt and pepper shakers, knives, forks, and spoons. Using the right software, one system (the mind) can be mapped into the other (the computer). (G. Johnson, 1986, p. 250)19) A Statement of the Primary and Secondary Purposes of Artificial IntelligenceThe primary goal of Artificial Intelligence is to make machines smarter.The secondary goals of Artificial Intelligence are to understand what intelligence is (the Nobel laureate purpose) and to make machines more useful (the entrepreneurial purpose). (Winston, 1987, p. 1)The theoretical ideas of older branches of engineering are captured in the language of mathematics. We contend that mathematical logic provides the basis for theory in AI. Although many computer scientists already count logic as fundamental to computer science in general, we put forward an even stronger form of the logic-is-important argument....AI deals mainly with the problem of representing and using declarative (as opposed to procedural) knowledge. Declarative knowledge is the kind that is expressed as sentences, and AI needs a language in which to state these sentences. Because the languages in which this knowledge usually is originally captured (natural languages such as English) are not suitable for computer representations, some other language with the appropriate properties must be used. It turns out, we think, that the appropriate properties include at least those that have been uppermost in the minds of logicians in their development of logical languages such as the predicate calculus. Thus, we think that any language for expressing knowledge in AI systems must be at least as expressive as the first-order predicate calculus. (Genesereth & Nilsson, 1987, p. viii)21) Perceptual Structures Can Be Represented as Lists of Elementary PropositionsIn artificial intelligence studies, perceptual structures are represented as assemblages of description lists, the elementary components of which are propositions asserting that certain relations hold among elements. (Chase & Simon, 1988, p. 490)Artificial intelligence (AI) is sometimes defined as the study of how to build and/or program computers to enable them to do the sorts of things that minds can do. Some of these things are commonly regarded as requiring intelligence: offering a medical diagnosis and/or prescription, giving legal or scientific advice, proving theorems in logic or mathematics. Others are not, because they can be done by all normal adults irrespective of educational background (and sometimes by non-human animals too), and typically involve no conscious control: seeing things in sunlight and shadows, finding a path through cluttered terrain, fitting pegs into holes, speaking one's own native tongue, and using one's common sense. Because it covers AI research dealing with both these classes of mental capacity, this definition is preferable to one describing AI as making computers do "things that would require intelligence if done by people." However, it presupposes that computers could do what minds can do, that they might really diagnose, advise, infer, and understand. One could avoid this problematic assumption (and also side-step questions about whether computers do things in the same way as we do) by defining AI instead as "the development of computers whose observable performance has features which in humans we would attribute to mental processes." This bland characterization would be acceptable to some AI workers, especially amongst those focusing on the production of technological tools for commercial purposes. But many others would favour a more controversial definition, seeing AI as the science of intelligence in general-or, more accurately, as the intellectual core of cognitive science. As such, its goal is to provide a systematic theory that can explain (and perhaps enable us to replicate) both the general categories of intentionality and the diverse psychological capacities grounded in them. (Boden, 1990b, pp. 1-2)Because the ability to store data somewhat corresponds to what we call memory in human beings, and because the ability to follow logical procedures somewhat corresponds to what we call reasoning in human beings, many members of the cult have concluded that what computers do somewhat corresponds to what we call thinking. It is no great difficulty to persuade the general public of that conclusion since computers process data very fast in small spaces well below the level of visibility; they do not look like other machines when they are at work. They seem to be running along as smoothly and silently as the brain does when it remembers and reasons and thinks. On the other hand, those who design and build computers know exactly how the machines are working down in the hidden depths of their semiconductors. Computers can be taken apart, scrutinized, and put back together. Their activities can be tracked, analyzed, measured, and thus clearly understood-which is far from possible with the brain. This gives rise to the tempting assumption on the part of the builders and designers that computers can tell us something about brains, indeed, that the computer can serve as a model of the mind, which then comes to be seen as some manner of information processing machine, and possibly not as good at the job as the machine. (Roszak, 1994, pp. xiv-xv)The inner workings of the human mind are far more intricate than the most complicated systems of modern technology. Researchers in the field of artificial intelligence have been attempting to develop programs that will enable computers to display intelligent behavior. Although this field has been an active one for more than thirty-five years and has had many notable successes, AI researchers still do not know how to create a program that matches human intelligence. No existing program can recall facts, solve problems, reason, learn, and process language with human facility. This lack of success has occurred not because computers are inferior to human brains but rather because we do not yet know in sufficient detail how intelligence is organized in the brain.

A switchboard as defined in the National Electrical Code is a large single panel, frame, or assembly of panels on which are mounted, on the face or back or both switches, overcurrent and other protective devices, buses, and, usually, instruments.
Switchboards are generally accessible from the rear as well as from the front and are not intended to be installed in cabinets.
The types of switchboards, classified by basic features of construction, are as follows:
1. Live-front vertical panels
2. Dead-front boards
3. Safety enclosed boards( metal-clad)
[American electricians’ handbook]
The switchboard plays an essential role in the availability of electric power, while meeting the needs of personal and property safety.
Its definition, design and installation are based on precise rules; there is no place for improvisation.
The IEC 61439 standard aims to better define " low-voltage switchgear and controlgear assemblies", ensuring that the specified performances are reached.
It specifies in particular:
> the responsibilities of each player, distinguishing those of the original equipment manufacturer - the organization that performed the original design and associated verification of an assembly in accordance with the standard, and of the assembly manufacturer - the organization taking responsibility for the finished assembly;
> the design and verification rules, constituting a benchmark for product certification.
All the component parts of the electrical switchboard are concerned by the IEC 61439 standard.
Equipment produced in accordance with the requirements of this switchboard standard ensures the safety and reliability of the installation.
A switchboard must comply with the requirements of standard IEC 61439-1 and 2 to guarantee the safety and reliability of the installation.
Managers of installations, fully aware of the professional and legal liabilities weighing on their company and on themselves, demand a high level of safety for the electrical installation.
What is more, the serious economic consequences of prolonged halts in production mean that the electrical switchboard must provide excellent continuity of service, whatever the operating conditions.
[Schneider Electric]НКУ играет главную роль в обеспечении электроэнергией, удовлетворяя при этом всем требованиям по безопасности людей и сохранности имущества.
Выбор конструкции, проектирование и монтаж основаны на чётких правилах, не допускающих никакой импровизации.
Требования к низковольтным комплектным устройствам распределения и управления сформулированы в стандарте МЭК 61439 (ГОСТ Р 51321. 1-2000).
В частности, он определяет:
> распределение ответственности между изготовителем НКУ - организацией, разработавшей конструкцию НКУ и проверившей его на соответствие требованиям стандарта, и сборщиком – организацией, выполнившей сборку НКУ;
> конструкцию, технические характеристики, виды и методы испытаний НКУ.
В стандарте МЭК 61439 (ГОСТ Р 51321. 1-2000) описываются все компоненты НКУ.
Оборудование, изготовленное в соответствии с требованиями этого стандарта, обеспечивает безопасность и надежность электроустановки.
Для того чтобы гарантировать безопасность эксплуатации и надежность работы электроустановки, распределительный щит должен соответствовать требованиям стандарта МЭК 61439-1 и 2.
Лица, ответственные за электроустановки, должны быть полностью осведомлены о профессиональной и юридической ответственности, возложенной на их компанию и на них лично, за обеспечение высокого уровня безопасности эксплуатации этих электроустановок.
Кроме того, поскольку длительные перерывы производства приводят к серьезным экономическим последствиям, электрический распределительный щит должен обеспечивать надежную и бесперебойную работу независимо от условий эксплуатации.
[Перевод Интент]LV switchgear assemblies are undoubtedly the components of the electric installation more subject to the direct intervention of personnel (operations, maintenance, etc.) and for this reason users demand from them higher and higher safety requirements.
The compliance of an assembly with the state of the art and therefore, presumptively, with the relevant technical Standard, cannot be based only on the fact that the components which constitute it comply with the state of the art and therefore, at least presumptively, with the relevant technical standards.
In other words, the whole assembly must be designed, built and tested in compliance with the state of the art.
Since the assemblies under consideration are low voltage equipment, their rated voltage shall not exceed 1000 Va.c. or 1500 Vd.c. As regards currents, neither upper nor lower limits are provided in the application field of this Standard.
The Standard IEC 60439-1 states the construction, safety and maintenance requirements for low voltage switchgear and controlgear assemblies, without dealing with the functional aspects which remain a competence of the designer of the plant for which the assembly is intended.
[ABB]Низковольтные комплектные устройства (НКУ), вне всякого сомнения, являются частями электроустановок, которые наиболее подвержены непосредственному вмешательству оперативного, обслуживающего и т. п. персонала. Вот почему требования потребителей к безопасности НКУ становятся все выше и выше.
Соответствие НКУ современному положению дел и вследствие этого, гипотетически, соответствующим техническим стандартам, не может основываться только на том факте, что составляющие НКУ компоненты соответствуют современному состоянию дел и поэтому, по крайней мере, гипотетически, - соответствующим техническим стандартам
Другими словами, НКУ должно быть разработано, изготовлено и испытано в соответствии с современными требованиями.
Мы рассматриваем низковольтные комплектные устройства и это означает, что их номинальное напряжение не превышает 1000 В переменного тока или 1500 В постоянного тока. Что касается тока, то ни верхнее, ни нижнее значение стандартами, относящимися к данной области, не оговариваются
Стандарт МЭК 60439-1 устанавливает требования к конструкции, безопасности и техническому обслуживанию низковольтных комплектных устройств без учета их функций, полагая, что функции НКУ являются компетенцией проектировщиков электроустановки, частью которых эти НКУ являются.

Для РУ 0,4 кВ применяются сборки низкого напряжения с предохранителями и вертикальным расположением фаз одного присоединения.
На ПС применяются открытые (ОРУ), закрытые (ЗРУ) или комплектные (КРУ) распределительные устройства.
[ http://energy-ua.com/elektricheskie-p/klassifikatsiya.html]
В общем случае ПС и РУ являются составной частью электроустановок, которые различаются:
-
по назначению:
- генерирующие,
- преобразовательно-распределительные,
-
потребительские.
Генерирующие электроустановки служат для выработки электроэнергии, преобразовательно-распределительные электроустановки преобразуют электроэнергию в удобный для передачи и потребления вид, передают ее и распределяют между потребителями;
-
по роду тока:
- постоянного тока,
- переменного тока.
-
по напряжению:
- до 1000 В,
- выше 1000 В.
Шкала номинальных напряжений ограничена сравнительно небольшим числом стандартных значений, благодаря чему изготавливается небольшое число типоразмеров машин и оборудования, а электросети выполняются более экономичными. В установках трехфазного тока номинальным напряжением принято считать напряжение между фазами (междуфазовое напряжение). Согласно ГОСТ 29322—92 установлена следующая шкала номинальных напряжений:
для электросетей переменного тока частотой 50 Гц междуфазовое напряжение должно быть: 12, 24, 36, 42, 127, 220, 380 В; 3, 6, 10, 20, 35, 110, 150, 220, 330, 500, 750 и 1150 кВ;
для электросетей постоянного тока: 12, 24, 36, 48, 60, 110, 220, 440, 660, 825, 3000 В и выше.-
по способу присоединения к электросети ПС разделяются на:
- тупиковые (блочные),
- ответвительные (блочные),
- проходные (транзитные)
- узловые.
Тупиковые ПС получают питание по одной или двум тупиковым ВЛ.
Ответвительные ПС присоединяются ответвлением к одной или двум проходящим ВЛ с односторонним или двухсторонним питанием.
Проходные ПС включаются в рассечку одной или двух проходящих ВЛ с односторонним или двухсторонним питанием.
Узловые ПС кроме питающих имеют отходящие радиальные или транзитные ВЛ.-
по способу управления ПС могут быть:
- только с телесигнализацией,
- телеуправляемыми с телесигнализацией,
- с телесигнализацией и управлением с общеподстанционного пункта управления (ОПУ).
Подстанции оперативно обслуживаются постоянным дежурным персоналом на щите управления, дежурными на дому или оперативно-выездными бригадами (ОВБ). Ремонт ПС осуществляется специализированными выездными бригадами централизованного ремонта или местным персоналом подстанции.
В РУ напряжением до 1000 В провода, шины, аппараты, приборы и конструкции выбирают как по нормальным условиям работы (напряжению и току), так и по термическим и динамическим воздействиям токов коротких замыканий (КЗ) или предельно допустимой отключаемой мощности.
В РУ и ПС напряжением выше 1000 В расстояния между электрооборудованием, аппаратами, токоведущими частями, изоляторами, ограждениями и конструкциями устанавливаются так, чтобы при нормальном режиме работы электроустановки возникающие физические явления (температура нагрева, электрическая дуга, выброс газов, искрение и др.) не могли привести к повреждению оборудования и КЗ.[ http://energy-ua.com/elektricheskie-p/klassifikatsiya.html]
Several different classifications of switchgear can be made:- By the current rating.
-
By interrupting rating (maximum short circuit current that the device can safely interrupt)
- Circuit breakers can open and close on fault currents
- Load-break/Load-make switches can switch normal system load currents
- Isolators may only be operated while the circuit is dead, or the load current is very small.
-
By voltage class:
- Low voltage (less than 1,000 volts AC)
- Medium voltage (1,000–35,000 volts AC)
- High voltage (more than 35,000 volts AC)
-
By insulating medium:
-
By construction type:
- Indoor (further classified by IP (Ingress Protection) class or NEMA enclosure type)
- Outdoor
- Industrial
- Utility
- Marine
- Draw-out elements (removable without many tools)
- Fixed elements (bolted fasteners)
- Live-front
- Dead-front
- Open
- Metal-enclosed
- Metal-clad
- Metal enclosed & Metal clad
- Arc-resistant
-
By IEC degree of internal separation
- No Separation (Form 1)
- Busbars separated from functional units (Form 2a, 2b, 3a, 3b, 4a, 4b)
- Terminals for external conductors separated from busbars (Form 2b, 3b, 4a, 4b)
- Terminals for external conductors separated from functional units but not from each other (Form 3a, 3b)
- Functional units separated from each other (Form 3a, 3b, 4a, 4b)
- Terminals for external conductors separated from each other (Form 4a, 4b)
- Terminals for external conductors separate from their associated functional unit (Form 4b)
-
By interrupting device:
-
By operating method:
- Manually operated
- Motor/stored energy operated
- Solenoid operated
-
By type of current:
-
By application:
-
By purpose
- Isolating switches (disconnectors)
- Load-break switches.
- Grounding (earthing) switches
A single line-up may incorporate several different types of devices, for example, air-insulated bus, vacuum circuit breakers, and manually operated switches may all exist in the same row of cubicles.
Ratings, design, specifications and details of switchgear are set by a multitude of standards. In North America mostly IEEE and ANSI standards are used, much of the rest of the world uses IEC standards, sometimes with local national derivatives or variations.

[IEV number 826-16-08]Distribution switchboards, including the Main LV Switchboard (MLVS), are critical to the dependability of an electrical installation. They must comply with well-defined standards governing the design and construction of LV switchgear assemblies
A distribution switchboard is the point at which an incoming-power supply divides into separate circuits, each of which is controlled and protected by the fuses or switchgear of the switchboard. A distribution switchboard is divided into a number of functional units, each comprising all the electrical and mechanical elements that contribute to the fulfilment of a given function. It represents a key link in the dependability chain.
Consequently, the type of distribution switchboard must be perfectly adapted to its application. Its design and construction must comply with applicable standards and working practises.
