10 Bakewell, Frederick C.
SUBJECT AREA: Telecommunications[br]fl. 1850s[br]British inventor of the "copying telegraph", the basis of facsimile transmission.[br]Although little appears to be known about his life, Bakewell deserves a place in this dictionary for a single invention that was to have a significant impact upon communication. The invention of photography early in the nineteenth century soon led to a desire to transmit images over a distance. Although telegraphy was still very much in its infancy, Bakewell realized that the key to a viable system of facsimile, as it came to be known, was to dissect the image to be transmitted sequentially by scanning it in a series of parallel lines with some sort of sensor and to synchronously reconstruct it at the receiving end—a process that anticipated the way in which modern television works. To this end the line image was drawn with varnish on a sheet of tin foil, which was then wrapped around a cylinder. As the cylinder was rotated, presumably by some kind of regulated clockwork mechanism similar to that used later in the early phonographs of Edison, an electrical contact driven by a screw thread caused the image to be scanned along a spiral path, giving a series of on-off signals. At the receiving end, instead of the tin foil, a sheet of paper wetted with a suitable chemical was darkened by the current pulses as they arrived.A practicable system did not become possible until a dry form of receiving-paper that was insensitive to light became available in the 1930s; once established, however, the technique remained the basis of commercial machines into the 1980s.[br]Bibliography1853, Electric Science.1857, A Manual of Electricity.Further ReadingJ.Malster \& M.J.Bowden, 1976, "Facsimile.

12 Hipp, Matthäus
[br]b. 25 October 1813 Blaubeuren, Germanyd. 3 May 1893 Zurich, Switzerland[br]German inventor and entrepreneur who produced the first reliable electric clock.[br]After serving an apprenticeship with a clock-maker in Blaubeuren, Hipp worked for various clockmakers before setting up his own workshop in Reutlingen in 1840. In 1842 he made his first electric clock with an ingenious toggle mechanism for switching the current, although he claimed that the idea had occurred to him eight years earlier. The switching mechanism was the Achilles' heel of early electric clocks. It was usually operated by the pendulum and it presented the designer with a dilemma: if the switch made a firm contact it adversely affected the timekeeping, but if the contact was lightened it sometimes failed to operate due to dirt or corrosion on the contacts. The Hipp toggle switch overcame this problem by operating only when the amplitude of the pendulum dropped below a certain value. As this occurred infrequently, the contact pressure could be increased to provide reliable switching without adversely affecting the timekeeping. It is an indication of the effectiveness of the Hipp toggle that it was used in clocks for over one hundred years and was adopted by many other makers in addition to Hipp and his successor Favag. It was generally preferred for its reliability rather than its precision, although a regulator made in 1881 for the observatory at Neuchâtel performed creditably. This regulator was enclosed in an airtight case at low pressure, eliminating errors due to changes in barometric pressure. This practice later became standard for observatory regulators such as those of Riefler and Shortt. The ability of the Hipp toggle to provide more power when the clock was subjected to an increased load made it particularly suitable for use in turret clocks, whose hands were exposed to the vagaries of the weather. Hipp also improved the operation of slave dials, which were advanced periodically by an electrical impulse from a master clock. If the electrical contacts "chattered" and produced several impulses instead of a single sharp impulse, the slave dials would not indicate the correct time. Hipp solved this problem by producing master clocks which delivered impulses that alternated in polarity, and slave dials which only advanced when the polarity was changed in this way. Polarized impulses delivered every minute became the standard practice for slave dials used on the European continent. Hipp also improved Wheatstone's chronoscope, an instrument that was used for measuring very short intervals of time (such as those involved in ballistics).[br]Principal Honours and DistinctionsHonorary doctorate, University of Zurich 1875.Further ReadingNeue deutsche Biographie, 1972, Vol. 9, Berlin, pp. 199–200."Hipp's sich selbst conrolirende Uhr", Dinglers polytechnisches Journal (1843), 88:258– 64 (the first description of the Hipp toggle).F.Hope-Jones, 1949, Electrical Timekeeping, 2nd edn, London, pp. 62–6, 97–8 (a modern description in English of the Hipp toggle and the slave dial).C.A.Aked, 1983, "Electrical precision", Antiquarian Horology 14:172–81 (describes the observatory clock at Neuchâtel).DV -

15 Paul, Robert William
[br]b. 3 October 1869 Highbury, London, Englandd. 28 March 1943 London, England[br]English scientific instrument maker, inventor of the Unipivot electrical measuring instrument, and pioneer of cinematography.[br]Paul was educated at the City of London School and Finsbury Technical College. He worked first for a short time in the Bell Telephone Works in Antwerp, Belgium, and then in the electrical instrument shop of Elliott Brothers in the Strand until 1891, when he opened an instrument-making business at 44 Hatton Garden, London. He specialized in the design and manufacture of electrical instruments, including the Ayrton Mather galvanometer. In 1902, with a purpose-built factory, he began large batch production of his instruments. He also opened a factory in New York, where uncalibrated instruments from England were calibrated for American customers. In 1903 Paul introduced the Unipivot galvanometer, in which the coil was supported at the centre of gravity of the moving system on a single pivot. The pivotal friction was less than in a conventional instrument and could be used without accurate levelling, the sensitivity being far beyond that of any pivoted galvanometer then in existence.In 1894 Paul was asked by two entrepreneurs to make copies of Edison's kinetoscope, the pioneering peep-show moving-picture viewer, which had just arrived in London. Discovering that Edison had omitted to patent the machine in England, and observing that there was considerable demand for the machine from show-people, he began production, making six before the end of the year. Altogether, he made about sixty-six units, some of which were exported. Although Edison's machine was not patented, his films were certainly copyrighted, so Paul now needed a cinematographic camera to make new subjects for his customers. Early in 1895 he came into contact with Birt Acres, who was also working on the design of a movie camera. Acres's design was somewhat impractical, but Paul constructed a working model with which Acres filmed the Oxford and Cambridge Boat Race on 30 March, and the Derby at Epsom on 29 May. Paul was unhappy with the inefficient design, and developed a new intermittent mechanism based on the principle of the Maltese cross. Despite having signed a ten-year agreement with Paul, Acres split with him on 12 July 1895, after having unilaterally patented their original camera design on 27 May. By the early weeks of 1896, Paul had developed a projector mechanism that also used the Maltese cross and which he demonstrated at the Finsbury Technical College on 20 February 1896. His Theatrograph was intended for sale, and was shown in a number of venues in London during March, notably at the Alhambra Theatre in Leicester Square. There the renamed Animatographe was used to show, among other subjects, the Derby of 1896, which was won by the Prince of Wales's horse "Persimmon" and the film of which was shown the next day to enthusiastic crowds. The production of films turned out to be quite profitable: in the first year of the business, from March 1896, Paul made a net profit of £12,838 on a capital outlay of about £1,000. By the end of the year there were at least five shows running in London that were using Paul's projectors and screening films made by him or his staff.Paul played a major part in establishing the film business in England through his readiness to sell apparatus at a time when most of his rivals reserved their equipment for sole exploitation. He went on to become a leading producer of films, specializing in trick effects, many of which he pioneered. He was affectionately known in the trade as "Daddy Paul", truly considered to be the "father" of the British film industry. He continued to appreciate fully the possibilities of cinematography for scientific work, and in collaboration with Professor Silvanus P.Thompson films were made to illustrate various phenomena to students.Paul ended his involvement with film making in 1910 to concentrate on his instrument business; on his retirement in 1920, this was amalgamated with the Cambridge Instrument Company. In his will he left shares valued at over £100,000 to form the R.W.Paul Instrument Fund, to be administered by the Institution of Electrical Engineers, of which he had been a member since 1887. The fund was to provide instruments of an unusual nature to assist physical research.[br]Principal Honours and DistinctionsFellow of the Physical Society 1920.

17 Siemens, Sir Charles William
[br]b. 4 April 1823 Lenthe, Germanyd. 19 November 1883 London, England[br]German/British metallurgist and inventory pioneer of the regenerative principle and open-hearth steelmaking.[br]Born Carl Wilhelm, he attended craft schools in Lübeck and Magdeburg, followed by an intensive course in natural science at Göttingen as a pupil of Weber. At the age of 19 Siemens travelled to England and sold an electroplating process developed by his brother Werner Siemens to Richard Elkington, who was already established in the plating business. From 1843 to 1844 he obtained practical experience in the Magdeburg works of Count Stolburg. He settled in England in 1844 and later assumed British nationality, but maintained close contact with his brother Werner, who in 1847 had co-founded the firm Siemens \& Halske in Berlin to manufacture telegraphic equipment. William began to develop his regenerative principle of waste-heat recovery and in 1856 his brother Frederick (1826–1904) took out a British patent for heat regeneration, by which hot waste gases were passed through a honeycomb of fire-bricks. When they became hot, the gases were switched to a second mass of fire-bricks and incoming air and fuel gas were led through the hot bricks. By alternating the two gas flows, high temperatures could be reached and considerable fuel economies achieved. By 1861 the two brothers had incorporated producer gas fuel, made by gasifying low-grade coal.Heat regeneration was first applied in ironmaking by Cowper in 1857 for heating the air blast in blast furnaces. The first regenerative furnace was set up in Birmingham in 1860 for glassmaking. The first such furnace for making steel was developed in France by Pierre Martin and his father, Emile, in 1863. Siemens found British steelmakers reluctant to adopt the principle so in 1866 he rented a small works in Birmingham to develop his open-hearth steelmaking furnace, which he patented the following year. The process gradually made headway; as well as achieving high temperatures and saving fuel, it was slower than Bessemer's process, permitting greater control over the content of the steel. By 1900 the tonnage of open-hearth steel exceeded that produced by the Bessemer process.In 1872 Siemens played a major part in founding the Society of Telegraph Engineers (from which the Institution of Electrical Engineers evolved), serving as its first President. He became President for the second time in 1878. He built a cable works at Charlton, London, where the cable could be loaded directly into the holds of ships moored on the Thames. In 1873, together with William Froude, a British shipbuilder, he designed the Faraday, the first specialized vessel for Atlantic cable laying. The successful laying of a cable from Europe to the United States was completed in 1875, and a further five transatlantic cables were laid by the Faraday over the following decade.The Siemens factory in Charlton also supplied equipment for some of the earliest electric-lighting installations in London, including the British Museum in 1879 and the Savoy Theatre in 1882, the first theatre in Britain to be fully illuminated by electricity. The pioneer electric-tramway system of 1883 at Portrush, Northern Ireland, was an opportunity for the Siemens company to demonstrate its equipment.[br]Principal Honours and DistinctionsKnighted 1883.

18 Muybridge, Eadweard
SUBJECT AREA: Photography, film and optics[br]b. 9 April 1830 Kingston upon Thames, Englandd. 8 May 1904 Kingston upon Thames, England[br]English photographer and pioneer of sequence photography of movement.[br]He was born Edward Muggeridge, but later changed his name, taking the Saxon spelling of his first name and altering his surname, first to Muygridge and then to Muybridge. He emigrated to America in 1851, working in New York in bookbinding and selling as a commission agent for the London Printing and Publishing Company. Through contact with a New York daguerreotypist, Silas T.Selleck, he acquired an interest in photography that developed after his move to California in 1855. On a visit to England in 1860 he learned the wet-collodion process from a friend, Arthur Brown, and acquired the best photographic equipment available in London before returning to America. In 1867, under his trade pseudonym "Helios", he set out to record the scenery of the Far West with his mobile dark-room, christened "The Flying Studio".His reputation as a photographer of the first rank spread, and he was commissioned to record the survey visit of Major-General Henry W.Halleck to Alaska and also to record the territory through which the Central Pacific Railroad was being constructed. Perhaps because of this latter project, he was approached by the President of the Central Pacific, Leland Stanford, to attempt to photograph a horse trotting at speed. There was a long-standing controversy among racing men as to whether a trotting horse had all four hooves off the ground at any point; Stanford felt that it did, and hoped than an "instantaneous" photograph would settle the matter once and for all. In May 1872 Muybridge photographed the horse "Occident", but without any great success because the current wet-collodion process normally required many seconds, even in a good light, for a good result. In April 1873 he managed to produce some better negatives, in which a recognizable silhouette of the horse showed all four feet above the ground at the same time.Soon after, Muybridge left his young wife, Flora, in San Francisco to go with the army sent to put down the revolt of the Modoc Indians. While he was busy photographing the scenery and the combatants, his wife had an affair with a Major Harry Larkyns. On his return, finding his wife pregnant, he had several confrontations with Larkyns, which culminated in his shooting him dead. At his trial for murder, in February 1875, Muybridge was acquitted by the jury on the grounds of justifiable homicide; he left soon after on a long trip to South America.He again took up his photographic work when he returned to North America and Stanford asked him to take up the action-photography project once more. Using a new shutter design he had developed while on his trip south, and which would operate in as little as 1/1,000 of a second, he obtained more detailed pictures of "Occident" in July 1877. He then devised a new scheme, which Stanford sponsored at his farm at Palo Alto. A 50 ft (15 m) long shed was constructed, containing twelve cameras side by side, and a white background marked off with vertical, numbered lines was set up. Each camera was fitted with Muybridge's highspeed shutter, which was released by an electromagnetic catch. Thin threads stretched across the track were broken by the horse as it moved along, closing spring electrical contacts which released each shutter in turn. Thus, in about half a second, twelve photographs were obtained that showed all the phases of the movement.Although the pictures were still little more than silhouettes, they were very sharp, and sequences published in scientific and photographic journals throughout the world excited considerable attention. By replacing the threads with an electrical commutator device, which allowed the release of the shutters at precise intervals, Muybridge was able to take series of actions by other animals and humans. From 1880 he lectured in America and Europe, projecting his results in motion on the screen with his Zoopraxiscope projector. In August 1883 he received a grant of $40,000 from the University of Pennsylvania to carry on his work there. Using the vastly improved gelatine dry-plate process and new, improved multiple-camera apparatus, during 1884 and 1885 he produced over 100,000 photographs, of which 20,000 were reproduced in Animal Locomotion in 1887. The subjects were animals of all kinds, and human figures, mostly nude, in a wide range of activities. The quality of the photographs was extremely good, and the publication attracted considerable attention and praise.Muybridge returned to England in 1894; his last publications were Animals in Motion (1899) and The Human Figure in Motion (1901). His influence on the world of art was enormous, over-turning the conventional representations of action hitherto used by artists. His work in pioneering the use of sequence photography led to the science of chronophotography developed by Marey and others, and stimulated many inventors, notably Thomas Edison to work which led to the introduction of cinematography in the 1890s.[br]Bibliography1887, Animal Locomotion, Philadelphia.1893, Descriptive Zoopraxography, Pennsylvania. 1899, Animals in Motion, London.1901, The Human Figure in Motion, London.Further Reading1973, Eadweard Muybridge: The Stanford Years, Stanford.G.Hendricks, 1975, Muybridge: The Father of the Motion Picture, New York.

19 Volta, Alessandro Giuseppe Antonio Anastasio
SUBJECT AREA: Electricity[br]b. 18 February 1745 Como, Italyd. 5 March 1827 Como, Italy[br]Italian physicist, discoverer of a source of continuous electric current from a pile of dissimilar metals.[br]Volta had an early command of English, French and Latin, and also learned to read Dutch and Spanish. After completing studies at the Royal Seminary in Como he was involved in the study of physics, chemistry and electricity. He became a teacher of physics in his native town and in 1779 was appointed Professor of Physics at the University of Pavia, a post he held for forty years.With a growing international reputation and a wish to keep abreast of the latest developments, in 1777 he began the first of many travels abroad. A journey started in 1781 to Switzerland, Germany, Belgium, Holland, France and England lasted about one year. By 1791 he had been elected to membership of many learned societies, including those in Zurich, Berlin, Berne and Paris. Volta's invention of his pile resulted from a controversy with Luigi Galvani, Professor of Anatomy at the University of Bologna. Galvani discovered that the muscles of frogs' legs contracted when touched with two pieces of different metals and attributed this to a phenomenon of the animal tissue. Volta showed that the excitation was due to a chemical reaction resulting from the contact of the dissimilar metals when moistened. His pile comprised a column of zinc and silver discs, each pair separated by paper moistened with brine, and provided a source of continuous current from a simple and accessible source. The effectiveness of the pile decreased as the paper dried and Volta devised his crown of cups, which had a longer life. In this, pairs of dissimilar metals were placed in each of a number of cups partly filled with an electrolyte such as brine. Volta first announced the results of his experiments with dissimilar metals in 1800 in a letter to Sir Joseph Banks, President of the Royal Society. This letter, published in the Transactions of the Royal Society, has been regarded as one of the most important documents in the history of science. Large batteries were constructed in a number of laboratories soon after Volta's discoveries became known, leading immediately to a series of developments in electrochemistry and eventually in electromagnetism. Volta himself made little further contribution to science. In recognition of his achievement, at a meeting of the International Electrical Congress in Paris in 1881 it was agreed to name the unit of electrical pressure the "volt".[br]Principal Honours and DistinctionsFRS 1791.

Диаграмма состояния контакта сигнализации AX
Контакт имеет два положения: одно положение - в положении автоматического выключателя ВКЛ. (ON) и ОТКЛ. (OFF); второе положение - в положениях автоматического выключателя СРАБОТАЛ (TRIP).
Рис. LS Industrial SystemsAlarm switches offer provisions for immediate audio or visual indication of a tripped breaker due to overload, short-circuit, operation of shunt trip, or undervoltage trip conditions, operation of push button.
They are particularly useful in automated plants where operators must be signaled about changes in the electrical distribution system.
This switch features a closed contact when the circuit breaker is tripped automatically.
In other words, this switch does not function when the breaker is operated manually.
Its contact is open when the circuit breaker is reset.
[LS Industrial Systems]Контакт сигнализации предназначен для реализации звуковой или световой сигнализации срабатывания автоматического выключателя, произошедшей вследствие перегрузки, короткого замыкания, срабатывания минимального расцепителя напряжения, независимого расцепителя или при нажатии кнопки ПРОВЕРКА.
Такие контакты часто применяют в автоматизированных электроустановках, операторы которых должны контролировать изменения, происходящие в системе распределения электроэнергии.
Данный контакт замыкается только при срабатывании автоматического выключателя.
Другими словами, контакт сигнализации не изменяет своего состояния при ручном включении или отключении автоматического выключателя.
Контакт сигнализации размыкается при переводе автоматического выключателя из положения СРАБОТАЛ в положение ОТКЛЮЧЕН.
