4 Taylor, Frederick Winslow
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 20 March 1856 Germantown, Pennsylvania, USAd. 21 March 1915 Philadelphia, Pennsylvania, USA[br]American mechanical engineer and pioneer of scientific management.[br]Frederick W.Taylor received his early education from his mother, followed by some years of schooling in France and Germany. Then in 1872 he entered Phillips Exeter Academy, New Hampshire, to prepare for Harvard Law School, as it was intended that he should follow his father's profession. However, in 1874 he had to abandon his studies because of poor eyesight, and he began an apprenticeship at a pump-manufacturing works in Philadelphia learning the trades of pattern-maker and machinist. On its completion in 1878 he joined the Midvale Steel Company, at first as a labourer but then as Shop Clerk and Foreman, finally becoming Chief Engineer in 1884. At the same time he was able to resume study in the evenings at the Stevens Institute of Technology, and in 1883 he obtained the degree of Mechanical Engineer (ME). He also found time to take part in amateur sport and in 1881 he won the tennis doubles championship of the United States.It was while with the Midvale Steel Company that Taylor began the systematic study of workshop management, and the application of his techniques produced significant increases in the company's output and productivity. In 1890 he became Manager of a company operating large paper mills in Maine and Wisconsin, until 1893 when he set up on his own account as a consulting engineer specializing in management organization. In 1898 he was retained exclusively by the Bethlehem Steel Company, and there continued his work on the metal-cutting process that he had started at Midvale. In collaboration with J.Maunsel White (1856–1912) he developed high-speed tool steels and their heat treatment which increased cutting capacity by up to 300 per cent. He resigned from the Bethlehem Steel Company in 1901 and devoted the remainder of his life to expounding the principles of scientific management which became known as "Taylorism". The Society to Promote the Science of Management was established in 1911, renamed the Taylor Society after his death. He was an active member of the American Society of Mechanical Engineers and was its President in 1906; his presidential address "On the Art of Cutting Metals" was reprinted in book form.[br]Principal Honours and DistinctionsParis Exposition Gold Medal 1900.

5 Vermuyden, Sir Cornelius
SUBJECT AREA: Civil engineering[br]b. c. 1590 St Maartensdijk, Zeeland, the Netherlandsd. 4 February 1656 probably London, England[br]Dutch/British civil engineer responsible for many of the drainage and flood-protection schemes in low-lying areas of England in the seventeenth century.[br]At the beginning of the seventeenth century, several wealthy men in England joined forces as "adventurers" to put their money into land ventures. One such group was responsible for the draining of the Fens. The first need was to find engineers who were versed in the processes of land drainage, particularly when that land was at, or below, sea level. It was natural, therefore, to turn to the Netherlands to find these skilled men. Joachim Liens was one of the first of the Dutch engineers to go to England, and he started work on the Great Level; however, no real progress was made until 1621, when Cornelius Vermuyden was brought to England to assist in the work.Vermuyden had grown up in a district where he could see for himself the techniques of embanking and reclaiming land from the sea. He acquired a reputation of expertise in this field, and by 1621 his fame had spread to England. In that year the Thames had flooded and breached its banks near Havering and Dagenham in Essex. Vermuyden was commissioned to repair the breach and drain neighbouring marshland, with what he claimed as complete success. The Commissioners of Sewers for Essex disputed this claim and whthheld his fee, but King Charles I granted him a portion of the reclaimed land as compensation.In 1626 Vermuyden carried out his first scheme for drainage works as a consultant. This was the drainage of Hatfield Chase in South Yorkshire. Charles I was, in fact, Vermuyden's employer in the drainage of the Chase, and the work was undertaken as a means of raising additional rents for the Royal Exchequer. Vermuyden was himself an "adventurer" in the undertaking, putting capital into the venture and receiving the title to a considerable proportion of the drained lands. One of the important elements of his drainage designs was the principal of "washes", which were flat areas between the protective dykes and the rivers to carry flood waters, to prevent them spreading on to nearby land. Vermuyden faced bitter opposition from those whose livelihoods depended on the marshlands and who resorted to sabotage of the embankments and violence against his imported Dutch workmen to defend their rights. The work could not be completed until arbiters had ruled out on the respective rights of the parties involved. Disagreements and criticism of his engineering practices continued and he gave up his interest in Hatfield Chase. The Hatfield Chase undertaking was not a great success, although the land is now rich farmland around the river Don in Doncaster. However, the involved financial and land-ownership arrangements were the key to the granting of a knighthood to Cornelius Vermuyden in January 1628, and in 1630 he purchased 4,000 acres of low-lying land on Sedgemoor in Somerset.In 1629 Vermuyden embarked on his most important work, that of draining the Great Level in the fenlands of East Anglia. Francis Russell, 4th Earl of Bedford, was given charge of the work, with Vermuyden as Engineer; in this venture they were speculators and partners and were recompensed by a grant of land. The area which contains the Cambridgeshire tributaries of the Great Ouse were subject to severe and usually annual flooding. The works to contain the rivers in their flood period were important. Whilst the rivers were contained with the enclosed flood plain, the land beyond became highly sought-after because of the quality of the soil. The fourteen "adventurers" who eventually came into partnership with the Earl of Bedford and Vermuyden were the financiers of the scheme and also received land in accordance with their input into the scheme. In 1637 the work was claimed to be complete, but this was disputed, with Vermuyden defending himself against criticism in a pamphlet entitled Discourse Touching the Great Fennes (1638; 1642, London). In fact, much remained to be done, and after an interruption due to the Civil War the scheme was finished in 1652. Whilst the process of the Great Level works had closely involved the King, Oliver Cromwell was equally concerned over the success of the scheme. By 1655 Cornelius Vermuyden had ceased to have anything to do with the Great Level. At that stage he was asked to account for large sums granted to him to expedite the work but was unable to do so; most of his assets were seized to cover the deficiency, and from then on he subsided into obscurity and poverty.While Cornelius Vermuyden, as a Dutchman, was well versed in the drainage needs of his own country, he developed his skills as a hydraulic engineer in England and drained acres of derelict flooded land.[br]Principal Honours and DistinctionsKnighted 1628.Further ReadingL.E.Harris, 1953, Vermuyden and the Fens, London: Cleaver Hume Press.

6 Beau de Rochas, Alphonse Eugène
SUBJECT AREA: Steam and internal combustion engines[br]b. 1815 Franced. 1893 France[br]French railway engineer, patentee of a four-stroke cycle engine.[br]Renowned more for his ideas on technical matters than his practical deeds, Beau de Rochas was a prolific thinker. Within a few years he proposed a rail tunnel beneath the English Channel, a submarine telegraph, a new kind of drive for canal boats, the use of steel for high-pressure boilers and a method of improving the adhesion of locomotive wheels travelling the Alps.The most notable of Beau de Rochas's ideas occurred in 1862 when he was employed as Ingenieur Attaché to the Central de Chemins. With remarkable foresight, he expressed the theoretical considerations for the cycle of operations for the now widely used four-stroke cycle engine. A French patent of 1862 lapsed with a failure to pay the annuity and thus the proposals for a new motive power lapsed into obscurity. Resurrected some twenty years later, the Beau de Rochas tract figures prominently in patent litigation cases. In 1885, a German court upheld a submission by a German patent lawyer that Otto's four-stroke engine of 1876 infringed the Beau de Rochas patent. It remains a mystery why Beau de Rochas never emerged at any time to defend his claims. In France he is regarded as the inventor of the four-stroke cycle engine.[br]Principal Honours and DistinctionsSociété d'Encouragement pour l'Industrie Nationale, prize of 3000 francs, 1891.Bibliography1885, The Engineer 60:441 (an English translation of the Beau de Rochas tract).Further Reading1938, Bulletin de la Société d'Encouragement pour l'Industrie Nationale 137:209–39. 1962, Document pour l'histoire des techniques Cahier no. 2: pp. 3–42.B.Donkin, 1900, The Gas, Oil and Air Engine, London: p. 467.See also: Langen, EugenKABBiographical history of technology > Beau de Rochas, Alphonse Eugène

7 Blumlein, Alan Dower
SUBJECT AREA: Aerospace, Broadcasting, Electronics and information technology, Photography, film and optics, Recording, Telecommunications[br]b. 29 June 1903 Hampstead, London, Englandd. 7 June 1942[br]English electronics engineer, developer of telephone equipment, highly linear electromechanical recording and reproduction equipment, stereo techniques, video and radar technology.[br]He was a very bright scholar and received a BSc in electrical technology from City and Guilds College in 1923. He joined International Western Electric (later to become Standard Telephone and Cables) in 1924 after a period as an instructor/demonstrator at City and Guilds. He was instrumental in the design of telephone measuring equipment and in international committee work for standards for long-distance telephony.From 1929 Blumlein was employed by the Columbia Graphophone Company to develop an electric recording cutterhead that would be independent of Western Electric's patents for the system developed by Maxfield and Harrison. He attacked the problems in a most systematic fashion, and within a year he had developed a moving-coil cutterhead that was much more linear than the iron-cored systems known at the time. Eventually Blumlein designed a complete line of recording equipment, from microphone and through-power amplifiers. The design was used by Columbia; after the merger with the Gramophone Company in 1931 to form Electrical and Musical Industries Ltd (later known as EMI) it became the company standard, certainly for coarse-groove records, until c.1950.Blumlein became interested in stereophony (binaural sound), and developed and demonstrated a complete line of equipment, from correctly placed microphones via two-channel records and stereo pick-ups to correctly placed loudspeakers. The advent of silent surfaces of vinyl records made this approach commercial from the late 1950s. His approach was independent and quite different from that of A.C. Keller.His extreme facility for creating innovative solutions to electronic problems was used in EMI's development from 1934 to 1938 of the electronic television system, which became the BBC standard of 405 lines after the Second World War, when television broadcasting again became possible. Independent of official requirements, EMI developed a 60 MHz radar system and Blumlein was involved in the development of a centimetric radar and display system. It was during testing of this aircraft mounted equipment that he was killed in a crash.[br]BibliographyBlumlein was inventor or co-inventor of well over 120 patents, a complete list of which is to be found in Burns (1992; see below). The major sound-recording achievements are documented by British patent nos. 350,954, 350,998, 363,627 (highly linear cutterhead, 1930) and 394,325 (reads like a textbook on stereo technology, 1931).Further ReadingThe definitive biography of Blumlein has not yet been written; the material seems to have been collected, but is not yet available. However, R.W.Burns, 1992, "A.D.Blumlein, engineer extraordinary", Engineering Science and Education Journal (February): 19– 33 is a thorough account. Also B.J.Benzimra, 1967, "A.D. Blumlein: an electronics genius", Electronics \& Power (June): 218–24 provides an interesting summary.GB-N -
8 Colpitts, Edwin Henry
[br]b. 9 January 1872 Pointe de Bute, Canadad. 6 March 1949 Orange, New Jersey, USA[br]Canadian physicist and electrical engineer responsible for important developments in electronic-circuit technology.[br]Colpitts obtained Bachelor's degrees at Mount Allison University, Sackville, New Brunswick, and Harvard in 1894 and 1896, respectively, followed by a Master's degree at Harvard in 1897. After two years as assistant to the professor of physics there, he joined the American Bell Telephone Company. When the Bell Company was reorganized in 1907, he moved to the Western Electric branch of the company in New York as Head of the Physical Laboratories. In 1911 he became a director of the Research Laboratories, and in 1917 he became Assistant Chief Engineer of the company. During this time he invented both the push-pull amplifier and the Colpitts oscillator, both major developments in communications. In 1917, during the First World War, he spent some time in France helping to set up the US Signal Corps Research Laboratories. Afterwards he continued to do much, both technically and as a manager, to place telephone communications on a firm scientific basis, retiring as Vice-President of the Bell Telephone Laboratories in 1937. With the outbreak of the Second World War in 1941 he was recalled from retirement and appointed Director of the Engineering Foundation to work on submarine warfare techniques, particularly echo-ranging.[br]Principal Honours and DistinctionsOrder of the Rising Sun, Japan, 1938.

9 Cotchett, Thomas
SUBJECT AREA: Textiles[br]fl. 1700s[br]English engineer who set up the first water-powered textile mill in Britain at Derby.[br]At the beginning of the eighteenth century, silk weaving was one of the most prosperous trades in Britain, but it depended upon raw silk worked up on hand twisting or throwing machines. In 1702 Thomas Cotchett set up a mill for twisting silk by water-power at the northern end of an island in the river Derwent at Derby; this would probably have been to produce organzine, the hard twisted thread used for the warp when weaving silk fabrics. Such mills had been established in Italy beginning with the earliest in Bologna in 1272, but it would appear that Cotchett used Dutch silk-throwing machinery that was driven by a water wheel that was 13½ ft (4.1 m) in diameter and built by the local engineer, George Sorocold. The enterprise soon failed, but it was quickly revived and extended by Thomas and John Lombe with machinery based on that being used successfully in Italy.[br]Further ReadingD.M.Smith, 1965, Industrial Archaeology of the East Midlands, Newton Abbot (provides an account of Cotchett's mill).W.H.Chaloner, 1963, "Sir Thomas Lombe (1685–1739) and the British silk industry", History Today (Nov.).R.L.Hills, 1970, Power in the Industrial Revolution, Manchester (a brief coverage of the development of early silk throwing mills).D.Kuhn, 1988, Science and Civilisation in China, Vol. V: Chemistry and ChemicalTechnology, Part 9, Textile Technology: spinning and reeling, Cambridge (covers the diffusion of the techniques of the mechanization of the silk-throwing industry from China to the West).RLH -
10 Freyssinet, Eugène
[br]b. 13 July 1879 Objat, Corrèze, Franced. 8 June 1962 Saint-Martin Vésubié, France[br]French civil engineer who is generally recognized as the originator of pre-stressed reinforced concrete.[br]Eugène Freyssinet was an army engineer during the First World War who pioneered pre-stressed reinforced concrete and experimented with building concrete bridges. After 1918 he formed his own company to develop his ideas. He investigated the possibilities of very high-strength concrete, and in so doing studied shrinkage and creep. He combined high-quality concrete with highly stressed, stretched steel to give top quality results. His work in 1926 on Plougastel Bridge, at that time the longest reinforced concrete bridge, is a notable example of his use of this technique. In 1916 Freyssinet had built his famous airship hangars at Orly, which were destroyed in the Second World War; the hangars were roofed in parabolic sections to a height of about 200 ft. In 1934 he succeeded in saving the Ocean Terminal at Le Havre from sinking into the mud and being covered by the sea by using his pre-stressing techniques. By 1938 he had developed a superior method of pre-stressing with steel which led to widespread adoption of his methods.[br]Further ReadingC.C.Stanley, 1979, Highlights in the History of Concrete, Cement and Concrete Association.1977, Who's Who in Architecture, Weidenfeld and Nicolson.DY -
11 Kirk, Alexander Carnegie
[br]b. c.1830 Barry, Angus, Scotlandd. 5 October 1892 Glasgow, Scotland[br]Scottish marine engineer, advocate of multiple-expansion in steam reciprocating engines.[br]Kirk was a son of the manse, and after attending school at Arbroath he proceeded to Edinburgh University. Following graduation he served an apprenticeship at the Vulcan Foundry, Glasgow, before serving first as Chief Draughtsman with the Thames shipbuilders and engineers Maudslay Sons \& Field, and later as Engineer of Paraffin Young's Works at Bathgate and West Calder in Lothian. He was credited with the inventions of many ingenious appliances and techniques for improving production in these two establishments. About 1866 Kirk returned to Glasgow as Manager of the Cranstonhill Engine Works, then moved to Elder's Shipyard (later known as the Fairfield Company) as Engineering Manager. There he made history in producing the world's first triple-expansion engines for the single-screw steamship Propontis in 1874. That decade was to confirm the Clyde's leading role as shipbuilders to the world and to establish the iron ship with efficient reciprocating machinery as the workhorse of the British Merchant Marine. Upon the death of the great Clyde shipbuilder Robert Napier in 1876, Kirk and others took over as partners in the shipbuilding yard and engine shops of Robert Napier \& Sons. There in 1881 they built a ship that is acknowledged as one of the masterpieces of British shipbuilding: the SS Aberdeen for George Thompson's Aberdeen Line to the Far East. In this ship the fullest advantage was taken of high steam temperatures and pressures, which were expanded progressively in a three-cylinder configuration. The Aberdeen, in its many voyages from London to China and Japan, was to prove the efficiency of these engines that had been so carefully designed in Glasgow. In the following years Dr Kirk (he has always been known as Doctor, although his honorary LLD was only awarded by Glasgow University in 1888) persuaded the Admiralty and several shipping companies to accept not only triple-expansion machinery but also the use of mild steel in ship construction. The successful SS Parisian, built for the Allan Line of Glasgow, was one of these pioneer ships.[br]Principal Honours and DistinctionsFellow of the Royal Society of Edinburgh.FMWBiographical history of technology > Kirk, Alexander Carnegie

12 Millington, John
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 1779d. 1868[br]English engineer and educator.[br]John Millington was Professor of Mechanics at the Royal Institution, London, from 1817 to 1829. He gave numerous courses on natural philosophy and mechanics and supported the introduction of coal gas for lighting. In 1823 he testified to a Select Committee of the House of Commons that the spread of gas lighting would greatly benefit the preservation of law and order, and with the same utilitarian and penal inclination he devised a treadmill for use in the Bedfordshire House of Correction. Millington was appointed the first Professor of Engineering and the Application of Mechanical Philosophy to the Arts at the newly founded University of London in 1828, but he speedily resigned from the post, preferring to go to Mexico in 1829. Like Trevithick and Robert Stephenson before him, he was attracted to the New World by the possibility of using new techniques to reopen old mines, and he became an engineer to some Mexican mining projects. In 1837 he went to Williamsburg in the United States, being appointed Professor of Chemistry, and it was there that he died in 1868. Millington wrote extensively on scientific subjects.[br]Further ReadingDictionary of National Biography.M.Berman, The Royal Institution, pp. 46, 98–9.AB -
13 Murray, Matthew
SUBJECT AREA: Land transport, Mechanical, pneumatic and hydraulic engineering, Railways and locomotives, Steam and internal combustion engines[br]b. 1765 near Newcastle upon Tyne, Englandd. 20 February 1826 Holbeck, Leeds, England[br]English mechanical engineer and steam engine, locomotive and machine-tool pioneer.[br]Matthew Murray was apprenticed at the age of 14 to a blacksmith who probably also did millwrighting work. He then worked as a journeyman mechanic at Stockton-on-Tees, where he had experience with machinery for a flax mill at Darlington. Trade in the Stockton area became slack in 1788 and Murray sought work in Leeds, where he was employed by John Marshall, who owned a flax mill at Adel, located about 5 miles (8 km) from Leeds. He soon became Marshall's chief mechanic, and when in 1790 a new mill was built in the Holbeck district of Leeds by Marshall and his partner Benyon, Murray was responsible for the installation of the machinery. At about this time he took out two patents relating to improvements in textile machinery.In 1795 he left Marshall's employment and, in partnership with David Wood (1761– 1820), established a general engineering and millwrighting business at Mill Green, Holbeck. In the following year the firm moved to a larger site at Water Lane, Holbeck, and additional capital was provided by two new partners, James Fenton (1754–1834) and William Lister (1796–1811). Lister was a sleeping partner and the firm was known as Fenton, Murray \& Wood and was organized so that Fenton kept the accounts, Wood was the administrator and took charge of the workshops, while Murray provided the technical expertise. The factory was extended in 1802 by the construction of a fitting shop of circular form, after which the establishment became known as the "Round Foundry".In addition to textile machinery, the firm soon began the manufacture of machine tools and steam-engines. In this field it became a serious rival to Boulton \& Watt, who privately acknowledged Murray's superior craftsmanship, particularly in foundry work, and resorted to some industrial espionage to discover details of his techniques. Murray obtained patents for improvements in steam engines in 1799, 1801 and 1802. These included automatic regulation of draught, a mechanical stoker and his short-D slide valve. The patent of 1801 was successfully opposed by Boulton \& Watt. An important contribution of Murray to the development of the steam engine was the use of a bedplate so that the engine became a compact, self-contained unit instead of separate components built into an en-gine-house.Murray was one of the first, if not the very first, to build machine tools for sale. However, this was not the case with the planing machine, which he is said to have invented to produce flat surfaces for his slide valves. Rather than being patented, this machine was kept secret, although it was apparently in use before 1814.In 1812 Murray was engaged by John Blenkinsop (1783–1831) to build locomotives for his rack railway from Middleton Colliery to Leeds (about 3 1/2 miles or 5.6 km). Murray was responsible for their design and they were fitted with two double-acting cylinders and cranks at right angles, an important step in the development of the steam locomotive. About six of these locomotives were built for the Middleton and other colliery railways and some were in use for over twenty years. Murray also supplied engines for many early steamboats. In addition, he built some hydraulic machinery and in 1814 patented a hydraulic press for baling cloth.Murray's son-in-law, Richard Jackson, later became a partner in the firm, which was then styled Fenton, Murray \& Jackson. The firm went out of business in 1843.[br]Principal Honours and DistinctionsSociety of Arts Gold Medal 1809 (for machine for hackling flax).Further ReadingL.T.C.Rolt, 1962, Great Engineers, London (contains a good short biography).E.Kilburn Scott (ed.), 1928, Matthew Murray, Pioneer Engineer, Leeds (a collection of essays and source material).C.F.Dendy Marshall, 1953, A History of Railway Locomotives Down to the End of theYear 1831, London.L.T.C.Rolt, 1965, Tools for the Job, London; repub. 1986 (provides information on Murray's machine-tool work).Some of Murray's correspondence with Simon Goodrich of the Admiralty has been published in Transactions of the Newcomen Society 3 (1922–3); 6(1925–6); 18(1937– 8); and 32 (1959–60).RTS -
14 Sommeiller, Germain
[br]b. 15 March 1815 St Jeoire, Haute-Savoie, Franced. 11 July 1874 St Jeoire, Haute-Savoie, France[br]French civil engineer, builder of the Mont Cénis tunnel in the Alps.[br]Having been employed in railway construction in Sardinia, Sommeiller was working as an engineer at the University of Turin when, in 1857, he was commissioned to take charge of the French part in the construction of the 13 km (8 mile) tunnel under Mont Cénis between Modane, France, and Bardonècchia, Italy. This was to be the first long-distance tunnel through rock in the Alps driven from two headings with no intervening shafts; it is a landmark in the history of technology thanks to the use of a number of pioneering techniques in its construction.As steam power was unsuitable because of the difficulties in transmitting power over long distances, Sommeiller developed ideas for the use of compressed-air machinery, first mooted by Daniel Colladon of Geneva in 1855; this also solved the problems of ventilation. He also decided to adapt the principle of his compressed-air ram to supply extra power to locomotives on steep gradients. In 1860 he took out a patent in France for a combined compressor-pump, and in 1861 his first percussion drill, mounted on a carriage, was introduced. Although it was of little use at first, Sommeiller improved his drill through trial and error, including the use of the diamond drill-crowns patented by Georges Auguste Leschot in 1862.

16 Keller, Arthur
[br]b. 18 August 1901 New York City, New York, USA d. 1983[br]American engineer and developer of telephone switching equipment who was instrumental in the development of electromechanical recording and stereo techniques.[br]He obtained a BSc in electrical engineering at Cooper Union for the Advancement of Science and Art, New York, in 1923 and an MSc from Yale University, and he did postgraduate work at Columbia University. Most of the time he was also on the staff of the Bell Telephone Laboratories. The Bell Laboratories and its predecessors had a long tradition in research in speech and hearing, and in a team of researchers under H.C. Harrison, Keller developed a number of definite improvements in electrical pick-ups, gold-sputtering for matrix work and electrical disc recording equipment. From 1931 onwards the team at Bell Labs developed disc recording for moving pictures and entered into collaboration with Leopold Stokowski and the Philadelphia Orchestra concerning transmission and recording of high-fidelity sound over wires, and stereo techniques. Keller developed a stereo recording system for disc records independently of A.D. Blumlein that was used experimentally in the Bell Labs during the 1930s. During the Second World War Keller was in a team developing sonar (sound navigation and ranging) for the US Navy. After the war he concentrated on switching equipment for telephone exchanges and developed a miniature relay. In 1966 he retired from the Bell Laboratories, where he had been Director of several departments, ending as Director of the Switching Apparatus Laboratory. After retirement he was a consultant internationally, concerning electromechanical devices in particular. When, in 1980, the Bell Laboratories decided to issue LP re-recordings of a number of the experimental records made during the 1930s, Keller was brought in from retirement to supervise the project and decide on the selections.[br]BibliographyKeller was inventor or co-inventor of forty patents, including: US patent no. 2,114,471 (the principles of stereo disc recording); US patent no. 2,612,586 (tape guides with air lubrication); US patent no. 3,366,901 (a miniature crossbar switch).Apart from a large number of highly technical papers, Keller also wrote the article "Phonograph" in the 1950 and 1957 editions of Encyclopaedia Britannica.1986, Reflections of a Stereo Pioneer, San Francisco: San Francisco Press (an honest, personal account).GB-N -

A LEVELS Al terminar la educación secundaria obligatoria, los estudiantes de Inglaterra, Gales e Irlanda del Norte pueden estudiar otros dos años para preparar tres o cuatro asignaturas más y examinarse de ellas a los 18 años. Estos exámenes se conocen con el nombre de A levels o Advanced levels. Cada universidad determina el número de A levels y la calificación necesaria para acceder a ella. En Escocia los exámenes equivalentes son los Highers o Higher Grades, que se hacen de unas cinco asignaturas tras un año de estudios. Después se puede optar entre entrar en la universidad directamente o estudiar otro año más, bien para hacer el mismo examen de otras asignaturas, o para sacar los Advanced Highers.A to Z ® N — (=map book) callejero m
