101 Shortt, William Hamilton
SUBJECT AREA: Horology[br]b. 28 September 1881d. 4 February 1971[br]British railway engineer and amateur horologist who designed the first successful free-pendulum clock.[br]Shortt entered the Engineering Department of the London and South Western Railway as an engineering cadet in 1902, remaining with the company and its successors until he retired in 1946. He became interested in precision horology in 1908, when he designed an instrument for recording the speed of trains; this led to a long and fruitful collaboration with Frank HopeJones, the proprietor of the Synchronome Company. This association culminated in the installation of a free-pendulum clock, with an accuracy of the order of one second per year, at Edinburgh Observatory in 1921. The clock's performance was far better than that of existing clocks, such as the Riefler, and a slightly modified version was produced commercially by the Synchronome Company. These clocks provided the time standard at Greenwich and many other observatories and scientific institutions across the world until they were supplanted by the quartz clock.The period of a pendulum is constant if it swings freely with a constant amplitude in a vacuum. However, this ideal state cannot be achieved in a clock because the pendulum must be impulsed to maintain its amplitude and the swings have to be counted to indicate time. The free-pendulum clock is an attempt to approach this ideal as closely as possible. In 1898 R.J. Rudd used a slave clock, synchronized with a free pendulum, to time the impulses delivered to the free pendulum. This clock was not successful, but it provided the inspiration for Shortt's clock, which operates on the same principle. The Shortt clock used a standard Synchronome electric clock as the slave, and its pendulum was kept in step with the free pendulum by means of the "hit and miss" synchronizer that Shortt had patented in 1921. This allowed the pendulum to swing freely (in a vacuum), apart from the fraction of a second in which it received an impulse each half-minute.[br]Principal Honours and DistinctionsMaster of the Clockmakers' Company 1950.

104 Holmes, Frederic Hale
[br]fl. 1850s–60s[br]British engineer who pioneered the electrical illumination of lighthouses in Great Britain.[br]An important application of the magneto generator was demonstrated by Holmes in 1853 when he showed that it might be used to supply an arc lamp. This had many implications for the future because it presented the possibility of making electric lighting economically successful. In 1856 he patented a machine with six disc armatures on a common axis rotating between seven banks of permanent magnets. The following year Holmes suggested the possible application of his invention to lighthouse illumination and a trial was arranged and observed by Faraday, who was at that time scientific adviser to Trinity House, the corporation entrusted with the care of light-houses in England and Wales. Although the trial was successful and gained the approval of Faraday, the Elder Brethren of Trinity House imposed strict conditions on Holmes's design for machines to be used for a more extensive trial. These included connecting the machine directly to a slow-speed steam engine, but this resulted in a reduced performance. The experiments of Holmes and Faraday were brought to the attention of the French lighthouse authorities and magneto generators manufactured by Société Alliance began to be installed in some lighthouses along the coast of France. After noticing the French commutatorless machines, Holmes produced an alternator of similar type in 1867. Two of these were constructed for a new lighthouse at Souter Point near Newcastle and two were installed in each of the two lighthouses at South Foreland. One of the machines from South Foreland that was in service from 1872 to 1922 is preserved in the Royal Museum of Scotland, Edinburgh. A Holmes generator is also preserved in the Science Museum, London. Holmes obtained a series of patents for generators between 1856 and 1869, with all but the last being of the magneto-electric type.[br]Bibliography7 March 1856, British patent no. 573 (the original patent for Holmes's invention).1863, "On magneto electricity and its application to lighthouse purposes", Journal of the Society of Arts 12:39–43.Further ReadingW.J.King, 1962, in The Development of Electrical Technology in the 19th Century; Washington, DC: Smithsonian Institution, Paper 30, pp. 351–63 (provides a detailed account of Holmes's generators).J.N.Douglas, 1879, "The electric light applied to lighthouse illumination", Proceedings of the Institution of Civil Engineers 57(3):77–110 (describes trials of Holmes's machines).GW -
105 Scheutz, George
SUBJECT AREA: Electronics and information technology[br]b. 23 September 1785 Jonkoping, Swedend. 27 May 1873 Stockholm, Sweden[br]Swedish lawyer, journalist and self-taught engineer who, with his son Edvard Raphael Scheutz (b. 13 September 1821 Stockholm, Sweden; d. 28 January 1881 Stockholm, Sweden) constructed a version of the Babbage Difference Engine.[br]After early education at the Jonkoping elementary school and the Weixo Gymnasium, George Scheutz entered the University of Lund, gaining a degree in law in 1805. Following five years' legal work, he moved to Stockholm in 1811 to work at the Supreme Court and, in 1814, as a military auditor. In 1816, he resigned, bought a printing business and became editor of a succession of industrial and technical journals, during which time he made inventions relating to the press. It was in 1830 that he learned from the Edinburgh Review of Babbage's ideas for a difference engine and started to make one from wood, pasteboard and wire. In 1837 his 15-yearold student son, Edvard Raphael Scheutz, offered to make it in metal, and by 1840 they had a working machine with two five-digit registers, which they increased the following year and then added a printer. Obtaining a government grant in 1851, by 1853 they had a fully working machine, now known as Swedish Difference Engine No. 1, which with an experienced operator could generate 120 lines of tables per hour and was used to calculate the logarithms of the numbers 1 to 10,000 in under eighty hours. This was exhibited in London and then at the Paris Great Exhibition, where it won the Gold Medal. It was subsequently sold to the Dudley Observatory in Albany, New York, for US$5,000 and is now in a Chicago museum.In England, the British Registrar-General, wishing to produce new tables for insurance companies, and supported by the Astronomer Royal, arranged for government finance for construction of a second machine (Swedish Difference Engine No. 2). Comprising over 1,000 working parts and weighing 1,000 lb (450 kg), this machine was used to calculate over 600 tables. It is now in the Science Museum.[br]Principal Honours and DistinctionsMember of the Swedish Academy of Sciences, Paris Exhibition Medal of Honour (jointly with Edvard) 1856.

106 Tossach, William
SUBJECT AREA: Medical technology[br]b. c. 1700 probably Perthshire, Scotlandd. after 1771 Alloa, Scotland[br]Scottish surgeon, the first to report a case of artificial respiration by mouth.[br]Little is known of Tossach (a Tossach matriculated at Glasgow University in 1727), but in 1771 he published an account of the resuscitation of a miner, James Blair, who had been rescued from a coal-mine fire. Tossach found "there was not the least pulse in either heart or arteries and not the least breathing could be observed; so that he was in all appearance dead, I applied my mouth close to his, and blowed my breath as strong as I could: but having neglected to close his nostrils all the air came out of them: Wherefore taking hold of them with one hand and holding my other on his breast at the left pap I blew again my breath as strong as I could, raising his chest fully with it; and immediately I felt six or seven very quick beats of the heart." Blair recovered consciousness in an hour and walked home within four.[br]Bibliography1771, "A man dead in appearance recovered by distending the lungs with air", Medical Essays and Observations, Edinburgh.Further Reading1794, Transactions of the Royal Humane Society from 1774–1784, London.

109 Nervi, Pier Luigi
[br]b. 21 June 1891 Sondrio, Italyd. 9 January 1979 (?), Italy[br]Italian engineer who played a vital role in the use and adaptation of reinforced concrete as a structural material from the 1930s to the 1970s.[br]Nervi early established a reputation in the use of reinforced concrete with his stadium in Florence (1930–2). This elegant concrete structure combines graceful curves with functional solidity and is capable of seating some 35,000 spectators. The stadium was followed by the aircraft hangars built for the Italian Air Force at Orvieto and Ortebello, in which he spanned the vast roofs of the hangars with thin-shelled vaults supported by precast concrete beams and steel-reinforced ribs. The structural strength and subtle curves of these ribbed roofs set the pattern for Nervi's techniques, which he subsequently varied and elaborated on to solve problems that arose in further commissions.Immediately after the Second World War Italy was short of supplies of steel for structural purposes so, in contrast to the USA, Britain and Germany, did not for some years construct any quantity of steel-framed rectangular buildinngs used for offices, housing or industrial use. It was Nervi who led the way to a ferroconcrete approach, using a new type of structure based on these materials in the form of a fine steel mesh sprayed with cement mortar and used to roof all kinds of structures. It was a method that resulted in expressionist curves instead of rectangular blocks, and the first of his great exhibition halls at Turin (1949), with a vault span of 240 ft (73 m), was an early example of this technique. Nervi continued to create original and beautiful ferroconcrete structures of infinite variety: for example, the hall at the Lido di Roma, Ostia; the terme at Chianciano; and the three buildings that he designed for the Rome Olympics in 1960. The Palazzetto dello Sport is probably the most famous of these, for which he co-operated with the architect Annibale Vitellozzi to construct a small sports palace seating 5,000 spectators under a concrete "big top" of 194 ft (59 m) diameter, its enclosing walls supported by thirtysix guy ropes of concrete; inside, the elegant roof displays a floral quality. In 1960 Nervi returned to Turin to build his imaginative Palace of Labour for the centenary celebrations of Garibaldi and Victor Emmanuel in the city. This vast hall, like the Crystal Palace in England a century earlier (see Paxton), had to be built quickly and be suitable for later adaptation. It was therefore constructed partly in steel, and the metal supporting columns rose to palm-leaf capitals reminiscent of those in ancient Nile palaces.Nervi's aim was always to create functional buildings that simultaneously act by their aesthetic qualities as an effective educational influence. Functionalism for Nervi never became "brutalism". In consequence, his work is admired by the lay public as well as by architects. He collaborated with many of the outstanding architects of the day: with Gio Ponti on the Pirelli Building in Milan (1955–9); with Zehrfuss and Breuer on the Y-plan UNESCO Building in Paris (1953–7); and with Marcello Piacentini on the 16,000-seat Palazzo dello Sport in Rome. Nervi found time to write a number of books on building construction and design, lectured in the Universities of Rio de Janiero and Buenos Aires, and was for many years Professor of Technology and Technique of Construction in the Faculty of Architecture at the University of Rome.
