101 Crookes, Sir William
SUBJECT AREA: Electricity[br]b. 17 June 1832 London, Englandd. 4 April 1919 London, England[br]English chemist and physicist who carried out studies of electrical discharges and cathode rays in rarefied gases, leading to the development of the cathode ray tube; discoverer of the element thallium and the principle of the Crookes radiometer.[br]Crookes entered the Royal College of Chemistry at the age of 15, and from 1850 to 1854 held the appointment of Assistant at the college. In 1854 he became Superintendent of the Meteorological Department at the Radcliffe Observatory in Oxford. He moved to a post at the College of Science in Chester the following year. Soon after this he inherited a large fortune and set up his own private laboratory in London. There he studied the nature of electrical discharges in gases at low pressure and discovered the dark space (later named after him) that surrounds the negative electrode, or cathode. He also established that the rays produced in the process (subsequently shown by J.J.Thompson to be a stream of electrons) not only travelled in straight lines, but were also capable of producing heat and/or light upon impact with suitable anode materials. Using a variety of new methods to investigate these "cathode" rays, he applied them to the spectral analysis of compounds of selenium and, as a result, in 1861 he discovered the element thallium, finally establishing its atomic weight in 1873. Following his discovery of thallium, he became involved in two main lines of research: the properties of rarified gases, and the investigation of the elements of the "rare earths". It was also during these experiments that he discovered the principle of the Crookes radiometer, a device in which light is converted into rotational motion and which used to be found frequently in the shop windows of English opticians. Also among the fruits of this work were the Crookes tubes and the development of spectacle lenses with differential ranges of radiational absorption. In the 1870s he became interested in spiritualism and acquired a reputation for his studies of psychic phenomena, but at the turn of the century he returned to traditional scientific investigations. In 1892 he wrote about the possibility of wireless telegraphy. His work in the field of radioactivity led to the invention of the spinthariscope, an early type of detector of alpha particles. In 1900 he undertook investigations into uranium which led to the study of scintillation, an important tool in the study of radioactivity.While the theoretical basis of his work has not stood the test of time, his material discoveries, observations and investigations of new facts formed a basis on which others such as J.J. Thomson were to develop subatomic theory. His later involvement in the investigation of spiritualism led to much criticism, but could be justified on the basis of a belief in the duty to investigate all phenomena.[br]Principal Honours and DistinctionsKnighted 1897.

102 Ingersoll, Simon
SUBJECT AREA: Mining and extraction technology[br]b. 3 March 1818 Stamford, Connecticut, USAd. 24 July 1894 Stamford, Connecticut, USA[br]American mechanic, inventor of a rock drill[br]Ingersoll worked on his father's farm and spent much of his time carrying out all kinds of mechanical experiments until 1839, when he went to Long Island, New York, to work on another farm. Having returned home in 1858, he received several patents for different mechanical devices, but he did not know how to turn his inventive talent into economic profit. His patents were sold to others for money to continue his work and support his family. In 1870, working again on Long Island, he by chance came into contact with New York City's largest contractor, who urged him to design a mechanical rock drill in order to replace hand drills in the rock-excavation business. Within one year Ingersoll built several models and a full-size machine at the machine shop of Henry Clark Sergeant, who contributed several improvements. They secured a joint patent in 1871, which was soon followed by a patent for a rock drill with tappet-valve motion.Although the Ingersoll Drill Company was established, he again sold the patent rights and went back to Stamford, where he continued his inventive work and gained several more patents for improving the rock drill. However, he never understood how to make a fortune from his patents, and he died almost penniless. His former partner, Sergeant, who had formed his own drill company on the basis of an entirely novel valve motion which led to compressed air being used as a power source, in 1888 established the Ingersoll- Sergeant Drill Company, which in 1905 merged with Rand Drill Company, which had been a competitor, to form the Ingersoll-Rand Company. This merger led to many achievements in manufacturing rock drills and air compressors at a time when there was growing demand for such machinery.[br]Further ReadingDictionary of American Biography (articles on both Ingersoll and Sergeant).

103 Kennedy, John
SUBJECT AREA: Textiles[br]b. 4 July 1769 Knocknalling, Kirkcudbrightshire, Scotlandd. 30 October 1855 Ardwick Hall, Manchester, England[br]Scottish cotton spinner and textile machine maker.[br]Kennedy was the third son of his father, Robert, and went to the village school in Dalry. On his father's death, he was sent at the age of 14 to Chowbent, Lancashire, where he was apprenticed to William Cannan, a maker of textile machines such as carding frames, Hargreaves's jennies and Arkwright's waterframes. On completion of his apprenticeship in 1791, he moved to Manchester and entered into partnership with Benjamin and William Sandford and James M'Connel, textile machine makers and mule spinners. In 1795 this partnership was terminated and one was made with James M'Connel to form the firm M'Connel \& Kennedy, cotton spinners.Kennedy introduced improvements for spinning fine yarns and the firm of M'Connel \& Kennedy became famous for the quality of these products, which were in great demand. He made the spindles turn faster during the second part of the mule carriage's outward draw, and from 1793 onwards he experimented with driving mules by steam engines. Like William Kelly at New Lanark, he succeeded in making the spinning sequences power-operated by 1800, although the spinner had to take over the winding on. This made the mule into a factory machine, but it still required skilled operators. He was also involved with Henry Houldsworth, Junior, in the improvement of the roving frame. In 1803 Kennedy joined the Manchester Literary \& Philosophical Society, to which he presented several papers, including one in 1830 on "A memoir of Samuel Crompton". He retired from the spinning business in 1826, but continued his technical and mechanical pursuits. He was consulted about whether the Liverpool \& Manchester Railway should have moving or stationary steam engines and was an umpire at the Rainhill Trials in 1829.[br]Further ReadingDictionary of National Biography.W.Fairbairn, obituary, Manchester Memoirs, Manchester Literary and Philosophical Society.C.H.Lee, 1972, A Cotton Enterprise 1795–1840.

104 Meikle, Andrew
SUBJECT AREA: Agricultural and food technology[br]b. 1719 Scotlandd. 27 November 1811[br]Scottish millwright and inventor of the threshing machine.[br]The son of the millwright James Meikle, who is credited with the introduction of the winnowing machine into Britain, Andrew Meikle followed in his father's footsteps. His inventive inclinations were first turned to developing his father's idea, and together with his own son George he built and patented a double-fan winnowing machine.However, in the history of agricultural development Andrew Meikle is most famous for his invention of the threshing machine, patented in 1784. He had been presented with a model of a threshing mill designed by a Mr Ilderton of Northumberland, but after failing to make a full-scale machine work, he developed the concept further. He eventually built the first working threshing machine for a farmer called Stein at Kilbagio. The patent revolutionized farming practice because it displaced the back-breaking and soul-destroying labour of flailing the grain from the straw. The invention was of great value in Scotland and in northern England when the land was becoming underpopulated as a result of heavy industrialization, but it was bitterly opposed in the south of England until well into the nineteenth century. Although the introduction of the threshing machine led to the "Captain Swing" riots of the 1830s, in opposition to it, it shortly became universal.Meikle's provisional patent in 1785 was a natural progression of earlier attempts by other millwrights to produce such a machine. The published patent is based on power provided by a horse engine, but these threshing machines were often driven by water-wheels or even by windmills. The corn stalks were introduced into the machine where they were fed between cast-iron rollers moving quite fast against each other to beat the grain out of the ears. The power source, whether animal, water or wind, had to cause the rollers to rotate at high speed to knock the grain out of the ears. While Meikle's machine was at first designed as a fixed barn machine powered by a water-wheel or by a horse wheel, later threshing machines became mobile and were part of the rig of an agricultural contractor.In 1788 Meikle was awarded a patent for the invention of shuttered sails for windmills. This patent is part of the general description of the threshing machine, and whilst it was a practical application, it was superseded by the work of Thomas Cubitt.At the turn of the century Meikle became a manufacturer of threshing machines, building appliances that combined the threshing and winnowing principles as well as the reciprocating "straw walkers" found in subsequent threshing machines and in conventional combine harvesters to the present day. However, he made little financial gain from his invention, and a public subscription organized by the President of the Board of Agriculture, Sir John Sinclair, raised £1,500 to support him towards the end of his life.[br]Bibliography1831, Threshing Machines in The Dictionary of Mechanical Sciences, Arts and Manufactures, London: Jamieson, Alexander.7 March 1768, British patent no. 896, "Machine for dressing wheat, malt and other grain and for cleaning them from sand, dust and smut".9 April 1788, British patent no. 1,645, "Machine which may be worked by cattle, wind, water or other power for the purpose of separating corn from the straw".Further ReadingJ.E.Handley, 1953, Scottish Farming in the 18th Century, and 1963, The Agricultural Revolution in Scotland (both place Meikle and his invention within their context).G.Quick and W.Buchele, 1978, The Grain Harvesters, American Society of Agricultural Engineers (gives an account of the early development of harvesting and cereal treatment machinery).KM / AP -
105 Reynolds, Osborne
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 23 April 1842 Belfast, Irelandd. 1912 Watchet, Somerset, England[br]English engineer and educator.[br]Osborne Reynolds's father, a clergyman and schoolteacher, had been a Fellow of Queens' College, Cambridge; it was to Queens' that the young Reynolds went to study mathematics, graduating as 7th Wrangler in 1867, and going on in his turn to become a Fellow of the College. Reynolds had developed an interest in practical applications of physics and engineering, and for a short time he entered the office of the London civil engineers Lawson and Mansergh. In 1868 he was appointed to the new Chair of Engineering at Owens College, Manchester, and he remained in this post for thirty-seven years, until he retired in 1905. During this period he presided over a department that grew steadily in size and reputation, and undertook prolonged research projects into phenomena such as lubrication, the laws governing the flow of water in pipes, turbulence and other physical features with practical applications. He was elected a Fellow of the Royal Society in 1877, being nominated Royal Medallist in 1888. In 1883 he became a Member of the Institution of Civil Engineers, and in 1885 he was awarded the Telford Premium of the Institution. He served as Secretary of the Manchester Literary and Philosophical Society from 1874 to 1883, and was appointed President in 1888–9 and Dalton Medallist in 1903. He was President of Section G of the British Association for the History of Science in 1887, and in 1884 he received the degree of LLD from Glasgow University. Among his many students at Owens College was J.J. (later Sir Joseph) Thomson (1856–1940), who entered the college in 1871. Reynolds's collected scientific papers were published in 1900–3.[br]Principal Honours and DistinctionsFRS 1877. Institution of Civil Engineers Telford Premium 1885.

106 Weber, Wilhelm Eduard
SUBJECT AREA: Electricity[br]b. 24 October 1804 Wittenberg, Germanyd. 23 June 1891 Göttingen, Germany[br]German physicist, the founder of precise measurement of electrical quantities.[br]Weber began scientific experiments at an early age and entered the University of Halle, where he came under the influence of J.S.C.Schweigger, inventor of the galvanometer. Completing his education with a dissertation on the theory of organ pipes and making important contributions to the science of acoustics, he was awarded a lectureship and later an assistant professorship at Halle. Weber was offered the Chair of Physics at Göttingen in 1831 and jointly with Gauss began investigations into the precision measurement of magnetic quantities. In 1841 he invented the electrodynamometer type of electrical measuring instrument. This was a development of the galvanometer in which, instead of a needle, a small coil was suspended within an outer coil. A current flowing through both coils tended to turn the inner coil, the sine of the angle through which the suspending wires were twisted being proportional to the square of the strength of the current. A variation of the electrodynamometer was capable of measuring directly the power in electrical circuits.The introduction by Weber of a system of absolute units for the measurement of electrical quantities was a most important step in electrical science. He had a considerable influence on the British Association committees on electrical standards organized in 1861 to promote a coherent system of electrical units. Weber's ideas also led him to define elementary electric particles, ascribing mass and charge to them. His name was used for a time before 1883 as the unit of electric current, until the name "ampere" was proposed by Helmholtz. Since 1948 the term "weber" has been used for the SI unit of magnetic flux.[br]Principal Honours and DistinctionsFRS 1850.

120 фондовый джоббер
фондовый джоббер
джоббер
“Делатель рынка” (market maker) на Лондонской фондовой бирже (London Stock Exchange) до “Бит Бэнга” (до октября 1986 г.). Фондовым джобберам разрешалось проводить сделки только с широкой публикой при посредничестве фондовых брокеров stockbroker). После “Бит Бэнга” система совмещения ролей была заменена системой разделения ролей (dual capacity system) “делателей рынка”. Прежде джобберы, чьи обязательства традиционно были не ограничены, зарабатывали себе на жизнь джобберским оборотом (jobbers turn), т.е. получали разницу между ценами, по которым они собирались покупать и продавать. После “Бит Бэнга” большинство лондонских джобберских фирм было поглощено более крупными финансовыми институтами, в основном банками.
