123 Alexanderson, Ernst Frederik Werner
[br]b. 25 January 1878 Uppsala, Swedend. ? May 1975 Schenectady, New York, USA[br]Swedish-American electrical engineer and prolific radio and television inventor responsible for developing a high-frequency alternator for generating radio waves.[br]After education in Sweden at the High School and University of Lund and the Royal Institution of Technology in Stockholm, Alexanderson took a postgraduate course at the Berlin-Charlottenburg Engineering College. In 1901 he began work for the Swedish C \& C Electric Company, joining the General Electric Company, Schenectady, New York, the following year. There, in 1906, together with Fessenden, he developed a series of high-power, high-frequency alternators, which had a dramatic effect on radio communications and resulted in the first real radio broadcast. His early interest in television led to working demonstrations in his own home in 1925 and at the General Electric laboratories in 1927, and to the first public demonstration of large-screen (7 ft (2.13 m) diagonal) projection TV in 1930. Another invention of significance was the "amplidyne", a sensitive manufacturing-control system subsequently used during the Second World War for controlling anti-aircraft guns. He also contributed to developments in electric propulsion and radio aerials.He retired from General Electric in 1948, but continued television research as a consultant for the Radio Corporation of America (RCA), filing his 321st patent in 1955.[br]Principal Honours and DistinctionsInstitution of Radio Engineers Medal of Honour 1919.

124 Cowper-Coles, Sherard Osborn
SUBJECT AREA: Metallurgy[br]b. 8 October 1866 East Harting, Sussex, Englandd. 9 September 1936[br]English inventor of the sherardizing process for metal protection.[br]He was the son of Captain Cowper- Coles, Royal Navy, the inventor of the swivelling turret for naval guns. He inherited his father's inventive talents and investigated a variety of inventions in his workshop at his home at Sunbury-on-Thames, assisted by a number of scientific workers. He had been educated by governesses, but he lacked a sound scientific background. His inventions, rarely systematically pursued, ranged from electrolytic processes for making copper sheets and parabolic reflectors to a process for inlaying and decorating metallic surfaces. Overall, however, he is best known for the invention of "sherardizing", the process for producing a rustproof coating of zinc on small metallic articles. The discovery came by chance, when he was annealing iron and steel packed in zinc dust to exclude air. The metal was found to be coated with a thin layer of zinc with some surface penetration. The first patent for the process was obtained in 1900, and later the American rights were sold, with a company being formed in 1908 to control them. A small plant was set up in Chelsea, London, to develop the process to the point where it could be carried out on a commercial scale in a plant in Willesden. Sherardizing has not been a general protective finish, but is restricted to articles such as nuts and bolts which are then painted or finished. The process was still in use in 1977, operated by the Zinc Alloy Company (London) Ltd.[br]Further ReadingC.A.Smith, 1978, "Sherard Cowper-Coles: a review of the inception of sherardizing", Transactions of the Newcomen Society 49:1–4.LRDBiographical history of technology > Cowper-Coles, Sherard Osborn

125 Crompton, Samuel
SUBJECT AREA: Textiles[br]b. 3 December 1753 Firwood, near Bolton, Lancashire, Englandd. 26 June 1827 Bolton, Lancashire, England[br]English inventor of the spinning mule.[br]Samuel Crompton was the son of a tenant farmer, George, who became the caretaker of the old house Hall-i-th-Wood, near Bolton, where he died in 1759. As a boy, Samuel helped his widowed mother in various tasks at home, including weaving. He liked music and made his own violin, with which he later was to earn some money to pay for tools for building his spinning mule. He was set to work at spinning and so in 1769 became familiar with the spinning jenny designed by James Hargreaves; he soon noticed the poor quality of the yarn produced and its tendency to break. Crompton became so exasperated with the jenny that in 1772 he decided to improve it. After seven years' work, in 1779 he produced his famous spinning "mule". He built the first one entirely by himself, principally from wood. He adapted rollers similar to those already patented by Arkwright for drawing out the cotton rovings, but it seems that he did not know of Arkwright's invention. The rollers were placed at the back of the mule and paid out the fibres to the spindles, which were mounted on a moving carriage that was drawn away from the rollers as the yarn was paid out. The spindles were rotated to put in twist. At the end of the draw, or shortly before, the rollers were stopped but the spindles continued to rotate. This not only twisted the yarn further, but slightly stretched it and so helped to even out any irregularities; it was this feature that gave the mule yarn extra quality. Then, after the spindles had been turned backwards to unwind the yarn from their tips, they were rotated in the spinning direction again and the yarn was wound on as the carriage was pushed up to the rollers.The mule was a very versatile machine, making it possible to spin almost every type of yarn. In fact, Samuel Crompton was soon producing yarn of a much finer quality than had ever been spun in Bolton, and people attempted to break into Hall-i-th-Wood to see how he produced it. Crompton did not patent his invention, perhaps because it consisted basically of the essential features of the earlier machines of Hargreaves and Arkwright, or perhaps through lack of funds. Under promise of a generous subscription, he disclosed his invention to the spinning industry, but was shabbily treated because most of the promised money was never paid. Crompton's first mule had forty-eight spindles, but it did not long remain in its original form for many people started to make improvements to it. The mule soon became more popular than Arkwright's waterframe because it could spin such fine yarn, which enabled weavers to produce the best muslin cloth, rivalling that woven in India and leading to an enormous expansion in the British cotton-textile industry. Crompton eventually saved enough capital to set up as a manufacturer himself and around 1784 he experimented with an improved carding engine, although he was not successful. In 1800, local manufacturers raised a sum of £500 for him, and eventually in 1812 he received a government grant of £5,000, but this was trifling in relation to the immense financial benefits his invention had conferred on the industry, to say nothing of his expenses. When Crompton was seeking evidence in 1811 to support his claim for financial assistance, he found that there were 4,209,570 mule spindles compared with 155,880 jenny and 310,516 waterframe spindles. He later set up as a bleacher and again as a cotton manufacturer, but only the gift of a small annuity by his friends saved him from dying in total poverty.[br]Further ReadingH.C.Cameron, 1951, Samuel Crompton, Inventor of the Spinning Mule, London (a rather discursive biography).Dobson \& Barlow Ltd, 1927, Samuel Crompton, the Inventor of the Spinning Mule, Bolton.G.J.French, 1859, The Life and Times of Samuel Crompton, Inventor of the Spinning Machine Called the Mule, London.The invention of the mule is fully described in H.

126 Edwards, Humphrey
SUBJECT AREA: Steam and internal combustion engines[br]fl. c.1808–25 London (?), Englandd. after 1825 France (?)[br]English co-developer of Woolf s compound steam engine.[br]When Arthur Woolf left the Griffin Brewery, London, in October 1808, he formed a partnership with Humphrey Edwards, described as a millwright at Mill Street, Lambeth, where they started an engine works to build Woolf's type of compound engine. A number of small engines were constructed and other ordinary engines modified with the addition of a high-pressure cylinder. Improvements were made in each succeeding engine, and by 1811 a standard form had been evolved. During this experimental period, engines were made with cylinders side by side as well as the more usual layout with one behind the other. The valve gear and other details were also improved. Steam pressure may have been around 40 psi (2.8 kg/cm2). In an advertisement of February 1811, the partners claimed that their engines had been brought to such a state of perfection that they consumed only half the quantity of coal required for engines on the plan of Messrs Boulton \& Watt. Woolf visited Cornwall, where he realized that more potential for his engines lay there than in London; in May 1811 the partnership was dissolved, with Woolf returning to his home county. Edwards struggled on alone in London for a while, but when he saw a more promising future for the engine in France he moved to Paris. On 25 May 1815 he obtained a French patent, a Brevet d'importation, for ten years. A report in 1817 shows that during the previous two years he had imported into France fifteen engines of different sizes which were at work in eight places in various parts of the country. He licensed a mining company in the north of France to make twenty-five engines for winding coal. In France there was always much more interest in rotative engines than pumping ones. Edwards may have formed a partnership with Goupil \& Cie, Dampierre, to build engines, but this is uncertain. He became a member of the firm Scipion, Perrier, Edwards \& Chappert, which took over the Chaillot Foundry of the Perrier Frères in Paris, and it seems that Edwards continued to build steam engines there for the rest of his life. In 1824 it was claimed that he had made about 100 engines in England and another 200 in France, but this is probably an exaggeration.The Woolf engine acquired its popularity in France because its compound design was more economical than the single-cylinder type. To enable it to be operated safely, Edwards first modified Woolf s cast-iron boiler in 1815 by placing two small drums over the fire, and then in 1825 replaced the cast iron with wrought iron. The modified boiler was eventually brought back to England in the 1850s as the "French" or "elephant" boiler.[br]Further ReadingMost details about Edwards are to be found in the biographies of his partner, Arthur Woolf. For example, see T.R.Harris, 1966, Arthur Woolf, 1766–1837, The Cornish Engineer, Truro: D.Bradford Barton; Rhys Jenkins, 1932–3, "A Cornish Engineer, Arthur Woolf, 1766–1837", Transactions of the Newcomen Society 13.

127 Hoover, William Henry
SUBJECT AREA: Domestic appliances and interiors[br]b. 1849 New Berlin (now North Canton), Ohio, USAd. 25 February 1932 North Canton, Ohio, USA[br]American founder of the Electric Suction Company, which manufactured and successfully marketed the first practical and portable suction vacuum cleaner.[br]Hoover was descended from a Swiss farming family called Hofer who emigrated from Basle and settled in Lancaster County, Pennsylvania, in the early eighteenth century. By 1832 the family had become tanners and lived near North Berlin in Ohio. In 1870 William Henry Hoover, who had studied at Mount Union College, bought the tannery with his brothers and soon expanded the business to make horse collars and saddlery. The firm expanded to become W.H.Hoover \& Co. In the early years of the first decade of the twentieth century, horses were beginning to be replaced by the internal combustion engine, so Hoover needed a new direction for his firm. This he found in the suction vacuum cleaner devised in 1907 by J.Murray Spangler, a cousin of Hoover's wife. The first successful cleaner of this type had been operating in England since 1901 (see Booth), but was not a portable model. Attracted by the development of the small electric motor, Spangler produced a vertical cleaner with such a motor that sucked the dust through the machine and blew it into a bag attached to the handle. Spangler applied for a patent for his invention on 14 September in the same year; it was granted for a carpet sweeper and cleaner on 2 June 1908, but Spangler was unable to market it himself and sold the rights to Hoover. The Model O machine, which ran on small wheels, was immediately manufactured and marketed. Hoover's model was the first electric, one-person-operated, domestic vacuum cleaner and was instantly successful, although the main expansion of the business was delayed for some time until the greater proportion of houses were wired for electricity. The Hoover slogan, "it beats as it sweeps as it cleans", came to be true in 1926 with the introduction of the Model 700, which was the first cleaner to offer triple-action cleaning, a process which beat, swept and sucked at the carpet. Further advances in the 1930s included the use of magnesium and the early plastics.[br]Further ReadingG.Adamson, 1969, Machines at Home, Lutterworth Press.How it Works: The Universal Encyclopaedia of Machines, Paladin.

128 Mouriés, Hippolyte Mège
SUBJECT AREA: Agricultural and food technology[br]b. 24 October 1817 Draguignan, Franced. 1880 France[br]French inventor of margarine.[br]The son of a schoolmaster. Mouriés became a chemist's assistant in his home town at the age of 16. He then spent a period of training in Aix-enProvence, and in 1838 he moved to Paris, where he became Assistant to the Resident Pharmacist at the Hotel Dieu Hospital. He stayed there until 1846 but never sat his final exams. His main success during this period was with the drug Copahin, which was used against syphilis; he invented an oral formulation of the drug by treating it with nitric acid. In the 1840s he took out various patents relating to tanning and to sugar extraction, and in the 1850s he turned his attention to food research. He developed a health chocolate with his calcium phosphate protein, and also developed a method that made it possible to gain 14 per cent more white bread from a given quantity of wheat. He lectured on this process in Berlin and Brussels and was awarded two gold medals. After 1862 he concentrated his research on fats. His margarine process was based on the cold saponification of milk in fat emulsions and was patented in both France and Britain in 1869. These experiments were carried out at the Ferme Impériale de La Faisanderie in Vincennes, the personal property of the Emperor, and it is therefore likely that they were State-funded. He sold his knowledge to the Dutch firm Jurgens in 1871, and between 1873 and 1874 he also sold his British, American and Prussian rights. His final patent, in 1875, was for canned meat.[br]Principal Honours and DistinctionsNapoleon III awarded him the Légion d'honneur for his work on wheat and bread.Further ReadingJ.H.van Stuyvenberg (ed.), Margarine: An Economic, Social and Scientific History, 1869–1969 (provides a brief outline of the life of Mouriés in a comprehensive history of his discovery).APBiographical history of technology > Mouriés, Hippolyte Mège
