65 Swan, Sir Joseph Wilson
[br]b. 31 October 1828 Sunderland, Englandd. 27 May 1914 Warlingham, Surrey, England[br]English chemist, inventor in Britain of the incandescent electric lamp and of photographic processes.[br]At the age of 14 Swan was apprenticed to a Sunderland firm of druggists, later joining John Mawson who had opened a pharmacy in Newcastle. While in Sunderland Swan attended lectures at the Athenaeum, at one of which W.E. Staite exhibited electric-arc and incandescent lighting. The impression made on Swan prompted him to conduct experiments that led to his demonstration of a practical working lamp in 1879. As early as 1848 he was experimenting with carbon as a lamp filament, and by 1869 he had mounted a strip of carbon in a vessel exhausted of air as completely as was then possible; however, because of residual air, the filament quickly failed.Discouraged by the cost of current from primary batteries and the difficulty of achieving a good vacuum, Swan began to devote much of his attention to photography. With Mawson's support the pharmacy was expanded to include a photographic business. Swan's interest in making permanent photographic records led him to patent the carbon process in 1864 and he discovered how to make a sensitive dry plate in place of the inconvenient wet collodian process hitherto in use. He followed this success with the invention of bromide paper, the subject of a British patent in 1879.Swan resumed his interest in electric lighting. Sprengel's invention of the mercury pump in 1865 provided Swan with the means of obtaining the high vacuum he needed to produce a satisfactory lamp. Swan adopted a technique which was to become an essential feature in vacuum physics: continuing to heat the filament during the exhaustion process allowed the removal of absorbed gases. The inventions of Gramme, Siemens and Brush provided the source of electrical power at reasonable cost needed to make the incandescent lamp of practical service. Swan exhibited his lamp at a meeting in December 1878 of the Newcastle Chemical Society and again the following year before an audience of 700 at the Newcastle Literary and Philosophical Society. Swan's failure to patent his invention immediately was a tactical error as in November 1879 Edison was granted a British patent for his original lamp, which, however, did not go into production. Parchmentized thread was used in Swan's first commercial lamps, a material soon superseded by the regenerated cellulose filament that he developed. The cellulose filament was made by extruding a solution of nitro-cellulose in acetic acid through a die under pressure into a coagulating fluid, and was used until the ultimate obsolescence of the carbon-filament lamp. Regenerated cellulose became the first synthetic fibre, the further development and exploitation of which he left to others, the patent rights for the process being sold to Courtaulds.Swan also devised a modification of Planté's secondary battery in which the active material was compressed into a cellular lead plate.

67 Cross, Charles Frederick
[br]b. 11 December 1855 Brentwood, Middlesex, Englandd. 15 April 1935 Hove, England[br]English chemist who contributed to the development of viscose rayon from cellulose.[br]Cross was educated at the universities of London, Zurich and Manchester. It was at Owens College, Manchester, that Cross first met E.J. Bevan and where these two first worked together on the nature of cellulose. After gaining some industrial experience, Cross joined Bevan to set up a partnership in London as analytical and consulting chemists, specializing in the chemistry and technology of cellulose and lignin. They were at the Jodrell laboratory, Kew Gardens, for a time and then set up their own laboratory at Station Avenue, Kew Gardens. In 1888, the first edition of their joint publication A Textbook of Paper-making, appeared. It went into several editions and became the standard reference and textbook on the subject. The long introductory chapter is a discourse on cellulose.In 1892, Cross, Bevan and Clayton Beadle took out their historic patent on the solution and regeneration of cellulose. The modern artificial-fibre industry stems from this patent. They made their discovery at New Court, Carey Street, London: wood-pulp (or another cheap form of cellulose) was dissolved in a mixture of carbon disulphide and aqueous alkali to produce sodium xanthate. After maturing, it was squirted through fine holes into dilute acid, which set the liquid to give spinnable fibres of "viscose". However, it was many years before the process became a commercial operation, partly because the use of a natural raw material such as wood involved variations in chemical content and each batch might react differently. At first it was thought that viscose might be suitable for incandescent lamp filaments, and C.H.Stearn, a collaborator with Cross, continued to investigate this possibility, but the sheen on the fibres suggested that viscose might be made into artificial silk. The original Viscose Spinning Syndicate was formed in 1894 and a place was rented at Erith in Kent. However, it was not until some skeins of artificial silk (a term to which Cross himself objected) were displayed in Paris that textile manufacturers began to take an interest in it. It was then that Courtaulds decided to investigate this new fibre, although it was not until 1904 that they bought the English patents and developed the first artificial silk that was later called "rayon". Cross was also concerned with the development of viscose films and of cellulose acetate, which became a rival to rayon in the form of "Celanese". He retained his interest in the paper industry and in publishing, in 1895 again collaborating with Bevan and publishing a book on Cellulose and other technical articles. He was a cultured man and a good musician. He was elected a Fellow of the Royal Society in 1917.[br]Principal Honours and DistinctionsFRS 1917.Bibliography1888, with E.J.Bevan, A Text-book of Papermaking. 1892, British patent no. 8,700 (cellulose).Further ReadingObituary Notices of the Royal Society, 1935, London.

71 Nylon
Nylon was first made in the laboratories of E.I. du Pont de Nemours, of Wilmington, Delaware, U.S.A., under the direction of the late Dr. W. H. Carothers as a result of researches started 1928. In October, 1938, it -was announced to the world that a new form of textile fibre had been made by man, and that " nylon " was to be its name. Nylon stockings were on sale to the general public in U.S.A. on May 15, 1940, and many other items of wearing apparel were shown at the New York Pair that summer. In Great Britain, plans made jointly before the war by Courtaulds and Imperial Chemical Industries were responsible for production being started in 1941 by British Nylon Spinners Limited. The " 66 " polymer (each molecule of these reagents contains 6 carbon atoms and hence the name or designation " 66 ") was first made in 1935. Nylon is a name, not for a single material, but for a whole class or family of entirely new materials. There are many nylons and there may be many more. Nylon is the generic or family name for them all, just as glass and coal are names of classes of substances. Nylon, in the general sense, is a man-made material having a chemical composition akin to proteins, of which silk, hair and wool are examples, although nylon has not an exact counterpart in nature. It is not an " artificial " product, nor a man-made copy of a natural material. It can be made up into powders, sheets, solutions, strands or yarns, each with special properties according to requirements. The " 66 " polymer, from which yam is made, was synthesised in 1933, although not announced to the world until October, 1938. The raw material from which the diamine and acid for making " 66 " polymer are obtained are phenol from coal, oxygen and nitrogen from the air, and hydrogen from water. Particularly suitable where high elasticity is required. Uses include parachute fabrics, tyre cords, glider tow ropes, shoe laces webbing, braid, tape and thread, fully-fashioned hosiery, seamless hosiery, underwear fabrics, lace, nets, dress fabrics, marquisettes, neckties, transparent velvet, coated fabrics for raincoats and food covers. Industrial uses include shoe fabrics, sash cords, window screens, filters and bolting fabrics, also slip covers, motor car upholstery, shirtings, tents and shower curtains. -
72 Bevan, Edward John
[br]b. 11 December 1856 Birkenhead, Englandd. 17 October 1921 London, England[br]English co-inventor of the " viscose rayon " process for making artificial silk.[br]Bevan began his working life as a chemist in a soap works at Runcorn, but later studied chemistry at Owens College, Manchester. It was there that he met and formed a friendship with C.F. Cross, with whom he started to work on cellulose. Bevan moved to a paper mill in Scotland but then went south to London, where he and Cross set up a partnership in 1885 as consulting and analytical chemists. Their work was mainly concerned with the industrial utilization of cellulose, and with the problems of the paper and jute industries. Their joint publication, A Text-book of Paper-making, which first appeared in 1888 and went into several editions, became the standard reference and textbook on the subject. The book has a long introductory chapter on cellulose.In 1892 Cross, Bevan and Clayton Beadle discovered viscose, or sodium cellulose xanthate, and took out the patent which was to be the foundation of the "viscose rayon" industry. They had their own laboratory at Station Avenue, Kew Gardens, where they carried out much work that eventually resulted in viscose: cellulose, usually in the form of wood pulp, was treated first with caustic soda and then with carbon disulphide to form the xanthate, which was then dissolved in a solution of dilute caustic soda to produce a viscous liquid. After being aged, the viscose was extruded through fine holes in a spinneret and coagulated in a dilute acid to regenerate the cellulose as spinnable fibres. At first there was no suggestion of spinning it into fibre, but the hope was to use it for filaments in incandescent electric light bulbs. The sheen on the fibres suggested their possible use in textiles and the term "artificial silk" was later introduced. Cross and Bevan also discovered the acetate "Celanese", which was cellulose triacetate dissolved in acetone and spun in air, but both inventions needed much development before they could be produced commercially.In 1892 Bevan turned from cellulose to food and drugs and left the partnership to become Public Analyst to Middlesex County Council, a post he held until his death, although in 1895 he and Cross published their important work Cellulose. He was prominent in the affairs of the Society of Public Analysts and became one of its officials.[br]Bibliography1888, with C.F.Cross, A Text-book of Papermaking.1892, with C.F.Cross and C.Beadle, British patent no. 8,700 (viscose). 1895, with C.F.Cross, Cellulose.Further ReadingObituary, 1921, Journal of the Chemical Society.Obituary, 1921, Journal of the Society of Chemical Industry.Edwin J.Beer, 1962–3, "The birth of viscose rayon", Transactions of the Newcomen Society 35 (an account of the problems of developing viscose rayon; Beer worked under Cross in the Kew laboratories).RLH -
