94 Flax Fibre, Tow And By-Products
FLAX FIBRE, TOW and BY-PRODUCTSFlax, Broken - Scutched flax which is less than 20-in. long and therefore unfit for hackling in the spinning mill. Flax, C.D. and T. - Graders' marks which denote the type of scutched flax: c (chaine) to represent warps, D (demi) to represent medium warps, and T (trame) to represent wefts. Flax, Green, or Natural - Scutched flax produced from de-seeded straw without any intermediate treatment such as retting. Flax, Line - The hackled flax produced by a hackling machine or hand hackling. A term sometimes erroneously applied to scutched flax. Flax, Retted - Scutched flax produced from straw which has been retted. Usually divided into three main classes, namely, water retted flax, dew retted flax, and chemically retted flax. Flax, Scutched - The product from the delivery end of a scutching machine or from scutching flax straw on a wheel. It consists of the long fibre strands in a parallel condition and substantially free from wood and other extraneous material. The yield of scutched flax is commonly expressed as stones (14-lb.) per acre, but in Ireland it is sometimes expressed as stones per peck of seed sown. The average yield per acre of scutched flax has varied according to year from about 20 stones per acre to 40 stones per acre, with occasional exceptional yields of 80 and 90 stones per acre. Grader, Flax - The man who places the scutched flaxes in their appropriate grades of quality by eye judgment and feel. Grades, Flax - Tank retted flaxes are graded from A through the alphabet in ascending order of value. Dam retted flaxes are graded from 1-7 in descending order of value. Dew retted flaxes are graded 0-6 in descending order of value. Grades, Tow - Green tow is graded 1-8 and then 9a, 9b, Z, Z2, and beater tow in descending order of value. Tank retted tow is graded I, II, III, 1, 2, 3, 3X, 3XXX, in descending order, whilst dam and dew retted tows are I, II, II, 1, 2, 3. Pluckings - The short, clean fibre produced at the end of the scutching machine where the operatives dress and square the pieces of flax ready for selection. In grading pluckings are classed as tow (q.v.). Root Ends, Straw - The broken-off roots which fall from the straw under the breaking rollers. Rug, Scutching - All the detritus which falls below the two compartments of the scutching machine after the shives have been shaken out of it, or the waste made when producing scutched flax on a wheel. It consists of partly scutched short straws, broken straws, weeds, and beater tow. It is classed as root end rug or top end rug, according to which end of the flax it comes from. Selection - The preliminary sorting of the scutched flax into main grades at the delivery end of the scutching machine. Shives - The short pieces of woody waste beaten from the straw during scutching. Tow - Any substantially clean but tossed and tangled flax fibre of less than scutched flax length. Tow Baling - The operation of making-up tow into bales. Tow, Beater - Short, fine, clean fibres which fall from the last third of the compartments during scutching. Tow, Inferior low grade (Green) - Green tow of a grade lower than 9a. Tow, Inferior low grade (Retted) - Retted tow of a grade lower than 3XXX. Tow, Machine, or Cast - Tow produced by the hackling machine. Tow, Rejected - Tow unsuitable for spinning on flax tow machinery. Tow, Rescutched - Two scutched on tow handles or a tow scutching machine. Tow, Rolled - The product from passing scutching rug through tow rollers and highspeed shaker. Tow, Rolled and Beaten - The product from passing scutching rug through tow rollers and beaters, and a high-speed shaker. The principal flax markets of the world are at Courtrai, Bruges, Ghent, Lokeren and Zele in Belgium; Rotterdam in Holland; Riga in Latvia; Leningrad, Pernau and Witebek in Russia; Douai and Flines in France; Newry, Rathfriland, Strabane, Ballymoney, Lisnaskea, Ballybay and Armagh in Ireland. Courtrai flax is the finest produced. It is uniform in fibre, strong, clean and of a good colour. Yarns up to 200's lea are spun from it. Irish flax comes next in spinning qualities from 90's to 120's lea are produced. As a warp yarn it is much preferred as the strength is greater than other types. Flemish flax is dark in colour, dryer than others, strong, and can be spun up to 120's lea. Dutch flax is clean, good colour and spins into yams up to 90's lea. Russian flax is coarser than the above types and is usually spun up to about 70's lea.Dictionary of the English textile terms > Flax Fibre, Tow And By-Products

96 De Forest, Lee
SUBJECT AREA: Broadcasting, Electronics and information technology, Photography, film and optics, Recording, Telecommunications[br]b. 26 August 1873 Council Bluffs, Iowa, USAd. 30 June 1961 Hollywood, California, USA[br]American electrical engineer and inventor principally known for his invention of the Audion, or triode, vacuum tube; also a pioneer of sound in the cinema.[br]De Forest was born into the family of a Congregational minister that moved to Alabama in 1879 when the father became President of a college for African-Americans; this was a position that led to the family's social ostracism by the white community. By the time he was 13 years old, De Forest was already a keen mechanical inventor, and in 1893, rejecting his father's plan for him to become a clergyman, he entered the Sheffield Scientific School of Yale University. Following his first degree, he went on to study the propagation of electromagnetic waves, gaining a PhD in physics in 1899 for his thesis on the "Reflection of Hertzian Waves from the Ends of Parallel Wires", probably the first US thesis in the field of radio.He then joined the Western Electric Company in Chicago where he helped develop the infant technology of wireless, working his way up from a modest post in the production area to a position in the experimental laboratory. There, working alone after normal working hours, he developed a detector of electromagnetic waves based on an electrolytic device similar to that already invented by Fleming in England. Recognizing his talents, a number of financial backers enabled him to set up his own business in 1902 under the name of De Forest Wireless Telegraphy Company; he was soon demonstrating wireless telegraphy to interested parties and entering into competition with the American Marconi Company.Despite the failure of this company because of fraud by his partners, he continued his experiments; in 1907, by adding a third electrode, a wire mesh, between the anode and cathode of the thermionic diode invented by Fleming in 1904, he was able to produce the amplifying device now known as the triode valve and achieve a sensitivity of radio-signal reception much greater than possible with the passive carborundum and electrolytic detectors hitherto available. Patented under the name Audion, this new vacuum device was soon successfully used for experimental broadcasts of music and speech in New York and Paris. The invention of the Audion has been described as the beginning of the electronic era. Although much development work was required before its full potential was realized, the Audion opened the way to progress in all areas of sound transmission, recording and reproduction. The patent was challenged by Fleming and it was not until 1943 that De Forest's claim was finally recognized.Overcoming the near failure of his new company, the De Forest Radio Telephone Company, as well as unsuccessful charges of fraudulent promotion of the Audion, he continued to exploit the potential of his invention. By 1912 he had used transformer-coupling of several Audion stages to achieve high gain at radio frequencies, making long-distance communication a practical proposition, and had applied positive feedback from the Audion output anode to its input grid to realize a stable transmitter oscillator and modulator. These successes led to prolonged patent litigation with Edwin Armstrong and others, and he eventually sold the manufacturing rights, in retrospect often for a pittance.During the early 1920s De Forest began a fruitful association with T.W.Case, who for around ten years had been working to perfect a moving-picture sound system. De Forest claimed to have had an interest in sound films as early as 1900, and Case now began to supply him with photoelectric cells and primitive sound cameras. He eventually devised a variable-density sound-on-film system utilizing a glow-discharge modulator, the Photion. By 1926 De Forest's Phonofilm had been successfully demonstrated in over fifty theatres and this system became the basis of Movietone. Though his ideas were on the right lines, the technology was insufficiently developed and it was left to others to produce a system acceptable to the film industry. However, De Forest had played a key role in transforming the nature of the film industry; within a space of five years the production of silent films had all but ceased.In the following decade De Forest applied the Audion to the development of medical diathermy. Finally, after spending most of his working life as an independent inventor and entrepreneur, he worked for a time during the Second World War at the Bell Telephone Laboratories on military applications of electronics.[br]Principal Honours and DistinctionsInstitute of Electronic and Radio Engineers Medal of Honour 1922.

97 Eccles, William Henry
[br]b. 23 August 1875 Ulverston, Cumbria, Englandd. 27 April 1966 Oxford, England[br]English physicist who made important contributions to the development of radio communications.[br]After early education at home and at private school, Eccles won a scholarship to the Royal College of Science (now Imperial College), London, where he gained a First Class BSc in physics in 1898. He then worked as a demonstrator at the college and studied coherers, for which he obtained a DSc in 1901. Increasingly interested in electrical engineering, he joined the Marconi Company in 1899 to work on oscillators at the Poole experimental radio station, but in 1904 he returned to academic life as Professor of Mathematics and Physics and Department Head at South West Polytechnic, Chelsea. There he discovered ways of using the negative resistance of galena-crystal detectors to generate oscillations and gave a mathematical description of the operation of the triode valve. In 1910 he became Reader in Engineering at University College, London, where he published a paper explaining the reflection of radio waves by the ionosphere and designed a 60 MHz short-wave transmitter. From 1916 to 1926 he was Professor of Applied Physics and Electrical Engineering at the Finsbury City \& Guilds College and a private consulting engineer. During the First World War he was a military scientific adviser and Secretary to the Joint Board of Scientific Societies. After the war he made many contributions to electronic-circuit development, many of them (including the Eccles-Jordan "flip-flop" patented in 1918 and used in binary counters) in conjunction with F.W.Jordan, about whom little seems to be known. Illness forced Eccles's premature academic retirement in 1926, but he remained active as a consultant for many years.[br]Principal Honours and DistinctionsFRS 1921.

98 Fermi, Enrico
[br]b. 29 September 1901 Rome, Italyd. 28 November 1954 Chicago, USA[br]Italian nuclear physicist.[br]Fermi was one of the most versatile of twentieth-century physicists, one of the few to excel in both theory and experiment. His greatest theoretical achievements lay in the field of statistics and his theory of beta decay. His statistics, parallel to but independent of Dirac, were the key to the modern theory of metals and the statistical modds of the atomic nucleus. On the experimental side, his most notable discoveries were artificial radioactivity produced by neutron bombardment and the realization of a controlled nuclear chain reaction, in the world's first nuclear reactor.Fermi received a conventional education with a chemical bias, but reached proficiency in mathematics and physics largely through his own reading. He studied at Pisa University, where he taught himself modern physics and then travelled to extend his knowledge, spending time with Max Born at Göttingen. On his return to Italy, he secured posts in Florence and, in 1927, in Rome, where he obtained the first Italian Chair in Theoretical Physics, a subject in which Italy had so far lagged behind. He helped to bring about a rebirth of physics in Italy and devoted himself to the application of statistics to his model of the atom. For this work, Fermi was awarded the Nobel Prize in Physics in 1938, but in December of that year, finding the Fascist regime uncongenial, he transferred to the USA and Columbia University. The news that nuclear fission had been achieved broke shortly before the Second World War erupted and it stimulated Fermi to consider this a way of generating secondary nuclear emission and the initiation of chain reactions. His experiments in this direction led first to the discovery of slow neutrons.Fermi's work assumed a more practical aspect when he was invited to join the Manhattan Project for the construction of the first atomic bomb. His small-scale work at Columbia became large-scale at Chicago University. This culminated on 2 December 1942 when the first controlled nuclear reaction took place at Stagg Field, Chicago, an historic event indeed. Later, Fermi spent most of the period from September 1944 to early 1945 at Los Alamos, New Mexico, taking part in the preparations for the first test explosion of the atomic bomb on 16 July 1945. President Truman invited Fermi to serve on his Committee to advise him on the use of the bomb. Then Chicago University established an Institute for Nuclear Studies and offered Fermi a professorship, which he took up early in 1946, spending the rest of his relatively short life there.[br]Principal Honours and DistinctionsNobel Prize for Physics 1938.Bibliography1962–5, Collected Papers, ed.

99 Forrester, Jay Wright
SUBJECT AREA: Electronics and information technology[br]b. 14 July 1918 Anselmo, Nebraska, USA[br]American electrical engineer and management expert who invented the magnetic-core random access memory used in most early digital computers.[br]Born on a cattle ranch, Forrester obtained a BSc in electrical engineering at the University of Nebraska in 1939 and his MSc at the Massachusetts Institute of Technology (MIT) in Cambridge, Massachusetts, where he remained to teach and carry out research. Becoming interested in computing, he established the Digital Computer Laboratory at MIT in 1945 and became involved in the construction of Whirlwind I, an early general-purpose computer completed in March 1951 and used for flight-simulation by the US Army Air Force. Finding the linear memories then available for storing data a major limiting factor in the speed at which computers were able to operate, he developed a three-dimensional store based on the binary switching of the state of small magnetic cores that could be addressed and switched by a matrix of wires carrying pulses of current. The machine used parallel synchronous fixed-point computing, with fifteen binary digits and a plus sign, i.e. 16 bits in all, and contained 5,000 vacuum tubes, eleven semiconductors and a 2 MHz clock for the arithmetic logic unit. It occupied a two-storey building and consumed 150kW of electricity. From his experience with the development and use of computers, he came to realize their great potential for the simulation and modelling of real situations and hence for the solution of a variety of management problems, using data communications and the technique now known as interactive graphics. His later career was therefore in this field, first at the MIT Lincoln Laboratory in Lexington, Massachusetts (1951) and subsequently (from 1956) as Professor at the Sloan School of Management at the Massachusetts Institute of Technology.[br]Principal Honours and DistinctionsNational Academy of Engineering 1967.

SUBJECT AREA: Telecommunications[br]b. 28 January 1755 Torun, Poland (later Thorn, Prussia)d. 2 March 1830 Frankfurt, Germany[br]German physician who devised an early form of electric telegraph.[br]Soemmerring appears to have been a distinguished anatomist and physiologist who in 1805 became a member of the Munich Academy of Sciences. Whilst experimenting with electric currents in acid solutions in 1809, he observed the bubbles of gases produced by the dissociation process. Using this effect at the receiver, he devised a telegraph consisting of twenty-six parallel wires (one for each letter of the alphabet) and was able to transmit messages over a distance of 2 miles (3 km), but the idea was not commercially viable. In 1812, with the help of Schilling, he experimented with soluble indiarubber as a possible cable insulator.[br]Principal Honours and DistinctionsKnight of the Order of St Anne of Russia 1818. Hon.
