8 Harrison, John
[br]b. 24 March 1693 Foulby, Yorkshire, Englandd. 24 March 1776 London, England[br]English horologist who constructed the first timekeeper of sufficient accuracy to determine longitude at sea and invented the gridiron pendulum for temperature compensation.[br]John Harrison was the son of a carpenter and was brought up to that trade. He was largely self-taught and learned mechanics from a copy of Nicholas Saunderson's lectures that had been lent to him. With the assistance of his younger brother, James, he built a series of unconventional clocks, mainly of wood. He was always concerned to reduce friction, without using oil, and this influenced the design of his "grasshopper" escapement. He also invented the "gridiron" compensation pendulum, which depended on the differential expansion of brass and steel. The excellent performance of his regulator clocks, which incorporated these devices, convinced him that they could also be used in a sea dock to compete for the longitude prize. In 1714 the Government had offered a prize of £20,000 for a method of determining longitude at sea to within half a degree after a voyage to the West Indies. In theory the longitude could be found by carrying an accurate timepiece that would indicate the time at a known longitude, but the requirements of the Act were very exacting. The timepiece would have to have a cumulative error of no more than two minutes after a voyage lasting six weeks.In 1730 Harrison went to London with his proposal for a sea clock, supported by examples of his grasshopper escapement and his gridiron pendulum. His proposal received sufficient encouragement and financial support, from George Graham and others, to enable him to return to Barrow and construct his first sea clock, which he completed five years later. This was a large and complicated machine that was made out of brass but retained the wooden wheelwork and the grasshopper escapement of the regulator clocks. The two balances were interlinked to counteract the rolling of the vessel and were controlled by helical springs operating in tension. It was the first timepiece with a balance to have temperature compensation. The effect of temperature change on the timekeeping of a balance is more pronounced than it is for a pendulum, as two effects are involved: the change in the size of the balance; and the change in the elasticity of the balance spring. Harrison compensated for both effects by using a gridiron arrangement to alter the tension in the springs. This timekeeper performed creditably when it was tested on a voyage to Lisbon, and the Board of Longitude agreed to finance improved models. Harrison's second timekeeper dispensed with the use of wood and had the added refinement of a remontoire, but even before it was tested he had embarked on a third machine. The balance of this machine was controlled by a spiral spring whose effective length was altered by a bimetallic strip to compensate for changes in temperature. In 1753 Harrison commissioned a London watchmaker, John Jefferys, to make a watch for his own personal use, with a similar form of temperature compensation and a modified verge escapement that was intended to compensate for the lack of isochronism of the balance spring. The time-keeping of this watch was surprisingly good and Harrison proceeded to build a larger and more sophisticated version, with a remontoire. This timekeeper was completed in 1759 and its performance was so remarkable that Harrison decided to enter it for the longitude prize in place of his third machine. It was tested on two voyages to the West Indies and on both occasions it met the requirements of the Act, but the Board of Longitude withheld half the prize money until they had proof that the timekeeper could be duplicated. Copies were made by Harrison and by Larcum Kendall, but the Board still continued to prevaricate and Harrison received the full amount of the prize in 1773 only after George III had intervened on his behalf.Although Harrison had shown that it was possible to construct a timepiece of sufficient accuracy to determine longitude at sea, his solution was too complex and costly to be produced in quantity. It had, for example, taken Larcum Kendall two years to produce his copy of Harrison's fourth timekeeper, but Harrison had overcome the psychological barrier and opened the door for others to produce chronometers in quantity at an affordable price. This was achieved before the end of the century by Arnold and Earnshaw, but they used an entirely different design that owed more to Le Roy than it did to Harrison and which only retained Harrison's maintaining power.[br]Principal Honours and DistinctionsRoyal Society Copley Medal 1749.Bibliography1767, The Principles of Mr Harrison's Time-keeper, with Plates of the Same, London. 1767, Remarks on a Pamphlet Lately Published by the Rev.

9 Winans, Ross
[br]b. 17 October 1796 Sussex County, New Jersey, USAd. 11 April 1877 Baltimore, Maryland, USA[br]American inventor and locomotive builder.[br]Winans arrived in Baltimore in 1828 to sell horses to the Baltimore \& Ohio Railroad (B \& O), which was then under construction. To reduce friction in rail vehicles, he devised a system of axles which ran in oil-baths, with outside bearings. He demonstrated a hand-driven wagon with this system at the Rainhill Trials; the Liverpool \& Manchester Railway bought some wagons fitted with the system, but found them on test to be inferior to wagons with grease axle boxes. Back in Baltimore, Winans assisted Peter Cooper in building Tom Thumb. He took charge of the B \& O shops c.1834; he is said to have built the first eight-wheeled passenger coach and to have been the first to mount such a coach on two four-wheeled trucks or bogies. The arrangement soon became standard American practice, and, with partners, he built over 100 locomotives for the B \& O. In 1847 he pioneered the use of anthracite as locomotive fuel, and from 1848 he built his "Camel" locomotives with the driver's cab above the boiler.[br]Further ReadingJ.H.White Jr, 1979, A History of the American Locomotive-Its Development: 1830–1880, New York: Dover Publications Inc.P.Ransome-Wallis (ed.), 1959, The Concise Encyclopaedia of World Railway Locomotives, London: Hutchinson, p. 503 (biography).Dictionary of American Biography.H.Booth, 1980, Henry Booth, Ilfracombe: Arthur H.Stockwell, pp. 75 and 91–2 (for the Liverpool \& Manchester wagons).See also: Stephenson, GeorgePJGR -

12 уменьшать
Глагол уменьшать передается английскими lessen, decrease, reduce, diminish и minimize. Lessen имеет в виду уменьшение числа или интенсивности (желания, ощущения и т. д.): to lessen the number of books, to lessen one's desire, to lessen the pain. Decrease обычно предполагает длительное или прогрессирующее уменьшение: his temperature decreases, her fears decreased with the approach of dawn. В отличие от русского глагола уменьшать, употребляющегося с предлогом на (уменьшать на какую-л. сумму, величину и пр.), decrease требует дополнения с предлогом by: уменьшать (снижать) на 20% – to decrease by 20 per cent. Reduce определяет главным образом уменьшение размера, количества, веса, протяженности: to reduce the price, to reduce the distance, to reduce the weight. Diminish имеет в виду уменьшение, связанное с потерей, утратой – to diminish the country's wealth, to diminish food supplies. Minimize означает 'доводить до предельного минимума': to minimize the friction.Трудности английского языка (лексический справочник). Русско-английский словарь > уменьшать
