15 Graham, George
SUBJECT AREA: Horology[br]b. c.1674 Cumberland, Englandd. 16 November 1751 London, England[br]English watch-and clockmaker who invented the cylinder escapement for watches, the first successful dead-beat escapement for clocks and the mercury compensation pendulum.[br]Graham's father died soon after his birth, so he was raised by his brother. In 1688 he was apprenticed to the London clockmaker Henry Aske, and in 1695 he gained his freedom. He was employed as a journeyman by Tompion in 1696 and later married his niece. In 1711 he formed a partnership with Tompion and effectively ran the business in Tompion's declining years; he took over the business after Tompion died in 1713. In addition to his horological interests he also made scientific instruments, specializing in those for astronomical use. As a person, he was well respected and appears to have lived up to the epithet "Honest George Graham". He befriended John Harrison when he first went to London and lent him money to further his researches at a time when they might have conflicted with his own interests.The two common forms of escapement in use in Graham's time, the anchor escapement for clocks and the verge escapement for watches, shared the same weakness: they interfered severely with the free oscillation of the pendulum and the balance, and thus adversely affected the timekeeping. Tompion's two frictional rest escapements, the dead-beat for clocks and the horizontal for watches, had provided a partial solution by eliminating recoil (the momentary reversal of the motion of the timepiece), but they had not been successful in practice. Around 1720 Graham produced his own much improved version of the dead-beat escapement which became a standard feature of regulator clocks, at least in Britain, until its supremacy was challenged at the end of the nineteenth century by the superior accuracy of the Riefler clock. Another feature of the regulator clock owed to Graham was the mercury compensation pendulum, which he invented in 1722 and published four years later. The bob of this pendulum contained mercury, the surface of which rose or fell with changes in temperature, compensating for the concomitant variation in the length of the pendulum rod. Graham devised his mercury pendulum after he had failed to achieve compensation by means of the difference in expansion between various metals. He then turned his attention to improving Tompion's horizontal escapement, and by 1725 the cylinder escapement existed in what was virtually its final form. From the following year he fitted this escapement to all his watches, and it was also used extensively by London makers for their precision watches. It proved to be somewhat lacking in durability, but this problem was overcome later in the century by using a ruby cylinder, notably by Abraham Louis Breguet. It was revived, in a cheaper form, by the Swiss and the French in the nineteenth century and was produced in vast quantities.[br]Principal Honours and DistinctionsFRS 1720.

19 Blackett, William Cuthbert
SUBJECT AREA: Mining and extraction technology[br]b. 18 November 1859 Durham, Englandd. 13 June 1935 Durham, England[br]English mine manager, expert in preventing mine explosions and inventor of a coal-face conveyor.[br]After leaving Durham college of Physical Science and having been apprenticed in different mines, he received the certificate for colliery managers and subsequently, in 1887, was appointed Manager of all the mines of Charlaw and Sacriston collieries in Durham. He remained in this position for the rest of his working life.Frequent explosions in mines led him to investigate the causes. He was among the first to recognize the role contributed by coal-dust on mine roads, pioneered the use of inert rock-or stone-dust to render the coal-dust harmless and was the originator of many technical terms on the subject. He contributed many papers on explosion and was appointed a member of many advisory committees on prevention measures. A liquid-air rescue apparatus, designed by him and patented in 1910, was installed in various parts of the country.Blackett also developed various new devices in mining machinery. He patented a wire-rope socket which made use of a metal wedge; invented a rotary tippler driven by frictional contact instead of gearing and which stopped automatically; and he designed a revolving cylindrical coal-washer, which also gained interest among German mining engineers. His most important invention, the first successful coal-face conveyor, was patented in 1902. It was driven by compressed air and consisted of a trough running along the length of the race through which ran an endless scraper chain. Thus fillers cast the coal into the trough, and the scraper chain drew it to the main gate to be loaded into trams.[br]Principal Honours and DistinctionsKnight of Grace of the Order of St John of Jerusalem.
