2 Engerth, Wilhelm
[br]b. 26 May 1814 Pless, Prussian Silesia (now Poland)d. 4 September 1884 Baden, Austria[br]German engineer, designer of the Engerth articulated locomotive.[br]Engerth was Chairman of the judges for the Semmering Locomotive Trials, held in 1851 to find locomotives suitable for working the sharply curved and steeply graded section of the Vienna-Trieste railway that was being built over the Semmering Pass, the first of the transalpine main lines. When none of the four locomotives entered proved suitable, Engerth designed his own. Six coupled wheels were at the fore part of the locomotive, with the connecting rods driving the rear pair: at the back of the locomotive the frames of the tender were extended forward on either side of the firebox, the front wheels of the tender were ahead of it, and the two parts were connected by a spherical pivot ahead of these. Part of the locomotive's weight was carried by the tender portion, and the two pairs of tender wheels were coupled by rods and powered by a geared drive from the axle of the rear driving-wheels. The powered drive to the tender wheels proved a failure, but the remaining characteristics of the locomotive, namely short rigid wheel-base, large firebox, flexibility and good tracking on curves (as drawbar pull was close behind the driving axle), were sufficient for the type to be a success. It was used on many railways in Europe and examples in modified form were built in Spain as recently as 1956. Engerth became General Manager of the Austro-Hungarian State Railway Company and designed successful flood-prevention works on the Danube at Vienna.[br]Principal Honours find DistinctionsKnighted as Ritter von Engerth 1861.

3 уравнения справедливы для
Уравнения справедливы для -- These equations are valid for all positive values of g. Уравновешивать(ся) - to balance, to be in balance; to be balanced by, to be counteracted by, to be counterbalanced byFor a Ca:S mol ratio of two, the gain and loss in bed mass approximately balance, and these effects are ignored in the model.Under steady-state conditions, these inflows and outflows are in balance.The resulting horizontal couple is balanced by a vertical couple in the tie rods.The inhibition produced by azaserine is counteracted by performed purines.The reduction in total amount of RNA is counterbalanced by an increased rate of turnover in the remaining molecules.Русско-английский научно-технический словарь переводчика > уравнения справедливы для

4 Hackworth, Timothy
[br]b. 22 December 1786 Wylam, Northumberland, Englandd. 7 July 1850 Shildon, Co. Durham, England[br]English engineer, pioneer in construction and operation of steam locomotives.[br]Hackworth trained under his father, who was Foreman Blacksmith at Wylam colliery, and succeeded him upon his death in 1807. Between 1812 and 1816 he helped to build and maintain the Wylam locomotives under William Hedley. He then moved to Walbottle colliery, but during 1824 he took temporary charge of Robert Stephenson \& Co.'s works while George Stephenson was surveying the Liverpool \& Manchester Railway and Robert Stephenson was away in South America. In May 1825 Hackworth was appointed to the Stockton \& Darlington Railway (S \& DR) "to have superintendence of the permanent (i.e. stationary) and locomotive engines". He established the workshops at Shildon, and when the railway opened in September he became in effect the first locomotive superintendent of a railway company. From experience of operating Robert Stephenson \& Co.'s locomotives he was able to make many detail improvements, notably spring safety valves. In 1827 he designed and built the locomotive Royal George, with six wheels coupled and inverted vertical cylinders driving the rear pair. From the pistons, drive was direct by way of piston rods and connecting rods to crankpins on the wheels, the first instance of the use of this layout on a locomotive. Royal George was the most powerful and satisfactory locomotive on the S \& DR to date and was the forerunner of Hackworth's type of heavy-goods locomotive, which was built until the mid-1840s.For the Rainhill Trials in 1829 Hackworth built and entered the locomotive Sans Pareil, which was subsequently used on the Bol ton \& Leigh Railway and is now in the Science Museum, London. A working replica was built for the 150th anniversary of the Liverpool \& Manchester Railway in 1980. In 1833 a further agreement with the S \& DR enabled Hackworth, while remaining in charge of their locomotives, to set up a locomotive and engineering works on his own account. Its products eventually included locomotives for the London, Brighton \& South Coast and York, Newcastle \& Berwick Railways, as well as some of the earliest locomotives exported to Russia and Canada. Hackworth's son, John Wesley Hackworth, was also an engineer and invented the radial valve gear for steam engines that bears his name.[br]Further ReadingR.Young, 1975, Timothy Hackworth and the Locomotive, Shildon: Shildon "Stockton \& Darlington Railway" Silver Jubilee Committee; orig. pub. 1923, London (tends to emphasize Hackworth's achievements at the expense of other contemporary engineers).L.T.C.Rolt, 1960, George and Robert Stephenson, London: Longmans (describes much of Hackworth's work and is more objective).E.L.Ahrons, 1927, The British Steam Railway Locomotive 1825–1925, London: The Locomotive Publishing Co.PJGR
