1 Ilgner, Karl
SUBJECT AREA: Electricity[br]b. 27 July 1862 Neisse, Upper Silesia (now Nysa, Poland)d. 18 January 1921 Berthelsdorf, Silesia[br]German electrical engineer, inventor of a transformer for electromotors.[br]Ilgner graduated from the Gewerbeakademie (the forerunner of the Technical University) in Berlin. As the representative of an electric manufacturing company in Breslau (now Wroclaw, Poland) from 1897, he was confronted with the fact that there were no appropriate drives for hoisting-engines or rolling-plants in steelworks. Two problems prevented the use of high-capacity electric motors in the mining as well as in the iron and steel industry: the reactions of the motors on the circuit at the peak point of stress concentration; and the complicated handling of the control system which raised the risks regarding safety. Having previously been head of the department of electrical power transmission in Hannover, he was concerned with the development of low-speed direct-current motors powered by gas engines.It was Harry Ward Leonard's switchgear for direct-current motors (USA, 1891) that permitted sudden and exact changes in the speed and direction of rotation without causing power loss, as demonstrated in the driving of a rolling sidewalk at the Paris World Fair of 1900. Ilgner connected this switchgear to a large and heavy flywheel which accumulated the kinetic energy from the circuit in order to compensate shock loads. With this combination, electric motors did not need special circuits, which were still weak, because they were working continuously and were regulated individually, so that they could be used for driving hoisting-engines in mines, rolling-plants in steelworks or machinery for producing tools and paper. Ilgner thus made a notable advance in the general progress of electrification.His transformer for hoisting-engines was patented in 1901 and was commercially used inter alia by Siemens \& Halske of Berlin. Their first electrical hoisting-engine for the Zollern II/IV mine in Dortmund gained international reputation at the Düsseldorf exhibition of 1902, and is still preserved in situ in the original machine hall of the mine, which is now a national monument in Germany. Ilgner thereafter worked with several companies to pursue his conception, became a consulting engineer in Vienna and Breslau and had a government post after the First World War in Brussels and Berlin until he retired for health reasons in 1919.[br]Bibliography1901, DRP no. 138, 387 1903, "Der elektrische Antrieb von Reversier-Walzenstraßen", Stahl und Eisen 23:769– 71.Further ReadingW.Kroker, "Karl Ilgner", Neue Deutsche Biographie, Vol. X, pp. 134–5.

2 Koepe, Friedrich
SUBJECT AREA: Mining and extraction technology[br]b. 1 July 1835 Bergkamen, Westphalia, Germanyd. 12 September 1922 Bochum, Germany[br]German mining engineer, inventor of the friction winder for shaft hoisting.[br]After attending the School of Mines at Bochum, from 1862 he worked as an overseer in the coal-mining district of Ibbenbüren until he joined a mining company in the Ruhr area. There, as head of the machine shop, he was mainly concerned with sinking new shafts. In 1873 he became the Technical Director of the Hannover mine, near Bochum, which belonged to Krupp. When the shaft hoisting was to be extended to a lower level Koepe conceived the idea of applying a friction winder to the hoist instead of a drum, in order to save weight and costs. His method involved the use of an endless rope to which the cages were fixed without a safety catch. The rope passed over pulleys instead of coiling and uncoiling on a drum, and he consequently proposed to have the motor erected on top of the shaft rather than beside it, as had been the practice until then.Koepe's innovation turned out to be highly effective for hoisting heavy loads from deep shafts and was still popular in many countries in the 1990s, although the Krupp company did not accept it for a long time. He had severe personal problems with the company, and as Krupp refused to have his system patented he had to take it out in his own name in 1877. However, Krupp did not pay for the extension of the patent, nor did they pass the dossiers over to him, so the patent expired two years later. It was not until 1888 that a hoisting engine equipped with a friction winder was erected for the first time in a head gear, above the new Hannover II shaft. The following year Koepe left the Krupp company and settled as a freelance consulting engineer in Bochum; he was successful in having his system introduced by other mining companies. Ironi-cally, in 1948 the world's first four-rope winding, based on his system, was installed at the Hannover mine.[br]Further ReadingFor detailed biographical information and an assessment of his technological achievements see: H.Arnold and W.Kroker, 1977, "100 Jahre Schachtförderung nach dem System Koepe", Der Anschnitt 29:235–42.F.Lange, 1952, Die Vierseilförderung, Essen.WK -
