4 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.

5 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 -

10 Albert, Wilhelm August Julius
SUBJECT AREA: Mining and extraction technology[br]b. 24 January 1787 Hannover, Germanyd. 4 July 1846 Clausthal, Harz, Germany[br]German mining official, successful applier of wire cable.[br]After studying law at the University of Göttingen, Albert turned to the mining industry and in 1806 started his career in mining administration in the Harz district, where he became Chief Inspector of mines thirty years later. His influence on the organization of the mining industry was considerable and he contributed valuable ideas for the development of mining technology. For example, he initiated experiments with Reichenbach's water-column pump in Harz when it had been working successfully in the transportation of brine in Bavaria, and he encouraged Dörell to work on his miner's elevator.The increasing depths of shafts in the Harz district brought problems with hoisting as the ropes became too heavy and tended to break. At the beginning of the nineteenth century, iron link chains replaced the hempen ropes which were expensive and wore out too quickly, especially in the wet conditions in the shafts. After he had experimented for six years using counterbalancing iron link chains, which broke too easily, in 1834 he conceived the idea of producing stranded cables from iron wires. Their breaking strength and flexibility depended greatly on the softness of the iron and the way of laying the strands. Albert produced the cable by attaching the wires to strings which he turned evenly; this method became known as "Albert lay". He was not the first to conceive the idea of metal cables: there exists evidence for such cables as far back as Pompeii; Leonardo da Vinci made sketches of cables made from brass wires; and in 1780 the French engineer Reignier applied iron cables for lightning conductors. The idea also developed in various other mining areas, but Albert cables were the first to gain rapidly direct common usage worldwide.[br]Bibliography1835, "Die Anfertigung von Treibseilen aus geflochtenem Eisendraht", Karstens Archiv 8: 418–28.Further ReadingK.Karmarsch, "W.A.J.Albert", Allgemeine deutsche Biographie 1:212–3.W.Bornhardt, 1934, W.A.J.Albert und die Erfindung der Eisendrahtseile, Berlin (a detailed description of his inventions, based on source material).C.Bartels, 1992, Vom frühneuzeitlichen Montangewerbe zur Bergbauindustrie, Bochum: Deut sches Bergbau-Museum (evaluates his achievements within the framework of technological development in the Harz mining industry).WKBiographical history of technology > Albert, Wilhelm August Julius

11 Curr, John
[br]b. 1756 Kyo, near Lanchester, or in Greenside, near Ryton-on-Tyne, Durham, Englandd. 27 January 1823 Sheffield, England[br]English coal-mine manager and engineer, inventor of flanged, cast-iron plate rails.[br]The son of a "coal viewer", Curr was brought up in the West Durham colliery district. In 1777 he went to the Duke of Norfolk's collieries at Sheffield, where in 1880 he was appointed Superintendent. There coal was conveyed underground in baskets on sledges: Curr replaced the wicker sledges with wheeled corves, i.e. small four-wheeled wooden wagons, running on "rail-roads" with cast-iron rails and hauled from the coal-face to the shaft bottom by horses. The rails employed hitherto had usually consisted of plates of iron, the flange being on the wheels of the wagon. Curr's new design involved flanges on the rails which guided the vehicles, the wheels of which were unflanged and could run on any hard surface. He appears to have left no precise record of the date that he did this, and surviving records have been interpreted as implying various dates between 1776 and 1787. In 1787 John Buddle paid tribute to the efficiency of the rails of Curr's type, which were first used for surface transport by Joseph Butler in 1788 at his iron furnace at Wingerworth near Chesterfield: their use was then promoted widely by Benjamin Outram, and they were adopted in many other English mines. They proved serviceable until the advent of locomotives demanded different rails.In 1788 Curr also developed a system for drawing a full corve up a mine shaft while lowering an empty one, with guides to separate them. At the surface the corves were automatically emptied by tipplers. Four years later he was awarded a patent for using double ropes for lifting heavier loads. As the weight of the rope itself became a considerable problem with the increasing depth of the shafts, Curr invented the flat hemp rope, patented in 1798, which consisted of several small round ropes stitched together and lapped upon itself in winding. It acted as a counterbalance and led to a reduction in the time and cost of hoisting: at the beginning of a run the loaded rope began to coil upon a small diameter, gradually increasing, while the unloaded rope began to coil off a large diameter, gradually decreasing.Curr's book The Coal Viewer (1797) is the earliest-known engineering work on railway track and it also contains the most elaborate description of a Newcomen pumping engine, at the highest state of its development. He became an acknowledged expert on construction of Newcomen-type atmospheric engines, and in 1792 he established a foundry to make parts for railways and engines.Because of the poor financial results of the Duke of Norfolk's collieries at the end of the century, Curr was dismissed in 1801 despite numerous inventions and improvements which he had introduced. After his dismissal, six more of his patents were concerned with rope-making: the one he gained in 1813 referred to the application of flat ropes to horse-gins and perpendicular drum-shafts of steam engines. Curr also introduced the use of inclined planes, where a descending train of full corves pulled up an empty one, and he was one of the pioneers employing fixed steam engines for hauling. He may have resided in France for some time before his death.[br]Bibliography1788. British patent no. 1,660 (guides in mine shafts).1789.
