Patent DE-3111178-A1 (DE)
Title: Supplementary control gear for variable-power engines
Inventor: WINKLEMANN SIEGFRIED ING GRAD
IPC: B23Q5/12
Filed: 1981-03-21
Abstract: An engine which can be controlled to give a constant output power is supplemented by a supplementary control gear flanged directly to it. In normal operation, this transmits the constant nominal power directly. When the speed range which can be covered by the engine alone is departed from, a variable speed gear built into the supplementary control gear is connected up. This compensates the speed drop to an appropriate degree and keeps the power constant in a larger range. The casing surrounds both a releasable shaft coupling, the output shaft with a common mounting for the latter and the variable speed gear and its control elements and permits the use of higher speeds without overstressing the engine mounts. Normally there is no need for a belt drive between the engine and the supplementary control gear and the design process is considerably simplified, no longer requiring a separate foundation and allowing higher efficiencies.
Patent DE-3116569-A1 (DE)
Title: Shearer drum for a winning machine in mining
Inventor: BEST GERD
IPC: E21C25/10
Filed: 1981-04-25
Abstract: The invention relates to a shearer drum for a winning machine in mining, in particular for underground coal mining. There is the problem here that the delivery segment wears relatively quickly. Water channels can be scoured free due to the wear, as a result of which spray liquid can come out without being used. This leads to the spray nozzles no longer functioning, because water seeks the route of least resistance. The invention proposes a measure for disengaging the worn part of the delivery segment from the spray-liquid feed by a shut-off member.

Title: Fuel injection pump for internal combustion engines
Inventor: FAUPEL WERNER
IPC: F02D1/18
Filed: 1981-12-05
Abstract: A fuel injection pump for internal combustion engines is proposed, which is provided with an adjusting piston (3) adjustable by means of a pump (6) delivering fluid in a manner proportional to the speed against a return force (5) for the purpose of adjusting the start of injection, and with a pressure control valve (14), which controls a fuel pressure proportional to the speed. A pressure maintaining valve (22), which above the operating temperature of the internal combustion engine is kept in the open position by an element (41, 42) operating as a function of the temperature, is arranged in series downstream of the pressure control valve (14). When the internal combustion engine is started below the operating temperature the closed pressure maintaining valve (22) causes an increase in the fuel pressure on the adjusting piston (3) in the working chamber (4), as a result of which the adjusting piston (3) is displaced more strongly in the direction of advanced injection until the pressure retaining valve (22) opens once a predetermined pump speed and/or temperature is reached and the pressure control valve (14) assumes its normal function of controlling the start of injection as a function of the pump speed. <IMAGE>
