Title: Reciprocating piston internal combustion engine with rotating cylinders
Inventor: SCHUELER KARL-LUDWIG
IPC: F01B13/06
Filed: 1982-10-09
Abstract: In the reciprocating piston internal combustion engine described the cylinders rotate against the crankshaft so that one working cycle is obtained for one crankshaft revolution per cylinder. It is possible to work with a lower speed of rotation. This reciprocating piston internal combustion engine completely replaces multi-cylinder reciprocating piston internal combustion engines like those used in motor vehicles and furthermore has the advantage of fewer parts, less maintenance (no adjustment of valves, for example) and a lower speed of rotation.

Title: Spring energy store
Inventor: ILSEMANN BERNHARD
IPC: F16H48/30
Filed: 1982-10-12
Abstract: The invention relates to a double-acting spring energy store with two functionally independent storage springs for a switching device for the torsional coupling and decoupling of two rotating components provided with toothing or the like, in particular for connecting and disconnecting a differential lock or a final drive of a motor vehicle, in which switching device a sliding sleeve or the like is engaged and disengaged by swivelling an actuating lever with the interposition of the spring energy store, of a force transmission member transmitting tensile and compressive forces and of a lever arrangement. When the actuating lever is swivelled in one switching direction, only one storage spring is tensioned and, when the actuating lever is swivelled in the other switching direction, only the other storage spring is tensioned, while the other storage spring in each case is deflected simultaneously but without tension, with the result that, during all the switching actuations, only one spring is operative in each case and no return springs or the like have to be overcome. <IMAGE>

Title: Process and device for filtering dust-laden dirty gases, in particular hot metallurgical exhaust gases
Inventor: EISENBARTH MANFRED ING GRAD
IPC: B01D46/00
Filed: 1983-05-05
Abstract: In such a process for filtering dust-laden dirty gases, the dirty gas is led through dust-removing filter chambers and clean gas is then led in countercurrent through filter chambers to be cleaned. Filling a rectangular floor space with filter elements arranged in rows is unfavourable with respect to the flow-through of dirty gas. The dust collection bunkers arranged below each filter chamber and thus their dust discharge devices are subjected to relatively low loads, so that the efficiency of dust removal and the loading of the devices are each assessed unfavourably. In order to achieve high gas throughput with high filter efficiency and short down times for the cleaning apparatuses, it is proposed that the dirty gas is fed radially at the periphery in a rotating circular zone system, is led from the inlet into divided, separating dirty gas part-streams over a part of the periphery, that the clean gas streams from the individual filter zones are collected in a central clean gas shaft and that a continuous clean gas part-stream is led off from the central clean gas shaft at the periphery roughly opposite to the feed of the dirty gas and is led through a cleaning zone and then returned into the dirty gas stream and that the dust is discharged at a peripheral point, at most at two further peripheral points. <IMAGE>
