Title: Camshaft control device
Inventor: KNUEFELMANN MANFRED
IPC: F01L1/344
Filed: 1982-03-25
Abstract: A camshaft control device for angular adjustment as a function of speed of rotation and load of at least one camshaft of an internal combustion engine. The technical problem resides in the adaptation of the camshaft control device to the conditions of a hydraulic drive. An ignition pulse computer (13) which is controlled by a toothed ring emits tooth pulses and reference pulses. An address counter (19) provides address signals which correspond to the respective angular position of the crankshaft (2). A desired value memory (20), driven by the address signals, outputs desired value signals for the camshaft adjustment. The desired value signal and an actual value signal of an actual value signal generator (34) are present at a differential circuit (33) of an adjustment control circuit (29, 30) as comparison signals and the differential circuit outputs control signals for an adjustment in a positive or negative direction. The control signals control valves (37) for the pressure medium circuit of a double-acting hydraulic control element (43) which adjusts the sheath (49) on the camshaft (6) in a force-fitting manner. <IMAGE>

Title: Low-pressure diesel engine with rotary swivel supercharger
Inventor: KICKBUSCH ERNST DIPL ING
IPC: F02B3/06
Filed: 1982-10-05
Abstract: A low-pressure diesel engine, particularly for powering a passenger motor vehicle, is proposed in which the maximum combustion pressures do not greatly exceed those of spark ignition engines and combustion temperatures over wide ranges are still lower than those in the spark ignition process, so that when used on existing models of this type the engine output can be increased without greater material stresses.   The proposal is based on the combination of a diesel engine with a rotary swivel supercharger according to European Patent 0012329, the advantages of this device being retained: greatly reduced fuel requirement, particularly in the partial load range, engine characteristic approximating to the ideal tractive force hyperbola, low speed of rotation, reduced noise, fewer toxic exhaust gases. Use of a Fottinger converter as sole transmission is possible for passenger motor vehicles - even in reverse drive. In order to achieve the object of the invention the compression ratio is reduced in comparison to that of a naturally aspirated engine on the diesel principle to such an extent that ignition of the injected fuel would not take place and the necessary ignition temperature is ensured by heating of the charging air by the corresponding amount. The heating is preferably performed by a flame and its hot combustion gases in the charging air flow. Variants, for example use of electrical energy in any form, are possible. The invention is also applicable to 2-stroke engines. The heating of the charging air... Original abstract incomplete.

Title: Circuit arrangement for a small dial-up PBX system with exchange traffic and an enquiry call facility
Inventor: ALTENDORFER ALOIS
IPC: H04M3/58
Filed: 1983-03-23
Abstract: The switching matrix device is constructed from integrated selector components. At its outputs, alongside the subscriber stations or forwarding connection lines, central devices are connected to connection points which are not occupied by subscriber stations. These devices serve primarily to evaluate and generate audible tones. Furthermore, a resistor is connected to a connection point which is not occupied by a subscriber station. A speech connection is thus terminated in relation to the forwarding lines in the enquiry call condition and the subscriber connection line is terminated in the pause conditions temporarily occurring at the start of an occupancy. This can also be carried out in similar fashion for the internal connections. Due to these terminal impedances which are effective in specific call phases, the howl, for example, of amplifiers connected in the respective transmission path is prevented.
