Title: Low temp. waste heat utilisation - uses ground heat, earth heat storage ability and deep long term storage
Inventor: KRIEB FRANZ KARL
IPC: F24D11/02
Filed: 1980-02-16
Abstract: The system utilises and stores low temp. waste heat from power stations and industrial plants. The heat may be used directly, or after further heating by heat pumps, to heat rooms and water, esp. in multi-storey buildings, and swimming pools. Excess heat, and any other waste heat, is stored in a storage medium at great depth, or in the ground itself. When withdrawing heat, the medium is cooled to below its freezing point, utilising any latent heat, and heat is withdrawn from the surrounding ground, which is at a higher temp. After withdrawal, the storage medium is heated by warmth from the ground and solar radiation. Excess heat from the rooms is fed via a cooling system into a long term store.

Title: Motor vehicle engine fuel economiser - has carburettor main passage with stop member switched into open or closed position by appropriate signal
Inventor: ALBRECHT FRANZ
IPC: F02M3/045
Filed: 1980-03-26
Abstract: The main passage of the carburretor supplies the engine with fuel even in idle run. The main passage has a stop member which can be closed or opened by a mechanical, pneumatic, hydraulic, or electric signal. A sensor detects the operational position of the accelerator pedal. In the pedal rest position the sensor transmits a switch-off signal for the engine idle run speed, while in the pedal active region for motor speed above the idle run it transmits a switch-on signal. A second sensor detects the speed of the engine. It transmits a switch-on signal in the lower speed range from the rest value up to a certain intermediate speed value, slightly above the idle run speed. In the speed range above the intermediate value it transmits a switch-off signal. Appropriate signal lines with and/or without signal transducers lead from the first sensor for pedal operating position and the second sensor for speed to the stop member with an OR-logic connection of the switch-on signals of both sensors.

Title: Final-drive assembly for motor vehicles equipped with fully lined disc brakes
Inventor: KLAUE HERMANN DR ING
IPC: B60T1/06
Filed: 1981-04-13
Abstract: The final-drive assembly of the invention has a differential, the differential cage of which receives the brake actuating force in that its drive bevel gears are connected non-positively and axially to the drive shafts and the rear sides of the latter lying opposite their teeth are supported by axial bearings, in that two one-piece, radially ribbed brake housings which comprise the universal joints with their flange extensions and are fixed on the final-drive assembly flanges on each side of the final-drive assembly are arranged on their outsides remote from the final-drive assembly housing, and that actuators, each comprising two stepped rings and fixed to the said final-drive assembly housing, are arranged between brake-housing friction surfaces and final-drive assembly housing, which said actuators act on two brake discs which are fixed in the circumferential direction, are axially movable and carry the brake linings. By means of these measures a low-wear, maintenance-free brake is created because the friction heat of the brake housings rotating in the air flow, produced in braking, is dissipated to the air mainly by convection without the drive parts becoming overheated.   <IMAGE>

Title: Injection system on an internal combustion engine
Inventor: GENTSCHEFF JORDAN DIPL ING
IPC: F02M59/26
Filed: 1982-04-22
Abstract: An injection system on an internal combustion engine with an injection pump for supplying an injection valve with fuel, especially at high pressure, is to be designed so that optimisation of the fuel consumption is possible in all load ranges. For this purpose the pump piston of the injection pump is designed in such a way that the two control edges, which determine the start and the end of injection respectively, can be rotated in opposition to one another. In addition a separate rotating mechanism with open loop and closed loop control elements is assigned to each of the two control edges, by means of which either a joint or independent rotation of the two control edges is possible. By means of these control edges a feed duct and a relief duct can be opened and closed, which ducts run between a pump pressure chamber and an intake and return flow chamber connected to a fuel supply. The feed duct is at the same time assigned only to the upper control edge and can be opened and closed by this. The relief duct, on the other hand, is assigned to the lower control edge, can be opened only by this and branches off from the pump pressure chamber above the pump piston TDC position.

Title: Electronic flash apparatus having a voltage converter
Inventor: BEUTER BERND DIPL ING
IPC: H05B41/32
Filed: 1982-07-03
Abstract: A circuit arrangement of a flyback converter for an electronic flash apparatus is specified, in which a converter transformer (Tr) without a feedback winding is used. The phase shift required for the feedback is produced by a second transistor (T2) which is complementary to the converter transistor (T1). In consequence, the efficiency of the flyback converter can be improved. In addition, the control power which is required to switch the converter off is reduced, as a result of which the control of the converter is simplified so that, for example, it can be driven at low power by an integrated circuit. <IMAGE>
