Patent DE-3601528-A1 (DE)
Title: Internal combustion piston engine, in-line engine with variable compression ratio
Inventor: SCHWARZ WOLFGANG
IPC: F02B75/04
Filed: 1986-01-20
Abstract: The variable compression ratio is obtained by raising and lowering the crankshaft. This occurs due to the fact that the crankshaft is eccentrically supported in the engine block by means of eccentric bushes or eccentric rings arranged between blind bore and bushes, which rings are fixed to one another and rotated together by way of an adjusting mechanism. The common rotation of the eccentrics results in an enlargement or reduction of the combustion space, depending on the direction of rotation, and hence a reduction or increase of the compression ratio.

Title: Circuit arrangement for an electronic ripple-control receiver
Inventor: MUELLER BEAT DIPL ING
IPC: H04B3/54
Filed: 1986-02-14
Abstract: The circuit arrangement has an evaluation section (26) for evaluating the received remote-control signals, switching devices (35) which can be controlled by the evaluation section, and a switching energy store (44), which is allocated to the switching devices in order to operate them. The evaluation section (26) is formed by a microcomputer and a circuit is provided for monitoring the energy contents of the switching energy store (44), which circuit has a reference element (52) and a switching element (56) and delays the driving of the switching devices (35), if the energy contents are less than a limiting value, until this limiting value is reached again. This delay is effected by temporarily storing the received remote-control signals in the microcomputer (26). In consequence, a plurality of switching devices can be operated reliably by one ripple-control receiver without it being necessary to increase the energy contents of the switching energy store or the power of the power supply section in a corresponding manner. <IMAGE>

Title: Method for producing thermal energy
Inventor: CESLIK ALFONS
IPC: F24V30/00
Filed: 1987-10-19
Abstract: A method for producing thermal energy by splitting water and the hydrogen thereby produced is distinguished according to the invention in that a temperature generator is used to generate a constant high-temperature zone which is thermally isolated from the outside, in that water vapour is introduced into the high-temperature zone, and in that all the hydrogen released by thermal splitting of the water vapour is burned directly in the high-temperature zone with the oxygen released during splitting. In this process, at most so much water vapour is applied or useful thermal energy is dissipated that at least a temperature level sufficient for thermal splitting is maintained in the high-temperature zone. This method can be used to generate virtually any quantity of heat in an exceptionally economic and environmentally friendly way in conjunction with reduced use of classical energy carriers.
