Title: External compression IC engine - has compression of fuel mixt. performed outside engine
Inventor: SUESS WINFRIED
IPC: F02B37/00
Filed: 1975-11-15
Abstract: The compression of the fuel mixture is done externally and not in the combustion chamber as by conventional engines. The advantage claimed is that the compression ratio can be reduced without considerably effecting the engine performance. The output loss is compensated by the fact that the engine consumes less energy in not having to compress the fuel mixture. No specification details are given. The exhaust gases are used to turn a turbine which compresses the combustion air before being introduced into the combustion chamber.

Patent DE-2642565-A1 (DE)
Inventor: EISERMANN ARMIN
IPC: G07B15/02
Filed: 1976-09-22
Abstract: In this entry-monitoring system, the possibility of use without the use of personnel is considerably extended. When a person inserts the data carrier into the monitoring system, he need no longer pay in the full, otherwise customary amount, in order to initiate the functioning of the monitoring system, for example to lift the entry barrier of a swimming pool, but only the difference amount. In this case, the monitoring system is designed so that it indicates this difference amount. The size of this difference amount can also be varied by encoding the data carrier, so that extremely exact grading is possible within the preferred group of people. A particular group of people can thus initiate the function of the monitoring system under preferred conditions. This design can be used for vending machines or self-service machines of the most diverse type.
