Filed: 1974-04-22
Abstract: Rotary combustion engine comprises three combustion chambers formed by an eccentric rotor in which are three grooves housing spacers which press resiliently against a surrounding jacket which also rotates at the same speed, without causing braking by too high a pressure. The spacers have lateral sealing strips to seal off the combustion chambers. Two revolutions of the rotor produce induction, compression, power and exhaust strokes. One shaft is provided for transmission, and one for ignition contacts, water pump and dynamo. The jacket contains for each chamber two valves, a sparking plug, and inlet and exhaust ports ending in an annular channel of an outer housing. In the outer housing are a metal ring and three metal poles connected to the ht leads, providing ignition distribution.

The pinion intermeshes with the gear rim which is joined to the column.
Patent DE-2423955-A1 (DE)
Title: Vacuum dehydration of e.g. coffee extract - using electrical heating in a vacuum of 100-1000 microns mercury
Inventor: GELDER ARTHUR VAN
IPC: F26B5/04
Filed: 1974-05-15
Abstract: In a process for vacuum dehydration, in which a material borne in cell carriers is subjected to a vacuum of 100-1000 microns mercury in a chamber from which the water vapour is rapidly removed, the cell carriers each contain a large number of transversely arranged plates spaced apart. The plates are rigid and electrically conductive, and each is covered with an electrically insulating material. The plates are held apart by electrically conductive spacers, and the material to be treated, which is packed into the spaces between the plates, is heated when an electric current is passed through the plates, which then act as heat sources having a uniform thermal distribution over their entire surfaces. The process results in lower costs per unit of prod. and easier operation than induction heating techniques.
Patent DE-2427432-A1 (DE)
Title: Braking system for fast electric train - with regenerative and fail-safe mechanical braking in case of supply failure
Inventor: BARZ JUERGEN ING GRAD
IPC: B60L7/26
Filed: 1974-06-06
Abstract: The fast electric train is fitted with regenerative braking as the main braking system and with mechanical brakes for additional braking and for securing the train when stopped. If the electric supply fails then the vehicle batteries are not large enough to supply the field coils of the motors for regenerative braking. A fail-safe braking control is fitted which switches the mechanical braking to maximum effect when the supply fails, and which switches the function of the regenerative brakes to a back-up operation with the capacity of the batteries determining the amount of regenerative braking. A speed control is fitted which switches off the regenerative braking below a set value.
