Patent DE-3819623-A1 (DE)
Title: Vane-cell pump
Inventor: JURR RICHARD
IPC: F04C29/12
Filed: 1988-06-09
Abstract: In the case of a vane-cell pump, an outlet (10) is connected to the pump chamber (9b, 9c) via a plurality of connecting channels (11, 12, 13). These connecting channels (11, 12, 13) open into the pump chamber (9b, 9c) one after the other in the direction of rotation of the rotor (2) of the vane-cell pump and each have a non-return valve (14, 15, 16). Consequently, pressure medium which has already been slightly compressed can, with a slight back-pressure, leave the pump chamber (9b) via the first connecting channel (11) seen in the direction of rotation of the rotor (2) and an influx of air from the pump outlet (10) in the pump chamber (9c) is excluded. <IMAGE>

Title: Transmission of telephone cable parameters over lines - converts cable measured value into analog frequency within range below speech frequency
Inventor: VEMMER HELMUT DIPL ING
IPC: H04M3/28
Filed: 1989-07-11
Abstract: The transmission takes place irrespective of the telephone line engagement by calls. The respective cable measured value is converted into an analog frequency within a frequency range below that of the speech frequency. The signal of such frequency is fed into the cable speech line and simultaneously to one of several input in a number of multi-channel reception converters. The converters insulate the signal frequency from interferences by forming a mean value, possibly with continuous actualising, for storage. The reception converters are interrogated cyclically by an evaluation circuit, followed by switching over to the next input. USE/ADVANTAGE - For telephone cable protection, without need for special service core.

Title: Process and assembly for electrical desorption - and regeneration of carbon granules allowing redn. in energy consumption for desorption
Inventor: SCHREINER HERMANN PROF
IPC: C01B31/08
Filed: 1990-07-24
Abstract: Carbon granules are employed to absorb effluent gases and become satd. and must be replaced or regenerated. Novelty is that desorption and regeneration is effected by the transmission of electrical energy through the active carbon granules. The electrical energy is introduced in the carbon through two or three symmetrically distributed electrodes which pass direct current and alternating current between each other and the earthed granule container. Three alternating current electrode plates are arranged symmetrically to the desorption axis, such that the ratio of their distance from each other to the distance from the container wall is 1.7.
