Patent DE-3009355-A1 (DE)
Inventor: UEBEL HELMUT DIPL ING
IPC: G06F11/16
Filed: 1980-03-12
Abstract: In order to reduce the computer capacity needed for the data exchange between the computers in a redundant computer system with two single computers (R1, R2) and a number of memories (E1, E2, A1, A2), in which the individual computers work out all results in parallel and in which the processing results are tested by data comparison, a data reduction is effected. For this purpose, the output registers (A1, A2) of the two computers (R1, R2) are connected to feedback-type shift registers (SR1, SR2) via lines (1, 2) via which they serially obtain the data worked out by the respective computer. The feedback-type shift registers carry out a modulo-2 addition of the data received and thus effect a data reduction. With a Hamming distance of H=4, data volumes of over 32,000 bits can thus be saved by means of one 16-bit shift register. After up to 32,000 bits have been input, the comparison is effected between the 16-bit words of the shift registers which are interrogated for this purpose by the computers via data lines (3, 4). <IMAGE>

Title: Precision measurement of parameter values - uses alternate heating with measurement and reference parameters
Inventor: GERMER HORST PROF DR ING
IPC: G01R19/02
Filed: 1980-04-02
Abstract: The arrangement for precision measurement of the effective values of electrical parameters involves alternate application of the measurement parameter and a reference parameter to a thermal transducer. The ratio of the two parameters is varied until their thermal effects are equal. The reference parameter (Y) has a constant value. The measurement parameter (X(t)) is amplified or attenuated in an input stage (1). The degree of amplification or attenuation is varied until the variations in output signal V(t) with changeover of the switch (6) providing the thermal transducer (3) input are nulled. The reference parameter value is chosen so that the thermal transducer operates in its region of maximum sensitivity.

Title: Rotating mechanism for engine or pump - has oscillating segments in working space forming variable volume rotating chambers
Inventor: FIEDLER GUENTER ING GRAD
IPC: F02B53/00
Filed: 1980-09-23
Abstract: The machine has a circular stator with an annular working chamber within it. A rotor (1b) on a shaft (1a) revolves within it. The rotor has two pinions (2a,2b) on it which mesh with a stationary gear (3) on the stator. They thus travel with the rotor and at the same time turn on their own axes. Each pinion has a crank drive (4b) to a segment (5a,5b) which is thus carried with the rotor while oscillating relatively to it. The segments have projecting piston lugs which divide the annular working chamber into sections varying in volume. Expansion and compression occur at fixed points within the stator.

Patent DE-3105874-A1 (DE)
Inventor: FAUCK GERHARD
IPC: B60T8/18
Filed: 1981-02-18
Abstract: A vehicle load controlled fluid brake pressure regulator having a relay valve portion that includes a variable area differential relay valve piston, the effective area of which varies in accordance with different load conditions. A control portion of the brake pressure regulator includes a stepped control piston having two piston faces subject to the load dependent pressure of separate air springs of the vehicle, so as to be axially displaceable for different load conditions. Oppositely inclined control surfaces of two cam members carried by the control piston translate the axial position of the control piston to the relay valve piston via an actuator stem. One cam member is axially adjustable relative to the other, so as to cause the hollow or low point of the cam profile formed by the inclined control surfaces to engage the actuator stem for any desired "empty" load setting of the relay valve portion.

Patent DE-3113832-A1 (DE)
Title: Time switching apparatus
Inventor: REICH STEFAN
IPC: H01H43/00
Filed: 1981-04-06
Abstract: A time switching apparatus having a delay mechanism which switches on an electrical load and switches it off again automatically after a set time interval, characterised in that the disconnection can also be effected manually at any time. The invention relates to:   A) both light switches in stairwells, garages and the like ("stairwell light time switches"), and B) light switches in rooms through which people pass in flats (apartments), commercial premises, hospitals, hotels etc. (hallways, cellars, toilets, corridors, store rooms etc.).  The invention is used to save electrical power. With respect to A), in order to prevent the stairwell lighting being on for longer than necessary, it can also be switched off at each of the on switches before the automatic switching-off system comes into operation. With respect to B), after passing through a hallway, a corridor or after leaving a store room etc., people often forget to switch off the light. People are frequently also prevented from doing so because, for example on leaving the cellar, they do not have any free hands. Unnecessary electrical power consumption can be avoided by means of a built-in time switch.
