Title: Compact circuit for kilowatt-hour meter - has mains voltage variation compensation in generation of stepper motor pulses
Inventor: KUNDISCH HEINRICH
IPC: G01R21/00
Filed: 1980-05-19
Abstract: The circuit for a kilowatt-hour meter drives a stepper motor which operates a counter wheel assembly via a reduction gear. Pulses are produced by a flip-flop stage driven via an amplifier and rectifier circuit according to the load current flowing in a resistor (R1). Rhw meter is very compact, insensitive to vibrations, and economical to produce. A transistor (T1), resistor (R11), diode (D1) circuit permits only voltages proportional to the current in the sensing resistor (R1) to be processed. Another circuit section (D5,C6,R13,C7,R14 R15,R16,V4,R17,R19) passes a direct voltage proportional to the mains voltage variation to the flip-flop. This has the effect that for mains voltage variations of a correspondingly larger number of pulses is output from the flip-flop and vice-versa vice-versa.

Title: Telephone exchange with centralised control - uses parameter store to supply sub-programme addresses depending on required programme steps
Inventor: SCHIMMER ADOLF
IPC: H04Q3/545
Filed: 1980-12-19
Abstract: The telephone exchange with centralised control uses a parameter memory (FSP) which contains the addresses of a sub-programme in their sequence of operation. The parameter store (FSP) is divided into a number of storage regions corresponding to the changes in state effected by the switching operations, each with one output state and several end states. A further memory (VSP) storing the branching of the programme allows one of the possible successive junction steps to be selected in dependence on the actual detected change of state. The commands are read-out from the parameter store (FSP) one after the other, to allow the sub-programme for effecting the individual programme steps read-out from the programme store.
Patent DE-3104902-A1 (DE)
Title: Active media-free control surface
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: G01C19/02
Filed: 1981-02-11
Abstract: The known biaxial gyro control surface, in which A-A is perpendicular to the effective torque decoupling axis N-N, has been described such that, for example, on the four-gyro type, N-N passes through the centres of gravity of the two gyros supplying the instantaneous maximum torque. In the case of the three-gyro control surface, N-N passes through the centre of gravity of just one gyro instantaneously supplying maximum torque. These two statements define the construction and mode of operation of the biaxial type. Using this as a machine and vehicle drive by installation in a planetary gear unit, a reversal in the direction of rotation without stopping the input is interpreted at the output with a frictionally reversible mechanism, it also being possible for the output G-G to be shifted perpendicularly to N-N. New types of industrial drives with reversal without stopping the input and new types of motor vehicle rear axles with reversal without a reversing clutch and with inertial braking are derived therefrom.
