Title: Induction motor stator voltage controller - matches applied voltage to torque demand on rotor using discriminator to check frequency of coupled HF generator
Inventor: PARKER LOUIS W
IPC: H02P23/00
Filed: 1978-06-03
Abstract: The applied stator voltage is adjusted in response to changing load demand so that, at low loads, motor iron and copper losses are reduced. A typical application is to lifting machines. Rotor speed is given by a coupled h.f. generator whose output frequency is checked by a discriminator. Falling frequency indicates rising slip, and hence torque, and a slip proportional d.c. voltage is fed to an oscillator. The latter controls the triggering of a triac in the motor supply, thus regulating the voltage applied to the motor winding to match the torque demand.

Title: Control circuit including several processors - establishes synchronisation by using coincidence elements and comparators
Inventor: VETTER MICHAEL DIPL ING
IPC: G06F11/18
Filed: 1979-08-01
Abstract: This redundant control-check circuit includes several independent processors each with its own asynchronous clock, yet achieving adequate synchronisation. The output elements produce an output only after a predetermined number of equal input signals. As these output signals are returned to the processors, differences in the clock frequencies are equalised and the processors are synchronised. These output signals are therefore used to check for errors, to synchronise the processors and control some magnetic valve etc. Two processors processing identical data according to matching programs are linked via output and input busses to outout and input stores whose contents are used for checking and synchronisation via coincidence devices and comparators.

Title: Common line telephone with inter and exchange dialling - has coupling units setting transmission level automatically to suit type of call
Inventor: DUMKE DIETMAR ING GRAD
IPC: H04Q5/02
Filed: 1979-09-28
Abstract: A group party line telephone system is divided into a number of sections (LA1,LA2,...), cascaded by coupling units (KU12,KU23,...) with repeaters (VE12,23,...) and dialling extension units (KE12,23,...). A subscriber (TLN) has access to the line via his subscriber unit (U11,...) and transformer (LU11,...). One call at a time can be dialled between subscribers in the same section without involving the coupling units. A subscriber (TLN1x) in one section (LA1) can call a number (TLN21) in another (LA2) by dialling extra digits. These set an attenuator in his own unit (U1x) and activate the coupling unit (KU12), which passes on the extra digits to show which section the call is from. These then set an attenuator in the called subscriber's unit (U21). Transmission level both ways is thus set to suit the type of call.

Patent DE-2948787-A1 (DE)
Inventor: WEIHRICH GEORG DR ING
IPC: H05B7/144
Filed: 1979-12-04
Abstract: An impedance controller is used for controlling electrode-to-bath spacing in an arc furnace. Measured quantities proportional to the electrode voltage and the electrode current are determined and an actual impedance value is formed from the measured values by means of a divider. The actual impedance value is compared with a predeterminable desired impedance value to derive a control signal. If in the event of a short circuit, the actual impedance value reaches a predetermined lower limit, a switching element sets into the controller a signal causing full drive, so that the electrodes are raised at maximum velocity. If the sum of the two measurement quantities becomes zero, the output of the controller is cut off.
