Title: Pulse monitor detects missing input pulses reliability - by comparing square wave inputs and outputs of two square wave generators
Inventor: DOLCH KLAUS DIPL ING
IPC: G05B23/02
Filed: 1974-08-21
Abstract: The pulse monitor has its periodic input pulses (T) passed to the input of a flip-flop frequency divider (FF) coupled to the inputs of two identical square wave generators (A, B) (to one via an inverter (J1). The frequencies of the generators are related to the flip-flop's square wave output by specified inequalities. The input and output square waves to the generators are passed to an evaluator that compares the period and/or the slopes of these signals and triggers an alarm if the numbers of periods and/or slopes are not equal. The advantage lies in the reliability of detecting a missing input pulse.

Title: Duplicated power supply for essential loads - using identical voltage sources with semiconductor switching connects highest supply voltage to load
Inventor: MAIER KLAUS ING GRAD
IPC: H02J9/06
Filed: 1975-07-16
Abstract: The application is to the supply of power to local circuits in telephone exchanges. The system uses identical voltage sources (U1, U2) feeding a common load (V). Each line to the load contains a semiconductor element (D1, D2), typically a diode or transistor, thus permitting only the highest voltage source to provide power. As the sources are nominally identical power will be drawn alternately in a semi random manner from both, but should one fail the blocking action of the series semiconductor will prevent an overload on the remaining healthy source due to the low impedance of thr failed one. Lower forward resistances can be achieved by employing transistors in parallel as the reverse blocking elements. The whole circuit may be of thin or thick film integrated circuit type.
