Title: Video amplifier black value error compensation - adds interference signals to video signal with amplitude and polarity for error compensation in front of amplifier
Inventor: SCHNEIDER HANS DIETER
IPC: H04N5/18
Filed: 1973-10-31
Abstract: The system is intended for video amplifiers with clamping stages. Interference signals caused by power fluctuations due to signal voltage drop caused by internal resistance across the amplifier supply voltage source are added to the video signal with such polarity and amplitude, that they are compensated in front of amplifier clamping stages. Preferably the video amplifier is of a differential type, and the video signal is applied to its one input. Its inverting input is connected through a capacitor to an adjustable part of the supply voltage, and the amplifier output is connected to the clamping stage. The inverting mixing of the interference signal is front of the amplifier clamping stage removes modulation harmful to the black value.

Title: Logic circuit for AC voltage input signals - has input transformer with retified secondary outputs and transistor blocking oscillator
Inventor: LOTZ ALFRED
IPC: H03K19/082
Filed: 1975-01-28
Abstract: The rectified input signals form individual control potentials for a transistor blocking oscillator with a feedback transformer. The pulse voltage of the blocking oscillator is applied to the output through an amplifier in the feedback transformer secondary circuit. In order to convert static signals into a dynamic signal, a static zero signal lowers the base potential of the blocking oscillator transistor to the reference potential. The supply voltage is applied to this transistor through a second static input. The reference potential wire forms a third input, and a transistor emitter the fourth input. The blocking oscillator output voltage is rectified (V7) and trips a following emitter stage, consisting of a transistor (V5) and a collector resistor (R6) shunted by a diode (V8), from its blocked to saturated state.
