Frequency regulation circuit with sweep circuit

Claim 1

IN A CIRCUIT FOR THE AUTOMATIC REGULATION OF THE FREQUENCY OF A VARIABLE OSCILLATOR TO BE STABILIZED, UTILIZING A REACTANCE CIRCUIT IN THE VARIABLE OSCILLATOR CIRCUIT, WHICH REACTANCE CIRCUIT CONTAINS A VOLTAGE-CONTROLLED CAPACITANCE DIODE CONNECTED IN PARALLEL WITH THE OSCILLATORY CIRCUIT AND WHICH IS CONTROLLED BY A FREQUENCY REGULATING VOLTAGE OBTAINED FROM A PHASE DISCRIMINATOR, IN CONJUNCTION WITH A WOBBLE VOLTAGE, THE COMBINATION OF AN RC-GENERATOR FOR THE GENERATION OF THE WOBBLE VOLTAGE ARRANGED IN A CIRCUIT BRANCH EXTENDING IN PARALLEL TO THE REGULATION PATH, THE OUTPUT OF THE PHASE DISCRIMINATOR BEING CONNECTED OVER THE REGULATING LINE, AND THE OUTPUT OF THE RCGENERATOR BEING CONNECTED OVER RESPECTIVE CAPACITANCES WITH RESPECTIVE DIFFERENT POLES OF THE CAPACITANCE DIODE OF THE REACTANCE CIRCUIT, THE POLE OF THE CAPACITANCE DIODE CONNECTED TO THE OUTPUT OF THE RC-GENERATOR BEING CONNECTED WITH A DIRECT CURRENT SOUCE OF CONSTANT VOLTAGES FOR THE FEEDING THERETO OF A BLOCKING VOLTAGE, THE PHASE DISCRIMINATOR BEING CONNECTED WITH THE RC-GENERATOR AT SUCH A POINT IN THE CIRCUIT THAT ON OCCURRENCE OF A FREQUENCY REGULATING VOLTAGE A FEED-BACK RESULTS AT THE RCGENERATOR WHICH TERMINATES THE OSCILLATORY STATE OF THE RC-GENERATOR.
