Voltage tuned oscillator

Claim 1

AN OSCILLATOR CIRCUIT COMPRISING A RESONANT CIRCUIT FOR DEVELOPING ALTERNATING SIGNALS AND INCLUDING A FIRST INDUCTOR AND FIRST AND SECOND DIODES HAVING A CAPACITANCE WHICH VARIES NONLINEARLY WITH VARIATION OF AN APPLIED VOLTAGE, SAID FIRST AND SECOND DIODES COUPLED IN SERIES TO FORM A REACTANCE CIRCUIT, SAID REACTANCE CIRCUIT COUPLED BETWEEN ONE END OF SAID FIRST INDUCTOR AND A SOURCE OF POTENTIAL, THE OTHER END OF SAID FIRST INDUCTOR BEING COUPLED TO SAID SOURCE OF POTENTIAL, AN AMPLIFIER CIRCUIT COUPLED TO SAID FIRST INDUCTOR, A FEEDBACK COIL COUPLED BETWEEN SAID AMPLIFIER CIRCUIT AND SAID SOURCE OF POTENTIAL AND MUTUALLY COUPLED TO SAID FIRST INDUCTOR, A SECOND INDUCTOR HAVING ONE END COUPLED TO SAID FIRST INDUCTOR AND MUTUALLY COUPLED TO SAID FIRST INDUCTOR, RECTIFIER MEANS COUPLED BETWEEN THE OTHER END OF SAID SECOND INDUCTOR AND SAID SOURCE OF POTENTIAL, AND CONTROL MEANS COUPLED BETWEEN SAID RECTIFIER MEANS AND SAID SOURCE OF POTENTIAL AND TO SAID REACTANCE CIRCUIT FOR SELECTIVELY VARYING THE CAPACITANCE THEREOF TO VARY THE FREQUENCY OF SAID OSCILLATOR.
