Crystal oscillator frequency stabilization system

Claim 1

AN ELECTRONIC OSCILLATOR STABLIZATION SYTEM FOR PROVIDING AN OUTPUT SIGNAL HAVING A HIGH DEGREE OF FREQUENCY AND PHASE STABILITY COMPRISING: A HIGH QUALITY CRYSTAL CONTROLLED TRANSISTOR OSCILLATOR MEANS HAVING OUTPUT MEANS FOR PROVIDING A FREQUENCY CONTROLLED OUTPUT SIGNAL, AND HAVING INPUT MEANS FOR RECEIVING A SIGNAL FOR REGULATING A SOLID STATE VARACTOR DIODE ELEMENT WHICH COMPRISES A VERNIER FREQUENCY CONTROL ELEMENT IN SAID OSCILLATOR MEANS; AN ELECTRICAL ATTENUATION MEANS HAVING INPUT AND OUTPUT TERMINAL MEANS, SAID INPUT TERMINAL MEANS BEING COUPLED TO SAID OUTPUT MEANS OF SAID ELECTRONIC OSCILLATOR MEANS; A BUFFER AMPLIFIER MEANS HAVING INPUT AND OUTPUT MEANS, SAID INPUT MEANS THEREOF BEING COUPLED TO SAID OUTPUT TERMINAL MEANS OF SAID ELECTRICAL ATTENUATION MEANS FOR RECEIVING A SIGNAL FROM SAID OSCILLATOR MEANS THERETHROUGH; A SERIES CRYSTAL PHASE SHIFTING MEANS COMPRISING A FIRST PHASE SHIFTING MEANS FOR SENSING ANY DEVIATIONS FROM A PREDETERMINED FREQUENCY IN SIGNALS PASSING THERETHROUGH AND INTRODUCING A PHASE SHIFT IN SAID SIGNALS PROPORTIONAL TO SAID DEVIATIONS IN FREQUENCY, SAID PHASE SHIFTING MEANS HAVING INPUT AND OUTPUT MEANS, IN INPUT MEANS THEREOF BEING COUPLED TO SAID OUTPUT MEANS OF SAID BUFFER AMPLIFIER MEANS; A FIRST TUNED AMPLIFIER AN LIMITER MEANS HAVING INPUT AND OUTPUT MEANS, SAID INPUT MEANS THEREOF BEING COUPLED TO SAID OUTPUT MEANS OF SAID FIRST PHASE SHIFTING MEANS; A SECOND PHASE SHIFTING MEANS FOR INTRODUCING A PHASE SHIFT OF PREDETERMINED AMOUNT INTO ANY SIGNAL PASSED THERETHROUGH, HAVING INPUT AND OUTPUT MEANS, SAID INPUT MEANS THEREOF BEING COUPLED TO SAID OUTPUT MEANS OF SAID OSCILLATOR MEANS; A SECOND TUNED AMPLIFIER AND LIMITER MEANS HAVING INPUT AND OUTPUT MEANS, SAID INPUT MEANS THEREOF BEING COUPLED TO SAID OUTPUT MEANS OF SAID SECOND PHASE SHIFTING MEANS; A PHASE DETECTOR MEANS HAVING A FIRST INPUT MEANS COUPLED TO SAID OUTPUT MEANS OF SAID FIRST TUNED AMPLIFIER AND LIMITER MEANS FOR RECEIVING A FIRST SIGNAL THEREFROM, HAVING A SECOND INPUT MEANS COUPLED TO SAID OUTPUT MEANS OF SAID SECOND TUNED AMPLIFIER AND LIMITER MEANS FOR RECEIVING A REFERENCE SIGNAL THEREFROM, AND HAVING AN OUTPUT MEANS COUPLED TO SAID INPUT MEANS OF SAID OSCILLATOR MEANS FOR PROVIDING THERETO A DIRECT CURRENT POTENTIAL PROPORTIONAL TO THE AMOUNT OF DEVIATION FROM A PREDETERMINED RELATIVE PHASE DIFFERENCE BETWEEN SAID FIRST SIGNAL AND SAID REFERENCE SIGNAL, TO REGULATE SAID VERNIER FREQUENCY CONTROL ELEMENT WITH SAID OSCILLATOR MEANS THEREBY CAUSING SAID OSCILLATOR MEANS TO MAINTAIN A VERY STABLE FREQUENCY OUTPUT SIGNAL; AND AN OUTPUT TERMINAL MEANS COUPLED TO SAID OUTPUT MEANS OF SAID OSCILLATOR MEANS, TO PROVIDE SAID VERY STABLE FREQUENCY OUTPUT SIGNAL THEREAT FOR UTILIZATION IN SUBSEQUENT CIRCUITRY.
