Electronic circuit crystal controlled transistor oscillator multiplier circuit

Claim 1

A SINGLE TRANSISTOR OSCILLATOR-MULTIPLIER CIRCUIT INCLUDING IN COMBINATION, A TRANSISTOR HAVING BASE, EMITTER AND COLLECTOR ELECTRODES, FREQUENCY DETERMINING MEANS HAVING A RESONANT FREQUENCY COUPLED BETWEEN SAID BASE ELECTRODE AND A REFERENCE POTENTIAL, SAID FREQUENCY DETERMINING MEANS HAVING A PORTION COUPLED TO SAID EMITTER ELECTRODE TO PROVIDE FEEDBACK THERETO, CAPACITOR MEANS COUPLED BETWEEN SAID BASE ELECTRODE AND SAID REFERENCE POTENTIAL, TUNED CIRCUIT MEANS COUPLED BETWEEN SAID COLLECTOR ELECTRODE AND SAID REFERENCE POTENTIAL AND HAVING A LOW IMPEDANCE AT SAID RESONANT FREQUENCY SO THAT SAID COLLECTOR ELECTRODE IS EFFECTIVELY CONNECTED DIRECTLY TO SAID REFERENCE POTENTIAL WITH RESPECT TO SAID RESONANT FREQUENCY, SAID TRANSISTOR, SAID FREQUENCY DETERMINING MEANS, AND SAID TUNED CIRCUIT MEANS FORMING AN OSCILLATOR CIRCUIT PROVIDING AN OUTPUT SIGNAL CONTAINING FREQUENCIES EQUAL TO SAID RESONANT FREQUENCY AND HARMONICS THEREOF, SAID TUNED CIRCUIT MEANS BEING RESONANT AT A PREDETERMINED HARMONIC FREQUENCY OF SAID RESONANT FREQUENCY WHEREBY A SIGNAL HAVING A FREQUENCY EQUAL TO SAID PREDETERMINED HARMONIC FREQUENCY IS DEVELOPED ACROSS SAID TUNED CIRCUIT MEANS, SAID CAPACITOR MEANS PROVIDING A LOW IMPEDANCE PATH TO SAID BASE ELECTRODE FOR SAID PREDETERMINED HARMONIC FREQUENCY SIGNAL.
