Transistor sawtooth generator circuit

Claim 1

A SAWTOOTH GENERATOR CIRCUIT COMPRISING: A VOLTAGE SOURCE; FIRST AND SECOND TRANSISTORS HAVING EMITTER, BASE, AND COLLECTOR ELECTRODES; FIRST CIRCUIT MEANS FOR CONNECTING SAID BASE ELECTRODE OF SAID FIRST TRANSISTOR TO SAID VOLTAGE SOURCE SO AS TO PROVIDE A CONSTANT BIASING VOLTAGE TO SAID FIRST TRANSISTOR; SECOND CIRCUIT MEANS HAVING A PREDETERMINED RESISTANCE FOR CONNECTING AND EMITTER ELECTRODE OF SAID FIRST TRANSISTOR TO GROUND; A CAPACITOR COUPLED BETWEEN SAID COLLECTOR ELECTRODE OF SAID FIRST TRANSISTOR AND GROUND; THIRD CIRCUIT MEANS FOR CONNECTING SAID CAPACITOR TO THE EMITTER-COLLECTOR CIRCUIT OF SAID SECOND TRANSISTOR; FOURTH CIRCUIT MEANS FOR CONNECTING SAID EMITTER-COLLECTOR CIRCUIT OF SAID SECOND TRANSISTOR TO SAID VOLTAGE SOURCE; A SCHMITT TRIGGER FOR TURNING ON SAID SECOND TRANSISTOR WHEN SAID CAPACITOR IS DISCHARGED TO A PREDETERMINED LEVEL BY SAID FIRST TRANSISTOR, THEREBY CHARGING SAID CAPACITOR TO THE POTENTIAL OF SAID VOLTAGE SOURCE, SAID SCHMITT TRIGGER BEING CONNECTED TO SAID BASE OF SAID SECOND TRANSISTOR, AND FIFTH CIRCUIT MEANS FOR CONNECTING SAID CAPACITOR TO SAID SCHMITT TRIGGER.
