Variable "one-shot" multivibrator

Claim 1

IN A VARIABLE WIDTH PULSE GENERATOR THE COMBINATION COMPRISING, (A) A MONOSTABLE MULTIVIBRATOR HAVING TWO CROSS-CONNECTED CONDUCTIVE DEVICES HAVING A STABLE STATE DURING WHICH ONE OF THE DEVICES IS NORMALLY CONDUCTING AND THE OTHER OF WHICH IS NORMALLY NONCONDUCTING; (B) A TRIGGER INPUT TERMINAL COUPLED TO THE NORMALLY CONDUCTING DEVICE FOR REVERSING THE CONDUCTIVE STATES OF THE DEVICES IN RESPONSE TO A TRIGGER PULSE; (C) AN OUTPUT PULSE TERMINAL CONNECTED TO THE NORMALLY NONCONDUCTING DEVICE, THE WIDTH OF THE OUTPUT PULSE APPEARING AT SAID TERMINAL BEING EQUAL TO THE INTERVAL THAT THE NORMALLY NONCONDUCTING DEVICE IS IN THE CONDUCTING STATE; (D) A TIMING CIRCUIT COUPLED TO SAID MULTIVIBRATOR INCLUDING A VOLTAGE SENSITIVE SWITCH FOR GENERATING A PULSE WHICH RETURNS THE MULTIVIBRATOR TO ITS STABLE STATE, AN R-C BIASING NETWORK FOR SAID SWITCH WHICH CHARGES DURING THE INTERVAL THAT THE NORMALLY CONDUCTIVE STATES OF THE DEVICES HAVE BEEN REVERSED UNTIL A PREDETERMINED VOLTAGE LEVEL IS ACHIEVED AND SAID SWITCH CONDUCTS, THEREBY GENERATING A PULSE; (E) A CONTROL CIRCUIT COUPLED BETWEEN THE NORMALLY CONDUCTIVE DEVICE AND SAID TIMING CIRCUIT FOR PRODUCING A VOLTAGE PROPORTIONAL TO THE DURATION THAT SAID NORMALLY CONDUCTIVE DEVICE IS CONDUCTING, SAID CONTROL VOLTAGE VARYING THE TIME REQUIRED FOR THE R-C BIASING NETWORK TO CHARGE TO THE PREDETERMINED VOLTAGE LEVEL, THEREBY VARYING THE TIME THAT THE NORMALLY CONDUCTIVE DEVICE CONDUCTS AND THE WIDHT OF THE PULSE AT THE OUTPUT TERMINAL.
