Variable delay time pulse generator

Claim 1

A MULTIVIBRATOR CIRCUIT FOR PRODUCING A PULSE OF VARIABLE DURATION, SAID MULTIVIBRATOR CIRCUIT COMPRISING: FIRST AND SECOND GAIN ELEMENTS, EACH HAVING AN INPUT AND AN OUTPUT: FIRST CIRCUIT MEANS INTERCONNECTING SAID FIRST AND SECOND GAIN ELEMENTS, SAID FIRST CIRCUIT MEANS INCLUDING AN ENERGY STORAGE DEVICE CONNECTED BETWEEN THE OUTPUT OF SAID FIRST GAIN ELEMENT AND THE INPUT OF SAID SECOND GAIN ELEMENT FOR PROVIDING THE MULTIVIBRATOR CIRCUIT WITH AT LEAST ONE UNSTABLE ELECTRICAL CONDITION IN WHICH SAID FIRST GAIN ELEMEMT IS NONCONDUCTIVE OF CURRENT AND SAID SECOND GAIN ELEMENT IS CONDUCTIVE OF CURRENT FOR AN INTERVAL OF TIME DURING WHICH THE OUTPUT PULES IS PRODUCED; A UNIDIRECTIONAL CONDUCTING ELEMENT HAVING A PAIR OF TERMINALS, ONE OF WHICH IS CONNECTED TO SAID FIRST CIRCUIT MEANS AT A POINT INTERMEDIATE TO SAID ENERGY STORAGE DEVICE AND THE OUTPUT OF SAID FIRST GAIN ELEMENT FOR BEING SUPPLIED WITH AN ELECTRICAL POTENTIAL; SWITCHING MEANS HAVING A PLURALITY OF STATES AND BEING CONNECTED TO THE OTHER TERMINAL OF SAID UNIDIRECTIONAL CONDUCTING ELEMENT FOR SUPPLYING A DIFFERENT ELECTRICAL POTENTIAL FOR EACH OF SAID STATES TO SAID OTHER TERMINAL TO REVERSE BIAS SAID UNIDIRECTIONAL CONDUCTING ELEMENT AND THE BEGINNING OF SAID UNSTABLE ELECTRICAL CONDITION; AND SECOND CIRCUIT MEANS CONNECTED TO SAID ENERGY STORAGE DEVICE FOR ALTERING DURING SAID UNSTABLE ELECTRICAL CONDITION THE AMOUNT OF ENERGY STORED IN SAID ENERGY STORAGE DEVICE TO ALTER THE ELECTRICAL POTENTIAL SUPPLIED TO SAID ONE TERMINAL SO AS TO FORWARD BIAS SAID UNIDIRECTIONAL CONDUCTING ELEMENT, WHEREBY SAID UNSTABLE ELECTRICAL CONDITION IS TERMINATED AT A DIFFERENT TIME FOR EACH STATE OF SAID SWITCHING MEANS.
