Claim 1
Independent Claim
194 words
A PULSE CONTROL CIRCUIT INCLUDING THE COMBINATION OF: AN OSCILLATOR CIRCUIT HAVING OUTPUT RESISTANCE MEANS FOR DEVELOPING A SERIES OF FIRST PULSES OF A GIVEN DURATION, A PULSE UTILIZATION DEVICE HAVING INPUT RESISTANCE MEANS ADAPTED TO BE SWITCHED BETWEEN DIFFERENT CONDUCTIVE STATES, INDUCTANCE MEANS COUPLING SAID OSCILLATOR CIRCUIT TO SAID PULSE UTILIZATION DEVICE COOPERATING WITH SAID INPUT AND OUTPUT RESISTANCE MEANS TO DEVELOP SECOND PULSES OF A LONGER DURATION, A PREDETERMINED AMPLITUDE OF SAID SECOND PULSES DRIVING SAID PULSE UTILIZATION DEVIE INTO ONE OF SAID CONDUCTIVE STATES, SAID INDUCTANCE MEANS, SAID OUTPUT RESISTANCE MEANS AND SAID INPUT RESISTANCE MEANS FORMING A TIME CONSTANT NETWORK, THE VALUE OF SAID INDUCTANCE MEANS BEING SELECTED SO THAT IN COMBINATION WITH SAID OUTPUT RESISTANCE MEANS AND SAID INPUT RESISTANCE MEANS THE RISE TIME OF EACH OF SAID CONTROL PULSES IS NOT APPRECIABLY DIFFERENT THAN THE RISE TIME OF EACH OF SAID FIRST PULSES, AT LEAST UNTIL SAID SECOND PULSE REACHES SAID PREDETERMINED AMPLITUDE, THE VALUE OF SAID INDUCTANCE MEANS BEING FURTHER SELECTED SO THAT EACH OF SAID SECOND PULSES REMAINS ABOVE SAID PREDETERMINED AMPLITUDE FOR A TIME INTERVAL GREATER THAN THE DURATION OF EACH OF SAID FIRST PULSES.
