Claims

1. IN A MULTIVIBRATOR CIRCUIT HAVING FIRST AND SECOND ELECTRONIC CONTROL ELEMENTS, EACH HAVING FIRST AND SECOND MAIN ELECTRODES AND A CONTROL ELECTRODE AND WHEREIN SAID FIRST MAIN ELECTRODES OF SAID CONTROL ELEMENTS ARE INTERCONNECTED FOR CONNECTION TO A FIRST SOURCE OF VOLTAGE POTENTIAL, AND WHEREIN THE SECOND MAIN ELECTRODE OF SAID FIRST CONTROL ELEMENT IS CONNECTED TO THE CONTROL ELECTRODE OF SAID SECOND CONTROL ELEMENT BY MEANS OF A CAPACITOR, THE IMPROVEMENT COMPRISING:

INDUCTIVE MEANS CONNECTED IN SERIES TO SAID SECOND MAIN ELECTRODE OF SAID FIRST CONTROL ELEMENT AND FOR CONNECTION TO A SECOND SOURCE OF VOLTAGE POTENTIAL, SO THAT THE LOAD CURRENT OF SAID FIRST CONTROL ELEMENT WHEN CONDUCTIVE IS PASSED THROUGH SAID INDUCTIVE MEANS;

A DISCHARGE RESISTOR CONNECTED TO SAID CAPACITOR AT THE SIDE THEREOF CONNECTED TO SAID CONTROL ELECTRODE;

AND A DIODE CONNECTED ACROSS SAID DISCHARGE RESISTOR AT SUCH A POLARITY OPPOSITE TO THE DIRECTION OF THE DISCHARGE CURRENT THROUGH SAID DISCHARGE RESISTOR AS EXISTENT DURING THE TIME OF CURRENT CONDUCTION THROUGH SAID FIRST CONTROL ELEMENT.
