Monostable multivibrator utilizing common-base transistor to provide isolation between timing network and switching transistor

Claim 1

A MULTIVIBRATOR COMPRISING, IN COMBINATION, FIRST AND SECOND SWITCHING TRANSISTORS, EACH HAVING A CONTROL ELECTRODE AND A TRANSCONDUCTIVE PATH, A SOURCE OF AN OPERATING POTENTIAL, FIRST AND SECOND RESISTORS FOR CONNECTING THE TRANSCONDUCTIVE PATH OF SAID FIRST AND SECOND SWITCHING TRANSISTORS RESPECTIVELY ACROSS SAID SOURCE, A CAPACITOR HAVING FIRST AND SECOND TERMINALS, CIRCUIT MEANS FOR CONNECTING THE FIRST TERMINAL OF SAID CAPACITOR TO THE JUNCTION OF SAID FIRST RESISTOR AND THE TRANSCONDUCTIVE PATH OF SAID FIRST TRANSISTOR, A SOURCE OF A FIRST REFERENCE POTENTIAL, A RESISTIVE CIRCUIT PATH FOR CONNECTING THE SECOND TERMINAL OF SAID CAPACITOR TO SAID SOURCE OF SAID FIRST REFERENCE POTENTIAL, A THIRD TRANSISTOR HAVING A CONTROL CURRENT PATH AND A TRANSCONDUCTIVE PATH, A SOURCE OF A SECOND REFERENCE POTENTIAL, SAID CONTROL CURRENT PATH OF SAID THIRD TRANSISTOR BEING CONNECTED BETWEEN SAID SECOND TERMINAL AND SAID SOURCE OF SAID SECOND REFERENCE POTENTIAL, AND MEANS RESPONSIVE TO CHANGES IN THE CONDUCTIVITY OF THE TRANSCONDUCTIVE PATH OF SAID THIRD TRANSISTOR FOR APPLYING AN ACTUATING POTENTIAL TO THE CONTROL ELECTRODE OF SAID SECOND SWITCHING TRANSISTOR.
