IN A TRANSISTORIZED INVERTOR FOR INVERTING A D.C. POTENTIAL INTO A PULSATING SIGNAL HAVING AN AMPLITUDE CORRESPONDING TO THE MAGNITUDE OF THE D.-C POTENTIAL, COMPRISING IN COMBINATION, A SOURCE OF D.-C. POTENTIAL A TRIODE JUNCTION TRANSISTOR HAVING AN EMITTER, A COLLECTOR AND A BASE, A CIRCUIT CONNECTING THE D.-C. POTENTIAL SOURCE ACROSS THE EMITTER AND COLLECTOR, MEANS FOR OSCILLATING THE POTENTIAL OF SAID BASE WHEREBY SAID CIRCUIT IS ALTERNATELY OPENED AND CLOSED TO THEREBY PRODUCE THE PULSATING SIGNAL, AND MEANS FOR RENDERING THE AMPLITUDE OF THE SIGNAL INDEPENDENT OF THE AMBIENT TEMPERATURE OF THE TRANSISTOR INCLUDING AN IMPEDANCE CONNECTED IN SAID CIRCUIT AND A SECOND SOURCE OF D.-C. POTENTIAL CONNECTED ACROSS SAID IMPEDANCE.
