Regulator arrangement for lowvoltage generators

Claim 1

A REGULATOR ARRANGEMENT FOR A LOW-VOLTAGE GENERATOR OPERABLE AT VARYING SPEEDS AND HAVING A FIRST AND A SECOND OUTPUT LINE CARRYING OPPOSITE POLARITIES, COMPRISING, IN COMBINATION, AN EXCITER COIL HAVING TWO ENDS AND BEING CONNECTED AT ONE END WITH SAID FIRST OUTPUT LINE; TRANSISTOR MEANS HAVING A BASE ELECTRODE, AND HAVING AN EMITTER ELECTRODE CONNECTED WITH SAID SECOND OUTPUT LINE, AND A COLLECTOR ELECTRODE CONNECTED WITH THE OT HER END OF SAID EXCITER COIL; ELECTROMAGNETIC RELAY MEANS INCLUDING A RELAY WINDING AND A NORMALLY OPEN RELAY SWITCH OPERABLE BY ENERGIZATION OF SAID RELAY WINDING AND ARRANGED IN PARALLEL WITH THE EMITTER-BASE CIRCUIT OF SIAD TRANSISTOR MEANS; FIRST RESISTOR MEANS CONNECTED BETWEEN SAID BASE ELECTRODE OF SAID TRANSISTOR MEANS AND ONE END OF SAID RELAY WINDING; SECOND RESISTOR MEANS CONNECTED BETWEEN SAID ONE END OF SAID RELAY WINDING AND THE OTHER END OF SAID EXCITER COIL, THE OTHER END OF SAID RELAY WINDING BEING CONNECTED WITH THAT ONE OF SAID OUTPUT LINES WHICH IS NOT CONNECTED WITH SAID OTHER END OF SAID EXCITER COIL WITH WHICH SAID SECOND RESISTOR IS CONNECTED, WHEREBY SAID TRANSISTOR IS NORMALLY CONDUCTIVE SO AS TO PASS EXCITER CURRENT THROUGH ITS EMITTER-COLLECTOR CIRCUIT, BUT IS RENERED NON-CONDUCTIVE SO AS TO INTERRUPT EXCITATION WHEN THROUGH INCREASE OF GENERATOR OUTPUT VOLTAGE SAID RELAY MEANS ARE ENERGIZED TO SHUNT THE EMITTER-BASE CIRCUIT OF SAID TRANSISTOR.
