Regulating device for electric generators

Claim 1

REGULATOR ARRANGEMENT FOR A LOW-VOLTAGE GENERATOR OPERABLE AT VARYING SPEEDS AND HAVING AN OUTPUT CIRCUIT AND AN EXCITER CIRCUIT, SAID ARRANGEMENT COMPRISING, IN COMBINATION, TRANSISTOR MEANS HAVING AN EMITTER ELECTRODE AND A COLLECTOR ELECTRODE CONNECTED IN SERIES WITH THE EXCITER CIRCUIT OF THE GENERATOR, AND HAVING A BASE ELECTRODE CONNECTED WITH THE GENERATOR OUTPUT CIRCUIT SO AS TO NORMALLY RENDER SAID TRANSISTOR CONDUCTIVE; RELAY MEANS HAVING COIL MEANS AND A FIRST CONTROL RESISTOR CONNECTED IN SERIES THEREWITH, THE RESULTING SERIES COMBINATION BEING CONNECTED WITH THE GENERATOR OUTPUT CIRCUIT FOR BEING ENERGIZED BY A PREDETERMINED CURRENT DEPENDING UPON THE VARYING OUTPUT VOLTAGE OF THE GENERATOR AND CONTROLLED BY SAID FIRST CONTROL RESISTOR, AND NORMALLY OPEN CONTACT MEANS OPERABLE BY ENERGIZATION OF SAID COIL MEANS BY SAID PREDETERMINED CURRENT AND CONNECTED IN PARALLEL WITH THE EMITTER-BASE CIRCUIT OF SAID TRANSISTOR MEANS SO AS TO RENDER SAID TRANSISTOR MEANS NON-CONDUCTIVE WHEN SAID CONTACT MEANS ARE CHANGED TO CLOSED POSITION UPON ENERGIZATION OF SAID COIL MEANS DEPENDING UPON A PREDETERMINED VALUE OF SAID GENERATOR OUTPUT VOLTAGE, A SECOND CONTROL RESISTOR BEING CONNECTED BETWEEN SAID BASE ELECTRODE AND A JUNCTION POINT WITHIN SAID SERIESCOMBINATION FOR DETERMINING THE POTENTIAL OF SAID BASE ELECTRODE REQUIRED FOR RENDERING SAID TRANSISTOR MEANS CONDUCTIVE.
