Vehicular alternator system with a voltage regulated battery charging circuit

Claim 1

A VEHICULAR ELECTRICAL SYSTEM FOR AN AUTOMOBILE INCLUDING IN COMBINATION, AN ALTERNATOR HAVING A PLURALITY OF ARMATURE WINDINGS AND A FIELD WINDING, AN OUTPUT CONDUCTOR, A PLURALITY OF RECTIFIERS CONNECTING SAID ARMATURE WINDINGS TO SAID OUTPUT CONDUCTOR TO PROVIDE DIRECT CURRENT AT SAID OUTPUT CONDUCTOR WITH RESPECT TO A REFERENCE POINT FOR THE SYSTEM, SAID ALTERNATOR HAVING A MAGNETIC STRUCTURE OF SUCH MAGNETIC RETENTIVITY TO REQUIRE SEPARATE EXCITATION OF SAID FIELD WINDING UPON INITIAL OPERATION THEREOF, AN ISOLATION DIODE, A STORAGE BATTERY SERIES CONNECTED WITH SAID ISOLATION DIODE BETWEEN SAID OUTPUT CONDUCTOR AND THE REFERENCE POINT, SAID DIODE BEING POLED TO BE NON-CONDUCTIVE WHEN THE VOLTAGE BETWEEN SAID OUTPUT CONDUCTOR AND THE REFERENCE POINT IS LESS THAN THE VOLTAGE OF SAID BATTERY, A VOLTAGE REGULATOR HAVING INPUT CONNECTIONS CONNECTED BETWEEN SAID OUTPUT CONDUCTOR AND THE REFERENCE POINT, SAID VOLTAGE REGULATOR FURTHER HAVING A FIELD TERMINAL AND A CONDUCTIVE PATH BETWEEN SAID OUTPUT CONDUCTOR AND SAID FIELD TERMINAL, MEANS CONNECTING SAID FIELD WINDING BETWEEN SAID FIELD TERMINAL AND THE REFERENCE POINT, SWITCH MEANS AND AN INDICATOR LAMP CONNECTED IN SERIES ACROSS SAID ISOLATION DIODE WITH SAID SWITCH MEANS BEING CONNECTED BETWEEN SAID BATTERY AND SAID INDICATOR LAMP, AND AN IGNITION SYSTEM FOR THE VEHICLE CONNECTED BETWEEN SAID SWITCH MEANS AND THE REFERENCE POINT TO BE ENERGIZED BY SAID BATTERY THROUGH SAID SWITCH MEANS, WHEREBY ENERGIZING CURRENT FOR SAID FIELD WINDING OF SAID ALTERNATOR IS PROVIDED FROM SAID BATTERY THROUGH SAID INDICATOR LAMP AND SAID CURRENT PATH OF SAID REGULATOR WITH SAID SWITCH MEANS CLOSED, AND SAID ALTERNATOR WHEN OPERSAID SWITCH MEANS CLOSED, AND SAID ALTERNATOR WHEN OPERATING PROVIDING CURRENT THROUGH SAID RECTIFIERS TO SAID OUTPUT CONDUCTOR AND THROUGH SAID CONDUCTIVE PATH OF SAID REGULATOR TO SAID FIELD WINDING MEANS FOR ENERGIZING THE SAME.
