Claims

9. A CONTROL CIRCUIT FOR A CONVERTIBLE AUTOMOBILE HAVING AN IGNITION SWITCH, A TOP MOVABLE BETWEEN A RAISED CLOSED POSITION AND A RETRACTED OPEN POSITION BY A MOVING MEANS, A PLURALITY OF WINDOWS MOVABLE BETWEEN OPEN AND CLOSED POSITION BY INDIVIDUAL MOVING MEANS, EACH OF SAID MOVING MEANS COMPRISING AN ELECTRICALLY ENERGIZABLE PRIME MOVER, SAID CONTROL CIRCUIT INCLUDING:

AN INPUT CIRCUIT;

A SENSOR DEVICE SECURABLE TO THE AUTOMOBILE IN A POSITION EXPOSED TO THE ATMOSPHERE WHOSE RESISTANCE DECREASES ON THE OCCURRENCE OF PRECIPITATION;

A SENSOR RELAY HAVING A WINDING;

AN IGNITION SWITCH TRANSISTOR AND A SENSOR TRANSISTOR HAVING EMITTER COLLECTOR CIRCUITS CONNECTED IN SERIES WITH SAID SENOR RELAY WINDING, SAID IGNITION TRANSISTOR HAVING ITS BASE EMITTER CIRCUIT CONNECTED IN SERIES WITH SAID IGNITION SWITCH AND SAID SENSOR TRANSISTOR HAVING ITS BASE EMITTER CIRCUIT CONNECTED IN SERIES WITH SAID SENSOR DEVICE;

A TOP SWITCH WHICH IS IN A FIRST OPERATIVE POSITION WHEN THE TOP IS IN ITS RETRACTED POSITION AND A SECOND OPERATIVE POSITION WHEN THE TOP IS IN ITS CLOSED POSITION;

A TOP RELAY FOR CONNECTING THE TOP PRIME MOVER ACROSS SAID INPUT CIRCUIT HAVING A WINDING CONNECTED ACROSS SAID INPUT CIRCUIT BY SAID SENSOR RELAY AND SAID TOP SWITCH WHEN SAID TOP SWITCH IS IN SAID FIRST OPERATIVE POSITION;

A THERMAL TIMER SWITCH, SAID SENSOR RELAY WINDING AND SAID EMITTER COLLECTOR CIRCUITS BEING CONNECTED ACROSS SAID INPUT CIRCUIT BY SAID TIMER SWITCH WHEN SAID TIMER SWITCH IS IN CLOSED POSITION, THE BASE EMITTER CIRCUIT OF SAID IGNITION TRANSISTOR BEING CONNECTED TO SAID INPUT CIRCUIT WHEN SAID TIMER SWITCH AND THE IGNITION SWITCH OF THE AUTOMOBILE ARE IN CLOSED POSITION TO PREVENT CONDUCTION IN THE EMITTER COLLECTOR CIRCUITS OF THE TRANSISTORS, THE BASE EMITTER CIRCUIT OF THE SENSOR TRANSISTOR BEING CONNECTED ACROSS SAID INPUT CIRCUIT BY SAID SENSOR DEVICE AND SAID TIMER SWITCH WHEN SAID TIMER SWITCH IS CLOSED;

AND A WINDOW RELAY HAVING A WINDING CONNECTED ACROSS SAID INPUT CIRCUIT BY SAID SENSOR RELAY AND SAID TIMER SWITCH WHEN SAID TOP SWITCH IS IN SAID SECOND OPERATIVE POSITION AND SAID TIMER SWITCH IS CLOSED, SAID WINDOW RELAY WHEN ITS WINDING IS ENERGIZED SIMULTANEOUSLY CONNECTING THE WINDOW PRIME MOVERS ACROSS SAID INPUT CIRCUIT, SAID TIMER SWITCH OPENING AFTER THE WINDOWS HAVE BEEN MOVED TO THEIR CLOSED POSITIONS.
