Free rotor gyroscope

Claim 1

IN A GYROSCOPE, A ROTOR AT LEAST A PORTION OF WHICH IS FABRICATED OF A NONMAGNETIC MATERIAL, AND AT LEAST A PORTION OF WHICH HAS HIGH ELECTRICAL CONDUCTIVITY, A CASE SURROUNDING SAID ROTOR, AT LEAST A PORTION OF SAID CASE COMPRISING A SPHERICAL MEMBER TO WHICH SAID ROTOR IS EXTERNALLY CONCENTRIC, SAID ROTOR HAVING A SPHERICAL SURFACE ADJACENT TO SAID SPHERICAL CASE MEMBER SAID SPHERICAL SURFACE OF SAID ROTOR HAVING TAPERED WEDGE-SHAPED PADS ETCHED THEREON, WHEREBY A SPHERICAL GAS BEARING TO SUPPORT SAID ROTOR IS FORMED BETWEEN SAID ROTOR SPHERICAL SURFACE AND SAID SPHERICAL MEMBER OF SAID CASE, MOTOR FIELD WINDINGS WOUND ON A MAGNETIC CORE FIXEDLY MOUNTED ON SAID CASE IN PROXIMITY TO SAID ELECTRICALLY CONDUCTIVE ROTOR PORTION, ALTERNATING CURRENT MEANS FOR EXCITING SAID FIELD WINDINGS TO DRIVE SAID ROTOR ABOUT A PREDETERMINED ROTATION AXIS, AN INSULATING RING, TWO PAIRS OF OPPOSITELY ORIENTED ELECTRICALLY CONDUCTIVE PICKOFF PLATES MOUNTED THEREIN, SAID ROTOR HAVING FLAT SURFACES NORMAL TO SAID ROTATION AXIS, SAID INSULATING RING BEING BONDED TO SAID CASE AND POSITIONED ADJACENT AND PARALLEL TO ONE OF SAID FLAT SURFACES, ELECTRICAL MEANS CONNECTED TO EACH OF SAID PAIRS OF PICKOFF PLATES FOR GENERATING A DIRECT CURRENT WHOSE POLARITY INDICATES WHICH OF SAID PLATES IS CLOSER TO SAID ROTOR THAN ITS PAIRED OPPOSITE AND WHOSE MAGNITUDE INDICATES THE DIFFERENCE OF THE CAPACITANCE BETWEEN EACH OF SAID PLATES AND SAID ROTOR AND THAT OF ITS PAIRED OPPOSITE, A BALL BEARING RACE FIXEDLY MOUNTED ON SAID SPHERICAL CASE MEMBER, A SHAFT SET IN THE ROTATABLE PORTION OF SAID BALL BEARING RACE, A STOP PIN MOUNTED ON SAID SHAFT, SAID ROTOR HAVING A CIRCULAR RECESS, SAID STOP PIN ORIENTED WITH ITS ROTATION AXIS PARALLEL TO SAID ROTOR ROTATION AXIS AND POSITIONED IN SAID RECESS FOR LIMITING MOTION OF SAID ROTOR NORMAL TO SAID ROTOR ROTATION AXIS, TWO PAIRS OF TORQUING WINDINGS EACH WINDING OF A PAIR BEING LOCATED AROUND OF SAID ROTATION AXIS, AND SAID PAIRS BEING LOCATED AROUND SAID AXIS AT RIGHT ANGLES TO EACH OTHER, SAID WINDINGS ADJACENT SAID ROTOR FOR CAUSING ROTOR TORQUE, AND A CONSTANT DIRECT CURRENT SOURCE FEEDING EACH OF SAID WINDINGS.
