Claim 1
Independent Claim
210 words
A BASE; A SUPPORT MOUNTED BY A GIMBAL MEANS ON SAID BASE FOR RELATIVE ROTATION THEREWITH ABOUT A PAIR OF MUTUALLY PERPENDICULAR AXES; A SUBSTANTIALLY SPHERICALLY SHAPED ROTOR UNIVERSALLY SUPPORTED BY SAID SUPPORT AND ADAPTED TO BE ROTATED ABOUT A SPIN AXIS; MEANS MEASURING RELATIVE ROTATION BETWEEN SAID ROTOR (WHEN SPINNING ABOUT SAID SPIN AXIS) AND SAID SUPPORT ABOUT A PAIR OF AXES MUTUALLY PERPENDICULAR TO ONE ANOTHER AND TO SAID SPIN AXIS, SAID ROTATION MEASURING MEANS INCLUDING A PLURALITY OF RADIATION SENSORS MOUNTED ON SAID SUPPORT AND ADAPTED TO SENSE RADIATION FROM SAID ROTOR, SAID ROTOR AND SAID SENSOR BEING ORIENTABLE AND BEING NORMALLY ORIENTED SO THAT SAID SENSORS STRADDLE A SPIN AXIS PORTION OF THE SURFACE OF SAID ROTOR, AND SAID SENSOR PRODUCING SIGNALS INDICATIVE OF RELATIVE DISPLACEMENT (TRANSVERSE TO THE SPIN AXIS) OF THE SENSING MEANS AWAY FROM THE SPIN AXIS BY BEING RESPONSIVE TO VELOCITY OF RELATIVE MOVEMENT BETWEEN THE SENSORS AND THE PORTION OF ROTOR SURFACE VIEWED THEREBY; MOTOR MEANS CONNECTED TO SAID GIMBAL MEANS; AND MEANS FOR APPLYING THE SIGNALS PRODUCED BY SAID SENSOR TO SAID MOTOR MEANS SO THAT SAID SUPPORT AND SAID SENSOR THEREON ARE SERVOED TO REMAIN IN SUBSTANTIAL REGISTER WITH SAID SPIN AXIS PORTION OF SAID SURFACE OF SAID ROTOR.
