Gyroscope

Claim 1

A GYROSCOPE COMPRISING A CLOSED CASING DEFINING A CYLINDRICAL CHAMBER, A CYLINDRICAL GIMBAL OF NON-MAGNETIC MATERIAL DISPOSED WITHIN THE CHAMBER AND HAVING A HUB PORTION ON EACH END, SAID GIMBAL BEING MOUNTED FOR ROTATION ABOUT AN OUTPUT AXIS EXTENDING LONGITUDINALLY THEREOF BY A PAIR OF MAGNETIC SUSPENSION DEVICES, EACH SUSPENSION DEVICE INCLUDING A DISK-SHAPED MAGNET WITH A CENTRAL POLE OF ONE POLARITY AND A COAXIAL ANNULAR POLE OF THE OTHER POLARITY, EACH SUSPENSION DEVICE ALSO INCLUDING A DISK-SHAPED ARMATURE WITH A CENTRAL POLE AND A COAXIAL ANNULAR POLE ADAPTED FOR ALIGNMENT WITH CORRESPONDING POLES OF SAID MAGNET, THE MAGNETS BEING MOUNTED ON OPPOSITE ENDS OF THE CASING IN COAXIAL RELATION WITH SAID CYLINDRICAL CHAMBER, THE ARMATURES BEING MOUNTED OF RESPECTIVE HUB PORTIONS IN ENGAGEMENT THEREWITH AND COAXIALLY OF THE GIMBAL IN AXIALLY SPACED RELATION WITH THE RESPECTIVE MAGNETS WHEREBY THE GIMBAL IS RESTRAINED AGAINST RADIAL DISPLACEMENT BY THE MAGNETIC FIELD OF SAID MAGNETS, THRUST MEANS COACTING BETWEEN THE GIMBAL AND CASING FOR LIMITING THE AXIAL DISPLACEMENT OF THE GIMBAL, A VISCOUS LIQUID FILLING THE SPACE BETWEEN THE GIMBAL AND THE CASING AND SUPPORTING THE GIMBAL IN SUBSTANTIALLY NEUTRAL BUOYANCY, GYROSCOPIC MEANS DISPOSED WITHIN SAID GIMBAL AND DEFINING A GYROSCOPE INPUT AXIS EXTENDING TRANSVERSELY OF SAID OUTPUT AXIS, AND A SIGNAL GENERATOR INCLUDING A MAGNETIC FIELD PRODUCING MEMBER ON SAID CASING AND A MAGNETIC FIELD RESPONSIVE MEMBER ON SAID GIMBAL ADAPTED TO DEVELOP AN OUTPUT SIGNAL CORRESPONDING TO DISPLACEMENT OF THE GIMBAL ABOUT SAID OUT AXIS.
