Abstract

1324458 Gyroscopes NORTH AMERICAN ROCKWELL CORP 22 Sept 1971 [5 Oct 1970] 44190/71 Heading G1C [Also in Division G3] A rotating gyroscope ball has its centre of mass laterally displaced from its spin axis to enable levitating forces to control the speed of rotation. In the embodiment shown, a gyroscope ball 11 comprises a sphere of beryllium with a thin layer of a dense metal 13 on one side to displace the centre of mass a distance d from the geometric centre which, in operation, orbits about the spin axis. Levitation is produced by eight electrodes, each formed as an octant of a sphere, and energized in opposed pairs. As the ball rotates, its spacing from the electrodes varies cyclically, and electrical signals are taken from the electrodes to control the levitation and spin axis attitude. The signals are also used to produce a servo component in the current energizing the electrodes and thus form an accelerating or decelerating couple on the ball, Fig. 10a, to maintain its speed in accordance with a reference set by a resonant circuit or by an external source of pulses (see Division G3).
