POWER DRIVEN BAND CLAMP FOR PENDULOUS NORTH SEEKING GYROSCOPES

摘要

A pendulum of a north seeking gyroscope is supported by a suspension band and is connected to the band by a movable pivot arm. The pivot arm permits the support point to be moved relative to the pendulum during its period in order to shorten the natural period of the north seeking gyroscope. A solenoid actuates the pivot arm in response to control signals which may be existing pick-off signals. Alternatively, the control signals may be provided by an electrolytic level transducer having an output signal proportional to the tilt angle and a phase indicative of tilt direction can be mounted on the gyroscope.
