INCLINED GYROSCOPIC HORIZON 

(1950 US, by Frederick D Braddon & Wrigley Walter)

"This invention relates to gyroscopic artificial horizons, sometimes known as gyro-verticals, which are employed not only as visual indicators but also as base lines from which to control the lateral and longitudinal stability of aircraft and of sighting and radar equipment on ships, aircraft or other dirigible craft. Such gyroscopes are usually mounted in substantially neutral equilibrium, or made slightly pen-dulous, and are maintained in their normal positon primarily by gravitationally controlled erecting devices, such as pendulums or liquid level devices which govern a source of power applying a torque substantially normal to the direction of tilt..."

RATE OF TURN INTEGRATOR
(1951 US, by Paul A Noxon)

"The present invention relates to indicating instruments, and more particularly to means for accurately indicating, at all times, the magnetic heading of a mobile vehicle such as an aircraft, for example.

Devices heretofore provided for indicating a crafts magnetic heading during or after a turn of the craft have been either the magnetic compass or'the rate oi turn integrating device or the directional gyro. Magnetic compasses, as is well known, are subject to oscillations, particularly when used o n an aircraft and especially during a craft turnk and, hence, are practically useless for indicating the continuous change in magnetic heading during turn. Rate of turn integrating devices, on the other hand, are sufbject to certain inherent integration errors so that the final indication is either less or more than the actual angle of turn traversed by the craft, while directional gyros are subject to precession or creeping oi the set course, thereby necessitating frequent re-setting of the gyro...."
