1,105,818. Automatic steering control. SOCIETE FRANCAISE D'EQUIPEMENTS POUR LA NAVIGATION AERIENNE. Oct. 27, 1965 [Dec. 16, 1964], No. 45583/65. Heading G3R. In a system for automatically controlling the heading of a vehicle, the difference between the actual heading and a desired course results in rotation of a shaft which operates the rotor of an electrical signal generator through a non-linear coupling which ensures that rotation of the rotor never exceeds 180‹ despite a greater angle of rotation of the shaft. As applied to an automatic pilot, Fig. 2 (not shown), a synchronous electrical receiver 2 of compass signals is positioned by a follow-up servomotor 5 and operates a compass card 1. A pointer 8 indicating a desired course is manually rotatable relative to the card by a knob 12 operating through a differential gear which is also driven by motor 5. A cam 20 fixed to pointer 8 operates a transducer 14 to produce electrical signals for automatic course correction. Cam 20, Fig. 3 (not shown) has a spring-connected auxiliary segment 24 so arranged that, for a 200‹ movement in either sense, the transducer moves through less than 180‹ to a maximum deflection in a corresponding sense during the first 30‹ of movement of the cam and maintains that deflection during the remaining 170‹ of movement.
