Title: Improvements in or relating to control systems for navigated craft
IPC: G01C19/30
Filed: 1950-07-16
Abstract: 686,561. Automatic steering control systems. GLENNY, A. P., and SPERRY GYROSCOPE CO., Ltd. June 1, 1951 [July 16, 1950], No. 16076/50. Class 38 (iv). In setting an automatic pilot to maintain an axis of a craft in a new direction, a directional reference instrument (e.g. gyro) is temporarily declutched from a primary element of its pickoff which is thereupon centralized relative to a secondary element by means which exert no centralizing force while the primary element is clutched to the reference instrument. For controlling an aircraft in azimuth, a directional gyro 2 moves, through gearing 6, 7, and a shaft 9, a slider 14 of a potentiometer 15 fixed to the craft, to produce a signal dependent on course deviation of the aircraft. Shaft 9 is mounted at one end in a universal pivot bearing 10 and at the other end it is located in a slot 19, with the straight portion of a spring 23 urging it in the direction producing engagement of gears 6 and 7. To set the aircraft on a new course a knob 30 is temporarily rotated from a central position to bank the craft through means not shown to a degree dependent on the angle through which knob 30 is turned. Movement of knob 30 from its central position also closes cam-operated contacts 26, 27 to energize winding 24 of an electromagnet 17 which attracts an armature 12 to move shaft 9 in slot 19 against spring 23 until it engages an adjustable rolling stop 20. Gears 6 and 7 are thus disengaged and at the same time the shape of armature 12 is such that it rotates to centralize slider 14 so that the signal from the potentiometer is zero.
