Patent GB-831336-A (GB)
Abstract: 831,336. Gyroscopic apparatus. KELVIN & HUGHES Ltd. Oct. 8, 1957 [Oct. 15, 1956], No. 31366/56. Class 97(3) [Also in Group XXXVII] The inner gimbal of a gyroscopic instrument has mounted thereon a mercury switch 19, Fig. 2, which consists of an envelope 20 containing a mercury globule 24 and two switching means 21, 22 and 21, 23 closed respectively by the mercury when the inner gimbal is rocked in one direction or the other, the floor 25 of the envelope being convex upwards. The floor 25 may be ground or etched to roughen it. As shown in Fig. 1, the gyroscope rotor 10 of a directional gyroscope is mounted in gimbals 12, 14, the outer gimbal 14 being rotatable about an axis 15 by a motor 16. The switch 19 is mounted on the inner gimbal 12. The switch is so connected between a current source 26 and the motor 16 that, when the gimbal 12 tilts from its horizontal position, the mercury 24 bridges the electrodes 21, 22 or 21, 23 to energize motor 16 to impart a torque which precesses the gyroscope back to the horizontal position. On continued precession the mercury moves from one end of the envelope 20 to the other, and the motor torque is reversed. As a result of the convex form of the floor 25, the switch constantly reverses its position, and this minimizes the effect of the weight of the mercury when moved away from the centre of the switch, and also reduces the effect of friction in the gimbal bearings. Neon lights 27, 28 are connected in the switch circuit to be lit alternately as the switch changes position, so as to indicate that the instrument is operating correctly.
