Abstract

819,494. Etectric indicating systems. KELVIN & HUGHES Ltd. July 26, 1957 [Aug. 8, 1956], No. 24330/56. Addition to 788,544. Class 40 (1). Apparatus for measuring the rotation of a compass magnet 11 relative to a craft on which it is mounted comprises a semi-conductor crystal 10 mounted coaxially with the magnet and in its magnetic field, fed with A.C. along its horizontal axis 12, 13 so that any angular displacement of this axis relative to the horizontal axis of the magnet produces a P.D. across the vertical axis 17, 18 by the Hall effect, which is fed to a motor 22 to realign the axes of the crystal 10 and the magnet 11. The rotation may be telemetered via a known transmitter 26 to remote receivers.
