Abstract

853,329. Correspondence control devices. ULTRA ELECTRONICS Ltd., [formerly ULTRA ELECTRIC Ltd.]. April 17, 1959 [May 21, 1958], No. 16337/58. Class 40 (1). In a transducer utilizing either the Hall effect or the magnetoresistive effect, a semiconductor lamina is embedded between two high-permeability semicylindrical members 1, and spaced from the circumference and ends thereof, and the cylindrical rotor thus formed is mounted between the poles 2 of a magnetic circuit so as to be rotatable about its own axis. The Hall voltage output, or the semi-conductor resistance, depends upon the magnitude of the component of magnetic flux normal to the lamina, i.e. upon the angular position of the rotor. Preferred semi-conductor material for the lamina is an alloy of elements of Group III and Group V of the Periodic Table, e.g. indium arsenide or indium antimonide. When Hall effect is utilized, the transducer output, which passes through zero and is bidirectional, may be connected in opposition to an external signal source, e.g. a thermocouple, to produce a differential control signal. When the magnetoresistive effect is used, the semi-conductor lamina may be connected in a bridge circuit comprising a similar lamina; this arrangement gives a null output at zero setting with temperature compensation. The cylindrical rotor produces a sinusoidal output; if an output with an extended linear portion is required, the shape of the rotor may be modified, or a suitable mechanical link or cam arrangement may be used.
