Abstract

1435213 Pulse generators SINGER CO 16 Oct 1973 [29 May 1973] 48101/73 Heading G1N A reference pulse generator comprises a semicircular cam 12 Fig. 1 rotated by a shaft 14 near a Hall plate device 20 attached via a permanent magnet 32 to a bracket 34. The magnetic flux from the rear pole face of the magnet 32 passes through the bracket 34, a disc 44, shaft 14 and cam 12 to the Hall plate device 20 and the front pole face of the magnet. Hence the Hall plate device provides a voltage at one level when the cut-away portion of the cam face the device 20 and at a higher level when the full part of the cam faces the device 20. The Hall plate element in device 20 may alternatively be a magnetoresistive element.
