Abstract

685,324. Eddy-current brakes. MEASUREMENT, Ltd. April 19, 1951 [June 19, 1950], No. 15243/50. Class 35. Meter-disc braking magnets 4 are of U- shape and their flux is localized by the use of soft iron counterpoles 6 to reduce magnetic coupling with the driving members 2. The magnets, which are fitted on mild-steel blocks 5, and the counter poles are mounted on non-magnetic frame 3. The braking action may be adjusted by turning the magnets or moving them radially of the disc, or using variable magnetic shunts. Specification 588,628, [Group XXXIV], is referred to.
