Abstract

840,382. Producing electric pulses. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Feb. 21, 1958 [Nov. 22, 1956], No. 35740/56. Class 40 (3). [Also in Group XXXV] A toothed shutter disc 37 rotatable between a lamp and a photocell to produce pulses is mounted in a sealed housing 20 and coupled to an input shaft 17 by a magnetic coupling 30, 31. The cell output may operate a counter to indicate the movement of the shaft 17. Specification 815,336 is referred to.
