Abstract

1,243,760. Impulse transmitters. GENERAL ELECTRIC CO. Ltd. 30 Sept., 1968 [29 Sept., 1967], No. 50833/70. Divided out of 1,236,569. Heading H4K. The description is almost identical to that of Specification 1,236,569, but the claims relate to the provision of an arcuate portion (annular projection 35), on the impulse wheel 13, which projection has a ramp 37 which separates contact 4] on contact spring 29 from contact 40 on spring 39 in the normal position of the impulse wheel.
