Abstract

621,817. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., BRAY, F. H., HARTLEY, G. C., and RIDLER, D. S. Oct. 30, 1946, No. 32238. Drawings to Specification. [Class 40 (iv)] A counting device comprises two sets of electric discharge tubes interconnected in pairs, one for each set, with further interconnections between pairs, triggering circuits by means of which a number may be set up directly on one set of tubes in binary notation and the complement on the other set of tubes, and means for counting out of the said device a number of impulses bearing a predetermined relationship to the number set up. The description is identical with that in Specification 621,816, but the claims differ.
