Abstract

868,758. Digital electric calculating-apparatus. BELL PUNCH CO. Ltd. Sept. 2, 1957 [Sept. 6, 1956; Nov. 22, 1956; July 3, 1957], Nos. 27569/57, 27570/57 and 27571/57. Divided out of 868,753. Drawings to Specification. Class 106 (1). The description is equivalent to that of Specification 868,757, but the claims relate to the transfer of a number from one counting tube to another counting tube by applying a predetermined number of pulses to the tubes, pulses being applied to the first tube until that tube registers a predetermined number, the remaining pulses being applied to the other tube. Specifications 868,756, 868,759, 868,760 and 868,761 also are referred to.
