Abstract

868,760. Digital electric calculating-apparatus. BELL PUNCH CO. Ltd. Sept. 2, 1957 [Sept. 6, 1956; Nov. 22, 1956; July 3, 1957], Nos. 27575/57, 27576/57 and 27577/57. Divided out of 868,753. Drawings to Specification. Class 106 (1). The description is equivalent to that of Specification 868,759, but the claims are directed to complementing and shifting a number introduced by the actuation of a switch from the counting tube associated with the switch to the next higher counting tube. Specifications 868,756, 868,757, 868,758 and 868,761 also are referred to.
