Abstract

868,761. Digital electric calculating-apparatus. BELL PUNCH CO. Ltd. Sept. 2, 1957 [Sept. 6, 1956; Nov. 22, 1956; July 3, 1957], Nos. 27581/57, 27582/57 and 27583/57. Divided out of 868,753. Drawings to Specification. Class 106 (1). The description is equivalent to a part of that of Specification 868,753, but the claims relate to the interdenominational transfer for which there is provided a single carry store common to all the counting tubes. Specifications 868,756, 868,757, 868,758, 868,759 and 868,760 also are referred to.
