Abstract

925,163. Electronic decimal dividing apparatus. BELL PUNCH CO. Ltd. June 15, 1959 [June 19, 1958], No. 8503/60. Divided out of 925,161. Drawings to Specification. Class 106 (1). The claims relate to a calculating machine in which division is effected by successive subtraction of the (decimal) divisor from the dividend until the latter is reduced below zero, when it is shifted and complemented before the next series of subtractions takes place. The subject-matter appears in Specification 925,161. Specification 853,136 also is referred to.
