Abstract: 790,847. Digital electric calculating -apparatus. ELDI-FEINMECHANIK GES. July 9, 1954, No. 20109/54. Class 106 (1). In an electric totalizer for digits expressed as code combinations, comprising first and second input means, a signal combiner having a control system for each element of the code including input switching means, and a summing device, if identical code elements are put in simultaneously by both input means, the combiner sets twice the value of the code element in the summing device, whilst non- identical code elements put in simultaneously operate independently in the summing device. Figs. 2 and 3 show respectively a combiner and summing network for the addition of two decimal digits represented by code components 1, 2, 3, 5 entered by selectively closing contacts s1, s2, s3, s5 and t1, t2, t3, t5 of S- and T-relays (Figs. 1 and 1a, not shown). Corresponding contacts are connected via oppositely wound coils of relays E1, E2, E3, E5 to " double " relays G1, G2, G3, G5. If a pair of contacts such as s2, t2 are closed, the corresponding E-relay (E2) does not operate but a circuit is completed through the windings of this relay, a contact c and relay C; the latter relay opens contacts c whereby the corresponding G-relay (G2) is operated, the short circuit thereacross being removed. If, however, only one of a pair of contacts is closed, the E-relay operates and closes its contact, e.g. e2, thereby providing a further short circuit across the G-relay. The operated E- and G-relays actuate contacts in the summing network of Fig. 3, whereby the sum digit is obtained on output lines 11, 21, 31, 51 any carry appearing on line D1. The carry output operates a relay (not shown) which switches over contacts in a network for the S-relays whereby " 1 " is added to one of the next higher input digits. This network includes further contacts for obtaining the nines complement of the input digit for subtraction. The input digits are represented by closing electric contacts under control of e.g., storing relays, punched cards or a keyboard of a calculating machine.
