Title: A transmission system for the transmission of numerical and functional values from a calculating machine to a remote data processing machine
IPC: G06F3/09
Filed: 1958-05-02
Abstract: 871,043. Calculating-machines. OLYMPIA WERKE A.G. May 2, 1958 [Sept. 24, 1957], No. 14068/58. Addition to 867,718. Class 106 (1). In a system for transmitting numbers and function symbols from a calculating-machine to a remote data-processing machine, the arrangement is such that the effect of a second symbol signal depends on the nature of a first symbol signal. The first and second symbol signals are derived from the calculating machine described in the parent Specification in which a contact carriage moves over projections 14a, Fig. 1, of slides differentially positioned in accordance with the digits of a number and of a forked slide 214 differentially positioned according to the sign of the number and the function performed, and having its two arms spaced on either side of the digit slides. The arrangement enables the machine to function correctly in response to signals derived from a punched tape suitable also for use in a teleprinter. When an amount is received which is to be added or subtracted in the machine, the digit signals are preceded by a space signal and followed by a plus or minus signal. The space signal energizes a relay R L  which then holds, and its contacts r L2  prepare add and subtract relays, M add, M sub. The plus or minus signal then energizes a corresponding relay R + or R - and its contacts r +  2  or r -  2  energize the relay M add or M sub. which initiates an add or subtract operation. However, a total may be transmitted to the machine for checking against the machine's own total. In this case, a total or subtotal signal precedes the digit signals and energizes a corresponding relay R*, R<>, the contacts r* 2  or r <> 2  of which energize a relay M* or M<> over the contacts r L2  in their rest position. The machine is thus caused to carry out a total or subtotal operation. The digit signals are followed by a plus or minus signal according to the sign of the transmitted total. This causes the relay R + or R - to be energized. The contacts r +  3  or r -  3  then energize a non-add relay M# which causes the received amount to be printed, adjacent to the total or subtotal of the machine itself, to enable the two amounts to be visually compared. If the received digit signals are followed by a minus signal (indicating a negative total), the relay R - will be energized and also, over contacts r -  4 , a relay M red, which causes the received amount to be printed in red.
