Abstract: 258,013. Standard Telephones & Cables, Ltd., (formerly Western Electric Co., Ltd.), Searle, A. M., and Backer, J. H. E. June 13, 1925. Automatic exchange systems. - A register-controller of the code-translating type is provided with a compensating resistance which is normally included in series in the outgoing impulse-circuit but which may be shortcircuited by a relay at any predetermined stage of the exchange-selecting operations when the increase in length of the impulsing-circuit renders its presence undesirable, the inclusion or removal of the resistance being controlled by the setting of the exchange register, and its removal being effected by the same relay for all settings of the exchange register requiring its removal. The Figure shows the six banks A1 - A6 of the B- and C- digit register, corresponding terminals of these banks being connected through a distributing frame B to the bank of a counting-switch C, the bank A6 and contact B6 however being reserved for the control of the compensating resistance. It is assumed that the translated routing-number in the particular case considered is 2345 and that the first two of these digits control local switches whilst the last two control switches at a distant office. For the first two digits, the comparatively short impulse-circuit includes the extra resistance but when the third digit is about to be sent out, a circuit is completed over wiper W3, contact B3, jumper to contact B6, jumper to contact of bank A6, and wiper W6 for relay CR which operates to short-circuit the resistance.
