Filed: 1927-08-09
Abstract: 302,217. Associated Telephone & Telegraph Co., and Wicks, J. Aug. 9, 1927. Divided on 302,200. Drawings to Specification. Automatic exchange systems. - The invention relates to register-controllers for use in systems comprising revertive-control switches and consists in a register-controller in which each digit is registered on a separate relay counting set. Each set is in turn saturated by impulses from the corresponding R.-C. switch, the total number of impulses required from the dialled digit and the switch being variable in accordance with the value of the said digit and/or a previous digit. The number of relays in each counting set is less in number than the maximum number of impulses to be registered, and a pair of relays discriminate between odd and even digits for the purpose of controlling the saturation point. Further :relays are provided to control the distribution of the dialled digits, and a set of relays operates in the event of premature release or delayed dialling to control the restoration of the switch train by successively opening and closing the fundamental circuit. The invention is described in relation to an arrangement described in part of Specification 302,200, whereby calls from step-by-step to revertive-control exchanges are set up.
