Abstract

5510. Western Electric Co., [Woodward, F. T., acting for Western Electric Co.]. March 6, 1913. Drawings to Specification. Automatic exchange systems.-The setting of the automatic switches is controlled by rapid interruptions of the line circuit, the changeover from one switch to another being effected by a longer interruption of the same circuit, while the release of the switches is caused by the prolonged interruption produced by the subscriber hanging up his receiver. The system in connexion with which the invention is described is a register-controller system and is identical with that shown in Specification 5653/13. Specification 895/14 also is referred to.
