Abstract

661,898. Automatic exchange systems. WESTERN ELECTRIC CO.. Inc. Jan. 28, 1949 [Jan. 30, 1948], No. 2408/49. Class 40 (iv). The two-winding relays of the individual digit registers disclosed in Fig. 4 of Specification 651,521 are replaced by single winding relays 12-16 controlling a contact lattice 29 which completes an operating circuit for an indicating relay N when any two out of five of the relays pull up, false operation of relay N over the holding contacts of the register relays being prevented by a rectifier 28 or a unidirectional thermionic device.
