Abstract

788,593. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. Aug. 27, 1954 [Sept. 2, 1953], No. 4473/55. Divided out of 788,592. Drawings to Specification. Class 40 (4). The description is identical with that of Specification 788,592 but the claims relate to an automatic exchange in which every complete operation of a selector switch to make a connection takes place within one of a succession of identical time periods, in which a single connection only can be in the process of establishment through a given switching stage during the same one of these identical time periods, and in which connection operations may be in progress at different switching stages of the exchange in respect of different connections during the same one of these time periods. Specifications 692,415, 734,345, [both in Group XL (a)], 756,322, 788,591, 788,594 and 788,595 also are referred to.
