Abstract

791,856. Automatic exchange systems. BRITISH TELECOMMUNICATIONS RESEARCH, Ltd. Nov. 8, 1955 [Nov. 19, 1954], No. 29315/57. Divided out of 791,855. Drawings to Specification. Class 40 (4). A magnetic drum stores impulses in a position which is the same for all the various trains of impulses on a line and subsequently transfers the impulses to a storage position characteristic of the train of impulses concerned. The description and drawings are also contained in Specification 791,855, but the claims differ. Specifications 717,688, 717,689 and 717,690 also are referred to.
