Abstract

756,419. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. Jan. 9, 1953 [Feb. 13, 1952], No. 12067/55. Divided out of 756,322. Drawings to Specification. Class 40 (4). In a cold cathode gas-discharge tube switch for connecting a line to one of a group of lines, each line of the group is allotted a time position in a recurring cycle and pulses applied in the same time position to both sides of the switch effect the connection of the corresponding line. The description is identical with part of that of Specification 756,322 which claims other features.
