Abstract
723,784. Electromagnetic relays. STANDARD TELEPHONES & CABLES, Ltd. April 24, 1952 [Sept. 24, 1951], No. 22274/51. Class 38 (5). The core of a relay is formed from two U- shaped members, parts 1 and 2 of which are in close contact and carry the winding and parts 5 and 6 of which define a gap adapted to be bridged by an armature lying substantially parallel to the core. The plate-like members 1, 2 may be replaced by rod and tube members, Figs. 6, 7 (not shown). Specification 723,806 is referred to. The Provisional Specification refers to Specification 566,778.
