Abstract

457,540. Light-current relays. STANDARD TELEPHONES & CABLES, Ltd., and TERRY, R. ST. G., 63, Aldwych, London. May 31, 1935, No. 15932. [Class 38 (v)] To prevent the armature of a light relay from sticking it is prevented from coming into contact with the polepieces by non-magnetic material. Either may be covered with hard rubber or synthetic resin, or fitted with hard rubber studs. To adjust the air gap metallic or non-metallic screws, or screws tipped with non-metallic material, may impinge on the plugs.
