Abstract
398,797. Automatic circuit-breakers. LEYHAUSEN, W., 79, Bucherstrasse, Nuremberg, Germany. Dec. 18, 1931, No. 35113. Void [Abridged as open to inspection under Sect. 91 of the Acts, Jan. 23, 1932]. [Class 38 (v).] Magnetic blow-outs.-In a small overload cut-out in which a single pair of coils c, d operate the tripping armature e and provide a blow-out field for the contacts at k, one or both coils are mounted perpendicularly to the main magnetic limbs a, b, whereby a more concentrated blow-out field is obtained without seriously weakening the 'tripping field.
