Abstract
456,383. Electromagnetic switches. INTERNATIONAL BUSINESS MACHINES CORPORATION, 270, Broadway, New York, U.S.A.-(Assignees of Bugge, V. M.) July 22, 1935, No. 20791. Convention date, July 26, 1934. [Class 38 (v)] [See also Groups XL and XXXVIII] In a relay for use ir a telegraph receiving system in which a circuit corresponding to a signalled character has to be selected, wher the solenoid plunge] 55 is attracted, four contacts 47a ... 47d arranged in two pairs side by side, are closed at once and a further contact 47a is closed a little later by the tail 56.
