Abstract

470,008. Time switches. BROWN, R. F. Feb. 6, 1936, No. 3598. Drawings to Specification. [Class 38 (v)] [Also in Group XXXVIII] A controller for electric signalling or impulse transmitting mechanism comprises a rotatable member or members carrying projections arranged to co-operate with a series of contacts connected in a signalling circuit and a selecting device actuated automatically to connect a desired contact in the circuit. The controller is identical with that described in Specification 449,529.
