Abstract

353,836. Electrically-operated valves. MILLS, T. A., Laurieston, Saltburn-by-Sea, and BOSANQUET, W. S. B., Gainford, Darlington. April 30, 1930, No. 17253/31. Divided on 353,948. [Class 135.] In apparatus for regulating gas pressure, a rod 2 which moves up and down in accordance with the variation of the pressure, carries a contact disc 8 which is adapted to come into bridging engagement with one or other of two pairs of gravity-controlled nearly-balanced contact arms 10, 11, thereby closing circuits to relays which operate an electric motor in one direction or other, the motor operating a valve controlling the supply of gas.
