Abstract

1,005,208. Electric selective signalling. RANK-BUSH MURPHY Ltd. Nov. 30, 1962 [Nov. 30, 1961], No. 42835/61. Heading G4H. [Also in Division H1] Numeral display cathodes in an indicator tube 11 are selectively energized by a selector tube 1 (see Division H1) comprising an electrode 5 mounted on a moving coil meter movement and separated by an apertured shield member 7 from an array of fixed electrodes which are connected to the cathodes of the indicator tube.
