Abstract
411,872. Supply meters. FERRANTI, Ltd., and CHESWORTH, E., Hollinwood, Lancashire. Dec. 14, 1932, No. 35502. [Class 37.] In order to indicate visually the energization of an alternat. ing-current meter circuit, a continuously vibrating reed d is actuated by the field due to a coil a in series with the shunt or series meter windings. A resistance may be connected in series with the coil a, or the coil may be coupled through a transformer or auto-transformer tapping on the meter winding. Where more than one reed is employed, for example in polyphase meters, the reeds may be coloured differently.
