Abstract
362,082. Changing signs. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and RYDE, J. W., of General Electric Co., Wembley, Middlesex. Oct. 9, 1930, No. 30263. [Classes 3 (i) and 3 (ii).] A display sign comprises an electric discharge lamp, of the type in which a flickering effect is produced by the wandering of the luminous column in the tubular lamp due to the introduction of impurities into the gas, placed behind a diffusing screen such as a sheet of ground glass. The lamp may be backed by a white diffusing surface, and a colour filter, which may be in the form of a film on the lamp, may be located between the lamp and the screen. Specification 349,261 is referred to.
