Abstract

448,692. Changing signs. MINNS, R. H., 21, Chapel Avenue, Addlestone, Surrey. Nov. 4, 1935, No. 29415/34. [Class 3 (i)] In stroboscopic signs and the like in which a disc perforated with clesigns &c. rotates in front of circular concentric electric discharge tubes, the perforations are in the form of two or more rings of openings, all of the same size and equally spaced apart. The number of openings therefore differs in each ring, and with certain lamp frequencies and speeds of the disc d moving effects in different directions are produced. The tubes f, g may be independent and be energized by currents of different frequencies, and current frequency differences may be obtained by the use of half-wave rectifiers. The tubes may be of different colours.
