Abstract

395,120. Electric discharge tube signs. ROBERTS, C. A. N., (trading as LUND BROS. & CO.), 57, Blackfriars Road, London. April 21, 1932, No. 11442. [Class 3 (ii).] In an electric discharge tube sign a plurality of bright surface rods are arranged to form a grating in front of the discharge tube shaped as the sign and a reflecting surface is disposed behind the tube so that light from the tube falling on the grating is reflected back and dispersed by the reflecting surface. As shown, the discharge tube 3, supported by brackets 2 on a correspondingly shaped reflecting backing 4, is provided with a grating comprising rods 5. Rods 5a on either side may also b e provided. The backing 4 may be of corrugated or zig-zag cross-section.
