Abstract
1,042,374. Cathode-ray tubes. COMPAGNIE FRANCAISE DE TELEVISION. April 17, 1963 [April 18, 1962], No. 12799/65. Divided out of 1,042,373. Heading H1D. A grid, for use adjacent the screen of a cathode-ray tube, comprises two parallel rods 12, Fig. 4, fixed to opposite sides of a frame, and a continuous wire 15 extending back and forth between the rods to form a plane wire surface. Each rod 12 has a longitudinal face formed with parallel transverse grooves separated by thread elements having overhanging end portions 29, the wire 15 being wound so as to lie in the grooves and pass alternately under one or more overhanging portions of one rod and then of the other. The grid may be used for focusing and post-deflection acceleration in a three gun colour display tube having a phosphor strip screen, the grid wires being aligned with the phosphor strips. The rods 12 may be screwed to the frame 10 and preferably have arcuate grooves, Fig. 3 (not shown). The phosphor screen may be supported from the grid frame, and this assembly may be mounted in the tube by four spring leaves.
