Abstract
758,770. Colour television tubes. CHROMATIC TELEVISION LABORATORIES, Inc. June 11, 1954 [June 29, 1953], No. 17178/54. Class 39 (1). Inflexible zig-zag rods 30, 32, 34 of insulating material, prevent vibration of the colourswitching grid 14 adjacent the screen of a television colour tube. Adjacent rods 30, 32, 34 interleave with the grid wires 14 in opposite directions. A suitable ratio between the voltages on the screen and grid is given for ensuring that the rods cast no shadow on the screen.
