Abstract

1,096,193. Cathode-ray tubes. RANK ORGANISATION Ltd. Jan. 26, 1965 [Jan. 27, 1964], No. 3398/64. Heading H1D. A cathode-ray tube has a plurality of elemental beams arranged in a row, the row of beams being jointly deflected generally transversely of the row, wherein each beam may be selectively switched on or off at predetermined points of the deflection so as to produce an alphanumeric display on a screen. Alternatively the tube may be used as a radar display tube, an additional beam being used to display target echoes on the screen. A plurality of cathodes may be used to form the elemental beams, each being selectively switched on or off, or a plurality of beam modulating electrodes arranged in a row are provided, one cathode being used to flood the row.
