    Abstract: In a cathode ray tube in which a plurality of electron beams are focused on a screen by a focusing lens from which at least certain of the beams emerge along paths divergent with respect to the tube axis, and each of the beams emerging along a divergent path is deflected to cause convergence of the beams at a common area of the screen; such deflection of each diverging beam is effected by a pair of plates at different electrical potentials disposed at opposite sides of the respective divergent path to electrostatically deflect the beam therefrom, and the plate which is at the side of the respective divergent path away from which the beam is deflected is also divergent from the tube axis in the direction toward the screen so as to avoid impingement on such plate of electrons from the respective beam.

    Abstract: In a color picture tube having plural beams emitted from a cathode structure to pass through respective apertures of a control grid structure for intensity modulation and being focused to impinge on respective color phosphors, the relationship of beam currents required for good white balance is achieved by giving a relatively large area to the control grid aperture corresponding to the beam, particularly the green beam, which is to have a relatively high beam current. Preferably, the grid aperture of large area is divided into parts so as to achieve the necessary increased beam current without a corresponding change in the cutoff voltage.

    Abstract: A color picture tube or other cathode-ray tubes in which a plurality of electron beams emanating from one or more cathodes are made to converge substantially at the optical center of an electrostatic focusing lens which focuses the beams on an electron receiving screen. When beams are focused on the electron receiving screen are all to converge at a common point on such screen an electrostatic or magnetic deflection device acts on those beams which diverge after passing through the lenslike focusing system. A grid is positioned adjacent the electron receiving screen of the tube in order to sharply focus the electron beams on the electron receiving screen. The support for the grid structure is stressed to compensate for any expansion of the grid wires due to heating. The support has a pair of opposed parallel arms with the grid wires attached to and extending transversely between the arms and a pair of braces supporting the arms at the bessel point, the braces being stressed in a direction substantially parallel to the direction of the grid wires so that as the grid wires expand due to heat, the braces will expand a corresponding amount to maintain a substantially constant tension on the grid wires.
