    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 and an auxiliary electrode having open areas therein disposed along the outer side of the respective divergent path spaced inwardly from the plate which is at the side of the respective divergent path away from which the beam is deflected, this plate being at a relatively low potential and the auxiliary electrode and the other plate being at substantially the same relatively high potential to establish an electric field between the plates which, in the region thereof located between the other plate and the auxiliary electrode and being traversed by the respective beam, has a potential gradient that is maintained substantially constant irrespective of variations in the relatively high potential to avoid misconvergence due to such variations.

    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.

    Abstract: A shielding mechanism for isolating the positively charged neck of a color cathode ray tube from a plurality of cathodes within such neck, in which a steel plate covers the open end of a grid which housed the aforementioned cathodes. The grid also has formed therein separators to eliminate the effects of intercathode electric field reaction which may result from dissimilar potentials of the cathodes.

    Abstract: An indicator display tube in which indicator electrode units, each consisting of anode and cathode segments, lie in the same plane and in which all of the cathode segments are simultaneously energized and the anode segments are energized on a time sequential basis in such a manner that only the indicator electrode unit having its anode segments energized will glow at a particular time. The cathode segments of each indicator unit are connected in parallel. The indicator display tube has barrier segments for preventing accidental discharge of adjacent indicator electrode units which would produce erroneous message displays. At least the cathode but preferably all of the segments are formed of a silver paste coated with nickel. The base material on which the silver paste is coated is glass. This arrangement prevents sputtering.
