    Abstract: In a color picture tube of the single-gun, plural-beam type in which all of the beams pass through the center of an electron lens for focusing the beams on the color phosphor screen with two of the beams emerging from the lens along paths divergent from the optical axis of the lens, and pairs of convergence deflecting plates are arranged along the divergent paths and have voltages applied thereacross to produce electric fields by which the divergent beams are deflected for converging all of the beams at a common point on the aperture grill associated with the screen; the outer plate of each pair of convergence deflecting plates is mounted with respect to the corresponding inner plate by means of conductive members extending outwardly from the latter past the sides of the outer plate to glass or insulating members extending across the outer surface of the outer plate, and hence disposed outside the electric field, and the ends of the outer plate are preferably bent outwardly to shield the electric field from the effect of the potential of the adjacent insulating members.

    Abstract: In a color picture tube having an electron gun within the neck portion of its envelope for directing and focusing a plurality of electron beams at a color phosphor screen on a face plate of the conical envelope portion, a first high voltage for operation of the gun is supplied to the latter through a conductive layer on the inner surface of the conical envelope portion, and a second high voltage required for operation of the gun is supplied to the latter by way of a lead wire extending within the conical envelope portion through a conductive tubular member which is electrically connected with the conductive layer and insulated from the lead wire. The conductive tubular member is electrically connected with the conductive layer by an arcuate spring member which further serves to accurately and securely position the tubular member and the lead wire therein within the tube envelope, thereby ensuring proper engagement with the gun of a contact member that extends from the lead wire.

    Abstract: In a cathode ray tube of the type in which a plurality of electron beams are directed toward a phosphor screen by a beam generating assembly and are made to intersect each other substantially at the optical center of a main focusing electron lens by which all of the beams are focused on the screen, the usual grid electrode assembly is provided with an additional or auxiliary electrode for at least one of the beams, which auxiliary electrode has applied thereto a selected voltage by which the beam cutoff voltages for the plural beams can be maintained at selected values while permitting independent control of the modulation conditions for the several beams.

    Abstract: In a color picture tube of the single-gun, plural-beam type in which a central beam and two side beams originate in a common plane and are all made to pass through the center of an electron lens for focusing the beams on the color screen with the central beam emerging from the lens along the optical axis of the latter and the side beams emerging from the lens along paths that are oppositely divergent from the axis, the divergent side beams are acted upon by an electrostatic convergence deflecting device constituted by pairs of spaced plates arranged along the divergent paths and having voltages applied thereacross to produce electric fields by which the divergent side beams passing therethrough are deflected to converge at a common spot with the central beam on the apertured grill or mask associated fields the screen, and a main deflection yoke produces magnetic fields in the direction of the common plane of the beams and orthogonally thereto for causing the beams to scan the screen; the distances between the plates of each pair are varied in the direction perpendicular to the common plane in which the beams originate to correspondingly vary the strengths of the electric fields and thus correct distortions in the rasters of the side beams.

    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: In a single-gun, plural-beam color picture tube in which two beams emerge from a focusing lens along paths that diverge from a central beam emerging along the optical axis of the lens by which all of the beams are focused on the color screen, and the divergent beams are deflected to converge with the central beam by passage through respective electrical fields established between first spaced plates, at opposite sides of the central beam path, and second plates spaced outwardly from the first plates; such plates are disposed closely adjacent to the main deflection yoke by which the beams are made to scan the screen so that the length of the tube can be minimized, and the misconvergence of the beams that may result from the magnetic field produced between the first plates by reason of a current flow induced in the first plates by flux change of the magnetic field of the main deflection yoke is corrected by providing the second plates with different dimensional relationships to the first plates, for example, different distances from the first plates or different distances along the first plates, so that the deflecting effects of the electrical fields are correspondingly different.
