| abstract | 900,431. Cathode-ray tubes. MULLARD Ltd. March 6, 1961, No. 38065/61. Class 39 (1). An elongated cathode-ray tube, having an electron gun at one end, comprises one or more elongated phosphor strips T lying in the longitudinal direction of the envelope near one side thereof so as to be visible through an opposite window portion W of the envelope, and a shield structure 7 having a plurality of longitudinal non-reflecting surfaces 7A facing the target to intercept light therefrom which would otherwise strike parts of the envelope other than the window W at glancing angles causing internal reflection. As shown, 3 colour phosphor strips T are supported by an aluminium carrier 8 in good thermal contact with the shield structure 7 which is of an aluminium alloy with a matt black enamel coating and which serves also to dissipate heat from the target. The shield structure is supported at its ends by discs engaging the envelope and is in electrical contact with a conductive coating on the gun end of the envelope. The window W may be provided with a transparent conductive coating of tin oxide, or may have. adjacent thereto a metal mesh, e.g. parallel tensioned wires 15, or 2 sets of interlaced wires or a stainless steel stocking mesh, electrically connected to the shield 7. After insertion of the shield into the envelope from the end opposite the gun, this end is closed by a glass disc sealed to the envelope with a low melting-point glaze. The tube may be used with magnetic scanning means as described in Specifications 865,666 and 890,395, or may be modified for electrostatic scanning as described in Specification 865,663, and may be used in a display system employing mechanical frame scanning means as described in Specifications 827,851, 846,544 and 865,665. |
