Abstract: A display device including an electron tube for image reproduction comprising an electron source having a substantially flat emissive surface and comprising a display screen discrete points of which are caused to luminesce by electrons impacting upon a luminescent substance. The selection of the points to be caused to luminesce is performed with the aid of two grids arranged between the electron source and the display screen, each of which have non-intersecting electrodes, a so-called cross-bar. The surface of at least one grid facing the electron source is provided with an insulating or poorly conductive plate having closely adjacent, substantially parallel, narrow passages. The passages have conductive surfaces. The surface of the plate in which the passages are opening out and on which no grid is provided is covered with an electrically conductive layer. The passages are, in particular, secondary-emissive.

Abstract: A method of adjusting two metallic electrodes surfaces in an electric discharge tube at a given distance from each other in which an intermediate layer of non-metallic material, e.g. carbon or a metal oxide, is provided between the surfaces of the electrodes which are placed in abutting relationship. The electrodes are then heated to a temperature of about 780*C to connect them with supporting members and cooled. Due to different coefficients of expansion of the electrodes and supporting members, the electrodes separate and the intermediate layer is then removed.

Abstract: A television camera tube having an elongate envelope comprising two cylindrical parts. The cylindrical part which is connected to the face plate has a larger diameter than the other cylindrical part and comprises a gauze electrode secured to a supporting ring. This supporting ring is clamped between the face plate and the neck between the two cylindrical parts by means of resilient pressure means. A circular rounding of the neck on the side of the cylindrical part with the smallest diameter is to be preferred, said rounding being covered with a conductive layer. A few dimensions are given related to the diameter of the cylindrical part of the smallest diameter. The ratio between the voltages at the gauze electrode and the conductive layer preferably is between 1.65 and 2.35.
