1355307 Glass-metal seals PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 June 1972 [29 June 1971] 29843/72 Heading C1M [Also in Division H1] Conductor arrays 4 and 5 of a gas discharge display panel are secured to a first plate 1 and/or a light-pervious second plate 2 by glass enamel 6 which has a lower melting point than the material of the corresponding plate. Both plates 1 and 2 may be of window glass. The enamel 6 may cover the edges of the conductors 4 and 5 to prevent discharges occurring between adjacent conductors of the same array. A suspension of the enamel applied either to the conductors or to the plates 1 or 2 is melted when securing the conductor in position. The conductor arrays are preferably formed by photo-chemically etching slots in a metal plate or sheet, e.g. of Fe-Cr-Ni alloy to leave the conductors with their ends connected together by two sides of a rectangular frame formed by the remaining parts of the plate. The two sides of the frame parallel to the conductors are first removed and the conductors placed under tension, e.g. by springs attached to the other two sides of the frame, these sides being removed when the conductors have been secured to the plates. In a modified construction (Figs. 6 and 7, not shown) the conductors 5 are wires of Fe-Cr of circular cross-section which are each completely covered with a resistive layer, e.g. of semi-conductive glass, which may also be used to secure the wires to the plate 2.
