    Abstract: A bidirectional gas discharge tube (GDT) (100) includes a discharge chamber (110), first and second cathodes (104,106), a gas (116) disposed within the discharge chamber, and a control grid (108). The first and second cathodes are disposed within the discharge chamber and include first and second faces, respectively. The first face and the second face are plane-parallel. The gas is configured to insulate the first cathode from the second cathode. The control grid is disposed between the first and second cathodes within the discharge chamber. The control grid is configured to generate an electric field to establish a conductive plasma between the first and second cathodes to close a conduction path extending between the first and second cathodes.

    Abstract: A cold-cathode switching device is presented. The cold-cathode switching device (100) includes a housing (110) defining a chamber (111); an ionizable gas (112) disposed in the chamber; and a plurality of electrodes (120) disposed in the chamber. The plurality of electrodes includes a cathode (124) and an anode (122) defining a discharge gap, and wherein at least one of the cathode and anode comprises a material (140) that is liquid at an operating temperature of the cathode or the anode.

    Abstract: 1,190,394. Discharge lamps. PERKINELMER CORP. 12 June, 1967 [24 June, 1966], No. 27064/67. Heading H1D. In a hollow cathode lamp for atomic absorption spectroscopy, a metal for investigation forms a thin coating 30 on the interior surface of a hollow cathode 10 which has inturned ends 22 to prevent the coating material, melted during the operation of the lamp, running out of the cathode. The cup material is chosen to ensure that no alloy is formed with the coating metal having a melting point lower than that of the coating metal, e.g. titanium is used for a coating of tin or indium, or niobium for a coating of gallium. The cup is provided with a cylindrical aperture 16 for the receipt of a lamp stem assembly. A tin coating in the cup is formed by introducing tin shot into the cup, flushing, baking out, and sealing the lamp after the introduction of a few torr of neon, and running the lamp at a sufficiently high current to melt the tin, whereafter the lamp is tilted and rolled about its axis to cause the tin to wet and coat the interior of the cup. A gallium or indium coating may be formed by introducing the molten material into the cup, or by heating the cup, and centrifuging prior to assembly of the lamp.

    Abstract: 784,440. Metal-vapour converters. SIEMENSSCHUCKERTWERKE AKT.-GES. May 13, 1955 [May 14, 1954], No. 13957/55. Class 39(1). In a mercury arc rectifier having a cathode container of metal, the bottom of which is closed in part by a glass seal, the container having an internal coating of enamel which is covered by an additional layer of insulation having a higher melting point than said enamel coating and consisting of enamel, glass, glassenamel or glass-like substances, the additional layer covers the coating of enamel in the neighbourhood of the glass seal to prevent damage to the enamel when the seal is being made. In the construction shown, a metal container 1 for mercury 12 has a coating of a number of layers of enamel 2 and an additional layer 3 of glass or enamel. A tube 7, forming a passage for a conductor (not shown) which leads to the mercury pool and which closes the tube 7 to prevent the escape of mercury therethrough, has a coating 8 of enamel and is sealed to the container 1 by a glass seal 5 resting on a graphite support 6 and surrounded by a pressure ring 11. In a further embodiment, a metal base carrying two cathode terminal lugs is sealed by means of a glass ring to a cylindrical metal container provided with an enamel coating and an additional insulating layer as specified above.
