Abstract: A lamp for use in subterranean galleries such as mines in which the cold-cathode discharge tube is received in a housing which, in turn, is removably mounted in a receptacle and is held in place by a ring clamping a flange of the housing against a flange of the receptacle. The housing may be provided with a translucent cover so that the housing can be removed and replaced as a unit. A reed switch on the receptacle cooperates with a magnet on the housing to deenergize the terminals of the housing upon its removal. The terminals of the discharge tube are embedded in an insulating potting mass within the housing.

Abstract: A tube socket is especially adapted for use with a longitudinally extending cathode ray tube of the type having a plurality of high voltage pins and a plurality of relatively low voltage pins spaced apart, with each of the high voltage pins being encased in a protective silo. The socket includes a cap member defining a silo filler open at the bottom thereof and adapted to enter the tube silo. High voltage terminals mounted on the cap member extend into the silo fillers and are adapted to conductively receive the high voltage pins.

Abstract: A multiple filament lamp has one set of ends of all filaments connected to a common conductor and the end of another set individually connected to separate conductors. The conductors are mounted in a non-conducting lamp base with the common conductor projecting centrally beyond the bottom of the base, and the separate conductors recessed into the side of the base and equally spaced around its circumference. The base is slidable into a socket-adapter having an outer conducting shell defining standard electric socket screw threads fixed to an inner non-conducting cylinder that is recessed interiorly at the top to receive a retainer ring for engaging a similar recess around the top of the lamp base, and recessed exteriorly to receive a conductor contact spring for biasing a spring end extending through the non-conducting cylinder inwardly into separate engagement with the respective conductors recessed in the lamp base as the lamp and its base are turned in the socket-adapter.

Abstract: One of a pair of electrodes forming a spark gap is connected to a flexible coupling link and the other is extended to form an electrode terminal pin. A molding piece for fixing the spark gap is mounted by molding on at least one pair of electrodes. A common terminal is formed as a unitary structure with the coupling link. The coupling link is bent to conform to a cathode ray tube socket and incorporated therein.

Abstract: External cylindrical current conductors of an electric lamp are torpedo-shaped at the end which is welded to a metal foil in a pinch seal of the lamp vessel.The torpedo-shaped part has a length which is at least equal to the diameter of the cylindrical part, while the diameter of the torpedo-shaped part at a distance from the cylindrical part of 0.9 times the cylinder diameter is at most equal to half the cylinder diameter.Also when comparatively thick external current conductors, approximately 1.5mm diameter, are used and at a high temperature of the pinch seal, the lamps will withstand cracking. The welded joint of the conductors to the metal foil is stronger than in known lamps.

Abstract: An improved lamp and socket assembly is disclosed in which a socket collar is mechanically secured to the panel or reflector when the lamp is used. The base of the lamp attaches to the collar as does the electrical connector. The combination enables a more repeatable alignment of the lamp in the panel or reflector. A compact assembly is achieved by using nested cylinders in the parts.

Abstract: A connector set is provided for use in apparatus for the production of a direct-current electrostatic field, comprising a first electrode situated, e.g., near a room ceiling, connected to the high direct-current voltage power supply of a television receiver, and a counterelectrode at ground potential, e.g.

Abstract: A spark plug connector for use in ignition systems of internal combustion engines, said connector having a spark gap component in which two double offset or stepped configuration electrodes are disposed facing each other in a gas-tight discharge tube, said electrodes being electrically insulated and spaced from each other to define a discharge gap therebetween.

Abstract: The invention provides a quick disconnect device for use between image insifier tubes and their power supply or their supporting apparatus.

Abstract: A one-piece sheet metal base for a tubular lamp having pinch-sealed ends is adapted to be simply pushed onto the lamp end by hand. It comprises a flat portion having longitudinally extending side wall portions exceeding slightly in height the thickness of the pinch seal with inwardly turned underbeveled extensions which resiliently grip the pinch seal for frictional retention. A distal end wall portion has a forwardly turned lip adapted to overlie a pigtail attached to the inlead. Mitered corners on the underbeveled extensions and on the end wall provide a passage for threading the pigtail through the base.
