Abstract: A device including a hub portion, said hub portion including an opening with spring-loaded electrical contacts slidably disposed in said opening, a light rail an extended portion and a power contact disposed on the extended portion, wherein the light rail is operable to slide into the opening and couple the power contact to the spring-loaded contact. The extended portion may include an o-ring for fixing the light rail and the hub may have a cable for mounting and coupling power to the spring-loaded electrical contact. Some embodiments may have a second opening in said hub portion, and a second end for the light rail. Power may be coupled through the light rail to hubs on each end.

Abstract: An electrical device including a device body having a rear section configured to fit into an electrical box and at least one device mounting tab having an aperture for a fastener, a front section secured directly to the rear section, and an interchangeable face removably secured to the front section. The interchangeable face may include a frame surrounding a movable element.

Abstract: Disclosed herein is a dental lamp socket assembly especially adapted for use with dental lamps. The dental lamp socket assembly is configured to dramatically increase the ease at which bulbs can be placed and/or replaced in and out of the socket assembly.

Abstract: Option cards—one or more as may be installed in a particular computer system—are retained in position against possibly dislodgement due to handling by a frame and cooperating cross bar and depending member elements which may be variously positioned relative to the frame.

Abstract: A plasma display device has a pair of substrates having electrodes and terminals provided at ends of the electrodes. Driving circuits supply a driving voltage to the electrodes via flexible printed circuit boards to emit light. Connectors are detachably attached to the substrate. The connector includes a housing and terminal members disposed in the housing, with the terminal member having a U-shaped cross-sectional shape, so that a first portion as one leg of the “U” contacts the terminal of the electrode and a second portion as another leg of the “U” contacts the conductor of the flexible connecting member. The terminals of the electrodes are arranged in a staggered manner at the end of the substrate.

Abstract: A light fixture for a double-ended lamp includes a first insulator containing a first electrical socket and a well in communication therewith and having a greater depth than the first socket. A second insulator has a second electrical socket and a slot in communication with the second socket and is biased by a spring into a first position. To install the lamp, a first end of the lamp is placed into the well and a second end of the lamp is then slid through the slot in the second insulator into contact with the second socket. The second insulator is then retracted into a second position to allow the first end of the lamp to slide from the well into the first socket. The second insulator is released to allow the bias of the spring to press upon the ends of the lamp to firmly secure each end into its respective socket.

Abstract: A discharge lamp unit in which a pair of terminal and lead support assemblies (A, B), composed of a pair of metal connector terminals (123, 125) and a pair of metal lead supports (122, 124), are fixedly held by a molded resin lamp holder (120) in such a manner that the connector terminals (123, 125) extend from the rear surface of the lamp holder while the lead supports (122, 124) extend from the front surface of the lamp holder to support a discharge lamp (110). The lamp holder has an axial through-hole formed therein during the molding of the lamp holder in a metal mold in such a manner that the axial through-hole is located between the connector terminals of the terminal and lead support assemblies, whereby the lamp holder is enhanced in dielectric strength.

Abstract: A one-piece, molded plastic spring clip, which is substantially inverted U-shape in cross-section, has a bight portion including an opening receiving a screw threaded fastener to attach the clip to the rear surface of a lamp holder so that the screw threaded fastener does not extend from the clip through a headed flange portion of a lamp holder to provide a liquid conduit which could potentially short the lamp. The clip is provided with legs extending from either side of the bight and each leg has a pair of spaced, parallel wing portions extending outwardly from its associated leg to expand when inserted through the mounting plate. The wing portions provide vertical shoulders to seat the lamp holder on a vertical support in conjunction with a compressible coil spring provided on the opposite side of the mounting panel or vertical support between the headed flange and support to exert pressure on the clip shoulders against the rear of the mounting panel.

Abstract: A mounting apparatus for fluorescent lamp holders in a fluorescent sign frame including a stationary and a compressible lamp holder for each lamp detachably connectable to an attachment bracket having a forward projecting pair of parallel latch tongues adapted to snap-fasten into a pair of corresponding slots in a mounting plate or raceway cover from the rear of the raceway cover.

Abstract: In an electrical receptacle having a generally hollow cylindrical section for receiving a high tension wire at one end and a neon tube at another end, said neon tube adapted for electrical connection with said high tension wire interiorally of said hollow cylindrical section, said hollow cylindrical section comprised of carbonate resin plastic for resisting sudden heat increases within said hollow cylindrical section in the region of said electrical contact with said neon tube and said high tension wire wherein said carbonate resin plastic has a melt flow of 9 to about 12 g/10 m at 300 degrees Centigrade and 1,200 g load and tensile stress at yield of 63 MPa, a tensile stress at break of 68 MPa, a delfection temperature under load at 1.8 MPa of 133 degrees Centigrade and a dielectric strength of greater than 16 KV/mm.
