  • Patent number: 5183327
    Abstract: A fluorescent lighting fixture is provided with an assembly housing on the top thereof formed of sidewalls and a removable cover and endcaps. When the cover and endcaps are removed, sequential end-on-end placement of a plurality of the fluorescent lighting fixtures causes a channel to be formed into which a continuous common electrical power line is placed. Each ballast assembly communicates with the electrical power line.

  • Patent number: 5160193
    Abstract: The apparatus is a modular medical lighting system which includes a ceiling-mounted reading light module, examination light module, ambient light module, and a night light module. The reading light is directed toward a selected reading area on a hospital bed directly below the medical lighting system. The examination light illuminates the entire top surface of the hospital bed. The ambient light directs light to a wall abutting the head of the hospital bed thereby providing reflected light to the vicinity of the hospital bed. The night light directs light to a selected side of the bed so as to light a nurse's medical chart clipboard without disturbing the patient. The modules may be provided separately or in combination.

  • Patent number: 4760508
    Abstract: A modular light fixture is provided comprising a ballast housing, socket plate and lens assembly. The socket plate includes an inclined portion containing a socket hole and an adjacent flat portion through which mounting holes extend so that the socket may be mounted either on the incline or generally perpendicular to the flat portion. The socket assembly includes mounting means which are generally symmetrical about a horizontal axis of the plate so that either face of the plate may receive the socket. A boss containing a pin hole is provided at a corner of the plate aligned with a flange on an associated reflector housing. When the pin is in position, it prevents an inappropriate lens assembly from being positioned on the ballast housing.

  • Patent number: 4760511
    Abstract: A light fixture is provided having a mounting base and a housing. The base and housing are connected to each other by an arm that extends from a corner of the top of one to a corner of a side of the other. This arrangement permits the base to rotate with respect to the housing between a position wherein the housing is generally parallel to the base to a position wherein the base is generally perpendicular to the housing.

  • Patent number: 4716504
    Abstract: A system for securing a light fixture to a grid of a suspended ceiling is described. The fixture has a cutout at each corner of its opposed sidewalls. The cutout is formed with vertically spaced, horizontal surfaces. A bracket has a plate with upwardly extending opposed legs disposed transverse to the plate. The legs are biased away from each other and are each provided with upwardy extending surfaces adapted to capture one of the horizontal surfaces of the cutout therebetween. The bottoms of the legs define feet adapted to sit on an associated grid member. The plate extends below the grid member so that the member is captured between the plate and the upwardly extending surfaces while flanges affixed to the legs engage the inside of the fixture to provide a positive engagement between the fixture and the grid.

  • Patent number: 4626615
    Abstract: An RF expansion joint for an electrically sealed enclosure having first and second wall members which are movable relative to each other. The joint includes guide means for maintaining the wall members in alignment during movement. The wall members each have a shielding material on their outer surfaces with a shield extension extending from the shielding of one wall member and overlying the shielding material of the adjacent wall member and an electrical sealing means is positioned between the extension and the shielding material over which it lies.

  • Patent number: 4575578
    Abstract: A method of making a shielding gasket integral with a surface comprising the steps of (a) preparing a gasket material consisting of a mixture of an elastomer, a conductive filler, a catalyst and a bonding agent; (b) filling a mold with the gasket material; (c) covering the mold with a surface chosen to be bonded to the gasket; and (d) curing the gasket material in contact with the surface to utilize the bonding agent to bond the gasket material to the chosen surface. The article fabricated by this method comprises a gasket (18b), consisting of a mixture of an elastomer (26), a conductive filler (30) and a bonding agent (28), bonded to a surface (38) by the bonding agent during curing and having the particles comprising the conductive filler held in physical contact with the surface and with one another by the elastomer to which the particles are bonded.

  • Patent number: 4546944
    Abstract: A cap is provided for mounting a light fixture to a post having a longitudinal shaft of rectangular section extending therethrough. The cap includes a closure for the shaft bore having a drive cone secured to the closure and extending into the shaft interior. Fingers are mounted to the closure for transverse movement within the shaft. Each of the fingers has an inner edge abutting the cone and an outer edge adapted to engage the interior of the post when the finger is shifted outwardly. A drive screw extends through the closure and serves to drive the cone upwardly and hence the fingers outwardly.

  • Patent number: 4525595
    Abstract: A radiation resistant joint between an edge of a movable member and a corresponding edge of a fixed member. The joint comprises at least two bowed conductive contact fingers fixed at one end to one of the members with one finger superimposed over the other finger. The free end of the upper finger engages the bow portion of the lower finger. Means are provided for moving the lower finger and consequently the upper finger away from the member with which they are attached such that the bow portions of each finger engage a conductive plate on the other member to make a radiation resistant seal therewith.

  • Patent number: 4484574
    Abstract: A pressure-sensitive tape having a closed-cell polymer foam backing strip and a pressure-sensitive adhesive is disclosed. The tape is formed into a roll so that the adhesive of one layer is in direct physical contact with the foam of the next layer, without the use of release paper or release coatings. The tape may be unwound without significantly disrupting either the adhesive layer or the foam layer. The foam is preferably a closed-cell cross-linked polyethylene copolymer and the adhesive is preferably a hypoallergenic acrylic-based adhesive.

  • Patent number: 4399317
    Abstract: An electrically conductive rectangular housing contains a conductive elastomeric tube with a resilient core material. The housing also contains an inflatable seal which is preferably a flattened inflatable elastomeric member. Inflation of the elastomeric member causes the minor axis of the seal to become elongate, compressing the tube into conductive contact with sections of the enclosure and forcing a part of the tube from a slot in the housing and into contact with the surface of a conductive section of the enclosure disposed opposite the slot. Upon deflation, the seal returns to its uninflated shape due to its "memory" characteristic, thus permitting the conductive tube to withdraw from contact with the conductive section opposite the slot and assume its unextruded shape.
