  • Patent number: 5523932
    Abstract: A lighting fixture with an adjustable reflector that will move to many different positions relative to the lamp and can be installed without tools and adjusted between positions with only one hand. The invention operates with an outwardly facing set of V-shaped notches at a first end of the lamp which mate with and an inwardly facing set of biased fingers at a first end of the reflector. The reflector is adjusted by manipulating it in a radial direction, thereby causing the biased fingers of the reflector to move across the V-shaped notches at the first end of the lamp.

  • Patent number: 5453029
    Abstract: A molded connector has a contact support made of a material which is chemically compatible with the molded body and has a similar melting point. The contact support is provided with thin fins which provide a barrier around each of the contacts. As the molded material is injected around the contact support and contacts, the fins melt and fuse to the surrounding material, thereby isolating the contacts from each other.

  • Patent number: 5449302
    Abstract: The present invention serves to prevent severe injury, loss of life or damage to expensive equipment by creating a system in which the conductors of a plug and the conductors of a receptacle can only be arranged, one with respect to the other, in a unique rotational manner depending upon the intended electrical rating of the plug and receptacle. The resulting plug will mate only with a receptacle having that same configuration. A separate indexer is disposed between the plug body and the conductor assembly to the conductors in the plug to prevent entry of the plug into a differently indexed receptacle. A polarizer in the receptacle fixes the conductor assembly of the receptacle in the same manner as the plug, to allow the plug and receptacle to be mated together when the receptacle is wired for the same electrical rating as the equipment to be energized by the plug.

  • Patent number: 5442980
    Abstract: A nut drive adapter for use with a power tool includes a splined driven end located coaxially with a square drive. Changing the size of the square drive used with power tools requires only changing the nut drive adapter rather than changing the entire drive housing.

  • Patent number: 5439063
    Abstract: A compressed-air screw or bolt tightener having a driving motor which drives a driving shaft for a screwing or tightening tool is disclosed. The motor is operated by compressed air and a control valve for switching the compressed-air supply to the screw or bolt tightener on or off. A pressure-regulating valve is used to regulate the kinetic energy of the screw or bolt tightener.

  • Patent number: 5406448
    Abstract: A hanger for a power factor capacitor and method of attachment by brazing reduces metallurgical changes that can lead to cracks in the tank wall from welding. The hanger has a base plate with a circular opening and a raised shoulder that provides a single ring of contact between the tank wall and hanger. A ring of brazing alloy is placed within the opening on the tank wall. Through induction of electric current, the brazing alloy melts and flows resulting in a complete braze between the hanger and the tank wall which is accomplished at a much lower temperature than other welding techniques.

  • Patent number: 5381773
    Abstract: A modular system for providing electrical power to the input contact of an engine igniter is constructed within a hollow container. The container includes a space for mechanically mounting and providing electrical power to the igniter. When the igniter is placed within the hollow container, electrical contact is made between the exciter module and the engine igniter.

  • Patent number: 5330201
    Abstract: A sealing assembly for sealing between two relatively rotatable cylindrical surfaces. The assembly comprises two seal parts (46, 48) disposed in a groove (40) in one of the surfaces so that one of said parts is disposed radially outwardly of the other. One (46) of the parts is movable axially relative to the other (48) to effect setting of the sealing assembly and the groove (40) and parts (46, 48) are so dimensioned that they become compressed between the surfaces during setting of the assembly. Adjacent surfaces of the seal parts (46, 48) may have inter-engaging profiles (55) which permit relative movement for setting the assembly, but resist movement in the opposite direction.

  • Patent number: 5330002
    Abstract: A hanger (3) is suspended and sealed within a wellhead housing (5) by means of a landing ring which engages teeth (8) on the hanger, and a sealing device consisting of wedge rings (15 and 16) which seal respectively against the teeth (8) and the wall of the housing (5).

  • Patent number: 5326285
    Abstract: A connection system between terminal blocks whereby one block has an extension and one block has a mating pocket. Upon connection, the various surfaces of the extension and pocket cause a frictional relationship between the blocks and maintain a uniform distance between the termination points around the connection.

  • Patent number: 5305814
    Abstract: An improved method for draping curtains which allows one person to form a decorative window treatment known as a bishop tail without requiring any specialized skills or training. The method described hereinafter allows a fabric scarf to be draped from a rod of conventional configuration in a decorative manner about a window opening. The method uses hook and loop type fasteners means to secure the fabric scarf to the rod and thereby prevent the fabric scarf from sagging at the top. Curtain rings are placed over the ends of the depending fabric scarf and then installed on the rod near its ends to allow a portion of the fabric scarf to form a decorative downwardly curved arc of fabric. The newly formed arc is then "dressed" or folded into pleats in accordance with the teaching of U.S. Pat. No. 5,146,972 to William L. Tacchella. A hook closure ring is then installed through the previously hemmed edges of the fabric scarf and hung by a cord from the wall bracket to form the bishop tail.

  • Patent number: 5281056
    Abstract: An indexing coupling for a drill includes a hollow inner race, a hollow outer race, and a sleeve member. The hollow inner race and hollow outer race are affixed to one another by a plurality of ball members which are positioned by a plurality of detents in the hollow inner race. The balls also extend into holes in the hollow outer race. When the balls are positioned within the holes in the hollow outer race and within the detents in the hollow inner race by the sleeve member, the hollow inner race and the hollow outer race are rigidly connected one with respect to the other. When the sleeve member is moved the ball members become disengaged from the hollow inner race thus allowing indexing of the outer race with respect to the hollow inner race. This indexing of the hollow outer race with respect to the hollow inner race allows selective rotatable indexing of the drill housing with respect to the nose piece.

  • Patent number: 5280261
    Abstract: An arc quenching, current limiting fuse utilizing a fuse link having a plurally of bends which cause the fuse link to come in contact or come in close proximity to the inside wall of the fuse body. When a short circuit and electrical arc occurs, the fuse link material burns toward the fuse wall creating an interaction with the fuse wall and an increase in pressure which extinguishes the arc.
