  • Patent number: 6355121
    Abstract: A method of controlling bulk absorption of atomic hydrogen and facilitating degassing of hydrogen from aluminum alloy workpieces during heat treatments in furnaces with ambient and/or moisture-laden atmospheres to prepare for fabrication in sequential working stages, the method includes exposing the surface of the workpieces to an etching process after each or any of the sequential working stages, and subjecting the workpieces to a final etch treatment using an inorganic alkaline or acidic etch solution modified by an addition of five to twenty-five weight percent transition metal chloride salt before being subjected to said heat treatment. The workpieces exposed to the transition metal chloride salt modified etch solution are subjected to the heat treatment. The etch solution is used to substantially decrease the amount of atomic hydrogen entering the bulk of the workpieces and to facilitate removal of atomic and molecular hydrogen from the bulk of the workpieces during the heat treatment.

  • Patent number: 6220877
    Abstract: A monolithic terminal interface for supporting, and establishing electrical contact to, components such as relays and fuses includes a terminal board fabricated from a self-supporting sheet of resilient, electrically insulating material. The terminal board includes one or more terminal sockets, each being defined by a terminal slot formed through the board. The terminal slot creates opposed contact beams which include contact portions spaced by a distance less than the thickness of a terminal. The contact portions of the contact beams engage a terminal inserted therebetween, and because of the resilient nature of the material of the board, maintain contact pressure with the terminal. A pattern of metalization extends across at least one face of the board and into the terminal slot so as to cover the contact regions in this manner, electrical contact can be established through the conductive metal pattern to a terminal inserted in the slot.

  • Patent number: 6206577
    Abstract: A new and unique connector adapter shutter door assembly retrofitable to many existing connector adapters or receptacles which becomes a part of the same by connectedly fitting or snapping into place. The shutter door assembly can be used as a safety device to prevent laser light from escaping when a connector is removed from an adapter or receptacle. Because of the ease with which the shutter door assembly can be retrofitted to existing adapters, it is possible to selectively install the shutter door assembly only when a safety hazard is present. Also the shutter door assembly can be used to shield a connector end to prevent foreign matter, such as dust and dirt, from entering the connector. The shutter door assembly is a molded one-piece structure and has inwardly hinged doors permitting one hand connector insertion and withdrawal. The streamline design of the shutter door assembly takes very little space when in use making it desirable for typical space constrained applications.

  • Patent number: 6135398
    Abstract: An easily installable, robust device capable of securing and supporting cable even under extreme weather and loading conditions. The device supports cable during and after stringing of the cable. The device is easily adaptable to accommodate a large range of cable diameters and can be mounted to a variety of support structures.The device includes a body and cap formed via die casting. A non-machined hinge mechanism that is die cast as a portion of both the body and the cap connects the same and allows the device to be mounted as a single unit to a support structure. A two piece grooved elastomer bushing seats in the body and cap to surround and cushion the cable extending through the device. By altering the size of the grooves of the bushing, various diameter cable can be accommodated.Side walls having windows formed on the body of the trunion help facilitate distribution of the load of the cable.

  • Patent number: 6120618
    Abstract: A method of controlling bulk absorption of atomic hydrogen and facilitating degassing of hydrogen from aluminum alloy workpieces during heat treatments in furnaces with ambient and/or moisture-laden atmospheres by exposing the surface of the workpieces to a low molecular weight solution or dispersion of an alkyl phosphonic acid, an olefinic phosphonic acid or an aryl phosphonic acid before subjecting the workpieces to heat treatments. The workpieces exposed to the phosphonic acid solution or dispersion are subjected to heat treatment in furnaces having ambient or moisture-laden atmospheres. The solution or dispersion involves chemical species that are deposited onto the aluminum surface from the phosphonic acid solution or dispersion which substantially decrease the amount of atomic hydrogen entering the bulk of the workpieces from their surfaces during heat treatment and, in addition, facilitate removal of atomic and molecular hydrogen from the bulk of the workpieces during heat treatment.

The tool is provided with a relatively narrow pin extending from the working end of the tool to engage the workpiece edges. The tool and pin are rotated to heat the workpiece edges, and the tool and workpieces are relatively moved. Electric current is supplied between the workpiece edges and the pin, with electrical resistance occurring between the workpiece edges and pin to provide heat in addition to the heat generated by friction occurring between the pin and workpieces to weld the workpieces together.

  • Patent number: 5750453
    Abstract: A method for making a synthetic mixed metal oxide or meixnerite which, when activated, has a high B.E.T. surface area, typically about 290 m.sup.2 /g or greater. The method comprises activating hydrotalcite, then cooling and hydrating such activated material with a metal salt solution in a carbon dioxide-free environment. Such hydration can produce a material that absorbs more than 100% of its weight in water. Following hydration, this material is activated a second time in a virtually carbon dioxide-free environment. Such reactivation decomposes the salt and leaves a supported metal oxide readily available to be used for catalyst reactions.

  • Patent number: 5740602
    Abstract: A method and apparatus for making wire harness. The apparatus includes the use of a sequential wire processor that serially and sequentially fabricates circuits having terminal ends. The terminated circuits are transferred by a transfer means to an upstanding carousel provided with arrays of circuit-receiving clips. The transfer means receives terminated circuits from the sequential wire processor and places them on the clips of the carousel. The carousel is then moved to an assembly line and robotic station where robots remove the circuits from the clips of the carousel and place the terminated ends of the circuits in cavities of connectors strategically located on the assembly line. The robots have end effectors that physically insert the terminal ends into the connector cavities.

  • Patent number: 5729644
    Abstract: A multi-fiber receptacle that aligns and mates an MT or similar multi-fiber ferrule of a connector to an active device or to a lightguide means. The receptacle contains a lower chamber that houses a lightguide means that may be provided on a circuit board containing electronic components needing connection to the outside world via optical means. Above the lower chamber, the receptacle has an upper chamber which receives a connector employing a multi-fiber ferrule. The receptacle and connector are designed such that when the connector is received by the upper chamber, the ferrule fits into the lower chamber and is automatically aligned and mated with the lightguide means. Further, the receptacle and connector can be keyed in a manner that limits reception of a transmitter connector in a transmitter receptacle and a receiver connector in a receiver receptacle. The transmitter and receiver receptacles are preferably identical except for the keying feature.
