  • Publication number: 20140102629
    Abstract: An appliqué having anti-corrosive adhesive is provided by embodiments of the present invention. This appliqué includes a thin polymer film and a pressure sensitive adhesive. The pressure sensitive adhesive hacks the thin polymer film and includes corrosion-inhibiting additives. These corrosion-inhibiting additives reduce or eliminate the need for a chromated primer layer beneath the appliqué. Elimination of a chromated primer layer has environmental advantages as well as cost benefits through the elimination of a processing step. Additionally, environmental benefits are realized by eliminating the toxic effects often associated with the use of chromated primers.

  • Publication number: 20040065989
    Abstract: A motionless conduit vise is disclosed to include a base in which one or more receiving channels are provided. Each of the channels are sized to be slightly less than the outer diameter of the conduit to be held therein and thereby frictionally hold the conduit against linear or rotational movement once secured. A plurality of mounting structures is also disclosed so as to facilitate provision of the vise on a variety of work surfaces, such as moveable carts, pails, and ladders.

  • Patent number: 6270094
    Abstract: A wire dispensing utility cart adapted to carry wire spools for dispensing wire during installation. The present invention provides a relatively large utility cart for carrying multiple and large spools of wire in a mobile fashion for dispensing wire during the installation of electrical wiring into buildings, structures, aircraft, and the like. The cart is mobile and relatively compact to facilitate movement of the cart through standard sized doorways and elevator bays, and is sufficiently large to accommodate a large number of wire spools. In addition, the cart provides at least two elongated storage bays to facilitate transportation of relatively large objects such as ladders, conduits, and other materials and supplies needed for the installation process.

  • Patent number: 6241181
    Abstract: A reusable spool for use in installing electrical wiring is provided. The spool may include first and second mating halves, each having an end plate and a central mandrel. The mandrel of one half may be inserted into a wound coil of wire, which can then be overturned to allow the second half to be connected to the first half. The first and second halves may be joined through a plurality of arcuate longitudinal tabs which slidably engage in one position to adjust width, and upon rotation, lock frictionally into a given position.

  • Patent number: 5915646
    Abstract: A cart adapted to carry utility trays for tools, fasteners, materials, and a plurality of wire spools from place to place. The cart include racks for selectively holding spools and trays. The cart can be translated between upright and substantially horizontal positions without emptying the contents in the tray onto the ground. The tray is pivotally supported by the cart so that the tray remains upright as the cart is translated between upright and substantially horizontal positions. The cart is also supported by an increased base provided by an extension plate extending forwardly from the cart, to thereby provide greater stability and facilitate use of the cart with relatively large diameter wire spools.

  • Patent number: 5509671
    Abstract: A cart is adapted to carry spools of electrical wire to enable a variety of different types and gauges of wire to be transported from place-to-place. The cart includes racks for holding the spools, each rack being sized to typically hold three or four spools. The racks are releasably secured to and selectively removable from the cart to enable the spools on the racks to be carried to a site which is remote from the cart.

  • Patent number: 5156887
    Abstract: A method for injecting a chemical barrier into a surface aperture is provided. The method provides a vacuum to a work site to evacuate the air from the work site. Then, an injector head is located and retained at the work site. The injector head has a gasket that forms a seal around the work site. Pressurized fluid is conveyed to the work site through a first conduit in the injector head. Any unused fluid is conveyed away from the work site by a second conduit in the injector head.

  • Patent number: 5073224
    Abstract: A barrier injection apparatus for injecting a barrier at a site characterized by a holder for holding the apparatus in place against the force of injection; at least one injector for injecting a medium for a barrier at the injections site when in place; respective conduit system extending from the storage unit, and including a pump for inducing pressure onto the medium, to the injection site for injecting the medium at the injection site under pressure; storage unit for storing the medium at atmospheric pressure and being connected with a suction side of a pump that will introduce pressure; a second conduit connected with the barrier injection apparatus and adapted to remove unused medium from the site, an adjusting mechanism for adjusting the injectors to a correct distance; and a gasket sealingly surrounding the injection site for constraining the medium to flow into the site under pressure and insulate the medium from a holding mechanism. Also disclosed are specific preferred embodiments.

  • Patent number: 4676971
    Abstract: A method is disclosed for reducing alkali metal chlorate impurities in an aqueous alkali metal hydroxide solution by heating a mixture of the alkali metal hydroxide solution with a hydroxycarboxylic acid or a salt thereof at temperature above about 125.degree. C. and for a period of time sufficient to substantially eliminate the chlorate, the hydroxycarboxylic acid or salt thereof being substantially non-volatile at the heating temperature.
