Abstract: A method or process for treating materials for making materials electrically conductive that are not naturally electrically conductive or for increasing and enhancing the electrical conductivity of materials that are naturally electrically conductive. The invention is carried out in processing apparatus or equipment. The apparatus includes a vessel containing a solution that is electrically conductive. The solution or bath contains salts including acid surfactant, acid and silver nitrate crystals. The apparatus includes electrical equipment which includes electrodes exposed to the solution in the vessel so that an alternating electrical current is caused to traverse the solution and the material being processed. Additionally, the apparatus includes an array of ultrasonic generators provided to cause ultrasonic sound vibrations to traverse through the solution and the material being processed simultaneously with the flow of current.

Abstract: A grounding system for grounding a static dissipative surface or an object that is static dissipative. A bolt is provided that extends through a hole or bore in the product wherein a static charge is to be grounded. A unique form of head is provided which is conical in shape and is adapted to fit into a conical counterbore to assure that connection is made for electrical conductivity. In one form, a fitting serving as a nut is utilized, which is preferably round and knurled, to provide ease of finger tightening. The outer surface of the conical head is knurled to assure an electrical grounding connection. In a second form of the invention, the head has a bore extending through it with a tapered counterbore which receives the tapered head of a bolt which comes flush with the flat upper surface of the head. Ordinary nuts and washer may be used on the stem of the bolt.

Abstract: A product which is one having a static-free grounded work surface. There is a first component which is a relatively thick particle board but of a predetermined thickness. Overlying the particle board is wire mesh screen of particular gauge mesh with its edge portions secured to peripheral parts of the particle board. Overlying the wire mesh screen is a relatively thin plastic sheet of melamine which provides the working surface. A static charge is dissipated through the plastic laminate and through the wire mesh screen to ground connections.

Abstract: An article of manufacture which is a conductive floor tile for control of generation of static electricity and method of installation. The tile includes a thin, hard layer of plastic material having bonded to it a lamination which is an electrically conductive mesh screen which is bonded to the top surface lamination by an electrically conductive adhesive. The product is a tile, the tiles being adapted for being bonded to a surface adjacent to each other with electrically conductive strips positioned beneath the joints between adjacent tiles to provide electrical continuity. The method includes the fabrication of the tiles and the steps in the installation of the tiles as described by being bonded to a surface or subsurface.

Abstract: A conductive laminate product capable of dissipating static charges and adapted for use on vertical and horizontal surfaces. The laminate product is formed of a thin, hard layer of plastic material, a thin layer of metallic foil which is electrically conducted, bonded to the top layer by way of an electrically conducted adhesive material and a layer of backing material secured to the metallic foil.

Abstract: A table or platform with an improved conductive top adapted for use particularly with small electronic parts. The table or platform includes a normally horizontal top surface. An improvement in one form of the invention is provided by way of stretching a metal screen or mesh material across the top and then filling the mesh with a layer of resin. The resin is ground or sanded off to expose the mesh to provide the conductive top. The conductive top is grounded. Appropriate grounding means are provided to accommodate the grounding. In a second form of the invention the conductive top is provided by way of embedment of metal particles in a plastic layer so as to make the layer conductive. Preferably the table or platform is fabricated by an improved method embodying the placement of plural layers of resin embedding the wire mesh material, screeding, sanding, and polishing to provide a smooth surface wherein the metal of the mesh is exposed.

Abstract: The invention is an improvement in mechanisms or apparatus for transporting articles or products between points such as work stations in an industrial plant or the like. A track or trackway is provided running between different points or work stations, the track provides fixed rail members. A truck or trolley equipped with rollers on its underside is movable on the trackway between different points or work stations, the trackway being supported at spaced intervals. The truck or trolley is provided with wheels or rollers that are engageable with the track. The truck or trolley is provided with additional wheels positioned so that the truck can move at right angles to the track into a shunt position at a particular work station. Articles such as devices being produced can thus be very readily moved about from one point to another, that is, from one work station to another in a plant area.

Abstract: A production workbench is associated with a production cart which is mounted on castors to be movable from one work station to another. In a preferred form, the bench is provided with a slot or cutout to receive the production cart. Inter-engaging guide track apparatus and rollers are provided between the bench and the cart operative to serve as self-leveling apparatus to bring the surfaces of the bench and the cart to the same level when the production cart is inserted into the cutout.

Abstract: The invention relates to the construction of metal articles such as work benches, pallet racks, etc., by way of example. In a typical construction upright hollow metal legs are secured to a flat table or platform surface. The upright members or legs preferably may be square in cross section. The upper ends of the legs are secured to mutually perpendicular transverse members which in turn are secured to the flat platform surface. The transverse members are preferably channel shaped with side flanges. An end plug or fitting is inserted into the upper end of each leg, the fitting being tapped to receive stud bolts. The ends of the transverse members are secured to the legs and the end plugs by stud bolts.

Abstract: An in-depth storage device where fixed shelves are supported on a plurality of vertical uprights and a sliding shelf is used in conjunction with each of the fixed shelves to provide in-depth storage space. The sliding shelves may be moved either manually or by powered mechanical means horizontally so as to align the leading edge of the sliding shelves with the leading edge of the fixed shelves. The track means upon which the sliding shelf is movable consists of a pair of channel beam members forming a simple beam connection between the fixed shelf members. Each channel beam carries a plurality of rollers which are mounted to the vertical flange of the channel beam within the channel portion of said beam. The sliding shelves are supported by an I beam, the lower flange of which engages the rollers which are mounted within the channel beams.

Abstract: The invention relates to the construction of metal articles such as work benches, pallet racks, etc., by way of example.In a typical construction upright metal legs are secured to a flat table or platform surface. The upright members or legs preferably may be square in cross section. The upper ends of the legs are secured to mutually perpendicular transverse members which in turn are secured to the flat platform surface, the members being joined by self tapping screws. The transverse members are flat with side flanges which terminate short of the ends the end portions of the flanges being bent inwardly to provide mutually perpendicular securement tabs. The ends of each of two transverse members have securement to 2 flat sides of the end part of the square legs.
