  • Patent number: 7841379
    Abstract: Method and apparatus for pumping molten metal from a reservoir into a preferably bottom-filled mold includes a pair of graphite pump crucibles partially submerged in a reservoir of molten metal. Check valves in the bottom of each crucible enable them to be filled to the same level as the reservoir. A high pressure inert gas supply operating through a pressure regulator, forces the molten metal from one of the crucibles up a riser tube to a horizontally extending runner and through a fill port into the mold. The pressure supply is then connected to the other crucible while the first refills.

  • Publication number: 20070147712
    Abstract: The present invention relates to methods of making articles for storing and organizing materials. One method includes the steps of (1) providing first and second panels that are substantially similar in geometry as defined by a perimeter, each panel having opposing inside and outside surfaces; (2) cutting an opening in the first panel; (3) attaching the first and second panels along their perimeters such that the inside surface of the panels are proximate to each other; and (4) applying means for attaching the article to a display surface on at least a portion of the outside surface of the second panel.

  • Publication number: 20070138044
    Abstract: The present invention relates to an article for storing and organizing materials. The article has opposing front and rear panels. Each panel has an inside surface and an outside surface. The panels are substantially similar in geometry as defined by a perimeter. The panels are joined substantially along the entire perimeter such that at the inside surface of the front panel is proximate to the inside surface of the rear panel. An opening disposed within the front panel away from the perimeter. Finally, an adhesive disposed on at least a portion of the outside surface of the rear panel. A stack of a plurality of the articles is also provided.

  • Patent number: 7213634
    Abstract: An offset mold process deflects a mold assembly being conveyed along a first path laterally of that path into engagement with a nozzle using a shuttle car. Molten metal is pumped into the mold assembly, which is either a cope and drag mold or a lost foam mold, from below the molded part to eliminate eddy currents which can create incongruities in the molded part. One method of flow cutoff involves movement of a first mold component relative to the bottom board cuts off the flow of molten metal and locks the mold fill in the mold assembly. A second method of flow shutoff usable in the lost foam process involves the engagement of a flow cutoff plunger to cut the flow stream once filling the mold has been completed. In both the cope and drag and lost foam apparatuses, withdrawal of the shuttle car enables molten metal in the feed line to drain into a catch ladle obviating the need to burn embedded sand from the scrap prior to its recycling into the melt.

  • Publication number: 20070089832
    Abstract: The present invention provides a matte repositionable photo media has an imageable substrate having opposing first and second surfaces. An image receptive coating is disposed on the first surface of the inkjet printable sheet. A repositionable adhesive is disposed on the second surface of the substrate, but the adhesive does not cover the entire second surface. A liner is disposed on the second surface of the substrate. The photo media has a gloss value at 600 of 25% or less, an adhesion to polyester of 200 gram/inch or less and a static angle test adhesion value of greater than 600 seconds.

  • Publication number: 20060134363
    Abstract: The present invention relates to a composition composed of a crosslinkable resin containing lactam groups; a DMAPMA/HEMA copolymer copolymer; and a cellulose based water absorbent polymer. The invention also relates to a printable substrate composed of a substrate, optionally, a layer serving as a base layer; and at least one layer derived from a composition as defined in the present invention. Process for preparing such a printable substrate is also provided.

  • Publication number: 20050271849
    Abstract: An assembly includes a plurality of repositionable devices. Each repositionable device includes a first major surface and a second major surface opposite the first major surface. A coating of adhesive material is applied on at least a portion of the second major surface of each repositionable device. The repositionable devices are releasably adhered to each other by adhesion of the coating of adhesive material on one repositionable device to portions of the first major surface of an underlying repositionable device. The repositionable devices are arranged in a shingled stack relation.

  • Publication number: 20050142341
    Abstract: A method for imparting graphics to a substrate comprises imparting an image to an image carrier sheet comprising an image receptive layer disposed on a carrier sheet. A substrate having a microstructured pressure sensitive adhesive layer disposed on at least a portion of a surface thereof is provided. The image carrier sheet is brought into contact with the adhesive layer of the substrate. Pressure is applied to the image carrier sheet such that one of the carrier sheet and the image receptive layer is adhered to the adhesive layer of the substrate. This method can be utilized for substrates that cannot be easily imaged directly by using, e.g., a conventional ink jet or laser printer.
