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.

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.

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.

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.

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.

The photo media has a gloss value at 60° of less than about 25%, an adhesion to polyester of less than about 200 gram/inch and a static angle test adhesion value of greater than about 600 seconds.

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.

Abstract: A method for forming a complex hole through a wall of a structure. The complex hole has a smaller cross-sectional area within the wall and an outer portion with a larger cross-sectional area adjacent a first surface of the wall. The complex hole further has an inner portion extending between the smaller cross-sectional area and an inlet opening on a second surface of the wall. The method uses an EDM process to automatically first, form an entry hole in the wall extending from the first surface to a first location inside the wall, and second, form the outer portion of the complex hole in a direction moving from the first location inside the wall toward the first surface, and third, form the inner portion of the complex hole.

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.

Abstract: A hole inspection system having a light source emitting light over its length and a multi-axes machine having a camera mounted thereon. After the light source is inserted into a cavity intersecting the complex holes, a control commands the multi-axes machine to move the camera to an inspection position associated with one of the complex holes. The control processes substantially only light intensity values received from the camera that represent light shining through the one of the complex holes. Next, a maximum intensity value of light received by the camera from the one of the complex holes is determined. The maximum intensity value is compared to a threshold value, and error data is created that identifies the one of the complex holes in response to the maximum intensity value being less than the threshold value.

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.
