  • Patent number: 7296677
    Abstract: A package includes a stack of hinged trays for holding media discs, having a flexible hinge member affixed to the hinge edges of the trays, mounted in a protective container having a base, a spine and a cover. The bottom tray in the stack is mounted in the base for pivotal movement about the tray edge opposite the hinge edge, whereby, as trays are pivoted about the flexible hinge member from the stack onto a second stack, the hinge edge of the bottom tray pivots away from the base when the second stack contains at least one more tray than the original stack. Pivotal mounting is achieved by providing a slot on the bottom tray which engages slot receiving means mounted on the base.

  • Patent number: 5597447
    Abstract: A method is disclosed for producing, in a continuous throughput, high quality paper from recycled waste paper utilizing high consistency, low shear pulping, followed by a series of cleaning steps to produce a wet, friable pulp which is digested and optionally bleached. The resulting pulp can be run on a paper machine alone or blended with virgin pulp to produce a paper containing at least 5 by weight recycled paper with less than 20 ppm per unit area solid non-fibrous contaminants larger than 0.3 mm.sup.2, and which may be blade coated on a high speed paper machine. A blade coated paper produced by the method is disclosed.

  • Patent number: 5587048
    Abstract: A method is disclosed for producing, in a continuous throughput, high quality paper from recycled waste paper utilizing high consistency, low shear pulping, followed by a series of cleaning steps to produce a wet, friable pulp which is digested and optionally bleached. The resulting pulp can be run on a paper machine alone or blended with virgin pulp to produce a paper containing at least 5% by weight recycled paper with less than 20 ppm per unit area solid non-fibrous contaminants larger than 0.3 mm.sup.2, and which may be blade coated on a high speed paper machine. The pulp and paper produced by the methods are also disclosed.

  • Patent number: 5538594
    Abstract: A method is disclosed for producing, in a continuous throughput, high quality paper from recycled waste paper utilizing high consistency, low shear pulping, followed by a series of cleaning steps to produce a wet, friable pulp which is digested and optionally bleached. The resulting pulp can be run on a paper machine alone or blended with virgin pulp to produce a paper containing at least 10% by weight recycled paper with less than 20 ppm per unit area solid non-fibrous contaminants larger than 0.3 mm.sup.2, and which may be blade coated on a high speed paper machine.

  • Patent number: 4968387
    Abstract: The lateral edges of a papermachine forming fabric pond are contained by a deckle board having a bottom edge positioned above the forming fabric upper surface elements but below the fabric supported stock pond surface. Lateral edges of the forming fabric run under the deckle board and upon an edge support beam within an elongated fluid channel between the outside surfaces of the deckle board structure and the inside surfaces of the edge support beam. Fluid flow within the elongated fluid channel, preferably independent of the papermachine headbox slice opening, supplies the elongated fluid channel volume for a fluid barrier to pond stock loss under the deckle board bottom edge.
