Patent number: 6752611Abstract: An optical disk exhibiting no detrimental thickness increase (edge wedge effect) that arises at the outer diameter of an optical disk substrate during an injection molding manufacturing process, and an apparatus and method for making such a disk. The optical disk of the present invention is designed for use with an optical disk player, especially where the data on the optical disk is stored air incident. This optical disk includes a disk substrate made from a molded polymeric material. The disk substrate has a first major surface, a second major surface, and an outer edge. The first major surface of the optical disk includes a data region having an intermediate portion and an outer portion. The outer portion extends to the outer edge of the optical disk. The disk substrate has a thickness defined by the distance between the first major surface and the second major surface. The optical disk also includes an information layer covering the data region.Type: GrantFiled: November 15, 2001Date of Patent: June 22, 2004Assignee: Imation Corp.Inventors: Chad R. Sandstrom, Douglas R. Plourde, Dean E. Sitz, Donald J. Kerfeld, John R. Johnson

Patent number: 6723427Abstract: The present invention relates to multilayer decorative sheet comprising: (a) an outer heat resistant carrier first carrier sheet, (b) a clear coat, which in one embodiment, comprises a blend of a fluorocarbon polymer and an acrylic or methacrylic resin, coated on the carrier sheet, (c) a tie coat layer on the clear coat layer, (d) fade print coat on the tie coat layer, (e) an optional back coat on the print layer, (e) a pressure-sensitive adhesive, and (f) a second carrier sheet adhered to the pressure-sensitive adhesive. When used on a vehicle the graphic has an opaque portion, such as a metallic finish, at the topside of the vehicle and the opacity fades over the graphic to clear, thereby revealing the vehicle's color under the decorative sheet. The fading occurs across the width of the graphic. In one embodiment, the fade is gradual and reveals little stark changes in opacity.Type: GrantFiled: June 21, 2000Date of Patent: April 20, 2004Assignee: Avery Dennison CorporationInventors: John R.

Publication number: 20030041962Abstract: A process for manufacturing three-dimensionally shaped polymeric sheets and laminates with color-matched digitally printed full color ink jet images. A flexible thermoformable polymeric baseweb is placed in an ink jet printer and a solvent-based (non-aqueous) digital printing ink is applied directly to the baseweb, in the absence of an ink receptive layer on the baseweb, to form a decorative pattern in multiple colors in a single pass through the printer. The finished product can be thermoformed or injection molded to a three-dimensional shape. A protective topcoat can be laminated to the digitally printed sheet prior to the thermoforming and/or injection molding step. A process for making color-matched products comprises producing a software-driven image of a pattern on a screen representing a standard color print pattern; evaluating and adjusting the standard displayed on the screen using software-driven image related adjustments for hue, contrast, lightness/darkness, etc.Type: ApplicationFiled: September 5, 2001Publication date: March 6, 2003Inventors: John R. Johnson, Jerry Roedel

Patent number: 6349754Abstract: An interior automotive skin material has a thermoplastic resinous base coat/clear coat paint film bonded to the outer surface of a thermoplastically formable semi-rigid resinous backing sheet. The base coat/clear coat paint film is preferably formed by dry paint transfer techniques in which the clear coat layer and pigmented base coat layer are coated on a polyester carrier and dried, followed by transfer-laminating the base coat/clear coat paint film from the carrier to the backing sheet on which the clear coat layer forms a low gloss protective outer surface. The clear coat material preferably comprises an alloy of an acrylic resin and a fluoropolymer resin, preferably polyvinylidene fluoride. The low surface gloss of the outer clear coat is produced by a dispersed fine particulate filler such as silica combined with coating the outer clear coat layer on a matte carrier.Type: GrantFiled: May 11, 1998Date of Patent: February 26, 2002Assignee: Avedry Dennison CorporationInventors: John R.

Patent number: 6029921Abstract: A facial quality paper usable with a center feed roll dispenser. The paper has a plurality of perforations for permitting detachment of paper sections from the loose paper end of the roll. A linear density of six perforations or less per inch are formed along the detachment line to facilitate detachment of each paper section without permitting premature detachment of the paper section within the center feed roll dispenser. Alternatively, control over the separation strength is provided by one or more perforations comprising less than seventy percent of the base line. Separation control is provided by the number or perforations per linear inch, by the total ratio of perforations versus paper along the detachment base line, or by the perforation shape 1.Type: GrantFiled: October 29, 1998Date of Patent: February 29, 2000Inventor: John R. Johnson

Patent number: 5785274Abstract: An apparatus for containing and dispensing toilet paper. The apparatus holds the toilet paper roll in a stationary position as the loose paper end is pulled from the inner core of the paper roll. A housing for containing the paper roll is attached to a base, and a cover engaged with the housing compresses the paper roll against the base. This compression prevents sag of the layered toilet paper roll as the void in the paper core becomes enlarged.Type: GrantFiled: December 10, 1996Date of Patent: July 28, 1998Inventor: John R. Johnson

Patent number: 5641524Abstract: An apparatus for plug-assisted thermoforming of a cup or other hollow article has a concave well or cone region machined into its top with a series of small holes drilled near the deepest part of the well and connected to a port inside the plug which is connected to a specifically sized manifold system. The manifold has a source for positive (pneumatic) and negative (vacuum) pressure air. During the machine cycle, a vacuum is introduced into the plug, which draws the hot plastic sheet into the plug well to stretch it. The vacuum is replaced by compressed air to transfer the pre-stretched sheet into a mold. In a particularly preferred embodiment, the plug is shaped to provide stretching in both the central well and in peripheral regions concentric with the well. Controlled air pressure in the mold may be used to provide the concentric prestretching.Type: GrantFiled: June 7, 1995Date of Patent: June 24, 1997Assignee: James River Corporation of VirginiaInventors: Jonathan E.
