Patent number: 6756095Abstract: This invention relates to a heat-sealable laminate, comprising: a facestock having an upper surface and a lower surface; a heat-activatable first adhesive layer underlying the lower surface of the facestock; and a second adhesive layer overlying the upper surface of the facestock, with the proviso that the laminate is characterized by the absence of either an adhesion promoting layer or an abrasion-resistant transparent coating layer positioned between the upper surface of the facestock and the second adhesive layer. These heat-sealable laminates may be used in providing pictorial and/or print designs or messages (e.g., labels, decals, etc.) that can be adhered to substrates (e.g., metal, plastic, leather, paper or textile substrates) such as automotive interior surfaces, hard plastic component parts, consumer durable goods, and the like.Type: GrantFiled: January 10, 2001Date of Patent: June 29, 2004Assignee: Avery Dennison CorporationInventors: Richard L.

Publication number: 20040105976Abstract: A coloured tape arranged for attachment as individual tabs to a paper stock file folder is formed by providing a base film and applying to the base film a first layer comprising a laminating adhesive containing the colouring agent from which the solvents are driven off. When dried, a hot melt adhesive is applied to the laminating agent and chilled. The tape is wound into a roll. At an end use location the tape is cut into tabs and the tabs applied to the paper stock using the hot melt adhesive by heat or by pressure sensitive action to cause the bond to the paper. The application of the colouring agent to the laminating adhesive allows ready admixture of the liquid colouring agent or dry pigments using the solvents in the laminating adhesive. As the colouring agent is immediately adjacent the base film, it is readily visible through the base film as a bold colour.Type: ApplicationFiled: October 29, 2003Publication date: June 3, 2004Applicant: KT Holdings Ltd.Inventor: Kenneth A.

Patent number: 6743601Abstract: An apparatus and process for the micro juxtaposition is set forth where a selectively activatable surface is maintained spaced apart from the tissue sample and juxtaposed to the tissue sample by activation. In the typical case, activation occurs by laser radiation with the material of the activatable surface thermally expanding and bringing about the desired micro juxtaposition. The disclosed micro juxtapositioning can cause locally and microscopically pressure on tissue sample, insertion to the tissue sample, or contact of an activated or prepared surface to the tissue sample.Type: GrantFiled: December 6, 1999Date of Patent: June 1, 2004Assignee: The United States of America as represented by the Department of Health and Human ServicesInventors: Robert F.
