Patent number: 6251965Abstract: A process for forming a surface modification on a polymer substrate and polymer substrates having such surface modifications. The process comprises the steps of absorbing a swelling monomer into the polymer substrate for a period of time in order to swell the polymer substrate; removing the swollen polymer from the swelling monomer; transferring the swollen polymer to a reaction mixture containing at least one functional monomer; polymerizing the functional monomer in the reaction mixture containing the swollen polymer substrate for a period of time; and removing the polymer from the reaction mixture. Because the surface modification produced by the process is a surface interpenetrating polymer network, the process is not sensitive to the reactive groups located on the surface of the polymer substrate. Further, the surface interpenetrating network bonds to the polymer substrate through caternary connections or other forms of chain entanglement and thus is quite stable.Type: GrantFiled: May 3, 1999Date of Patent: June 26, 2001Assignee: Pharmacia ABInventors: Yading Wang, Robert van Boxtel, Stephen Q.

The wrapper may be composed of two or more plies of packaging material such as films made from ethylene vinyl alcohol copolymer or from polyolefins such as polypropylene. In one construction, a transparent or translucent laminated wrapper becomes opaque upon rupture or puncture. In other constructions, a transparent or translucent wrapper becomes colored at the site of the rupture or puncture.Type: GrantFiled: March 18, 1991Date of Patent: August 10, 1993Assignee: Philip Morris Inc.Inventors: Ronald J. Versic, Donald D. Emrick

Patent number: 5176946Abstract: A method of manufacturing a core for an electrical inductive device. A blind hole is provided through a stack of laminations into which an oil or an epoxy resin adhesive is placed. The blind hole provides a slow release for the oil to the outer surfaces. This obviates the contamination of the outer surfaces of the coil during manufacture as in the case with a dipping procedure. When the epoxy resin adhesive is employed in the blind hole, a wicking action takes place for better fastening of the laminations together. In another embodiment of the fastening feature, epoxy resin adhesive is molded to the outside of the end piece laminations as well as through a passage in the laminations. An improved resulting core is also provided.Type: GrantFiled: May 10, 1991Date of Patent: January 5, 1993Assignee: Allen-Bradley Company, Inc.Inventor: Christopher J. Wieloch

Patent number: 5175055Abstract: A thermal transfer ink composition including a first component not having a distinct melting point below about 200.degree. C. The first component can be present as about 5 to 75% of the ink composition. The ink composition also preferably includes a second component having a melting point below about 200.degree. C. and colorant. The ink is highly resistant to extended exposure to high heat and high humidity and is capable of providing color printing with excellent color gradation and a broad range of color as well as providing a color image having a smooth look and feel. A thermal transfer ink medium includes the ink composition coated on a thin film support. The optical density of ink transferred from the medium is linearly proportional to printing energy supplied to the transfer medium.Type: GrantFiled: August 30, 1989Date of Patent: December 29, 1992Assignee: Seiko Epson CorporationInventors: Michinari Tsukahara, Makoto Taniguchi

Patent number: 5150722Abstract: Described are methods for effecting the controlled release of fragrance materials over a relatively long period of time for the purpose of air treatment and scenting. Optionally in the same time frame the methods can effect an initial "Burst" of the same or different organoleptic functional materials over a relatively short period of time. The air treatment agents can include but are not limited to insect repellents, air fresheners, odorants and deodorants. Also described are articles capable of being mass produced which are useful in effecting the controlled release of fragrances, insect repellents, air fresheners, odorants and deodorants over a relatively long period of time and, optionally, in the same time frame, effecting an initial "Burst" of the same or different organoleptic functional materials over a relatively short period of time. Also described is apparatus specifically designed to utilize such articles.Type: GrantFiled: November 9, 1990Date of Patent: September 29, 1992Assignee: International Flavors & Fragrances Inc.Inventor: Howard J.

Patent number: RE34944Abstract: Disclosed is a thermo-sensitive transfer ink ribbon to be used for producing a dry type transfer material, which is constituted by: a ribbon substrate material; an ink layer formed on a surface of the substrate material and containing a coloring agent, a binder agent, a pressure-sensitive adhesive in the form of dispersion of fine particles; and a transfer property control layer formed on the ink layer and containing a thermo-sensitive adhesive and a tackiness agent. Further disclosed is a method of producing the thermo-sensitive transfer ink ribbon which comprises the steps of: dissolving/dispersing a coloring agent, a binder agent, and a pressure-sensitive adhesive in a predetermined solvent; applying the solvent onto a surface of a ribbon substrate material so as to form an ink layer on the surface; and coating the ink layer with a mixture in which a thermo-sensitive adhesive and a tackiness agent are mixed with each other in the form of a predetermined solution or dispersion liquid.Type: GrantFiled: November 23, 1992Date of Patent: May 16, 1995Assignee: Brother Kogyo Kabushiki KaishaInventor: Mitsuo Yamane
