The thermoplastic resin film can be fused to the outer surface of the container for printing purposes and/or to create a barrier and/or can be fused to the base surfaces of the container. The molding machine used to form the foam container is used to fuse the film to the container.Type: GrantFiled: December 20, 2002Date of Patent: August 7, 2007Assignee: NOVA Chemicals Inc.Inventors: Jiansheng Tang, Jeffory E. Russell, David Allen Cowan, Michael T. Williams, Dennis H. Piispanen, John C. Kwok

Patent number: 7246467Abstract: A compressible seal for a loading dock includes a pliable heat shield that helps protect the seal from concentrated heat generated by a truck's taillight being pressed against the seal. The seal includes a compressible foam core protected by a tough outer covering. The heat shield is preferably placed against the foam core, just underneath the cover. The shield reflects heat away from the foam and helps disperse the heat over a broader area to reduce the peak temperature of any hot spots.Type: GrantFiled: April 13, 2000Date of Patent: July 24, 2007Assignee: Rite-Hite Holding CorporationInventors: Jason D. Miller, David J. Hoffmann, Charles J. Ashelin

Patent number: 7172575Abstract: A balloon for a catheter and a method of making the balloon, having a layer of a porous polymeric material with a modified outer surface and a lubricious coating bonded to the modified outer surface. In one embodiment, the modified outer surface is formed by a polymer impregnated in the porous polymeric material, and the subsequently applied lubricious coating bonds to the impregnating polymer. In another embodiment, the modified outer surface is formed by a functionality deposited on the porous polymeric material which bonds to the subsequently applied lubricious coating. The modified outer surface provides an improved strong bond between the lubricious coating and the balloon, for improved catheter performance.Type: GrantFiled: March 5, 2003Date of Patent: February 6, 2007Assignee: Advanced Cardiovascular Systems, Inc.Inventors: Fozan El-Nounou, Timothy Owens, Florencia Lim, Edwin Wang

Patent number: 7169265Abstract: A method for manufacturing resin-impregnated endless belt structures and belt structures designed for use on a long nip press on a papermaking machine and for other papermaking and paper processing applications, requires the application of a sacrificial material onto a base substrate in a predetermined pattern in droplets having an average diameter of 10? (10 microns) or more. Polymeric resin material is then deposited on the base substrate to cover all areas except those on which the sacrificial material has been previously applied. The polymeric resin material is then set by means appropriate to its composition, and the sacrificial material removed. Optionally, the polymeric resin material may then be abraded to provide the belt with a uniform thickness, and a smooth, macroscopically monoplanar surface.Type: GrantFiled: December 31, 2002Date of Patent: January 30, 2007Assignee: Albany International Corp.Inventors: Charles E. Kramer, Joseph G. O'Connor, Maurice Paquin

Patent number: 7157139Abstract: A process utilizing PET as a reactive constituent to manufacture other polymers containing the pre-condensed moieties by the rapid transesterification of the condensation polymer with a pre-made modifying polymer containing the desired mix of other monomers. The process involves as a first step the manufacture of a modifying polymer containing the desired mix of acids and alcohols to a specific molecular weight such molecular weight dependent on the desired final level of utilized condensation polymer and the finished molecular weight. The second step of the process involves the rapid buildup of molecular weight and/or polymer uniformity by the rapid transesterification of the condensation polymer with the modifying polymer. The second step can be performed in any suitable vessel including an extrusion line. The process has the advantage of greatly reduced cycle times over other condensation polymer utilization processes such as the recycling of PET into other materials.Type: GrantFiled: April 19, 2004Date of Patent: January 2, 2007Inventors: Keith Salsman, Grant Doney
