Patent number: 6793754Abstract: A covered roll is disclosed. Under an exemplary embodiment, the covered roll includes a roll core base, an under-layer formed of densely packed fibers and a covering layer. The under-layer, which may include straight and directionally oriented fibers, is infused with a thermoset resin and circumferentially surrounds the roll core base. The covering layer, which may be formed of a rubber, urethane, thermoset resin or other plastics, circumferentially surrounds the under-layer. The resin infused under-layer provides improved strength to the resulting covered roll and improves adhesion between the covering layer and the metal roll core.Type: GrantFiled: November 28, 2000Date of Patent: September 21, 2004Assignee: Advanced Materials CorporationInventor: Yang T.

Publication number: 20040089397Abstract: An FPD encapsulation apparatus at least comprises a chamber and a pressing mechanism. In this case, the chamber has an airtight space to provide a low-pressure environment, and the low-pressure environment is located inside the airtight space. The pressing mechanism is disposed within the chamber, and the pressing mechanism is operated in the low-pressure environment for pressing a second substrate to bind a first substrate and the second substrate. Furthermore, a method for encapsulating an FPD is disclosed. The method comprises providing a first substrate, forming an adhesive on the first substrate, providing a second substrate to align the first substrate and face to the adhesive, providing a low-pressure environment for the first and second substrates, and binding the first and second substrates to form the FPD.Type: ApplicationFiled: October 24, 2003Publication date: May 13, 2004Inventors: Tung-Sheng Cheng, Yi-Fan Su, Yen-Hua Lin

Patent number: 6732905Abstract: Fluxless soldering processes use pressure variations and vented cavities within large-area solder joints to reduce void volumes and improve the properties of the large-area solder joints. The vents can be sealed after soldering if closed cavities are desired. A cavity can also improve hermeticity of a solder joint by providing an additional solder fillet around the cavity in addition to the solder fillet around the perimeter of the solder joint.Type: GrantFiled: April 16, 2002Date of Patent: May 11, 2004Assignee: Agilent Technologies, Inc.Inventors: Giles Humpston, Yoshikatsu Ichimura, Nancy M. Mar, Daniel J. Miller, Michael J. Nystrom, Gary R. Trott

Patent number: 6719871Abstract: A method for bonding heat sinks to packaged electronic components comprises the steps of: (a) exposing to a plasma a surface of a molded polymer formed on a substrate; (b) allowing the plasma to at least partially convert silicon-containing residue on the surface to silica; and (c) bonding an article to the surface by applying an adherent between the article and the surface. Often, the silicon-containing residue is silicone oil, a mold release compound, which may prevent the formation of a bond when using conventional bonding methods and materials. The silica layer formed on the surface of the molded polymer assists in formation of a proper bond. The plasma may be an oxygen plasma and the adherent may be selected from either a heat cured silicone-based paste adhesive with a metal oxide filler or a heat cured porous polymer film impregnated with adhesive.Type: GrantFiled: January 9, 2001Date of Patent: April 13, 2004Assignee: International Business Machines CorporationInventors: Frank D. Egitto, Michael A. Gaynes, Ramesh R. Kodnani, Luis J. Matienzo, Mark V. Pierson

Patent number: 6706132Abstract: Methods for fabricating laminations to form structural elements of predetermined shapes (120, 220, 420, 520, 620) are provided. Laminations include parts (22, 24) fabricated from the tread portion (42) of discarded rubber tires. The parts are typically arranged in layers with various relationships therebetween. The parts are pressed to remove all voids therebetween causing dynamic tension which creates rigidity and then bonded with methods including vulcanization, chemical vulcanization, epoxy and adhesive.Type: GrantFiled: February 27, 2001Date of Patent: March 16, 2004Assignee: Tire Recycling Development CorporationInventor: Joseph H. Coffin

Patent number: 6698484Abstract: We reduce core crush in honeycomb sandwich structure by using a peripheral tiedown ply, generally in combination with a scrim-reinforced barrier film, between the composite laminate and the core along the panel chamfer to prevent slipping of the barrier film and outer laminates relative to the core during curing. We produce superior panels with lighter weights, improved mechanical properties, and more predictable structural performance.Type: GrantFiled: October 1, 1998Date of Patent: March 2, 2004Assignee: The Boeing CompanyInventors: Darrell H. Corbett, Stuart A. Smith

Publication number: 20040031561Abstract: An improved method of weldbonding utilizing inclusion bodies, placed directly between materials to be bonded or included in a weldbonding adhesive. The inclusion bodies maintain a gap between the materials to be welded which provides a gas releasing egress route to disperse the gas and gaseous byproducts produced during welding. This egress route substantially prevents the gases and gaseous byproducts from being expelled through the weld pool and the resultant degradation of the quality of the weld pool, particularly with coated materials, partial penetration welds, and such materials as 6000 series aluminum. The method further comprises an optional step of including a crack-reducing additive, applied either directly to the materials to be welded or included in the adhesive. A laser weldbonding embodiment may use a plurality of phased heat cycles to reduce weld imperfections, and enhance the effects of the adhesive and optional crack-reducing additive.Type: ApplicationFiled: August 13, 2002Publication date: February 19, 2004Inventors: Kevin J. Ely, Timothy M. Frech, George W. Ritter

Publication number: 20040020581Abstract: The method of this invention adheres a low emissivity radiant barrier material to an underlying lignocellulosic substrate within the primary manufacturing operation of the underlying lignocellulosic substrate. Thus, a radiant barrier covered substrate is formed by integrally joining the radiant barrier covering to a mat of lignocellulosic material during consolidation thereof with a first adhesive bonding material to form an underlying substrate. The integral joining operation can, for example, be accomplished by bonding the radiant barrier covering to a lignocellulosic mat in a product formation press. This is typically accomplished using a second adhesive bonding material for adhesion of the radiant barrier material to the lignocellulosic mat, and a first adhesive bonding material for consolidating the lignocellulosic mat to form a lignocellulosic substrate.Type: ApplicationFiled: May 28, 2003Publication date: February 5, 2004Inventors: Jay Tanzer, David C.

Publication number: 20030226637Abstract: Films are closely conformed to substrates by reducing the air pressure to a subatmospheric level in at least one airflow pathway that is present in the film or the substrate. The reduced air pressure enables the film to tightly contact the substrate in locations where protrusions or depressions on the substrate are present. The method is particularly useful for conforming film containing graphics to a variety of substrates such as the sides of semi-trailers or concrete block walls, even in instances where the semi-trailer sides include rivets and/or grooves and where the concrete block wall is relatively rough.Type: ApplicationFiled: June 11, 2002Publication date: December 11, 2003Inventors: John R.
