Patent number: 6263636Abstract: A floor, wall, roof, or ceiling of a building is made of specially adapted beams and overlying panels. The beams have a layer of foam material on their edges. The foam material can include a resiliently compressible material, a thermally insulating material, or a material which possesses both of these properties. The panels are positioned over the beams so that the foam material is sandwiched between the beams and the panels. When the panels are fastened to the beams, the resiliently compressible foam material partially compresses, thereby filling any gaps which may form between the beams and the panels. The resiliently compressible foam material thus prevents relative movement between the panel and the beams which would otherwise produce squeaks. When the foam material includes thermal insulating material, it forms a thermal barrier between panels and beams, especially metal beams, thereby eliminating various drawbacks of construction using metal beams.Type: GrantFiled: February 17, 1998Date of Patent: July 24, 2001Inventor: Charles Corston

Patent number: 6238504Abstract: The present invention relates to a method of applying adhesive to corrugating media to produce corrugated materials by foaming the adhesive with air prior to application to the flute tips of the corrugating media. The foamed adhesive requires less precise control of the applicator rollers, and remains in place on the flute tips, rather than migrating into the flute valleys. As a result, the same volume of adhesive can be used with decreased solids content, decreasing overall adhesive cost and increasing corrugator productivity. In addition, because of the more precise placement of the adhesive on the tips of the flutes, a stronger, higher quality board can be produced. The adhesive can be starch-based, and can be foamed by a variety of methods, such as in existing pin-rotor stator containing foaming machine used for foaming latices.Type: GrantFiled: July 22, 1998Date of Patent: May 29, 2001Inventors: Raymond C. Simmons, Jr., W. Lamar Brown

The body member and bottom panel member are oriented and joined to form a seal at an interface between a portion of inside surface of the body member and a portion of the upper surface of the bottom panel member. The printed matter is applied prior to foaming of the synthetic resin on the outer surface of the cup.Type: GrantFiled: March 6, 1998Date of Patent: October 31, 2000Assignee: Fort James CorporationInventors: Michael A. Schmelzer, Diana L. Penn, Mikel A. Ingram

Patent number: 6140381Abstract: This invention relates to a process for the production of a polyurethane backing and air frothed foam on a substrate comprising the steps of a) mixing a polyisocyanate and a polyol blend in the presence of a catalyst to form a reaction mixture, b) applying the reaction mixture to a substrate, and c) curing the reaction mixture to form a polyurethane backing an/or an air frothed foam on the substrate. Suitable catalyst compositions for the present invention include those corresponding to the formula: ##STR1## wherein: each R: independently represents a linear or branched C.sub.1 to C.sub.24 (preferably from 5 to 16 carbon atoms and most preferably from 8 to 12 carbon atoms) alkyl group, or a cyclic group containing from 4 to 24 carbon atoms (preferably from 5 to 16 carbon atoms and most preferably from 8 to 12 carbon atoms).Type: GrantFiled: June 7, 1999Date of Patent: October 31, 2000Assignee: Bayer CorporationInventors: James W. Rosthauser, Hartmut Nefzger, Robert L. Cline, Gerard C. Erhart

Patent number: 6132539Abstract: A method in which a polyolefin foam layer is laminated to a sealing film having at least a first layer of a polyolefin. During the lamination a second layer is located between the first layer and the foam layer; the second layer is extruded therebetween and pressure is immediately applied. The second layer and the first layer are polyolefins each based on the same monomer as the main monomer of the foam layer. The same lamination technique may be used to laminate a sealing film to the other side of the foam layer, optionally at the same time as the lamination of the sealing film to the first side of the foam layer. Alternatively, the lamination technique may be used on one side of the foam layer, and the other side of the foam layer may be sealed by means of a coextruded layer.Type: GrantFiled: November 24, 1997Date of Patent: October 17, 2000Assignee: Convenience Food SystemsInventors: Jacques Laurent, Michel Pittet

Patent number: 6132540Abstract: A method of fabricating a door and a door. A first step involves molding a first door skin. A second step involves molding a second door skin. One or both of the first door skin and the second door skin have molded in place rails. One or both of the first door skin and the second door skin have molded in place stiles. A third step involves integrally bonding the first door skin and the second door skin. This produces a door having a body with integrally formed skins, rails, and stiles. A lock latch area and hinge pockets can also be integrally molded into the door.Type: GrantFiled: December 7, 1998Date of Patent: October 17, 2000Assignee: Northern Delichte Ltd.Inventors: Douglas Victor Barber, Victor Joseph Mazier
