Abstract: A closed cell phenolic-resin foam material comprising phenolic-resin foam forming reactants, a blowing agent, and a surfactant which is the capped reaction product of an alkoxylated amine and a copolymerizable mixture of dialkyl maleate with N-vinyl-2-pyrrolidone or N-vinyl caprolactam.

Abstract: This invention relates to an improved weather strip and balance assembly for nonremovable windows in which the weather strip is made of a compressable, high impact material with ridges thereon to mount the sash. The ridges also mount and enclose the balance springs and pulley blocks with the sash cord coupled thereto for counter-balancing the weight of the sash. The sash cord is directed out from behind the weather strip through an opening therein to connect to the sash through an anchor. The length of the sash cord at the connection of the sash is adjustable to adjust the tension of the balance system applied to the sash. The assembly is readily assembled in said jambs of a window frame by securing the same thereto, such as by screws. The assembly is manufactured, shipped and stored without tension thereon to eliminate warpage and displacement of parts.

Abstract: A process for producing a closed cell phenolic-resin foam material comprising a phenolic-resin polymer and surfactant which is branched, non-ionic, with a hydroxyl value less than 50 achieved by capping excess hydroxyl groups; the material, and a structural laminate employing the material. The material has a thermal conductivity which is low initially and remains low for a long period of time.

Abstract: A novel and highly efficient insulating wall structure for a building comprises a generally closed wall with a top venting structure only. The wall structure generally comprises two substantially moisture and air impervious barriers spaced from each other by intervening framing members, a bottom substantially moisture-and-air impervious closure sealing the bottom of said barriers and a venting structure locating only at the top of said wall to release water vapor from the interior of said wall.

Abstract: A structural laminate comprises at least one planar facing sheet with a rigid foam attached to one surface of the facing sheet. The rigid foam is characterized in that the major recurring chemical linkage therein is the isocyanurate moiety. Distributed substantially evenly throughout the foam is a mat of long straight glass fibers arranged in layers substantially parallel to the facing sheet. The process for producing this structural laminate comprises the steps of contacting a thin, substantially incompressible yet expansible mat of long straight glass fibers with a foam-forming mixture of an organic polyisocyanate and a diol, positioning a facing sheet on each face of the mat, and passing the facing sheets having the mat and the foam-forming mixture there between through the nip of two rotating rolls.

Abstract: A fan housing assembly for an exhaust fan is provided with an orifice pan which can be securely but removably snapped in place to close an open face of the fan housing and provide a means of supporting a ventilating grille.

Abstract: Phenolic polymers which can be produced by reacting ortho-cresol with other phenolic materials, such as phenol, are described. Phenolic compositions comprising these phenolic polymers mixed with other phenolic materials, cellular materials produced from these phenolic polymers having low friability, and related processes and products are also described.

Abstract: An apparatus for making a laminated board having a foam plastic core between adhered sheets has limiting means for inhibiting escape of the foam plastic core outwardly of the sheets.

Abstract: A structural laminate comprises at least one planar facing sheet with a rigid foam attached to one surface of the facing sheet. The rigid foam may be any polymeric material which is capable of being foamed. Distributed substantially evenly throughout the foam is a mat of long straight glass fibers arranged in layers substantially parallel to the facing sheet. The process for producing this structural laminate comprises the steps of contacting a thin, substantially incompressible yet expansible mat of long straight glass fibers with a foam-forming mixture on each face of the mat, and passing the facing sheets having the mat and the foam-forming mixture there between through the nip of two rotating rolls.

Abstract: An apparatus cuts a saturated sheet into wide and narrow sheets, coats the top and bottom surfaces of the wider sheet with bituminous coating adhesive, shifts the location of the narrower sheet to a position so that the centerlines of each sheet are in alignment, coats the back of the narrower sheet with bituminous adhesive, and laminates the aligned sheets with the narrower sheet adhered to the bottom surface of the wider sheet. The sheets are then cooled, cut into predetermined shapes and packaged. The shaped laminated shingle is also claimed.

Abstract: Certain phenolic cellular materials of low thermal conductivity can be produced by having in the cells of the cellular material a synergistic mixture of trichlorofluoromethane and 1,1,2-trichloro-1,2,2-trifluoro-ethane in a molar ratio of 1:20 to 20:1.

Abstract: A unique clip which can be formed by the extrusion of plastic material and cut in strips can be used in a wide variety of positions to support suspension members for ceiling panels.

Abstract: Polyisocyanurate foams are produced by admixing from separate sources, an organic polyisocyanate, a diol, and a catalytic composition which comprises an alkali metal carboxylate and polyoxyethylene polyol.
