Weatherproofing backer for window and door installation
Hohmann, Jr. of MiTek Holdings, Inc., Delaware, developed a weatherproofing backer for installing windows and doors consisting of a foam layer and an adhesive layer.  The adhesive is pressure-activated and is self-sealing about attaching hardware.  The foam is self-setting and, in use, molds to the flange of the window unit.  When installed, the foam layer is compressed between the inner window frame and rough opening and between the window flange and the wall surface adjacent the rough opening.  The weatherproofing backer is designed to extend beyond the flange of the window unit and thereby receive the weatherproofing membrane thereover.  The weatherproofing backer, then acts as a sealed bridge between the membrane and the window unit precluding entry of air and water.  Both the foam and the adhesive have fire retardants in the formulation. A tape form with a self-skinned foam layer and a sheet form, with polymeric covering web are provided. (RDC 11/9/2012)

Carpet waste composite
Murdock, Mancosh and  Przybylinski of Material Innovations LLC, Rhode Island, developed a composite from carpet waste and a binding agent and may also include wood fiber or chips and/or other additives.  A method of manufacturing a composite material includes shredding carpet waste, coating the carpet waste with a binding agent, and subjecting the shredded, coated carpet waste to elevated heat and pressure. As an additional step, the composite material may be actively cooled to prevent deformation of the material.  (RDC 10/9/2012)

Copolymer synthesis process
Lorenz et al of Construction Research & Technology GmbH, Denmark, developed a non-ionic copolymer having a hydrolysable monomer residue and a polyether macromonomer residue in a semicontinuous mode in a polymerization reactor associated with a metering device, including introducing polyether macromonomer and water into the reactor, wherein hydrolysable monomer which is added thereto forms a polymerization reaction mixture; introducing hydrolysable monomer into the metering device; adding hydrolysable monomer into the reactor from the metering device; passing a free radical polymerization initiator into the reactor before and/or during the addition of the hydrolysable monomer, the hydrolysable monomer and the polyether macromonomer reacting by free radical polymerization to form the non-ionic copolymer; and, subjecting the reaction mixture to polymerization while an addition rate of the hydrolysable monomer and/or at least a component of the polymerization initiator is varied stepwise or continuously. No monomer is introduced to incorporate ionic cement binding sites into the non-ionic copolymer. (RDC 8/30/2012)

Thermoplastic single ply protective covering
Naipawer, III and Ruffine of the Building Materials Investment Corporation, Delaware, developed a single ply protective roof covering including (a) providing a single ply thermoplastic roofing membrane, and (b) coating the single ply thermoplastic roofing membrane on its bottom surface with a 1-50 mil layer of a pressure sensitive adhesive mixture consisting essentially of polyisobutylene and at least one polymer comprising conjugated diene monomers.  The method of installing includes (a) providing a single ply thermoplastic roofing membrane, (b) cutting the single ply thermoplastic roofing membrane to a selected size, (c) positioning the single ply thermoplastic roofing membrane on a portion of a roof, and (d) bonding the membrane to the roof. (RDC 8/16/2012)

Molding profile and molding profile assembly
Insa of Faus Group Inc., Spain, developed a molding profile assembly to form and molding profile assemblies (or moldings) used to transition from a first flooring surface to a second flooring surface, where the first and second flooring surfaces may be at the same or different height. (RDC 8/14/2012)

Resin anchor with a compressible envelope containing curable products, at least one of which is sacheted
Bucquet, Gauthier and Caille of the Societe de Prospection et d'Inventions Techiques Spit, France, developed a resin anchor based on an apertured tubular envelope designed to be compressed by a traction element including on the inside, a resin and a hardener that are intended to be mixed together and to cure under the action of the compression of the envelope (1), in order to fasten the anchor, at least one of the two components being sacheted, the mix formed from the two components being expelled out of the envelope via its apertures, during its compression. The traction element may be a screw that cooperates with the end element of the bushing CD forming a nut. The anchor is fastened both mechanically and chemically, for either solid material or hollow material. (RDC 6/4/2012)

Use of polymeric microparticles in building material mixtures
Einfeldt et al of Construction Research & Technology and Evonik Rohm, Germany, used hollow polymeric 0.1 to 1 micron diameter microparticles in hydraulically setting building material mixtures where 10 to 100% by volume is filled with water.  This makes concrete resistant to freezing and thawing.  In addition, the compressive strength of the correspondingly hardened concrete is substantially improved.  The microparticles consist of  a polymer acid core (A) and a nonionic polymer shell (B).  The unsaturated carboxylic acid (derivative) can be acrylic acid, methacrylic acid, maleic acid, maleic anhydride, fumaric acid, itaconic acid or crotonic acid.  (RDC 5/23/2012)

Acoustic ceiling tiles made with paper processing waste
Baig of USG Interiors, Illinois, produced making acoustic tiles form paper processing wastes. Perlite; inorganic material selected from the group consisting of calcium sulfate, calcium carbonate, and clay; a binder selected from the group consisting of starch, a combination of starch and cellulosic fibers, latex, kraft paper gel and mixtures thereof; optionally mineral wool; optionally gypsum; and cellulosic fiber, wherein at least a portion of the cellulosic fiber are from pulp and paper processing waste. An aqueous slurry is placed onto a moving foraminous wire to form a cake. The cake  is dewatered to form a base mat and dried to produce a base mat.  (RDC 4/25/2012).
