Abstract: The invention is a wall finishing system which is a sheet material designed to cover an entire wall, requiring minimal seams. The wall material has the characteristic of shrinking after application causing surface irregularities to pull out to a smooth plane. The sheet material can be applied to various substrates including finished or unfinished drywall, paneling, cement block, etc.

Abstract: A method is disclosed for sealing and bonding the seams and edges of resilient and other types of floors, whereby specially formulated hot-melt sealants/adhesives are applied in molten form at the flooring installation site using a heated gun equipped with a specially designed tip. The hot-melt sealant/adhesive flows into and completely fills the seam and bonds to the edges of the flooring producing a bead of material that extends above the surface of the flooring. The specially designed tip facilitates this process by guiding along easily in the groove of the seam or joint and directing the molten sealant/adhesive accurately into the seam. The tip allows the seam or joint width to be very narrow and enhances sealing and adhesion by imparting heat to the edges of the flooring material. Upon cooling, a spatula knife or other appropriate tool is used to skive off the excess bead of material leaving it flush with the flooring.

Abstract: A ceiling board has a depression formed in the four corners of the face surface of the ceiling board. When the horizontal flange of one cross runner overlies the horizontal flange of the main runner, the edge of the ceiling board will rest on the flange of the main runner because the overlying runner is accommodated in the corner depression.

Abstract: A duct lining insulation system for lining variable air volume boxes, air handling units, and ducts for heat ventilation and air conditioning has a sheet of a flexible, closed cell foam composition, said sheet having a face with a substantially smooth surface and having a coating of a pressure sensitive adhesive on a second face of the sheet, further providing that the pressure sensitive adhesive has a volatile content that is sufficiently low so that the adhesive gives off substantially no volatiles.

Abstract: The apparatus is a storage and transport rack for deformable rolled goods. One or more shelves each support a single layer of rolls. The shelves have an open input side for loading, a padded backstop opposite the input side, and unobstructed ends for unloading individual rolls with a ram pole lift truck. The upper surface of the shelves is tilted relative to the horizontal with the input side higher, so that the rolls move to the padded backstop, and a sloped ramp at the input side of the shelves starts the rolls down the shelf and assures that the rolls will not roll off the input side. For transport, the rolls are anchored by the use of straps tightened between "D" rings attached at the backstop side of the shelves and "D" rings on plugs inserted into the hollow cores of the rolls.

Abstract: The welding rod used to weld the surface covering has a laminate structure in which a print layer is disposed between a first thermoplastic layer and a second transparent thermoplastic layer. Preferably the welding rod is in the form of an elongated element having a half-round cross-sectional shape. The welding rod is used to join two pieces of thermoplastic sheeting, particularly flooring, together. If the welding rod has a pattern similar to the printed pattern of the sheeting the resulting surface covering looks seamless.

Abstract: A highly filled surface covering, preferably a floor covering and more preferably a floor tile, includes a resin layer which has about 80% to about 95% by weight of filler and a chlorine-free binder. The binder includes a mixture of a maleic anhydride grafted polyethylene and a substantially linear ethylene/octene copolymer. The ratio of maleic anhydride grafted polyethylene and ethylene/octene copolymer is from about 1:5 to about 1:15 by weight. The preferred formulation for the binder includes a solid tackifier selected from the group consisting of a hydrocarbon resin having an ester moiety and hydrogenated aromatic resin.

Abstract: A resin composition comprises an acrylated polyester, the polyester being the reaction product of an equivalent excess of 1,6-hexanediol and an aromatic polycarboxylic acid or anhydride, preferably trimellitic anhydride. In the preferred embodiment, the reaction product includes a highly ethoxylated triacrylate. Upon UV initiated polymerization or copolymerization, improved clear coatings for "no-wax" resilient floors are obtained. These coatings have better resistance to household and other stains than commercial urethane/acrylate floor coverings.

Abstract: This invention describes two products both with a plain, fine textured, nonperforated surface visual consisting of a fiberboard substrate with or without a laminated porous nonwoven scrim and then a finished painted surface. The finish painted surface decorates or finishes the board, but most important, must remain acoustically transparent to retain the sound absorption properties of the fiberboard prior to painting. The fiberboard substrate is made to be porous or modified with hole perforations to cause it to be a good sound absorber. If the fiberboard substrate is sufficiently porous without hole perforations, then the sprayable, high solids, porous paint can be directly applied. If hole perforations are used to improve the sound absorption properties of the board substrate, then a porous, nonwoven scrim is attached and painted using the same high solids porous paint.

Abstract: Using a combination of relatively coarse filler and latex binder, a very high solids coating (about 85% or higher) can be produced with a relatively low working viscosity. These very high solids coatings can be applied in thick single layers and oven cured without cracking. They maintain more than 80% of their original wet thickness. The resulting coating provides an extremely hard and durable surface, even on relatively soft mineral fiber board ceiling tiles or wall panels.

Abstract: A suspended ceiling system has a plurality of ceiling panels, ceiling runners, and a plurality of clips holding the ceiling panels to the ceiling runners. Each ceiling panel has two opposed surfaces and four sides with at least two sides having an extended edge each of which are substantially perpendicular to one of the opposed surfaces. Each extended edge has a protruding lip. The length of the protruding lip is limited so that the protruding lip does not extend for the entire length of the extended edge.

Abstract: Floor coverings include a wear layer made from a coat composition including a multifunctional polyurethane (meth)acrylate oligomer. The multifunctional polyurethane is made by reacting a polyisocyanate with a functionality equal or higher than 3, a polyester polyol, and a hydroxyalkyl(meth)acrylate with a number average molecular weight of about 344 to about 472. The coating composition preferably includes a reactive (meth)acrylate diluent and a photoinitiator.

Abstract: The apparatus is a transition member to cover the gap between ceilings at different levels which are also offset horizontally. A vertical section is supported at the edge of the lower ceiling and an attached angular section rises from the lower edge at a slope to reach and contact the upper ceiling. The general shape approximates a trough with one vertical and one sloped side. The lower edge of the vertical section and the upper edge of the angular section can include flanges and attached coupling channels which interlock with drywall adapters to facilitate attachment to drywall ceilings.

Abstract: This invention provides an aromatic or cycloaliphatic triazole-based chemical embossing inhibitor which is completely soluble in water and compatible with water-based printing inks for use in producing textured foamed plastic surfaces. The triazoles comprise a general class of mono- and multi-functional 1-N substituted aminomethyl derivatives which are rendered soluble in water by the presence of at least one polyethyleneoxide (PEO) oligomer chain, or polypropylene (PPO)-polyethyleneoxide copolymer oligomer chain or PPO/PEO/PPO triblock oligomer chain with a sufficiently high PEO/PPO ratio for water solubility. Preferably the triazole derivative has at least six polyethylene oxide monomer moieties per triazole moiety.

Abstract: Improved durability and sharper chemical embossing images are obtained in a thick foamed thermoplastic floor structure by the use of an unfoamed inner layer. The floor covering is formed on a release paper and includes an unfoamed thermoplastic base coat, lower foamed thermoplastic layer, an unfoamed thermoplastic inner layer, an upper foamed thermoplastic layer and a clear coat. The enhanced chemical embossing is achieved by printing an inhibitor containing ink on the inner layer and below the upper foamed layer. Multilevel embossing is obtained by embossing both foamed thermoplastic layers or applying a growth-controlling agent to both surfaces of one foamable thermoplastic layer. The preferred embodiment includes a pearl platelet containing layer above the upper foamed layer to give the illusion of deeper embossing. The preferred embodiment also includes a wear coat of the reaction product of an aminoplast, a urethane and a polyol.

Abstract: Vinyl heat welding rod for seam sealing vinyl resilient flooring, whether in sheet or tile form, are used to obtain a homogeneous, monolithic appearing surface. This rod is specifically made to duplicate the appearance of the flooring material. For a chip-image flooring structure, a sheet of multicolored chips having a similar, but different formulation from that of the flooring material is prepared and the sheet is cut into suitable strips, heat pressed in a rod mold, end adhered or further molded to form the desired length, and used as a vinyl heat welding rod for sealing seams in flooring. Thus, the chip pattern is evident in the seam area and does not appear different when compared to the adjacent surface.
