Abstract: A reinforced, anti-fatigue foam floor tile module which comprises first and second resilient foam layers, and in between the foam layers, at a distance of about 55% to 65% of the thickness from the back surface of the mat, is a dimensionally-stabilizing, fibrous, particularly glass, scrim sheet material. The foam floor tile module has a foam density ranging from about 20 to 40 pounds per cubic foot, comprises a substantially closed cell foam and has an embossed face surface having a decorative or non-slip pattern thereon with the foam layer densified under the embossed areas.

Abstract: A resilient, abrasion-resistant foraminous surface covering material, such as a floor mat, which mat comprises a layer composed of a plurality of relatively stiff, resilient fibers, each fiber intersect with one another. The fiber is coated with a high density, polymeric foam material. When surface of the coated fibrous material having a plurality of irregular islands of polymers with lower surface form a generally planar gripping surface, and the other top surface, characterized by a discontinuous, irregular surface, the coated, fibrous material having a relatively large, open area therethrough to permit the drainage of liquids through the surface coating covering material.

Abstract: A flame-resistant carpet tile having low smoke values and improved flame resistance which carpet tile comprises a primary backing having a fibrous face and a fibrous back, a barrier layer adjacent to fibrous back to an acrylic polymer heavily loaded with a metallic flame-retardant salt filler material which acrylic polymer is compatible with a vinyl chloride polymer layer and a relatively thick vinyl chloride polymer backing layer adhering to the barrier layer.The method of preparing a flame-resistant carpet tile which comprises pre-coating the back of a carpet with an acrylic polymer latex containing a metallic salt flame-retardant filler material, coating the latex material with a PVC layer, thereafter laying the latex PVC coated carpet into the top surface of a liquid PVC backing layer, heating the laid-in carpet to fuse the PVC layers, cooling the carpet and cutting the carpet into carpet tile.

Abstract: A system for loading a workpiece onto a carriage for traverse relative to a pattern-producing instrumentality comprising a bottom plate positioned on the carriage, a top plate, a picker movable relative to the carriage from a loading position remote from the carriage to a clamping position adjacent the carriage, electromagnets on the picker for releasably holding the top plate thereon for movement therewith on the one hand to lift the top plate from the bottom plate to said loading position and on the other hand to lower the top plate to said clamping position, positioning pins on the picker for positioning and holding the workpiece on the top plate in a predetermined position thereon during movement of the top plate from the loading position to and from the clamping position, said electromagnet being operative to release the top plate at the clamping position, holes in the top plate and pins on the bottom plate interengageable when the top and bottom plates are brought into engagement at the clamping positio

Abstract: A flame-resistant vinyl-foam gasket material particularly for use as an insulating draft shield in electrical outlets and switch boxes, which gasket material comprises a layer of a flexible, vinyl-foam sheet material suitable for use as a gasket material, and containing a dimensionally stable, glass-fiber tissue sheet material integrally positioned and secured within the foam layer, the gasket material meeting the flame test standards of CSA C.22.2 No. 18 4.1.4.

Abstract: An imitation-leather sheet laminate material is prepared employing an acidic, heat-coagulated, cross-linkable, elastomeric, latex polymer, wherein the acidic latex polymer is coated onto a top, resin, skin layer and a fibrous base sheet is placed on the wet foam layer, which method comprises: shock-heating the wet foam layer to coagulate and cross-link the polymer therein into a fine, open-cell, tough, foam layer and to remove rapidly water from the coagulated foam layer.

Abstract: A diagonal bias-stretching device and a method of enhancing surface grain of imitation-leather material with such device, which device comprises a reciprocating roller moving between lateral positions on either side of a line of advance of an imitation-leather material, to provide for alternating diagonal stretching and relaxing of the material as it moves under tension in the line of advance.

Abstract: An imitation-leather sheet laminate material is prepared employing an acidic, heat-coagulated, carboxylated, elastomeric latex polymer, wherein the acidic latex polymer is coated onto a top resin skin layer and a fibrous base sheet is placed on the wet foam layer, which method comprises: shock-heating the wet foam layer to coagulate the carboxylated polymer therein into a fine, open-cell, tough foam layer and to remove rapidly water from the coagulated foam layer.

Abstract: The method of lasting footwear with liquid latex comprising depositing the latex in a wet, liquid, low-viscosity, nonadhesive form on the surface of the feed roll, of a pair of cooperating feed rolls of a progressive-type lasting machine, which normally has contact with the inner side of the lasting margin of the upper material at a place apart from the lasting margin, while the deposited latex is traveling from the place of deposit on the surface of the feed roll having contact with the inner side of the lasting margin to the place of contact with the lasting margin, spreading it uniformly thereon and rendering it partially coagulated and adhesive, transferring the partially coagulated adhesive latex to the lasting margin at the place of contact and, as the latex-coated surface of the lasting margin is released, pressing it against the latex-receptive surface of the insole, and apparatus for carrying out the method.

Abstract: The method of wet lasting the lasting margin of a shoe upper to the marginal edge of the bottom structure which comprises, progressively lasting the lasting margin of an upper to the margin of a bottom structure which has along its margin at least, a dry receptive adhesive coating and while so lasting the margin applying a liquid coating of latex in a controlled amount to the inner side of the lasting margin just before it is laid down.

Abstract: The method of appliqueing sheet material, in particular, bonding a synthetic resin such as polyvinyl chloride to one or more portions of a woven fabric, comprising supporting the synthetic resin applique in compressive engagement with the sheet material in a high frequency field at a temperature such as to cause fusing and bonding of the applique to the sheet material and while fusing the synthetic resin of the applique conducting vapors generated within the sheet material by said high frequency heating away from the sheet material to allow the use of a level of power to cause the synthetic resin to penetrate into the sheet material and to prevent condensation of the vapors on the platens of the high frequency press employed to effect bonding.
