Abstract: A warp resistant tile and method for preparation thereof in which a primary facing layer is secured to a tile backing layer which comprises a laminate having(A) a characterizing layer of predetermined weight, bulk, and strength, this layer and being complementary to the primary facing, and to(B) a thin flexible base layer.

Abstract: Disclosed are hot melt compositions having good resistance to flow at temperatures up to 100.degree. C. The compositions are homogenous blends, which consist essentially of (1) an ethylene--mono-unsaturated ester copolymer having a melt index from 2 to about 20, or an ethylene terpolymer having a melt index of from about 6 to about 20; (2) a heat resistant polymer having a crystalline melting point greater than 109.degree. C.; (3) a tackifier resin having a Ring and Ball (R&B) softening point of from about 85.degree. C. to about 110.degree. C.; and (4) a hydrocarbon wax. When the tackifier resin has a R&B softening point of 100.degree. C. to about 110.degree. C., a naphthenic oil must also be added. The compositions may also contain a finely divided inorganic filler when used as an adhesive to produce pile fabrics or for backcoating the primary backing of a tufted carpet. The compositions are useful in the manufacture of carpets.

Abstract: A method and device for monitoring and evaluating structural stability of a multicomponent laminate body by use of a plurality of oriented sensor fingers, each of which comprises a supporting structure and sensing means secured thereto, the sensing means being capable of anchoring or securing, at one end, to one or more preselected components or subgroup of the laminate body with transversely arranged probing means endwise secured to a laterally movable linking member connected to a recording means for translating relative lateral movements between said components or subgroups under preset conditions into a mechanical or electronic record.

Abstract: Disclosed is a precoat resin dispersion having a solids content from about 63% to about 69% comprising (1) at least one resin having a Ring and Ball softening point from about 60.degree. C. to about 100.degree. C. in an aqueous dispersion having a solids content from about 53% to about 58%; (2) at least one water-soluble polymer; (3) at least one cationic resin; and (4) water. The precoat resin dispersion is useful in the manufacture of tufted carpets, especially carpets manufactured with carboxylated latices as a backcoat.

Abstract: Disclosed is a pre-coat composition consisting essentially of (1) a low density polyethylene having a melt index of from about 70 to about 425; (2) a nitrogen-containing silane cross-linking compound, (3) a resin having a Ring and Ball softening point from about 50.degree. C. to about 115.degree. C.; (4) a hydrocarbon wax; and (5) optionally naphthenic oil. The composition is useful in the manufacture of tufted carpets.
