Abstract: A flat cast structural member, particularly a cast metal part or a cast plastic part wherein the surface of the structural member is covered by a thin metal sheet or a plastic layer. An adhesive or coupling layer is provided between the thin metal sheet or plastic layer, whereby under the influence of heat, the adhesive or coupling layer absorbs any surface unevenness or irregularities on the structural member.

Abstract: A composite structural reinforcement has a keyed reinforcement member in which a thermally expandable resin strip is mechanically retained. The mechanical interlock permits the resin to be secured to the member without heat or an adhesive.

Abstract: A reverse molded fiberboard panel; a wainscot kit comprising a plurality of differently sized reverse molded panels, and a planar finishing or spacer panel, adapted to completely cover any size wall between a wall base board and a wall chair rail; and a method of reverse molding a loose cellulosic mat, in a single pressing step, to provide one or more relatively high density, raised panels without requiring preliminary pressing, or other pre-shaping step, such as scalping. The reverse-molded panels are molded in a conventional, multi-opening fiberboard press, in a single pressing step process, while achieving excellent transfer of mold detail (embossing fidelity) without visually noticeable fiber fracture.

Abstract: A flame retardant composite sheathing including a core layer, having a plurality of superposed layers of a water-resistant paperboard adhered together by layers of an adhesive positioned intermediate and contacting adjacent said layers of water-resistant paperboard, a first layer of a polyolefin adhered to a major surface of the core layer, a metal foil adhered to the first layer of polyolefin, a second layer of a polyolefin adhered to the metal foil, and a layer of water resistant liner board adhered to the second layer of polyolefin.

Abstract: A plastic panel assembly for use in a vehicle is provided including a sheet metal frame constructed and arranged to be coupled to a vehicle and a plastic panel mounted to the sheet metal frame. The plastic panel includes a plurality of pin members extending from a surface thereof and the frame includes a plurality of openings therethrough such that one pin member is disposed through an associated opening. Fastening structure is constructed and arranged with respect to the pin members to retain the plastic panel to the frame so that the panel is prevented from moving relative to the frame in a direction of extension of the pin members while the panel is permitted to move relative to the frame in a direction transverse to the direction of extension of the pin members, upon thermal expansion of the panel.

Abstract: A reinforced panel structure made by impregnating resin in a knitted fabric and allowing the resin to cure. The fabric comprises first and second spaced layers (1,2) which are interlinked by an intermediate pile layer (3) comprising two sets of ribs (4,5). The ribs (4) comprise monofilament yarns having a relatively high stiffness sufficient to provide a restoring force during impregnation of the fabric with resin. The ribs (5) are made from multifilament yarns, spun yarns or composite yarns, selected for desired properties of the finished fabric and/or for their wetting properties during impregnation.

Abstract: A building element (1) comprising an outer sheath and an inner core, the sheath being formed of a material having a greater tensile strength than compressive strength and the core having a greater compressive strength than tensile strength; wherein the outer sheath is longitudinally extending and has a first face (7) and a second face (8) which are spaced apart, first (9) and second (21) edges and a first and second end; wherein the first face (7) and the second face (8) are joined at the first (9) and second (21) edges to form the outer sheath as a continuous body, and wherein the first edge (9) and the second edge (21) are so shaped that the first edge (9) of one such building element (1) is adapted to locate in the second edge (21) of another such building element (1).
