Abstract: Strong, lightweight structural shapes or structures adapted for anistropic load bearing useful as structural beams or stiffeners for other structures, e.g., aircraft and which prevent or have improved resistance to forces tending to peel apart the structures, i.e., incipient peel. The shapes are fabricated from plicated laminates of strips or sheets of resinous, filament reinforced, composite materials having high strength and low weight. Fabrication of the shapes is carried out in such manner that upon curing of the resin the resultant stiffener shapes are capable of distributing loading forces so as to reduce localization of stresses.

Abstract: Improved placement apparatus comprises a compliant backer sheet, e.g., formed of foamed polyvinyl chloride, and a clear transparent overlay sheet, e.g., of vinyl, disposed over the backer and secured on three sides thereto, as by thermowelding, to fuse the contiguous backer and overlay plastic materials.A graphics sheet desired by a consumer, e.g., a wallpaper or fabric segment, is inserted between the backer and overlay, and enclosed by securing a flap-like member affixed to the overlay to the backer sheet. A double sided acrylic copolymer adhesive strip is advantageously utilized to secure the flap and backer sheet.

Abstract: Walled structures are prepared from foam-in-place components such as those used to prepare rigid polyurethane foams wherein successive strips of foam are deposited and hardened within a three-sided enclosure having a generally H-shaped configuration. A foraminous scrim such as glass fiber mesh forms part of the vertical legs of the H and foam is disposed below the cross piece of the H to bond to adjacent scrim facing sheets and scrim of a previously disclosed strip. The foam is significantly reinforced, joined to the previously deposited structure and foaming components are isolated from depositing apparatus.

Abstract: Compositions useful as sealing primers for elastomeric coatings comprise (A) the reaction product of a polyurethane polyol and a polycarboxylic acid or acid anhydride, and (B) an aminoplast resin. When used as primers, the compositions of the instant invention increase the durability, gloss retention and adhesion of elastomeric coatings. Such primers are particularly useful on resilient and rubbery substrates such as EPDM rubber, foam rubber, polyurethane foam and vinyl foam.

Abstract: Cured coatings having a high degree of extensibility and other desirable properties are obtained from compositions comprising a hydroxyl-containing, urethane reaction product containing a polyester component and an amine-aldehyde resin. Preferred compositions contain a polymeric polyol of low glass transition temperature. These compositions are storage-stable in one package, and the cured coatings are adherent, durable and highly extensible. These coatings are particularly useful on resilient and rubbery substrates, such as form rubber, polyurethane foam and vinyl foam, and on soft metal surfaces such as mild steel and aluminum.

Abstract: A diaper fastener comprising an elongated strip of tape having an adhesive coated surface and a web adhesively secured to that surface in the longitudinally central portion of the strip, the exposed surface of the web having a limited affinity for the adhesive. The adhesive coated surface in one end portion of the strip is in contact with that exposed web surface. An opening is provided through the web whereby regions of adhesive in the end and center portions of the strip of tape which are aligned with the opening in the web are in contact with each other for releasably securing the end portion.

Abstract: Improved forming method permits a flat laminate panel comprising a thin, deep vacuum formed thermoplastic face surface member bonded to a rigid backing member to be bent sharply so as to form the sides and front of a cabinet, for example, in one integral piece. The bends are accommodated by removing material from the back of the panel so as to form V-grooves whose included angles are equal to the angle of bends desired. The grooves extend through the entire thickness of the backing member and a portion of the plastic layer. A small bead of hot melt adhesive placed in the groove serves to soften the plastic so it can be bent without cracking. The panel sections adjacent the V-grooves are then brought into contact and immediately and permanently bonded together by the adhesive, thus eliminating the need for additional bracing while the adhesive sets.

Abstract: Laminates are prepared from rigid panels or sheets (e.g. gypsum board or plywood) and resin-saturated paper by a unidirectional pressure process which simultaneously bonds the paper to one of the broad flat sides of the panel or sheet and to one or more of the adjacent thin sides of the panel or sheet which intersect the broad side. The resulting laminates are useful in the construction of walls and furniture.

Abstract: A diaper fastener comprising a strip of tape having an adhesive mass disposed over a surface thereof and a unit removably secured to the strip in a longitudinally central portion of the strip. The unit provides an exposed surface (facing away from the strip surface) having a limited affinity for the adhesive. An end portion of the strip is folded over and in contact with the unit exposed surface. The unit itself comprises outer and inner layers of web each of which has a surface which has limited affinity for the adhesive and which faces away from the other layer. The outer layer includes tabs which project longitudinally beyond the ends of the inner layer and which are secured to the strip surface.

Abstract: An assembly for imprinting indicia upon a tape in the form of a small strip of cloth, plastic, etc., to be applied by heat sensitive adhesive to an item to be identified by the indicia on the label. The assembly includes a sheet of carbon paper, or the like, for transfer of the marking material to the label by localized pressure, and a sheet of material having a pressure sensitive adhesive on one side. The assembly is so constructed that the tape is in facing engagement with the transfer layer of the carbon paper and the pressure sensitive adhesive is disposed for engagement with an underlying support surface to hold the assembly firmly in position while the markings are being applied.
