Abstract: A moisture-permeable acoustic lamina which is usable as a wall covering has a foraminous woven fabric layer adhered to a fabric backing by a discontinuous thermoplastic polymer layer. The woven fabric preferably has an embossed undulate outer surface to enhance the acoustic properties of the lamina and to impart an aesthetic textural appearance. The individual yarns of the woven fabric are preferably substantially uniformly coated with a polyvinyl chloride plastisol to impart stain and wear-resistance, inhibit the growth of molds, fungi, bacteria and the like, and to enhance the appearance of the exposed face of the lamina. The moisture-permeable lamina structure allows wall covering paste, used to adhere the lamina to a wall, to dry at an acceptable rate, yet does not allow paste to bleed through the foraminous woven fabric layer.

Abstract: A method and an apparatus for coating rigid objects made of wood or a wood fiber material with a plastic film. The plastic film is heated by a heating element emitting radiation of sufficient wavelength, whereby the temperature of the plastic film remains sufficiently low. After heating, the plastic film is lowered on the object to be coated a surface of which has been treated with a heat activatable adhesive. When the film touches the surface of the object, the adhesive is activated and adheres the film to the object. The adhesion is further enhanced by the sucking of air from between the object and the film.

Abstract: A method producing a thermobonding interlining comprises the steps of depositing a non-woven layer of intermingled fibers or filaments presented in a general direction on a conveyor of wire netting, directing toward said conveyor weft yarns made of textured continuous filaments that are kept in a stretched condition and parallel with one another; depositing the weft yarns in a zone where the non-woven layer is being deposited such that the weft yarns are oriented crosswise to the general direction of and covered by the non-woven layer. Afterwards, such superposed weft yarns and non-woven layer assembly is subject to the high pressure jets of water from injectors disposed above the conveyor so that the weft yarns and the fibers or filaments of the non-woven layer are intermingled to obtain a base material of interlining. Then, the base material of interlining is dried in a thermal treatment. The dots of thermofusible polymer are deposited one face of the base material of interlining.

Abstract: A process for the application of a releasable adhesive layer to the floor abutting surface of a ceremonial roll that can be easily unrolled and used to cover a walkway to provide a ceremonial cover therefor is described. This process employs elevated pressures and temperatures within a given time frame to laminated this adhesive layer to the floor abutting surface of the roll. This adhesive is then pressed onto the floor of the walkway itself before the roll is rolled down the aisle or walkway to be used. The adhesive will hold to the floor during the unrolling but can easily be removed by pulling up at an angle of greater than 30.degree. from the floor without being removed from the floor abutting surface of the roll. The adhesive will resist from 10 to 300 pounds of pull at angles less than this 30.degree.. The ceremonial roll may be made from a host of materials but a non-woven, fabric like materials made from long, natural and synthetic fibers are preferred.

Abstract: A first object, which comprises organic material, is bonded to a second object by a method whereby both objects are provided with complementary optically smooth surfaces, subsequent to which these surfaces are brought into substantial contact with one another, consequent upon which spontaneous atomic bonds are formed between atoms of the two objects. The strength of the atomic bonds thus formed can be increased by subsequently heating the region of contact of the two surfaces.

Abstract: A flexible liner is formed from a resilient material and includes a back side surface having a number of ribs that project outwardly a distance away from the liner. The ribs each have an enlarged profile configured to provide a strong mechanical lock with an intermediate adhesion layer or carrier that is applied to a surface portion of the underlying substrate needing surfacing or rehabilitation. The liner is installed to surface or rehabilitate a structure by applying a thickness of the carrier to the wall section of the underlying substrate, positioning a back side surface of the liner adjacent the carrier, pressing the liner against the carrier so that the ribs are inserted and completely covered by the carrier, and forming a mechanical lock between the ribs and the carrier. The carrier is formed from a resinous material that has good adhesion properties and that displays good chemical and/or corrosion resistance when cured.

Abstract: A lightweight fiberglass recreational vehicle cabin for carriage on a pickup truck is fabricated in two laterally distinct halves which are subsequently bonded together to form a unitary structure. Each cabin half is fabricated inside of a female mold which is supported on a horizontal pivot axis so that during the fabrication process the mold may be rotated to whatever orientation best facilitates each fabrication step. Each cabin half is fabricated by applying a layer of fiberglass to the inside of the female mold, applying a layer of polyurethane foam over the fiberglass, and placing preformed fiberglass interior shell segments inside the mold to contact the polyurethane foam, thereby forming a sandwich-type wall structure. The two molds are then brought together to place the cabin halves in registry, and they are bonded together by applying joining materials to the inside of the seam.

Abstract: A method of forming a lightweight, contoured, structurally stable, self-supporting laminate comprises laying down, in succession, a finish lamina, a first heat activated adhesive, a first thermoformable scrim lamina, a second heat activated adhesive, a high density polymeric foam lamina, a third heat activated adhesive, and a second thermoformable scrim lamina thereby forming an unbonded laminate. This unbonded laminate is then uniformly heated in an oven to a temperature sufficient to make the adhesives bondable thereby forming a heated, substantially unbonded laminate. This heated, substantially unbonded laminate is then quickly transferred to a contoured die press and permanently bonded and formed, under pressure. The laminate is permanently bonded utilizing the residual heat in the laminate to form a contoured, structurally stable, self-supporting, impact resistant laminate.

Abstract: A method of selectively applying adhesive to the tops of ribs on a ribbed-substrate. The method includes the steps of applying a layer of adhesive to a flexible, polyimide carrier; drying the adhesive layer; rolling the ribbed substrate against the carrier so that the adhesive layer contacts the rib tops but does not contact the substrate in the regions between the ribs; and separating the adhesive from the carrier, thereby depositing the adhesive on the rib tops. The ribs typically have heights and widths from about 1 to 10 .mu.m, and are separated by distances of 1 to 10 times those dimensions.
