Abstract: Method and apparatus for producing a bed covering or the like comprised of a first thermoplastic web, a pair of fibrous mats of substantial loft, said web and mats being bonded together in accordance with a quilted pattern utilizing a thermoelectric bonding technique. The bonding layer, which is preferably polyurethane or a derivative thereof, forms an excellent bond with both the web and the fibrous mats. The fibrous mats provide excellent moisture absorbency and are breathable since the fibrous mats are bonded to the web only at the limited areas defined by the pattern. The first web provides an excellent waterproof barrier, while the mat provides an array of puffed-up regions each delineated by the bonding pattern to yield and aesthetically appealing cover which may be used with either fibrous web exposed.

Abstract: An adhesive of certain elastomeric block copolymers and tackifying materials can be hot-melt coated onto a flexible backing to provide an adhesive tape, two pieces of which can bond to each other to have excellent resistance to shear forces but can be easily peeled apart, even after prolonged periods of time. The adhesive can be low-tack or tack-free. When the novel adhesive is tacky, it can bind sheets into a note pad from which individual sheets can be removed, temporarily adhered to paper and other substrates, and later cleanly removed, even after prolonged contact.

Means providing an exposed layer of pressure sensitive adhesive along each of the opposite edges of the barrier layer are provided for adhering the barrier layer to structural members on opposite sides of a joint therebetween.

Abstract: A passive insulating system can provide highly effective protection in the presence of transient high temperatures. The system comprises, for example, a porous body forming a multiplicity of fine cells with a material having low thermal conductivity, a thermally absorptive liquid, providing an endothermic reaction in the presence of a catalyst, and a finely divided catalyst for the reaction uniformly distributed in the porous body. In preferred systems, the thermally absorptive liquid is para-hydrogen, the catalyst is granulated ferric oxide, and the liquid para-hydrogen changes to gaseous para-hydrogen, and from para-hydrogen to ortho-hydrogen in the presence of the ferric oxide catalyst, absorbing heat by its heat of vaporization and endothermic catalytic reaction and reducing heat transfer through the porous body.

Abstract: Breathable barrier fabrics are made by sizing a substrate, made of bonded fibers forming void spaces therein, with a film-forming material that fills the voids of the substrate to form a solid film between the fibers. The resulting non-porous breathable material provides a high strength fabric which is permeable to water vapor, such as body moisture, but impermeable to air and aqueous liquids. The non-porous breathable barrier fabric acts as a barrier against wind, dust or other airborne contaminants, e.g. bacteria, viruses, pesticides, etc., as well as against aqueous liquids such as blood. Alternatively, porous barrier fabrics can be made by incorporating air into the film-forming filler material to obtain greater comfort at lowered barrier qualities. The barrier fabrics of the invention are suitable for industrial, hospital and other protective covering uses.
