Abstract: A continuous, two-ply thermoplastic film material, sealed in a manner that forms superimposed panels into individual, inflatable bags that are repeated and separable, individually or in groups of bags, forms a continuous packaging material. The material can be cut or torn from preformed rolls to a desired size to over-wrap a product with an air cushion. Valves are sealed into the material at repeated locations to allow air insertion at any location or to allow a primary air chamber to feed any length of pre-sealed bag material that can be sectioned and filled with air at the same time. The invention also allows wrapping of a product first, without air, and insertion of the wrapped product into a carton or box with provision for inflating the wrapping to conform tightly to the product, inside the carton or box. The wrapping material can be recycled either as a reusable, inflated wrapper or made of biodegradable plastic materials to minimize environmental damage.

Abstract: Borazine oligomers in liquid form are produced and used to create composites of fibers bonded to boron nitride as a matrix and also to coat or increase the density of various fiber composites.

Abstract: An air bag apparatus in which the appearance of the interface between the portion covering the air bag and portions surrounding it can be improved, the number of components can be reduced, and the assembly process can be shortened. A cover unit covers an air bag, which inflates on a predetermined occasion, consists of a cover which-opens with the inflation of the air bag, and a body for holding the cover. The cover unit is an integrally molded product in which a skin is formed on a substrate, and includes, at the location connecting the periphery of the cover with the body, a breakaway portion along which the cover is separable from the body when the air bag inflates, and a hinge portion for maintaining the connection of the body and the cover. In the breakaway portion, the substrate has a fragile portion, and the skin is separated into two parts at the position of the fragile portion. In the hinge portion, the substrate and skin are continuously formed and extend from the body to the cover.

Abstract: The present invention is directed to an aqueous polyisocyanate dispersion which has an isocyanate content of at least 0.5% by weight, based on the weight of the polyisocyanate, and is prepared bya) dispersing in water a polyisocyanate which has an isocyanate content of at least 12% by weight and is rendered hydrophilic by reaction with a compound containing a lateral or terminal nonionic hydrophilic group andb) chain extending the dispersed polyisocyanate with a primary or secondary monoamine containing at least one hydroxyl group in an amount sufficient to provide an equivalent ratio of amino groups to isocyanate groups of 0.6:1.0 to 0.95:1.0.

Abstract: A covering made of heat-resistant fibers for tools in contact with glass heated to beyond their softening point, in particular, for bending/tempering tools which are themselves heated in excess of the softening points of the glass sheets, is composed partially of metal fibers and partially of ceramic fibers.

Abstract: A coating is adapted to be applied to a fabric in order to enhance the thermal characteristics thereof. The coating includes integral and leak-resistant microcapsules filled with phase change material or plastic crystals that have specific thermal properties at predetermined temperatures.

Abstract: A polytetrafluoroethylene (PTFE) porous film is formed from a PTFE resin molding powder obtained by suspension polymerization. The film has a porosity of 40 to 80% and a removal ratio of uniform particles having a diameter of 0.2 .mu.m less than 99%, or has a porosity of 40 to 80% and a bubble point of not less than 3 kg/cm.sup.2. This PTFE porous film is obtained by a process of compression-molding a PTFE resin molding powder to prepare a preform, sintering the preform at a temperature not lower than the melting point of the unsintered PTFE, processing the preform into films, then laminating at least two of the obtained films, fusing the films to unite them, and subjecting the obtained film to uniaxial or biaxial stretching at a temperature not higher than a melting point of the sintered PTFE. If desired, the finally obtained film may be subjected to heat setting. In the PTFE porous film of the invention, pores are nearly round and the diameters of the pores are almost uniform.

Abstract: A void-free, latex rubber cushion layer is interposed between the blanket cylinder and the base layer of a compressible printing blanket in an offset printing press. The latex cushion layer has a thickness of from 8 to 12 mils, and has a spring modulus which is substantially less than the spring modulus of the compressible layer in the printing blanket. The latex cushion layer will compress slightly, about 1 mil, in response to preloading at typical preload impression pressure. This means that a good quality print may be obtained at a substantially reduced impression pressure level, since it is not necessary to preload the blanket. During a printing operation, the latex cushion layer is under preload compression and applies a back pressure force which assures a quality imprint. The compressible layer of the blanket, which has a greater spring constant, is not compressed at the typical printing pressure setting.
