Abstract: A laminated hose is present which is suitable for a fuel conducting hose or other hose, or diaphragm, used for example in an automotive vehicle, which structure is required to have excellent heat resistance and gasoline permeation resistance while maintaining suitable properties of bonding and flexibility. The hose is constituted by an inner veneer layer of THV, a terpolymer of tetrafluoroethylene, hexafluoropropylene and vinylidene fluoride, as a permeation barrier layer. This inner layer is reinforced by an elastomeric tie layer, a reinforcing layer and an elastomeric cover.

Abstract: Electric cables with sector-shaped conductors, for maximizing duct capacity, are made by a process in which the shaped metallic conductor is first preformed into a helical twisted form ("pre-spiralled"), next covered with insulation of EPR, polyethylene or other suitable insulation material to form a core, third subjected to ionizing radiation to crosslink the insulation, and fourth laid up with other like cores to form a cable. All the steps are well known yet the potential to apply radiation crosslinking to this type of cable--in which other crosslinking techniques are wholly impracticable--has not hitherto been appreciated.

Abstract: Bonding of expanded polymeric parts together to produce lost foam molds suitable for casting metallic details is accomplished by applying a non-aqueous, adhesive-free coating comprising a polar, highly dielectric component contained in a liquid vehicle to the interfacing surface of at least one of the parts to be joined. The interfacing surfaces of the parts to be joined are held in contact while the assembly is irradiated with high frequency electromagnetic energy. This energy enables the coating to dielectrically heat the mated expanded polymeric parts until a bond is effected by melting the polymeric parts and inducing expansion of the parts into one another.

Abstract: An improved method is described for the fusing, joining or seaming of cellulosic materials. The method utilizes a solution of selected organometallic compounds or metal oxides to rapidly crosslink opposing, overlapping cellulosic surfaces to provide secure seams. Enhanced seam strength is achieved by a subsequent moisture treatment. The tubular cellulosic casings are well-suited for the manufacture of sausages and sausage-like products. The seams according to this invention have exceptionally high shear strength and wet strength.

Abstract: A method of adhering a film to a panel of a cathode-ray tube, comprised of adhering a light transmitting type functional film to the surface of a panel glass while interposing an ultraviolet ray-curable resin layer therebetween, then bringing the film into tight contact with the panel glass from the inside of one end portion toward that one end portion, then bringing the film into tight contact with the panel glass toward the other end. Further, when bringing the film into tight contact with the panel, by heating by irradiating the front surface of the panel by ultraviolet rays, the resin protruding from the periphery of the film is cured, the work process is shortened, and the handling is facilitated.

Abstract: Composite non-woven fabrics are disclosed. The fabrics comprise at least a first ply that is an antibacterial fibrous web, and a second ply comprising a web of non-woven non-antibacterial fibers serving as a "base structure" providing strength and dimensional stability to the fabric. Each ply adheres strongly to adjacent plies of the fabric by inter-entanglement of the fibers in the respective layers with each other, which defines an intensity gradient of antibacterial property across the thickness dimension of the fabric. The fabrics can be made sufficiently soft and mild for skin contact, and have many uses such as in clothing, medical fabrics, sheets, and the like. The fabrics have the same or a lesser amount of antibacterial fibers than prior-art non-woven antibacterial fabrics without adversely affecting strength, dimensional stability, or antibacterial efficacy.

The reinforcing panels include multiple synthethic fibers that are arranged parallel to one another and aligned with the longitudinal direction of the panel, and accordingly the wood structure. The fibers are maintained in position by a resin encasement.

Abstract: A thin film layered member having high heat dissipation efficiency is composed of at least two diamond layers and at least one interlayer. The diamond layers and the interlayer ape alternately laminated and the diamond layers form outer surfaces of the thin film layered member. When this member is applied to a heatsink or the like, thermal stress to an element mounted thereon can be reduced because of a laminated structure comprising an interlayer having a high coefficient of thermal expansion and diamond layers having a low coefficient of thermal expansion. Further, the interlayer includes a carbide forming metal, which reacts with carbon atoms constituting a diamond in a laminating process and to form a carbide at an interface between the interlayer and the diamond layer, thereby realizing strong bonding therebetween.
