Abstract: Outer plies of cellulosic tissue and an intermediate, Isotropic, reinforcing textile length fiber web are attached together by a pattern of adhesive lines with the fibers of the web embedded in the adhesive lines, to provide a tissue fiber laminate nonwoven fabric which is flexible and conformable with adequate strength particularly in the cross direction so as to be suitable for use as a textile substitute.

Abstract: An aqueous alkaline dispersion of a rubbery vinyl pyridine copolymer, trimethylol phenol, and a resorcinol compound, in certain amounts, is useful in forming an adhesive for bonding glass fiber reinforcing elements or cords to rubber compounds or stocks. After dipping the glass fiber cord in the one-step adhesive dip, the coated cord is heated to dry it and heat cure or heat set the adhesive on the cord. Thereafter, the adhesive containing glass fiber cord is combined or laminated (calendered) with a curable rubber compound and the resulting assembly is cured to form a composite in which the glass fiber cord is bonded to the rubber by means of said adhesive.

Abstract: Thermoplastic synthetic polymer fibers having powder of metal attached to the surface of the fibers are subjected to a treatment for increasing the oxidation number of said metal from zero to a plus value, that is, oxidation in a broad sense. The resulting conductive synthetic fibers support a layer of a compound of the metal, i.e. an oxidized product of the metal in a broad sense, firmly and undetchably thereon, and have as low an electric resistivity as 10.sup.5 .OMEGA./cm or less. The conductive fibers can be blended to ordinary synthetic fibers to improve their antistatic property, or can be substituted for expensive metal fibers. The thermoplastic synthetic polymer fibers are sheath-core fibers wherein the sheath has a lower melting point than the core.

Abstract: A data bearing card having a magnetizable, transparent, colorless coating thereon is disclosed. The coating can comprise a transparent, colorless plastic matrix containing a dispersed particulate crystalline phase. The dispersed phase is prepared by mixing 20-60% of a rare earth compound containing a colorless ferromagnetic ion such as gadolinium with 0.1-5% of titanium dioxide or zirconium oxide, 0.05-2.5% of an inorganic fluoride salt and the balance up to 100% of a glass forming matrix such as inorganic borates. The mixture is heated above its melting point to form a homogeneous melt and subsequently crystallized. The resulting crystalline product can be ground to any desired particle size for dispersion in the transparent plastic matrix.In general, the coating composition is useful in all applications where magnetic coatings are presently used.

Abstract: A method of improving the dimensional and thermal stability of a fibrous web containing substrate is disclosed. A uniformly or randomly spun or bonded fabric or textile support is impregnated with a curable polymer resin, e.g., an epoxy-polyester resin. The impregnated resin is then fully cured whereupon a polymer resin coat is applied thereto. The coat is maintained in a partial cure state whereby a laminate comprising an internal woven or bonded fabric skeleton impregnated with a fully cured polymer resin and coated with a layer of a partially cured polymer resin is obtained.

Abstract: An impervious cover structure is produced by laying a polyolefin fabric fused on one side only, fused side against the surface to be covered, and the unfused side is coated with a mixture containing asphalt and asbestos fibers.

Abstract: A web of indeterminate length carrying thermally transferable material, usually referred to as hot stamp tape, is structured to provide an improved simulated wood grain pattern on a substrate after transfer to the substrate of transferable portions of the tape. The web or tape may be provided in sheet form. The structure comprises "ticks" or discrete linearly oriented spots of material having low specular reflectivity coated on a matte carrier sheet, as by printing, and a layer coated thereon to provide the top layer of the transferred material, which replicates the surface of the carrier sheet and the coated "ticks" or spots.

Abstract: A method for producing a multi-layer web, and the web produced thereby, are disclosed. The nonwoven web consists of two half-thickness portions laminated to each other. A first half-thickness portion is characterized by a given overall concentration of long and short fibers and has one face enriched in long fibers above the overall concentration and the other face enriched in short fibers above the overall concentration. The concentrations of long and short fibers decrease substantially uniformly from the enriched faces to form a transition region within the half-thickness portion. The second half-thickness portion is bonded to the short fiber-enriched face of the first half-thickness portion and has an outer face (opposite the bonded face) of substantial structural integrity as compared to the short length fiber-enriched face of the first half-thickness portion.

Abstract: Transparent sheet having peripheral adhesive area designed to form enclosure enabling viewing of material upon adhesive engagement of the sheet with a substrate wherein a specifically defined section of the peripheral adhesive area is serially renewable enabling repeated engagement and disengagement of the defined adhesive section and substrate and access to the pocket formed and material contained therein.

Abstract: An improved polyethylene terephthalate tire yarn is prepared by applying to the yarn a finish composition comprising a polyalkylene glycol compound having the formulaR--(O--R.sub.1 --O--R.sub.2).sub.n --OHin which R.sub.1 and R.sub.2 are the same or different lower alkylene units such as ethylene, propylene and so forth up to 5 carbon atoms, R is an alkyl group containing 1 to 8 carbon atoms, and n has a value to produce a molecular weight of at least about 300; and about 5 to 35 parts per 100 parts, by weight, of said polyalkylene glycol compound of a triol compound having the formula: ##EQU1## WHEREIN R and R' are independently at each occurrence hydrogen, methyl or ethyl and r, s, and t are integers from 1 to about 20. This method of finishing the tire yarn results in an improved adhesion of the fiber to rubber.

The composite filament consists essentially of (a) a block copolymer, as the first component, having a melting point of not lower than 170.degree.C and consisting essentially of 35-80 wt. % of a polyester, as the hard segment, predominantly containing a tetramethylene terephthalate unit and 20-65 wt. % of a long-chain glycol having a molecular weight of 500 to 5,000 as the soft segment, and (b) a polyester, as the second component, predominantly containing a tetramethylene terephthalate unit. The composite filament produces crimps superior particularly in percent of crimp and percent of crimp retentivity when drawn and relaxed.

Abstract: Pressure polished transparent unfilled polycarbonate sheet substantially free of ripples, wiggles, extrusion die lines, and stresses and having a light transmittance greater than, a percentage haze lower than and a distortion lower than the as extruded sheet so that the polished sheet can be mechanically or thermoformed into such articles as airplane windshields, canopies, protective headgears and see-through enclosures. The sheet is made by polishing it between mirror finish plates using a sequence of preheating the as extruded sheet to the heat distortion temperature at zero or minimal pressure, heating to higher temperatures while rapidly increasing the pressure so as to transfer the mirror finish from the plates to the sheet surfaces, and cooling the sheet while decreasing the pressure to fix the mirror finish in the sheet surfaces as the sheet contracts and solidifies.

Abstract: Pen nibs are made by extruding rods from fused thermoplastic material, with a cavity in the rod of star-shaped cross-sectional configuration. The extruded rod is then cooled and mechanically drawn to reduce its diameter about 50%, which closes the inner ends of the arms of the star and brings them together at the center of the rod, while leaving the outer ends of the arms relatively large. The resulting product is then sharpened at both ends for use as a pen nib.
