Abstract: A steel-belted radial ply tire construction characterized by improved uniformity and resistance to ply separation, and a method of manufacturing such tires in non-segmented molds, are disclosed. In the finished tire, a cap band having at least one layer of rubberized tire cords of synthetic filamentary textile material is disposed in direct surrounding relation to the radially outermost belt ply of bias-angled steel cords, the cap band having a width equal to or greater than the width of the belt, with the cords in the cap band being disposed parallel to one another and to the median equatorial plane of the tire, i.e., at an essentially 0.degree. bias angle. The cords in the cap band are prestressed, due to their having been stretched about 1 to 5% in the manufacturing operation during the final expansion of the tire into the mold contours under high internal pressure, so as to exert a stability and uniformity-enhancing compressive stress on the underlying belt.

Abstract: The production, by either a batch process or a continuous process, of vehicle seat trim pads or like articles of cured polymer no-gel latex foam and having convex or crowned surfaces free of congealed polymer skin, is disclosed. In the process, a backing fabric is first laid on a pervious supporting surface. A no-gel latex foam is then deposited on the fabric, and an open-bottom open-top grid of a height not greater than that of the deposited mass of latex foam is placed into the latter, excess latex foam above the top plane of the grid being scraped off to impart to each pocket or island of foam a smooth and level top surface. The entire assembly is then subjected to dry heat to effect both a rapid dehydration and a curing of the latex foam. During the initial stage of this operation, the no-gel latex foam expands somewhat so that the top surface of each island thereof becomes crowned without having to be disposed in contact with a mold surface of appropriate contours.

Abstract: A method for determining the preferred direction of rotation of a vehicle tire including determining the direction of rotation of the tire in which the lateral structural force acting on the tire is greater. After this determination the tire is marked in a manner indicating the direction of rotation in which the lateral structural force is greater. In this way the tire may be mounted on a vehicle so that the conventionally forward direction of rotation of the tire is in the direction of greater lateral structural force so that the effect of the forces acting on the tire which tend to alter its direction of travel are minimized.

Abstract: The single-stage building of 0.degree. belted pneumatic tires completely in flat band form on standard building drums, is disclosed. The feasibility of the process rests on the provision of the substantially inextensible metallic or non-metallic belt cords in the form of longitudinally extensible high "soft stretch" tapes. In a preferred version of the invention, the tape is composed of a plurality of cords each having formed therein a multiplicity of undulations which in any given straight length of the tape are substantially planar, the cords being disposed in side by side relation so that the planes of the undulations of each cord are generally parallel to the planes of the undulations of each adjacent cord, and the cords together with a relatively weak and frangible but only minimally undulated stabilizing yarn for the tape being secured to each other and held in their undulating state by a relative weak, chain stitch knitted, frangible stitching yarn or thread.

Abstract: Polymers are flame-retarded by novel combinations of additives comprising:A. a specified compound of iron, cobalt, nickel, tin or antimony,B. an alkali metal chloride, bromide or iodide, andC. an organic acid or inorganic acid salt.Alternatively, additive (c) may be an integral part of the polymer in whole or in part.

Abstract: Method and apparatus for coating a fabric with elastomeric stock, wherein improved impregnation of the interstices of the fabric is achieved, the method comprising concomitantly feeding both elastomeric stock and a fabric in pressurized contact with one another between mutually confronting stationary and movable surfaces. The mutually confronting surfaces converge toward one another and cooperatively define a pressure chamber terminating in a restriction orifice. The movable surface is driven in a direction of feed of both the stock and fabric to frictionally carry and wedge both into and through the pressure chamber, thereby causing the interstices of the fabric to be increasingly impregnated by the stock.

Abstract: Cementitious structures characterized by improved durability and weather resistance are obtained by: Incorporating alkyl and alkenyl succinic acids, their anhydrides, acid esters, acid amides, halogenated compounds and salts, into cementitious mixtures prior to setting; applying said succinic compounds onto concrete subsequent to setting; or by a combination of the forgoing steps; said alkyl and alkenyl substituents containing from 8 to 40 carbon atoms.

Abstract: Solution halogenation of EPDM (rubbery terpolymer of ethylene, an alpha mono-olefin, and a nonconjugated diene) in the presence of an epoxy compound such as epoxidized soybean oil with or without a poly(alkylene ether) glycol yields a halogenated EPDM of excellent viscosity stability and limited gel content.

Abstract: A method for cooling a tire during a post-inflation treatment utilizing aspirator jets for discharging air internally of the tire and for entraining the inflation air of the tire to cause turbulent air flow against the internal surface of the tire and against tire-supporting means which is water-cooled to remove heat from the internal air of the tire. This invention results in tires which are at least as uniform, and generally more uniform, than externally jet air-cooled tires.

Abstract: Apparatus for transversely adjusting a longitudinally moving strip of tire breaker building fabric is disclosed. In one embodiment, for adjusting vertically moving fabric, the apparatus comprises a frame including first and second pluralities of cylindrical rollers, the first and second pluralities of rollers being spaced apart to allow the fabric to pass therebetween, first and second transversely spaced rails mounted on the frame for transverse movement, first and second pluralities of cylindrical rollers supported by the respective rails contacting the respective side edges of the strip for transverse movement thereof, a rotatable shaft connected to the first and second rails by first and second link arms for simultaneously and equally moving the first and second rails transversely, and a counterweight connected to the shaft for rotating the shaft in a first direction to urge the rails toward one another and into contact with the side edges of the strip.

Abstract: Fabric is coated with a cellular blend of polyvinyl chloride resin and butadiene-acrylonitrile rubber, the said rubber component being vulcanized; the coating is buffed to expose the cells and thereby produce an artificial suede finish. The presence of the cured butadiene-acrylonitrile rubber in the composition eliminates the undesirable "glint" or shine that would otherwise be present, and gives a desirable flat finish. If an additional noncellular layer of the blend of polyvinyl chloride resin and butadiene-acrylonitrile rubber is interposed between the base fabric and the cellular surface layer, the abrasion resistance of the laminate is enhanced.

Abstract: A method and apparatus for molding rubber to an article, e.g. a two-color rubber sole onto a lasted upper of an article of footwear, are disclosed. Unvulcanized rubber of one color is placed into a mold cavity bounded by the article, openable peripheral side ring means, and a movable mold member, e.g. a sole plate, located opposite the article. The movable mold member is provided with a peripheral outwardly extending lip for forming, in the rubber flash escaping around the periphery of the movable mold member, a peripherally extending weakened region. A peripherally extending groove is also provided in the movable mold member adjacent the lip to the side of the latter facing away from the article, for forming the flash rubber escaping past the lip into a bead. In the method, a first rubber to be molded is introduced into the cavity and the movable mold member is then advanced toward the article until the first rubber is spread against the article.

Abstract: An electronic, undamped oscillator driven by a periodic input signal (forcing function) having a frequency equal to the natural frequency of the oscillator develops an output sinusoidal signal having a rate of growth (amplitude increase) proportional to the amplitude of the first harmonic component of the input signal. When the input signal is a force variation signal and the oscillator is tuned to the rotational frequency of a tire mounted on the force variation machine, the rate of growth of the output signal of the oscillator is proportional to the amplitude of the force variation signal. A peak follower detects the amplitude of the increments between successive peaks of the oscillator output signal. A meter indicates the amplitude of the successive peaks of the oscillator output signal, thereby indicating the amplitude of the first harmonic component of the force variation signal.
