Abstract: A breaker reinforcing tape for belted pneumatic tires, a method of making such tape, and a method of constructing such tires therewith, are disclosed. The tape includes a generally sinusoidally crimped strip of uncured rubber and a plurality of similarly crimped parallel cords having their undulations following and nesting in the undulations of the crimped strip, the cords at successive apexes being secured to successive apexes of the strip. A second uncured rubber strip in a flat condition is secured to alternate ones of the apexes of the undulations of the array of cords and the crimped strip at one face of the latter. At least one frangible element is interposed in a fixed and substantially flat condition between the crimped and flat strips for releasably reinforcing and stabilizing the flat strip against inadvertent expansion that would prematurely reduce the amplitude and frequency of the undulations of the crimped strip and its associated cords.

Abstract: Blends of ethylene-propylene-ethylidene norbornene-type of EPDM rubber having a high ethylene content, polyolefin resin (e.g. polypropylene), dodecachloro-octahydro-dimethanodibenzocyclooctane and antimony oxide are flame retardant and have the desirable properties of a thermoplastic elastomer, especially good tensile and elongation retained over a wide range of rubber/resin ratios.

Abstract: Fungi, bacteria and viruses are controlled, especially on plants, by application of chemicals of the formula: ##STR1## such as 2,3-dihydro-5-phenyl-1,4-dithiin 1,1,4,4-tetroxide, 2-ethyl-5,6-dihydro-3-methyl-1,4-dithiin 1,1,4,4-tetroxide and 2,3-dihydro-5-methyl-2-phenyl-1,4-dithiin 1,1,4,4-tetroxide.

Abstract: A method and apparatus for determining the conicity of a tire wherein, while the tire is being corrected for radial force variation by grinding as it revolves in a first direction, the lateral thrust force of the lateral force variation is determined and stored. The tire is revolved in a second direction and the lateral thrust force is determined. The conicity of the tire is calculated by use of the post grinding lateral thrust force values and then is compared to a predetermined maximum allowable conicity. The tire is graded accordingly. Associated circuity and apparatus are disclosed.

Abstract: A golf ball having improved flight characteristics having a spherical surface with 252 depressions therein. 240 of the depressions are in the shape of inverted pyramids with hexagonal bases and 12 of the depressions are in the shape of inverted pyramids with pentagonal bases. The ball has two poles and an equator, and the pentgonal bases serve as the two poles and as the vertices of similar equilateral spherical triangles into which the surface of the ball may be divided.

Abstract: Organotin sulfinates are useful for controlling insects and acarids. Certain of these organotin sulfinates are novel compounds.

Abstract: Catalytic hydrogenation of o-nitrophenylazohydroxyaryls in an alkaline medium yields hydroxyarylbenzotriazoles; under mild conditions an N-oxide is formed. E.g., 6-tert-butyl-2-(5'-chloro-2'-nitrophenylazo)-p-cresol is hydrogenated to 5-chloro-2-(3'-tert-butyl-2'-hydroxy-5'-methylphenyl)benzotriazole, using platinum sulfide catalyst in the presence of sodium hydroxide: ##STR1## IN THIS CASE A in the starting chemical is 5-chloro, n is 1, Ar is a phenyl nucleus, m is 2, one B is 6-tertbutyl and the other B is 4-methyl; in the product x is zero. Chemicals useful for various purposes, including the stabilization of polymeric materials (e.g., polypropylene, polyvinyl chloride) against light, may be made by the process.

Abstract: Novel enamines, obtained from aldehydes or ketones, may be incorporated into a white-wall tire stock to greatly enhance the ozone resistance of the stock while greatly reducing discoloration or staining of the stock. The aldehydes and ketones utilized are those having at least one alpha hydrogen linked to the carbonyl group.

Abstract: An adjuvant for an elastomeric composition is made by mixing methacrylic acid with a suspension of zinc oxide in a liquid medium (such as water or alcohol) in the proportions required to form basic zinc methacrylate. Removal of the liquid from the reaction product and blending of the finely divided reaction product with an elastomer such as cis-polybutadiene yields a composition which, when cured (for example with an organic peroxide), is hard yet resilient. Molding of the composition in the form of a golf ball produces a durable solid golf ball which has in large measure the play characteristics of a wound golf ball, and substantially retains such characteristics after extended play.

Abstract: A method and apparatus for separating and winding pre-treated yarn, for example, tire cord, the method comprising two stages. In a first stage, a coated and heat-set fabric, constituted of longitudinally running warp cords and laterally running picks interlaced with the warp cords, is subdivided into a plurality of elongate tapes, each tape having a lesser number of warp cords than the fabric and picks of reduced linear extent. The tapes are then wound into respective packages. In the second stage, the tapes are unwound and divided each into a plurality of independent warp cords free from the picks. The warp cords are then wound into respective packages.

Abstract: A rubber, radially expansible ring in a tire building drum is provided for gripping the bead of a tire carcass. The ring is radially expansible in a continuous, circumferential channel of the drum. The ring has an outer surface suitably shaped for holding the bead of the tire carcass, and a pair of continuous, circumferential pressure sealing flaps extending inwardly from both sides of the ring. The flaps are adapted for sealing engagement with adjacent side members of the circumferential channel, so that the ring may be radially expanded without the use of an inflatable bladder. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.

Abstract: A fire retardant system comprising a compound having within its structure the 1,2,3,4,9,9-hexahalo-1,4-dihydro-1,4-methanonaphthalene-5,8-dione or 1,2,3,4,9,9-hexahalo-1,4-dihydro-1,4-methanonaphthalene-5,8-dioxy nucleus or a compound which is capable of being converted to the 1,2,3,4,9,9-hexahalo-1,4-dihydro-1,4-methanonaphthalene-5,8-dione nucleus and requires no metal oxide addition to exert its function.

Abstract: A tow plate is provided which is suitable for use with a floatable oil boom. The tow plate comprises a vertically planar central plate, a pair of skis facing the front of the tow plate and attached to the top portion of the central plate, a buoyant material secured to the upper surfaces of the pair of skis whereby the tow plate is floatable in water, and a pair of planar fins attached perpendicular to the bottom portion of the central plate.

Abstract: Belted pneumatic tires, each belt ply of which includes both metallic and non-metallic cords interspersed with one another and of which the non-metallic cords are made of a material having a relatively high modulus generally of the same order of magnitude as that of the metal, are disclosed. In a preferred arrangement, each belt ply has steel wire cords arranged in a 1:1 alternating sequence with glass fiber cords. The sequence can be varied by having successive metal wire cords separated by two or more non-metallic cords, or by having successive pairs or greater numbers of metal cords separated by one, two or more non-metallic cords, and so forth. The use in tires of belts of such cords, eliminates tire wear and failure due to buckling and birdcaging of belts formed solely from non-metallic tire cords.

Abstract: A pivotable sensor shoe in a tire grinding machine for tracking the tread surface of a pneumatic tire. The sensor shoe comprises a pivot point and a curved tracking surface. The tracking surface includes a minimum length long enough to provide point contact with the tread surface at opposite ends of the tracking surface length. The tracking surface has an arc whose radius is such that at least two point contact between the sensor tracking surface and the tire surface may be effected. This abstract is not to be taken as a complete position or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.
