Abstract: The invention includes a tire having a pair of annular sidewalls each extending to a terminal end including a bottom surface for mounting onto a wheel. The tire further includes indicia arranged along each sidewall adjacent a bottom of each sidewall terminal end. The indicia extends radially outward from an initial position to extend from a top side of a rim flange of a tire wheel for indicating concentric mounting of the tire on a wheel. In particular embodiments, the tire is mounted on a rim of a wheel having rim flanges, each of the rim flanges extending along one of the tire sidewalls such that the indicia is adjacently arranged the rim flange along each sidewall such that the indicia extends radially outward from a top of the rim flange. Methods include using the indicia to determine whether the tire is concentrically mounted on the wheel.

Abstract: A tire component comprising a rubber composition having a highly unsaturated diene elastomer and a reinforcing filler with a first methylene acceptor selected from 3-hydroxydiphenylamine, 4-hydroxydiphenylamine or combinations thereof; a second methylene acceptor selected from a Novolac resin, diphenylolmethane, diphenylolethane diphenylolpropane, diphenylolbutare, a naphthol, a cresol or combinations thereof and a methylene donor.
Abstract: A tire comprising at least two working layers and at least one layer of circumferential reinforcing elements. The layer of circumferential reinforcing elements comprises at least a central part and two axially exterior parts, the elastic modulus of the rubber compound with which the circumferential reinforcing elements of the central part are coated being less than the modulus of the rubber compound with which the circumferential reinforcing elements of the axially exterior parts are coated.

Abstract: An electrically powered vehicle includes a fuel cell with a decomposition reactor for decomposing sodium chlorate (NaClO3). Reaction products produced by the decomposition reactor include oxygen and sodium chloride (NaCl). Gaseous hydrogen is stored onboard the vehicle, such as in a hydrogen tank at a low pressure, using metal hydrides. The hydrogen from the hydrogen tank and the oxygen produced by the decomposition reactor are consumed by the fuel cell in order to produce electricity. The vehicle further includes a storage tank for storing the NaCl produced by decomposition of the NaClO3.

Abstract: A process for manufacturing a continuous strip of self-sealing product having very low hardness, being very elastic and highly tacky, the strip being intended for feeding a converting machine, during which a thermoplastic protective film is deposited on the surface of the strip. The process includes a step during which a strip of self-sealing product P is extruded to a first cross section (S0) at the outlet of the extrusion die (10). The strip is surrounded over its entire perimeter using a thermoplastic film (20) by welding the film to itself, after having deposited the film (20) around the strip. The strip is calendered in order to bring it down to a second cross section (S2), smaller in area than the first cross section.

Abstract: A tire having a radial carcass reinforcement includes a crown reinforcement formed of at least two working crown layers of inextensible reinforcement elements, which are crossed from one ply to the other, forming with the circumferential direction angles of between 10° and 45°. The crown reinforcement is topped radially by a tread, which is joined to two beads by means of two sidewalls. The ratio of the thickness of the crown block at one shoulder end to the thickness of the crown block in the circumferential median plane is less than 1.20. The ratio of the axial width of the tread to the maximum axial width of the tire is strictly greater than or equal to 0.89.
Abstract: Metal cord (C-1) having two layers (Ci, Ce) of 3+N construction, rubberized in situ, comprising an inner layer (Ci) formed from three core wires (10) of diameter d1 wound together in a helix with a pitch p1 and an outer layer (Ce) of N wires (11) N varying from 6 to 12, of diameter d2, which are wound together in a helix with a pitch p2 around the inner layer (Ci), wherein said cord has the following characteristics (d1, d2, p1 and p2 are expressed in mm): 0.20<d1<0.50; 0.20<d2<0.50; p1/p2?1; 5<p1<30; 10<p2<30; the inner layer is sheathed with a diene rubber composition called a “filling rubber” (12) which, for any length of cord of at least 2 cm, is present in the central channel (13) formed by the three core wires and in each of the gaps lying between the three core wires (10) and the N wires (11) of the outer layer (Ce); and the content of filling rubber in the cord is between 5 and 30 mg per g of cord.

Abstract: Provided herein is an optical turbulence device configured for insertion between the target collimator and the sensor unit being tested, which simulates a turbulence effect. The turbulence device for imparting wavefront aberrations to a projected radiation beam includes an optical phase element for altering the optical phase of a radiation beam. The optical phase element includes a plurality of active areas disposed on a surface of the phase element. The plurality of active areas includes a plurality of variations for imparting wavefront aberrations to a radiation beam, thereby altering optical phase of the beam. The device further includes a driving mechanism coupled to the optical phase element for transitioning the optical phase element between a plurality of positions, thereby exposing a different active area of the optical phase element to the radiation beam. The optical phase element is configured to be positioned at an intermediate focal plane of an inverting a focal optical assembly.
