  • Patent number: 9482627
    Abstract: A method of inspection of a tire was developed using microwave imaging comprising the steps of selecting a plurality of regions from within a tire to be imaged; determining the dielectric properties of the tire components in each of the selected regions in a plurality of frequency bands; selecting a specific location on a tire to be imaged; providing a scanning platform for microwave imaging of the tire; imaging the selected location on a tire using microwave imaging at a plurality of microwave scanning frequencies and at a selected microwave polarization to obtain images of the internal state of the sample; and filtering the images to remove the effects of curvature of the selected location of the tire.

  • Patent number: 8960253
    Abstract: A technique for improving the durability of the beads of a radial tire for a heavy vehicle of the civil engineering type, by reducing the rate of spread of cracks initiated at the turned-back end of carcass reinforcement and the spread through the coating, edge-binding and filler polymer materials.

  • Publication number: 20140228510
    Abstract: A process for the synthesis of a diene copolymer comprising at least two blocks, at least one of the blocks being composed of a diene elastomer, characterized in that it comprises a stage of 1,3-dipolar reaction of two polymers defined as being: a) a diene elastomer bearing an alkyne functional group at one or each of its chain ends, and b) a polymer bearing at least one azide functional group. This process of synthesis can be adjusted, whatever the nature of the monomers necessary to form each of the blocks of the copolymer. Each block can be synthesized with an appropriate chemistry, independently of the other block.

  • Publication number: 20130299058
    Abstract: A tire intended to be mounted on a drop-center rim with a flange height G and a radius of curvature R1, comprising a first and a second bead, each comprising at least one annular reinforcing structure having a radially innermost point, the radial distance between the radially innermost point and the mounting rim being denoted by A; a carcass reinforcement anchored in the two beads by being turned back around the annular reinforcing structure so as to form, within each bead, a main strand and a turned-back strand, in which the first bead has a thickness EB1 and the second bead has a thickness EB2, the thicknesses EB1 and EB2 defined as the distance separating (i) the point on the main strand that is at a distance R from said point, where R=G+R1/2?A, and (ii) the point on the exterior surface of the bead that is at this same distance R from said point, and in which the absolute value of the difference between the thicknesses EB1 and EB2 is greater than or equal to 1 mm.

  • Patent number: 8527134
    Abstract: A method of identifying a position of a wheel of a vehicle includes: providing, in at least one wheel of the vehicle, a device with at least one magnetic sensor with a maximum sensitivity axis; starting up the vehicle; measuring at terminals of each magnetic sensor a signal representative of magnetic flux time variations during rotation of the wheel; determining a characteristic quantity of the signal; comparing the characteristic quantity to a given threshold; and determining, according to a comparison result, a front or rear location of the wheel.
