Patent number: 9482627Abstract: 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.Type: GrantFiled: July 28, 2014Date of Patent: November 1, 2016Assignees: Michelin Recherche et Technique S.A., Compagne Generale des Etablissements MichelinInventors: Reza Zoughi, Mohammad Tayeb Ghasr

Publication number: 20140228510Abstract: 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.Type: ApplicationFiled: October 16, 2012Publication date: August 14, 2014Applicants: COMPAGNE GENERALE DES ETABLISSEMENTS MICHELIN, MICHELIN RECHERCHE ET TECHNIQUE, S.A.Inventors: Rachid Matmour, Nicolas Seeboth

Publication number: 20130299058Abstract: 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.Type: ApplicationFiled: November 14, 2011Publication date: November 14, 2013Applicants: Michelin Recherche et Technique S.A., Compagne Generale des Etablissements MichelinInventors: Pascal Pirotte, Christophe Egerszegi
