20110057350 | Method and Device for Making a Reinforcement by Winding a Tape on Itself - A device intended for creating a reinforcing strip formed by flattening a tube (t) comprising a first means for dispensing a tape (b) comprising an interleaf (D on one of its faces, at a given linear speed, and a second means comprising two rolls intended to flatten the said tube (t), in which device the said first and second means are able to be set in rotation relative to one another about an axis of rotation (XX′) parallel to the direction (p) in which the tape (b) progresses through the device, so that when the device is operating, the tape (b) is wound in a spiral on itself in contiguous turns to form a tube (t) the axis of which corresponds substantially to the axis (XX′) of rotation of the first means with respect to the second means, characterized in that it comprises a means ( | 03-10-2011 |
20110015303 | Rubber Composition in Particular for the Manufacture of Tires - A rubber composition, in particular intended for the manufacture of tires, based on at least a predominant elastomer, chosen from the group consisting of butyl rubbers, essentially unsaturated diene elastomers, essentially saturated diene elastomers and the mixtures of these elastomers, and a reinforcing filler, characterized in that the composition also comprises at least one inert filler chosen from silicon-based lamellar mineral fillers and a nonfunctionalized polyisobutylene oil, having a molecular weight of between 200 g/mol and 40 000 g/mol, present in a proportion of between 2 and 50 phe. | 01-20-2011 |
20110009657 | Method for the Synthesis of a Rare-Earth Organophosphate and Use Thereof for Preparing a Preformed Catalytic System - A process for preparing a rare-earth organophosphate in the form of a gel that can be used as is for the preparation of a “preformed” catalyst system intended, in particular, for the cis-1,4 stereospecific polymerization of conjugated dienes. | 01-13-2011 |
