| 20120097301 | METHOD OF IMPROVING TREAD NOISE - A method of improving tire tread noise is provided. The method allows the identification of locations where the tread pattern should be particularly modified in order to optimize the level of noise created by the tread during tire operation. Variations in a defined parameter, contact length ratio, are used to determine one or more locations in the tread pattern where modification for noise reduction can be made. The type of modifications needed can also be indicated. | 04-26-2012 |
| 20110180958 | Mould for Vulcanizing a Tire, Installation and Method for Regulating the Temperature of the Mould - A mould for vulcanizing a blank tire has an overall shape that is annular about an axis of revolution and includes a configuration for channelling a heat-transfer liquid in a substantially circular path about the axis. The channelling configuration includes an annular wall around the axis, separating at least two chambers in which the heat-transfer liquid circulates. Furthermore, a downstream end (respectively an upstream end) of one of the chambers has substantially the same angular position with respect to the substantially circular path as the downstream (respectively upstream) end of the other of the chambers. The mould is additionally configured for circulating the liquid in opposite directions in the two chambers. | 07-28-2011 |
