Abstract: A metering device which includes a storage reservoir 3, a volumetric extror 30 introducing roughly gauged batches of material into an intermediate hopper 4, which empties periodically into a weighing hopper 1. Under the latter, rapid stabilization scales 2 record the weight of the batch contained in the weighing hopper 1. The latter is emptied onto a belt 5 at the end of a time interval proportional to the weight of the batch or of one of the preceding batches.

Abstract: A method of processing signals in a system for the monitoring of the tires f a vehicle in which the time necessary in order to obtain a cold state of the tires as a function of the previously identified conditions of use of the vehicle before it was stopped is determined. The method allows verification of the natural losses and variations in climate of the tires of the vehicle.

Abstract: In order to improve the resistance to separation between the ends of the working plies (31 to 34) of a crown reinforcement (3) and between the edges of said reinforcement (3) and the radial carcass reinforcement (2), the said plies have axial widths which are different from each other, and at least two of the widths are greater than the axial distance (L) between the median axes (XX') of the two lateral grooves (6) closest to the edges of the tread (1) and defining lateral regions (7) where the tread (1) has a meridian profile (8) radially recessed with respect to the meridian profile (9) of the geometrical envelope of its median zone.
