Abstract: Device for transferring a reinforcing ply having the overall shape of a parallelogram and containing reinforcing threads with ferromagnetic properties and making a given angle b, smaller than 90°, with the longitudinal direction of the said reinforcing ply, comprising at least two transfer belts which overlap over a given length l and are separated by a given and small-sized distance, each of the belts comprising a magnetized region of trapezoidal shape, the bases of which are parallel to the longitudinal direction of the belts and are intended to hold the reinforcing ply firmly against the moving surface of the said transfer belts, characterized in that, in the region of overlap of the belts, the side of the trapezium connecting the two bases of the magnetized region of the first belt forms an angle a1 with the longitudinal direction which is smaller than the angle of the threads b, and the side of the trapezium connecting the two bases of the magnetized region of the second belt forms an angle a2 with the l

Abstract: A tire tread provided with a plurality of grooves delimiting blocks and/or ribs and having an average depth H. This tread has a tread surface designed to come into contact with the roadway only along a plurality of raised contact lines. The raised contact lines intersect one another to delimit, on the tread surface, a plurality of contiguous first cavities each formed by a wall which is recessed radially inwardly from the tread surface. The walls of the first cavities are intersected by respective second cavities situated radially.

Abstract: A tire pressure monitoring apparatus includes a pressure transducer having a housing and a valve stem secured to the housing. The valve stem projects through an opening in a wheel for holding the tire. A retention clip is secured to the valve stem. The retention clip includes a plurality of spring retention members for engaging the opening in the when the valve stem projects through the opening. The retention members are deflected when the valve stem projects through the opening and have resilient properties that spring bias the retention members against the wheel to help retain the tire pressure monitoring apparatus on the wheel.
