Abstract: The aspects disclosed herein relate to a tread for a tire including at least one block of rubbery material of width W and length L with L»W. This block extends in a circumferential direction (X) when the tread is mounted on the tire, the block including a contact surface intended to come into contact with the ground and a first lateral wall and a second lateral wall delimiting this contact surface. The block further includes a plurality of sipes opening onto the contact surface of the block, with each sipe extending over the contact surface in an oblique direction opening onto the first lateral wall and onto the second lateral wall, the sipes of the block being oriented in the same direction. The sipes are distributed over the contact surface of the block in such a way that when one sipe reaches the second lateral wall another sipe starts out from the first lateral wall at the same circumferential level (N) on the block, and each sipe includes at least two parts.

Abstract: A tire has a form of a torus that is open radially on an inside portion. The tire includes inner and outer walls, a crown, two sidewalls, two beads, a crown reinforcement, and a carcass reinforcement anchored in the beads and extending at least from the beads as far as the crown. The inner wall is covered at least in part with an airtight layer, and the airtight layer is covered at least in part with a layer of a self-sealing product. Each of the beads includes an annular reinforcing structure, with each annular reinforcing structure being formed of a plurality of windings of a single metal thread. The windings are arranged in a plurality of radially superposed layers, with each layer having a group of the windings arranged axially in a side by side manner, such that the superposed layers have a hexagonal cross section.

Abstract: Disclosed herein is a tread for a tire. The tread includes at least one elongate block of rubbery material of width W and length L with L>>W. This elongate block extends in a circumferential direction (X) when the tread is mounted on the tire. The elongate block includes a contact surface intended to come into contact with the ground and a first lateral wall and a second lateral wall delimiting this contact surface. The elongate block includes a plurality of sipes opening onto the contact surface of the elongate block, with each sine extending in an oblique direction opening onto the first lateral wall and onto the second lateral wall. The sipes are distributed over the contact surface of the block in such a way that when one sipe reaches the second lateral wall another sipe starts out from the first lateral wall, at a same circumferential level (N) on the elongate block. With the sipes delimiting sub-blocks in the elongate block, at least two of these sub-blocks are configured differently in the tread.

Abstract: The run-flat tyre (P1) comprises a carcass reinforcement (32) comprising at least one polyester reinforcing element and a sidewall insert (44) manufactured from a rubber composition based on a crosslinkable rubber composition comprising an elastomer consisting of polybutadiene having a Mooney plasticity within a range of values extending from 55 to 85 Mooney units and a carbon black having a specific surface area within a range of values extending from 15 m2/g to 25 m2/g and an oil adsorption number of compressed sample within a range of values extending from 65 ml/100 g to 85 ml/100 g.

Abstract: A tyre, which is designed to be able to run flat, includes a carcass reinforcement. The carcass reinforcement includes at least one reinforcing element. Each reinforcing element includes at least one multifilament plied strand made of aramid and at least one multifilament plied strand made of polyester. The at least one multifilament plied strand made of aramid and the at least one multifilament plied strand made of polyester are twisted together.

Abstract: The disclosure concerns an elastic articulation designed to be linked to a vehicle body suspension arm and capable of operating in torsion and of carrying a substantial part of the body weight, comprising an inner reinforcement 8, an outer reinforcement 9 enclosing the inner reinforcement, and an elastomeric sleeve 7, arranged between the inner and outer reinforcements and whereof the inner and outer peripheral surfaces are linked without any possibility of sliding to said inner and outer reinforcements. The disclosure is further characterized in that the outer reinforcement 9 is configured so as to be able to be fixed directly to the body of a vehicle, without any intermediate rigid support part.

Abstract: The disclosure concerns an elastic articulation designed to operate in torsion and comprising an elastomeric sleeve (7) whereof the inner and outer peripheral surfaces are linked without any possibility of sliding respectively to inner (8) and outer (9) reinforcements, and which is configured such that the articulation should have a minimal radial rigidity along a first reference axis Z′ of a system with three reference axes X′, Y, Z′ whereof the second reference axis Y merges with the axis of the elastic articulation (5), at least one of the two end surfaces (7a) and (7b) of the sleeve (7) has a profile which continuously moves in the circumferential direction of the sleeve between at least a minimum and at least a maximum, the minimum or minima and the maximum or maximums of the profile in the inner peripheral zone of the end surface being offset by a predefined angle respectively relative to the minimum or minima or to the maximum or maximums of the profile in the outer peripheral zone of

Abstract: The invention relates to a process for coloring surfaces in such a way that two juxtaposed colored areas cannot be visually perceived as distinct from one another unless their distance from the eye drops below a predetermined distance. The first area is colored by juxtapositioning unitary zones of at least two colors and the second area is colored by the resultant color of the optical mixture of the colors used for the first area. One important application of the invention is in display advertising.
