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: An inclinometer for measuring a change in the inclination of a structure from a given initial position. The inclinometer comprises a frame, a pendulum and at least three distance-measuring device. The frame is rigidly connected to the structure such that the inclination of the frame has the same changes in inclination as the structure. The pendulum is freely suspended from the frame and comprises a first end attached to the frame and a freely moving opposite end. The distance-measuring devices at the frame have respective coplanar measuring axes converging at a single point. Each measuring device measures a change in the distance separating same from the pendulum.

Abstract: A tire for a heavy goods vehicle, having a tread having a tread surface provided in the new state with at least one groove delimited by opposing side walls, this groove opening onto the tread surface in a discontinuous manner by way of a plurality of portions that are open towards the exterior of the tread, these open portions having two ends that are extended under the tread surface by channels having inlets connected to the ends of the open portions, these inlets to the channels having a mean surface area S. This tread is such that each open portion on the tread surface is provided at each of its ends with a closure device for partially closing the cross section of the inlets to the channels when the tire is running and for leaving a passage unclosed.

Abstract: Disclosed is an apparatus and methodology for detecting anomalies in cables within a tire structure. A plurality of magnetic field sensitive sensors are aligned within a magnetic field provided by a magnet. The alignment of sensors and magnet is such that flux lines from the magnet are generally parallel to the plane occupied by the magnetic sensors. A tire cable anomaly present between the magnetic field sensitive sensors produces a detectable difference in signals produced by the magnetic field sensitive sensors as a result of the formation of perpendicular flux patterns produced by the anomaly. A signal processing circuit receiving input signals from the sensors evaluates differences between the signals from each of the plurality of sensors by pairing the output signal from each sensor with the output signal from each of the others of the plurality of sensors and produces an output signal upon the differences meeting selected criteria.

Abstract: The pole comprises a securing end, with device securing means and the device actuating means, a gripping end to be gripped by an operator and telecontrolling means for telecontrolling the actuating means. The actuating means are arranged in the device securing means and are directly controlled by the securing end of the pole and thus telecontrolled by the pole and its gripping end under the action of a thrust of the pole towards the support material. The device actuating means comprise safety means arranged to avoid by gravity the control of the actuating means by the securing end of the pole when the spatial position of the pole is inappropriate. The invention also relates to an anchoring device provided with the same safety means.

Abstract: Compositions and processes for development of sustainable materials based upon a method of thermoplastic polymer recycling with a solvent that is also a monomer for renewable polymer synthesis. By combining petroleum-derived polymers with bio-based monomer feedstocks, biphasic, blended polymer products are produced and are shown to exhibit facile tunability of physical and material properties. This one-pot, solvent-based recycling approach yields neat recycled products without the use of solvent evaporation or solute precipitation, and the functional utility of the resulting polymer blends greatly exceeds that of either homopolymer alone.

Abstract: A process for the synthesis of a diene copolymer comprising at least two blocks, at least one of the blocks being composed of a diene elastomer, characterized in that it comprises a stage of 1,3-dipolar reaction of two polymers defined as being: a) a diene elastomer bearing an alkyne functional group at one or each of its chain ends, and b) a polymer bearing at least one azide functional group. This process of synthesis can be adjusted, whatever the nature of the monomers necessary to form each of the blocks of the copolymer. Each block can be synthesized with an appropriate chemistry, independently of the other block.

Abstract: To characterize a behavior of a vehicle, a subjective behavior test is conducted on a given configuration of a suspension device and a wheel disc of the vehicle to determine whether the vehicle's behavior is acceptable. Modifications are made to the given configuration so as to sweep through pairs of values corresponding to a lateral force Fy and a lateral offset Dy of the wheel in straight-line running. For each modified configuration of the suspension device and/or the wheel disc, the subjective behavior test is conducted again. For each configuration of the suspension device and the wheel disc tested, a determination is made of a pair of values of the lateral force Fy and the lateral offset Dy of the wheel in straight-line running. Areas Z of acceptable behavior of the vehicle in a plane Fy, Dy are determined.

Abstract: A tire tread having a layered design is provided. In a first layer of the tread, sipes extend transversely to provide traction in the first stage of the wear life of the tread. In a second layer of the tread, the width of the sipes along the circumferential direction is increased to provide for improved traction in a second stage of the wear life. The increased width is provided by a void that opens to a circumferential groove only along one end. Because the void opens only along one end, a decrease in acoustical effects such as drive by noise can be provided.

Abstract: Systems and methods of determining tire uniformity parameters from piezoelectric tire sensor output signals obtained while operating in the counter-deflection zone include establishing a transfer function that relates a tire uniformity parameter to the piezoelectric output signals. Piezoelectric output signals from two or more piezoelectric tire sensors are then monitored to measure the voltage change from each piezoelectric tire sensor while it is operating in the counter-deflection zone. These output signals are correlated, and an actual tire uniformity parameter value is determined by applying the measured and correlated piezoelectric output signal voltage change levels to the established transfer function. Actual tire uniformity values are ultimately provided as electronic output to a user.

Abstract: A method for controlling the particle size of deposited fine particles in a fine particle production method is provided. The method introduces a fluid to be processed between at least two processing surfaces, which are disposed facing each other and are advancible and retractable, at least one of the two processing surfaces rotating relative to the other, to deposit fine particles in the thin fluid film formed between the two processing surfaces. The particle size of the fine particles is controlled by controlling the temperature of the fluid that contains the separated fine particles. The temperature control can be accomplished by providing a temperature adjusting apparatus and a jacket in the flow channel or receptacle for the fluid after outflow and controlling the temperature of the fluid that contains the deposited fine particles.
