Abstract: A method for controlling the temperature of a first semiconductor device on an inverter module of a drive configured to drive an electrical machine is disclosed. The method comprises calculating at least one harmonic component of at least one power loss of at least the first semiconductor device; using the at least one harmonic component of the at least one power loss of the at least the first semiconductor device to calculate a temperature of the first semiconductor device; and if the calculated temperature of the first semiconductor device does not meet a predetermined temperature condition, issuing a command to control the operation of the drive such that the temperature of the first semiconductor device is changed to meet the predetermined temperature condition.

Abstract: The present invention relates to a tire tread comprising a rubber composition which improves the compromise between wear and durability of the tire, especially a tire intended to run off-road. The composition comprises: from more than 50 to 100 phr of a polyisoprene matrix, the polyisoprene matrix containing an epoxidized polyisoprene having a molar degree of epoxidation ranging from 5% to less than 50%, a carbon black and a silica, the weight of carbon black being greater than 50% of the total weight of carbon black and silica, from 0 to less than 2 phr of a coupling agent, and a crosslinking system. The epoxidized polyisoprene is an epoxidized natural rubber or an epoxidized synthetic polyisoprene having a molar content of 1,4-cis bonds of at least 90% before epoxidation, or a mixture thereof, and, if the epoxidized polyisoprene is an epoxidized polyisoprene having a molar degree of epoxidation of from 5% to 25%, the rubber composition contains more than 50 phr of epoxidized polyisoprene.

Abstract: A ready-for-use metal reinforcer, for example, of the wire or cord type, made of brass-coated carbon steel, is capable of adhering directly by vulcanization to a matrix of unsaturated rubber such as natural rubber. The surface of the reinforcer is provided with nanoparticles of at least one sulfide of a metal chosen from cobalt, copper, iron, zinc and the alloys comprising at least one of these elements. Such a reinforcer can be used as the reinforcing element of a finished article made of rubber, such as a tire.

Abstract: A drilling tool includes a spindle, a housing at least partly housing the spindle, a feed gear drivingly connected to a motor and threaded around the spindle to feed the spindle in an axial direction of the spindle by mutual rotation between the feed gear and spindle during a drilling process, and a micro peck unit which includes an undulated cam profile and a follower arranged to bear against the cam profile, and which produces an oscillating movement of the feed gear and the spindle upon rotation of the feed gear during a drilling process. The micro peck unit further includes interposable rolling elements arranged to be re-positioned into a gap between two circular contact surfaces in order to separate the cam profile from the follower, such that no oscillating movement is produced by the unit when the interposable rolling elements are positioned inside the gap between the contact surfaces.

Abstract: The tire has a tread with a tread surface and at least one groove which has a bottom wall and two lateral walls. At least one flexible wall is arranged in the groove in such a way that as liquid flows, the flexible wall flexes to allow the liquid to pass. After molding, the tire has a connecting element with a thickness which is equal to that of the bottom wall so that, after vulcanizing, the connecting element connects the lateral walls to the bottom wall over a given depth. The connecting element is then cut at its junction with each of the lateral walls of the groove so as to obtain the flexible wall.

Abstract: A method for testing a tire's resistance to pressure loss following a puncture includes inserting a plurality of puncturing objects through a wall of the tire, running the tire with the puncturing objects therein over a given distance with a regulated inflation pressure, stopping the running of the tire, and determining a pressure loss resistance index for each puncture based on an estimate of a leak rate of the puncture. In a first phase of the method, the puncturing objects are made up of pointed smooth-walled objects, such as nails, and the running is performed in such a way that the puncturing objects are not ejected during running. In a second phase of the method, the puncturing objects are made up of objects that are pointed but have walls bearing a screw thread, such as screws, and the running is performed at speeds of below 80 km/h.

Abstract: A method for determining the size distribution of a mixture of molecule or particle species including the steps of: injecting a sample of the mixture to be analyzed inside a capillary in which an eluent is flowing; transporting the sample injected along the capillary from an injection section to a detection section thereof, in experimental conditions suitable to generate a Taylor dispersion phenomenon that is measurable at the level of the detection section; generating, by a suitable sensor included in the detection section, a signal characteristic of the Taylor dispersion of the transported sample; processing the detection signal in order to obtain an experimental Taylor signal S(t); and analyzing the experimental Taylor signal ?(t), wherein the step of analyzing an experimental Taylor signal ?(t) of a sample of the mixture consists of searching an amplitude distribution P(G(c)) that allows the experimental Taylor signal ?(t)? to be broken down into a sum of Gaussian functions.
