Abstract: The invention relates to a signalling device (1) for an aerial transmission line (2) comprising two signalling elements (3, 4) which are configured to be mounted one against the other around a conductor portion (2) of the transmission line, in which at least one of the two signalling elements (3, 4) comprises at least partially an outer signalling coating in the context of air safety, which device is characterized in that the two signalling elements (3, 4) are at least partially electrically conductive and at least one of the two signalling elements (3, 4) comprises a clamping means (5) which is configured to clamp the conductor portion (2) of the transmission line. The invention also relates to a method for assembling such a device on a high-voltage aerial transmission line.

Abstract: An electrical connector for connecting a conductor with three fixations and particularly suitable for medium and high voltage applications. The connector body includes a body part with an inner profile adapted to receive the conductor and a cover part provided with two keepers that are fastened to the body part for providing the first and the second fixation of the conductor to the body part, respectively. The third fixation of the conductor is provided by an inner keeper that is partially covered by the two outer keepers. The inner keeper includes a contact element that is disposed transversally over the conductor and attached to the body part by a U-bolt. The outer keepers and the inner keeper are shaped so that at least one of the outer keepers covers, at least partially, the inner keeper.

Abstract: A method for damping control of oscillating modes of a continuously variable transmission which is provided with an electric variator by using a heat engine and at least two electric machines. In the method a torque controller of the electric machines is embodied in a form of a sum of a main instruction enabling to attain set torque on a wheel, heat engine torque, and an additional instruction for damping oscillating modes generated by stiffness of a kinematic chain between the heat engine and the wheels.

Abstract: A control process for mode change decisions for an infinitely variable transmission with several modes of operation including at least two parallel coupling paths, each containing a closed coupler for the first mode of operation and open for a second mode of operation, with the two couplers being closed simultaneously during a delay period during the mode changes, wherein the mode change decision is imposed onto the transmission if the speed differential at the terminals of the coupler to be closed to change the mode, exceeds a first pre-established threshold.

Abstract: A rotor for a motor having magnets, the rotor comprising a rotary shaft and at least one pair of magnetic poles with magnets disposed therebetween having azimuth magnetization, the rotor being characterized in that the poles and the magnets are fixed to each other and to the rotor by a section member (30) of constant thickness having a section with as many lobes (31, 32, 33, 34) as there are poles in the motor, said lobes being interconnected in pairs by curved portions, (41, 42, 43, 44) which are substantially circular arcs of diameter close to that of the shaft (1) of the motor. The invention is applicable to a synchronous motor having magnets.
