    Abstract: A tensioning device includes a circular spring, and a pulley rotatably connected to the circular spring. The pulley includes a circumferential groove, which has a V-shaped cross-section defined by two lateral converging walls. The pulley also includes a flexible rope having a variable cross section, extending between a first end connected to the pulley and a second end intended to be connected to the cable. The pulley is rotatably movable around an axis, between a first position in which the flexible rope is arranged in the circumferential groove around the axis, and a second position in which the flexible rope is unwound.

    Abstract: This electrical switching apparatus has at least two power components each including first and second power transistors. A driver control device of the transistors is configured to deliver a first control signal to each of the first transistors and a second control signal to each of the second transistors, and an electrical interconnect device connecting the driver control device to the power components. The interconnect device includes several electrically conductive plates extending parallel to one another, each being connected between a control electrode of one of the first or second power transistors and a corresponding output of the driver control device.

    Abstract: The present invention concerns an insulating joint for electrically insulating a pair of adjacent rail sections of a railway track, each rail section extending along a longitudinal axis and defining at least one connecting surface substantially perpendicular to the longitudinal axis and a plurality of lateral surfaces extending along the longitudinal axis. The insulating joint comprises a joint body having substantially the same cross section as the rail sections and defining two contacting surfaces, each contacting surface being intended to be in contact with the connecting surface of one of the rail sections. The joint body is made from an insulating material comprising a reinforcing structure made of metal or carbon fibers, the reinforcing structure being placed inside of the joint body with a distance from the contacting surfaces.
