Abstract: A device (1) for supporting and moving furniture doors, in particular flap doors, comprises a first fixed part (2) intended to be secured to the body of a piece of furniture (30), a second part (3) intended to be secured to a door (33), articulated connection means (4) movable in a moving plane to connect said first fixed part (2) to said second part (3), elastic means (5) suitable to act through kinematic connection means (7) on a push lever (11) of said articulated connection means (4) to push said device (1) with a predetermined elastic load toward an extended open door configuration after a first portion of the movement of said device (1) from a retracted configuration toward said extended configuration, wherein said elastic means (5) and said kinematic connection means (7) lie in a plane perpendicular to said moving plane for said articulated connection means (4).

Abstract: The invention relates to a shoe (10) on an electrical power supply track for an electric railway vehicle, the shoe (10) comprising: a power supply flange (12) movable between a retracted position and a deployed position; an actuator (11) able to move the flange between the retracted and deployed positions; and a mechanical system (13) connecting the flange to the actuator; characterized in that the actuator (11): has a movement speed such that it is able to move the flange (12) between its retracted and deployed positions in a time period shorter than or equal to 1 second, and preferably shorter than or equal to 0.5 seconds; and has a number of operating cycles before failure greater than or equal to 2,500,000.

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: A cantilever supports a catenary to supply energy to a vehicle. The cantilever includes a cross-member adapted to be attached to a support structure, the cross-member extending along a longitudinal axis (X-X), and at least one attachment connected to the cross-member. The cross-member includes an outer surface, the outer surface including at least a first side having a non-circular shape in a section plane (II-II) that is orthogonal to the longitudinal axis (X-X). The attachment includes at least one collar encircling the cross-member, and the collar includes at least one contact face in contact with the at least first side.
