Abstract: A switching device, including: a main switch configured to be displaced between a closed position of a main circuit and an open position, a vacuum interrupter including: a fixed electrode, a mobile electrode, configured to be displaced between: a first, so-called closed, position, and a second, so-called open, position, in which the electrodes are apart, a palette configured to make the mobile electrode switch over from the first position to the second position and comprising an electrically conductive plate, the main switch being configured to drive the palette via the plate, a connection wire electrically linking the plate and the mobile electrode, the wire being in electrical contact with a tube disposed in an accommodating recess of the plate, wherein the accommodating recess comprises a wall exerting an elastic holding force on the tube.

Abstract: A tank for a medium-voltage electrical unit that is intended to contain a gas under a pressure greater than atmospheric pressure, the tank having: a structure that has uprights, panels that are secured to the uprights, the panels being set up to receive a pressure force of the pressurized gas, at least one metal reinforcing rod extending in a longitudinal direction, the reinforcing rod connecting together two uprights so as to counter a deformation of the uprights under the action of the pressure force of the gas, at least one first electrically insulating tube, wherein at least one longitudinal portion of the reinforcing rod is surrounded by the first insulating tube, and wherein an inner surface of the first insulating tube is remote from a lateral surface of the reinforcing rod.

Abstract: To simplify connection between electrical apparatuses, a connecting bar has been developed wherein the connection interfaces are flat. The connection devices comprise a conducting insert in a compressible insulating elastomer molded from casting, which is coated with a shielding. The connecting surfaces of the conducting inserts are located withdrawn with respect to the connection surfaces of the insulating support. When connection is performed, the insulating surfaces come into contact, compression is then performed enabling the interface to be made air-tight, while at the same time bringing the conducting surfaces into contact. The assembly is kept compressed by means of a central screw which is preferably associated with a blanking device of cover type for the connection surface not used for electrical connection.

Abstract: A brake device for the rotor of a helicopter, the device associating a mechanism having a disk and a manual control for main braking of the rotor, and a mechanism for secondary braking of the rotor under strong wind. The secondary braking device includes a secondary lever hinged to the body and capable of being actuated against secondary return elements to drive a bearing finger against a main lever of the main brake mechanism and cause the jaws of the mechanism to move correspondingly towards each other so that the secondary lever actuates the main lever in order to amplify the clamping forces applied to the disk by the jaws in comparison with the forces they exert when driven by the main lever alone.

Abstract: The invention relates to a suspension system for a set of vehicle wheels with rigid axle, said suspension system comprising, on the one hand, a longitudinal torsion tube articulated at one of its ends on the chassis of the vehicle so as to be able to pivot about a transverse horizontal axis without possibility of rotating about its longitudinal axis and fast at its other end with said rigid axle and, on the other hand, two longitudinal elastic blades which are disposed laterally each on one side of said torsion tube and of which each is fixed at one of its ends to said axle, is pivoted in its intermediate part on said chassis about a transverse axis and is in abutment at its other end against said chassis. The invention is more particularly applicable to a suspension for road tractor.

Abstract: Suspension for a two-sheeled undercarriage of a vehicle comprising two arms pivotable about an axis transversal to said vehicle, each arm carrying one wheel, and an assembly of tubes of axes parallel to said transversal axis and made of a composite material of fibers and synthetic material.The suspension according to the invention is remarkable in that said assembly comprises a first tube integral with the vehicle chassis by each of its ends, and about which tube each arm can pivot, as well as two second tubes integral by each of their ends with one of said arms, said first tube and said second tubes being interconnected in their middle part.
