  • Patent number: 12297818
    Abstract: A hydraulic machine has a first assembly and a second assembly movable in rotation relative to each other along an axis of rotation. The hydraulic machine has a crankcase defining an internal volume, in which an interface between the fixed assembly and the movable assembly has a housing provided with a first sealing element ensuring the sealing of the internal volume relative to the external environment. A second sealing element is positioned between the internal volume and the housing. The second sealing element is adapted to allow a passage of fluid from the internal volume to the housing when the pressure deviation between the internal volume and the housing is less than or equal to a threshold value, and to isolate the housing from the internal volume when the pressure deviation is greater than the threshold value.

  • Patent number: 8177172
    Abstract: A cable raceway of this kind consists of lengths of wire-type cable raceway comprising both essentially rectilinear lengthwise or weft wires (2) and polygonal-shaped transverse or warp wires (4), with an opening formed in a corner and an even number of sides. Each length comprises at least four lengthwise weft wires (2) supported by at least four separate sides (6, 8, 10, 12) of the transverse or warp wires. For each lengthwise weft wire (2) there is a lengthwise weft wire (2) on the opposite side. The two corresponding lengthwise or weft wires (2) are located opposite each other, that is to say they are both in the same plane and the plane is approximately parallel to one of the lengthwise faces of the cable raceway.

  • Patent number: 8157235
    Abstract: This device for fixing a wire cable raceway onto a threaded rod (4) includes: a body (6) with support members (12; 54; 12?) featuring a first support surface and a second support surface opposite the first support surface, elements for fixing onto a threaded rod (4) including two elastic arms (8) each provided with a notch (20), the bottom of which is intended to cooperate with the thread of the threaded rod (4) in order to assure locking of the fixing device onto the threaded rod (4).

  • Patent number: 7523897
    Abstract: The fixing device can be used to fix a wire (10) to a support member having a planar surface provided with at least two openings. The device is made of elastic sheet-metal and includes a cut-out body which is bent into a U-shape and includes a web (33) and two flanges (34) whose ends are T-shaped. At least one arm of the T-shape at each end is adapted to bear on the surface of the support member that is opposite the planar surface at the edge of an opening.

  • Patent number: 7461493
    Abstract: Securement bracket including a base plate and a cylindrical body; the base plate (11) and the cylindrical body are of a single piece, the cylindrical body including two opposite walls called median wings (12, 13) in prolongation at 90° from the base plate (11) and two other opposite walls called flaps (16, 17) in prolongation at 90° from the median wings (12, 13), which have at least one opening in which is disposed a tongue (23) provided at the end of the flaps (16, 17). A process for production of such a bracket and cutout plate for the practice of the process are disclosed.

  • Patent number: 7387287
    Abstract: A fixing device which can be fixed to a surface such as a ceiling and receive a perforated section comprises a plate for fixing it to the surface and a support for receiving the perforated section. The support has a wall substantially perpendicular to the plate and at least two claws with the same orientation which cooperate with corresponding perforations of the perforated section. The wall includes a precut locking lug which can be bent into another perforation and cooperate with an edge of that perforation to immobilize the perforated section against movement in translation.

  • Patent number: 6570092
    Abstract: A wire cable duct includes a grid made up of wires of two different types, namely longitudinal wires which run longitudinally the entire length of the duct and U-shaped transverse wires disposed transversely to the longitudinal wires, from place to place along their length and appropriately attached thereto. The resulting trough-like combination forms three panels, namely a bottom panel and two side panels. The side panels include a longitudinal row of successive planar and substantially rectangular edge meshes which constitute upper parts of the side panels, each of which is defined between two facing flange portions of two consecutive transverse wires, and each of which includes at least one anti-flexing member to limit its flexing about an axis perpendicular to its plane.
