  • Patent number: 11959418
    Abstract: An impeller (230) for a planet carrier of a planetary gear speed reducer of a turbomachine, is configured intended to be rotatably secured to the planet carrier and to be rotated about an axis A of the speed reducer. The impeller has an annular shape about the axis and includes lubrication means (43, 45, 238), in particular for lubricating bearings of planet gears of the speed reducer. The lubrication means include an annular cavity (238) situated at the inner periphery of the impeller. The impeller includes an inner peripheral wall (246) closing the cavity (238) in the radial direction, and the impeller includes an annular port (248) that extends around the axis and that opens in the axial direction into the cavity in order to supply it with lubricating oil.

  • Patent number: 11959953
    Abstract: A device is suitable for revealing spatial variations in polarization of an electromagnetic radiation, in a form of localized temperature variations. The device includes a surface of a carrier which is electrically and thermally insulating, and includes an array of patterns which each consist of at least one rectilinear segment of a sensitive material, of which the orientation is variable within each pattern or between neighboring patterns. Such device may be used with a thermal camera to reveal, in infrared images, temperature variations which are localized at segments not perpendicular to a local direction of linear polarization of the radiation.

  • Publication number: 20240084876
    Abstract: A planet carrier for a speed reducer of an aircraft turbomachine, the planet carrier including a cage carrier and a cage. The cage can have two parts: a first part having a wall and bridges, these bridges projecting axially from a face of this wall and including first axial ends connected to this face and second free axial ends; and a second part having another of the walls, this other wall including a face to which the free ends of the bridges are applied. The two parts of the cage can be attached together by screws.

  • Patent number: 6304919
    Abstract: The fixed frame comprises, on a side wall, a communication module. The communication module acts as interface between an external communication bus and indicating contacts whose state is representative of the connected or disconnected positions of a switchgear apparatus on the frame. The communication module is preferably fixed onto the external face of the wall, by the same fixing means as the indicating contacts. The wiring is thus reduced to the minimum when the apparatus is installed.

  • Patent number: 6246928
    Abstract: The interruption device, circuit breaker or contactor, comprises a communication module arranged in one of the locations designed for auxiliary contacts. The module is connected to the auxiliary contacts and to a communication bus to enable transmission of the states of the device to a supervision device, by means of the bus. The module can also act as interface between the bus and opening an closing control relays of the device, so as to enable remote control thereof by means of the bus.
