  • Patent number: 8192149
    Abstract: A turbojet turbine or compressor stage is disclosed. The stage includes at least one rotor disk mounted inside a sectorized ring supported by a casing and including a circumferential flange radially clamped on an annular rail of the casing by a substantially C-shaped cross-section annular locking device which is axially engaged on the casing rail and on the flange of the ring. A substantially cylindrical heat shielding foil is interposed between the ring and the device. The foil or the device includes at least one extra thickness which respectively bears on the device, or the foil, to radially immobilize this foil.

  • Patent number: 6240755
    Abstract: The invention proposes a handle for the door of an automobile vehicle, of the type in which the handle comprises an external gripping lever that is designed to be moved by a user from a rest position to an open position to control a lock that is associated with a lock cylinder of the type comprising a stator, one end of which is accessible from the outside so that a key can be inserted in the lock cylinder through a slit that opens out into the end of the cylinder, wherein the gripping lever comprises a protective cap and/or trim covering the lock cylinder that is assembled so that it is free to slide with respect to the gripping lever between a normal assembly position in which the cap conceals at least the slit in the lock cylinder when the gripping lever is in its rest position, and a displaced position enabling access to the key insertion slit.
