Abstract: A turbine stator assembly including a guide vane assembly and a sealing ring bearing an abradable element of a dynamic sealing ring. The assembly includes pins secured to the sealing ring and cooperating with respective oblong openings formed in the guide vane assembly so as to allow a radial movement of the ring with respect to the guide vane assembly in order to compensate for differential thermal expansions. A seal is arranged so as to compensate for circumferential spaces between ring sectors forming the guide vane assembly.

Abstract: A counter-rotating turbine for a turbine engine comprising an inner rotor having an inner drum to which is attached a plurality of inner impellers rotatably supported by a first shaft, an outer rotor comprising an outer drum to which is fastened a plurality of outer impellers rotatably supported by a second shaft coaxial with the first shaft, the outer rotor comprising a downstream impeller having a plurality of downstream moving blades extending between an outer shroud and an inner shroud, one upstream end of the outer shroud being attached downstream of said outer drum, the inner shroud being attached to the second shaft, at least one of the inner shroud and of the outer shroud comprising at least one flexible transition part configured to allow elastic deformation of said shroud in the radial direction.

Abstract: The invention concerns an installation for nonwoven production, characterized in that it comprises a spunbonded web plant whereof the die is inclined at an angle of 10 to 60° and preferably of 20 to 50° relative to the displacement direction of a conveyor and preferably two spunbonded web plants whereof the dies have opposite inclinations, said conveyor whereon filaments are deposited from the die(s) in the form of a web, a station for compressing the thus formed web into a web compressed perpendicular to its plane, optionally a station for calendering the compressed web, followed by a station for consolidating by pressurized water jet spray the compressed and optionally calendered web with a jet spraying machine comprising a metal fabric whereof the wires have a diameter between 0.10 and 0.
