A device for centering a tube inside a hollow shaft is disclosed. The device includes a deformable device interposed between the tube and the hollow shaft and including bearing members for bearing against the inside surface of the shaft and suitable for being spaced away from the inside surface of the shaft in order to enable them to be moved inside the shaft. The deformable device is made of a shape-memory material suitable for deforming to press the bearing members against the inside surface of the shaft or to space them away therefrom on being subjected to a predetermined temperature.

An adaptable-tool hook comprises a wire-frame buckle and hook with a strap. The strap can be positioned on the buckle-hook in two different orthogonal positions to allow the strap to wrap an object or tool laterally or longitudinally. The hook stays with the tool and can be hooked on any available belt, pocket, rail, or wire.

A continuous method for the treatment of a spent aqueous caustic stream used to scrub a hydrocarbon process stream to remove oxidizable sulfur-containing compounds includes:a. mixing an oxidizing hypochlorous acid stream produced from an aqueous brine solution with the aqueous caustic stream to form a reactive mixed feedstream;b. contacting the reactive mixed feedstream with at least one catalyst to promote the oxidation of the sulfur-containing compounds and the neutralization of the sodium hydroxide; andc. recovering a neutral treated product stream comprising aqueous sodium sulfate, sodium carbonate and sodium chloride that is odorless, non-toxic and environmentally acceptable for discharge into the sea or into a conventional sewage treatment system.Preferably, the hypochlorous acid is produced by an electrolyzer that also produces a (1) hydrogen stream that is directed to a PEM fuel cell to generate at least a portion of the electrical power requirement of the electrolyzer, and (2) water that is combined with fresh sodium hydroxide from the electrolyzer to form a fresh caustic stream for use in scrubbing the hydrocarbon process stream.

A device for feeding air and fuel to a burner ring in an after-burner chamber, including a plurality of flame-holder arms extending radially about the axis of the chamber from an outer casing, and a burner ring made up of ring sectors mounted substantially end to end on the flame-holder arms, the ring sectors containing fuel feed rail and air manifold boxes.

A link part for a turbine engine which mounted between a fan cone and a fan disk supporting fan blades is provided. The link part includes an annular wall pierced by a plurality of orifices, each orifice for receiving a fastener member and terminated by a substantially perpendicular rim having an outer surface that provides an aerodynamic extension of the fan between an outer surface of the fan cone and an outer surface of a fan blade platform. The annular wall is made of a first material that is composite and is provided on an inner surface of the rim with a ring made of a second material that is different from the first and that is suitable for radially retaining the fan blade platform.

A device for lubricating a component in a turbomachine, in particular a shaft bearing in a turbojet, the device comprising an annular support part defining a lubrication chamber around the component, an annular cover mounted in sealed manner on the part and including a lubricating oil inlet, and an annular channel for passing a flow of pressurizing and cooling air, which channel is formed between the part and the cover, and communicates with ducts in the support part and an annular enclosure formed in the cover for passing the pressurizing and cooling air.
