Abstract: A device for securing at least one insulating tube on a duct, includes an inner ring configured to be mounted on the duct, an outer ring coaxial to the inner ring, and a transverse web linking the inner and outer rings, the inner and outer rings and the transverse web forming two recesses, arranged on either side of the transverse web, each configured to receive an end of an insulating tube.

Abstract: A securing device includes at least one rigid ring configured to encircle the pipe, and at least one securing system, rigid and distinct from the ring, including a body which has a first contact face configured to be pressed firmly against and secured to a surface of a structure, and at least one groove in which the ring is housed, the groove being configured to allow the securing system to slide with respect to the ring in a direction of sliding along the ring, while being immobile or near-immobile relative to the ring in a plane perpendicular to the direction of sliding.

Abstract: A length-adjustable control rod includes a first part including a cylindrical peripheral face which has a succession of peripheral grooves separated from one another and positioned in transverse planes. A second part includes a barrel configured to at least partially receive the first part and which has several cutouts configured to divide up the barrel into several cylinder sectors and at least one inner rib, protruding from the inner lateral face of the barrel, which has a section configured to be housed in one of the peripheral grooves.

Abstract: In a moving turbine wheel, blade inserts are used with at least two blades interconnected by common outer and inner platforms and sharing a common root. The blade inserts have hollow roots in which respective recesses are formed, and the insert roots belonging to the same wheel and/or two different wheels are voluntarily given different configurations in order to adjust the resonant frequencies of the inserts to values that are significantly different, thereby ensuring that the inserts in the same wheel and/or between two different wheels are out of tune.
