Abstract: The present invention relates to a blade made of composite, comprising a vane formed of woven filaments impregnated with a thermosetting resin with a protective element in the region of the leading edge of the vane comprising a part in the form of a rigid strip, said strip being secured to the vane. The blade is characterized in that at least one layer of a viscoelastic material is at least partially interposed between said rigid strip and the vane so as to form, with the protective element, a means of damping the vibrations of the vane.

Abstract: A method and apparatus for aerating a liquid wherein the liquid to be treated is drawn down a vertical pipe at a predetermined velocity to entrain air bubbles into the moving liquid forming an air liquid mixture, maintaining the air bubbles in liquid contact for a minimum period under increasing hydrostatic pressure to dissolve the air and returning the aerated liquid to the reactor, the air bubbles being generated close to the surface of the liquid above the inlet of the vertical pipe.

Abstract: Network management information (NMI) contained in a first set of byte locations of a received frame is relocated to a second set of byte locations of another frame. The NMI is then transported through network elements using the second set of byte locations until the NMI is to be transported to a compatible network element, which can understand the NMI. At which time, the NMI is relocated back to the first set of byte locations of frames destined for the compatible network element. The relocation of the NMI from a first set of byte locations to a second set of byte locations allows the NMI to be transparently transported through incompatible network elements.
