Abstract: According to this method, each terminal is adapted to cover a coverage area. The method includes a step of sending a request-to-send data signal from a first terminal to a second terminal located in its coverage areas to advise the second terminal that the first terminal is requesting to send it data, and a step of sending a clear-to-send data signal to the first terminal to advise the first terminal that the second terminal is available to receive the data. The method further includes a step of a third terminal that has received the clear-to-send data signal and has not received the request-to-send signal sending a request-to-receive data signal to advise that it is available to receive data.

Abstract: The invention relates to methods for separating mixture components such as reactor effluent components. In particular, the invention relates to the use of an extractive agent such as a hydrocarbon in an extractive distillation process to separate monomers such as a C4-C7 isoolefins such as isobutylene from mixtures such as reactor effluents including one or more hydrofluorocarbon(s) (HFC).

Abstract: The composite vane is molded by injecting resin into a preform of layers of reinforcing fibers according to the RTM method. The skins of its main vane section as well as of its root and tip via which it is connected to the flow-straightener central body and to part of the duct are laminated with a pile of at least three layers of reinforcing fibers, and complementary piles at the root and tip exhibit at least one fastening tab. The central body is made of metal or composite and the composite vanes are interchangeable, or the vanes and the central body are injection-molded as a single piece using the RTM method.

Abstract: For producing connections made from composite material for structures having at least two hollow or non-hollow bars, interconnected by at least one hollow connecting joint, separate production takes place of blanks of said different parts with the definitive shapes, but in which the impregnation resin for the assembly of said blanks has not yet been introduced, after which they are assembled by thermosetting resin transfer molding, so as to produce the resin matrix of the connecting joint or the complete structure at the same time as the assembly. The blanks of the connecting joints are obtained by compressing a planar textile complex formed from hot preformable textile fibers between a cavity of a shaping mold and a countermold, by cutting and folding down onto the countermold the overlap parts and performing a thermal preforming cycle.
