Abstract: The invention relates to a method of sequencing commands to execute N sets of instructions, where N is a natural number greater than or equal to two, said method being implemented by a control unit suitable for periodically receiving time interrupts and for generating commands to execute the sets of instructions to be executed, said control unit comprising at least a main counter. The method comprises the steps of: a) initializing the main counter; b) incrementing the main counter upon receipt of a time interrupt; c) generating a command to execute a set of instructions to be executed, said set of instructions being selected based on an instantaneous value p of the main counter; d) repeating steps a) to d).

Abstract: A duct element configured to be used as a shapeable coupling element in a fluid flow line in any industrial application, for example within a rocket engine. The duct element includes a deformable tubular covering in a form of a bellows including inwardly projecting annular projections; and a protective sleeve including an end segment fastened in the tubular covering and including a free end that projects towards an inside of the tubular covering. The protective sleeve includes a plurality of other segments engaged in part one within another, each of the other segments including at a periphery of an outside surface thereof at least one attachment element fastened to the outside surface and that co-operates with at least one annular projection.
