    摘要: High- or medium-voltage equipment comprising an induction-activated portion, a tank surrounding the active portion and filled with a dielectric fluid, such as oil, and passive acoustic reduction means for reducing acoustic waves coming from the active portion and propagating in the dielectric fluid. According to the invention, the passive means create an interference field that divides the propagated waves into two groups of waves of opposite phase that interfere with each other in a zone that is at a distance from the walls of the tank so as to at least limit the amplitude of the waves before they make contact with said walls. The equipment provides an effective solution for significantly reducing the noise that is propagated by the dielectric fluid medium.

    摘要: The present invention relates to a method of non-destructive inspection of mechanical structures (2) by using vibratory waves in order to detect local defects and/or changes of state. According to the invention, the method comprises: a first training stage in which a transient vibratory excitation is injected into an inspection zone (Z) and the received signals are picked up and time reversed in order to constitute reference excitation signals; a second training stage in which the reference excitation signals are emitted simultaneously and the resulting diverging signals are picked up in order to constitute reference response signals; and a stage of inspecting the mechanical structure (2), in which the reference excitation signals are emitted, the resulting diverging signals are picked up, and the diverging signals are compared with the reference response signals.

    摘要: According to the invention, a mandrel, provided with tabs for holding jars containing powders and for turning the jars upside down in order to empty them through the neck, is equipped with vibration generators for exciting the walls of the jar in order to shake off the powder masses adhering thereto. The method is much more efficient than even more energetic shock applications, and frequency scanning can further be advantageously applied. One application relates to an emptying step in methods for the production of nuclear fuel pellets by powder agglomeration.
