  • Patent number: 7927091
    Abstract: A device for filling at least one mold with at least one powder. The device includes a mechanism to add at least one powder, at least one mechanism to eject the powder added into the device, in the form of a layer, and at least one deflector capable of locally intercepting at least part of the powder ejected in the form of a layer and redirecting the locally intercepted powder towards a determined location in the mold.

  • Patent number: 7192466
    Abstract: Nuclear metal or alloy particle preparation method and device; said device comprising: means to prepare a fluid mass of the metal or alloy by melting; means to put the fluid mass of the metal or metal alloy in the form of a molten metal or alloy stream; means to impart a centrifugal rotation movement to a quenching fluid and carry out the atomisation of the molten metal or metal alloy stream particles and the quick quenching of the particles; means to melt the nuclear metal or metal alloy in an inert gas atmosphere, and means to surround the molten metal or metal alloy stream by a neutral gas envelope until quenching.

  • Patent number: 7115336
    Abstract: The invention concerns an alveolar structure (1) comprising at least one alveolar zone (2a, 2b) partially delimited by an associated leak tight surface (4a, 4b) . According to the invention, each alveolar zone (2a, 2b) is formed of a plurality of metallic layers (8) superimposed parallel to the associated leak tight surface (4a, 4b), each metallic layer (8) comprising a network of passages (10) opening out on either side of said metallic layer (8). The invention further concerns a method for manufacturing said alveolar structure (1) Application to fuel cells and heat exchangers.
