Patents by Inventor Gauthier Demaret

Gauthier Demaret has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10391677
    Abstract: The present invention relates to a device for recycling carbon fibers (5), which includes two metal rails (1, 2) between which the carbon fibers (5) are intended to be stretched, and a current generator (3), the terminals of which are connected or intended to be connected to the two metal rails (1, 2). The rails (1, 2) form electrodes (1, 2) in short circuit when the carbon fibers (5) are arranged on said rails (1, 2). The generator (3) is suitable for outputting at least one current pulse of a power in the order of or greater than the MW between these two rails (1, 2), which allows the separation of the fibers from their resin. A recycling method implemented with this device is also proposed.

  • Patent number: 10280570
    Abstract: The invention concerns a method (100) for recovering and/or recycling a bituminous product by means of pulsed power, the bituminous product comprising bitumen and elements to be separated, involving the following steps: supplying (101) a reactor (11) inside which at least two electrodes (13) extend with the bituminous product and a liquid medium of which at least one liquid component has Hansen solubility parameters ??, ?? and ?d such that the bitumen is at least partially soluble in the liquid medium, the elements to be separated being insoluble, generating (102) a series of electromagnetic pulses between the electrodes (13) in the reactor (11) so as to produce, as a result of the power, the frequency and the switching time of the electromagnetic pulses, at least one shock wave and at least ultraviolet radiation, in such a way as to disperse and dissolve the bitumen in the liquid medium, and to separate the bitumen and the insoluble elements, the liquid medium preventing the reconstitution of the bitumen.
