Lise Durand 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).

  • Use of a deformable interface for the fabrication of complex parts
    Patent number: 11998985
    Abstract: An assembly for densification under load along at least one direction of compression. The assembly includes: at least one volume to be densified having a powdery and/or porous composition and having variations in thickness along the direction of compression; and at least one counter-form of a powdery and/or porous composition, having at least one face facing at least one portion of the volume. The face and each of the portions are separated by at least one deformable interface layer.
    Type: Grant
    Filed: May 13, 2022
    Date of Patent: June 4, 2024
    Assignees: Universite Toulouse III—Paul Sabatier, Centre National De La Recherche Scientifique

  • Method for manufacturing a part having a complex shape by flash sintering, and device for implementing such a method
    Patent number: 11045873
    Abstract: The invention relates to a method for manufacturing a metal, ceramic, or composite part (PF) by flash sintering, which comprises simultaneously applying, inside a die (M), a uniaxial pressure and an electric current to a device containing a powder constituent material, said uniaxial pressure being applied by means of at least two pistons (P1, P2) which slide toward one another inside said die and each of which has a bearing surface (F1, F2) contacting said material, said bearing surfaces engaging so as to define the shape of the part to be manufactured, characterised in that: said part has a complex shape, including at least one first slender portion (V), such as a rod, plate, bevel, or shell, and a second portion (B), such as a base, plinth, or solid part, which is not slender in the slender direction of said first portion, and in that said uniaxial pressure is applied in a direction (z) substantially parallel to the smallest dimension of said first portion of the part, or to one of the two smallest dimensio
