Patrice Rene Sagne 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: 8206644
    Abstract: A device for implementing a method of sizing a cylindrical part following shaping, by plastic deformation, of a metallic material that has maximum structural shrinkage at a maximum-shrinkage temperature between a first temperature and a second temperature, which is lower than the first temperature, is disclosed. The method includes placing the part in a shaft furnace, heating the part to the first temperature, lowering and fitting into the part an internal-sizing tool with an outer diameter greater than an inner diameter of the part at maximum structural shrinkage, transporting the assembly formed by the part and the sizing tool to a tempering vessel, cooling the part to a temperature below said second temperature, and extracting the internal-sizing tool. The method applies to the manufacture of turbomachine casings.

  • Patent number: 7454941
    Abstract: The invention relates to an upsetting method for working a metal slug having a determined slenderness, characterized by the fact that the slug is at least partly positioned in the direction of its length, in an upsetting pot in a cylindrical housing provided for this purpose, and pressure is exerted on the slug in the direction of its length by means of a punch, until the slug fills the whole section of the housing, so as to reduce its slenderness, and to obtain a cylindrical slug with a section equal to that of the housing, in preparation for a forging operation. By this method, it is possible to upset slugs with large slenderness.
