Thomas William Farthing 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).

  • Removal of substances from metal and semi-metal compounds
    Patent number: 7790014
    Abstract: The present invention pertains to a method for removing a substance (X) from a solid metal or semi-metal compound (M1X) by electrolysis in a melt of M2Y, which comprises conducting the electrolysis under conditions such that reaction of X rather than M2 deposition occurs at a electrode surface, and that X dissolves in the electrolyte M2Y. The substance X is either removed from the surface (i.e., M1X) or by means of diffusion extracted from the case material. The temperature of the fused salt is chosen below the melting temperature of the metal M1. The potential is chosen below the decomposition potential of the electrolyte.
    Type: Grant
