Selwyn Mould 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).

  • Devices and method for smelterless recycling of lead acid batteries
    Patent number: 10665907
    Abstract: Lead from lead acid battery scrap is recovered in two separate production streams as clean grid lead and as high-purity lead without smelting. In preferred aspects, lead recovery is performed in a continuous process that uses an aqueous electroprocessing solvent and electro-refining, and spent electroprocessing solvent can be recycled to the recovery process.
    Type: Grant
    Filed: November 13, 2017
    Date of Patent: May 26, 2020
    Assignee: Aqua Metals Inc.
    Inventors: Stephen R. Clarke, Robert Lewis Clarke, Michael David Hurwitz, Michael John King, Selwyn Mould
