Patents by Inventor Michael John King

Michael John King 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: 11239507
    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. Spent electroprocessing solvent and/or base utilized to treat lead paste from the lead acid battery scrap can be recycled to the recovery process.
    Type: Grant
    Filed: May 9, 2019
    Date of Patent: February 1, 2022
    Assignee: AQUA METALS INC.
    Inventors: Brian Dougherty, Michael John King, Robert Lewis Clarke, Stephen R. Clarke, Michael David Hurwitz
  • Patent number: 10689769
    Abstract: The inventive subject matter is directed to continuous electrochemical production of highly pure micro- or nanostructured lead that at least partially encloses the electroprocessing solvent and molecular hydrogen and optional guest compounds to form a mixed matrix. Such compositions are particularly suitable for cold forming of various structures and/or for alloy and composite material production.

  • Publication number: 20080164427
    Abstract: The present invention relates to components in ion implanters having surfaces adjacent to the path of the ion beam through the ion implanter. Such surfaces will be prone to deposition and the present invention addresses problems associated with delamination of deposited material. An ion implanter component is provided that has a surface defining at least in part an ion beam path through the ion implanter, wherein at least a portion of the surface has been roughened. The portion of the surface may be roughened to provide surface features defined at least in part by sharp changes in orientation of adjacent parts of the surface.
