Patents by Inventor Dale P. Barkey

Dale P. Barkey 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: 9689064
    Abstract: The present disclosure relates to a method of incorporating lithium into a coating. One may supply a substrate having a coating containing aluminum ions and immersing the substrate including the coating containing aluminum ions in a water-soluble diketone including lithium for exchange where the ketone carbonyls are separated by at least one carbon atom. This may then be followed by exchanging a portion of the aluminum ions with lithium ions from the diketone solution. Such coatings may have improved chemical resistance.
    Type: Grant

  • Patent number: 4886598
    Abstract: This invention relates to a method for improving the performance of liquid embrane separations by coating a liquid membrane onto solid ion-exchange resin beads in a fixed bed. Ion-exchange beads fabricated from an ion-exchange resin are swelled with water and are coated with a liquid membrane material that forms a film over the beads. The beads constitute a fixed bed ion-exchange column. Fluid being treated that contains the desired ion to be trapped by the ion-exchange particle is passed through the column. A carrier molecule, contained in the liquid membrane ion-exchange material, is selected for the desired ion in the fluid. The carrier molecule forms a complex with the desired ion, transporting it through the membrane and thus separating it from the other ions. The solution is fed continuously until breakthrough occurs at which time the ion is recovered, and the bed is regenerated.
