Patents by Inventor Gyan Jha

Gyan Jha 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).

  • Shaped direct chill aluminum ingot
    Patent number: 9023484
    Abstract: Method and apparatus for forming aluminum ingot having shaped ends to avoid alligatoring during rolling.
    Type: Grant
    Filed: June 25, 2008
    Date of Patent: May 5, 2015
    Assignee: Tri-Arrows Aluminum Inc.
    Inventors: Gyan Jha, J. David Brown, Shridas Ningileri, Weimin Yin, Randall Bowers
  • Production of specialty aluminum alloys using partition of feed impurities
    Patent number: 8992661
    Abstract: A series of inventions leading to the production of specific aluminum alloys (especially aluminum beverage can sheet product) through novel approach of introducing, selectively partitioning and managing alloying elements. This invention also enables manufacturing practices to enhance the performance characteristics of aluminum alloys produced. The selected elements can be derived from carbon anodes made from calcined petroleum coke with high metallic contents (such as nickel and vanadium). Alloying elements can also be introduced and managed from other raw material such as alumina and bath constituents added during aluminum smelting process. Additionally, cell operating parameters, such as cell temperature, off gas flow rate, aluminum tapping rate and impurity partition characteristics can also be manipulated to produce low cost aluminum alloys and facilitate utilization of high metallic content calcined petroleum coke.
