James D. Fritz 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).

  • Publication number: 20210036273
    Abstract: The disclosure provides seals for devices that operate at elevated temperatures and have reactive metal vapors, such as lithium, sodium or magnesium. In some examples, such devices include energy storage devices that may be used within an electrical power grid or as part of a standalone system. The energy storage devices may be charged from an electricity production source for later discharge, such as when there is a demand for electrical energy consumption.
    Type: Application

  • Patent number: 6709528
    Abstract: A method of enhancing the corrosion resistance of an austenitic steel includes removing material from at least a portion of a surface of the steel such that corrosion initiation sites are eliminated or are reduced in number relative to the number resulting from processing in a conventional manner. Material may be removed from the portion by any suitable method, including, for example, grit blasting, grinding and/or acid pickling under conditions more aggressive than those used in conventional processing of the same steel.

  • Patent number: 6576068
    Abstract: A method for producing a stainless steel with improved corrosion resistance includes homogenizing at least a portion of an article of a stainless steel including chromium, nickel, and molybdenum and having a PREN of at least 50, as calculated by the equation: PREN=Cr+(3.3×Mo)+(30×N), where Cr is weight percent chromium, Mo is weight percent molybdenum, and N is weight percent nitrogen in the steel. In one form of the method, at least a portion of the article is remelted to homogenize the portion. In another form of the method, the article is annealed under conditions sufficient to homogenize at least a surface region of the article. The method of the invention enhances corrosion resistance of the stainless steel as reflected by the steel's critical crevice corrosion temperature.
