Patents by Inventor John D. Gurosik

John D. Gurosik 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).

  • Brazed component and method of forming a brazed joint therein
    Patent number: 10471530
    Abstract: A brazed part includes two or more components that are brazed together and has related method of making. Using a method of locating parts relative to one another, an inter-component gap between the components may be formed. Subsequently, during brazing, flow control features formed along the inter-component gap may then be used to assist in the retention of the braze material between the components during brazing.
    Type: Grant

  • Powder metal die filling
    Patent number: 9180518
    Abstract: The disclosed method provides a way to fabricate a powder metal compact implementing a top fill through one or more of the upper tool members. The top fill step allows for pre-compaction chamber, defined at least in part by at least one of the upper tool members, to be filled with a powder metal after the upper tool member is initially lowered, but before compaction of the powder metal. The manner in which the pre-compaction chamber is filled allows for the formation of complex geometries in powder metal compacts that are not obtainable using conventional lower tool powder transfer motions and further minimizes or avoids unacceptable variations in powder fill to final part ratios across the powder metal compact.
