Andrew D. Steinmetz 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: 11344981
    Abstract: A remanufactured internal spline component includes an inner surface defining a cylindrical bore and a remanufactured internal geometry on the inner surface. The internal geometry has a maximum diameter and a minimum diameter. The remanufactured internal geometry is created by removing a worn internal geometry to a pre-cladding diameter, cladding the inner surface in a plurality of layers by laser cladding to produce a cladded surface, and machining the cladded surface to produce the remanufactured internal geometry.
    Type: Grant
    Filed: November 23, 2020
    Date of Patent: May 31, 2022

  • Patent number: 10766831
    Abstract: A method for gas atomization of oxygen-reactive reactive metals and alloys wherein the atomized particles are exposed as they solidify and cool in a very short time to multiple gaseous reactive agents for the in-situ formation of a protective reaction film on the atomized particles. The present invention is especially useful for making highly pyrophoric reactive metal or alloy atomized powders, such as atomized magnesium and magnesium alloy powders. The gaseous reactive species (agents) are introduced into the atomization spray chamber at locations downstream of a gas atomizing nozzle as determined by the desired powder or particle temperature for the reactions and the desired thickness of the reaction film.

  • Publication number: 20170198577
    Abstract: A method for fabricating a rotatable cutting tool is disclosed. The method may comprise fabricating a body of a holder for the cutting tool, wherein the body of the holder extends along an axis and includes a head portion and a shank portion. The head portion may extend from a first end to a second end, and the first end may be configured to receive a cutting tip. The method may further comprise applying a plurality of rotation-assisting strips along an outer surface of the head portion that extend between the first end and the second end. The rotation-assisting strips may project from the outer surface of the head portion. The method may further comprise heat treating the holder having the plurality of rotation-assisting strips.
