Irene Nava 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: 9593595
    Abstract: A method is provided for remanufacturing a machine component having multiple holes. The holes are provided to match in alignment with corresponding holes of an adjacent component in a machine assembly. First and second sets of holes are selected from the holes of the machine component on the basis of being located within first and second limits of positional tolerance with respect to corresponding holes of the adjacent component. Each hole from the first set of holes is bored to define openings in axial alignment with holes of the adjacent component. Each hole from the second set of holes is bored to an enlarged diameter and then plugged with a deformable insert. Each of these inserts is then drilled to define openings in axial alignment with holes of the adjacent component.

  • Publication number: 20050281668
    Abstract: In order to minimize a clearance between a turbine and its housing, and thus, improve the efficiency of a turbine engine, an abradable coating can be applied to an inner surface of the turbine housing. However, there are no known abradable coatings that can be applied to a housing that is subjected to temperatures between 950-1500° F. for extended periods of time. The apparatus of the present disclosure includes a housing including a 950-1500° F. section in which at least one rotating blade row is positioned. The rotating blades and the 950-1500° F. section each includes a surface being comprised of a relatively non-abradable material. The surface of the housing comprised of the relatively non-abradable material is covered by a 950-1500° F. relatively abradable coating that includes a metallic matrix and at least one of a thermoplastic and dry lubricant. The metallic matrix is 55-85% of the coating by volume.
