  • Patent number: 10857596
    Abstract: A method of producing an abrasive tip for a turbine blade includes producing or obtaining a metal powder that is mixed with an abrasive ceramic powder and producing or obtaining a metallic mold that is in the shape of an airfoil. The metallic mold includes a hollow interior portion. The method further includes sealing the metal and ceramic powder mixture within the hollow interior portion of the metallic mold under vacuum and subjecting the sealed mold to a hot isostatic pressing process. The hot isostatic pressing process compacts and binds the metal and ceramic powder mixture together into a solid article in the shape of the airfoil. Still further, the method includes slicing the solid article into a plurality of airfoil-shaped slices and bonding one slice of the plurality of airfoil-shaped slices to a tip portion of a turbine blade.

  • Patent number: 10816313
    Abstract: An angle measuring gauge incorporates four arms pivotally connected to form a quadrilateral. The arms are connected to a guide bar that attaches to the quadrilateral along a diagonal and forms an axis of symmetry. A first corner of the quadrilateral is pivotally attached to the guide bar and the opposite corner of the quadrilateral is pivotally connected and is slidable along the guide bar to adjust the angles of the quadrilateral. In practice, the first corner of the quadrilateral is adjusted to conform to a desired angle, and the guide bar bisects the angle formed by the first corner and can be used to either ride in a miter slot of a cutting tool, or adjust a miter gauge of a cutting tool to cut accurate miters.
