20130247377 | PROCESS OF REPAIRING A COMPONENT, A REPAIR TOOL FOR A COMPONENT, AND A COMPONENT - A process of repairing a component, a repair tool for a component, and a component are disclosed. The process includes removing material from a region of the component. The removing forms a through-cut in the component, forms a partial-frustoconical geometry in the component, forms a substantially partial-frustoconical geometry in the component, forms a partial-spherical geometry in the component, forms a substantially partial-spherical geometry in the component, forms a partial-elliptical geometry in the component, forms a substantially partial-elliptical geometry in the component, forms a partial-cylindrical geometry in the component, forms a substantially partial-cylindrical geometry in the component, is in a direction substantially perpendicular to a surface of the component, is in a direction substantially inclined with respect to the surface of the component, or a combination thereof. The repair tool includes a securing mechanism and a cutting portion for removing a region. The component includes a region formed by removing material. | 09-26-2013 |

20140245752 | SYSTEM AND METHOD FOR ATTACHING A ROTATING BLADE IN A TURBINE - A system for attaching a rotating blade in a turbine includes a bush having an axial slot and a radial slot that intersects with the axial slot. A radial retention member fits within the radial slot, and an axial retention member fits within the axial slot and engages with the radial retention member. A method for attaching a rotating blade in a turbine includes inserting a bush into an axial passage in a rotor wheel and inserting a radial retention member into a radial passage in the rotor wheel and through at least a portion of the bush. The method further includes inserting the rotating blade in a slot in the rotor wheel, inserting the radial retention member into a retention slot in the rotating blade, and inserting an axial retention member into the bush. | 09-04-2014 |
