  • Patent number: 8534965
    Abstract: A tool is provided for use in at least one of drilling, tapping, back spot facing and counter-boring at least one hole. The tool includes a servo motor cutting device and a gearbox. The servo motor cutting device and gearbox rotate a cutting tool to create the hole. A drill unit skid is adapted to engage a hook fit slot in the case of the dynamoelectric machine and supports the servo motor drill and gearbox.

  • Patent number: 8157620
    Abstract: A system and method for cleaning receiver slots with hook-fits for stator blade ring segments. A first cleaning tool with an abrasive coating and sideward projection in the shape of the hook is slid through the slot using the hook-fit as a guide. A second cleaning tool with an abrasive coating and a formed/machined hook-fit used as a guide while cleaning the receiver slots as it is pushed through the receiver slots. The tools remove trash, oil rust/oxidation, and other foreign materials from receiving slot. Both tools may attach to a metal rod with two knuckles as part of the handle that connects to and uses the hook-fit as a guide enabling the operator to reach deep into the radius of the compressor case receiver slots and hook-fits located adjacent to and beneath the rotor and rotor blades so that the hook-fit and receiver slot can be thoroughly cleaned.
