Abstract: A process for repairing a metallic shroud of a gas turbine blade includes a step of removing a portion of an anti-wear layer to a removal depth that is greater than a depth of wear of the anti-wear layer. Further, the process includes a step of leaving a trace of the anti-wear layer to subsist, wherein the trace of the anti-wear layer extends at least in a re-entrant zone of the Z profile of the blade. The process also includes a step of depositing a new layer of anti-wear material on the trace of the anti-wear layer.

Abstract: The present invention is an apparatus and method for repairing a collapsed underground duct for a fiber cable. A head is inserted into the duct until the collapsed section is sensed. Power, such as hydraulic or pneumatic pressure of electric potential, is applied to the head, actuating an expansion member that engages the duct wall and applies a force to it, forcing it to a non-collapsed state. The head may be fed through the non-collapsed duct by applying air pressure behind it, forcing through the duct until it encounters the collapsed section.

Abstract: A semi-automatic method for reconditioning an articulated connector while it is still mounted to the end structure of a rail car is disclosed. The female connector is mounted to a fixture and subsequently appropriately aligned. Weld metal is automatically applied to the worn portion of the female connector while attached to the aligned fixture. The excess weld metal is then automatically machined away so that the connector falls within the required dimensions. A measurement of the weld area can again be taken to ensure that the specified dimensions have been achieved.

Abstract: A molding die has through holes composed of feed holes and slit grooves for producing honeycomb structure bodies. The slit groove is formed in at least a part of each through hole. In a method of inspecting the molding die, a light is irradiated into the feed holes side to pass through the through holes. A camera is disposed at the slit groove formation side of the molding die to photograph the amount of light output from the slit groove side. A difference in intensity of the amount of light output from the slit grooves is calculated in order to detect at least the presence of a defective slit groove having an abnormal part. In another method of repairing the defective slit groove, a modifier made of abrasive grains and clay mother material is forcedly provided into the defective slit groove in order to repair or remove the abnormal part.

Abstract: A method of mitigating the effects of damage to a metallic, ceramic, or intermetallic article through the introduction of compressive residual stresses taking into account the effects of the stress concentration factor associated with a damage notch under compression. A layer of compressive residual stress is introduced into the surface of the article to a depth greater than the depth to which damage, such as corrosion pitting or foreign object damage, extends into the surface of the part. The induced compressive residual stresses improve the fatigue and stress corrosion cracking performance of the article while the stress concentrating properties associated with a damage notch under compression prevents cracks from initiating from within the notch under applied loads.

Abstract: A method for repairing a turbine engine component comprises the steps of providing a turbine engine component formed from a nickel-based superalloy, removing any defects from the turbine engine component, the removing step comprising subjecting the turbine engine component to a solutioning heat treatment using a heating rate in the range of from 29 degrees Fahrenheit/minute to approximately 40 degrees Fahrenheit/minute as the component passes through a temperature in the range of from 1100 degrees Fahrenheit to 1600 degrees Fahrenheit, and welding the turbine engine component to effect the repair. A deliberately slow post-solution treatment cooling rate is used to substantially prevent weld cracks.

Abstract: An apparatus and method for reforming deformed drums. Deformed drums are placed over an apparatus that expand a series of arms as a user exerts a force generally downward and outward along a sliding axis of a central mast.

The apparatus is portable enough such that it can easily be mounted to a movable platform, for example, a construction vehicle with a typical square receiver trailer hitch.

Abstract: The apparatus includes a track mounted in the inlet of a compressor. A manipulator is mounted for movement about the track and carries three modules, the last of which mounts a tool head for movement in a Cartesian coordinate system and about the track. A measuring head measures the location of the airfoil surface. An abrading tool mounted on the third module removes surface material from the airfoil. Subsequently, a shot-peening device, either a flapper with embedded shot or free shot is impacted against the abraded surface to strengthen the surface. Final inspection is performed by a light and camera head mounted on the third module.

Abstract: A method for reconditioning an articulated connector while it is still mounted to the end structure of a rail car is disclosed. The connector is measured to find areas and amounts of wear on portions of the connector. The measurements are taken relative to a reference portion of the connector. Weld metal is then applied to the worn portion of the connector. The excess weld metal is manually or automatically machined away so that the connector falls within the required dimensions. A measurement of the weld area is again taken to ensure that the specified dimensions have been achieved. Apparatuses for measuring wear and specified dimensions and aiding in the method of reconditioning the connectors are also disclosed.

Abstract: The invention relates to a method of assembling a structure, particularly those structures requiring very tight tolerances. The structure may be assembled by positioning shim material on at least part of a sub-structure, curing the shim material in situ, machining the cured shim material to a desired thickness, and then assembling outer layer parts to the sub-structure such that the shim material is situated between the substructure and the outer parts. The shim material may be machined to different thicknesses at different locations on the sub-structure, so that, when assembled, the outer layer parts together conform to a predetermined profile. This is especially advantageous in the manufacture of airframes, where the outer layer panels must provide a smooth surface to avoid unwanted aerodynamic effects.

Abstract: A hand tool that has a pliers-like body and a special head. The head has a pair of parallel teeth that fit onto the grooves of a zipper guide.

Such a tool can be used on all types of zippers, such as those found on tents, clothing, tote bags, luggage and many other things.

Abstract: An apparatus and method for in-situ milling includes a support and a pair of spaced apart rails attached to the support. The support and rails are mounted between a pair of opposed mill housing wear plate surfaces. A milling assembly is reversibly mounted on the rails in either of a first orientation and a second orientation. In the first orientation, the milling assembly mills one of the wear plate surfaces. The milling assembly is reverse mounted on the rails to the second orientation for milling the other of the wear plate surfaces. This permits the support and the rails to remain in one position between the wear plate surfaces requiring only the milling assembly to be moved to accomplish milling of each of the wear plate surfaces.

Abstract: A stuck locking pin is removed from a turbine rotor by forming an aperture in the locking pin. The diameter of the aperture is less than the diameter of the locking pin, such that a thin shell portion remains in the locking pin receiving slot of the rotor. The locking pin then can be easily removed by any suitable means, such as by driving a high-strength metal rod into the aperture. The driving force stretches the thin shell portion, which easily separates from the rotor.

Abstract: A method of refurbishing a damaged section of the outer rim bead of an automotive wheel. The method comprises the initial step of contouring the outer rim bead via a first grinding process to create a feathered transition between the damaged section and the remainder of the outer rim bead. Thereafter, the damaged section is profiled via a second grinding process to generally conform the shape of the damaged section to the remainder of the outer rim bead. Finally, the damaged section is painted. The refurbishment steps may be completed on-site without removing the wheel from the vehicle and without removing the tire from the wheel.
