摘要:
A method for repairing a turbine engine component is provided. The method broadly comprises the steps of providing a turbine engine component having an airfoil portion, applying a coating to the airfoil portion, and restoring a tip portion, a chord, and surfaces of the airfoil portion to original dimensions in a single operation. A system for repairing the turbine engine component is also described.

The invention is related to an improved method of removing tubes from tubes sheets. The improved method softens and elongates a tube circumferentially surround by tube sheet, wherein the softening and elongating steps allow for quick and easy removal of the tube from the tube sheet without damaging the tube sheet or tube seats.

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.

A process and apparatus for preparing an MCM for hat removal where the hat includes a piston thermally coupled to a corresponding chip. The apparatus includes a heater positioned to reflow a joint between the piston and a base of the hat; and a retractor for biasing the piston away from the corresponding chip. Implementation of the apparatus and process prevent a piston, as it moves across the top of a corresponding chip during mechanical shear to remove the hat, to impact chip(s) and surrounding components. In addition, since piston(s) are retracted, the likelihood of piston impact with or cracking of a chip is reduced. In addition, cutting into a corresponding chip having a tilted back surface is prevented. The need to replace chips and other electronic components when making other repairs may, therefore, be greatly reduced.

A roll for smoothing a web, a process for making the roll and a process of repairing the roll. The roll includes a roll core having an outer surface. A covering layer is disposed on the outer surface of the roll core. The covering layer has an inner surface and an outer surface. The covering layer includes an elastic matrix material. The elastic matrix material includes a mixture of at least one thermosetting plastic and at least one thermoplastic. The process of making includes providing a roll core having an outer surface, forming an elastic covering layer including at least one thermosetting plastic and at least one thermoplastic, and applying the covering layer to the outer surface of the roll core. The process of repairing includes heating an elastic covering layer made from an elastic matrix material which comprises at least one thermosetting plastic and at least one thermoplastic, and allowing any markings in a surface of the covering layer to be filled.

The invention relates to an improved mattress comprising an inner spring assembly from a used mattress wherein the inner spring assembly has been stripped of its outer covering of ticking and padding material, heat treated to provide stress relief to the components of the inner spring assembly having received only partial stress relief or no stress relief when the assembly was new, and covered with new ticking and padding material. Prior to the heat treatment, the used inner spring assembly has any bent border wires and connecting wires straightened, and displaced components returned to their proper position, and any damaged components replaced with good quality new or used replacement components resulting in the same inner spring assembly structure as when the assembly was new. The resulting mattress has improved load bearing capacity compared to the original mattress when it was new.

A method and apparatus for reconditioning wood wine barrels. An open wine barrel is placed on a barrel rotator stand and positioned into a planer-cutter apparatus. Cutting parameters are set, and a horizontal screw advances the cutter into the barrel, cutting a swath the length of the barrel stave. The cutting process is repeated through the number of passes required. The barrel is dried, placed on a toasting rotator stand, and positioned under a toaster so that the toaster elements are inside the barrel. An expansion mechanism places the toaster elements adjacent the barrel interior surface, and the barrel ends are closed. After toasting, the expansion assembly is retracted and the barrel is removed. The barrel heads are run through a planer, dried, and sanded, and placed in a head toaster. The head toaster doors swing closed placing the heads adjacent oscillating firebars.

A body of shape memory metal is placed within a tubing by a running sub which transports the body to a desired location within the tubing while the shape memory metal is in its martensitic phase whereupon the shape memory metal is heated so as to regain its original shape which is tailored to its application inside the tubing.
