Disclosed herein are a treatment apparatus and method for a waste steam generator, and an installation method of a treatment apparatus for a waste steam generator. The treatment apparatus includes a cutting part for cutting a body of a waste steam generator, a driving part for driving the cutting part, and a support frame for supporting the cutting part and the driving part, wherein the support frame is coupled to an outer peripheral surface of the body of the waste steam generator in a divided state, and the cutting part is driven and cuts the body in a state in which the support frame is coupled to the outer peripheral surface of the body. Consequently, since the treatment apparatus is easily moved and installed, an installation time of the treatment apparatus may be shortened and an exposure time of a worker can be reduced.

Embodiments of the present disclosure provide surface treatment tools, methodologies, and/or treated turbomachine components. A surface treatment tool according to the present disclosure can include a lathe assembly having a lathe chuck for receiving a component thereon, wherein the lathe chuck rotates the component about a first axis of rotation, and wherein the component includes an exposed axial target surface; and a sander or burnishing tool coupled to the lathe assembly and including a sanding or burnishing surface thereon, coupled to a drive system, wherein the sanding or burnishing surface is oriented along a second axis substantially non-parallel with the first axis of rotation, such that the sanding or burnishing surface selectively contacts the target surface of the component to yield a polished target surface.

A preferred embodiment of a hand-operated flush cutting machine includes a front section with a first and a second disc shaped cutter blade which are rotary about an axis of rotation and mounted in the front end of an elongated tool carrier having the substantial shape of a flat bar. The tool carrier is mounted to a rear section of the machine. The rear section is provided with a number of components, including a motor for driving the cutter blades via a power transmission as well as handles and a control for operating the machine. The first, right hand side cutter blade has a first side, which does not face the second cutter blade. The first side defines a first plane which does not intersect any component in the front or rear sections.

An apparatus for cutting a curved wall of a structure, of the present invention, may comprise; a guide rail mounted on a curved wall of a structure; a chain mounted on the guide rail; a support plate supported by the guide rail so as to be movable by means of a plurality of rollers; a body case coupled to the support plate; a sprocket mounted at the body case so as to rotate while engaged with the chain; a driving motor mounted in the body case so as to rotate the sprocket; a cutting blade rotatably mounted at the front of the body case; and cutting motor mounted in the body case so as to rotate the cutting blade.

An apparatus for supporting a saw assembly for cutting a workpiece, comprising: a main frame supporting a translatable frame translatable longitudinally for releasably supporting the saw assembly such that at least a portion of a saw extends below the translatable frame into an interior space; a first support positioned for supporting at least a portion of a first edge of the workpiece; and a second support generally parallel to the first support for supporting at least a portion of a second edge of the workpiece and moveable laterally between (i) a retracted position and (ii) a plurality of extended positions, each extended position between the retracted position and the first support. The saw when activated and translated longitudinally over the interior space cuts the workpiece while the at least the portions of the first and second edges of the workpiece are at rest upon the first and second supports.

A method of medical treatment for transecting a ring trapped on an appendage of a patient is described. The method of medical treatment includes inserting a safety guard between the appendage and a portion of the ring, activating a blade motor to rotate a rotary blade aligned with the safety guard, sensing status readings, and transecting the portion of the ring including automatically directing a safety guard actuator to move the safety guard, based at least in part on the status readings, toward the rotary blade thereby urging the ring into contact with the rotary blade.

A tool assembly is provided with an integrated support fixture and assemblies for orienting the tool at different angles relative to a workpiece. A guide rail assembly is provided that defines a travel path for the tool slidably supported thereon. The support fixture is configured to support the tool assembly on a workpiece so that gravity can assist movement of the tool across the workpiece. The guide rail assembly is mounted on a miter plate that can be oriented at different miter angles relative to the support fixture. The tool may be supported on the guide rail assembly to permit pivoting of the tool perpendicular to the miter angle. Another assembly may be provided that permits pivoting of the guided rail assembly at an orthogonal angle.

A flange bolt cutter for separating two connected flanges. The flange bolt cutter contains a circular saw blade connected to an flange mount which can be vertically adjusted relative to the flange mount and/or includes two arms which can be pivotally adjusted relative to each other.
