Abstract: A method and apparatus for removing burrs from inside slotted metal liners exposes the burrs to a high-intensity gas flame that effectively oxidizes or incinerates the burrs, without inducing undesirable temperature levels in the parent metal of the slotted liner. This is accomplished using a torch head assembly having multiple gas torch nozzles disposed radially around the circumferential perimeter of the torch head, such that when the torch head is passed through the interior of a slotted liner, the flames are directed toward the interior surface of the liner. Auxiliary oxygen is introduced at the nozzle outlets, resulting in a large increase in flame velocity and intensity and, in turn, an increase in the flame temperature. The auxiliary oxygen may be introduced through annular passages surrounding the nozzles, such that the auxiliary oxygen effectively forms a cylindrical curtain surrounding the flame at each nozzle.

Abstract: The invention is a remotely controlled internal pipe cutting device primarily used for cutting pipes where the outside of the pipe is inaccessible at the line where the cut is to be made. The device includes an axial ram within a rotational cylinder which is enclosed in a housing. The housing is adapted for attachment to an open end of the pipe and for supporting the ram and cylinder in cantilever fashion within the pipe. A radially movable cutter, preferably a plasma arc torch, is attached to the distal end of the ram. A drive mechanism, containing motors and mechanical hardware for operating the ram and cylinder, is attached to the proximal end of the housing. The ram and cylinder provide for moving the cutter axially and circumferentially, and a cable assembly attached to a remote motor provide for the movement of the cutter radially, within the pipe. The control system can be adjusted and operated remotely to control the position and movement of the cutter to obtain the desired cut.

Abstract: The invention relates to an apparatus for making divergent cuts chamfered relative to a cutting surface, e.g. welding chamfers, by means of torch cutting particularly in the internal cutting of cylindrical sheets, such as pipes. The apparatus comprises a torch (8) mounted on a fastening arm (2) at the end of a carrier arm (1), said carrier arm (1) being axially movable and rotatable around its axis. The fastening arm (2) at the end of carrier arm (1) is fitted with a transverse support arc (3), which carries an element (4) movable along an arcuate path and fitted with a longitudinal support arc (5), the latter carrying a mounting plate (6) for torch (8), the plate being movable along an arcuate path. The radii of the arcuate paths of support arcs (3, 5) are equal and their centers are equally far from the center line of carrier arm (1) at an axial distance from each other.

Abstract: This invention relates to a pipe cutting apparatus for cutting large diameter pipe. The apparatus is provided with a cutting means which can be angled for cutting miters. The cutting means can be a torch. The apparatus has a flexible drive mechanism which adjusts for variations in cutting angle. Torque is communicated to the cutting means by a motor via clutch means.

Abstract: A tool for removing cruciforms from an ice basket having an elongated, generally cylindrical and vertically oriented sidewall, the interior of which is accessible from the upper end thereof. The tool is lowered into the ice basket from the open, upper end thereof in axial alignment with the ice basket. Clamping means disposed at the lower end of the tool are aligned with a cruciform. Remote control means are operable from the exterior of the ice basket to actuate the clamping means for securely clamping the cruciform, for igniting a cutting torch assembly, and for operating a linear actuator to move the cutting torch assembly downwardly in translation, the torches of the cutting torch assembly cutting the cruciform from the ice basket. The cruciform remains clamped, and is withdrawn with the tool from the ice basket.

Abstract: An apparatus for internally removing a raised weld bead of a longitudinal seam welded tube having an elongate mandrel support body. A cutting tool is mounted on the support body adjacent one of its ends and projects outwardly from one surface on the body. A pivot roll and a stabilizing roll are mounted in the support body in spaced relation in the elongate direction of the body and project outwardly from the same surface as the cutting tool. A resiliently mounted carriage roll disposed between the pivot roll and the stabilizing roll which projects outwardly from the surface of the support body opposite the one surface. A tilting roll remotely disposed from the cutting tool and moveable in either vertical direction by cams to effect pivotal movement of the support body about the pivot roll, and advance and retract the cutting tool with respect to the internal weld bead.

Abstract: A strip made up of a linear series of rigid links hinged together. Magnets are mounted on certain links, at spaced points, for holding the strip on the object to be cut by a torch. Spacers are located on the links on which the magnets are not mounted, holding those links in spaced relation from the object, even with the other links. All the links together define straight lines of their side edges.

Abstract: A method and apparatus for cutting a series of patterns spaced along the length of a tubular member (e.g. drill collar). A cutting torch is positioned and manuevered within the bore of the pipe so that all cutting is done in an inside-to-outside direction. All slag formed by the cutting action is blown away from the pipe and does not collect within the pipe bore as in previous cutting operations of this type. Further, since there is no cross-wash of the torch, there is no substantially no heat buildup in the pipe during cutting which allows proper preheating of the pipe thereby alleviating cold cuts in the pattern.

Abstract: A steering apparatus for an autogenous cutting torch for cutting holes of desired shape in flat or curved sheet walls, such as in the wall of a pipe. The steering apparatus comprises a holder arm for an autogenous cutting torch and means for guiding the holder arm in a manner that the autogenous cutting torch can be run along a certain desired orbit or path. A problem with the prior art steering equipment is the limited scope of application, e.g. to the cutting of flat sheets only. In order to expand the scope of application to also cover curved surfaces as well as combinations of flat and curved surfaces, the holder arm is designed as a long rod (4), arranged to be axially displaceable on a slide guide (7).

Abstract: An apparatus is disclosed for re-claiming used or damaged tube turns and rendering them equivalent to new tube turns with correctly oriented openings. A salvaged tube turn is temporarily fixed to a platform in a position such that the longitudinal axis of one of tube turn ends is approximately perpendicular to the plane of an adjacent circular track. The platform is moved so that the opening of the tube turn end is near the circular track. The circular track is then accurately centered with respect to the opening by use of a spider or the like which is temporarily fixed to the center of the track. Either the spider (and track) or the tube turn is moved so that the spider engages the interior of the opening.

Abstract: A device comprises a gas cutter in the form of an annular combustion chamber (10) provided with injectors and manifolds for delivery of oxidant and fuel into the combustion chamber (10) and an annular nozzle (9) adapted to cut an escape hatch out of the intact area of an aircraft hull. Mounted centrally in the combustion chamber is a punching-and-gripping means (8) fired into the wall to be cut for securing a gas cutter (6) thereto. This gas cutter together with oxidant and fuel bottles may be conveniently mounted between external and internal skins of an aircraft to serve as means for performing an independent autonomous rescue operation with the result that in the course of several seconds escape hatches may be cut in an aircraft hull with the maximum safety and dependability, without waiting for arrival of rescue parties at a crash scene.
