A machine includes a tool housing defining a housing cavity; a first tool coupled to a first linear drive mechanism, the first tool linearly repositionable along an axis by the first linear drive mechanism about and between a first retracted position and an extended position, the first tool positioned within the housing cavity in the first retracted position, the first tool positioned external to the housing cavity in the extended position; and a second tool coupled to a second linear drive mechanism, the second tool linearly repositionable along the axis by the second linear drive mechanism about and between a second retracted position and a sealing position, the second tool positioned within the housing cavity in the second retracted position, the second tool positioned external to the housing cavity in the sealing position.

A method and apparatus for tapping into a pressurized multiple strings of coaxially situated tubulars for wells and/or platforms which have overturned wherein the tapping occurs underwater via a diver or remotely operated vehicle. The assembly includes a tapping tool connectable to the tubular via a saddle connection and an adjustable tapping clamp with adjustable support/locking feet, compression plate with view ports, and angularly adjustable hot tapping system, along with a drill/saw system.

A rotary tube notching apparatus is provided that is capable of operable attachment to a powered rotational drive device. The apparatus comprises a tube support assembly defining an aperture for receiving a tube and having a clamp for securing the tube against movement in relation to the aperture. A shaft assembly is provided for receiving a cutting tool, and a carriage assembly is rotatably mounted to the shaft assembly. The carriage assembly has at least one fastener for securing the shaft assembly in relation to the aperture. The shaft assembly is selectively repositionable in relation to the aperture in an offset dimension defined by linear displacement from a central axis of the aperture, in a yaw dimension defined by a plane extending along a central axis of the aperture, and in a roll dimension defined by a cross-sectional circumference of a tube received within the aperture.

A pipe machining apparatus includes a frame, a tool carrier rotatably coupled hereto and including first and second couplers at first and second coupling locations, a first machining apparatus including a first tool support and a first tool supported thereby, and a second machining apparatus including a bridge member having first and second support members at ends thereof, and a second tool supported by a second tool support on the bridge member. The first and second tools are configured to perform different machining operations. The first tool support is configured to be couplable to the first coupler when the first machining apparatus is used. The first support member is configured to be interchangeably couplable to the first coupler and the second support member is configured to be couplable to the second coupler when the second machining apparatus is used.

A tool for removing a coating from an end of a coated conduit comprising a metallic conduit having an outer diameter and a polymeric material applied over the outer diameter thereof is provided. The tool comprises: a guide member having an outer diameter sized to fit within an internal diameter of the metallic conduit; and a cylindrical cutting member having a substantially closed first end rotatably connected to an arbor, a substantially open second end, and a plurality of teeth elements. The cylindrical cutting member has an inner diameter that is substantially equal to the outer diameter of the metallic conduit such that when the cylindrical cutting member is rotated, the teeth elements remove the polymeric material from the outer diameter of the metallic conduit.

In one aspect, a pipe cutting assembly is provided and includes a first base, a second base and a cutting insert. The first base includes a first projection and a first coupling aperture defined in the first projection. The second base is separate from the first base and includes a second projection and a second coupling aperture defined in the second projection. The cutting insert includes a cutting edge and an insert aperture defined therein. The cutting insert interchangeably couples to the first base and the second base. With the cutting insert coupled to the first base, the first projection is at least partially positioned in the insert aperture, and, with the cutting insert coupled to the second base, the second projection is at least partially positioned in the insert aperture. In one aspect, a pipe machining apparatus is provided and includes this pipe cutting assembly.

A motorized drapery system having an elongated rotating drive element that has a non-circular cross-sectional shape such as square, rectangular, trapezoidal, cross shaped or any other non-circular shape that is twisted. In one arrangement the drive element is twisted in one direction along its entire length. In another arrangement the drive element is twisted in one direction in a first section and twisted in an opposite direction in a second section thereby providing a center opening/center closing drapery. A plurality of rings are positioned around the drive element including at least one driver ring that includes a feature that connects to the drive element and is configured to facilitate movement along the drive element, and a plurality of idler rings that are configured to slide along the drive element. A curtain is connected to the rings and opens and closes as the rings move along the drive element.

A machine includes a tool housing defining a housing cavity; a first tool coupled to a first linear drive mechanism, the first tool linearly repositionable along an axis by the first linear drive mechanism about and between a first retracted position and an extended position, the first tool positioned within the housing cavity in the first retracted position, the first tool positioned external to the housing cavity in the extended position; and a second tool coupled to a second linear drive mechanism, the second tool linearly repositionable along the axis by the second linear drive mechanism about and between a second retracted position and a sealing position, the second tool positioned within the housing cavity in the second retracted position, the second tool positioned external to the housing cavity in the sealing position.
