Abstract: The present invention relates to a process and an apparatus for manufacturing tubes, preferably from high-strength steels or special alloys, using the cold pilger step-by-step process, with two roll stands that can be driven, at least intermittently, back and forth in opposite directions by crank drives, said roll stands having tapering grooved rolls that are driven by rack-and-pinion systems and roll over the rolled stock with alternating directions of rotation.   The present invention is characterised in that the greater part of the shaping work is performed on the first roll stand and a lesser part is performed on the second roll, where additional smoothing is carried out; and in that in bath roll stands reducing rolling is carried out over a mandrel that is matched to the roll calibre; and in that the angular offset of the crank drive systems is so selected that the shaping zone on the first stand does not coincide in time with the shaping zone of the second stand.    The present invention also relates to a machine for carrying out the process.

Abstract: A utility knife has a blade magazine (18) removably mounted in a manually holdable housing (12) and rotatable about an axis parallel to a longitudinal axis of the housing (12). The blade magazine (18) has a series of radially and longitudinally extending circumferentially spaced blade-receiving slots (20) for separately receiving thin blades (22) having a cutting edge (24) at at least one end thereof, each slot (20) having an open front end to enable a blade (22) therein to be removed from the magazine (18) by forward movement through the front end of the slot (20). The housing (12) also carries a slidable transpo rt mechanism (42) having a manually engageable actuator (44) projecting from the housing (12) and slidable in a longitudinal direction between front and rear positions, the transport mechanism (42) also having a blade-engaging arm (112) within the housing (12). Positioning of the actuator (44) at the forward position causes a blade (22) carried by the arm (112) to project from the front end of the housing (12) in an operative position, and movement of the actuator (44) from the forward position to the rear position causes the blade (22) to be retracted from the operative position into the housing (12) and into an empty slot (20) in the magazine (18). The magazine (18) is rotatable to movethe retracted blade (22) from the arm (112) of the transport mechanism (42) and to position a new blade from another slot onto the arm for subsequent movement by the actuator to an operative position.

Abstract: This invention provides a tubing injection system that contains an injector (200) with two movable injection blocks which are remotely operable to provide a desired opening.      Each injection block contains a plurality of gripping members for holding a range of tubing sizes. The injection blocks automatically adjust to provide the required gripping force and tubing speed according to programmed instructions. A resilient tubing guidance system (40) is positioned above the injector head directs the tubing into the injector head. Sensors are provided to determine the radial force on the tubing exerted by the injector head, tubing speed, injector speed, compression of the tubing guidance member and the back tension on the reel.      A control unit (170) continually maintains the tubing speed, tension and radial pressure on the tubing within predetermined limits. The control unit also maintains the back tension on the reel. This invention also provides a tubing handling system for moving a tubing from a vessel into a subsea wellbore. A main (200) injector of the type described above is permanently attached to the wellhead. A smaller injector (190) at the vessel moves the tubing from the vessel to the underwater injector. A riser (80) between the two injectors guides the tubing into the underwater injector. A control unit (170) controls the operation of the system.

Abstract: An MWD method and apparatus for determining parameters of interest in a formation has a sensor assembly mounted on a slidable sleeve slidably coupled to a longitudinal member, such as a section of drill pipe. When the sensor assembly is held in a non-rotating position, for instance for obtaining the measurements, the longitudinal member is tree to rotate and continue drilling the borehole, wherein downhole measurements can be obtained with substantially no sensor movement or vibration. This is particularly useful in making NMR measurements due to their susceptibility to errors caused by tool vibration. In addition. the substantially non-rotating arrangement of sensors makes it possible to efficiently cam out VSPs, reverse VSPs and looking ahead of the drill bit. A clamping device is used, for instance, to hold the sensor assembly in the non-rotating position. The sensor assembly of the present invention can include any of a variety of sensors and/or transmitters for determining a plurality of parameters of interest including, for example, nuclear magnetic resonance measurements.
