A carousel for pipe products including cables and umbilicals includes a drum coupled to a carousel adapter, the carousel adapter coupled to a drive unit. The carousel adapter includes an upper base plate opposite a lower base plate, a fixed base leg coupled between the upper base plate and the lower base plate and extending radially outwardly therefrom. The carousel adapter also includes a plurality of foldable base legs coupled between the upper base plate and the lower base plate and extending radially outwardly from the upper and lower base plates. Each of the foldable base legs is disposed about a periphery of the upper and lower base plates and is rotatable about an independent axis perpendicular to the upper base plate and the lower base plate.

The magnetic tape container includes a core around which a magnetic tape is wound. The magnetic tape includes a non-magnetic support, and a magnetic layer including a ferromagnetic powder. A maximum value of a deviation of a center position of an average minimum region reference circle of a trajectory of one rotation drawn by the magnetic tape, in a case where the wound magnetic tape is drawn out from the core core is 100 μm or less for three points of the magnetic tape in a width direction.

An apparatus for the dispensing and retraction of wire or cable. The apparatus including a first and second plate, at least one shaft attached to the first plate and the second plate, a spool gear attached to the shaft, a power gear shaft attached to the first or second plate, and a power gear attached to the power gear shaft and in mesh with the spool gear, wherein when the power gear is rotated, the spool gear is rotated.

A system includes a frame and a first pair of rollers coupled to a first side of the frame. The first pair of rollers is configured to support a first end of a pipe reel. The system also includes a first cradle disposed longitudinally between the first pair of rollers and a second pair of rollers coupled to a second side of the frame. The second pair of rollers is configured to support a second end of a pipe reel. The system also includes a second cradle disposed longitudinally between the second pair of rollers, a pipe guide coupled to a third side of the frame between the first and second sides, a pipe brake coupled to the frame, and a pipe re-spooler coupled to the frame.

An apparatus for the dispensing and retraction of wire or cable. The apparatus including a first and second plate, at least one shaft attached to the first plate and the second plate, a spool gear attached to the shaft, a power gear shaft attached to the first or second plate, and a power gear attached to the power gear shaft and in mesh with the spool gear, wherein when the power gear is rotated, the spool gear is rotated.

A belt drive mechanism which can be used to pay out or draw belt to or from a belt actuated system (or belt driven system). The mechanism features a self-winding spool which can automatically wind or unwind portions of the belt as they are withdrawn from, or fed to the belt actuated system. A second rotational axle (idler shaft), with one or more sheaves (e.g., pulley's or rollers) can be rotationally coupled to a capstan via a belt, and can be utilized to drive additional mechanisms in the belt drive mechanism, such as a winding mechanism.

The magnetic tape container includes a core around which a magnetic tape is wound. The magnetic tape includes a non-magnetic support, and a magnetic layer including a ferromagnetic powder. A maximum value of a deviation of a center position of an average minimum region reference circle of a trajectory of one rotation drawn by the magnetic tape, in a case where the wound magnetic tape is drawn out from the core core is 100 μm or less for three points of the magnetic tape in a width direction.

An apparatus comprising a mobile carrier operable for transporting a reel of oilfield tubing across ground. The mobile carrier comprises a frame comprising a first frame portion, a second frame portion, and a central frame portion extending between the first and second frame portions. The first, second, and central frame portions define an opening for receiving the reel. The mobile carrier also comprises a locking mechanism operable to engage and rotate the reel within the opening, and a plurality of wheels supporting the frame on the ground. The plurality of wheels comprises a plurality of first wheels operably connected to the first frame portion and a plurality of second wheels operably connected to the second frame portion. The opening interposes the plurality of first wheels and the plurality of second wheels.

A system, device, and method for improved cable tensioning of intrinsically safe horizontal cable tensioning. A frame having a worm gear operatively associated with both a moveable shaft and a drum in such a way that in an engaged position a rotational motion applied to the worm gear is transferred to the drum, wherein the moveable shaft is movable between a disengaged position and the engaged position, rotationally locking together the drum and the worm gear so that the drum will not rotate until the rotational motion is applied to the worm gear; and a strap operatively associated with the drum. The strap associates with the cable in need of tensioning.

A strap length adjusting apparatus includes first and second stationary plates and a middle plate disposed between them. The middle plate can rotate relative to the first and second stationary plates. A biasing device is linked to first and second coupling members between the middle plate and the first plate. The biasing device can either couple the middle plate to the first plate or decouple the middle plate from the first plate. When the first and middle plates are decoupled from each other, the middle plate can rotate with respect to the first plate, and a strap partially wound about a rod that extends from the middle plate, can wind about the rod either clockwise or counterclockwise so as to continuously change a length of the strap that extends away from the rod.
