摘要： A method of cleaning a tubular with a cleaning tool that includes the steps of disposing the cleaning tool in the tubular, the cleaning tool having a main body with a first end, a second end, an inlet, an outlet, and a propulsion relief assembly disposed proximate to the second end. The method further includes the steps of sufficiently pressurizing fluid behind the tubular to propel the cleaning tool along the tubular, and increasing the pressure of the fluid to actuate the propulsion relief assembly, whereby fluid is jetted out the outlet and out of the propulsion relief assembly.

摘要： A carrier assembly having at least one sealing cup, a fluid bypass and adjustable wash nozzles, as well as a spear assembly having a central through bore, are attached to the distal end of a length of continuous tubing and inserted in to the flow bore of a pipeline. Fluid is pumped through the annular space between the carrier assembly and the pipeline, providing motive force for advancing the carrier assembly within the pipeline. Fluid can bypass the carrier assembly, enter the central bore of the spear assembly, and return to the surface through the central bore of the continuous tubing. A stuck pig or other obstruction is speared, and thereafter retrieved from the pipeline on the continuous tubing.

摘要： A method and apparatus have been developed which inserts and withdraws tubing from pipes without bending or kinking the tubing. Beneficially, the method and apparatus may be employed to insert and withdraw tubing to depths greater than ever possible before. The method involves using a thruster pig to provide force to inject the tubing. The thruster pig uses a pressure differential to urge the tubing into and out of the pipe. Advantageously, check valves or relief valves allow fluid to be pumped down the tubing and out the front of the thruster pig, and then to flow back through the valves and up the annulus between the pipe and the tubing.

摘要： A convertible gurney (10) has an outer fixed support frame (12) which includes a pair of side frames (16) connected by lower horizontal cross frame members (30). An inner frame (14) includes a base (84) and hinged segments (42, 46 and 48) which define rear, seat and leg segments. Inner frame (14) is positioned between the side frames (16) and removably connected thereto by four fasteners (90). A detachable manual operator (170) is mounted on a selected side frame (16) opposite a bed (36) for a patient and effects movement of the segments (42, 46, 48) between gurney and chair positions by operation of a hand crank (184). Each side frame (16) has a foldable side panel (190) which may be utilized in transfer of a patient between a bed (36) and the convertible gurney (10). A patient is first positioned on a hard transfer board (36) as shown in FIGS. 9 and 10 and moved with the transfer board (36) across the side panel (190) forming a bridge between the bed (36) and the convertible gurney (10). An embodiment shown in FIGS. 11-13 provides a pair of separate leg frames (51A, 53A) to permit individual movement of a selected leg frame (51A, 53A).

Outer support frame (12) has a pair of opposed vertical side frames (16) and a plurality of lower cross members (30) extending between the lower ends of the side frames (16). Inner movable frame (12) has a lower base (84) supported on cross members (30) of the outer frame (12), and a pair of linkages (72, 74) supported on the base (84) connected to three hinged segments (48, 52, 54) which define a rear back support segment (48), an intermediate seat support segment (52), and a front leg support segment (54). The linkages (72, 74) are operatively connected to drive nuts (106, 126) which are mounted on an externally threaded power screw (108) for movement. A patient is supported in a supine position at the uppermost position of the hinged segments (48, 52, 54) shown in FIG. 2 and is supported in a seated position at a lower position of the hinged segments (48, 52, 54) as shown in FIGS. 4 and 5. A modification is shown in FIGS. 10-13 in which manual actuation of the chair and gurney (10A) by a handle (152A) may be provided from either side of the chair and gurney (10A) as may be predetermined.
