| 183 | Bundle of pipes and method for parallel arrangement of pipes according to a bore and swivel method | US10470496 | 2002-01-29 | US06953305B2 | 2005-10-11 | Martin John; Klaus Rous |
| A bundle of tubes or pipes is arranged without trenches according to a fluid-assisted drilling method. A bore channel is made in a first boring step and the bore channel is widened when the bore/flushing head is removed therefrom, the bundle of tubes being drawn into the bore channel. The bundle is composed of individual tubes and flanges arranged lengthwise at a distance from and used as spacers for the tubes. A method is also described, wherein a rotational decoupling device prevents the rotational movement of the bore/flushing head produced during the removal process from being transmitted to the bundle of tubes. The bundle of tubes are supported by stabilizing devices inside the bore channel in the same spatial position as that of the tubes in relation to each other and the surrounding environment and are drawn through the bore channel. | ||||||
| 184 | Multiple sectioned duct | US11010454 | 2004-12-14 | US20050155352A1 | 2005-07-21 | Michael Agg |
| A duct comprising an inner casing spaced apart from an outer casing and which also comprises a number of interfaced duct sections must be assembled in such a way to prevent relative redial movement between the casings and thereby inhibit buckling. The present invention is a duct which utilises abutment members which longitudinally extend from each of the inner walls across the interface of the duct sections. The abutment members are radially spaced apart in normal use but are configured such that substantially relative radial movement of the inner and outer walls is prevented when the overlapping members abut. | ||||||

| A filling body is inserted together with a loose bundle of guide tubes during installation into the passage space of a protective duct, thus enlarging the bundle diameter (which reduces the buckling risk) and making crossing of the guide tubes impossible. The guide tubes are positioned along the outside of the filling body, providing access to the guide tubes during post-installation branching. The filling body may include radially projecting spacer ribs that separate the guide tubes, thereby preventing crossing movement and helical stranding. The guide tubes are thus constrained and carried along with the filling body in alignment with the spacer ribs, so that buckling, helical stranding and three-dimensional restrictions or tangles cannot occur. | ||||||

| An elongated sleeve structure for insertion and protection of elongated items within a duct is disclosed. The sleeve structure is formed from a flexible sleeve woven from warp and fill yarns to produce opposed layers in closely spaced relation. The layers have a common seamless edge and are joined along a second edge by a knit stitch formed by interlooping of successive traverses of the fill yarn which is common to both layers. The layers are of equal width and are resiliently separable into a spaced apart relationship defining a central space which accommodates the elongated items. A pull tape is positioned between the opposed layers for drawing the elongated items through the sleeve central space once the sleeve structure is positioned within the duct. Multiple sleeve structures may be joined together in an assembly using an attachment piece allowing a plurality of sleeve structures to be pulled simultaneously. | ||||||

| 194 | Coil springs for cable support | US09056498 | 1998-04-07 | US06479752B1 | 2002-11-12 | David H. Neuroth; Charles C. Collie; Timothy W. Pinkston |
| Helically wound coil springs are wrapped around and attached at regular intervals to a cable, which is positioned within tubing. The support springs are attached to the cable to provide support to the cable. The upper section of each support spring is affixed to the cable. A remainder of each spring is formed in a long open helix facing downward when the tubing is installed in a well. The open helix portion of the spring is larger than the inside diameter of the coiled tubing. During placement into the coiled tubing, the springs elongate and decrease in diameter. When the coiled tubing is installed vertically within a well, the springs compress due to the weight of the cable and engage the inside surface of the coiled tubing with a substantial portion of their length, thereby supporting the cable. | ||||||
