The protective cap (1) includes resilient ridges (8) extending inwardly from an insert member (2), and/or a chip at least partly within the cap.

A wire harness including: an electrical wire; and an exterior pipe through which the electrical wire is inserted, wherein the exterior pipe is provided with a plurality of discharge holes configured to outwardly discharge foreign matter that has entered between the exterior pipe and the electrical wire. An exterior pipe through which an electrical wire is to be inserted, the exterior pipe including: a body with a plurality of discharge holes configured to outwardly discharge foreign matter that has entered between the body and the electrical wire, wherein the plurality of discharge holes are provided in an aligned arrangement.

A thread protector for use with sucker rods and other downhole tools is pushable onto an end of the sucker rod for secure retention. The thread protector is optionally squeezed and rotated for release from the end of the sucker rod. Included on the protector is a sleeve having a closed end and an opposite open end for receiving and pushably engaging with the end of the sucker rod. The sleeve has one or more first regions around a circumference of the sleeve having reduced diameter for engagement with one or more regions of the end of the sucker rod and one or more second regions around the circumference of the sleeve having enlarged diameter. Application of pressure to the one or more second regions of the sleeve causes disengagement of the one or more first regions from the end of the sucker rod for removal of the thread protector.

The invention concerns an arrangement for the guidance of flexible lines that run from a crane arm (3) through its end section (2) to a tool (4), that is suspended at the crane arm through a link arrangement (5) and a frame that is a component of a rotator (6) for rotation around a vertical first axis (A) and in a cardan manner around second (B) and third (C) horizontal axes, For the discrete and protected passage of hoses, it comprises a first holder (35) in an opening (3A) of the end section (2), a second holder (38) in a central region of the rotator (6), a first hose package (1A-1D) that extends between the said first (35) and second holders (38), a penetration (26) in a central region of the rotator (6) and permitting hydraulic fluid to pass through the rotator (6) and onwards to a lower part (18) of the same at least one of the said second (B) and third (C) horizontal axes comprises an “open joint”.

This disclosure relates to an indicator cap for a pipe penetration. In one aspect, the indicator cap comprises a cap body, wherein the cap body comprises an engagement portion for engaging the indicator cap with the pipe, and a capping portion connected to the engagement portion for covering an open end of the pipe, and wherein a surface of the capping portion supports a means for aiding location of the indicator cap and thus the pipe, wherein the means for aiding location is adapted so as to not impede screeding thereover, and to indicate the position of the cap and thus the pipe post screeding.

A robotic vehicle for moving above ground while fabricating a subsurface polymer layer to protect an underground structure is provided. The robotic vehicle includes: a body; a rotational member that contacts the ground and moves the body over the ground; a ripper assembly having a proximal end that moves with the body, and a distal end that moves underground at a fabrication depth in response to the movement of the proximal end while fabricating the polymer layer; a ground penetrating radar (GPR) that locates and measures a depth of the underground structure below the ground; and a computerized control system that controls the rotational member, the distal end of the ripper assembly, and the GPR to move the body over the located underground structure while tracking the location of the underground structure and fabricating the polymer layer at the fabrication depth and above the measured depth of the underground structure.

A containment sleeve for use with a pressurized piping system including a pliable fabric sheet having first and second opposing longitudinal edges, first and second opposing transverse edges, and first and second opposing major surfaces respectively defining an interior and exterior surfaces. At least one pleat extends between the first and second transverse edges, the pleat being in a normally closed position to define the interior surface with a first surface area. The sheet of pliable fabric to secure about a portion of a pressurized piping system with the interior major surface facing the pipe so as to form a sleeve having an initial interior volume there about. In response to a rupture of the pressurized piping system within the interior volume, the pleat to expand to an open position to expand the interior surface to a second surface area to increase the interior volume from the initial volume.

A quick coupling assembly includes a first coupling element (10) and a second coupling element (50) that is inserted into the first coupling element. The first coupling element has a coupling body (12) and a valve (20), which define a volume displacement passage. When the second coupling element (50) is inserted, the second coupling element mechanically acts on the valve (20) to expel contaminants from the quick coupling assembly via the volume displacement passage. The valve includes a poppet (22) and a biasing spring (24), and the volume displacement passage includes a leak path (66) defined between the coupling body and the poppet. The poppet has an inward contour (68) that is spaced apart from the coupling body to define the leak path. The poppet has a widened portion (70) that provides a sealing surface when the assembly is fully coupled. The second coupling element (50) mechanically acts on the poppet (22) during insertion to expel the contaminants via the volume displacement passage.

In order to further improve a method and a device for rehabilitating a pipe section, wherein the rehabilitation device has at least one tube-shaped inliner for sealing damage to the pipe section and a heating element, in such a way that the rehabilitation may be carried out more easily, safer, and more economically, it is proposed to design the heating element as a tube-shaped and electric heating element and to arrange it essentially across an entire length of the inliner arranged within the pipe section, and to cure the inliner essentially along the entire length in one step by means of the tube-shaped electric heating element.
