Abstract: Method for making a remote controlled sub sea pipe connection between two pipe ends which may be relatively misaligned on a sea bottom comprising, providing a pair of mating coupling halves having misalignment capability for connecting together the pipe ends; lowering a remote controlled vehicle towards the pipe ends; installing a pipe coupling half onto each pipe end, and connecting the pipe coupling halves together and to the respective pipe ends by remotely operating the vehicle from the sea surface to thereby effect the pipe connection.

Abstract: A compact apparatus for crimping a fitting onto an elongated member is provided which has a cylindrical housing, a tubular piston in the housing providing a central passageway to receive the elongated member and a fitting, a plurality of crimping dies moving radially together and apart which are actuated by the tubular piston, fluid means for moving the tubular piston longitudinally in a forward direction and springs for retracting it, and mounting means for the cylindrical housing. The apparatus contains an improved housing and piston structure, means for positioning the elongated member and fitting between the crimping dies, and means to automatically stop the longitudinal movement of the piston at a predetermined position.

Abstract: Apparatus comprising a first frame having first pipe holders for gripping a large-diameter pipe and a second frame having second pipe holders for gripping a small-diameter pipe. The first frame and the second frame are movable relative to each other to insert the small-diameter pipe into the large-diameter pipe and/or pulling the former out of the latter.

Abstract: A pipe joint make up tool for joining pipe members together including pipes and fittings and caps in which gripper half collars having a tapered rail along each facing edge are placed around a pipe and wedging clamps having complementary flanges are thereby engaged with the rails of the collars on opposite sides of the pipe. Each collar has an internal gripping surface of flexible material. The gripper collars are each provided with a hydraulic cylinder connected to a common hand pump or to other power means. Cables or chains are located diametrically opposite each other and connected to the piston of each hydraulic cylinder on the first pipe and to wedging clamps assembled on the gripper half collar disposed around the second pipe. As force is applied by the hydraulic cylinders the wedging action as the pipes are pulled together sockets one pipe into the other at the joint between them. A gauge in the hydraulic system is used as a force indicator.

Abstract: A tool for inserting a plastic pipe in a substantially axial direction into a stab-type coupling joint fitting or the like without damaging the exterior of the plastic pipe. The coupling joint fitting may be of the type having means therein for gripping the plastic pipe upon insertion of the same therein and also of the type wherein insertion of the plastic pipe activates closure means in the fitting to open the same and provide service. The means for attaching the tool to the fitting and to the plastic pipe are detachable from the tool whereby other means may be substituted therefor depending upon the sizes of the fitting and the plastic pipe upon which the tool is to be used. The actuating means for moving the attaching means for the pipe toward and away from the attachment means for the fitting is screw operated to provide ease of operation of the tool with a lever system providing a large mechanical advantage.

Abstract: Apparatus for crimping a fitting onto a hose or the like, including a ram with a slideable piston for moving a set of crimping dies together, wherein the piston has a central passageway extending along its entire length so that a hose can extend through the back end of the machine.

Abstract: A tube coupling joint comprising a tube having an enlarged end, a body having a bore to receive the tube end and having a cam surface leading to the bore, a sleeve having an inner end with a transverse shoulder contracted to a diameter less than the tube diameter with the sleeve shoulder embedded within the tube adjacent the expanded portion of the tube, and a nut holding the sleeve into engagement with the cam surface whereby the cam surface maintains the sleeve shoulder in its embedded position.

Abstract: An improved tool for applying radial stresses to a tubular splicer to deform the splicer radially inwards about adjacent ends of a pair of aligned reinforcing bars to lock the splicer to the bar ends. A support mechanism is also provided for attachment to a first of the reinforcing bars to support the tool while the radial stresses are created.

Abstract: The irrigation apparatus includes a quick-connect, self-piercing drip emitter insertable in a plastic pipe to effect a controlled, localized trickle of irrigating water. The apparatus is usable either above the surface of the ground or below the surface and may include a protective wrap to keep dirt from clogging the emitter and to spread the flow of irrigating water over a larger area.

Abstract: An underground joint between sewer pipe and reinforced concrete manhole riser is tightly sealed, and resistant to breakage caused by settling or frost heaving by a tapered, elastomeric, tubular connector boot, capable of flexing and yielding under lateral shift. A smooth faced hole is core drilled in the riser wall. The large end of the boot is expanded radially, by an expandable metal band, to a permanently enlarged diameter and internally clamped within the hole which compresses the material of the boot against the hole surface at 1000 psi, or more. The band is expanded and clamped in a direction normal to the central longitudinal axis of the sleeve by hydraulic jack means. The pipe end is inserted in the boot, up to the inside wall of the manhole, but is yieldable in any direction without leakage or breakage.

Abstract: An improved method and apparatus for coupling together conduit sections to form a pipeline while submerged in a fluid medium. During the operation of laying the pipeline while submerged in a fluid meduim, such as the ocean, adjacent pipe sections to be joined are subjected to a reduction in internal fluid pressure with a pump or the like so that during the joining operation, the pressure inside the adjacent pipe sections is lower than the exterior fluid pressure causing the pipes to readily come together and seat properly.

Abstract: An apparatus for joining the free end of a first pipe to a coupling collar secured to the end of a second pipe includes a longitudinally extending member adapted to engage the coupling collar while supported by the second pipe, and a flexibly extending member secured to the lateral member. With the pipe ends adjacent, the flexibly extending member is wrapped spirally about the first pipe and secured thereto. A lever member adapted to engage the flexibly extending member is then placed on the longitudinally extending member, and operated to tension and pull the flexibly extending member, which draws the end of the first pipe into the coupling while also rotating the first pipe.
