  • Patent number: 11391407
    Abstract: A pipe rehabilitation system and/or robot can be used inside a pipe to measure characteristics of branch conduits, install plugs into branch conduits before the pipe is lined with a liner, remove portions of plugs and liners after lining to restore fluid communication between the pipe and branch conduits, and/or install fittings into the branch conduits to connect the liner to the branch conduits. A probe can measure characteristics of a branch conduit. A tool can install plugs and/or fittings into the branch conduits. A linkage can connect a tool to a robotic tractor so that the connected elements can navigate through a main pipe. A visualization system can aid in aligning a robot with a branch conduit. Height-adjustable braces can support robotic tools in a pipe. A plug can include integrated locating features and/or movable parts that enable expanding the plug to seal with the branch conduit.

  • Patent number: 11384870
    Abstract: Helically reinforced, flexible tubing or hose is formed from continuously extruded thermoplastic material helically circumferentially wound at a wrapping station around an array of bearing-supported rods that are concurrently but individually turned and are adjustably canted relative to an imaginary center axis. The tubing or hose being formed has a continuous reinforcing rib helically wound therearound and continuously integrally connected thereto. The resulting tubing or hose may be transversely severed at intervals along its length to provide discrete lengths of hose that are annealed while axially compressed to relieve stress.

  • Patent number: 11306859
    Abstract: A hydrophobic separating plug is used to separate and inhibit mixing between a first material and a second material. The plug may be formed of a hydrophobic material or may be formed of a plurality of pigs that are a solid or semi-solid material that may be hydrophobic or may have a hydrophobic or superhydrophobic surface. The plurality of pigs may be disposed within a hydrophobic fluid and the pigs may be neutrally buoyant in the hydrophobic fluid. The hydrophobic separating plug has dimensions sufficient to substantially fill the cross-section of pipe sections in which it is located and to define a leading edge and a trailing edge such that the leading edge is in contact with a first material and the trailing edge is in contact with a second material. Advantageously, mixing between the first material and the second material is inhibited by the plug.
