Abstract: Linear wellhead connection systems and related methods of pumping fluid into a plurality of wellheads. The linear wellhead connection system uses linear movement of an inlet conduit to transition between multiple discharge conduits that are connected to different wellheads to pump pressurized fluid from a manifold to the different wellheads. The inlet conduit is moveable in a linear direction along a track system relative to the discharge conduits.

Abstract: A heat exchanger apparatus has a heating stage with a product side and a hot water side and a cooling stage with a product side and a coolant side, and also regeneration stages with treated and un-treated product sides. There are valves including a cooling stage outlet valve, and pressure sensors, and pumps for pumping process liquid through the product sides. A PLC controller is programmed to operate the pumps with outlet valves closed to pressurize the product sides of the stages at a pressure dynamically maintained by control of the pumps in response to sensed pressure. The valves are controlled to firstly vent the heating and cooling sides of the heating and cooling stages with the product sides pressurized, and then in a second phase to vent the downstream (treated) product sides of regeneration stages. Also, an in-line holding time test is performed by monitoring time for step rises in temperature to reach a temperature sensor and the outlet end of a holding tube.

Abstract: A testing apparatus is for a tank with a jacket having an internal wall shared with the tank and an external wall. The testing apparatus has an automated controller to perform tests even during use of the tanks in a production environment. There is supply system for delivering liquid at pressure above atmospheric to the jacket. The controller detects when the tank is filled to a level above the tank jacket height to create a higher pressure in the tank than is in the jacket. The controller monitors a parameter of the jacket to detect if there is a leak from the tank into the jacket. The parameter may be jacket pressure, arising after sealing the jacket, of flow via a venting valve as detected by a flow meter. A second test can be carried out irrespective of the level in the tank, be pressurising the jacket and monitoring it for a drop in pressure.

Abstract: The disclosure relates to a method of conducting a coiled tubing operation. In one implementation, a method includes forming a tubing string, the tubing string having an outer surface. The method also includes applying a coating to an application portion of the outer surface of the tubing string. The application portion includes a portion of the tubing string that will be disposed in a horizontal section of a wellbore, and the coating has a surface energy lower than a surface energy of the outer surface of the tubing string to thereby reduce friction between the tubing string and a casing disposed in the horizontal section of the wellbore as the tubing string is lowered into the wellbore.

Abstract: A deconstructable coiled tubing spool is disclosed and includes one or more flange segments, and a core comprising a flange portion that is adapted to couple and decouple from each of the one or more flange segments, wherein the core remains intact when the one or more flange segments are decoupled from the flange portion. One or more of the deconstructable coiled tubing spools can be deconstructed and stored in a standard shipping container for shipment.

Abstract: The present invention describes an apparatus for nanolithography and a process for thermally controlling the deposition of a solid organic “ink” from the tip of an atomic force microscope to a substrate. The invention may be used to turn deposition of the ink to the substrate on or off by either raising its temperature above or lowing its temperature below the ink's melting temperature. This process may be useful as it allows ink deposition to be turned on and off and the deposition rate to change without the tip breaking contact with the substrate. The same tip can then be used for imaging purposes without fear of contamination. This invention can allow ink to be deposited in a vacuum enclosure, and can also allow for greater spatial resolution as the inks used have lower surface mobilities once cooled than those used in other nanolithography methods.

Abstract: A gain control and signal conversion stage in a data converter for a color video CRT display system is disclosed. The disclosed circuit includes capacitors for supplying current at a selected output voltage level, voltage followers for charging the capacitors, and modulators for forming low-level analog color signals for control of video amplifiers in a color CRT display. Digital control of video brightness or contrast and precise color tracking are features which are discussed.
