Abstract: A submersible vehicle (210) includes a plurality of outlet nozzles (301, 302, 303) arranged to receive pressurised fluid from a remote supply and expel the pressurised fluid to create propulsion to manoeuvre the vehicle (210); and a plurality of valves (401) in fluid communication with the outlet nozzles (301, 302, 303) and operable to provide variable pressure and/or flow to each outlet nozzle (301, 302, 303). The outlet nozzles (301, 302, 303) are arranged about the vehicle to provide six-degrees of freedom movement and control of the submersible vehicle (210).

Abstract: The invention generally provides a dynamic back pressure regulator. In exemplary embodiments, the back pressure regulator includes an inlet, an outlet, a seat disposed between the inlet and the outlet and defining at least part of a fluid pathway, and a needle displaceable relative to the seat to form a restriction region therebetween for restricting fluid flow between the inlet and the outlet. In some embodiments, the needle can be formed of a chemically resistant ceramic or have a metal plating to provide corrosion and/or erosion resistance.

Abstract: A heater that includes a substantially flat layer of electrical resistance material having a first end and a second end, a first electrical conductor electrically connected to the first end of the substantially flat layer of electrical resistance material, a second electrical conductor electrically connected to the second end of the substantially flat layer of electrical resistance material, and an electrically insulating material surrounding the substantially flat layer of electrical resistance material and electrically insulating the first end of the substantially flat layer of electrical resistance material from the second end of the substantially flat layer of electrical resistance material. The heater may be mounted to a surface of a fluid component and used to heat the fluid component, and where the heater includes an aperture that extends through the electrically insulating material, the heater may be placed between a fluid component and a fluid substrate and used to heat both.

Abstract: A non metallic flow through electrodeless conductivity sensor is provided with a conduit having primary and secondary process fluid flow paths to form a fluid loop. At least one drive and one sense toroid surround the conduit on the fluid loop. Voltage supplied to the drive toroid induces a current in the sense toroid via the fluid loop to eliminate any need for metallic electrodes in contact with the process fluid. At least one additional drive and/or sense toroid is disposed on the fluid loop to enhance induction. Optionally one or more sense coils are disposed about the conduit outside of the fluid loop to cancel out stray electrical noise. An optional conductor disposed along the conduit detects any fluid leakage through changes in resistance thereof. A temperature detector is supported within an electrically non-conductive holder extending into the fluid flow path, so that the detector is free from physical contact with the fluid.

Abstract: In an ionic-activity sensor, an osmotic pump drives a reference-cell electrolyte to flow through an interface with the solution to be measured. This minimizes contamination of the reference cell by that solution. The driving force results from expansion of an electrolytic-agent reservoir into which solvent from a solvent reservoir diffuses through a semi-permeable membrane. The electrolytic-agent reservoir contains an electrolytic-agent solution in which a quantity of undissolved is disposed to keep the electrolytic-agent solution saturated as solvent diffuses into it.
