Abstract: A tank system and method for storing cryogenic liquids includes a support cooling channel to reduce heat leak into the vessel of a fuel tank. The fuel tank may store either liquid natural gas or liquid hydrogen or another cryogenic liquid. A cooling fluid is transferred from a second vessel into the support cooling channel of the fuel tank.

Abstract: A system for dispensing a cryogenic fluid includes a bulk tank containing a supply of cryogenic fluid. A heating circuit includes an intermediate tank and a heating device and has an inlet in fluid communication with the bulk tank and an outlet. A bypass junction is positioned between the bulk tank and the inlet of the heating circuit. A bypass circuit has an inlet in fluid communication with the bypass junction and an outlet so that a portion of cryogenic fluid from the bulk tank flows through the heating circuit and is warmed and a portion flows through the bypass circuit. A mixing junction is in fluid communication with the outlets of the bypass circuit and the heating circuit so that warmed cryogenic fluid from the heating circuit is mixed with cryogenic fluid from the bypass circuit so that the cryogenic fluid is conditioned. A dispensing line is in fluid communication with the mixing junction so that the conditioned cryogenic fluid may be dispensed.

Abstract: A robot comprising a base forming an inner chamber and having an opening, a first link supported by the base and arranged for translational movement generally along a first axis relative to the base, a second link supported by the first link and arranged for rotary motion relative to the first link about a second axis generally parallel to the first axis, the second link extending from the inner chamber through the opening into an outer region, a third link supported by the second link and arranged for rotary motion relative to the second link about a third axis generally parallel to the first axis, a first actuator arranged to control the translational movement of the first link relative to the base, a second actuator arranged to control the rotary motion of the second link relative to the first link, a third actuator supported by the second link and arranged to control the rotary motion of the third link relative to the second link, and a seal between the inner chamber and the outer region arranged to isola

Abstract: A quick closing shut-off valve includes an inlet, an outlet and a passage there between. A closing element blocks the passage when in the closed position. The closing element is interconnected to a piston via a pull rod. The piston is positioned within a working chamber that communicates with the valve outlet. A safety valve also communicates with the working chamber and is positioned above the piston. As a result, when the pressure within the tank, and thus in the working chamber, reaches a maximum permissible pressure, the safety valve opens and the pressure above the piston decreases. The piston rises as a result and pulls the closing element via the pull rod into the closed position so that the valve is closed.
