    Abstract: A system for dispensing a cryogenic fluid includes a bulk tank configured to contain a supply of a cryogenic liquid, a first sump and a first liquid feed valve configured to direct liquid from the bulk tank to the first sump when in an open condition and to prevent transfer of liquid from the bulk tank to the first sump when in a closed condition. A first positive displacement pump is positioned within the first sump and configured to pump and be submerged in cryogenic liquid when the first sump contains cryogenic liquid above a predetermined liquid level within the first sump. A delivery line is in fluid communication with an outlet of the first positive displacement pump and is configured to direct cryogenic fluid from the first positive displacement pump to a use device when the first positive displacement pump is activated.

    Abstract: A cryogenic delivery tank includes a vessel having inner and outer shells and an interior that may contain a cryogenic liquid with a headspace above. A transfer pipe passes through the interior of the vessel and includes a head space coil positioned within an upper portion of the interior and a liquid side coil positioned in the lower portion of the interior. The transfer pipe has a first port adjacent to the head space coil and a second port adjacent to the liquid side coil. The first and second ports of the transfer pipe are configured to be removably attached to a second tank.

    Abstract: A cryocooler is described that can include a pressure wave generator, and a refrigeration device (for example, a cold-head), which can be used to liquefy a gas when the gas is exposed to a surface of the refrigeration device. The pressure wave generator can include one or more motors. Each motor can include a stator, and at least one electrical coil wound around a portion of the stator. The electrical coil can generate a reversing magnetic field when alternating electric current is passed through the electrical coil. The motor can further include a pressurized container that can be placed within the space enclosed by the stator, and a piston that can be placed inside the pressurized container. The stators can be placed external to the pressurized container. The piston is made by combining magnets that have opposite and transverse polarities, and are combined adjacently on a common reciprocating axis.

    Abstract: A system for transferring cryogenic fluid from a dispensing tank to a receiving tank is disclosed. The dispensing tank stores a supply of cryogenic liquid with a dispensing tank headspace above the liquid. A compressor has an inlet connected to the headspace of a receiving tank and an outlet connected to the headspace of the dispensing tank. A liquid transfer line is in fluid communication with the liquid side of the dispensing tank and the receiving tank. Cryogenic liquid is transferred from the dispensing tank to the receiving tank when the compressor is activated so as to transfer vapor from the headspace of the receiving tank to the headspace of the dispensing tank to create a pressure differential between the dispensing and receiving tanks.

    Abstract: Cooling of a meter by liquid flowing in a flow that is reverse from dispensing flow is described. A plurality of tubes is configured to transport a plurality of fluids comprising a first fluid and a second fluid. Dispense valves attached to corresponding tubes are configured to open when the first fluid is dispensed from a pump to a first outlet. Recirculation valves attached to respective tubes are configured to open when the second fluid is transported from the pump to a second outlet. A meter attached to a tube of the plurality of tubes is configured to measure properties of a fluid when the fluid flows through the tube, wherein the fluid is one of the first fluid and the second fluid. The meter is configured to sense reverse flow when the second fluid flows from the outlet section to the inlet section.
