    Abstract: A system for dispensing cryogenic liquid to a use device includes a bulk storage tank providing liquid natural gas (LNG) to a sump containing a meter submerged in LNG. A temperature probe is also submerged in the LNG. A dispensing line is positioned between the meter and dispensing hose and includes a dispensing valve. A drain line bypasses the dispensing valve and features a check valve so that LNG trapped in the hose after dispensing is returned to the sump due to pressurization by ambient heat. A capacitance probe is submerged in the LNG in the sump and provides a dielectric that is compared by a microprocessor with the dielectric for pure methane at the same temperature to determine the purity of the LNG. An approximate linear relation between density and dielectric may be used to determine density and mass flow for the LNG from the measured dielectric.

    Abstract: Prefabricated insulated pipe sections are constructed of an inner pipe surrounded by a concentrically-positioned outer pipe. End portions of the inner and outer pipes are joined with bellow members so that an annular space is defined. A portion of the inner pipe is wrapped with layers of insulation material with inert insulating granules positioned between the layers. The annular space is partially evacuated to below atmospheric pressure. Multiple pipe sections may be joined by their inner pipes through brazing or other known methods. The joints and neighboring bellow members on abutting pipe sections are covered by vacuum sleeves that are sealed and provide a vacuum tight joint.
