    摘要: In the present method, cold substances are transferred through a nozzle with moving parts. An insulating boot facilitates the method. The present method is generally suited for use in transferring cryogenic substances such as during the refueling of liquid natural gas vehicles. The present method causes an insulating layer to be created between a removable boot and a nozzle separating the ambient environment from the moving parts of the nozzle, purging the layer with a dry gas such as nitrogen to remove moisture and restricting the incursion of such moisture from the layer and therefore, from the moving parts to avoid freezing up of the moving parts. The layer can also help to avoid freezing up of the abutting interface created between the nozzle and receiving line when the nozzle is removably engaged to a receiving line.

    摘要: A heat exchanger unit having a housing into which a cryogenic liquid is introduced and permitted to evaporate and vaporize into a cryogenic cold gas. A process fluid to be cooled flows in a heat exchanger and heat exchange to cool the process fluid takes place between the cold gas and the heat exchanger, without making direct contact between the cryogenic liquid and the heat exchanger which would cause freezing. The refrigerating capacity of the cryogenic cold gas is replenished by heat exchange contact with the evaporating cryogenic liquid.

    摘要: Injection means for injecting a liquified gas such as sulphur dioxide into a container such as a wine storage tank and avoiding "icing up" the valve mechanism, wherein a three limbed "T" piece of conduit receives the liquified gas, each having a separately controlled valve, one of the limbs being connected to a source of gas which is not liquified, such as nitrogen, the nitrogen blowing the liquified sulphur dioxide gas out of the three limbed "T" piece when two of the valves are opened. The volume of the "T" piece accurately determined the dosage of sulphur dioxide.

    摘要: An easily maintainable interface for magnet dewars which includes a low h leakage disconnect fitting that retains the vacuum integrity of both the dewar and the transfer line is provided. The fitting includes a bayonet-type insert having separate coils disposed about a central conduit for cooling or heating the unit depending upon intended use. Liquid helium is introduced axially through the bayonet which is adjustable to a purge position wherein either gaseous or liquid helium may be introduced to clean, heat or cool the unit, or a flow position wherein liquid helium is passed through the bayonet into the supply line.

    摘要: The present invention relates to a pump (15) for pumping a coolant (9) within a Dewar vessel (1) and to a corresponding Dewar vessel (1) for storing samples in a coolant (9). The Dewar vessel (1) comprises a thermally insulated reservoir (3) for the coolant (9) and a sample vessel (11) provided separately and arranged in the thermally insulated reservoir (3). The reservoir (3) is connected to the sample vessel (11) in such a way that the level of coolant (9) is constant in the sample vessel (11). Pump (15) may help in keeping the level of coolant (9) in the sample vessel (11) constant. For this purpose the pump (15) comprises a chamber (17) with an inlet (19) and an outlet (21), a closing element (23) and a pressure increasing device (25). Therein, the inlet (19) is connectable to the reservoir (3) and the outlet (21) is connectable to a sample vessel (11) of the Dewar vessel (1). The chamber (17) is adapted to fill with coolant (9) through the inlet (19) by gravity and the closing element (23) is adapted to automatically close the chamber (17) when it is full of coolant (9). The pressure increasing device (25) is adapted to increase the pressure within the chamber (17), after the chamber (17) is closed, until the coolant (9) is released through the outlet (21).
