Abstract: The invention relates to a transport container (1) for helium (He), comprising an inner container (6) for receiving the helium (He); a coolant container (14) for receiving a cryogenic fluid (N2); an outer container (2) in which the inner container (6) and the coolant container (14) are received; a thermal shield (21) in which the inner container (6) is received and which can be actively cooled using the cryogenic fluid (N2), said thermal shield (21) having at least one cooling line (26) which is fluidically connected to the coolant container (14) and in which the cryogenic fluid (N2) can be received in order to actively cool the thermal shield (21); and at least one return line (34, 35), by means of which the at least one cooling line (26) is fluidically connected to the coolant container (14) in order to return the cryogenic fluid (N2) back to the coolant container (14).

Abstract: The present invention relates to the field of take-out food cases, more particularly to a take-out food case for keeping food fresh. The principle is as follows. The temperature information of the heat insulation portion is detected and fed back to the temperature controller by the thermocouple probe. When the detected temperature is lower than the minimum temperature preset by the temperature controller, carbon fiber heating pipes are controlled to heat the food by the temperature controller. When the temperature inside the heat insulation portion reaches to the maximum temperature preset by the temperature controller, carbon fiber heating pipes are controlled to stop heating by means of the temperature controller. When the take-out food case for keeping food fresh is not in use, ultraviolet sterilizing lamps are controlled to perform regular sterilization for the take-out food case by means of the timer.

Abstract: There is provided a cryogenic tank having a dual construction for storing ultralow temperature liquid with improvement which allows simplicity in its construction and readiness of setup and allows reduction in the setup, yet achieves high reliability. For accomplishing the above-noted object, in a cryogenic tank having a dual construction with an inner tank for storing low-temperature liquefaction fluid therein and an outer tank enclosing the bottom and the shell of the inner tank. The inner tank includes a bottomed inner vessel formed of concrete and an inner cold resistant relief covering the inner face of the inner vessel. The outer tank includes a bottomed outer vessel formed of concrete and an outer cold resistant relief covering the inner face of the outer vessel.

Abstract: A cryogenic storage tank having an insulated inner vessel disposed within an outer vessel. A common-access tube or conduit is used to route the various fluid flow lines into the interior of the inner vessel. The use of a common-access tube reduces the number of obstructions that the insulation must accommodate and facilitates the production of the storage tank.
