  • Patent number: 11788666
    Abstract: A plug-in coupling for connecting a first to a second double-walled, vacuum-insulated cryogenic line includes a coupling plug and a coupling socket. The coupling plug has an inner and an outer pipe piece and a first connecting flange and is connected to the first cryogenic line. The coupling socket has an inner and an outer pipe piece and a second connecting flange and is connected to the second cryogenic line. In an assembled state of the plug-in coupling, the coupling plug has been plugged into an open annular gap in the coupling socket. The annular gap is surrounded both at its inner circumference and at its outer circumference by an insulating vacuum, whereby the thermal insulation of the plug-in coupling is improved. This construction makes possible a shorter design of the plug-in coupling, which, while achieving good thermal insulation, is space-saving and easy to handle.

  • Publication number: 20150027136
    Abstract: A two line system for storing and dispensing cryogenic liquids from a bulk storage tank to a secondary container without the use of a cryogenic pump. A first line is in communication with the vapor space of a secondary container and a compressor, the compressor being used to depressurize the secondary container to a point where the bulk storage tank is at a higher pressure than the secondary container. The first line can direct the evacuated gas either into the bulk storage tank, towards separate holding tanks, or towards any other application. A second line is in communication between the bulk storage container and the secondary container. When the compressor is activated, the pressure in the secondary container will fall below the pressure in the bulk storage tank, causing the cryogen to flow from the now higher pressure bulk storage tank into the secondary container.

Operation of the vent and pressure building valves is automated by a controller that receives data from sensors. The controller determines the required saturation pressure for the tank and varies the tank pressure to match and provide a generally constant outlet pressure depending on conditions of the cryogenic liquid.

    Abstract: The present invention relates to an improved heat transfer device and process, such as the heat exchanger included in a process for vaporizing cryogenic fluids industrial gas supply systems. The system having a water bath and heat exchange tube bundle disposed therein operating to vaporize and superheat industrial liquefied gases including fuel gases. Water contained in a tank transfers heat to the bundle by natural convection without benefit of forced water circulation. The water is heated by means such as steam, combustion processes or electric heat and a heat exchange tube bundle submerged within the water tank is used to vaporize and superheat liquefied gas, which passes within the tubular elements of the heat exchange bundle.

  • Patent number: 8291717
    Abstract: A system and method to connect a cryocooler (refrigerator) to a superconducting magnet or cooled object allows for replacement without the need to break the cryostat vacuum or the need to warm up the superconducting magnet or other cooled object. A pneumatic or other type of actuator establishes a thermo-mechanical coupling. The mechanical closing forces are directed perpendicular (cross-axially) to the cryocooler axis and are not applied to the thin wall cryocooler body or to the thin cryostat walls or to the cooled object or to its shield. It is also possible that some of the compressive force be transferred to the cryocooler body. In that case, the extensions are designed so that the forces transferred to the cryocooler thermal stages do not exceed allowable stresses in the cryocooler stage.

  • Patent number: 8261558
    Abstract: Embodiments disclosed herein include insulation used to insulate elongated members, such a pipe or duct, as examples. The insulation can address a number of features, including but not limited to expansion and compression of insulation material, expansion and compression of the elongated member insulated, and the ability to adapt the insulation for elongated member of different sizes and lengths. In one embodiment, the insulation is comprised of at least one plank comprised of a flexible polymeric foam configured to be wrapped around an elongated member. In order for the insulation to self-adjust to compensate for thermal expansion and contraction of the foam material, the plank is comprised of a plurality of flexible polymeric foam profiles. At least one flexible polymeric foam spacer may also be provided that self-adjusts to compensate for thermal expansion and contraction of the elongated member to prevent or reduce gaps in insulation.

  • Patent number: 8214005
    Abstract: A method is specified for operation of an arrangement having at least one superconducting cable, which is surrounded by a cryostat which consists of two metallic tubes, which are arranged concentrically with respect to one another and enclose vacuum insulation between them. The cryostat surrounds not only the cable but also a cavity for a pressurized coolant to pass through. A reservoir area, which is connected to the cryostat, for the coolant is arranged at least at one end of the cryostat and a pump is used which forces the coolant into the cryostat during operation of the arrangement. A valve is arranged at least in the supply path of the coolant from the reservoir area to the cryostat, which valve is open during operation of the arrangement, is connected to at least one unit monitoring the soundness of the cryostat and is blocked when a signal which corresponds to a fault message is present from the monitoring unit, in order to interrupt the supply of the coolant to the cryostat.

  • Patent number: 8173897
    Abstract: A superconducting cable line includes a heat insulation pipe for a fluid for transporting liquid hydrogen, a superconducting cable housed in the heat insulation pipe for a fluid, and heat exchange means for performing a heat exchange between liquid hydrogen and a refrigerant of the cable. The superconducting cable includes a cable core inside a heat insulation pipe for a cable and is housed in the heat insulation pipe for a fluid to form a low temperature environment around the cable and a double heat insulation structure including the heat insulation pipe. Therefore, since heat intrusion into the superconducting cable is reduced and the refrigerant is cooled with liquid hydrogen, the line can reduce energy for cooling the refrigerant.
