  • Shipping container for storing materials at cryogenic temperatures
    Patent number: 4495775
    Abstract: A container for shipping transportable materials at cryogenic temperatures including a vessel which opens to the atmosphere and contains a micro-fibrous structure for holding a liquefied gas such as liquid nitrogen in adsorption and capillary suspension. The micro-fibrous structure comprises a core permeable to liquid and gaseous nitrogen and an adsorption matrix composed of randomly oriented inorganic fibers surrounding the core as a homogeneous body in stable confinement.
    Type: Grant
    Filed: June 22, 1983
    Date of Patent: January 29, 1985
    Assignee: Union Carbide Corporation
    Inventors: John K. Young, Alfred Barthel
  • Cryogenic storage container
    Patent number: 4481779
    Abstract: A storage container for shipping transportable materials at cryogenic temperatures including a vessel which opens to the atmosphere and contains a micro-fibrous structure for holding a liquified gas such as liquid nitrogen in adsorption and capillary suspension. The micro-fibrous structure comprises a core permeable to liquid and gaseous nitrogen and an adsorption matrix composed of a web of inorganic fibers surrounding the core in a multi-layered arrangement.
