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.
Claims15
An open-to-atmosphere storage container for transporting materials at cryogenic temperatures having a micro-fibrous structure adapted for holding a liquified gas such as liquid nitrogen in adsorption and capillary suspension within the interior of the container, said micro-fibrous structure comprising a core permeable to gaseous and/or to liquid nitrogen, with said core being centrally disposed in said container and having at least one void adapted for the removable placement of the transportable materials;
- and a liquified gas adsorption matrix composed of a web of very small diameter inorganic fibers surrounding said core in a multilayered arrangement having an outside diameter conforming to the inside diameter of the storage container.
A storage container for shipping transportable materials at cryogenic temperatures comprising:
- an inner vessel having an open end;
- an outer shell having an open end;
- access means connecting said open end of said outer shell to said open end of said inner vessel such that said inner vessel is suspended from said outer shell in a spaced apart relationship for defining an evacuable space therebetween;
- insulation means disposed within said evacuable space;
- and a micro-fibrous structure located within said inner vessel for holding liquid nitrogen by adsorption and capillary suspension, said micro-fibrous structure comprising a gas permeable core having a void disposed in said inner vessel in alignment with said access means, with said access means providing ingress and egress to said void for removably inserting said transportable materials and a liquid nitrogen adsorption matrix composed of a web of very small diameter inorganic fibers surrounding said core in a multi-layered arrangement with an outside diameter conforming to the inside diameter of said inner vessel.
