Inventor: WELTMER WILLIAM R JR
IPC: F16J12/00
Filed: 1991-03-08
Abstract: Abstract of the Disclosure The present invention provides a cryogenic storage container having a pressure vessel surrounded by a vacuum vessel  for maintaining a vacuum between the outer wall of the vacuum vessel and the pressure vessel.  A pair  of  intermediate  and  sub-intermediate  heat  shields  are  disposed between the outer wall of the vacuum vessel and the pressure vessel for intercepting the heat that could otherwise be transferred from the vacuum vessel to the pressure vessel.  The heat intercepted by the intermediate heat shield is absorbed by liquid  nitrogen  contained  within  a liquid nitrogen  container.   The heat intercepted by the sub-intermediate heat shield is preferably absorbed by liquid neon in a  liquid neon storage tank.   The liquid nitrogen and neon absorb heat by undergoing a phase change, from liquid to vapor.  In order to prevent failure of the liquid nitrogen container, the nitrogen is vented to the atmosphere over a period of time.  The vaporized neon, on the other hand, flows into an adsorbant canister  containing  activated  charcoal  to  adsorb  gaseous  neon  for regeneration back to liquid neon at a future time.
