Inverse dome-shaped end of a super vacuum isolation tank e.g. for low temperature liquid gas, has main body with curved surface and small cap end connected to main body

摘要

The inverse dome-shaped end has a main body (1221) with a curved surface and a small cap end (1222), which is connected to the main body. The small end has a curved surface which is opposite the curved surface of the main body. The small end is connected with the main body by an extension. An independent claim is included for a super vacuum isolation tank.
