A new patent has been filed. It is in the application phase.
Essentially the same as the first one from skimming over it. Really can't be bothered going through the entire thing at this point. It has the same title, and I'd noticed that it included liquid nitrogen. Looks like there are some specifics which they'd like to include.
Application number 16/682,003. Link
Applied 13th November 2019.
Published 19th March 2020.
Drawings if anyone is interested.
