1360 results about "Freezing chamber" patented technology

The controls of a carbon-freezing chamber. Freezing chambers were also sometimes used to seal living beings—though one miscalculation could lead to death. This process required molten carbonite to be released into the chamber which was then flash frozen; a resulting blast of air, soon revealing a solidified encasement.
