I don't think this patent is relevant, Jerry. It seems to be
a perfectly normal, "garden variety" Ranque-Hilsch vortex tube.
These things have been around for years. You can buy them=20
off-the-shelf from at least two companies in the USA, easily
findable through a web search. They are used for refrigeration=20
and for spot heating and cooling in industrial applications.
