Separation of gases from mixtures thereof

Claim 1

IN THE SEPARATION AND CONCENTRATION OF MIXED GASES OF DIFFERENT MOLECULAR WEIGHT, THE STEPS WHICH COMPRISE SETTING UP A CONFINED MOVING STREAM OF SAID MIXTED GASES, JETTING SAID STREAM IN A PREDETERMINED LINE OF FLOW THROUGH A SUBSTANTIALLY UNCONFINED SEPARATING ZONE SUBJECT TO A REDUCED PRESSURE AS A MOVING COLUMN OF FLOW OF SUBSTANTIAL MOMENTUM RESISTANT TO LATERAL DEFLECTION, EXPOSING A SUBSTANTIAL AREA OF THE PERIPHERY OF SAID COLUMN AS A FREE, UNCONFINED SURFACE IN SAID SEPARATING ZONE, CONTINUALLY MAINTAINING THE PREDETERMINED, UNITARY INTEGRITY OF SAID FREE SURFACE BY THE VELOCITY AND MOMENTUM OF FLOW OF SAID COLUMN, CONTINUOUSLY EFFECTING SELECTIVE MOLECULAR DIFFUSION OF GAS THROUGH SAID FREE SURFACE INTO SAID SEPARATING ZONE, CONTINUOUSLY RECOVERING FROM SAID SEPARATING ZONE PRODUCT GAS ESCAPING FROM SAID FREE SURFACE, RICH IN RESPECT TO SAID GAS OF LOWER MOLECULAR WEIGHT AND SEPARATELY RECOVERING THE RESIDUAL FLOW OF SAID COLUMN BEYOND SAID SEPARATING ZONE AS A PRODUCT RELATIVELY RICH IN SAID HIGHER MOLECULAR WEIGHT GAS.
