Claim 1
Independent Claim
125 words
THE METHOD OF SEPARTING THE COMPONENTS OF AN ANISOTROPIC SOLID SUBSTANCE COMPRISING: MOVING A COMMINGLED STREAM CONSISTING OF A PARTICULATE SOLID SUBSTANCE COMPRISING A PLURALITY OF COMPONENTS AND A FLUID HAVING A PREDETERMINED LEVEL OF ENERGY THEREIN AT A RATE APPROACHING SONIC VELOCITY, RELEASING THE COMMINGLED FLUID AND SOLID STREAM INTO A ZONE TO EFFECT EXPANSION OF SAID FLUID TO A VELOCITY WITHIN THE TRANSONIC RANGE THEREBY CREATING A BLAST, THE CONDITIONS WITHIN SAID ZONE BEING SUCH THAT THERE IS NO GENERATION OF AN ADVERSE BACK PRESSURE EFFECT UPON SAID BLAST, THE CREATION OF SAID BLAST CONVERTING THE AVAILABLE ENERGY IN THE FLUID STREAM TO WORK WITHIN THE SPACE IN WHICH THE BLAST OCCURS, WHICH WORK FUNCTIONS TO SEPARATE THE COMPONENTS OF SAID SOLID SUBSTANCE.
