Compressible fluid sonic pressure wave apparatus and method

Claim 1

APPARATUS FOR ATOMIZING FLUENT MATERIALS, SAID APPARATUS COMPRISING, IN COMBINATION, A GAS-OPERATED PRESSURE WAVE GENERATOR INCLUDING A GAS-EXPANDING AND ACCELERATING NOZZLE COMPRISING A BODY MEMBER FORMING A GAS FLOW PASSAGEWAY HAVING AN EXIT OPENING FOR ISSUING A HIGH-SPEED GAS STREAM, MEANS IN SAID BODY MEMBER FOR CONSTRICTING SAID GAS FLOW PASSAGEWAY UPSTREAM FROM SAID EXIT OPENING, MEANS IN SAID BODY MEMBER DOWNSTREAM FROM SAID CONSTRICTING MEANS AND ADJACENT SAID EXIT OPENING OF SAID GAS FLOW PASSAGEWAY FOR GIVING SAID PASSAGEWAY A CROSS-SECTIONAL AREA INCREASING IN THE DIRECTION OF FLOW OF GAS THROUGH SAID NOZZLE, SAID LAST-NAMED MEANS GIVING SAID PASSAGEWAY THE SHAPE OF A FRUSTUM OF A CONE, RESONATOR MEANS, MEANS LOCATED OUTSIDE SAID PASSAGEWAY FOR POSITIONING SAID RESONATOR MEANS DOWNSTREAM FROM SAID EXIT OPENING OF SAID NOZZLE AND INTERCEPTING THE HIGHSPEED GAS STREAM ISSUING FROM SAID EXIT OPENING, AND MEANS FOR FEEDING SAID FLUENT MATERIALS INTO THE GAS FORMING SAID HIGH-SPEED GAS STREAM AT A POSITION WITHIN SAID NOZZLE, SUBJECTING SAID FLUENT MATERIALS TO PRESSURE WAVES DEVELOPED BY SAID GENERATOR AND EFFECTING THE ATOMIZATION OF SAID FLUENT MATERIALS.
