Claim 1
Independent Claim
109 words
THE METHOD OF TREATING A SOLUTION OF PLASTIC MATERIAL WHICH COMPRISES PASSING SAID SOLUTION ALONG A CONFINED PATH AT A PRESSURE SUFFICIENT TO MAINTAIN SAID DISPERSION IN THE LIQUID PHASE, ABRUPTLY RELEASING SAID PRESSURE AND SUBSEQURNTLY PASSING SAID DISPERSION ALONG SAID CONFINED PATH FOR A DISTANCE SUFFICIENT TO EFFECT SOLIDIFICATION OF THE PLASTIC MATERIAL, DISCHARGING THE SOLIDIFIED MATERIAL FROM SAID CONFINED PATH, CONTACTING THE DISCHARGED MATERIAL CLOSELY ADJACENT THE DISCHARGE REION WITH A CUTTING EDGE HAVING SUFFICIENT VELOCITY TO EFFECT DISINTEGRATION OF THE SOLIDIFIED MATERIAL, MAINTIANING A REDUCED PRESSURE IN THE REGION OF SAID DISCHARGE ZONE TO FLASH OFF SAID SOLVENT, AND RECOVERNG THE RESULTING DISINTEGRATED SOLID PLASTIC MATERIAL.
