Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
83 words
A METHOD OF HOMOGENIZING A VISCOUS LIQUID WHICHH COMPRISES FLOWING SAID LIQUID FROM A POINT OF ORIGIN TO FORM A STREAM, FLOWING SAID STREAM THROUGH A GASEOUS SPACE AND DEPOSITING SAID STREAM ON THE SURFACE OF A POOL OF SAID LIQUID, THE RELATIONSHIPS BETWEEN THE DENSITY, THE DISTANCE OF FLOW, THE VISCOSITY AND THE VOLUME FLOW RATE OF THE LIQUID FROM THE POINT OF ORIGIN OF THE STREAM RESULTING IN A NM NUMBER BETWEEN 2,000 AND 25,000 WHEN CALCULATED ACCORDING TO THE FORMULA
Claim 2
Independent Claim
83 words

Claim 3
Independent Claim
97 words
A METHOD OF HOMOGENIZING A VISCOUS LIQUID HAVING A VISCOSITY BETWEEN 1.0 AND 3,000 POISES WHICH COMPRISES FLOWING SAID LIQUID FROM A POINT OF ORIGIN TO FORM A STREAM, FLOWING SAID STREAM THROUGH AN ENCLOSED GASEOUS SPACE, MAINTAINING THE DISTANCE OF FLOW OF SAID STREAM FROM ITS POINT OF ORIGIN BETWEEN ABOUT ONE-HALF AND ABOUT TWELVE INCHES, MAINTAINING THE GASEOUS PRESSURE IN SAID ENCLOSED GASEOUS SPACE TO MAINTAIN THE RATE OF FLOW OF SAID STREAM SUFFICIENT TO DEPOSIT SAID STREAM ON THE SURFACE OF A POOL OF SAID LIQUID IN A SPIRAL PATTERN AND WITHIN SAID SPACE.
Claim 4
Independent Claim
