Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
83 words
A DEVICE FOR SEPARATING LIQUIDS OF DIFFERENT SPECIFIC GRAVITY COMPRISING: AN OUTSIDE CONTAINER, AN INSIDE CONTAINER, MEANS FASTENING SAID INSIDE CONTAINER INTO SAID OUTSIDE CONTAINER AND OVERFLOW MEANS FOR OVERFLOWING LIQUID OF LOW SPECIFIC GRAVITY FROM THE INSIDE CONTAINER INTO THE OUTSIDE CONTAINER WHILE RETAINING HIGH SPECIFIC GRAVITY LIQUID IN THE INSIDE CONTAINER TO SEPARATE SAID LOW FROM SAID HIGH SPECIFIC GRAVITY LIQUID. AND A HANDLE ON THE FASTENED CONTAINERS FOR CONCURRENTLY POURING THEIR RESPECTIVE CONTENTS INTO SEPARATE RECEPTACLES BY TIPPING SAID CONTAINERS.
Claim 2
Independent Claim

Claim 3
Independent Claim
113 words
A METHOD OF SEPARATING LIQUIDS OF DIFFERENT SPECIFIC GRAVITY COMPRISING THE STEPS OF POURING COMMINGLED LIQUIDS INTO THE INSIDE ONE OF TWO NESTED CONTAINERS TO CAUSE THE LIQUID OF LOWER SPECIFIC GRAVITY TO SEPARATE FROM THE LIQUID OF HIGHER SPECIFIC GRAVITY AND RISE TOWARD THE TOP OF SAID INSIDE CONTAINER, AND CONTINUING TO POUR INTO SAID INSIDE CONTAINER TO OVERFLOW SAID LIQUID OF LOWER SPECIFIC GRAVITY INTO THE OUTER OF SAID TWO NESTED CONTAINERS UNTIL SUBSTANTIALLY ALL OF SAID SEPARATED LIQUID OF LOWER SPECIFIC GRAVITY HAS OVERFLOWED INTO SAID OUTER CONTAINER, PLUS THE STEP OF POURING SIMULTANEOUSLY FROM SAID ONE AND ANOTHER CONTAINERS INTO SEPARATE RECEPTACLES FOR SAID LIQUIDS OF DIFFERENT SPECIFIC GRAVITY.
