Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
57 words
The process of claim 1 wherein the flowable materials are forced through the first zone against the radially outwardly directed centrifugal force present in the first zone; and wherein the materials are forced through the at least one additional zone in cooperation with the radially outwardly directed centrifugal force present in said at least one additional zone.
Claim 2
Dependent Claim
99 words
The process of claim 1 wherein the at least one additional zone comprises a second zone and a third zone, and wherein materials are forced through the second zone in cooperation with the radially outwardly directed centrifugal force present in said second zone, said materials are removed from the second zone, said materials are forced through the third zone in cooperation with the radially ouTwardly directed centrifugal force present in said third zone, and the centrifugal force in said first zone tending to pull material in the opposite direction from the centrifugal forces in said second and third zones.
Claim 3
Dependent Claim
42 words
The process of claim 3 wherein said first and second zones are directly adjacent each other, and have a common material passage zone, and wherein said second and third zones are directly adjacent each other and have a common material passage zone.
Claim 4
Dependent Claim
20 words
The process of claim 1 wherein said forces in said first and said at least one additional zone are coaxial.
Claim 5
Dependent Claim
13 words
The process of claim 1 wherein said zones are of substantially equal size.
Claim 6
Dependent Claim
16 words
The process of claim 1 wherein the materials are forced vertically upward into said first zone.
Claim 7
Dependent Claim
16 words
The process of claim 1 wherein said forces in said zones are of substantially equal magnitude.
Claim 8
Dependent Claim
63 words
The process of claim 1 wherein said at least one addition zone comprises a second zone, and said materials are forced through a second zone in cooperation with the radially outward directed centrifugal force present in said second zone, and the centrifugal force in said first zone tending to pull material in the opposite direction from the centrifugal force in said second zone.
Claim 9
Dependent Claim
23 words
The process of claim 9 wherein said first and second zones are directly adjacent each other and have a common material passage zone.
