Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
62 words
A method for removing small gas bubbles from a liquid stream to produce a liquid stream having a reduced number of gas bubbles, said method consisting essentially of increasing the pressure on said liquid stream to an increased pressure sufficient to cause said bubbles to dissolve in said liquid stream to produce a liquid stream containing a reduced number of gas bubbles.
Claim 2
Independent Claim
62 words
A method for removing small gas bubbles from a liquid stream to produce a liquid stream having a reduced number of gas bubbles, said method consisting essentially of increasing the pressure on said liquid stream to an increased pressure sufficient to cause said bubbles to dissolve in said liquid stream to produce a liquid stream containing a reduced number of gas bubbles.
Claim 3
Dependent Claim
31 words
The method of claim 1 wherein said liquid stream is passed through a centrifugal pump to increase said pressure and produce said liquid stream having a reduced number of gas bubbles.
Claim 4
Dependent Claim
27 words
The method of claim 2 wherein said liquid stream containing a reduced number of gas bubbles is passed through a length of tubing at turbulent flow conditions.
Claim 5
Dependent Claim
15 words
The method of claim 3 wherein said length of tubing comprises a coil of tubing.
Claim 6
Dependent Claim
63 words
The method of claim 3 wherein said liquid stream containing a reduced number of gas bubbles is passed through said length of tubing at turbulent flow conditions and thereafter passed to a testing device to test said liquid stream containing a reduced number of gas bubbles for the presence of suspended materials in said liquid stream containing a reduced number of gas bubbles.
Claim 7
Dependent Claim
51 words
The method of claim 1 wherein said liquid stream containing a reduced number of gas bubbles is passed to a testing device to test said liquid stream containing a reduced number of gas bubbles for the presence of suspended materials in said liquid stream containing a reduced number of gas bubbles.
Claim 8
Dependent Claim
12 words
The method of claim 6 wherein said tester is an acoustical tester.
Claim 9
Dependent Claim
12 words
The method of claim 6 wherein said tester is an optical tester.
Claim 10
Dependent Claim
19 words
The method of claim 8 wherein said immiscible liquid is oil and wherein said liquid stream is an aqueous
Claim 11
Dependent Claim
19 words
The method of claim 6 wherein said material is a liquid which is substantially immiscible with said liquid stream.
Claim 12
Dependent Claim
13 words
The method of claim 6 wherein said material is finely divided particulate solids.
