Abstract
Abstract A method is disclosed for mixing liquids in closed containers wherein the container is partially filled with a liquid such as paint and is moved over a closed path in a vertical plane such that the vertical velocity component of fluid movement causes a force component in the fluid within the container to displace the air therein away from the top of the container.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
63 words
A method of mixing liquid compositions in closed containers, comprising the steps of: a. partially filling a container with a liquid composition, leaving an air volume therein; b. moving the container about a closed path in a vertical plane at a cyclical rate; and c. setting the cyclical rate so as to disperse the liquid composition into the air volume in said container.
Claim 2
Independent Claim
63 words
A method of mixing liquid compositions in closed containers, comprising the steps of: a. partially filling a container with a liquid composition, leaving an air volume therein; b. moving the container about a closed path in a vertical plane at a cyclical rate; and c. setting the cyclical rate so as to disperse the liquid composition into the air volume in said container.
Claim 3
Dependent Claim
30 words
The method of claim 1, further comprising the step of continuing the movement of said container about said closed path for a time period of from 15 to 90 seconds.
Claim 4
Dependent Claim
19 words
The method of claim 1, wherein said closed path includes a vertical displacement of from 3/16-inch to 11/8 inches.
Claim 5
Dependent Claim
21 words
The method of claim 1 wherein said cyclical rate is set between 400 revolutions per minute and 2100 revolutions per minute.
Claim 6
Independent Claim
32 words
The method of claims 3 or 4, further comprising the step of continuing the movement of said container about said closed path for a time period of from 15 to 90 seconds.
Claim 7
Independent Claim
94 words
A method of mixing liquid compositions in a closed cylindrical container, comprising the steps of: a. partially filling said container with a liquid composition and filling the remainder of said container with an air volume; b. positioning the cylindrical axis of said container horizontally; c. moving said container about a closed path having an axis parallel with said cylindrical axis, said closed path being in a vertical plane; and d. selecting the rate of movement of said container about said closed path so as to turbulently intermix said liquid composition and said air volume.
Claim 8
Independent Claim
94 words
A method of mixing liquid compositions in a closed cylindrical container, comprising the steps of: a. partially filling said container with a liquid composition and filling the remainder of said container with an air volume; b. positioning the cylindrical axis of said container horizontally; c. moving said container about a closed path having an axis parallel with said cylindrical axis, said closed path being in a vertical plane; and d. selecting the rate of movement of said container about said closed path so as to turbulently intermix said liquid composition and said air volume.
Claim 9
Dependent Claim
30 words
The method of claim 6, further comprising the step of continuing the movement of said container about said closed path for a time period of from 15 to 90 seconds.
Claim 10
Dependent Claim
19 words
The method of claim 6, wherein said closed path includes a vertical displacement of from 3/16-inch to 11/8 inches.
Claim 11
Dependent Claim
21 words
The method of claim 6, wherein said cyclical rate is set between 400 revolutions per minute and 2100 revolutions per minute.
Claim 12
Independent Claim
32 words
The method of claims 8 or 9, further comprising the step of continuing the movement of said container about said closed path for a time period of from 15 to 90 seconds.
