Abstract
Abstract A method for rapidly mixing at least one fluid into another by disposing a first fluid within a first conduit and flowing a second fluid within a second conduit substantially concentric with and disposed within the first conduit, the second conduit opening into contact with the fluid within the first conduit. An angular momentum is imparted to the second fluid within the second conduit to thereby form a swirling jet of the second fluid as it exits from the second conduit into contact with the fluid disposed in the first conduit.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
94 words
A method for rapidly mixing at least one fluid into another comprising the steps of: disposing a first fluid at rest within a first conduit; flowing a second fluid within a second conduit substantially concentric with and disposed within said first conduit, said second conduit opening into the fluid within said first conduit; and imparting an angular momentum only to said second fluid within said second conduit to thereby form a swirling jet of said second fluid as it exits from said second conduit into contact with the fluid disposed in said first conduit.
Claim 2
Independent Claim
94 words
A method for rapidly mixing at least one fluid into another comprising the steps of: disposing a first fluid at rest within a first conduit; flowing a second fluid within a second conduit substantially concentric with and disposed within said first conduit, said second conduit opening into the fluid within said first conduit; and imparting an angular momentum only to said second fluid within said second conduit to thereby form a swirling jet of said second fluid as it exits from said second conduit into contact with the fluid disposed in said first conduit.
Claim 3
Independent Claim
130 words
A method for rapidly mixing at least one fluid into another comprising the steps of: disposing a first fluid within a first conduit; flowing a second fluid within a second conduit substantially concentric with and disposed within said first conduit, said second conduit opening into the fluid within said first conduit; and imparting an angular momentum to said second fluid within said second conduit by rotating a plurality of radially extending fins in the path of said fluid flowing in said second conduit, said fins being substantially linearly extending and substantially perpendicular to the direction of the flowing fluid in said second conduit to thereby form a swirling jet of said second fluid as it exists from said second conduit into contact with the fluid disposed in said first conduit.
Claim 4
Independent Claim
130 words
A method for rapidly mixing at least one fluid into another comprising the steps of: disposing a first fluid within a first conduit; flowing a second fluid within a second conduit substantially concentric with and disposed within said first conduit, said second conduit opening into the fluid within said first conduit; and imparting an angular momentum to said second fluid within said second conduit by rotating a plurality of radially extending fins in the path of said fluid flowing in said second conduit, said fins being substantially linearly extending and substantially perpendicular to the direction of the flowing fluid in said second conduit to thereby form a swirling jet of said second fluid as it exists from said second conduit into contact with the fluid disposed in said first conduit.
Claim 5
Independent Claim
97 words
A method for rapidly mixing at least one fluid into another comprising the steps of: flowing a first fluid within a first conduit; flowing a second fluid faster than said first fluid within a second conduit substantially concentric with and disposed within said first conduit, said second conduit opening into the fluid within said first conduit; and imparting an angular momentum only to said second fluid within said second conduit to thereby form a swirling jet of said second fluid as it exits from said second conduit into contact with the fluid disposed in said first conduit.
Claim 6
Independent Claim
97 words
A method for rapidly mixing at least one fluid into another comprising the steps of: flowing a first fluid within a first conduit; flowing a second fluid faster than said first fluid within a second conduit substantially concentric with and disposed within said first conduit, said second conduit opening into the fluid within said first conduit; and imparting an angular momentum only to said second fluid within said second conduit to thereby form a swirling jet of said second fluid as it exits from said second conduit into contact with the fluid disposed in said first conduit.
