Abstract
Abstract Mixing apparatus including a cylindrical mixing chamber having a fluid inlet at one end, a frusto-conical tubular end piece connected to the other end and flaring outwardly by progressively increasing in diameter in an outward direction to form a fluid outlet. The cylindrical mixing chamber has a plurality of rows of openings inclined inwardly towards the fluid outlet. An outer jacket surrounds the cylindrical mixing chamber in spaced relationship therewith to form a liquid receiving chamber. The inlet is shaped as to introduce liquid tangentially into said liquid receiving chamber so as to obtain greater water flow and less turbulence in said liquid receiving chamber.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
105 words
Mixing apparatus including a cylindrical mixing chamber having a fluid inlet at one end, a frusto-conical tubular end piece connected to the other end and flaring outwardly by progressively increasing in diameter in an outward direction to form a fluid outlet, said cylindrical mixing chamber having a plurality of rows of openings inclined inwardly towards said fluid outlet; and outer jacket surrounding said cylindrical mixing chamber in spaced relationship therewith to form a liquid receiving chamber, and inlet means shaped as to introduce liquid tangentially into said liquid receiving chamber so as to obtain greater water flow and less turbulence in said liquid receiving chamber.
Claim 2
Dependent Claim
105 words
Mixing apparatus including a cylindrical mixing chamber having a fluid inlet at one end, a frusto-conical tubular end piece connected to the other end and flaring outwardly by progressively increasing in diameter in an outward direction to form a fluid outlet, said cylindrical mixing chamber having a plurality of rows of openings inclined inwardly towards said fluid outlet; and outer jacket surrounding said cylindrical mixing chamber in spaced relationship therewith to form a liquid receiving chamber, and inlet means shaped as to introduce liquid tangentially into said liquid receiving chamber so as to obtain greater water flow and less turbulence in said liquid receiving chamber.
Claim 3
Dependent Claim
29 words
Mixing apparatus as recited in claim 1 together with a curved entrance piece to said cylindrical mixing chamber progressively decreasing in diameter to that of said cylindrical mixing chamber.
Claim 4
Dependent Claim
49 words
Mixing apparatus as recited in claim 1 wherein said last mentioned inlet means comprises a pair of diametrically opposite inlets angularly disposed towards diametrically opposite sides of said liquid receiving chamber at right angles to said diametrically opposite inlets to effect said tangential flow in said liquid receiving chamber.
Claim 5
Dependent Claim
62 words
Mixing apparatus as recited in claim 3 wherein said plurality of rows of openings are angularly skewed relative to the longitudinal axis of said mixing chamber so that liquid flowing through said rows of openings has a component of motion toward said fluid outlet of said mixing chamber and a rotary component of motion relative to the radius of said mixing chamber.
Claim 6
Dependent Claim
29 words
Mixing apparatus as recited in claim 4 together with a curved entrance piece to said cylindrical mixing chamber progressively decreasing in diameter to that of said cylindrical mixing chamber.
Claim 7
Dependent Claim
27 words
Mixing apparatus as recited in claim 3 wherein said pair of diametrically opposite inlets are progressively curved towards said diametrically opposite sides of said liquid receiving chamber.
Claim 8
Dependent Claim
41 words
Mixing apparatus as recited in claim 3 together with quick coupling means at the outer ends of said pair of diametrically opposite inlets, said quick coupling means comprising a pair of closely spaced rings with an inner ring of smaller diameter.
Claim 9
Dependent Claim
26 words
Mixing apparatus as recited in claim 1 wherein said plurality of rows of openings are flared inwardly in diameter in the direction towards said fluid outlet.
Claim 10
Dependent Claim
20 words
Mixing apparatus as recited in claim 1 wherein the liquid entering said inlet means is raw water to be treated.
Claim 11
Dependent Claim
24 words
Mixing apparatus as recited in claim 1 with the skewed rows of openings formed in a hardened material to permit the handling of slurries.
