Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
190 words
An apparatus for mixing two liquid streams comprising: a. a first nozzle; b. means for introducing a first stream to said first nozzle; c. a second nozzle concentrically located within faid first nozzle and having its throat at least closely adjacent to the throat of said first nozzle; d. means for introducing a second stream to said second nozzle; e. a tapered flow control means concentrically located within and axially movable with respect to said throat of said second nozzle whereby the nozzle opening area is adjustable to increase or decrease the flow of said second stream through said second nozzle upon axial movement of said flow control means; and f. a deflecting means located outside of said second nozzle but at least closely adjacent thereto for outwardly deflecting said second stream flowing from said second nozzle into a diverging spray pattern into said throat of said first nozzle, said deflecting means being connected to said flow control means whereby upon axial movement of said flow control means away from said throat of said second nozzle said deflecting means moves more closely adjacent to said opening of said second nozzle.
Claim 2
Independent Claim
190 words
An apparatus for mixing two liquid streams comprising: a. a first nozzle; b. means for introducing a first stream to said first nozzle; c. a second nozzle concentrically located within faid first nozzle and having its throat at least closely adjacent to the throat of said first nozzle; d. means for introducing a second stream to said second nozzle; e. a tapered flow control means concentrically located within and axially movable with respect to said throat of said second nozzle whereby the nozzle opening area is adjustable to increase or decrease the flow of said second stream through said second nozzle upon axial movement of said flow control means; and f. a deflecting means located outside of said second nozzle but at least closely adjacent thereto for outwardly deflecting said second stream flowing from said second nozzle into a diverging spray pattern into said throat of said first nozzle, said deflecting means being connected to said flow control means whereby upon axial movement of said flow control means away from said throat of said second nozzle said deflecting means moves more closely adjacent to said opening of said second nozzle.
Claim 3
Dependent Claim
24 words
The apparatus of claim 1 wherein said flow control means is an elongated stem extending into said second nozzle and having a tapered end.
Claim 4
Dependent Claim
58 words
The apparatus of claim 2 wherein said deflecting means comprises a neck and a cone, said neck being of smaller diameter than said stem and connecting said tapered end of said stem to said cone, said cone being concentrically mounted on said neck and said cone being axially aligned with said stem and flared towards said tapered end.
Claim 5
Dependent Claim
47 words
The apparatus of claim 3 wherein the means for introducing the first and second streams are pipes and the pipe for the second stream is concentrically located within the pipe for the first stream and said stem is concentrically located within said pipe for said second stream.
Claim 6
Dependent Claim
32 words
The apparatus of claim 4 wherein said first stream is water and said second stream is a heavy ends residue stream from an ethyl chloride process which contains some metal halide catalyst.
