Abstract
Abstract A nozzle for finely dispersing a liquid in a gas stream, usually air or steam, has therein a stem and a cap for diverting the gas stream radially into a resonance chamber. The pressure waves resulting are effective for atomizing a liquid introduced either into the resonance chamber or into the gas stream downstream from the cap.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
116 words
In an acoustic nozzle for finely dispersing a liquid in a gas stream flowing essentially axially through said nozzle, the improvement comprising a stem positioned coaxially within said nozzle, a cap mounted on the downstream end of said stem and having an upstream face and an outer lip, and a disc-shaped resonant cavity, said cavity being coaxial with said gas stream and said stem, said cap causing the direction of flow of said gas stream to become radial at the upstream face thereof and said resonant cavity being essentially coplanar with said upstream face of said cap, whereby said gas stream on entering said cavity radially gives rise to pressure waves suitable for atomizing a liquid.
Claim 2
Dependent Claim
116 words
In an acoustic nozzle for finely dispersing a liquid in a gas stream flowing essentially axially through said nozzle, the improvement comprising a stem positioned coaxially within said nozzle, a cap mounted on the downstream end of said stem and having an upstream face and an outer lip, and a disc-shaped resonant cavity, said cavity being coaxial with said gas stream and said stem, said cap causing the direction of flow of said gas stream to become radial at the upstream face thereof and said resonant cavity being essentially coplanar with said upstream face of said cap, whereby said gas stream on entering said cavity radially gives rise to pressure waves suitable for atomizing a liquid.
Claim 3
Dependent Claim
69 words
In an acoustic nozzle for finely dispersing a liquid in a gas stream flowing essentially axially through said nozzle, the improvement defined in claim 1, further comprising said dispersion member around said stem and a hood surrounding said dispersion member, said hood and said dispersion member defining therebetween a duct connecting with said resonant chamber, said duct serving to introduce a liquid to be dispersed proximate said outer lip.
Claim 4
Dependent Claim
61 words
In an acoustic nozzle for finely dispersing a liquid in a gas stream flowing essentially axially through said nozzle, the improvement defined in claim 1, further comprising a disc-shaped chamber downstream of said cap and said cavity and coaxial with and in communication with said gas stream, said chamber serving to introduce said liquid to be dispersed into said gas stream.
Claim 5
Dependent Claim
35 words
In an acoustic nozzle for finely dispersing a liquid in a gas stream flowing essentially axially through said nozzle, the improvement defined in claim 1, wherein said outer lip is beveled to a sharp edge.
Claim 6
Dependent Claim
37 words
In an acoustic nozzle for finely dispersing a liqiud in a gas stream flowing essentially axially through said nozzle, the improvement defined in claim 1, wherein the interior of said nozzle downstream from said cap is divergent.
Claim 7
Dependent Claim
59 words
In an acoustic nozzle for finely dispersing a liquid in a gas stream flowing essentially axially through said nozzle, the improvement defined in claim 1, further comprising a cylinder firmly engaging said dispersing member proximate the upstream end thereof, said cylinder having ducts therethrough for the passage of said gas stream and said stem being held in said cylinder.
Claim 8
Dependent Claim
60 words
In an acoustic nozzle for finely dispersing a liquid in a gas stream flowing essentially axially through said nozzle, the improvement defined in claim 6, further comprising a block having passages therethrough for the passage of fluid therethrough said block being threaded externally and said hood being threaded internally, said block engaging said hood by said internal and external threads.
Claim 9
Dependent Claim
51 words
In an acoustic nozzle for finely dispersing a liquid in a gas stream flowing essentially axially through said nozzle, the improvement defined in claim 6. wherein said dispersion member has ducts therethrough for passage of fluid, each of said ducts in said dispersion member communicating with a duct in said block.
