Abstract
Abstract A fluid discharge system for use both as a nozzle and as a fluid oxidizer. The system includes a plurality of identical cup-shaped converging members positioned at equally spaced points. A stream of water is directed through all of the converging members and is discharged from the last member. Each converging member acts as a venturi to add air to the water. The air both oxidizes impurities in the water and increases the discharge distance of the stream.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
134 words
Apparatus for maximizing the discharge distance of a liquid comprising: means for directing a liquid under pressure as a stream of predetermined cross-section along a predetermined path, and a plurality of convergent members positioned in sequence along the path, each being open To a gaseous environment to entrain gas in the stream and thereby increase the volume of the fluid in the stream, the convergent ends of the members being approximately equal in size to the cross-section of the liquid stream to increase the velocity of the stream, the last convergent member being positioned to discharge the stream into the gaseous environment without further significant interference by the apparatus, whereby the increased velocity resulting from the increased total fluid volume passing through the successive convergent members will maximize the discharge distance of the liquid.
Claim 2
Dependent Claim
134 words
Apparatus for maximizing the discharge distance of a liquid comprising: means for directing a liquid under pressure as a stream of predetermined cross-section along a predetermined path, and a plurality of convergent members positioned in sequence along the path, each being open To a gaseous environment to entrain gas in the stream and thereby increase the volume of the fluid in the stream, the convergent ends of the members being approximately equal in size to the cross-section of the liquid stream to increase the velocity of the stream, the last convergent member being positioned to discharge the stream into the gaseous environment without further significant interference by the apparatus, whereby the increased velocity resulting from the increased total fluid volume passing through the successive convergent members will maximize the discharge distance of the liquid.
Claim 3
Dependent Claim
43 words
The discharge distance maximizing apparatus according to claim 1 wherein the convergent members form venturis which entrain gas from the gaseous environment into the liquid, and wherein the last convergent member sprays the liquid and the gas entrained therein into the gaseous environment.
Claim 4
Dependent Claim
40 words
The discharge distance maximizing apparatus according to claim 1 further including means for securing the convergent members to the receiving means and to one another, and thereby joining the convergent members and the receiving means into a liquid discharge nozzle.
Claim 5
Dependent Claim
65 words
The discharge distance maximizing apparatus according to claim 1 wherein the convergent members are identical cup-shaped sections supported by pins extending between each convergent member and the next adjacent convergent member, and wherein each cup-shaped section comprises a large diameter end and a small diameter end located downstream from the large diameter end and within the large diameter end of the next adjacent cup-shaped section.
