Abstract
Abstract The apparatus of the present invention would relate to an air diffuser assembly which would comprise an aerator body having a plurality of side walls connected to form an enclosure and at least a pair of intersecting angularly oriented side walls forming an air container envelope for retaining an air volume therewithin. It would also have an air inlet adapted to convey air into said air body at the air container envelope, and a plurality of tear-shaped openings being provided in the body below the air container envelope allowing air to discharge air from the body through the tear-shaped openings, with each of the tear-shaped openings providing an upper pointed portion which would minimize the bubble size of air discharged through the openings. The apparatus would also comprise a baffle plate mounted within the enclosure at the air inlet, the baffle plate preventing the short circuit travel of air received by said enclosure to the tear-shaped openings placed on the body adjacent the air inlet. There would also be included an attachment means associated with the air inlet for attaching the aerator body to an air conveying conduit.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
121 words
An air diffuser assembly comprising: a. an aerator body comprising a plurality of side walls connected to form an enclosure, and at least a pair of intersecting angularly oriented side walls forming an air container envelope for retaining an air volume therewithin; b. an air inlet adapted to convey air into said air body at said air container envelope; c. a plurality of tear-shaped openings being provided in said body below said air container envelope allowing air to discharge from said body through said tear-shaped openings, each of said tear-shaped openings providing an upper pointed portion which minimizes bubble-size of air discharged through said openings, and a lower circular portion communicating with said upper pointed portion, forming together said tear-shaped opening.
Claim 2
Dependent Claim
121 words
An air diffuser assembly comprising: a. an aerator body comprising a plurality of side walls connected to form an enclosure, and at least a pair of intersecting angularly oriented side walls forming an air container envelope for retaining an air volume therewithin; b. an air inlet adapted to convey air into said air body at said air container envelope; c. a plurality of tear-shaped openings being provided in said body below said air container envelope allowing air to discharge from said body through said tear-shaped openings, each of said tear-shaped openings providing an upper pointed portion which minimizes bubble-size of air discharged through said openings, and a lower circular portion communicating with said upper pointed portion, forming together said tear-shaped opening.
Claim 3
Dependent Claim
42 words
The apparatus of claim 1, further comprising a baffle plate mounted within said enclosure at said air inlet, said baffle plate preventing the short circuit travel of air received by said enclosure tear-shaped openings placed on said body adjacent said air inlet.
Claim 4
Dependent Claim
22 words
The apparatus of claim 1 wherein said plurality of said side walls have an angular inclination of at least sixty-two (62°) degrees.
Claim 5
Dependent Claim
41 words
The apparatus of claim 1, wherein said tear-shaped openings each provide an upper point at the upper portion thereof, said tear-shaped opening being substantially of equal elevation, and said width said point portions being at the upper most elevational level thereof.
Claim 6
Dependent Claim
94 words
The apparatus of claim 1, further comprising attachment means associated with said air inlet for attaching said aerator body to an air conveying conduit, said attachment means comprising: a. an air flow conduit said conduit having a plurality of annular grooves provided on its outer surface; b. a connector pipe assembly providing a plurality of annular projections, corresponding to and registering during operation with said annular groove; and c. an opening provided in the upper portion of said aerator body, said opening allowing the passage of at least a portion of said conduit therethrough.
Claim 7
Dependent Claim
28 words
The apparatus of claim 1, wherein the diffuser assembly further comprises a diffuser means for allowing the flow of fluids into the lower portion of said aerator body.
Claim 8
Dependent Claim
28 words
The apparatus of claim 6, wherein the diffuser means further comprises a rib portion for diffusing the flow of fluids into the lower portion of said aerator body.
Claim 9
Dependent Claim
25 words
The apparatus of claim 7, wherein the diffuser means further comprises clearance openings for allowing the discharge of settled solids out of said aerator body.
Claim 10
Dependent Claim
32 words
The apparatus of claim 7, wherein the rib portion comprises side walls having an angular inclination of at least sixty-two (62°) degrees and intersecting at a top point within said aerator body.
