Abstract
Abstract A gas diffuser for admitting gas into a body of liquid is disclosed. The diffuser includes an elongated body with a chamber extending inwardly from an open face thereof and a resilient strip covering the chamber and secured to the body so as to flex at its ends under the urging of the pressure of gas in the chamber. The body includes a pair of cavities adjacent its end walls. The cavities act as resonance chambers causing the gas therein to resonate with the strip as the gas stream flows across the cavities. In addition, the strip is tapered from an intermediate portion thereof to its ends.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
113 words
A diffuser comprising a body having a chamber therein with means for supplying gas under pressure thereto, one face of said chamber comprising a resilient closure member fixed at one point to the body and having edge portions seated on the body, said closure member being arranged to vibrate in a direction normal to its surface under pressure of gas in the chamber to release gas from the chamber, the body having a cavity therein which is in communication with the chamber when the closure is vibrating and said cavity located such that gas passing through the chamber passes over the cavity causing the gas in the cavity to resonate with the strip.
Claim 2
Dependent Claim
113 words
A diffuser comprising a body having a chamber therein with means for supplying gas under pressure thereto, one face of said chamber comprising a resilient closure member fixed at one point to the body and having edge portions seated on the body, said closure member being arranged to vibrate in a direction normal to its surface under pressure of gas in the chamber to release gas from the chamber, the body having a cavity therein which is in communication with the chamber when the closure is vibrating and said cavity located such that gas passing through the chamber passes over the cavity causing the gas in the cavity to resonate with the strip.
Claim 3
Dependent Claim
28 words
A diffuser as defined in claim 1 in which said cavity is positioned in the edge of the body under the edge portion against which the closure seats.
Claim 4
Dependent Claim
43 words
A diffuser as defined in claim 1 in which said body and the chamber therein is generally of rectangular shape with said closure extending in the direction of the length of the body, the cavity being located adjacent one end of the chamber.
Claim 5
Dependent Claim
78 words
A diffuser as defined in claim 1 in which said body and the chamber therein is generally of rectangular shape with the resilient closure comprising a strip extending lengthwise over the chamber and fixed to the body midway between its ends with the sides and ends of the strip seating on the sides and ends of the body, the body having a resonance cavity therein adjacent to each end of the body and over which the strip extends.
Claim 6
Dependent Claim
37 words
A diffuser as defined in claim 1 in which said resilient closure tapers from maximum thickness adjacent the point where it is fixed to the body to minimum thickness at the edge most remote from said point.
Claim 7
Dependent Claim
25 words
A diffuser as defined in claim 4 in which said strip tapers in thickness lengthwise from a maximum midway between its ends toward both ends.
Claim 8
Dependent Claim
101 words
In a gas diffuser including an elongated body having side and end walls and an open face defining a chamber therein, an elongated resilient strip covering the chamber, and a retainer extending across the strip for securing the strip to the body to allow the ends of the strip to flex away from the body under the urging of the pressure of gas in the chamber, the improvement therewith comprising: said body having at least one resonance cavity therein located such that gas passing through the chamber passes over the cavity causing gas in the cavity to resonate with the strip.
Claim 9
Dependent Claim
101 words
In a gas diffuser including an elongated body having side and end walls and an open face defining a chamber therein, an elongated resilient strip covering the chamber, and a retainer extending across the strip for securing the strip to the body to allow the ends of the strip to flex away from the body under the urging of the pressure of gas in the chamber, the improvement therewith comprising: said body having at least one resonance cavity therein located such that gas passing through the chamber passes over the cavity causing gas in the cavity to resonate with the strip.
Claim 10
Dependent Claim
23 words
The improvement as set forth in claim 7 wherein said resonance cavity extends from the chamber towards the closed end of the body.
Claim 11
Dependent Claim
17 words
The improvement as set forth in claim 7 wherein said resonance cavity extends laterally of the chamber.
Claim 12
Dependent Claim
20 words
The improvement as set forth in claim 7 wherein said resonance cavity is adjacent an end wall of the body.
Claim 13
Dependent Claim
46 words
The improvement as set forth in claim 7 wherein said body has a pair of resonance cavities, each of which extends transversely of the body from the chamber to adjacent the closed face, and each of the cavities is adjacent an end wall of the body.
Claim 14
Dependent Claim
119 words
In a gas diffuser including an elongated body having side and end walls and an open face defining a chamber therein, an elongated resilient strip covering the chamber, and a retainer extending across the strip for securing the strip to the body to allow the ends of the the strip to flex away from the body under the urging of the pressure of gas in the chamber, the improvement therewith comprising: said body having at least one resonance cavity therein located such that gas passing through the chamber passes over the cavity causing gas in the cavity to resonate with the strip; said strip being tapered from an intermediate portion thereof to at least one of the ends thereof.
Claim 15
Dependent Claim
