Abstract
Abstract Disclosed is novel apparatus and method for introducing various gasses into liquids. This as is commonly done in aerating or oxygenating liquids where growing aquatic life such as fish; instances concerning lagoon and pond treatment, absorption of oxygen in sewage or sewage -activated sludge mixture, introduction of chlorine or carbon dioxide gas into water for chemical treatment thereof. The method includes water treatment comprising the improved diffuser, aerator or sparger apparatus with the result of substantial enlargement in the known beneficial effects of such treatments; also, substantial and unexpected attendant benefit attributable to function of the diffuser apparatus. Principally the apparatus and method reduces the viscosity of water reducing the hydrogen bonding thereof at the time when presented for gas absorbtion. This when utilizing gas for aqueous liquid treatment or treatment of water with suspended pollutants.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
219 words
A diffuser for discharging gas into a body of liquid comprising, in combination, a first gas chamber, inlet means for gas in communication with the interior of said gas chamber, outlet means for gas from said chamber comprising at least one perforation located in an end wall of said chamber opposite said inlet means, a second magnetic chamber defined by spaced apart opposed sidewalls made of material magnetizable or conductive to lines of magnetic flux, magnetic means for inducing magnetic poles in said opposed sidewalls of said magnetic chamber and constructed and arranged to provide essentially horizontal magnetic flux lines across the upper portion of said magnetic chamber, the sidewalls of said magnetic chamber being constructed and arranged so that gas from said gas chamber perforation is discharged into said magnetic chamber between said sidewalls at an open bottom of said magnetic chamber and permitted to rise and leave said chamber through an open top of said chamber when said diffuser apparatus is located beneath the surface of a body of liquid, the sidewalls being further constructed and arranged to permit liquid from said liquid body to enter said magnetic chamber to replace liquid vertically lifted from said magnetic chamber and intersectingsaid flux lines simultaneously with the gas vertically lifing the liquid and also intersecting said magnetic flux lines.
Claim 2
Dependent Claim

A diffuser for discharging gas into a body of liquid comprising, in combination, a first gas chamber, inlet means for gas in communication with the interior of said gas chamber, outlet means for gas from said chamber comprising at least one perforation located in an end wall of said chamber opposite said inlet means, a second magnetic chamber defined by spaced apart opposed sidewalls made of material magnetizable or conductive to lines of magnetic flux, magnetic means for inducing magnetic poles in said opposed sidewalls of said magnetic chamber and constructed and arranged to provide essentially horizontal magnetic flux lines across the upper portion of said magnetic chamber, the sidewalls of said magnetic chamber being constructed and arranged so that gas from said gas chamber perforation is discharged into said magnetic chamber between said sidewalls at an open bottom of said magnetic chamber and permitted to rise and leave said chamber through an open top of said chamber when said diffuser apparatus is located beneath the surface of a body of liquid, the sidewalls being further constructed and arranged to permit liquid from said liquid body to enter said magnetic chamber to replace liquid vertically lifted from said magnetic chamber and intersectingsaid flux lines simultaneously with the gas vertically lifing the liquid and also intersecting said magnetic flux lines.
Claim 3
Dependent Claim
66 words
The diffuser of claim 1 wherein said first gas chamber is elongate with said inlet means at a first end of said chamber and closure means arranged at the second opposite end of said chamber, the sidewall of said chamber extending between said first and second ends parallel to the elongate axis of said chamber, said at least one perforation being located in said elongate sidewall.
Claim 4
Dependent Claim
24 words
The diffuser of claim 2 wherein said first elongate chamber extends through axially located openings in the members defining said second magnetic chamber sidewalls.
Claim 5
Dependent Claim
20 words
The diffuser of claim 2 wherein the outer wall of said first gas chamber is constructed of magnetically conductive material.
Claim 6
Dependent Claim
68 words
The diffuser of claim 2 wherein a plurality of perforations in the sidewall of said gas chamber are arranged in its length between its first inlet end and opposed second closure end and a plurality of said magnetic chambers are positioned relative to said perforations so that gas from at least one perforation is discharged into the open bottom of each of said plurality of said magnetic chambers.
Claim 7
Dependent Claim
33 words
The diffuser of claim 5 wherein said second magnetic chamber sidewalls are constructed and arranged as flat members with edges extending circumferentially around the exterior surface of said first gas chamber outer wall.
Claim 8
Dependent Claim
15 words
The diffuser of claim 1 wherein said magnetic means defines said second magnetic chamber sidewalls.
Claim 9
Dependent Claim
18 words
The diffuser of claim 1 wherein said inlet means is constructed and arranged for gas conduit connection thereto.
Claim 10
Dependent Claim
18 words
The diffuser of claim 1 wherein said second magnetic chamber sidewalls are constructed of magnetic grade stainless steel.
Claim 11
Dependent Claim
26 words
The diffuser of claim 1 wherein said diffuser is arranged in plurality with the inlet of each gas chamber in communication with a common conduit therefor.
