Abstract
Abstract A plural compartment enclosing housing carries a baffle and filtering media in liquid form in each compartment. Combustion exhaust gases are passed to a first compartment through said liquid and subsequently to said second compartment. Baffling and filtering occurs in the liquids of each compartment. Means then permit filtered exhaust gas to be exhausted from the second compartment with a portion thereof along with entrained liquid passing through a flowback device to the first compartment. A stationary liquid reservoir is established in each compartment. Pollutants are rapidly and efficiently removed from the combustion exhaust gas making the device highly useful in automobile and truck applications in place of conventional mufflers.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
50 words
An emission control muffler device in accordance with claim 1 wherein said means for collecting said exhaust gas in said first compartment, said means for passing said exhaust gas out of said second compartment and said flowback means define inlets spaced above the level of said liquid in said compartments.
Claim 2
Dependent Claim
49 words
An emission control muffler device in accordance with claim 2 wherein said exhaust means for passing an exhaust gas into said first compartment comprises a plurality of pipes with at least one of said pipes defining a plurality of perforations through which said exhaust gas passes into said liquid.
Claim 3
Dependent Claim
64 words
An emission control muffler device in accordance with claim 3 wherein said means for collecting said exhaust gas in said first compartment and for passing said gas to said second compartment comprises a second plurality of pipes, said second plurality of pipes comprising at least one pipe having a plurality of perforations therein for passing said gas to said liquid in said second compartment.
Claim 4
Dependent Claim
35 words
An emission control muffler device in accordance with claim 4 wherein said flowback means comprises a flowback pipe having an opening positioned in said first compartment below the level of said liquid in said compartment.
Claim 5
Dependent Claim
91 words
An emission control muffler device for use in removing contaminants from and mufflIng noise of an internal combustion engine, said device comprising first and second separate liquid reservoirs, means for passing exhaust gas from an engine through said first and second liquid reservoirs, pipe means for maintaining said first liquid reservoir at a predetermined level without addition of supplementary liquid by passing a portion of said exhaust gas along with entrapped liquid from said second reservoir to said first reservoir, and means for collecting and passing said gas to the atmosphere.
Claim 6
Dependent Claim
35 words
An emission control muffler device in accordance with claim 1 wherein said flowback means comprises a flowback pipe having an opening positioned in said first compartment below the level of said liquid in said compartment.
Claim 7
Independent Claim
94 words
A method of muffling and filtering an exhaust gas from an internal combustion engine, said method comprising, passing said gas through a first stationary liquid reservoir, retrieving said gas from said liquid reservoir and passing it through a second stationary liquid reservoir, retrieving said gas from said second stationary liquid reservoir and discharging a portion of it to the atmosphere while a portion of said gas retrieved from said secondary stationary liquid reservoir is passed back to said first stationary liquid reservoir along with entrapped liquids carried over from said second stationary liquid reservoir.
Claim 8
Dependent Claim
27 words
A method of muffling and filtering an exhaust gas from an internal combustion engine in acordance with the method of claim 8 wherein said liquid is water.
