Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 116 words
In a gas cleaning apparatus including a reservoir carrying a wash liquid, a layer of floatable material floating on said wash liquid and a drying chamber positioned to receive washed gases, a funnel immersed in said reservoir having an upwardly facing rim disposed in said reservoir below the level of floatable material, means inducing a flow of liquid into said funnel including a nozzle disposed to direct a spray above said funnel, a pipe connected to the lower end of the funnel to receive the liquid from said funnel and to discharge the same beyond said drying chamber, wherein said funnel and nozzle are permanently mounted for predetermined, transverse angular movement in unison across said reservoir.
Claim 2
Dependent Claim 116 words
In a gas cleaning apparatus including a reservoir carrying a wash liquid, a layer of floatable material floating on said wash liquid and a drying chamber positioned to receive washed gases, a funnel immersed in said reservoir having an upwardly facing rim disposed in said reservoir below the level of floatable material, means inducing a flow of liquid into said funnel including a nozzle disposed to direct a spray above said funnel, a pipe connected to the lower end of the funnel to receive the liquid from said funnel and to discharge the same beyond said drying chamber, wherein said funnel and nozzle are permanently mounted for predetermined, transverse angular movement in unison across said reservoir.
Claim 3
Dependent Claim 27 words
Apparatus as set forth in claim 1 wherein the nozzle is disposed to direct a spray of liquid onto the surface of said liquid above said funnel.
Claim 4
Dependent Claim 24 words
Apparatus as set forth in claim 1 including a second nozzle disposed in said funnel to direct a jet of liquid toward said pipe.
Claim 5
Dependent Claim 17 words
Apparatus as set forth in claim 1 in which said funnel has an inwardly directed rim portion.
Claim 6
Dependent Claim 33 words
Apparatus as set forth in claim 1 in which a second nozzle is disposed in said pipe to direct a liquid jet into said pipe to thereby induce the flow of material therethrough.
Claim 7
Dependent Claim 24 words
Apparatus as set forth in claim 1 including a plurality of funnels which are stacked in spaced relationship to provide openings at different elevations.
