Abstract
Abstract This invention is a compact gas purifier useful as a home air purifier. Gas scrubber action is achieved in a specially shaped bowl partially filled with liquid. A central rotor drives the liquid by centrifugal force out and up the wall of the bowl to a re-entrant rim which directs the liquid back into the central region of the bowl in a spray. Gas to be purified is drawn in over the rim of the bowl, down through the spray of liquid and up out through a central cylindrical tube which surrounds the top of the rotor.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
171 words
An improved gas purifier comprising: a A bowl with a reentrant outer rim, said rim pointing in and down toward the central region of said bowl b A liquid contained in said bowl c A rotor in the center of said bowl d Means for spinning said rotor with such force that said liquid in said bowl is carried outward, up the wall of said bowl, around said reentrant rim and is hurled back down toward the central region of said bowl to be recycled, e A hollow tube like structure opening into said central region of said bowl through which gas may flow out of said central region of said bowl allowing additional gas to flow into said central region of said bowl past said reentrant rim of said bowl through said liquid being hurled downward and inward from said rim, f Means for drawing gas into said bowl between said rim and said tube and out through said tube so as to cause gas to flow through said purifier.
Claim 2
Dependent Claim
171 words
An improved gas purifier comprising: a A bowl with a reentrant outer rim, said rim pointing in and down toward the central region of said bowl b A liquid contained in said bowl c A rotor in the center of said bowl d Means for spinning said rotor with such force that said liquid in said bowl is carried outward, up the wall of said bowl, around said reentrant rim and is hurled back down toward the central region of said bowl to be recycled, e A hollow tube like structure opening into said central region of said bowl through which gas may flow out of said central region of said bowl allowing additional gas to flow into said central region of said bowl past said reentrant rim of said bowl through said liquid being hurled downward and inward from said rim, f Means for drawing gas into said bowl between said rim and said tube and out through said tube so as to cause gas to flow through said purifier.
Claim 3
Dependent Claim
92 words
The improved gas purifier claimed in claim 1 wherein the tube by which said gas is drawn out of said bowl is a hollow vertical cylinder above the central region of said bowl, the bottom of said cylinder extending down into said bowl such that said liquid hurled inward from said reentrant rim strikes said cylinder and is deflected back outward and downward, said gas entering into said central region of said bowl between the rim of said bowl and said hollow central cylinder and exiting up through said hollow central cylinder.
Claim 4
Dependent Claim
55 words
A gas purifier as claimed in claim 2 wherein said means for drawing gas into said bowl comprises a motor and blower located in said hollow vertical cylinder above said bowl said motor driving said blower and said blower drawing gas into said bowl between said rim and said cylinder and out through said cylinder.
Claim 5
Dependent Claim
19 words
The improved gas purifier claimed in claim 1 wherein said liquid is a solution of water and ethylene glycol.
Claim 6
Dependent Claim
27 words
The improved gas purifier claimed in claim 1 wherein said liquid is a solution of water and ethylene glycol, and said liquid also contains disinfectants and deodorants.
Claim 7
Dependent Claim
68 words
The improved gas purifier as claimed in claim 1 further comprising, a float in said bowl which floats on said liquid, an electric light external to said bowl controlled by an electric switch external to said bowl, means by which said switch is connected to said float so as to cause said switch to be activated, turning on said light, when said float falls below some preset level.
