Abstract
Abstract A liquid and aerosol collecting device where liquid is disposed on one flat surface of a liquid receiving member that is caused to be spun so that at least a portion of the liquid flows off an edge of the member. Means for intercepting this portion of the liquid is disposed around the liquid receiving member. The peripheral edge of the intercepting means is formed into a capillary-type passage which terminates in a cup shaped ring for temporarily storing the liquid as it is emitted from said passage. A means for collecting the liquid is also provided in conjunction with said cup shaped ring. Any aerosol which may be generated by the spinning, is caused to be intercepted by the peripheral intercepting means and recombined with the liquid that is being collected.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
173 words
A liquid and aerosol collecting device comprising a dish-like member having sloped walls and a horizontally extending lip along the outer peripheral edge of said sloped walls, said dish-like member being adapted to accommodate and support a liquid receiving member having at least one flat surface adapted to receive a liquid thereon, a circular member having a horizontally extending annular portion disposed closely adjacent said lip so as to define a passage between one surface of said circular member and said lip and a depending portion encoMpassing said lip, means for spinning said dish-like member and said liquid receiving member together about an axis substantially perpendicular to said one flat surface so that at least a portion of any liquid disposed on said one flat surface is caused to flow off an edge of said member, at least a portion of any aerosol of said liquid that is formed being recombined with said portion of said liquid, and means for collecting said liquid operatively associated with said dish-like member and said circular member.
Claim 2
Dependent Claim
173 words
A liquid and aerosol collecting device comprising a dish-like member having sloped walls and a horizontally extending lip along the outer peripheral edge of said sloped walls, said dish-like member being adapted to accommodate and support a liquid receiving member having at least one flat surface adapted to receive a liquid thereon, a circular member having a horizontally extending annular portion disposed closely adjacent said lip so as to define a passage between one surface of said circular member and said lip and a depending portion encoMpassing said lip, means for spinning said dish-like member and said liquid receiving member together about an axis substantially perpendicular to said one flat surface so that at least a portion of any liquid disposed on said one flat surface is caused to flow off an edge of said member, at least a portion of any aerosol of said liquid that is formed being recombined with said portion of said liquid, and means for collecting said liquid operatively associated with said dish-like member and said circular member.
Claim 3
Dependent Claim
173 words
A liquid and aerosol collecting device comprising a dish-like member having sloped walls and a horizontally extending lip along the outer peripheral edge of said sloped walls, said dish-like member being adapted to accommodate and support a liquid receiving member having at least one flat surface adapted to receive a liquid thereon, a circular member having a horizontally extending annular portion disposed closely adjacent said lip so as to define a passage between one surface of said circular member and said lip and a depending portion encoMpassing said lip, means for spinning said dish-like member and said liquid receiving member together about an axis substantially perpendicular to said one flat surface so that at least a portion of any liquid disposed on said one flat surface is caused to flow off an edge of said member, at least a portion of any aerosol of said liquid that is formed being recombined with said portion of said liquid, and means for collecting said liquid operatively associated with said dish-like member and said circular member.
Claim 4
Dependent Claim
173 words
A liquid and aerosol collecting device comprising a dish-like member having sloped walls and a horizontally extending lip along the outer peripheral edge of said sloped walls, said dish-like member being adapted to accommodate and support a liquid receiving member having at least one flat surface adapted to receive a liquid thereon, a circular member having a horizontally extending annular portion disposed closely adjacent said lip so as to define a passage between one surface of said circular member and said lip and a depending portion encoMpassing said lip, means for spinning said dish-like member and said liquid receiving member together about an axis substantially perpendicular to said one flat surface so that at least a portion of any liquid disposed on said one flat surface is caused to flow off an edge of said member, at least a portion of any aerosol of said liquid that is formed being recombined with said portion of said liquid, and means for collecting said liquid operatively associated with said dish-like member and said circular member.
Claim 5
Dependent Claim
16 words
The liquid and aerosol collecting device of claim 1 wherein said passage is a capillary-like passage.
Claim 6
Dependent Claim
38 words
The liquid and aerosol collecting device of claim 1 wherein said depending portion comprises a cup shaped ring disposed at the outer peripheral edge of said circular member so as to receive any liquid emitted from said passage.
Claim 7
Dependent Claim
54 words
The liquid and aerosol collecting device of claim 3 wherein said means for collecting liquid comprises a second cup shaped ring and a liquid absorbent material disposed therein, said first cup shaped ring being disposed such that said liquid ultimately drains into said second cup shaped ring and is absorbed by said absorbent material.
