Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
89 words
Apparatus transferring a substance from a first to a second liquid stream, comprising: means flowing said first stream from a source to a first station and depositing it upon a conveyor movable from said first station to a second station, means to move said conveyor, means flowing said second stream to said second station to pick up said substance, means to flow said deposited first stream along at least a portion of the conveyor from said first station toward said second station, and means to actuate said conveyor-moving means.
Claim 2
Dependent Claim
89 words
Apparatus transferring a substance from a first to a second liquid stream, comprising: means flowing said first stream from a source to a first station and depositing it upon a conveyor movable from said first station to a second station, means to move said conveyor, means flowing said second stream to said second station to pick up said substance, means to flow said deposited first stream along at least a portion of the conveyor from said first station toward said second station, and means to actuate said conveyor-moving means.
Claim 3
Dependent Claim
28 words
Apparatus as defined in claim 1, wherein: said substance is a solute, said means flowing said deposited first stream comprising an evaporator tube through which said conveyor moves.
Claim 4
Dependent Claim
26 words
Apparatus as defined in claim 1, wherein: said substance is a liquid sample, and further including analysis means downstream from said second station analyzing said sample.
Claim 5
Dependent Claim
28 words
Apparatus as defined in claim 1, wherein: said conveyor is structured of an elongated element having a uniform relatively smooth longitudinal exterior on which said deposit is made.
Claim 6
Dependent Claim
25 words
Apparatus as defined in claim 2, wherein: said evaporator tube is funnel-shaped and funnels a drying gas therethrough to a vacuum outlet of said tube.
Claim 7
Dependent Claim
31 words
Apparatus as defined in claim 2, wherein: said evaporator tube is of T form, and a solvent of said solute is evaporated to dryness prior to arrival at said second station.
Claim 8
Dependent Claim
19 words
Apparatus as defined in claim 4, wherein: said elongated element has a periphery which in cross section is circular.
Claim 9
Independent Claim
83 words
A method of transferring a substance from a first to a second liquid stream, comprising: flowing said first stream from a source to a first station and depositing it upon a conveyor movable from said first station to a second station, flowing said second stream to said second station to pick up said substance, flowing said deposited first stream along at least a portion of the conveyor from said first station toward said second station, and moving the conveyor to said second station.
Claim 10
Independent Claim
83 words
A method of transferring a substance from a first to a second liquid stream, comprising: flowing said first stream from a source to a first station and depositing it upon a conveyor movable from said first station to a second station, flowing said second stream to said second station to pick up said substance, flowing said deposited first stream along at least a portion of the conveyor from said first station toward said second station, and moving the conveyor to said second station.
Claim 11
Dependent Claim
30 words
A method as defined in claim 8, wherein: said substance is a solute in a solvent, and evaporating said solvent to dryness while moving said conveyor to said second station.
Claim 12
Dependent Claim
25 words
A method as defined in claim 8, wherein: said substance is a liquid sample, and further including analyzing said sample downstream from said second station.
Claim 13
Dependent Claim
32 words
A method as defined in claim 8, wherein said flowing of said deposited first stream on said conveyor comprises drawing said stream along a portion of said conveyor as a sheath stream.
Claim 14
Dependent Claim
34 words
A method as defined in claim 8, wherein: the volumetric flow of said first and second streams is varied one to the other to change the concentration of said substance in said second stream.
Claim 15
Dependent Claim
22 words
A method as defined in claim 9, wherein: said evaporating step comprises funneling a drying gas along a portion of said conveyor.
Claim 16
Dependent Claim
23 words
A method as defined in claim 9, wherein: said solute is evaporated to dryness while said conveyor is moving to said second station.
