Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
103 words
An apparatus for drawing a desired sample fraction from a gaseous effluent mixture comprising means having a substantially columnar passageway for receiving said effluent, said columnar passageway having an inlet and an outlet, said effluent being received at said inlet, means for providing a serpentine pathway for said effluent, said serpentine pathway providing means being located within said columnar passageway between said inlet and said outlet, means for tapping said desired sample fraction from said outlet, and means for maintaining a desired temperature in a region adjacent said sample outlet tap, said desired temperature being substantially equivalent to the desired fraction boiling point.
Claim 2
Independent Claim
103 words
An apparatus for drawing a desired sample fraction from a gaseous effluent mixture comprising means having a substantially columnar passageway for receiving said effluent, said columnar passageway having an inlet and an outlet, said effluent being received at said inlet, means for providing a serpentine pathway for said effluent, said serpentine pathway providing means being located within said columnar passageway between said inlet and said outlet, means for tapping said desired sample fraction from said outlet, and means for maintaining a desired temperature in a region adjacent said sample outlet tap, said desired temperature being substantially equivalent to the desired fraction boiling point.
Claim 3
Dependent Claim
41 words
An apparatus in accordance with claim 1 wherein said temperature maintaining means includes means for varying said temperature to a different value to obtain a different desired fraction, said different value being substantially equivalent to the different desired fraction boiling point.
Claim 4
Dependent Claim
47 words
An apparatus in accordance with claim 1 wherein said temperature maintaining means includes a sleeve-like means having an inlet and an outlet, said sleeve-like means substantially surrounding said columnar passageway, a thermoregulating fluid being contained within said sleeve-like means and flowing therethrough for maintaining said desired temperature.
Claim 5
Dependent Claim
43 words
An apparatus in accordance with claim 3 wherein said temperature maintaining means further includes temperature sensing and controlling means for sensing the temperature in said region and controlling the flow of said thermoregulating fluid within said sleeve-like means to maintain said desired temperature.
Claim 6
Dependent Claim
28 words
An apparatus in accordance with claim 1 wherein said tapping means includes a plurality of outlet taps for contemporaneously tapping a plurality of samples of said desired fraction.
Claim 7
Dependent Claim
28 words
An apparatus in accordance with claim 3 wherein said tapping means includes a plurality of outlet taps for contemporaneously tapping a plurality of samples of said desired fraction.
Claim 8
Dependent Claim
56 words
An apparatus in accordance with claim 1 wherein said effluent is from a virgin naphtha cracking furnace, and said temperature maintaining means maintains said desired temperature in a range substantially between 105* and 115* C whereby said desired sample includes a gaseous fraction including hydrogen through hydrocarbons having four carbon atoms, a gasoline fraction and water.
Claim 9
Dependent Claim
52 words
An apparatus in accordance with claim 1 wherein said effluent is from a virgin naphtha cracking furnace, and said temperature maintaining means maintains said desired temperature in a range substantially between 40* and 50* C whereby said desired sample includes a gaseous fraction including hydrocarbons having from one to four carbon atoms.
