Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
157 words
A distilling apparatus, comprising: a. a chamber; b. an evaporator means within said chamber for receiving and evaporating solvent from a solvent-containing liquid and, in operation, causing said solvent to evaporate, leaving a foaming liquid residue; said evaporator means comprising a container extending longitudinally in the vertical direction, said container being open at its upper end to permit exiting of said foaming liquid and closed at its lower end and being embraced by a steam jacket; c. means for introducing a solvent-containing liquid into said container comprising a conduit suspended vertically in said container, said conduit terminating in an open end spaced from the closed end of the container so that fluid passing through said conduit will fall by gravity to said closed end; d. vapor collection means opening into said chamber for collecting the solvent vapor produced; and e. means juxtaposed with said evaporator means to prevent said foaming liquid from entering said vapor collection means.
Claim 2
Dependent Claim
157 words
A distilling apparatus, comprising: a. a chamber; b. an evaporator means within said chamber for receiving and evaporating solvent from a solvent-containing liquid and, in operation, causing said solvent to evaporate, leaving a foaming liquid residue; said evaporator means comprising a container extending longitudinally in the vertical direction, said container being open at its upper end to permit exiting of said foaming liquid and closed at its lower end and being embraced by a steam jacket; c. means for introducing a solvent-containing liquid into said container comprising a conduit suspended vertically in said container, said conduit terminating in an open end spaced from the closed end of the container so that fluid passing through said conduit will fall by gravity to said closed end; d. vapor collection means opening into said chamber for collecting the solvent vapor produced; and e. means juxtaposed with said evaporator means to prevent said foaming liquid from entering said vapor collection means.
Claim 3
Dependent Claim
41 words
The invention of claim 1 wherein said steam jacket comprises a substantially cylindrical body rising from a base which extends radially outwardly so as to be contacted by the foaming liquid which overflows said evaporator means and falls thereon by gravity.
