Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
101 words
A method of making electrolytic metal foil, comprising: carrying out electrolysis by filling, with an electrolytic solution, a space defined between a cathode drum which is rotatable on a substantially horizontal axis and an anode facing and spaced from the surface of said drum, and flowing said electrolytic solution downwardly from an upper part toward a lower part of said space at a flow velocity sufficiently high that substantially all of a gas generated in said electrolytic solution during said electrolysis flows out downwardly through said space to an outlet provided in the vicinity of the lower part of said space.
Claim 2
Independent Claim
101 words
A method of making electrolytic metal foil, comprising: carrying out electrolysis by filling, with an electrolytic solution, a space defined between a cathode drum which is rotatable on a substantially horizontal axis and an anode facing and spaced from the surface of said drum, and flowing said electrolytic solution downwardly from an upper part toward a lower part of said space at a flow velocity sufficiently high that substantially all of a gas generated in said electrolytic solution during said electrolysis flows out downwardly through said space to an outlet provided in the vicinity of the lower part of said space.
Claim 3
Dependent Claim
21 words
The method of claim 1, comprising flowing said electrolytic solution downwardly at an average flow velocity of at least 50 mm/sec.
Claim 4
Independent Claim
116 words
An apparatus for making electrolytic metal foil, comprising: a cathode drum which is rotatable on a substantially horizontal axis; an anode spaced from and facing the surface of said drum so as to define a space therebetween; and means including a solution discharging outlet at lower portion of said space, for flowing an electrolytic solution downwardly in said space from an upper portion to a lower portion of said space, at a flow velocity sufficiently high that substantially all of a gas generated during the electrolysis flows downwardly in said space and such that substantially all of said gas flows downwardly and out of said space through said outlet together with said downwardly flowing electrolytic solution.
Claim 5
Independent Claim
116 words
An apparatus for making electrolytic metal foil, comprising: a cathode drum which is rotatable on a substantially horizontal axis; an anode spaced from and facing the surface of said drum so as to define a space therebetween; and means including a solution discharging outlet at lower portion of said space, for flowing an electrolytic solution downwardly in said space from an upper portion to a lower portion of said space, at a flow velocity sufficiently high that substantially all of a gas generated during the electrolysis flows downwardly in said space and such that substantially all of said gas flows downwardly and out of said space through said outlet together with said downwardly flowing electrolytic solution.
Claim 6
Dependent Claim
21 words
The apparatus of claim 3, wherein said flow velocity of said electrolytic solution is 50 mm/sec as an average flow velocity.
Claim 7
Dependent Claim
27 words
The apparatus of claim 3, wherein said solution discharging outlet comprises an electrolytic solution flow-out tube means extended downwardly for discharging said electrolytic solution from said space.
Claim 8
Dependent Claim
17 words
The apparatus of claim 5, wherein said electrolytic solution flow-out tube means comprises a solution discharging pump.
