Abstract
Abstract Apparatus for electrolysis by projection for deposit of or removal of a metal material on parts which are at least partially electrically conducting, characterized by the fact that it comprises at least one jet fed by a pump and which continuously projects the electrolyte onto a defined area on the surface of the parts, these parts being placed on a support with a device insuring their electrical connection to a direct current polarity while the other polarity is connected to an electrode positioned in the hydraulic circuit upstream of the jet.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
192 words
Electrolysis apparatus for deposition or removal of a metal on at least partially electrically conductive parts comprising a closed chamber, means for conveying flat parts through said chamber along a pre-determined path, means for projecting a sheet of electrolyte transversely of and toward said path so that the sheet of electrolyte impinges on the articles moving along the path, electrode means upstream of said projecting means for electrical connection to one side of an energizing circuit, means for connecting said flat parts to the other side of the energizing circuit during travel of the parts through said chamber, additional chambers adjacent to said first mentioned closed chamber, and wherein an exit opening of one chamber is the inlet opening of the next adjacent chamber, seal means between said chambers for isolating said chambers from each other while permitting the passage of said flat parts through said chambers, said seal means permitting maintenance of a neutral gas pressure within said chambers to prevent entrance of atmospheric air into said chambers, and means in said additional chambers for further treating said parts by projecting a liquid sheet toward said parts in said additional chambers.

Claim 3
Dependent Claim
25 words
Apparatus according to claim 1 wherein said means for electrical connecting to said parts comprises electrical brush means engaging electrically conductive areas of said parts.
Claim 4
Dependent Claim
27 words
Apparatus according to claim 1 wherein said means for projecting a sheet of electrolyte comprises means for directing parallel sheets of electrolyte toward surfaces of said parts.
Claim 5
Dependent Claim
175 words
Electrolysis apparatus for deposition or removal of a metal on at least partially electrically conductive parts, said parts being generally flat and moving continuously along a substantially horizontal path in a substantially horizontal position, comprising a closed chamber with inlet and exit openings; means in the chamber for projecting a sheet of electrolyte toward said parts transversely to said horizontal path; electrode means upstream of said projecting means and electrical connections between said electrode means and said parts; at least one support roller located under and engaging said parts for supporting them; at least a pair of driving rollers engaging both faces of said parts for moving them along said horizontal path; said support and driving rollers being located along said path with said support roller on one side of said projected sheet of electrolyte, and said driving rollers on the other side of said projected sheet of electrolyte; and sealing means including a pair of sealing lips engaging both sides of said parts, said sealing means being located at said openings of said chamber.
