Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
134 words
A UNIFORM PLATING CURRENT APPARATUS FOR PROVIDING A UNIFORM FLOW OF PLATING CURRENT IN AN ELECTROLYTE SOLUTION BETWEEN A PLATING RACK CARRYING A WORK PIECE TO BE PLATED THAT FORMS A CATHODE AND A QUADRANGULAR ANODE STRUCTURE, COMPRISING: TWO GENERALLY PARALLEL SURFACES OF NONCONDUCTIVE COMPOSITION POSITIONED ALONG TWO OPPOSITE SIDES OF THE ANODE SURFACE AND EXTENDING UPWARDLY FROM THE ANODE TO THE PLATING RACK AREA; AND A FIRST AND SECOND PLURALITY OF FLOW-BLADES RUNNING TRANSVERSELY BETWEEN SAID PARALLEL SURFACES AND ALONG THE REMAINING TWO EDGES OF THE ANODE STRUCTURE, SAID FIRST PLURALITY OF FLOW-BLADES SPACED ONE ABOVE THE OTHER ALONG THE DISTANCE BETWEEN THE ANODE SURFACE AND THE PLATING RACK AREA AND SAID SECOND PLURATLITY OF FLOW-BLADES SPACED ONE ABOVE THE OTHER ALONG THE DISTANCE BETWEEN THE ANODE STRUCTURE AND THE PLATING RACK AREA.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
27 words
The uniform plating current apparatus of claim 1 further characterized in that said first and second plurality of flow-blades are generally equally spaced one from the other.
Claim 4
Dependent Claim
56 words
The uniform plating current apparatus of claim 1 further characterized in that each successive flow-blade in the direction from the object to be plated to the anode structure of said first and second plurality of flow-blades is of increasing length so as to extend farther toward the opposite plurality of flow-blades and the opposite anode edge.
Claim 5
Dependent Claim
51 words
The uniform plating current apparatus of claim 1 further characterized in that the leading edges of said first and second plurality of flow-blades extending into the electrolyte solution are generally arcuately shaped so as to provide a smooth flow of the electrolyte solution past the leading edge of each flow blade.
Claim 6
Dependent Claim
21 words
The uniform plating current apparatus of claim 1 further characterized in that the work piece carries a plurality of reed blades.
Claim 7
Independent Claim
128 words
A method for providing uniform plating current flow in an electrolyte solution between an anode structure and an object to be plated which forms a cathode surface including the steps of: positioning two generally parallel surfaces of nonconductive composition along two sides of the anode structure extending upwardly from the anode to the object to be plated; and arranging a first and second plurality of flow-blades transversely between said parallel surfaces and along the remaining two edges of the anode surface, said first plurality of flow-blades spaced one above the other along the distance between the anode structure and the object to be plated and said second plurality of flow-blades spaced one above the other along the distance between the anode surface and the object to be plated.
Claim 8
Independent Claim
