Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
135 words
In combination, a plurality of convolutely wound lengths of anode material formed of rod or wire, defining a plurality of coils, said rod having a cross-section defining a predetermined configuration in at least a portion of the periphery of the cross-section, said rod being wound so that said predetermined configuration of said cross-section of each convolution of each said coil faces radially outwardly, each said coil being generally planar or flat, and a perforate anode basket having an elongate loading opening, said opening having a width and a length, the outer diameter of each said coil being dimensioned so that it is greater than the width of the opening but less than the length thereof, whereby said coils stack freely in a predetermined pattern within the basket when the coils are fed through the opening.
Claim 2
Dependent Claim
135 words
In combination, a plurality of convolutely wound lengths of anode material formed of rod or wire, defining a plurality of coils, said rod having a cross-section defining a predetermined configuration in at least a portion of the periphery of the cross-section, said rod being wound so that said predetermined configuration of said cross-section of each convolution of each said coil faces radially outwardly, each said coil being generally planar or flat, and a perforate anode basket having an elongate loading opening, said opening having a width and a length, the outer diameter of each said coil being dimensioned so that it is greater than the width of the opening but less than the length thereof, whereby said coils stack freely in a predetermined pattern within the basket when the coils are fed through the opening.
Claim 3
Dependent Claim
34 words
The combination of claim 1 where the rod is fabricated of anode material such as copper, zinc, cadmium or nickel and the basket is fabricated of material which is not soluble in the electrolyte.
Claim 4
Dependent Claim
43 words
The combination of claim 1 where the loading opening of said basket generally defines an elliptic figure having a major and a minor axis, the outer diameter of each said coil being greater than said minor axis but less than said major axis.
Claim 5
Dependent Claim
33 words
The combination of claim 1 in which said predetermined configuration of that portion of the periphery of the cross-section of the rod which faces radially outwardly subtends an angle of less than 180°.
Claim 6
Dependent Claim
13 words
The combination of claim 1 in which the loading opening defines a rectangle.
Claim 7
Dependent Claim
37 words
The combination of claim 1 where the loading opening of said basket generally defines a parallelogram, the outer diameter of each said coil being greater than the width of said parallelogram but less than the length thereof.
Claim 8
Dependent Claim
28 words
The combination of claim 1 in which said predetermined configuration of the portion of the periphery of the cross-section of the rod which faces radially outwardly is arcuate.
Claim 9
Dependent Claim
47 words
The basket of claim 1 wherein the horizontal cross-section of said basket is a parallelogram having a length and a width, said outer diameter of each said coil being greater than the width of said parallelogram and said length of said parallelogram is greater than said diameter.
Claim 10
Dependent Claim
18 words
The combination of claim 1 wherein said predetermined configuration of said cross-section of each convolution is a semicircle.
Claim 11
Independent Claim
139 words
A method of packaging a plurality of anodic units within an anode basket comprising the steps of: providing an anode basket having a loading opening, said opening having a width and a length, providing a rod of anodic material, said rod having a cross-section defining a nose or share portion, winding said rod convolutely into a coil so that said nose portion faces radially outwardly in each convolution, and so that said coil is generally planar or flat, dimensioning the outer diameter of said convolutely wound rod so that it is greater than the width of said basket opening but less than the length thereof and feeding said anodic units into the basket through said opening whereby said units, by virtue of the method of manufacture, stack within the basket in accordance with a predetermined pattern or array automatically.
Claim 12
Independent Claim
139 words
A method of packaging a plurality of anodic units within an anode basket comprising the steps of: providing an anode basket having a loading opening, said opening having a width and a length, providing a rod of anodic material, said rod having a cross-section defining a nose or share portion, winding said rod convolutely into a coil so that said nose portion faces radially outwardly in each convolution, and so that said coil is generally planar or flat, dimensioning the outer diameter of said convolutely wound rod so that it is greater than the width of said basket opening but less than the length thereof and feeding said anodic units into the basket through said opening whereby said units, by virtue of the method of manufacture, stack within the basket in accordance with a predetermined pattern or array automatically.
Claim 13
Dependent Claim
120 words
An electrolytic process for transferring corrosive anodic material from an anode to a work piece defining a cathode within a conventionally energized electrolytic bath comprising the steps of: winding anodic rod material into convolute coils of predetermined size, said rod material having a predetermined configuration in a portion of the periphery of the cross-section thereof, each said coil being planar or flat, packaging the coils within a perforate basket so that each planar coil is disposed generally vertical and generally parallel to other coils, and circulating electrolyte through said basket into contact with said coils whereby the corrosive action occurs uniformly throughout the basket by virtue of the configuration of coils and the disposition of the coils within the basket.
Claim 14
