Analytical electroplating cell

Claim 1

THE METHOD OF SIMULTANEOUSLY DETERMINING THE COMPARATIVE APPEARANCE OF THE ELECTRODEPOSIT OBTAINABLE FROM THE SAME PLATING BATH UNDER DIFFERING CURRENT DENSITIES AND IN A SINGLE PLATING OPERATION, WHICH METHOD COMPRISES PASSING AN ELECTRIC CURRENT FROM AN ANODE THROUGH A CONFINED BODY OF THE PLATING BATH TO A CATHODE WHILE THE BATH IS CONFINED AT ITS BOTTOM AND CONFINED ON TWO SIDES BY INTERSECTING VERTICAL FLAT STRAIGHT BOUNDARY PLANES THAT FORM AN ACUTE INCLUDED ANGLE AND ARE POSITIONED RELATIVE TO ONE ANOTHER SO THAT ON E SUCH SIDE IS REPRESENTED BY THE ANALYTICAL EQUATION Y EQUALS ZERO WHILE THE OTHER OF THEM CORRESPONDS TOTHE EQUATION X EQUALS Y; AND THEN HAVING ITS CONFINEMENT COMPLETEC ON TWO OTHER SIDES BY A CURVED BOUNDARY PLANE FOR EACH OF THEM, SUCH THAT BOTH OF THESE TWO CURVED BOUNDARY PLANES ARE HYPERBOLICALLY CURVED IN HORIZONTAL CROSS-SECTION WITH THEIR INNER SURFACES CORRESPONDING RESPECTIVELY TO THE EQUATIONS X2-Y2 EQUALS L2, AND XY EQUALS ONE-HALF OF R2L2, WHEREIN L IS THE LENGTH OF ONE OF THE TWO STRAIGHT PLANES, AND R IS THE RATIO BETWEEN THE RESPECTIVE LENGTHS OF THE TWO STRAIGHT SIDES; AND THE TWO CURVED PLANES ARE SEGMENTS OF HYPERBOLIC CYLINDERS AND ORHTOGONAL TO EACH OTHER AT THEIR JUNCTION AND EACH OF THEM IS ORTHOGONAL TO ITS RESPECTIVELY ADJACENT STRAIGHT PLANES AND ASYMPTOTIC TO THE OTHER; ONE OF THE ELECTRODES PROVIDING ONE OF THE STRAIGHT PLANES, AND THE OTHER ELECTRODE PROVIDING THE CURVED PLANE POSITIONED OPPOSITE TO THE FIRST ELECTRODE.

Claim 2

THE METHOD OF SIMULTANEOUSLY DETERMINING THE COMPARATIVE APPEARANCE OF THE ELECTRODEPOSIT OBTAINABLE FROM THE SAME PLATING BATH UNDER DIFFERING CURRENT DENSITIES AND IN A SINGLE PLATING OPERATION, WHICH METHOD COMPRISES PASSING AN ELECTRIC CURRENT FROM AN ANODE THROUGH A CONFINED BODY OF THE PLATING BATH TO A CATHODE WHILE THE BATH IS CONFINED AT ITS BOTTOM AND CONFINED ON TWO SIDES BY INTERSECTING VERTICAL FLAT STRAIGHT BOUNDARY PLANES THAT FORM AN ACUTE INCLUDED ANGLE AND ARE POSITIONED RELATIVE TO ONE ANOTHER SO THAT ON E SUCH SIDE IS REPRESENTED BY THE ANALYTICAL EQUATION Y EQUALS ZERO WHILE THE OTHER OF THEM CORRESPONDS TOTHE EQUATION X EQUALS Y; AND THEN HAVING ITS CONFINEMENT COMPLETEC ON TWO OTHER SIDES BY A CURVED BOUNDARY PLANE FOR EACH OF THEM, SUCH THAT BOTH OF THESE TWO CURVED BOUNDARY PLANES ARE HYPERBOLICALLY CURVED IN HORIZONTAL CROSS-SECTION WITH THEIR INNER SURFACES CORRESPONDING RESPECTIVELY TO THE EQUATIONS X2-Y2 EQUALS L2, AND XY EQUALS ONE-HALF OF R2L2, WHEREIN L IS THE LENGTH OF ONE OF THE TWO STRAIGHT PLANES, AND R IS THE RATIO BETWEEN THE RESPECTIVE LENGTHS OF THE TWO STRAIGHT SIDES; AND THE TWO CURVED PLANES ARE SEGMENTS OF HYPERBOLIC CYLINDERS AND ORHTOGONAL TO EACH OTHER AT THEIR JUNCTION AND EACH OF THEM IS ORTHOGONAL TO ITS RESPECTIVELY ADJACENT STRAIGHT PLANES AND ASYMPTOTIC TO THE OTHER; ONE OF THE ELECTRODES PROVIDING ONE OF THE STRAIGHT PLANES, AND THE OTHER ELECTRODE PROVIDING THE CURVED PLANE POSITIONED OPPOSITE TO THE FIRST ELECTRODE.
