Abstract
Abstract An electrolytic cell comprising an outer conduit electrode structure and an inner electrode structure comprising a series of sheet-like elements extending longitudinally within the outer electrode structure. The cell is adapted to have a fluid electrolyte flow through it along the series of inner electrode elements. Each sheet-like element is curved to turn the direction of fluid flow by being arranged in alternating right- and lefthanded curvature groups (a group consisting of one or more elements). As a result, each particle of fluid is moved is a programmed manner toward and away from each electrode as it flows through the cell. Embodiments are disclosed in which the spacing between the inner and outer electrode structure is tapered by tapering the dimensions of either of them. Either of the electrode structures may be subdivided electrically and connected to different electrical potentials to provide flexibility in adapting the cell to a wide variety of operations.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
96 words
An electrolytic cell structure comprising: a. a conduit through which a fluid electrolyte is adapted to flow; b. an inner electrode structure comprising a plurality of curved sheet-like electrically conductive elements extending longitudinally within said conduit, each of said elements having a curvature to impart a transverse rotational component of flow to said electrolyte, said elements being arranged in alternating right- and left-handed curvature groups whereby said transverse rotational component is alternately reversed; and c. an outer electrode structure, within said conduit, insulated from and surrounding said inner electrode along a substantial portion of its length.
Claim 2
Dependent Claim
