Abstract: A pickle line assembly is provided having a roll tank, a pickle tank, and an expansion seal. The roll tank includes a front and rear face that are angled towards one another at the upper end. The pickle tank includes front and rear openings, which can be brought into registration with an opening in the front face and rear face of the roll tank. Expansion seals are configured to surround a perimeter of the pickle tank substantially near the front and rear openings, and are angled at approximately the same angle as the front and rear face of the roll tank. The expansion seal encloses the path between the pickle tank and roll tank, and the tilt angle of the front and rear face of the roll tank allow the pickle tank to be vertically raised and lowered into position without interference.

Abstract: A photoreceptor aluminum alloy substrate is prepared with specific roughness characteristics and an oxide layer for use in multi-layered electrophotographic photoreceptor. A photoreceptor substrate, or drum, is placed in a lathe and turned using a polycrystalline tool to achieve specific roughness characteristics. A oxide layer is then allowed to form on the roughened photoreceptor substrate. The roughened surface of the photoreceptor aluminum alloy substrate in conjunction with the oxide layer on the roughed surface reduces variances in surface energy across the photoreceptor substrate, and eliminates, or greatly reduces, a number of Tiger Stripe and Tiger Tail defects that may occur in an undercoat layer subsequently applied to the roughened photoreceptor substrate. The approach eliminates the need for wet honing and thereby significantly reduces the complexity and cost of fabricating a multi-layered electrophotographic photoreceptor.

Abstract: A mounting apparatus for mounting a hollow work-piece on a machine includes a circumferential groove formed into an outer surface of a cylindrical supporting fixture of the machine, a dampening plug assembly for positioning inside the hollow workpiece adjacent the cylindrical supporting fixture, and an end pressure reducing device for mounting within the circumferential groove for centrifugally supporting and enabling the reduction of machining-induced pressure from the end of the hollow workpiece.
