Title: Copper electrorefining bath - comprising several units with hollow connecting walls
Inventor: SCHAB D
IPC: C25C7/00
Filed: 1971-08-12
Abstract: A copper electro-refining bath comprises several bath units between which are disposed double-partition separating walls closed above the below and connected solidly or detachably with the bath, having over the whole width one or more ranges of openings which are situated on one side at the level of the lower edge of the cathode and/or a little higher, and on the other side at the level of the electrolyte and/or a little lower; the separating walls at the entry of the electrolyte to the first bath-unit and at the exit from the last unit can be double- or single-partitions. The electrodes can be placed directly on the walls or on special corrosion-resistant supports. The object is to allow more intensive electrolysis, by forming a regular and forced mixing of the admitted electrolyte, while avoiding a turbulence of the anode muds, creating conditions favourable to the sedimentation of the muds, and preventing electrode bipolarity.

Title: Cascade development station having a roughened development plate for enhancing developer mixture turbulence
Inventor: GENTHE JAMES E
IPC: G03G15/08
Filed: 1974-12-13
Granted: 1979-02-06
Abstract: ABSTRACT OF THE DISCLOSURE           A special inexpensive development electrode within a cascade development station is positioned closely adjacent to a xerographic drum.  The plate is roughened by producing protuber-ances thereon forming a waffle-like or diamond-shaped knurled pattern for impeding free fall of the development powder and for causing the development mixture to have considerable motion radially with respect to the drum, which in turn greatly increases the number of development events, increases the quantity of toner made available within the development station for a fixed supply of development mixture to increase the copy output rate of the machine and which more effectively scavenges toner on background portions of the drum and prevents buildup of toner on the develop-ment plate.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of making a dynamically balanced V-grooved sheet metal pulley from a flat sheet metal disc by roller spinning and splitting tools.  The disc is provided with a central hole for mounting the disc on rotating die means between first head-stock and tailstock die form assemblies of a spinning machine. The spinning tool presses the disc against an end of a headstock die form and moves generally radially outwardly pressing a portion of the die against the end of the die to provide a circular hub wall.  The spinning tool then moves in a series of passes along the headstock die form thereby rolling, forming and ironing the rotating outer metal portions of the disc against the die and forming an axially extending cylindrical side wall terminating in a radially outwardly extending annular flange of a cup-shaped stage blank.  The flange then is trimmed to a predetermined length and to form a peripheral axially extending edge on the flange.  The cup-shaped blank then is transferred to and clamped between second headstock and tailstock die form assemblies.  The clamped cup-shaped blank is rotated and splitting roll means splits the peripheral edge of the annular flange by exerting radial pressure thereon to form a rough V-shaped groove in the flange.  Finishing roll means then move radially into the rough V-shaped groove and forms a finished V-shaped pulley groove. Alternately, the spinning tool may thin the metal in the cylin-drical side wall during the forming of the cup-shaped stage blank, whereby the finished pulley has a thicker reinforced circular end wall for receiving a hub than the thinned cylindrical side wall.
