Abstract: Electroformed shield having a first part and a second part, the first part having a leg portion and a leading portion and the second part having a leg portion and a leading portion. The leading portions being bonded to form a wedge and a saddle area between the leg portion. The saddle portion accommodating a blade useful in a low-pressure fan for a turbofan jet engine.

Abstract: An infrared cold shield comprises a side wall, a top wall and at least one baffle extending across the interior of the cold shield. The top wall and baffles comprise aligned apertures. The cold shield is preferably made by securing one or more metal foil disks and aluminum mandrel segments in an alternating stacked arrangement wherein the outer edges of the metal foil disks are exposed. The assembly is then electroplated to deposit a layer of metal over the side surfaces of the mandrel segments and to capture and bond with the exposed edges of the metal foil sections. The mandrel segments are then dissolved.

Abstract: A method of forming a xerographic belt substrate is provided in which the conductive metal backing is an endless flexible seamless band of nickel. The substrate band is made by electroforming, using a cylindrical mandrel of aluminum with a thin coating of stainless steel, passivated nickel or chromium and an electroplating nickel solution. During the electroforming operation the mandrel is rotated about an anode disposed in the electroplating solution.

Abstract: A cylindrically shaped hollow mandrel is disclosed which is suitable in an electroforming process used for the production of an endless seamless nickel xerographic belt. The mandrel set forth comprises a metal core member with a thin removable metal sleeve having a thickness between about 10 and 60 mils which is fitted over said core member to provide a surface for electroforming of the nickel belt. Mandrels disclosed in the present invention have the advantage of a longer lifetime of use in a continuous electroforming process because of the replaceable nature of the metal sleeve.
