Abstract: An anode comprises one or more sheets of expanded zinc mesh. The thickness and mesh size of the expanded zinc mesh may vary. A single sheet of zinc mesh may be coiled, forming continuous electrical contact with itself. Alternatively, a single sheet of zinc mesh may be folded into layers, each layer in electrical contact with its adjacent layers. A third alternative is the use of two or more sheets of zinc mesh, layered on top of each other so that each layer is in electrical contact with adjacent layers. These zinc mesh anodes are combined with a casing, a cathode, an electrolyte solution, and a separator between the cathode and anode to manufacture electrochemical cells.

Abstract: A bullet, bullet jacket, and method of making the bullet and bullet jacket. The bullet jacket comprises a predominantly copper outer shell and a predominantly zinc lining. The bullet comprises the bullet jacket and a bullet core. The bullet jacket is made by forming a predominantly copper sheet and a predominantly zinc sheet. The two sheets are then adhered to one another by cladding or roll bonding, and shaped such that they can fully encase a bullet core. The bullet is then made by using conventional means to seat and enclose the bullet core within the bullet jacket of the present invention.

Abstract: The present invention provides an apparatus for reducing the allowed output current from an electrical device such as a high output capacity vehicle alternator in response to a sensed over temperature condition. In one embodiment, a thermistor is attached to the housing of an alternator to provide temperature sensing capability. As temperature exceeds a temperature set point established by a resistor bridge, op-amps, in combination with a power FET in series with the alternator field windings, act to reduce the allowed current output from the alternator in proportion to the extent the set point temperature has been exceeded. As the alternator temperature returns to below the set point, the output current restriction is reduced such that the allowed current flow is maximized without exceeding the temperature set point.

Abstract: The present invention comprises a textured separator plate having specific desirable surface characteristics and method of manufacture of said plate. The separator plate in one embodiment is fashioned from steel which is textured by cold working, for example, by a laser-matte rolling process. Preferably, the surface texture is a repeatable bi-dimensional pattern exhibiting a surface profile which is plateau-like in appearance, the texture comprising a regular pattern of curvilinear recesses defining island-like features.

Abstract: A felt provides a uniform paper-supporting surface having good water storage and water release properties. These qualities are effected by a bat including one or more layers of fine fibers being needled onto a base containing perforations and cavities. The free surfaces of the bat fibers needled into the cavities are reduced in a special production step following the needling operation.
