Publication number: 20060257231Abstract: Galvanically protected reinforcement dowel pins and methods of producing the same. In one embodiment, the reinforcement dowel pins comprise a bar or tube, the longitudinal exposed surfaces of which are covered by a heavy gauge of a sacrificial metal, such as zinc, zinc alloy, magnesium, magnesium alloy, aluminum, or aluminum alloy. The bar or tube comprises steel, carbon steel, or other ferrous metal. The heavy gauge of sacrificial metal is applied to the ferrous metal by various processes, such as roll bonding, lock seaming, welding, die casting, flame spraying, plasma spraying, dipping, sinking, and drawing. The resulting reinforcement dowel pins resist corrosion without sacrificing structural integrity, and are reasonable in materials and manufacturing costs. These dowel pins may be installed in adjacent concrete panels using conventional methods, and therefore do not introduce additional costs in installation.Type: ApplicationFiled: May 31, 2006Publication date: November 16, 2006Applicant: Alltrista Zinc Products, L.P.

Publication number: 20060068219Abstract: Metals having a silvery-white appearance and methods of producing the same. In one embodiment, the composite material of the present invention comprises a metallic core, a first layer, and a second layer. The first layer encases the external surfaces of the metallic core and is produced by electroplating copper or copper alloy from a first bath containing copper ions. The second layer encases the first layer and is produced by electroplating white bronze from a second bath containing copper and tin ions. According to one embodiment of the method of the present invention, the first layer is electroplated on the metallic core and the second layer is electroplated on the first layer. In another embodiment of the composite material and method of the present invention, the material comprises only the metallic core and a first layer of white bronze. The resulting composite has a silvery-white appearance and does not include exposed nickel so that persons allergic to nickel metals are not affected by the composite.Type: ApplicationFiled: September 24, 2004Publication date: March 30, 2006Applicant: Alltrista Zinc Products, L.P.Inventors: Paul McDaniel, Johnny Smelcer, Randy Beets

Patent number: 6673494Abstract: 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.Type: GrantFiled: February 15, 2002Date of Patent: January 6, 2004Assignee: Alltrista Zinc Products, L.P.Inventors: Jack T. West, Jim Dyer, Albert H. Giles, Jon Headrick, Johnny Smelcer, Randy Beets

Publication number: 20030170543Abstract: The present invention comprises a method of making metallic fibers and electrodes. The metallic fibers are manufactured by milling a stock piece of material, preferably with a computer number controlled (CNC) milling machine. According to one embodiment, the length of the fibers is determined by the width of the stock material and stock material may be stacked so as to produce a number of fibers. According to another embodiment, the cutting tool comprises chip breakers which determine the length of the fibers. Zinc fibers made according to the present invention may be used to manufacture battery electrodes by compressing the fibers into the desired shape and porosity.Type: ApplicationFiled: February 26, 2002Publication date: September 11, 2003Applicant: Alltrista Zinc Products Company, L.P.Inventors: Jon W. Headrick, Lynn Payne, Johnny Smelcer, Derek Tarrant, James Dyer

Patent number: 6383657Abstract: A composite metal laminate coin planchet comprises commercially pure aluminum cladding layers metallurgically bonded to a zinc alloy core. The zinc alloy core may contain a hardening agent, such as copper or titanium, used to increase the hardness of the alloy above that of pure zinc. Trace amounts of other elements may also be present in the zinc alloy core or in the commercially pure aluminum cladding layers which do not affect their pertinent properties. The coin planchet is produced by a process comprising providing a strip or sheet of a zinc alloy core and creating a strip or sheet of composite material by metallurgically bonding commercially pure aluminum cladding layers to the zinc alloy. The coin planchets are then removed from the strip or sheet of composite material, and the remaining composite material is heated above its melting point to produce a zinc-aluminum alloy useful in die-casting.Type: GrantFiled: December 18, 2000Date of Patent: May 7, 2002Assignee: Alltrista Zinc ProductsInventor: Dennis H.
