Patent number: 7024736Abstract: Apparatus for manufacturing multi-layer metal feedstock material for stamping shaped parts eliminates the need for rolls of metal at the stamping site. Multilayer metal feedstock material is assembled from multiple rolls of metal stock, then folded in a zig zag fashion, or “Z-fold” configuration, whereby the multilayer metal assembly is stacked vertically, usually on conventional pallets, for ease of moving with a forklift or otherwise. The multilayer metal z-fold stack of material is then transported to a parts stamping operation where the material is used as it unfolds as a continuous feed to machines to produce shaped multilayer metal parts. This invention is most useful in making multilayer metal foil z-fold feedstock material and using the z-fold material as continuous feed to processes for making shaped multilayer metal foil parts. The layers may have non-metal layers of material, such as fiber, between the metal layers or on the outside of the metal layers.Type: GrantFiled: October 8, 2004Date of Patent: April 11, 2006Assignee: ATD CorporationInventors: G.

Patent number: 6991856Abstract: Reactive foils and their uses are provided as localized heat sources useful, for example, in ignition, joining and propulsion. An improved reactive foil is preferably a freestanding multilayered foil structure made up of alternating layers selected from materials that will react with one another in an exothermic and self-propagating reaction. Upon reacting, this foil supplies highly localized heat energy that may be applied, for example, to joining layers, or directly to bulk materials that are to be joined. This foil heat-source allows rapid bonding to occur at room temperature in virtually any environment (e.g., air, vacuum, water, etc.). If a joining material is used, the foil reaction will supply enough heat to melt or soften the joining material, which upon cooling will form a strong bond, joining two or more bulk materials.Type: GrantFiled: September 20, 2002Date of Patent: January 31, 2006Assignee: Johns Hopkins UniversityInventors: Timothy P. Weihs, Michael Reiss, Omar Knio, Albert Joseph Swiston, Jr., David van Heerden, Todd Hufnagel

Patent number: 6949412Abstract: A clad plate for forming an interposer for a semiconductor device which can be manufactured at low cost and has good characteristics, an interposer for a semiconductor device, and a method of manufacturing them. Copper foil materials (19, 24, 33) forming conductive layers (10, 17, 18) and nickel plating (20, 21) forming etching stopper layers (11, 12) are formed and pressed to form a clad plate (34) for forming an interposer for a semiconductor device. Thus, a clad plate (34) for forming an interposer for a semiconductor device is manufactured. The clad plate (34) is selectively etched to form a columnar conductor (17), and an insulating layer (13) is formed on the copper foil material forming a wiring layer (10). A bump (18) for connection of a semiconductor chip and the wiring layer (10) are formed on the opposite side to the side on which the columnar conductor (17) is formed. Thus, an interposer for a semiconductor device is manufactured.Type: GrantFiled: April 10, 2003Date of Patent: September 27, 2005Assignee: Toyo Kohan Co.Inventors: Kinji Saijo, Kazuo Yoshida, Hiroaki Okamoto, Shinji Ohsawa

Patent number: 6823571Abstract: Apparatus for manufacturing multi-layer metal feedstock material for stamping shaped parts eliminates the need for rolls of metal at the stamping site. Multilayer metal feedstock material is assembled from multiple rolls of metal stock, then folded in a zig zag fashion, or “Z-fold” configuration, whereby the multilayer metal assembly is stacked vertically, usually on conventional pallets, for ease of moving with a forklift or otherwise. The multilayer metal z-fold stack of material is then transported to a parts stamping operation where the material is used as it unfolds as a continuous feed to machines to produce shaped multilayer metal parts. This invention is most useful in making multilayer metal foil z-fold feedstock material and using the z-fold material as continuous feed to processes for making shaped multilayer metal foil parts. The layers may have non-metal layers of material, such as fiber, between the metal layers or on the outside of the metal layers.Type: GrantFiled: January 24, 2000Date of Patent: November 30, 2004Assignee: ATD CorporationInventors: G. William Ragland, J. Bradley Pearce, Christopher V. Ragland

Publication number: 20040231118Abstract: The invention relates to a method for producing a foil material, provided with an embossed hologram. Said method comprises the following steps: optionally metallizing said material, applying a lubricant and then directly embossing said material, the embossed surface remaining the material top layer. Said invention also relates to a foil material having the following structure: a metal layer, provided with an embossed hologram, and a lubricant layer, which is at least partially applied to said metal layer, whereby said material top layer is exclusively formed by the metal layer and/or the lubricant layer.Type: ApplicationFiled: April 5, 2004Publication date: November 25, 2004Inventor: Wolfgang Brickenkamp

Patent number: 6760959Abstract: A die and a method for forming a die to produce optically varying effects in a light reflective surface. A design generally formed as a plurality of parallel grooves of varying widths and depths are engraved in a soft metal foil adhered to a substrate. A hard metal coating is formed on the engraved soft metal foil in a metal plating bath. The hard metal coating, removed from the soft metal foil provides a die formed as a mirror image of the grooves engraved in the soft metal foil. The die is used to deform a reflective surface such that the surface produces optically varying effects. A die formed in the same manner with further processing is used to both deform a reflective surface and hot stamp it to a substrate.Type: GrantFiled: November 13, 2001Date of Patent: July 13, 2004Inventor: Philip Joseph Grear

Patent number: 6722002Abstract: A method for producing titanium alloy brazing strips and the resulting brazing strips and/or foils. The method uses a cold-rolling process without annealing to generate a titanium based multi-layer alloy strip or foil made up of discrete layers of titanium and an additional layer or layers of one or more metals, such as nickel and/or copper, for example, or alloys thereof, with the layer of titanium roll bonded without annealing to the layers of the additional metal(s). The resulting strip or foil can include, for example, Cu/Ti/Cu, Ni/Ti/Ni, and Ni/Ti/Cu, and also, for example, Cu/Ni/Ti/Ni/Cu, and Ni/Cu/Ti/Cu/Ni, among other combinations. The resulting strip or foil can be used for brazing, creating an alloy of the weight percentage of the original materials.Type: GrantFiled: December 16, 2002Date of Patent: April 20, 2004Assignee: Engineered Materials Solutions, Inc.Inventors: Chen-Chung S.

Publication number: 20040064927Abstract: A process for producing a one-piece, structured metal sheet having an interior with a hole, provides a predetermined, curved outer contour and inner contour that delimits the hole. A smooth, shaped blank is produced, having an outer edge substantially concentrically outside the predetermined outer contour and an inner edge substantially concentrically outside the predetermined inner contour. A structure, which preferably has formations running substantially radially, is then stamped into the metal sheet so that the sheet is formed with an approximately uniform degree of deformation in an inner boundary region and an outer boundary region. A metal sheet for a catalyst carrier body has an interior hole, an outer contour, an inner contour delimiting the hole and a structure with formations running approximately in radial direction. The metal sheet is produced in one piece and in particular is seamless.Type: ApplicationFiled: October 6, 2003Publication date: April 8, 2004Inventors: Rolf Bruck, Jorg Zimmermann
