Abstract: Process for rolling aluminum foils includes: providing first and second laminates each having two aluminum foils overlapped one to another between which a lubricant is interposed; lubricating one face of one laminate between the first and second laminate; coupling the first laminate with the second laminate obtaining a double laminate. The lubricated face is a contact face between the first and second laminate; or it is a non-contact face between the first and second laminate, in this case being provided the intermediate steps of winding the double laminate obtaining a wound double laminate having n coils; partially separating the wound double laminate by unwinding, by one coil, both the aluminum foils of one of the first and second laminate, obtaining an at least partially wound double laminate having an end portion constituted by a respective portion of both the aluminum foils of only one of the first and second laminate.

Abstract: A method for fabricating a supermirror for forming a neutron guide. In the method, a neutron supermirror, which is widely used in the formation of thin films in cold neutron guides and the spectrometer field, is fabricated with nickel thin films and titanium thin films, having varying thickness, using a combination of monochromator structures in which nickel thin films and titanium thin films, having the same thickness, are stacked in the form of periodic structures. According to the method, a combination of monochromator structures having a variety of different thicknesses is formed, such that the amount of the overlap of peaks due to the monochromator structures can be adjusted to increase reflectivity, and some of the monochromator structures can be removed during the fabrication of the supermirror to make it easy to extract monochromatic beams, such that it is easy to fabricate a transmission monochromator, rather than a reflection monochromator.

Abstract: 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.

Abstract: A joint connecting consecutive sheets of etched regenerator foil for a spiral-wrapped regenerator of a regenerative gas cycle machine such as a Stirling cycle engine or Stirling, pulse tube, or Gifford-McMahon cryocooler. The joint comprises a multiplicity of tabs on the end of one sheet of regenerator foil interlocked with a multiplicity of tabs on the end of another piece of regenerator foil. The joint is no thicker than the original thickness of the sheets of etched regenerator foil that it connects together, and the tabs substantially fill the holes into which they are locked, minimizing undesirable leakage through the joint after it has been incorporated in a regenerator.

Abstract: A method of forming sheets of superplastically formable material into a three dimensional article, the sheets being joined together along diffusion bonds to form discrete cells, at least one gas path being provided through the bond between cells. The sheets are heated to a temperature at which they exhibit superplastic properties and a gas injected between the sheets to expand the cells, the gas paths allowing the injected gas to pass from cell to cell. The edges of the gas paths are locally heated to change the microstructure of the sheets in the edge areas, which reduces the flow resistance of the edges under superplastic forming conditions and thereby reduces the propensity of the diffusion bonds bordering the gas transfer holes to peel apart under the forces of the inert gas exerted on the sheets at the gas transfer paths.

Abstract: A method and system for making a monolithic intermetallic structure are presented. The structure is made from lamina blanks which comprise multiple layers of metals which are patternable, or intermetallic lamina blanks that are patternable. Lamina blanks are patterned, stacked and registered, and processed to form a monolithic intermetallic structure. The advantages of a patterned monolithic intermetallic structure include physical characteristics such as melting temperature, thermal conductivity, and corrosion resistance. Applications are broad, and include among others, use as a microreactor, heat recycling device, and apparatus for producing superheated steam. Monolithic intermetallic structures may contain one or more catalysts within the internal features.

Abstract: The present invention relates to a method of manufacturing a heat shield and to a heat shield manufactured with this method. Heat shields of this type are particularly used in the field of the automobile industry. According to the method according to the invention, an insulating material, performed in a suitable contour and consisting of graphite, for example vermiculite, without binding agent, is inserted as an insulating plate (4) between two flat materials (2, 3), consisting of sheet metal, for example. The flat materials (2, 3) are then connected to one another at their edges in a positive or non-positive manner. The insulating material is here compressed, before or after being deposited on the flat material, to form a coherent insulating plate.
