    摘要： Foamed metal surfaces can be contoured as desired by crushing the foam to the desired shape. For example, foamed aluminum to be shaped is placed in a jig and a shaping platen is gradually lowered into the surface of the foam. This process compresses the top cells of the foam to the depth of contouring. The crushed area remarkably conforms to the shape of the platen with little or no rounding, bending, or other untoward deformation in the original surface adjacent to where the crushing force was applied. Brittle, fragile, or frangible foams are not desired starting materials for the process. Efficacious aluminum foams are prepared from base metals having less than about 2 per cent silicon and optionally up to about 15 weight per cent of a metal selected from magnesium, copper, and zinc. The crushing force used for contouring can also be utilized to clad a lamination of metal foil or plastic film to the foam surface being treated.

    摘要： The present invention is a light weight, internally stiffened shell structure constructed in the particular shape and with the contours required of structural members in a variety of applications, and a novel method for fabricating the same. The invented structure provides a heretofore unattainable strength to weight ratio and is therefore particularly advantageous in applications such as the rotating blades and stationary vanes in airborne or ground powder conversion equipment. The invented structure is a suitably shaped and contoured honeycomb panel comprising a metallic flanged honeycomb core material interposed between, and joined to, a pair of relatively thin corresponding metallic sheets which form the skin of the shell structure. Typical metals used to construct the structure are the wrought alloys such as titanium, aluminium and stainless steel, nickel base alloys, cobalt base alloys and columbium base alloys, etc. The invention also contemplates the inclusion of tubes through the core materials to increase shear and bending stiffness and the provision of fluid flow passages through the core material when required by the application. The invented method for fabricating the structure broadly involves the steps of fabricating a honeycomb panel blank, crushing, die forming, creep twisting and diffusion bonding.

    摘要： METAL BELLOWS ARE FABRICATED BY DIFFUSION BONDING THIN GAUGE SHEET METAL ANNULAR RING LEAVES. THE MULTIPLE ANNULAR SHEET METAL RING LEAVES ARE STACKED COAXIALLY AND SIMULTANEOUSLY ALTERNATIVELY JOINED IN PAIRS BY DIFFUSION BONDING ON THE INSIDE AND THE OUTSIDE RING DIAMETER LAND AREAS. THE STACKED COAXIAL ASSEMBLAGE OF THIN SHEET METAL ANNULAR RING LEAVES ARE BONDED INTO ACCORDION-FOLD, MULTIPLE PLEATED BELLOWS. THE FABRICATION PROCESS EMBODIES THE USE OF PRESSURIZING FIXTURE TOOLING COMPRISING AN EXTERNAL STEEL CYLINDRICAL RETAINER RING AND AN INTERNAL STEEL CYLINDRICAL RETAINER PLUG, TOGETHER WITH A FORCE TRANSMITTING ANNULAR RAM AND MULTIPLE THIN STEEL PRESSURE SUPPORT RINGS USED TO TRANSMIT THE BONDING FORCES OF A HIGH PRESSURE RAM. THE DIFFUSION BONDING PROCESS REQUIRES ELEVATED TEMPERATURES OF 1600-1700*F. AT 500 P.S.I. PRESSURE FOR 5 HOURS FOR TYPICAL THIN SHEET METAL TITANIUM ANNULAR RING LEAVES. BY PROPERLY SHAPING THE INNER EDGE AND THE EXTERNAL EDGE OF THE ANNULAR RAM TRANSMITTING THE BONDING FORCES, THE CLEAN, ALTERNATIVE OUTSIDE AND INSIDE ANNULAR LAND AREAS OF ADJACENT PAIRS OF THE SHEET METAL RING LEAVES ARE BONDED INTO HOMOGENEOUS EDGES OF AN ACCORDION-FOLD PLEATED BELLOWS. THE FIXTURE TOOLING, INCLUDING THE STEEL FORCE TRANSMITTING RINGS ARE LATER REMOVED, ALUMINUM, STAINLESS STEEL, TITANIUM, NICKEL, TANTALUM, MOLYBDENUM, ZIRCONIUM AND COLUMBIUM THIN METAL SHEET STOCK MAY LIKEWISE BE FORMED INTO BELLOWS BY THIS IMPROVEMENT IN THE FABRICATING PROCESS.

    摘要： A component to have a passageway or passageways therein, for example for the flow of cooling fluid, is formed in two or more parts which fit closely together so that one surface of one part is adjacent a surface of the other part. At least one of the mating surfaces has grooves or channels therein which are to form the passageways for the cooling fluid. Thereafter the channels or grooves are evacuated and a vacuum seal provided. According to one process or method the parts have extending lips which are welded or otherwise joined together to form a seal for the evacuated channels. According to another method or process, the two parts after being fitted together are enclosed in a thin walled metal jacket of resilient material and the jacket evacuated and sealed. The sealed parts are then subjected for a suitable time and at a suitable temperature, as by placing in an autoclave, to a pressure in excess of that required to force the mating surfaces into intimate contact and sufficient to produce some deformation, with a resulting good bond but without so greatly reducing the cross-sectional area of the grooves or channels as to make them unsuitable for use as fluid flow passageways. One process aforedescribed is also a process for healing internal flaws. After the bonding is complete, the assembly is cooled and removed from the jacket, or the lips machined off, according to the process employed. An additional step may include annealing to produce further grain growth across the boundary between the parts joined together. In a further process, the passageway is filled with an inert gas at low pressure during the autoclave run. In an additional process, the passageway contains a solid or fluid ''''getter'''' material. In a still further process the passageway or passageways are continually pumped out while the assembled parts are being heated and subjected to external pressure.

    摘要： 933,533. Opening containers. KELSEYHAYES CO. June 14, 1961 [June 20, 1960], No. 21519/61. Class 66. An opening device for a sealed container having at least one wall of cold pressure weldable material comprises a tear tag A, Fig. 2F, which is cold pressure welded by a linear indentation joint to the container wall B from the outside, the weld extending to a depth below the interface of the tag and container wall, and the tag being of softer material and thicker than that of the container wall. The tag, which is preferably twice as thick and half as hard as the container wall, may be used to tear a pouring hole, Fig. 1, the weld being formed along a circular strip 12; or it may provide both pouring and vent holes, Figs. 3 and 4 (not shown); or it may be combined with score lines formed in the container, Figs. 5 and 6 (not shown). Specifications 711,889 and 881,255 are referred to.
