    Abstract: Provided are a magnesium-based alloy and a manufacturing method thereof. In the method, a magnesium alloy is melted into liquid phase, and an alkaline earth metal oxide is added into a molten magnesium alloy. The alkaline earth metal oxide is exhausted through surface reduction reaction between the melt and the alkaline earth metal oxide. Alkaline earth metal produced by the exhaustion reacts with Mg and/or other alloying elements in the magnesium alloy so that an intermetallic compound is formed. The magnesium prepared by the method is excellent in fluidity and hot-tearing resistance. To this end, the alkaline earth metal oxide added is CaO, and the added amount of CaO is 1.4 to 1.7 times the target weight of Ca to be contained in the final Mg alloy.

The stiffening member's corrugations are formed by a series of U-shaped portions that alternate with, and are integrally connected to, a series of horizontal upper portions. Each U-shaped portion consists of three planar portions: two substantially vertical side portions and one horizontal floor portion. Each U-shaped portion is reinforced with two parallel raised ribs. In a second embodiment of the stiffening member, the U-shaped portion is reinforced with two parallel tab portions attached at the sides of the stiffening member. The stiffening member nestingly overlies the corrugated deck, and is attached to the deck and to the underlying horizontal beam with either welds or pins.

  • Patent number: 6337143
    Abstract: An insulated appliance which provides a simple, low cost product and method for containing fiber insulation for application to appliances. A combination of an appliance, fiber insulation layer applied to the exterior surface of a wall of the appliance and a multilayer metal foil adhesively bonded to the outside of the fiber layer. This combination is conveniently formed by adhesively bonding the fiber layer to the multilayer metal foil, then applying the fiber layer to the exterior surface of the wall of the appliance. In the appliance final assembly, the fiber layer is contained between the surface of the wall of the appliance and the multilayer metal foil. Optionally, the fiber is contained between two or more layers of multilayer metal foil, whereby one of the multilayer metal foil is in contact with the wall of the appliance.

    Abstract: A flexible corrugated multilayer metal foil structure comprising a stack of metal foil layers which are formed in corrugations extending across a stack of the metal foil layers, wherein all of the layers have the same corrugated pattern and shape as a result of the stack being shaped in corrugations or the layers being separately shaped in corrugations then nested into a stack. A portion of the corrugations of the stack of metal foil layers can be compressed to fold the layers together whereby the layers are interlocked together in overlapping relationship.

  • Patent number: 5853902
    Abstract: A metal support for exhaust gas cleaning has a metal honeycomb core body fabricated by laying a planar sheet on a corrugated sheet and rolling the laminated sheets into a cylindrical configuration. The corrugated sheet has sinusoidal shaped portions having a wave height which is sufficient to contact the adjacent planar sheet and square wave portions which have a wave height which is insufficient to enable contact with the adjacent sheets. The square wave portions have corners which project out beyond the sinusoidal shaped portions and produce agitation and disturb the flow of gas and to induce an increase in the contact efficiency between the gas and surfaces carrying catalytic material. The planar sheet is not limited to continuously flat sheets and can include flat surfaces formed by zigzag or square wave shaped members. These members can be perforate and or made of a mesh material.

    Abstract: The invention relates to a material in the form of a strip having a stiffening corrugation thereon. The corrugation consists of ridges and valleys therebetween which form arcs over the breadth of the corrugation zone. The corrugations form a wave pattern propagating in the longitudinal direction of the strip. The waves have no straight sections, and the relationship between the thickness of the strip T and the corrugation depth A is 0.5T<A<2T. In addition, the height of the arcs is at least as large as the wave length of the waves propagating in the Y-direction and alternating in the Z-direction.
