C22B 9/10

US Classification:

075415000, 148437000, 266233000

Abstract:

A method for producing an aluminum foam product wherein reactive gas producing particles are introduced into an aluminum alloy melt under controlled conditions and subjected to agitation to induce the production of foam-stabilizing by-products, and, under certain conditions, the production of gases used to produce the molten metal foam itself. Foam products produced through this method have intrinsically formed metal oxides and other solid particles dispersed therein and are devoid of the large extrinsically added stabilizing ceramic additions traditionally used in the production of aluminum foams. The invention claims a rapid, single step method for producing an inoculated, foamable melt using low cost precursor materials.

International Classification:

B21D 1102

US Classification:

72298

Abstract:

Apparatus and a method for forming an elongated workpiece are provided. In a first embodiment, a press has a ram and movable upper platen to which is secured a first die. Upper guide members are provided on the upper platen for movement of slide members on each responsive to movement of the platen. Lower guide elements, which cooperate in a telescoping manner with upper guide members, are secured to a lower platen. The first die cooperates with a pair of rotatable second die members which are provided with each being rotatable responsive to movement of a slide member. In a preferred embodiment, the upper guide members secured to the platens are in relative sliding contact and links connect the slide members with the rotatable second dies. In a preferred embodiment, the elongated metal workpiece may be formed by bending under the influence of the forces applied to the first die and second die members through the upper platen by the press ram. In a second embodiment, the press first die and associated guide members are not employed and forming is effected by the second die members.

US Classification:

148633

Abstract:

A method of quenching a metal object having steps of: (a) providing a liquid coolant having a temperature from about 100. degree. F. to about 180. degree. F. and containing about 0. 01 to about 0. 1 standard cubic feet of carbon dioxide gas per gallon of water dissolved therein; and (b) spraying the liquid coolant on the metal object to quench the metal object.

International Classification:

B62D 2300

US Classification:

29620303

Abstract:

An integral structural element particularly well suited as a component of a body-in-white comprises an elongated hollow member with a first end and a second end opposite thereto. A first region, a second region, and a third region extend between a first end and a second end of the hollow member. A first flange extends substantially the length of the elongated hollow member. A second flange extends substantially the length of the elongated hollow member's first region. A first socket or connecting structure is adapted to receive therein a roof header and is disposed on the elongated hollow member between the first region and the second region. A second socket is adapted to receive therein a B-post disposed on the elongated hollow member between the second region and the third region. This integral structural element is a component of a motor vehicle's body-in-white.

US Classification:

148633

Abstract:

A method of quenching a metal object comprising: (a) providing a reservoir of liquid coolant containing gas that has been dissolved therein; and (b) immersing the metal object in the reservoir to quench the metal. The gas is selected from the group consisting of nitrogen and carbon dioxide and is preferably carbon dioxide. The gas is preferably maintained within the range of 0. 001 to 0. 2 standard cubic feet of gas per gallon of coolant. The liquid coolant is preferably water. In a preferred embodiment, the reservoir of liquid coolant is open to ambient pressure and temperature.
