Abstract: Provided is an apparatus comprising a tensioner, first clamp, first slide, second clamp, and second slide. A tensioner may be adapted to apply a tensile force along a first dimension, may comprise a first end and a second end movable with respect to one another, and may be adapted to apply a clamping force therebetween. A first slide may be adapted to secure the first clamp such that the first clamp is substantially free to move in a second dimension and may comprise a first end and a second end movable with respect to one another. A second clamp may be adapted to apply a clamping force between the first end and the second end and may be adapted to secure the second clamp, such that the second clamp is substantially free to move in the second dimension.

Abstract: Provided is a beam component fixturing apparatus comprising a locator surface set for a first dimension, a locator surface set for a second dimension, and a locator surface set for a third dimension. The locator surface set for a first dimension may comprise a first locator surface for the first dimension and a second locator surface for the first dimension adapted to provide a compressive load on a beam component placed therebetween. The locator surface set for a second dimension may comprise a first locator surface for the second dimension and a second locator surface for the second dimension adapted to provide a compressive load on a beam component placed therebetween. The locator surface set for a third dimension may comprise a first locator surface for the third dimension and a second locator surface for the third dimension adapted to provide a compressive load on a beam component placed therebetween.

Abstract: A clad metal comprising at least one layer of rephosphorized carbon steel metallurgically bonded to at least one layer of stainless steel. In a preferred embodiment the rephosphorized carbon steel layer comprises at least about 0.05 weight percent phosphorus and the stainless steel layer comprises a type 444 stainless steel. A clad metal made in accordance with the present invention may be produced into any one of a variety of shaped, configurations or parts including, for example, slabs, blooms, sheet strip or finished parts. Once the clad metal has been produced by forming a metallurgical bond between the various components thereof, the clad metal may be subjected to further processing including, for example, forging, stamping, rolling, welding, machining, and the like. The invention further provides a unique parting compound for use in the production of clad metals which are clad on only one side. Such parting compound comprises a mixture of levigated alumina and an inert binder.

Abstract: A crucible for containing molten magnesium, and a process for forming the crucible. The crucible is formed from ferritic stainless steel, and particularly type 444 stainless steel plate. The method involves forming ferritic stainless steel plate into component parts of the crucible, while maintaining the ferritic stainless steel plate at temperatures above about 200.degree. F. but below the "blue brittle" temperature range. Further, the method involves special techniques for welding the crucible parts. Specifically, the crucible parts are preheated to a temperature of 100.degree. -150.degree. C. and are completely welded by a process utilizing multiple welding passes with a special metal inert gas shielded welding technique before any cool down of the crucible parts below 100.degree. C. is allowed. The welds extend completely through the crucible walls, which are the thickness of steel plate, and completely incorporate the crucible parts while being essentially free of cracks.
