IPC: C22C45/00
Filed: 1985-08-30
Abstract: An extended surface area amorphous metallic article and process for preparation thereof, wherein a homogeneous amorphous metallic alloy is phase-separated to produce two interconnected, internally continuous, amorphous phases, and then one phase is removed. Preferably, the homogeneous metallic alloy has a composition associated with a eutectic between at least two solid solutions. Phase separation is accomplished by exposing the alloy to a temperature which is below the crystallization temperature and also below the phase separation temperature for that composition. Removal of one phase may be accomplished by leaching in a liquid solution, or by vaporization. The resulting article has an extended surface area of the amorphous phase that is not removed. A porous membrane having extended internal surface area may be prepared by continuing the removal process to the removal of one phase throughout the entire thickness of the article. The extended surface area articles, wherein the extended surface area is of an amorphous metal, enjoy particular advantages when used as catalysts.

Title: Furnace tap hole closure means
Inventor: EASTWOOD OWEN
IPC: F27D3/15
Filed: 1987-01-28
Abstract: It is known to deposit refractory members in the furnace to close the tap-hole using a boom, enabling accurate deposit of the members on the surface of the melt. If, however, a furnace is rotated whilst a boom is in the furnace, the boom will be carried round causing considerable damage to staging supporting the boom. To overcome this problem, the rib boom is a two-part construction with a leading section 11 secured to a trailing section 14 in such a manner that the leading section becomes detached from the trailing section if it is subject to excess load. e.g. by contact with the furnace door during rotation. The bolts 15 connecting the sections engage in open slots in lugs 10 on section 11. <IMAGE>
