20070069433 - Versatile high velocity integral vacuum furnace: Versatile vacuum furnace (also having high internal pressure capability) designed for facilitating directed gas flow has a treating chamber including a long, low profile work zone configuration, and powerful gas recirculation equipment with unique structure supporting gas flow patterns that facilitate high velocity gas flow into and through the chamber.... Agent: William R. Jones Solar Atmospheres, Inc.

20070063399 - Metal making lance assembly: An assembly wherein inexpensive and essentially maintenance-free disposable sensors may be used in conjunction with a metal making lance. The assembly contemplates the use of disposable sensors that are accommodated by a sensor feed tube disposed interiorly or exteriorly of a conventional metal making lance. The sensors may be selected... Agent: John F. Letchford Archer & Greiner, P.C.

20070063400 - Metal jet apparatus and jet method: A metal jet apparatus comprises a discharge nozzle 31 for jetting molten metal 20, and a gas passage 33 for supplying inert gas to a peripheral portion of a discharge port 32 of the discharge nozzle 31. The discharge port 32 of the discharge nozzle 31 and an outlet of... Agent: Armstrong, Kratz, Quintos, Hanson & Brooks, LLP

20070057416 - Methods and apparatus for processing molten materials: Various non-limiting embodiments disclosed herein relate to nozzle assemblies for conveying molten material, the nozzle assemblies comprising a body, which may be formed from a material having a melting temperature greater than the melting temperature of the molten material to be conveyed, and having a molten material passageway extending therethrough.... Agent: Allegheny Technologies

20070057417 - Metallurgical lance with annular gas flow control: A method of controlling total jet pressure from the head of a metallurgical lance for introducing gas into a volume of metal in a vessel.
