20080047396 - Method for controlling a molten metal bath bubbling in a metallurgical vessel and a device for carrying out said method: The inventive method consists in introducing a stirring gas through the vessel (1) bottom, in receiving a measurable mechanical vibration by at least one sensor fixed to the vessel or to the supporting frame thereof, in filtering the thus detected vibration signals by a high pass filter (13a) and preferably... Agent: Oblon, Spivak, Mcclelland Maier & Neustadt, P.C.

20080047397 - Process and apparatus for producing metals and/or primaryh metal products: The invention relates to a process and an associated apparatus for producing metals and/or primary metal products, in particular pig iron and/or primary pig iron products, in which a metal-containing charge material, in particular in fine particle form, is introduced, using pneumatic conveying, by means of a carrier gas stream,... Agent: Ostrolenk Faber Gerb & Soffen

20080034921 - Production of metal nanoparticles: Processes for the production of metal nanoparticles. In one aspect, the invention is to a process comprising the steps of mixing a heated first solution comprising a base and/or a reducing agent (e.g., a non-polyol reducing agent), a polyol, and a polymer of vinyl pyrrolidone with a second solution comprising... Agent: Patent Administrator Cabot Corporation

20080034922 - Method of degassing molten metal: To degas a molten metal, a receptacle containing the molten metal and a layer of slag over the molten metal is positioned in a chamber, and the chamber is evacuated. As the pressure in the chamber reduces, gas is generated at the interface between the molten metal and the slag,... Agent: Edwards Vacuum, Inc.

20080034923 - Recycling method for al-bac composite materials: A method is described for reclaiming an Al—B4C composite scrap material. The method involves heating a liquid pool of molten aluminum while also pre-heating the scrap material. The scrap material is then added to the molten aluminum and a predetermined melt temperature is maintained in the liquid pool until all... Agent: Banner & Witcoff, Ltd.

20080028889 - Process for making highly dispersible spherical silver powder particles and silver particles formed therefrom: Disclosed is an improved process for making highly dispersible, spherical silver particles. In particular, the invention is directed to a process for making silver particles, which are very high solids and highly ordered. The silver particles formed are particularly useful in electronic applications.... Agent: E I Du Pont De Nemours And Company Legal Patent Records Center

20080028890 - Dust suppression and reduction of surface oxidation for mineral agglomerates: The present invention provides a composition consisting essentially of a mineral substrate and a dust suppresant, which is adhered to the surface of the mineral substrate, and methods of reducing dust generation of a mineral substrate by applying a dust suppresant to the surface of the mineral substrate. The dust... Agent: Ciba Specialty Chemicals Corporation Patent Department
