Show moreThis invention relates to the metallurgy of iron and particularly to the separation and recovery of metals from electric arc furnace (EAF) dusts. While the invention discloses a process for the separation and recovery applicable to zinc, lead, cadmium and antimony contained in such EAF dusts, the invention is particularly applicable to the separation and recovery of zinc. This invention describes a method for reducing the zinc contained in an EAF dust, volatilizing the metallic zinc so produced from the mass of the dust, and reoxidizing the metallic zinc to zinc oxide along with the simultaneous regeneration of hydrogen which can be recycled to treat additional EAF dust.

Show moreA method for controlling multiple access of a transmission channel wherein a plurality of different patterns are assigned to a plurality of sending stations so that each sending station corresponds to a unique pattern, preferably a pattern represented by a Binomial coefficient. Each unique pattern is transmitted from a corresponding sending station to the transmission channel by way of a control minislot. Ternary feedback is received from the control minislot. A summation of different patterns within each control minislot are analyzed to detect whether a collision exists between the different patterns within each control minislot.

Show moreA method and apparatus for producing ultrafine metal powders in which a laser beam is focused on the surface of a workpiece or feedstock and moved thereacross so as to create a cavity within the workpiece through melting and vaporization that contains the metal melted to form the cavity. A subsonic pulsating blast of inert gas is directed at the cavity to atomize the molten metal, rapidly cool the resulting droplets, and transport the droplets to a collection area. The cavity formed by the laser beam is a "keyhole" of deep cavity having a depth approximately three to four times greater than its width. The focal point of the laser beam is moved across the workpiece at a rate from approximately 50 to 80 inches per minute to ensure that the molten metal remains in the cavity prior to the gas atomization. Alloy metal powders can be produced by this method of laser blast atomization providing an alloying metal at the base metal where the cavity is formed so that, upon melting of the base metal, the alloy metal will melt into solution with the molten base metal in the cavity prior to gas atomization. Additionally, nonmetallic impurities may be removed from the molten metal contained within the cavity formed by the laser beam by vaporization.

Show moreA coiled metal sheet is placed in a container, which may be thereafter evacuated slowly with the strip outgassing, and then the highly evacuated container is sealed with the coiled strip therein. The evacuated container may be stored until ready to be mated with a high vacuum process chamber. The container is brought to the vacuum processing chamber and is connected thereto; and the coiled strip is unwound from the container and passed through the vacuum chamber, where it is treated while under a high vacuum. The treated strip is then preferably wound in a highly evacuated take-up container. Sponsorship: IIT Research Instutute United States Patent Show less

Show moreA method of providing acceleration support to a combustion engine using an integrated starter/alternator. The integrated starter/alternator is in rotational combination with the crankshaft and connected to a battery system. The integrated starter/alternator is adapted to function at times as a power source adding torque to rotate the crankshaft to overcome friction and non-linear hydrodynamic forces within the engine. At other times the integrated starter/alternator functions as a power generator for subtracting torque from the crankshaft to provide electrical current to the battery system.

Show moreA method for the construction and utilization of a medical records system capable of providing a continuous data stream of epidemiological data to the records system via kits provided to the symptomatic population to obtain and record an epidemiological profile in a searchable database by applying data mining or automated intelligence techniques whereby, when a valid epidemiological profile is established in the database, automated diagnosis and prescription of treatment may be had for patients presenting similar symptoms. Knowledge discovery techniques may further operate on the database to provide suggested courses of treatment for a virtual class of patients, epidemic threat awareness, and knowledge of drug resistance mutations by a pathogen without direct query of the database.
