Publication number: 20100200420Abstract: The invention relates to a multi-polar reduction cell for production of a light metal by electrolysis. The cell has an anode, a cathode, and at least one current-conducting multi-polar electrode interposed between the anode and the cathode. The cell has a molten electrolyte containing a metal salt to be electrolyzed held within the cell and preferably has means to maintain an upper surface of the electrolyte at a predetermined level within the cell. The level is preferably maintained above the upper end of the multi-polar electrode(s), at least in use of the cell. The multi-polar electrode has an electrically insulating surface at its upper end that minimizes or eliminates by-pass current between the anode and cathode when the cell is operated. The invention also relates to the method of minimizing or eliminating the by-pass current.Type: ApplicationFiled: September 3, 2008Publication date: August 12, 2010Inventors: Adam J. Gesing, David K.

Patent number: 5931308Abstract: An eddy current separator (10,10a,10b,10c,10d, 10e,10f,10g) and a separation method for separating non-ferromagnetic particles (14) by engaging the particles from above by a distal end (50) of an inclined engagement member (42, 42', 42") to force the particles into a primary magnetic field (34) below a conveyor surface (28) to increase the induced eddy current flow that generates particle magnetic fields such that subsequent release of the particles allows increased magnetic field propulsion to propel the particles distances that vary according to their electrical resistance, densities, shapes and sizes.Type: GrantFiled: July 30, 1997Date of Patent: August 3, 1999Assignee: Huron Valley Steel CorporationInventors: Adam J.

Patent number: 5813543Abstract: A method of sequentially sorting pieces of material in real-time into output bins where each piece has a composition defined by a plurality of control elements. Each piece is analyzed to determine the concentrations of each control element in the piece. The output bins are assigned target concentrations of the control elements that are defined by customer requirements. The method establishes a bin order used during composition checking to place each piece in a selected bin. The selected bin is the highest order bin that can accept a piece while retaining the actual concentration for each control element of the selected bin within the target concentration for each control element of the selected bin. To optimize the value of the input material to be sorted the bin order is established for each piece based on real-time sort parameters that can determine via global optimization of data from similar input material.Type: GrantFiled: August 5, 1996Date of Patent: September 29, 1998Assignee: Alcan International LimitedInventors: Adam J. Gesing, Tom Shaw

Patent number: 5516595Abstract: The invention comprises a method of making self-supporting ceramic and ceramic composite structures by the oxidation reaction of a body of molten parent metal precursor with a vapor-phase oxidant to form an oxidation reaction product. This reaction or growth is continued to form a thick, self-supporting ceramic or ceramic composite body. The body is recovered and in a separate subsequent operation, at least a portion of a surface is coated with one or more materials in order to effect desired changes in the properties of the surface, e.g., hardness, corrosion resistance.Type: GrantFiled: November 16, 1994Date of Patent: May 14, 1996Assignee: Lanxide Technology Company, LPInventors: Marc S.

Patent number: 5409580Abstract: A process and apparatus for melting metals that react rapidly with air at elevated temperatures to form a stable metal oxide and/or that contains a metal oxide prior to being exposed to elevated temperature, while reducing metal losses due to oxidation or the presence of the oxides. The process involves melting the metal in the presence of a molten metal salt metal salt mixture while electrolyzing metal oxide contained in the salt metal salt mixture to convert the oxide to elemental metal. The process requires an metal salt mixture which contains at least 25% by weight, and more preferably 100% by weight, of metal fluoride and which, for the metal being melted, has a composition which remains substantially unchanged during the electrolysis process. The fluoride improves oxide solubility in the metal salt mixture, making it possible to increase current densities without producing anode effects. The stable composition makes it possible to use the metal salt mixture for prolonged periods without change.Type: GrantFiled: July 8, 1993Date of Patent: April 25, 1995Assignee: Alcan International LimitedInventors: Adam J. Gesing, Alan D. McLeod, Ernest W. Dewing
