Patent number: 6788791Abstract: The invention provides method and apparatus that utilize a plurality of port sub-arrays, in which each port sub-array comprises a plurality of acoustical ports. The ports of each port sub-array are spaced so that each port sub-array responds to acoustical signals that are generated by acoustical sources within an associated frequency range. In an embodiment of the invention, associated frequency ranges are related in a harmonic manner, in which each port sub-array corresponds to different frequency octaves. The associated frequency range is a portion of the total frequency range of an acoustical system. Received acoustical signals from each of the port sub-arrays are coupled over acoustical pathways and are converted into electrical signals by capsules that may be mounted in a capsule mounting. The electrical signals may be filtered, such as to reduce spatial aliasing, and post processed to further enhance the characteristics of the signals.Type: GrantFiled: December 20, 2002Date of Patent: September 7, 2004Assignee: Shure IncorporatedInventors: Steven S. Smith, Richard J. Santiago, Mark Gilbert, Alan J. Usdrowski

Patent number: 6709567Abstract: An apparatus for treating a flow of water containing contaminants includes first and second permeable electrodes and a power supply is coupled to each of the first and second permeable electrodes to create an electrical potential therebetween. The first and second permeable electrodes are disposed within the flow of water containing contaminants with the first permeable electrode upstream from the second permeable electrode and the water containing contaminants flowing through and between the permeable electrodes. The permeable electrodes are spaced a select distance to promote an electric current in the water containing contaminants between the electrodes sufficient to sustain oxidation or reduction of the contaminants in the vicinity of the electrodes. The electrodes are preferably substantially planar plates disposed in parallel and substantially normal to the direction of water flow. The distance between the plates is between about 0.001 and 1 meter.Type: GrantFiled: January 29, 2002Date of Patent: March 23, 2004Inventors: Thomas Clay Sale, David Mark Gilbert

Patent number: 6701200Abstract: Automated, custom mold manufacture for a part begins by creating and storing a collection of information of standard tool geometries and surface profiles machinable by each of the standard tool geometries. A customer sends a CAD file for the part to be molded to the system. The system assesses the CAD file to determine various pieces of mold manufacturing information. One or more acceptability criteria are applied to the part, such as whether the part can be manufactured in a two-piece, straight-pull mold, and whether the mold can by CNC machined out of aluminum. If not, the system sends a file to the customer graphically indicating which portions of the part need modification to be manufacturable. With any such modifications, the system provides the customer with a quotation of the cost to manufacture the mold or a number of parts. The quotation is based upon mold manufacturing time as automatically assessed from the part drawings.Type: GrantFiled: January 24, 2002Date of Patent: March 2, 2004Assignee: The Protomold Company, Inc.Inventors: Lawrence Joseph Lukis, Yuri Arnoldovich Dreizin, John Mark Gilbert

Publication number: 20030168246Abstract: A multi-filament superconducting wire in which the filaments comprise zirconia-stabilized ultra-fine grain Nb3Sn. The superconducting wire is formed by wire-drawing a preform comprising a metallic matrix and at least one niobium alloy rod having zirconium and oxygen in solid solution and heat treating the drawn wire in the presence of tin to yield at least one continuous filament comprising ultra-fine grain Nb3Sn having semi-coherent ZrO2 precipitates disposed therein. The ZrO2 precipitates serve to stabilize the ultra-fine grain microstructure of the Nb3Sn at temperatures up to 1100° C. and allows Nb3Sn to maintain the ultra-fine grain microstructure when heat treated at temperatures that are greater than those previously used. By using higher temperatures to form Nb3Sn, the time required for heat treatment can be significantly reduced.Type: ApplicationFiled: January 10, 2003Publication date: September 11, 2003Applicant: GENERAL ELECTRIC COMPANYInventors: Mark Gilbert Benz, Theodore McCall Evenden, Judson Sloan Marte, Thomas Robert Raber

Patent number: 6558446Abstract: An electroslag refining apparatus includes upper and lower integral crucibles, with the lower crucible having a drain. In situ hot start is effected by depositing in the lower crucible a pre-refined starter. The starter is melted in the lower crucible to form a starter pool, and slag is deposited atop the starter pool for being melted thereby to develop a slag pool thereatop. An ingot electrode is lowered through the upper crucible to immerse a tip thereof into the slag pool. The electrode is powered to effect resistance heating of the slag pool to melt the electrode tip. The slag and starter pools are increased in volume into the upper crucible, with the drain then being opened to effect steady state operation.Type: GrantFiled: October 22, 2001Date of Patent: May 6, 2003Assignee: General Electric CompanyInventors: Mark Gilbert Benz, William Thomas Carter, Jr., Robert John Zabala, Bruce Alan Knudsen
