20090061260 | High-Temperature Fuel Cell System and Method for the Production of Contacting Elements for Such a Fuel Cell System - A high-temperature fuel cell system includes individual SOFC fuel cells which are in contact with each other for electrically connecting the same in parallel or in series. In at least one embodiment, contacting elements that are suitable for the fuel cell system with a certain flexibility in addition to the required electrical conductivity for continuous operation. The contacting elements between two fuel cells are formed by a metal wire mesh that is advantageously made of nickel. Such nickel wires can be mechanically transformed into a continuous mesh, especially a tube, from which sections having a suitable length can be cut and be provided with the proper shape. | 03-05-2009 |
20110229796 | PLANAR HIGH-TEMPERATURE FUEL CELL - A planar high temperature fuel cell, a use and a method of manufacture are discloses. The planar high-temperature fuel cell with includes a layer structure. The layer structure includes a cathode layer, an anode layer and a solid electrolyte layer disposed between the cathode layer and the anode layer. Each of the layers are planar. A porous metal structure is used as the support for the layer structure and is also planar. | 09-22-2011 |
20130134101 | Sparging Device for a Flotation Cell - A sparging device for a flotation cell may include a central gas tube with a central gas orifice which is adjoined by at least two connecting tubes each having a connecting gas orifice, the connecting tubes being aligned at a right angle ss to a longitudinal axis LZ of the central gas tube, the central gas orifice being connected to the connecting gas orifices, and each connecting tube being connected to at least one gas injection unit at its end remote from the central gas tube. A flotation cell with such a sparging device and a flotation method are also disclosed. | 05-30-2013 |
20130341251 | FLOTATION DEVICE, METHOD FOR OPERATING THE FLOTATION DEVICE AND USE THEREOF - A flotation device for separating off a valuable mineral from a suspension, has a housing having a flotation chamber, a foam collector for removing a foam product formed in an upper region of the flotation chamber, a feed arrangement for feeding gas and/or suspension into the flotation chamber, an adjustable orifice via which the flotation chamber is horizontally divided into an upper part and a lower part and an open internal diameter of the flotation chamber is locally avoidable. The orifice is arranged completely in a suspension region of the flotation chamber. A measuring arrangement determines a variable in the operation of the flotation device. A control appliance connected to the arrangement automatically adjusts the orifice in dependence on the at least one state variable. | 12-26-2013 |
20140001102 | FLOTATION DEVICE COMPRISING A FLUID DISTRIBUTION ELEMENT FOR GENERATING A FLOW THAT IS DIRECTED AT THE FOAM COLLECTING UNIT | 01-02-2014 |
20140116953 | METHOD FOR OBTAINING METAL-CONTAINING VALUABLE SUBSTANCES FROM A SUSPENSION-LIKE MASS FLOW THAT CONTAINS METAL-CONTAINING VALUABLE SUBSTANCES - A method obtains metal-containing valuable substances from a suspension that contains metal-containing valuable substances. A corresponding suspension which is pressurized after passing through at least one pump device and which is mixed with a gas is fed to at least one jet device of at least one flotation cell via at least one feed line. The metal-containing valuable substances are separated in the at least one flotation cell. The suspension that contains the metal-containing valuable substances is charged with gas at least partially after passing through the pump device before entering the jet device. | 05-01-2014 |
20140130576 | SYSTEM AND METHOD FOR MONITORING CONDITION OF AT LEAST ONE NOZZLE - A two- or three-phase mixture is sprayed using at least one nozzle which has associated therewith at least one structure-borne sound sensor for detecting a sound power level signal in the region of the nozzle and also at least one gas and/or liquid meter for detecting a volumetric flow of gas and/or liquid directed through the nozzle. | 05-15-2014 |
20140209517 | DISPERSION NOZZLE, FLOTATION MACHINE EQUIPPED THEREWITH, AND METHOD FOR OPERATING SAME - A dispersion nozzle for dispersing a liquid with a gas, has a gas feed nozzle and a tubular mixing arrangement which has an inlet zone for the gas and the liquid and an outlet zone for a gas/liquid mixture. The mixing arrangement adjoins the gas feed nozzle. The gas feed nozzle is tapered in the direction of the mixing arrangement and opens into the inlet zone. The mixing arrangement has at least one liquid intake opening in the inlet zone. In the inlet zone a ratio of a diameter DG of a gas outlet opening of the gas feed nozzle and an internal diameter DM of the mixing arrangement is in the range from 1:3 to 1:5. A gas regulating valve meters a quantity of the gas being supplied with the gas feed nozzle. The dispersion nozzle may be used in a flotation machine. | 07-31-2014 |
