| 20110108059 | PLASMA PROCESS AND REACTOR FOR TREATING METALLIC PIECES - The plasma reactor defines a reaction chamber provided with a support for the metallic pieces and an anode-cathode system, and a heating means is mounted externally to said plasma reactor. The plasma process, for a cleaning operation, includes the steps of connecting the support to the grounded anode and the cathode to a negative potential of a power source; feeding an ionizable gaseous charge into the reaction chamber and heating the latter at vaporization temperatures of piece contaminants; applying an electrical discharge to the cathode; and providing the exhaustion of the gaseous charge and contaminants. A subsequent heat treatment includes the steps of: inverting the energization polarity of the anode-cathode system; feeding a new gaseous charge to the reaction chamber and maintaining it heated; applying an electrical discharge to the cathode; and exhausting the gaseous charge from the reaction chamber. | 05-12-2011 |

| 20110212339 | METALLURGICAL COMPOSITION OF PARTICULATE MATERIALS, SELF-LUBRICATING SINTERED PRODUCTS AND PROCESS FOR OBTAINING SELF-LUBRICATING SINTERED PRODUCTS - The metallurgical composition includes a main particulate metallic material, for example iron or nickel, and at least one alloy element for hardening the main metallic material, which form a structural matrix; a particulate solid lubricant, such as graphite, hexagonal boron nitride or mixture thereof; and a particulate alloy element which is capable of forming, during the sintering of the composition conformed by compaction or by injection molding, a liquid phase, agglomerating the solid lubricant in discrete particles. The composition may include an alloy component to stabilize the alpha-iron matrix phase, during the sintering, in order to prevent the graphite solid lubricant from being solubilized in the iron. The invention further refers to a self-lubricating sintered product, obtained from the composition, and to the process for obtaining said product. | 09-01-2011 |
| 20110286873 | COMPOSITION OF PARTICULATE MATERIALS FOR FORMING SELF-LUBRICATING PRODUCTS IN SINTERED STEEL, PRODUCT IN SELF-LUBRICATING SINTERED STEEL AND PROCESS FOR OBTAINING SELF-LUBRICATING PRODUCTS IN SINTERED STEEL - The composition includes the iron as the main particulate metallic material; at least one particulate alloy element, with the function of hardening the ferrous structural matrix; and a precursor non-metallic particulate compound, generally a carbide or a carbonate, which is capable of generating, upon its dissociation during the sintering, graphite nodules, whose formation is facilitated: by the precursor compound itself when it includes a chemical element which stabilizes the iron alpha phase of the ferrous structural matrix; or by an additional alloy element included in the composition and which is defined by a chemical element that stabilizes the iron alpha phase during the sintering. The composition can be conformed by compaction or by powder injection molding. The process of the invention leads to obtaining products in self-lubricating sintered steel from said composition. | 11-24-2011 |

| 20120042240 | SYSTEM AND METHOD FOR AUTOMATIC PAGE LAYOUT - The present disclosure includes a system and method for automatic page layout. One automatic page layout method includes dividing a plurality of ordered graphical items into groups, and bisecting a space into regions having a reading order corresponding to an order of the ordered graphical items, each region corresponding to one of the groups and being sized according to a first layout characteristic of the ordered graphical items of the region's corresponding group in proportion to a second layout characteristic of the plurality of ordered graphical items. An output is caused in which each region has been filled with that region's associated group of ordered graphical items. | 02-16-2012 |
