| 20100284512 | PROCESS TO DETERMINE LIGHT ELEMENTS CONTENT OF STEEL AND ALLOYS - The present invention refers to the process of determination of light elements, i.e., molar mass lower than 23, within inorganic materials, by means of spectra analysis between 5 keV and 22 keV, obtained from these materials when exposed to X radiation. Particularly, the invention refers to the direct determination of carbon content in steel and alloys. According to the invention process, the inorganic materials are exposed to X radiation and the spectra are organized as a matrix and mathematically processed using chemometric tools properly selected. | 11-11-2010 |

| 20090131243 | METHOD FOR THE REACTIVATION OF THERMALLY AGED NITROGEN OXIDE STORAGE CATALYTIC CONVERTERS - Nitrogen oxide storage catalysts are used for removing the nitrogen oxides present in the lean-burn exhaust gas of lean-burn engines. Here, the purifying action is based on the nitrogen oxides being stored in the form of nitrates by the storage material of the storage catalyst during a lean-burn operating phase of the engine and the previously formed nitrates being decomposed in a subsequent rich-burn operating phase of the engine and the nitrogen oxides which are being liberated again being reacted with the reducing exhaust gas constituents over the storage catalyst to form nitrogen, carbon dioxide and water. Storage catalysts are thermally aged by high temperatures. The aging is due to sintering of the catalytically active noble metal components of the catalyst and to formation of compounds of the storage components with the support materials. According to the invention, the formation of compounds of the storage materials can be largely reversed by treatment of the storage material with a gas mixture comprising nitrogen dioxide and/or carbon dioxide and water vapor at temperatures of from 300 to 500° C. The reactivation can be carried out either directly on the vehicle by setting appropriate exhaust gas conditions or during a routine service by removal of the catalyst from the vehicle and treatment with a gas mixture in an appropriate apparatus. | 05-21-2009 |

| 20100297008 | GANGLIOSIDE ASSOCIATED RECOMBINANT ANTIBODIES AND THE USE THEREOF IN THE DIAGNOSIS AND TREATMENT OF TUMORS - The present invention is related with the obtaining of modified antibodies by means of the DNA recombinant technology from the murine monoclonal antibody P3 (MAb P3) produced by the hybridoma cell line deposited under Budapest Treaty with accession number ECACC 94113026 and from its anti-idiotype murine monoclonal antibody 1E10 (MAbai 1E10) produced by the hybridoma cell line with deposit number ECACC 97112901, with the objective of achieving monoclonal antibodies which preserve the biological function of specific binding to the antigen of the original antibodies, but being at the same time less immunogenic. The chimeric antibodies of the invention contain the variable domains of the murine immunoglobulin and the constant regions of the human immunoglobulin; and those humanized, besides containing the constant regions of the human immunoglobulins, they are modified in the region of the murine frameworks (FRs) and in particular in those zones that could be in an antigenic site for the T cells, so several positions of the FRS are human as well. These antibodies can be used in the diagnosis and therapy of different types of tumors. The present invention is also related with use of the antibodies for therapeutical and diagnostic purposes. | 11-25-2010 |
