20140114109 | Oxidative dehydrogenation of ethane to ethylene and preparation of multimetallic mixed oxide catalyst for such process - Oxidative dehydrogenation of light paraffins, such as ethane at moderate temperatures (<500° C.) to produce ethylene without the formation of side products such as acetic acid and/or other oxygenated hydrocarbons is achieved using tellurium-free, multimetallic catalysts possessing orthorhombic M1 phase and other crystalline structures that have an important role for obtaining high performance catalysts for the oxidative dehydrogenation of ethane to ethylene. Such catalysts are prepared using thermal and hydrothermal methods. | 04-24-2014 |
20140275685 | MULTIMETALLIC MIXED OXIDES, ITS PREPARATION AND USE FOR THE OXIDATIVE DEHYDROGENATION OF ETHANE FOR PRODUCING ETHYLENE - A layered multimetallic mixed oxide (LMMO) is characterized by one or more diffraction peaks at 5<2θ<15, preferably between 10<2θ<15. The catalysts can be represented by the general formula: | 09-18-2014 |

20130140186 | PROCESS FOR GOLD AND SILVER LEACHING WITH THIOUREA SOLUTIONS - A solution composition that permits the use of thiourea is provided. The process is to form a solution that improves, on one hand, the velocity of gold and silver extraction, from minerals and other materials that contain them, improving the stability of the thiourea in the leaching solution and, on the other, the direct electrorecovery of the metals from the solution. The leaching solution, beforehand or simultaneously, has been subjected to a controlled electro-oxidation to produce formamidine disulfide (FADS) which acts as an oxidizing agent for the mineral phases that contain the gold and silver. In a preferred mode, the FADS is present as 10 to 30% of the total thiourea contained in the solution and the electrodeposition of the metals is performed in the same cell (cathodic compartment) in which the FADS is formed (anodic compartment). | 06-06-2013 |

20110220857 | PROTECTIVE BARRIER FOR WINDS CARRYING SNOW OR SAND - Protective barrier for snowstorms, for installation near communication routes in order to prevent the accumulation of snow or sand on the road. The barrier is formed by joining several screens made of a set of blades that are arranged horizontally, superposed on one another at regular distances, joined with vertical posts by anchoring their ends to several rectangular plates that are inserted in the vertical post using a ring on the plate. | 09-15-2011 |

20140120302 | STRINGER MADE OF COMPOSITE MATERIAL WITH AN ELASTIC RUN-OUT AND METHOD OF MANUFACTURING SAME - A stringer made of composite material for reinforcing aircraft skin panels. Plies are introduced at 90° in a segment close to the stringer run-out, and progressively reducing the number of plies at 0°, such that the majority of the number of plies is at 90° in an segment adjacent to the run-out, so the stiffness of the run-out is reduced, and the load it supports is also therefore reduced. This is an alternative solution to the solutions already existing for getting the stringer run-outs to support a smaller load, thereby reducing both the risk of the plies of the stringer peeling off and the risk of separation between stringer and skin panel. A method of manufacturing said stringer is also provided. | 05-01-2014 |
