Patent number: 8975564Abstract: This invention advances the related state-of-the-art by eliminating the physical EO window used by electro-optical imaging infrared seekers for tactical missiles and high-altitude endo-atmospheric interceptors, widely employed in integrated defense systems. This invention increases the probability of intercepting exo-atmospheric ballistic warheads by exo-atmospheric interceptors, and eliminates the existing altitude “gap” of interception, as well as the geographical limitations posed by the mesospheric Noctilucent Clouds. The problem of protecting an imaging EO sensor from aeroheating is solved in this invention by a special purpose device which is enabled immediately after the nose cone ejection event.Type: GrantFiled: April 4, 2011Date of Patent: March 10, 2015Assignee: Sener Grupo De Ingenieria, S.A.Inventors: Jorge Sancho Ponce, Pedro Jose Herraiz Alijas, Rafael Rebolo Gomez, Carlos Miravet Fuster, Aitor Arce Aguinaga, Jose Maria Fernandez Ibarz, Daniel Ribas Nieto

Patent number: 8904789Abstract: The invention relates to a method for generating energy by means of thermal cycles with high pressure and moderate temperature steam, which allows improving the energy and operational efficiency of the conversion of heat energy into mechanical or electrical energy by means of thermal cycles in which the temperature of the steam is limited to moderate values in its generation, comprising the following steps: a) generating steam at a pressure above 65 bar and a moderate temperature below 400° C., b) expanding said steam in a steam turbine, steam of an intermediate pressure, comprised between 10-40 bar, with a moderate moisture, below 15%, being obtained c) drying said steam by means of a moisture separator and reheating said steam, d) expanding said steam in the turbine, and e) heating boiler water used to generate the steam by means of a plurality of steam extractions from the turbine, in order to exchange heat with said boiler water.Type: GrantFiled: February 24, 2009Date of Patent: December 9, 2014Assignee: Sener Grupo de Ingenieria, S.A.Inventors: JoséMaría Menéndez Salcedo, Jerónimo Angulo Aramburu

Patent number: 7431829Abstract: The present invention refers to a method for the regeneration of used petroleum oils which comprises the following steps: (a) demetallization of the used mineral oil by means of chemical treatment of said oil with an aqueous solution of a chemical reagent containing anions which form low solubility salts with the metals of the oil, followed by the separation of the demetallized oil; (b) distillation of the demetallized oil obtained in step (a) at atmospheric pressure and in the presence of alkaline hydroxides; and (c) distillation of the bottom liquid obtained in the atmospheric distillation in step (b) under vacuum and in the presence of alkaline hydroxides to obtain lubricant bases.Type: GrantFiled: September 23, 2004Date of Patent: October 7, 2008Assignee: Sener Grupo De Ingenieria, S.A.Inventor: Jeronimo Angulo Aramburu

Patent number: 7226533Abstract: A process to re-refine used petroleum oils by extraction with aliphatic solvents, wherein after eliminating the extract solvent, the process consists of the following treatments, (a) flash, continuous vaporization, at atmospheric pressure or near atmospheric pressure, to separate the light fractions, in the presence of small amounts of a basic compound or a reducing agent or a combination of both and (b) continuous distillation, in a fractionating column, of the bottom liquid obtained in stage (a), under vacuum and moderate temperatures, in the presence of a basic compound or a reducing compound or a combination of both, with recirculation from the bottom of the column to its feed; separating, as lateral extractions, the vacuum gas-oil or spindle oil and the lubricant bases and, as bottom product, a fuel-oil or asphaltic component.Type: GrantFiled: October 10, 2002Date of Patent: June 5, 2007Assignee: Sener Grupo De Ingenieria, S.A.Inventor: Jerónimo Angulo Aramburu
