Publication number: 20140354138Abstract: The use of the electride form of 12CaO-7Al2O3, or C12A7, as a low work function electron emitter in a hollow cathode discharge apparatus is described. No heater is required to initiate operation of the present cathode, as is necessary for traditional hollow cathode devices. Because C12A7 has a fully oxidized lattice structure, exposure to oxygen does not degrade the electride. The electride was surrounded by a graphite liner since it was found that the C12A7 electride converts to it's eutectic (CA+C3A) form when heated (through natural hollow cathode operation) in a metal tube.Type: ApplicationFiled: April 28, 2014Publication date: December 4, 2014Inventors: Lauren P. Rand, John D. Williams, Rafael A. Martinez

Patent number: 8821716Abstract: The present invention relates to an improved desulfurization process using an ionic liquid compound of general formula C+A?, where C+ represents an organic cation such as alkyl-pyridinium, di-alkyl imidazolium and tri-alkyl imidazolium; and A? is an anion of halides of iron (III), such as, for example, FeCl4?. The desulfurization process is also improved when producing the ionic liquid compound by heating the reactants using microwave energy. The ionic liquids can be used to desulfurize hydrocarbon mixtures by a liquid-liquid extraction.Type: GrantFiled: May 26, 2009Date of Patent: September 2, 2014Assignee: Instituto Mexicano del PetroleoInventors: Natalya Victorovna Likhanova, Rafael Martinez Palou, Jorge Froylan Palomeque Santiago

Publication number: 20140122063Abstract: The invention consists of a method and computing system for recording and analyzing the voice which allows a series of parameters of phonation to be calculated. These transmit relevant information regarding effects caused by organic disorders (which affect the physiology of the larynx) or neurological disorders (which affect the cerebral centers of speech). The classification methods are also considered an essential part of the invention which allow estimations of the existing dysfunction to be obtained and for the allocation of personality. The usefulness of the invention lies in the possibility of applying the dysfunction estimation in primary care service centers for patient screening to specialist care centers, simplifying examination protocols, saving costs and reducing waiting lists. This methodology can also be used for detecting the personality of a speaker by their voice, allowing access to installations or services.Type: ApplicationFiled: May 16, 2012Publication date: May 1, 2014Applicant: UNIVERSIDAD POLITECNICA DE MADRIDInventors: Pedro Gomez Vilda, Victoria Rodellar Biarge, Victor Nieto Lluis, Agustin Alvarez Marquina, Rafael Martinez Olalla

Publication number: 20100314199Abstract: In one embodiment, a fall protection system including a J-shaped stanchion that attaches to a roof truss (or rafter) in such a manner as to enable the entire girth of the roof truss overhang (or rafter) to be the sole support for the stanchion. The stanchion is designed to bend below the fascia and return up above the roof surface where successive stanchions similarly attached are connected via a fall protection guardrails providing fall protection for all workers. This single point of attachment allows the carpenters to attach the stanchions prior to hoisting the trusses onto the roof bearing walls. As soon as the trusses are properly braced, the guardrails can be hoisted and secured. In another embodiment, the disclosure includes a combination fall protection and catwalk system for above-ground floors. In another embodiment, the disclosure includes a fall protection system for reroofing applications.Type: ApplicationFiled: February 16, 2010Publication date: December 16, 2010Inventors: Rafael Martinez, Joseph A.

Publication number: 20100046602Abstract: A symbol timing derivation system derives receiver timing from received symbols which avoids the need for a pilot tone, thereby reducing power consumption and expanding usable bandwidth. The system is implemented by using a calculation that finds the timing phase error. The timing phase error is then averaged and controls a phase locked loop (PLL). This PLL in turn controls a voltage-controlled oscillator, which handles the modem receiver timing. A centroid calculation can be included to bias the voltage-controlled oscillator to push the equalizer coefficients back to the ideal position. The system can be implemented in either a point-to-point modem environment or a multi-point environment, for example, but not limited to, MVL or DMT. The voltage-controlled oscillator may also be implemented to control transmitter timing, so that the central office modem and the remote modem will operate more-or-less synchronously, reducing the need for large equalizer corrections at either end.Type: ApplicationFiled: November 2, 2009Publication date: February 25, 2010Inventors: William Lewis Betts, Rafael Martinez
