20140151041 | FOAMING COMPOSITION WITH WETTABILITY MODIFYING AND CORROSION INHIBITORY PROPERTIES FOR HIGH TEMPERATURE AND ULTRA-HIGH SALINITY - The present invention relates to a method of obtaining and using foaming compositions with wettability-modifying and corrosion inhibitory properties that control the channeling of fluids in naturally fractured carbonate reservoirs, favorably alter the rock wettability in crude oil enhanced recovery processes and control uniform corrosion problems occurring in production rigs under high temperature and ultra-high salinity conditions by the synergistic effect resulting from the supramolecular interaction of alkyl amido propyl hydroxysultaines or alkyl hydroxysultaines with sodium alkyl hydroxysulfonates and sodium alkenyl sulfonates having the formula (1). The foaming compositions with wettability-modifying and corrosion inhibitory properties are tolerant to high concentrations of divalent ions such as calcium, magnesium, strontium and barium and are suitable for use in the reservoir, seawater and/or congenital water characteristic of the reservoir for transporting the crude oil from the reservoir. | 06-05-2014 |
20140319063 | PROCESS TO OBTAIN RANDOM COPOLYMERS DERIVED FROM ITACONIC ACID AND/OR ITS ISOMERS AND SODIUM ALKENYL SULFONATES AND USE OF THE PRODUCT THEREOF - A process for obtaining random copolymers from itaconic acid and/or isomers and sodium alkenyl sulfonates is by polymerization in an aqueous solution via free radicals at an acidic pH in the range from 1.0 to 3.5 and with a redox system as initiator. The copolymers can be used as calcium carbonate and calcium, strontium and barium sulfates mineral scale inhibitors and as dispersants of clays, iron oxides, calcium carbonate and strontium, barium and calcium sulfates. Random copolymers prevent and control damage in an oil reservoir, obstruction of water injection and crude oil production pipelines, and in production rigs due to mineral scale precipitation caused by high levels of salinity of the injection water and formation water. Random copolymers are tolerant to high concentrations of divalent ions, such as calcium, magnesium, strontium and barium, and can be added to the reservoir and to injection or production pipelines, treated water, sea water and water that is used as means of transportation. The copolymers can also be used to inhibit and disperse mineral scale occurring in cooling systems and boilers used in the oil and chemistry industry. | 10-30-2014 |

20080249589 | METHOD AND APPARATUS FOR OBTAINING AND REGISTERING AN ELECTRICAL COCHLEAR RESPONSE ("ECR") - This invention relates to a method and apparatus for obtaining and registering the Electrical Cochlear Response (“ECR”). Particularly, the ECR refers to the electrical activity of the auditory nerve and the intracochlear residual tissue located in the neighborhood of an intracochlear stimulation electrode, when an external sound is presented to a Cochlear Implant user, human or animal. Applicants recognize that an ECR can be thought of as a far-field electrical potential registered on the scalp of an implanted patient. Applicants, through their method and apparatus, can extract that potential from the patient's spontaneous electroencephalographic activity (EEG) and measure it by using an averaging algorithm. The Electrical Cochlear Response can be applied for adaptation, calibration, performance evaluation and failure detection of the Cochlear Implant of the implanted patient. Also Applicants' method can be applied to estimate the audiometric thresholds of the Cochlear Implant even without the implanted patient's knowledge. | 10-09-2008 |
20090259277 | Systems and Methods for Detecting and Using an Electrical Cochlear Response ("ECR") in Analyzing Operation of a Cochlear Stimulation System - Methods and systems for analyzing operation of a cochlear stimulation system. A sound stimulus signal is generated to excite the cochlear stimulation system to operate. During operation, the intracochlear electrodes generate signals into the auditory nerve system. The patient's nervous system's response may be measured as the Electrical Cochlear Response (“ECR”. The ECR can be detected and analyzed for fitting, calibration, performance evaluation and failure detection of the cochlear implant of the patient. Also example methods may be used to estimate the audiometric thresholds of the cochlear implant without the implanted patient's knowledge. | 10-15-2009 |

20120208022 | PROCEDURE FOR OBTAINING GRAPHENE OXIDE NANO-PLATELETS AND DERIVATES AND GRAPHENE OXIDE NON-PLATELETS THUS OBTAINED - A method for manufacturing graphene oxide nanoplatelets and derivative products and the graphene oxide nanoplatelets obtained, comprising two distinct phases, a first phase for obtaining an intermediate material consisting of carbon nanofilaments, each one having a structure comprising continuous ribbon of graphitic material with a small number of stacked monoatomic graphene layers and spirally rolled around and along the main axis of said nanofilaments, and a second phase wherein said carbon nanofilaments are subjected to a high-temperature treatment in order to clean said filaments and increase their degree of crystallinity. Once these nanofilaments are treated, a chemical etching is performed on them comprising an oxidation that causes the fragmentation of the carbon nanofilaments and starts a cleaving method that is completed by physical means in order to obtain graphene oxide nanoplatelets. | 08-16-2012 |

20090016689 | BIRD FLIGHT DIVERSION DEVICE AND SYSTEM FOR FIXING SAME TO OVERHEAD WIRES AND CABLES - The invention relates to a device for diverting the flight of birds in order to prevent collisions with overhead wires and cables, such as high-voltage lines. The inventive device comprises a system for fixing same to overhead wires and cables, from which a central body is suspended. The fixing system enables the device to be mounted to or removed from overhead wires and cables of different diameters manually by one person. The diversion device comprises a modular construction, thereby facilitating the transport thereof and the replacement of any part if necessary. Once assembled, the volume of the device is greater than that of the individual parts. All of the device is made form an electrically-insulating polymer material which does not corrode the cables or wires. Moreover, the device can move and the components thereof can have different colours in order to render same more visible. In addition, the components of the device are perforated such as to have low wind resistance. | 01-15-2009 |
