  • Publication number: 20200101125
    Abstract: The extract of Vicia faba beans is prepared by soaking beans in distilled water overnight and then boiling in a water bath to reduce the volume of aqueous extract, which is then homogenized and filtered. The filtrate is concentrated to a smaller volume, lyophilized, and powdered. The lyophilized powder is extracted with hexane to remove oils and lipids. The oil-free lyophilized powder is dissolved in ethanol solvent and extracted for eight hours under reflux, and filtered. The volume of ethanol is reduced by a rotary evaporator, and a first off-white precipitate (sample A-1) is collected, washed with ethanol, and dried at 80° C. Mass spectrometry shows a molecular weight of 200.16447 g mol?1, and an empirical formula of C9H16N2O3 is assigned. Intraperitoneal injection of mice with 50 mg/kg of A-1 twenty minutes prior to injection with strychnine protected the mice from strychnine-induced convulsions to the same extent as phenobarbitone (phenobarbital).

  • Patent number: 8972209
    Abstract: A method for detecting an internal failure in a capacitor bank connected in one phase or more phases respectively to a power system. The capacitor bank includes a plurality of capacitor units. Each of the capacitor units includes a plurality of capacitor elements connected in parallel and/or series. The capacitor units are further divided into two strings and a current transformer is arranged in the midpoints of the two strings so that the capacitor units are further divided into four quadrants and the internal failure(s) may occur in one or more capacitor elements or units and involves one or more capacitor quadrants. The method includes initiating an alarm and/or a trip signal when the determined total number of internal elements failures exceeds a first or a second threshold value.

  • Patent number: 8912801
    Abstract: A method for detecting an internal failure in a capacitor bank connected to a power system, wherein the capacitor bank includes a plurality of capacitor units that are divided into two Y sections. Each phase in each of the Y sections defines a leg and each leg includes series and/or parallel-connected capacitor units. The internal failure may occur in one or more capacitor elements or units or involve one or more legs. The method includes measuring the phase current in one of the phases, calculating the root mean square value, denoted by RMS, of the measured phase currents, measuring the unbalanced current between the two sections, calculating the RMS value of the measured unbalanced currents, and detecting the phase angle between the measured phase current and the measured unbalanced current.

  • Patent number: 8823307
    Abstract: A system, method and computer program product for monitoring including detecting internal faults especially inter-turn faults of a synchronous generator and thus protecting the synchronous generator. The synchronous generator includes a winding for each phase of a power network, a terminal for each phase arranged on a terminal side of the synchronous generator, and connected to the respective winding, the terminals on the terminal side are connected to an electrical power network, and the synchronous generator is arranged to input power to the electrical power network by means of the terminals.
