  • Patent number: 9091742
    Abstract: The present techniques include methods and systems for detecting a high resistive ground fault condition in an HRG system. Embodiments include systems and methods of measuring drive voltages and detecting voltage changes in the drive once the drive is in operation, particularly for drives operating at relatively low voltages and frequencies. In some embodiments, an integrator is utilized to detect peaks in the measured voltage changes. Relatively small ground currents are also measured to determine HRG faults. Moreover, in some embodiments, the detection of an HRG fault for one of several motor drives provide indication for the particular motor drive in fault.

  • Patent number: 9072762
    Abstract: The combination of gallic acid, ellagic acid, and rubusoside was shown to inhibit angiogenesis by inhibition of pro-angiogenic factors. These three compounds were shown to be absorbed from the intestine making the compounds orally bioavailable. The ratio of the three compounds in the composition was a weight ratio of approximately 1:1.7:17.0 of gallic acid, ellagic acid, and rubusoside, respectively, resulting in a composition with 5% w/w gallic acid, 9% w/w ellagic acid, and 86% w/w rubusoside. This combination was also shown to reduce weight gain, fat accumulation, and serum cholesterol in mammals fed a high fat diet. It also reduced serum triglycerides and tended to reduce blood glucose in mammals on both normal and high fat diets. This three-compound composition (“GER”) can be used to treat diseases associated with angiogenesis and to decrease effects of a high fat diet.

The conical solid-liquid separator and its operating process are simplified to reduce water consumption and improve the processing efficiency. In addition, the conical solid-liquid separator comes with a simple and compact structure and reduces the power consumption significantly.

  • Publication number: 20150110862
    Abstract: Sweet gum (Liquidambar styraciflua L., family Hamamelidaceae) fruit extract was discovered to possess potent activities against multiple targets of the PI3K (phosphatidylinositide 3-kinase) pathway, especially the PI3K/Akt and mTOR pathways. At a very low concentration of 1.85 ?g/ml (IC50), sweet gun extract showed the ability of simultaneously blocking the pathways of PI3K/Akt (upstream), mTOR (mammalian target of rapamycin) (downstream), as well as its downstream protein products S6K and S6. It was also able to block 5-HETE, a lipoxygenase product that contributes to inflammation and activation of PI3K/Akt. The sweet gum fruit extract was prepared with 50% methanol (47:1; raw to extract) and concentrated to an organic fraction (210:1 raw to extract) referred as LIS-100 via reverse-phase column chromatography using a bioassay directed fractionation approach.

  • Publication number: 20150027379
    Abstract: An automatic feeding apparatus includes a reaction container, and two or more dosing containers installed above the reaction container and having a feeding end extending into the reaction container. The reaction container has a water inlet formed on a sidewall of the reaction container and a siphon draining device installed at the bottom of the reaction container for discharging a liquid from the reaction container to the outside. The reaction container includes a mixer that divides the reaction container into an upper-layer reaction area and a lower-layer reaction area. Therefore, a liquid and/or a powder in the dosing container flows into the mixer, and then flows into water through the lower-layer reaction area and the water inlet for dilution. If the water level of the lower-layer reaction area exceeds the siphon level, the mixed liquid will be discharged out of the reaction container by the siphon effect.
