  • Patent number: 8962880
    Abstract: An amorphous asiatic tromethamine salt and the preparation method thereof. The method includes the steps of: (1) dissolving asiatic acid in an organic solvent; step (2) mixing with tromethamine; step (3) stirring and salifying the same, and then removing the organic solvent. The method for preparing the amorphous asiatic tromethamine salt is easy and effective, and the water solubility and bioavailability of the asiatic tromethamine salt thus obtained are greatly compared with the prior art.

  • Patent number: 8419961
    Abstract: An oil gas separation membrane combines a gas permeable yet oil and temperature resistant bulk polymer membrane such as poly(tetrafluoroethylene) and poly(tetrafluoroethylene-co-hexafluoropropylene); a porous metal support such as sintered metal frit disk made with stainless steel, bronze or nickel; and an highly gas permeable adhesive that bonds firmly the bulk polymer membrane and the metal frit surface together. The adhesive is either a homogenous polymer that has desirable gas permeability, or a coalescent porous polymer particulates network. A gas sensor employing the oil gas separation membrane for detecting and monitoring fault gases of oil filled electrical equipment requires no mechanical wearing or moving part such as pump and valve and the gas sensor is operated normally under various temperature and pressure conditions.

  • Patent number: 7986533
    Abstract: A shielding assembly comprises at least two shielding modules, each comprising a frame and a cover mounted on the frame. Each of the at least two covers comprises a plurality of engaging portions and a plurality of slots between each two adjacent engaging portions, and one portion of one of the at least two frames abuts one portion of another of the at least two frames. Each of the plurality of engaging portions of one of the at least two covers is received in a corresponding slot of another of the at least two covers to connect the at least two shielding covers to form a cover to reduce electromagnetic interference for an electronic components positioned on a circuit board.
