  • Publication number: 20230340771
    Abstract: A shear wall connector comprising a pre-built member and a connector, the pre-built member comprising a side plate, a peg, and a shear key, the side plate being provided with a first through hole, the peg and the shear key being provided on the inner and outer sides of the side plate respectively, the peg being provided with a threaded hole at the end connected to the side plate and having the threaded hole aligned with the first through hole wherein the connection member comprises an H-beam, the flange plate of the H-beam being provided with a second through-hole and a shear key adaptor hole matching the first through-hole and the shear key in the side plate. The pre-built elements are pre-built in the concrete wall surface and are assembled by means of the connectors. During installation, the shear key is inserted into the shear key adaptor hole.

  • Patent number: 11266704
    Abstract: A total flavonoid extract from Gynura formosana Kitam., comprising 80-85% of rutin. A preparation method comprises selecting a complex enzyme consisting of a specific composition and ratio of enzymes for enzymatic hydrolysis, extracting and concentrating by a macroporous resin, and separating and purifying by a macroporous resin. The extract has therapeutic effect on non-alcoholic fatty liver disease.

  • Patent number: 11214530
    Abstract: A method for the separation of C4 olefin mixtures using anion-pillared hybrid porous materials as physical adsorbents is provided. The anion-pillared hybrid porous material was constructed by metal ions (M), organic ligand (L), and inorganic anion (A), forming a three-dimensional structure (A-L-M). C4 olefin mixtures contact with hybrid porous materials in certain ways, then each single C4 olefin monomer can be obtained. The pore size of anion-pillared hybrid porous materials and the spatial configurations of the anions within the pores can be fine-tuned and pre-designed. C4 olefins with different size and shape can be efficiently separated by the anion-pillared hybrid porous materials through shape recognition and size-sieving mechanism.

  • Patent number: 10681974
    Abstract: An interdental brush has a handle with a helix style shape, as well as sections of long and short bristles to maximize plaque removal. The handle has a first end, a second end and a length between the first and second ends. The handle defines a longitudinal axis extending through the handle along the length. A brush extends from the handle and includes a stem projecting along the longitudinal axis and a set of bristles extending laterally outwardly from the stem. Each of the bristles has a bristle length from the stem to a bristle tip, the bristle tips collectively defining a bristle profile. In one embodiment, the bristle profile alternates along the stem between valley sections of short bristle length and mountain sections of long bristle length. The handle includes a grip portion along the length, and the grip portion is shaped such that it is twisted about the longitudinal axis in the manner of a helix.
