Publication number: 20190022667Abstract: The present invention provides a multifunctional biological substance separation device or dehydration device illustratively comprising a housing, a spindle push rod running through the housing, a return device, a magnetic sleeve connecting ring, and an electric actuator. An end of the spindle push rod is provided with a magnetic column. The magnetic sleeve connecting ring is provided on the spindle push rod in a sleeving manner and one end, which is positioned outside the housing, of the connecting ring is provided with a magnetic sleeve. The return device is provided in the housing and is used for enabling the spindle push rod to move in a direction away from the magnetic sleeve. The electric actuator is connected to the connecting ring and is used for enabling the connecting ring (and the magnetic sleeve provided thereon) to rotate.Type: ApplicationFiled: August 5, 2016Publication date: January 24, 2019Inventors: Guisheng Yang, Junsen Yang

Patent number: 9355765Abstract: A nano particle/polyamide composite material, a preparation method, and a use thereof are disclosed. The nano particle/polyamide composite material includes 0.01-99 parts by weight of inorganic nano particles and 1-99.99 parts by weight of a polyamide matrix. The preparation method for the nano particle/polyamide composite material includes hydrolysis polymerization or anionic polymerization. The inventive nano particle/polyamide composite material has the particular functions of nano materials, while having the advantages of the polymer matrix including good mechanical performance for easy processing and molding. The nano particle is well dispersed in the polyamide matrix, is physically stable, and has a strong interaction at an interface between the nano particles and the polymer matrix, thus being useful as a structural material, a functional material, and a polymer masterbatch.Type: GrantFiled: December 26, 2011Date of Patent: May 31, 2016Assignee: Shanghai Genius Advanced Material (Group) Co., Ltd.Inventors: Housheng Xia, Guisheng Yang

Patent number: 7772329Abstract: A toughened nylon that comprises a matrix nylon and a long-chain nylon is described. The matrix nylon is prepared by the homopolymerization or copolymerization of cyclic lactams monomers and their corresponding amino acids. The structure of said cyclic lactams is represented by Formula (I) and the structure of amino acids is represented by (I?). In Formula (I) and (I?) A is H or alkyl with 1-8 carbon and 3?n?11. The long-chain nylon is selected from nylons that contain repeating units having structures represented by Formula (II), (III) or (IV). In Formula (II) D is —(CH2)x—, in which H may be substituted with C1-4 alkyl optionally; E is —(CH2)y— or phenylene, in which H may be substituted with C1-4 alkyl optionally; 4?x?34 and 4?y?34. In Formula (IV) 5?u?34, 5?v?34, and u?v. The proportion of said long-chain nylon in the total weight of toughened nylon is 2-45%. As the toughened nylon has very good interface combination, only one melting peak is detected with differential scanning calorimetry.Type: GrantFiled: April 19, 2004Date of Patent: August 10, 2010Assignee: Shanghai Genius Advanced Material (Group) Co., Ltd.Inventors: Guisheng Yang, Tingxiu Xie
