Patents by Inventor Yingchun Ru

Yingchun Ru has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9391515
    Abstract: An apparatus may be provided. The apparatus may comprise a first circuit portion, a second circuit portion, and a third circuit portion. The first circuit portion may comprise a voltage supply having an input voltage level (Vin) and a first switch. The second circuit portion may comprise a plurality of parallel paths. The third circuit portion may comprise a second switch and a third switch. The plurality of parallel paths may supply a portion of the input voltage level when the first switch is open, the second switch is closed, and the third switch is open.
    Type: Grant
    Filed: November 18, 2013
    Date of Patent: July 12, 2016

  • Patent number: 8940939
    Abstract: A process of oxidizing cyclohexane, comprising feeding cyclohexane, an aqueous hydrogen peroxide solution and optionally an organic solvent into a reaction zone through a feed inlet thereof under the oxidation reaction conditions for contact, and providing all or most of the oxidation product at the reaction zone bottom, wherein a part or all of the packing in the reaction zone is a titanium silicate molecular sieve-containing catalyst. The process of oxidizing cyclohexane according to the present invention carries out the oxidation in the reaction zone, which, firstly, utilizes the latent heat from reaction sufficiently so as to achieve energy-saving; secondly, increases the yield of target product and the availability of oxidizer; and thirdly, allows the separation of the oxidation product from the raw material cyclohexane as the reaction proceeds, such that the cost for subsequent separations can be saved.

  • Patent number: 8349756
    Abstract: A noble metal-containing titanosilicate material, characterized in that said material is represented with the oxide form of xTiO2.100SiO2.yEOm.zE, wherein x ranges from 0.001 to 50.0; (y+z) ranges from 0.0001 to 20.0 and y/z<5; E represents one or more noble metals selected from the group consisting of Ru, Rh, Pd, Re, Os, Ir, Pt, Ag and Au; m is a number satisfying the oxidation state of E. The crystal grains of said material contain a hollow structure, or a sagging structure. In said material, the synergistic effect between the noble metal and the titanosilicate are enhanced. As compared with the prior art, the selectivity, catalytic activity and stability of the reaction product are obviously increased in the oxidation reaction, e.g. the reaction for preparing propylene oxide by epoxidation of propylene.
