  • Patent number: 11098169
    Abstract: A process is provided for making a silica masterbatch, that contains silica and solution-made rubber. The silica masterbatch has physical properties similar to those found in a comparable dry-mixed composition, but the silica masterbatch can be incorporated more easily and less expensively into tires and other rubber products than the dry-mixed composition. A process is also provided for making a masterbatch of silica, a solution-made rubber and an emulsion-made rubber.

  • Publication number: 20190322841
    Abstract: The present invention provides a process for making a silica masterbatch that contains hydrophobated silica, solution-made rubber and emulsion-made rubber. Hydrophobated silica is mixed into a latex emulsion. Solution-rubber crumb in an aqueous suspension is mixed into the latex emulsion, which is coagulated, and a crumb is recovered, further homogenized, dried and baled to yield the silica masterbatch. A well-dispersed mixture of hydrophobated silica and emulsion-made rubber is added into a steam distillation step of a solution-rubber process from which a silica masterbatch is recovered. The emulsion-made rubber can be omitted to make a silica masterbatch of solution rubber and silica without emulsion rubber. The silica masterbatch has physical properties similar to those found in a comparable dry-mixed composition, but the silica masterbatch can be incorporated more easily and less expensively into tires and other rubber products than the dry-mixed composition.

  • Publication number: 20190200033
    Abstract: Embodiments of this disclosure provide an image encoding/decoding methods and apparatuses and an image processing equipment. The image encoding method includes: determining a search sub-region of a current encoding unit from a plurality of sub-regions of a search region according to one or more motion vectors of one or more encoded units; obtaining one or more motion vectors of the current encoding unit based on the search sub-region; calculating residual information on the current encoding unit according to the motion vectors; and encoding the residual information on the current encoding unit into a bit stream. Hence, the search region may be reduced, and the number of search points may be lowered, thereby shortening PMMVD encoding/decoding time.

  • Publication number: 20170267853
    Abstract: A method of using metallized and nonmetallized nanostructured chemicals as surface and volume modification agents within polymers and on the surfaces of nano and macroscopic particulates and fillers. Because of their 0.5 nm-3.0 nm size, nanostructured chemicals can be utilized to greatly increase surface area, improve compatibility, and promote lubricity between surfaces at a length scale not previously attainable.

  • Patent number: 9286660
    Abstract: Embodiments provide a filtering method and device in image processing. The device includes: a dividing unit to divide a first filtering window into blocks; a determining unit to determine a filtering window area according to relevance between a central block and other non-central blocks in the blocks; and a filtering unit to perform filtering processing on an image in the determined filtering window area. With the method and device of the embodiments, a boundary of an object will not be crossed in filtering, and in removing noise, information on other objects will not be introduced to affect the result of filtering. A filtering window size may be determined while filtering is performing, which may be carried out in one path, avoiding time delay resulting from execution of two paths of a conventional method where an edge is detected and then the size of a filtering window is determined.

  • Patent number: 9256929
    Abstract: Embodiments provide a filtering method and apparatus for recovering an anti-aliasing edge. The method includes: calculating, for a nonlinearly filtered image, a variance value of an area surrounding a current pixel used for identifying an edge of the image; and re-filtering the current pixel when the variance value is greater than a predefined first threshold value, so as to recover an anti-aliasing edge. With the embodiments of the present application, aliasing noises resulted from nonlinear transform may be alleviated, thereby recovering an anti-aliasing edge of a natural object.
