Jayabrata Bhadurt 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).

  • Method and apparatus for achieving higher cooling rates of a gas during bypass cooling in a batch annealing furnace of cold rolling mills
    Patent number: 9303922
    Abstract: A method and apparatus to increase the cooling rate of gas used in a batch annealing furnace of cold rolling mills under bypass cooling. The invention makes use of the higher heat transfer capacities of nanocoolants developed by a high-shear mixing of nanoparticles and stabilizers in a basic aqueous medium for cooling heated hydrogen flowing through a heat exchanger during bypass cooling of the batch annealing furnace. The nanofluid is prepared in a nanofluid preparation unit.
    Type: Grant
    Filed: November 12, 2013
    Date of Patent: April 5, 2016
    Assignee: Tata Steel Limited
    Inventors: Jayabrata Bhadurt, Deb Roy, Subhrakanti Chakraborty, Shantanu Chakraborty, Sumitesh Das, Debashish Bhattacharjee
