Soondeuk Jeung 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: 11925891
    Abstract: A filter media and methods are provided. The media is stretchable and exhibits a high degree of elongation which thereby extends its surface area during pleating. By extending surface area of media during pleating, the initial differential pressure is lowered as the area of media is stretched while keeping the same efficiency range with a compressed thickness of media on the affected area.
    Type: Grant
    Filed: February 10, 2021
    Date of Patent: March 12, 2024
    Assignee: PARKER-HANNIFIN CORPORATION

  • Patent number: 9211688
    Abstract: Methods for preparing composite non-woven fibers-in-fibers, otherwise referred to as composite polymeric fibers having an island-in-sea morphology, are described. The composite polymeric fibers may be prepared by a method that includes melt-blowing a blend of a first polymer and an immiscible second polymer to form the composite polymer fibers. The first polymer forms a matrix that surrounds the second polymer. Typically, the second polymer forms nanofibers within the matrix of the first polymer. The composite polymeric fiber may be treated with a solvent that selectively dissolves the matrix of the composite polymeric fiber and that does not dissolve the nanofibers of the composite polymeric fiber, and the nanofibers then may be collected for further treatment or use.

  • Patent number: 9199185
    Abstract: Disclosed are coalescers, systems, and methods for coalescing a mixture of two phases, namely a continuous phase and a dispersed phase. The disclosed coalescers, systems, and methods include or utilize one or more layers of media material having a distinct mean pore size and wettability. The disclosed coalescers, systems, and methods are effective for removing the dispersed phase from the mixture.

  • Publication number: 20140034564
    Abstract: A filter media is described that employs multicomponent fiber material to form the filter media. The multicomponent fiber material is composed of two or more materials at least one of which is soluable in the application fluid that flows through and is filtered by the filter media to release additive(s) in a controlled manner into the application fluid. The additive(s) releases slowly throughout the filter application life.
