Patents by Inventor John R. Dees

John R. Dees 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: 4489543
    Abstract: Polyester polymer is extruded through converging capillaries at different speeds to merge and form a combined stream. The stream is cooled to form a filament, which is withdrawn at a high speed. A plurality of such filaments are combined into yarn which self-crimps upon heating. In some embodiments, the yarn has a variable denier.
    Type: Grant
    Filed: December 10, 1981
    Date of Patent: December 25, 1984
    Assignee: Celanese Corporation
    Inventors: James E. Bromley, John R. Dees, Harold M. Familant, Wayne T. Mowe, Darwyn E. Walker
  • Patent number: 4482309
    Abstract: Molten polymer streams are separately metered to the individual capillaries of a combined orifice, rendering the yarn produced less dependent on the capillary dimensions.
    Type: Grant
    Filed: June 6, 1983
    Date of Patent: November 13, 1984
    Assignee: Celanese Corporation
    Inventors: James E. Bromley, John R. Dees
  • Patent number: 4419313
    Abstract: Two molten streams of polyester polymer are extruded at different speeds to intersect below the spinneret. The spinning speed is relatively high, and the resulting filament has shrinkage peaks and valleys along its length. When a number of such filaments are relaxed in a yarn bundle, the yarn spontaneously develops crimp.
    Type: Grant
    Filed: July 9, 1980
    Date of Patent: December 6, 1983
    Assignee: Fiber Industries, Inc.
    Inventors: James E. Bromley, John R. Dees, Harold M. Familant, Wayne T. Mowe, Darwyn E. Walker
  • Patent number: 4414801
    Abstract: A yarn having variable denier filaments with thick and thin regions is drawn at a draw ratio selected to break filaments in the thin regions. This may be done while false-twist texturing. The resulting broken ends protrude from the yarn, giving a spun-like yarn.

  • Patent number: 4411852
    Abstract: Molten polymer streams are separately metered to the individual capillaries of a combined orifice, rendering the yarn produced less dependent on the capillary dimensions.

    Assignee: Fiber Industries, Inc.
    Inventors: James E. Bromley, John R. Dees
  • Patent number: 4376743
    Abstract: A spinneret has a number of combined orifices having different nominal dimensions. Yarns spun from such spinnerets have less doff-to-doff average standard deviation of yarn bulk.

  • Patent number: 4349604
    Abstract: A yarn for producing fabrics with a wool-like hand, by combining textured filaments with longer filaments preferably of larger average denier. The longer filaments thus protrude in loops from the yarn bundle.
    Type: Grant

  • Patent number: 4332758
    Abstract: A yarn for producing fabrics with a wool-like hand, by combining textured filaments with longer filaments preferably of larger average denier. The longer filaments thus protrude in loops from the yarn bundle, and have helical cross-sections.

  • Patent number: 4330591
    Abstract: A yarn for producing fabrics with a wool-like hand, by combining textured filaments with longer filaments preferably of larger average denier. The longer filaments thus protrude in loops from the yarn bundle, and have spiral cross-sections.
