James R. Bowman 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).

  • Electrospun dextran fibers and devices formed therefrom
    Patent number: 9399082
    Abstract: The invention generally relates to dextran fibers which are preferably electrospun and devices formed from such fibers. In particular, such devices may include substances of interest (such as therapeutic substances) associated with the electrospun fibers. Upon exposure to a liquid the electrospun fibers dissolve immediately and the substances of interest are released into the liquid. Exemplary devices include bandages formed from electrospun dextran fibers and associated agents that promote hemostasis, such as thrombin and fibrinogen.
    Type: Grant

  • Catalytic converter and associated method of assembly
    Patent number: 7774936
    Abstract: A catalytic converter comprises an outer tube, a pair of catalyzed substrates positioned in the outer tube, and a heat shield positioned in the outer tube between the catalyzed substrates. A method of assembling the catalytic converter is also disclosed.

  • Method for assembling a catalyic converter
    Patent number: 7377038
    Abstract: A substrate assembly is stuffed into a converter outer shell to form a catalytic converter having a desired gap bolt density (GBD) value. The substrate assembly is formed by wrapping and taping a mat around a catalytic substrate. A predetermined pressure is applied to the substrate assembly and an outer diameter of the substrate assembly is measured at this predetermined pressure. A GBD value is predicted based on this measurement and if the GBD value is acceptable the substrate assembly is stuffed into the converter outer shell.
