Patents by Inventor Kurt Stephens

Kurt Stephens 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).

  • Core assembly with deformation preventing features
    Patent number: 8276654
    Abstract: A heat exchanger assembly includes a core assembly having air passages that are closed off on at least one side by a closure bar. A reinforcing bar is received within a channel of the closure bar to create an interface with substantially no gaps that may accumulate moisture within the core assembly. The prevention of moisture accumulation at the interface between the reinforcing bar and the closure bar prevents potential damage caused by freezing.
    Type: Grant
    Filed: November 17, 2005
    Date of Patent: October 2, 2012
    Assignee: Hamilton Sundstrand Corporation
    Inventors: Mark Zaffetti, Kurt Stephens, William J. Phillips, Irving O'Strander, Michael Spineti, Virat Saidha
  • Apparatus for reducing thermal fatigue in heat exchanger cores
    Patent number: 7353864
    Abstract: A heat exchanger uses a skeleton forming of a lattice of first and second bars to provide a box-like structure. Blocking bars are arranged between gaps in the first and second bars to provide a blocking surface to divert airflow around a portion of the heat exchanger core. A brazing material is used in the assembly of the core and the skeleton, which includes the blocking bars.

  • Unmanned Urban Aerial Vehicle
    Publication number: 20060284002
    Abstract: The proposed UUAV provides a small, agile vehicle that leverages the unique principals of remote controlled model aviation. The UUAV also encompasses an aerodynamically shaped, gas filled wing that can be used to provide buoyancy for lift assistance both through the use of the lighter than air gas and by its aerodynamic shape in forward flight.
