Patents by Inventor Merrill A. Yarbrough

Merrill A. Yarbrough 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: 6465561
    Abstract: The invention includes compositions containing resins (particularly linear crystal polymers) and carbon (particularly impervious graphite) that are made through injection molding and like processes. The compositions produced have enhanced anisotropic thermal conductivity, can have complex shapes as produced by molding that includes lost cores, and are corrosive resistant. The enhanced thermal conductivity can be utilized in applications such as heat exchangers.

  • Patent number: 6253564
    Abstract: A heat transfer system for use in cooling and dehumidifying an interior space while rejecting heat to several alternative sources. The system incorporates three primary heat transfer coils in a mechanical refrigeration cycle to provide comfort cooling to an interior space while rejecting heat to one of the two primary condensing mediums. In addition the beat transfer system of the present invention functions by transferring heat from the atmosphere to a pool, thereby functioning as a pool heater. In a first operating mode heat transferred from an interior space to the ambient atmosphere. In a second operating mode heat is transferred from an interior space to pool water. In a third operating mode heat is transferred from the ambient atmosphere to pool water. A refrigerant-to-water heat exchanger is disclosed having a gas trap for isolating corrosive gases from the metallic heat exchanger components, and further including a sacrificial zinc anode for corrosion protection.
