Patents by Inventor Martin R. Burrow

Martin R. Burrow 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: 6569351
    Abstract: The present invention is directed to a an accelerator-gel additive used to deliver an accelerator such as sulfur, into a system for the production of polymer modified asphalt, vulcanized rubber or similar system. Unlike conventional methods of delivering accelerator into the system, the accelerator-gel additive suspends the accelerator in a gel system thereby preventing the sedimentation of the accelerator during processing. As a result, the polymer and asphalt are processed at lower temperature reducing the production of toxic and flammable gases such as hydrogen sulfide.
    Type: Grant
    Filed: March 14, 2000
    Date of Patent: May 27, 2003
    Assignee: Ergon, Inc.

  • Patent number: 6228909
    Abstract: Systems and methods for combining a mineral acid and a polymer additive in an asphalt composition are described. Methods of preparing a polymer modified asphalt include providing a source of a neat asphalt; heating the neat asphalt; providing a source of a polymer; adding the polymer to the neat asphalt to form a blend; providing a source of a dilution asphalt; and adding the blend to the dilution asphalt to form a diluted product. The systems and methods provide advantages in that the addition of the mineral acid widens the temperature range in which satisfactory performance from a given polymer asphalt composition can be achieved or, as a corollary, reduces the amount of polymer additive that would otherwise be needed to achieve satisfactory performance within a given temperature range.
