Dave Van Vliet 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: 11453779
    Abstract: The invention is directed to a bitumen composition, to a paving, to a roofing, to a method for preparing a bitumen composition, to a method for increasing the stiffness of a bitumen composition, to a method of adjusting the physical properties of a bitumen composition, and to the use of a bitumen composition. The bitumen composition of the invention comprises a lignin compound or derivative thereof, wherein 10 wt. % or more by weight of said lignin compound or derivative thereof is molecularly dissolved in said bitumen composition.
    Type: Grant

  • Patent number: 7160472
    Abstract: Methods and systems for treating a waste stream in a waste treatment system involve performing a unit process of the waste treatment system by contacting the waste stream with oxyhydrogen-rich gas generated on-site by an oxyhydrogen gas generator that implements water dissociation technology. In a preferred embodiment, the oxyhydrogen gas generator involves applying a pulsed electrical signal to a series of closely-spaced electrodes that are submerged in the waste stream to produce oxyhydrogen-rich gas from a water component of the waste stream. Operation of the oxyhydrogen gas generator in the waste stream may accomplish one or more unit processes for waste treatment, such as conditioning, stabilization, thickening, and dewatering, among others. At least a portion of the oxyhydrogen-rich gas can be conveyed for a second use in the waste treatment system, such as a source of combustible fuel for incineration or power generation, for example.
