Patents by Inventor Daniel John Puffer

Daniel John Puffer 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).

  • Publication number: 20190241748
    Abstract: A coating for pelletized thermoplastic road marking material is provided in which at least one of waxes, silica compounds, and inorganic compounds is provided on the surface of the thermoplastic pellet. The pellet is formed by mixing a binder mixture with a filler mixture, heating the mixed ingredients while mixing into a homogenous molten mixture and then extruding the molten mixture. The extruded material is cooled, cut into individual pellets and then coated. The coating prevents clumping of the pellets and also imparts improved flowability and lower melting point properties. Preferred coatings include micronized polyethylene wax, silicates, silanes, silicones, siliconates, fluoropolymers, calcium carbonate and zeolite.

  • Patent number: 10059859
    Abstract: A composition of matter suitable for use as a road marking substance and a method thereof provides for the steps of mixing a binder mixture with a filler mixture, heating the mixed ingredients while mixing into a homogenous molten mixture and then extruding the molten mixture. The extruded material is cooled, cut into individual pellets, coated with an anti-clumping coating and packaged for use in making a road marking substance in situ. The binder can be alkyd-based or hydrocarbon based. The binder includes rosin resins, wax and a plasticizer, and a hydrocarbon resin is added for the hydrocarbon-based binder. The filler contains titanium dioxide, a pigment (if necessary) and ground calcium carbonate.

  • Patent number: 9732480
    Abstract: The invention relates to pelletizing thermoplastic road marking substance containing light-reflective agents, such as glass beads. A dry formulation of the ingredients is transported to a heating station, where the dry mix is heated to a molten state. The melted mix is extruded into form pockets of a moving conveyor. As the conveyor moves through a cooling station, the molten substance in the form pockets solidifies forming individual pellets. The pellets are then removed from the form pockets, packaged and shipped to customers.
