Patents by Inventor George Walrath

George Walrath 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: 9428016
    Abstract: A tire inflation system having a spindle, a pump actuating member, and a pump. The pump actuating member may actuate the pump when the pump rotates about an axis, thereby causing the pump to output a pressurized gas.
    Type: Grant
    Filed: October 11, 2013
    Date of Patent: August 30, 2016

  • Patent number: 7507464
    Abstract: A variegated polymeric article such as a variegated siding panel having improved depth of color and a three-dimensional appearance is formed having a substantially clear, methacrylic acid based capstock coextruded to a tinted polyvinyl chloride based substrate material. A specially formulated streaker pellet provides accent color streaks within the capstock to simulate a wood grain appearance. The use of a clear capstock material eliminates the need for capstock tinting necessary in the prior art to color match the capstock to the substrate material in post formed variegated vinyl sidings. Titanium dioxide may also be introduced in small amounts to the capstock to provide further ultraviolet light protection to the underlying tinted polyvinyl chloride based substrate material.

  • Publication number: 20070078191
    Abstract: A composition for forming a reinforced composite siding product and a composite siding product formed by an extrusion process utilizing the composition is provided. The mixed resin formulation utilized to form the composite siding product includes a polymeric resin, a filler, a processing aid, at least one lubricant, and a thermal stabilizer. In a preferred embodiment, the polymer resin is polyvinyl chloride and the filler is talc. The mixed resin formulation may be extruded with a reinforcement material in a screw extrusion process to form a composite siding product. One or more reinforcing fibers may be utilized in the extrusion process. The reinforcement fibers may be present in the final product in an amount up to 25% by weight of the final product. In at least one preferred embodiment, the reinforcement fibers are glass fibers. A weatherable cap may be co-extruded to form the final reinforced, foamed composite siding product.

  • Publication number: 20060103045
    Abstract: A method for incorporating wet use chopped strand glass (WUCS) in a screw extrusion process is provided. A polymeric resin is added to an extruder in a polymer feed zone and conveyed to a first compression zone where the resin is at least partially melted. The molten resin is conveyed to a high volume zone where WUCS fibers are added. In the high volume zone, the flights of the screw may have a greater pitch to facilitate the introduction of the WUCS into the extruder. The molten resin/fiber mixture is conveyed to a second compression zone where the resin and fibers are intimately compounded. Next, the molten resin/fiber mass is conveyed to a low pressure zone where moisture evaporated from the fibers is released through an opening. The resin/fiber mixture is then conveyed through a compression/die feed zone to further compound and mix the resin and fibers.

  • Patent number: 4501883
    Abstract: Self-bondable polyamides are prepared by reacting an aromatic diisocyanate or diamine with a mixture of terephthalic acid and an aliphatic dibasic acid having at least 6 carbon atoms. These self-bondable amides can also be used as topcoats for wires having basecoats of another polymer, e.g. a polyester, polyester-imide, or polyamide-imide.

  • Patent number: 4150190
    Abstract: A method of coating conductors with polyvinyl formal dissolved in a solvent comprising certain monoalkyl ethers of diethylene glycol and triethylene glycol or the monophenyl ether of ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol or propylene glycol. In some cases it is necessary to have a diluent such as an aromatic hydrocarbon present.
