William C. Norville 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: 8580346
    Abstract: Plastic restoration kits and methods for effectively restoring the light transmission and optical clarity properties to a plastic surface such as an aircraft window. The kits and methods restore plastic surfaces that have been damaged by scratching and/or UV-induced oxidation. The kits and methods employ a polishing composition and optionally a lusterizing composition, each having particles selected so as to polish and lusterize a plastic surface. After polishing and lusterizing, a UV protective composition that forms a hard UV protective coating is applied. The polishing and/or lusterizing compositions may include agglomerated abrasive particles dispersed in a liquid or gel carrier that progressively break down in size when exposed to oxygen and mechanical pressuring during polishing or lusterizing.

  • Patent number: 8574032
    Abstract: Plastic restoration kits and methods for restoring the light transmission and optical clarity properties of plastic surfaces, such as plastic aircraft windows, automobile plastic headlight covers, plastic sunglass lenses, and plastic corrective optical lenses. The kits and methods restore plastic surfaces that have been damaged by hazing, scratching and/or UV-induced oxidation. The kits and methods employ at least one polishing composition configured to improve clarity by removing scratches. A UV protective material is incorporated into at least one of the polishing compositions so that the UV protective material becomes worked into the plastic surface during polishing, and a protective coating that forms a hard protective coating over the plastic surface impregnated with the UV protective material is finally applied. The plastic surface may be heated after polishing and prior to application of the protective coating material.

  • Publication number: 20090148606
    Abstract: Plastic restoration kits and methods effectively the light transmission and optical clarity properties to a plastic light cover on an automobile or other plastic surface such as a sunglass lens or corrective optical lens. The kits and methods restore plastic surfaces that have been damaged by scratching and/or UV-induced oxidation. The kits and methods utilize polishing and lusterizing compositions having particles selected so as to polish and lusterize a plastic surface and a UV protective composition that forms a hard UV protective coating. The polishing and/or lusterizing compositions may include agglomerated abrasive particles dispersed in a liquid or gel carrier that progressively break down in size when exposed to oxygen and mechanical pressuring during polishing or lusterizing.

  • Patent number: 5407615
    Abstract: Polishing compositions and methods are described for removing scratches and other imperfections from a variety of plastic surfaces in order to improve the clarity and optical quality. Such polishing compositions include a blend of suspension agents, at least one suspension agent having thixotropic qualities and at least one suspension agent having constant viscosity; solid abrasive material; water; and a lubricant. The compositions also preferably include a surfactant. The polishing compositions are applied by means of pads made from a variety of materials, including open-cell polyurethane or polyester, fleece wool, cotton, or other synthetic materials. The compositions are applied by hand or by means of a hand-held rotary, orbital, or oscillating machines, with fixed or variable speeds, and are also compatible with existing scratch removal machines, such as robotic machines.

  • Patent number: 5337524
    Abstract: An applicator pad for use with a polishing composition for removing scratches or other imperfections from plastic surfaces is disclosed which is generally tubular in shape, and has a bore therethrough to receive the finger of a user. The circumference of the pad is provided with a plurality of substantially flat working surfaces. The presently preferred embodiment is about two inches long, and has a hexagonal cross-section. Other preferred embodiments have a differing number of sides. The method of the invention is directed to removal of scratches from plastic surfaces through application of a suitable polishing composition to a pad and moving the pad across scratches or other imperfections to be removed. Among materials suitable for repair using the methods and apparatus of the present invention include eyeglasses, watch crystals, gauge faces, and compact discs.

  • Patent number: 5334335
    Abstract: Polishing compositions and methods are provided for removing scratches and other imperfections from a variety of plastic surfaces in order to improve clarity and optical quality. Such polishing compositions include a solid polishing material, water, and an organic solvent containing undecane or any equivalent solvent. They can also include a stabilizing agent such as carnauba wax to keep the other ingredients suspended or otherwise mixed together. The polishing compositions are applied using buffing pads made from a variety of materials, including open-cell polyurethane, fleece wool, cotton, or synthetic materials. The compositions are applied by hand or using a hand-held rotary, orbital, or oscillating buffing machine, and are also compatible with existing scratch removal machines, such as robotic machines used to restore airplane windows.
