David Dobney 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: 12375031
    Abstract: The present specification relates generally to solar (and other) radiation concentration and also to a radiation concentration device and method for manipulating weather and climate conditions for crops. The radiation concentration device includes a receiver supported by one or more support cables such that it receives concentrated radiation reflected from the reflective sheet when the reflective sheet is unfurled, a furling and unfurling mechanism and a compressed fluid source that actuates furling, supply of which is controlled. The method of manipulating weather and climate conditions for crops includes releasing a fluid into one or more inflatables such that one or more drums linked thereto rotate and move transversely away from a central position such that the reflective sheet unfurls and hangs from the drums.

  • Publication number: 20120266866
    Abstract: A cable ganged heliostat used to focus radiation from a moving source onto a receiver is disclosed. The primary application of such an invention relates to reflecting the radiation from the sun onto a stationary target. The device orients a reflective surface to a position necessary for imaging using a mirror adjustment means. The device may be used singly or in a ganged array. The mirror and mirror adjustment means of the device may be supported by cables.

  • Publication number: 20090272374
    Abstract: A radiation reflection device used to focus radiation from a moving source onto a stationary receiver is disclosed. The primary application of such an invention relates to reflecting the radiation from the sun onto a stationary target. The device orients a reflective surface to a position necessary for imaging using a parallelogram type half-angle system. The device may be used singly or in a ganged array.

  • Patent number: 6974605
    Abstract: A system for protecting surfaces and facilitating the removal of unwanted substances therefrom is disclosed, the system including a polymeric coating having a low volatile organics content (VOC) which is safe for the environment, and a cleaner for application to the coating to remove material from the coating, such as graffiti. The coating may be either a water-based epoxy comprising a bisphenol A resin and polyamide resin, or an aliphatic urethane comprising a polymer having reactive sites which react with a isocyanate and an aliphatic isocyanate. The cleaner is suitable for removing all manner of epoxy and urethane based spray paints, indelible inks, industrial chemicals, and the like. The cleaner comprises N-methyl pyrrolidone in a concentration of fifty percent by weight or greater and a surfactant.
