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.

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.

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.

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.
