Abstract: This invention relates to various methods of improving the energy efficiency and utility of roofs typically of the flexible membrane granulated type including shingles and roll roofing using a series of generally continuous curved surfaces although is applicable to all types of roofing including metal, concrete, and clay roofing products. Further, this invention relates to a spacer apparatus used to effect several methods of improving the utility and efficiency of roofing of this class.

Abstract: This invention relates to a building cladding for inclined surfaces such as for a sloped roof. More specifically, this invention relates to a building cladding that is passively responsive to sun elevation angles, is multi-functional, and is substantially uniformly ornamental when viewed from common viewing positions. The cladding is predominantly comprised of pairs of substantially horizontal and vertical surfaces extended horizontally and repeated vertically or along the incline of the building substrate. Substantially horizontal surfaces may be adapted for absorbing solar energy, reflecting solar energy, generating electricity from solar energy, converting solar energy into another form of energy, and or ornamentally matching substantially vertical surfaces.

Abstract: This invention relates to inclined outer building surfaces such as roofs reflectively responsive to sun elevation angle and predominantly ornamental when viewed from common viewing positions. More specifically, this invention relates to methods of sizing, shaping, surface characteristics, and coating resulting in improved performance, increased ornamental quality, improved economy of roofing of this class using human eye contrast sensitivity and visual perception.

Abstract: A braking apparatus for imparting constant mechanical torque to effect a braking action is capable of operating in a constant, smooth, and adjustable manner, yet operates essentially independent of friction and temperature, as well as independent of rotational speed. The braking apparatus includes a hub assembly having a hub, a collar, a plurality of torsional springs, a spring cap, a spring bushing, and damping means, and a sprocket assembly having a sprocket, a hub bearing, a retaining ring, and a plurality of roller assemblies each of which has a roller. The sprocket assembly is rotatably connected to the hub assembly by a hub assembly spring, a sprocket assembly spring, an adjustment cap, and an adjustment means. The apparatus provides braking by releasably contacting at least one of each of the rollers with at least one of each of the torsional springs so as to deflect and then release the torsional spring as the sprocket assembly rotates about the hub assembly.
