  • Publication number: 20100101565
    Abstract: Passive solar wire screens mount vertically on an edifice. The screens have rods vertically arranged parallel to one another and have wires horizontally arranged parallel to one another. The wires attach to the rods and have first surfaces facing away from the edifice in an upward direction from vertical. The wires also have second surfaces facing toward the edifice in a downward direction from vertical. When the sun has a summer elevation on the horizon, the first surfaces passively reflect solar energy incident thereto away from the wire screens. When the sun has a winter elevation on the horizon, however, the first surfaces passively reflect solar energy incident thereto toward the second surfaces, which in turn passively reflect the solar energy toward the edifice. A concave surface on the wires can also reflect thermal energy back to the edifice.

  • Patent number: 7249789
    Abstract: A novel design for the connection of polyvinyl chloride (PVC) casing. Each length of casing has a male end and a female end. The female end has a narrowing interior diameter with its wider interior diameter at its outermost end sufficient to receive the male end of similar length of casing for connection. The diameter of the female end narrows to a diameter which is less than the outer diameter of the male end. The male end has a lip at its leading edge and is slotted and compressible when forced through the narrowed diameter of the female end. A groove in the interior surface of the female end is sufficient to receive the lip at the leading edge of the male end. When the lip at the leading edge of the male end reaches the groove, it allows the compressed male end to expand with the groove receiving the lip therein. The connected lengths of casing are locked together in this manner.
