Abstract: A tile lippage removal system preferably includes a spacer post, a threaded cap and an anti-friction protection plate. The spacer post includes a base member, a spacer member and a threaded shaft. A bottom of the spacer member extends from a top of the base member. A break away connection is made between the spacer member and the base member. A bottom of the threaded shaft extends from a top of the spacer member. A plurality of grip extensions extend from an outer surface of a substantial inverted cup to allow rotation of the threaded cap. A female thread is formed in a center of the substantial inverted cup to threadably receive the threaded shaft. The anti-friction protection plate includes a round outer perimeter and a spacer opening, which is sized to receive the spacer member. The anti-friction protection plate may be used to improve existing tile lippage removal systems.

Abstract: A tension solar mirror for a solar collector having a central collector tower is formed from a thin, concave-shaped sheet of fabric, or other flexible material, having a reflective surface on the concave side thereof. The sheet is supported by a plurality of cables attached to a like number of tension towers concentrically positioned the central receiver tower. Due to the action of gravity, the cables assume a natural concave shape that matches the concave shape of the reflective sheet. Further support for the sheet is provided by a small inner ring disposed about the central receiver tower and a larger outer ring near the tension towers. The inner ring is also used as a tie point for cable sections secured to the earth directly adjacent the base of the central tower.
