An expanding anchor assembly which after securement can be simply released and immediately easily removed by hand from its embedment matrix substrate without damage to itself, the hole in which it was secured or the matrix substrate in which it was embedded. The anchor assembly 1 comprises one separate tubular sleeve 2, with a bore through its entire length, and another separate elongated cylindrical plug 3. Sleeve 2 has one integral securing component 4 end with parallel longitudinal slots 8 forming a plurality of resilient radially expanable tabs 9 with single internal circumferential protrusions 7 located a predetermined distance from their free end. The other integral joining component 5 end has a means of attaching selected separate objects thereto. Plug 3 is of a length equal to or less than the aforestated protrusion 7's predetermined distance and a diameter movable through bore of sleeve 2. In function, plug 3, in its movement within bore of sleeve 2 toward securing component 4, results in interference with protrusions 7 expanding tabs 9 radially outward to secure anchor assembly in hole 10 of matrix 11 substrate.

A removable anchor assembly has an elongated hollow tube including integral upper and lower portions with at least the lower portion exhibiting resilience to lateral deflection of segments of the walls thereof. The lower portion normally changes in a diameter progressively from near the junction with the upper portion, and the upper portion generally has predetermined internal and external diameters. Longitudinal slots are spaced around the lower portion, and a laterally facing ridge on the lower portion has a normal diameter related to the exterior diameter of the upper portion. A rigid plug is movable through the upper portion and has a diameter functionally the same as that of the internal tube diameter at the upper end of the lower portion. The plug is insertable within the lower portion to wedge the walls thereof outwardly and expand the ridge diameter to an enlarged amount. The plug later may be engaged so as to permit its withdrawal and consequent contraction of the ridge in an amount to enable removal of the anchor from an opening in which it has been secured.

A solar corrugation with shield, which is a stationary device with no moving parts, controls the transmission of solar radiant energy on a supply and demand relationship throughout the seasons of the year. The corrugation has a ninety degree, or thereabouts, angle between its two planar sides, or panes, with one pane being exposed to and the other pane being protected from solar radiant energy. The corrugation is composed of a material transparent to solar radiant energy. The shield is a planar plate, or shield, so positioned to protect the protected pane of the corrugation. The shield, in its position, is separated from the protected pane of the corrugation by an air space. The shield is composed of a material opaque to and absorbent of solar radiant energy.
