Abstract: Panels are formed and mounted in an exterior structure covering assemblage exteriorly simulating a standard exterior structure covering panel assemblage while simultaneously providing a fluid flow network within the panel assemblage for solar heat collection while not substantially disturbing the standard panel assemblage simulation. Generally, the panels have a relatively thin, freely heat transferring exterior layer portion with directly underlying fluid flow channels interconnected between panels for the overall assemblage fluid flow network without substantially disturbing the exterior standard panel simulation. The panels may be formed to simulate any standard roofing or siding panels and the solar heat collecting assemblage may be integrated with adjacent panel assemblages not including the solar heat collecting features with the overall assemblage still maintaining the same standard panel simulation.

Abstract: A dual-actuating flush device for selectively allowing a partial or a full quantity of water to be discharged from the toilet-water tank into the associated toilet bowl; wherein the tank includes independent partial and full flush valve mechanisms to provide conservation of water, each flush valve being arranged at a different water level within the tank, and operably connected to the dual-actuating device which comprises a handle that is operated only in a downward movement for both the partial and the full flush. For a partial flush, which operates the upper level valve, the handle is moved downwardly in a normal manner, with a limited stroke. To provide for a full flush, the handle is pushed inwardly and downwardly, allowing a selective pin to travel in a large elongated groove, thereby extending the downward stroke of the handle, and thus operating the second and lower disposed flush valve, allowing a larger quantity of water to be drained therefrom.
