Abstract: A shelter structure extending above and below ground level, with a roof supported by posts and with walls, ceiling and basement floor composed of cast rigid plastic foam panels connected to said walls and posts.

Abstract: This includes means and methods of keeping a heavily insulated shelter structure at a substantially even temperature night and day using only fueless solar energy to do so.

Abstract: A portion of the wall or an entire south wall of a shelter structure embodying a metal screen solar heat collector.

Abstract: An exceptionally well insulated solar heat collector arranged to avoid heat leakage therefrom and operate substantially without any pump. This is mainly accomplished by self circulation of the working fluid, using accumulated solar heat.

Abstract: The present invention is directed to a solar heat collecting assembly including a metallic container defining a solar heat collecting space therein. A pair of spaced screen assemblies extend through the heat collecting space and a metallic tube is arranged between the screen assemblies for providing a liquid passageway through said container. A layer of highly reflective material borders the heat collecting space and reflects low micron heat waves toward the screen assemblies and tube to increase the effective heat transfer capability of the container.

Abstract: Damp sand receiving heat through spiraled sheet copper or aluminum tubes conveying heated air or other gas inside a heavily insulated tank is the subject of this present inventive disclosure.

Abstract: Ordinarily and naturally heat, once freed, tends to travel upwardly. Here means and a method causes heat to travel downwardly, to heat any out of sight area where warmth is required.

Abstract: In order to prevent the cooling of the working fluid in a solar heat collecting system, the present apparatus and process responds rapidly to shut off the circulation of the working fluid (either liquid or gaseous) through the solar heat collecting equipment, when the rays of the sun are clouded over or when at nightime, they are non-existent. Solar heat that has been properly accumulated and stored is effectually prevented from radiating back out of the solar heat collecting system into the outer atmosphere.

Abstract: A reduction of first cost and an increase in solar heat collection efficiency are primary considerations. Heat absorbing liquid is confined to a narrow unobstructed path, with wide flairing wings exposed directly to the sun. The need for painted heat absorbing surfaces is largely eliminated. Transparent or translucent cover is easily removable and replaceable.

Abstract: Roofs like other portions of buildings expand and contract with temperature changes in various climates and seasons. Regardless of outside temperature conditions there is almost no contraction and expansion in the roof described. Means and methods are devised for excluding all moisture from roof joints, thus the freezing and thawing conditions which usually exist are here absent. Unlike other roofs there is no overall expansion and contraction to open cracks to receive dampness, or to require roof repair or replacement. This is a permanent non expanding and non contracting roof structure.

Abstract: An inexpensive solar air conditioning system simple to install and operating with a minimum of mechanism. Without any water drip, so customary with the usual air conditioning equipment, it will bring into a shelter structure either cooled air or air warmed by noncostly solar energy.

Abstract: Ordinarily and naturally heat, once freed, tends to travel upwardly. Here means and a method causes heat to travel downwardly, to heat any out of sight area where warmth is required.
