Abstract: The solar heated building comprises a flexible tube of transparent plastic sheeting adapted to be positioned on, or secured to, a building or anchor unit so as to form the top cover therefor, a pair of shafts engaging spaced internal portions of the tube and extending longitudinally thereof, the tube having closed ends and being positioned to move peripherally, rollers engaging the plastic sheeting and forcing it against the shafts, whereby, on drive of the rollers, the flexible transparent tube can be moved around its periphery, the transparent tube having at least one longitudinally extending section therein with a reflective metal flexible layer thereon, whereby, when the reflective metal layer portion of the tube is so positioned on the roof or cover unit as to receive the sun's rays thereon, they are reflected whereas the flexible plastic tube can be moved around its periphery to have only transparent plastic sheeting receive the sun's rays for transmission of the light's rays therethrough to transmit he

Abstract: A portable structure for use in building pipelines and the like including an inflatable flexible elongated structure having sides and open ends, support track means operably engaged with each side of said structure and extending the structure length, and a plurality of anchor means or assemblies thereof, each including a device to engage the track means, a part of the anchor means engaging the ground to hold the structure against vertical upward movement, but permitting relative movement between the track means and the anchor means so that the structure can be operatively positioned by the anchor means but be movable in relation thereto.

Abstract: The windmill includes a vertically positioned support shaft, a plurality of elongated, molded arcuate plastic vanes which are vertically positioned and operatively connected to the support shaft, which vanes are slightly flexible so winds engaging the vanes will flatten the arc of some vanes and will make the arc of other vanes tighter to provide unbalanced rotational forces on the vanes, and means operatively connect to the shaft to provide power therefrom on shaft rotation.
