Abstract: A building includes an inflatable form having an interior surface bounding a chamber. A stabilizing layer of polymeric foam or cementitious material is disposed on the interior surface of the inflatable form. At least one support layer of cementitious material is disposed on the interior surface of the stabilizing layer. Finally, one or more ribs project from the interior surface of the at least one support layer. Each rib includes a core of polymeric foam and a layer of cementitious material disposed over the core.

Abstract: A reclaimer for moving grains and other bulk material in a desired direction includes a substantially cylindrical column upstanding within a storage silo. A track, mounted on the storage silo above the floor, concentrically encircles the column. A motorized carriage is mounted on the track so as to selectively move thereon. Extending between the top end of the column and the carriage is a boom. The proximal end of the boom is rotatably mounted to the column such that movement of the carriage on the tack results in the boom rotating around the column. Suspended from the boom by a pair of winch activated cables is a scraper. The scraper includes an elongated frame having a proximal end that is rotatably and slidably mounted on the column below the boom. Secured along the length of the frame is one or more rotatable augers.
