Abstract: A system for adding a predetermined volume of particulate material to a reactor which includes an inclined track mounted on the reactor such that a lower end of the track terminates adjacent an opening in the reactor, and a slideable container mounted on the track for sliding movement from an upper end of the track to the lower end of the track, the container having an internal volume equal to the predetermined volume, and having a forward wall which can be opened to discharge the contents of the container. The container is filled with particulate material, such as sand, when the container is adjacent the upper end of the track. The container is thereafter moved downwardly along the track until the container is adjacent the opening in the reactor, the forward wall of the container is opened to allow particulate material to flow into the opening of the reactor and the container is thereafter tilted towards the reactor to discharge any remaining particulate material in the container into the reactor.

Abstract: A method of constructing a building having load-bearing and insulation properties comprising the steps of erecting a loose frame by first arranging a plurality of horizontally disposed lower steel channels in the form of a closed polygon on a base support, the channels having their ends welded together to form the lower corners of the frame. A plurality of vertical steel supporting posts are mounted on the lower corners and have their lower ends welded to the channels. A plurality of horizontally disposed upper steel beams are arranged in the form of a matching polygon above the channels, the beams having their ends welded together to form the upper corners of the frame. The beams are supported at the upper corners by welding the upper ends of the posts to the beams so as to dispose each upper corner above a lower corner whereby the upper polygon has a matching parallel relation to the lower polygon.
