Abstract: A method and apparatus for cleansing or restoring polluted substances such as soil or sludge has a horizontally mounted main conveyor which moves a polluted substance which is continually dispensed thereon from a main hopper. A pulverizer mounted proximate the main hopper breaks up the polluted substance into relatively small uniform particles before it is dispensed into the auger of moving means. Immediately downstream of the main hopper, in embodiments which require it, is a dry powder hopper for dispensing fly ash, lime, or other absorbent substance, depending on the process being used onto the polluted substance, or after, as it moves from a first to a second location. At the second location the substance is received by an auger apparatus operating in an elongated, angularly disposed, tubular mixing channel.

Abstract: An improved building structure and construction method is disclosed wherein the wall structure includes internal wall forms with cementitious material applied thereon. A reinforcing structure for the cementitious material is provided whereby the foundation wall structure and roof structure are operatively interconnected in a load bearing relationship so that the strength and durability is significantly enhanced. The apparatus for attaching the internal wall forms to the roof structure includes means for conveniently aligning the wall forms in a straight and plumb relationship before the cementitious material is applied.
