Abstract: An apparatus and method for providing an atomizing, shaping and driving fluid that can be used primarily in the painting industry. The apparatus includes a first heating and cooling unit for heating or cooling the paint carrying fluid, a series of nitrogen, carbon dioxide, and argon units for adjusting the concentration of nitrogen, carbon dioxide, and argon in said fluid, a manifold for mixing and controlling the flow rate of said fluid, a second heating and cooling unit for heating or cooling the fluid exiting said manifold, and an ionization unit for adjusting ionization of the fluid exiting the second heating and cooling unit.

Abstract: Disclosed is a process for disinfecting the sludge bi-product of an organic waste stream of pathogenic bacteria and helminth ova commonly found in organic sludges, which includes the step of intimately contacting sludge with an effective amount of an aqueous solution having a solute of at least one of a class of chemical compounds which liberate methyl-isothiocyanate gas upon commingling with organic sludge. Following disinfection the sludge may be subjected to supplemental process for extermination of enteric virus and/or conditioned for recycling as a nutricious plant medium.

Abstract: The apparatus for video inspection of the interior surface of tubular goods, includes: an elongated mounting plate having a first and a second end; a first compartment at the first end of the mounting plate which has a light transmissive window facing the second end of the mounting plate; a second compartment at the second end of the mounting plate which has a light diffusing window facing the first end of the mounting plate; a video camera having a wide angle lens in the first compartment; a light source in said second compartment; a first prism disposed in front of said lens; and, external means for monitoring and recording camera output.The wide angle lens in combination with the first prism provides for a dual field of view, part of which is transmitted through the first prism for viewing a small circumferential area opposite the inclined side of the first prism, and, part of which constitutes a peripheral view of nearly the entire circumference, "C", of the tubular received directly by the lens.
