Abstract: A quick disconnect coupling for high pressure hoses or pipes of various diameters features safety, ease and convenience of assembly and disassembly and simplicity of construction. The coupling is a separate assembly from the hose or pipe with which it is connected rather than being contiguous therewith. Only three coupling components and a ring type resilient seal are involved in the coupling. The two interfitting coupling elements have wrench flats thereon and a threaded collar positively holds the coupling elements in assembled relationship.

Abstract: Large amounts of industrial wastes are drawn by high vacuum into a scrubber and separator unit at the entrance of which the bulk wastes are flooded with water and reduced to slurry form. In the separator, the slurry is centrifugally spun and separated from the entraining air and delivered by gravity into a slurry tank from which the slurry is pumped to a remote disposal site. The air passes from the separator to a surge chamber where the air is spun and expanded and ridded of entrained moisture. The dry air in a clean state after passing serially through the vacuum producer and a silencer is expelled to the atmosphere. The equipment can be mounted on a vehicular base. The apparatus can operate to continuously and simultaneously remove and dispose of industrial wastes.
