Abstract: An apparatus (10) for shearing off reinforced concrete piles and metal piles, casing and conductor pipes, and crushing reinforced concrete piles has a frame (11) with first and second ends and a cutter blade (41) movably mounted on the frame driven by hydraulic rams (21) between a retracted position adjacent to the first end and an extended position toward the second end. An abutment gate (30) pivotally mounted and latched at the frame second end has vertically spaced first and second abutment surfaces (52A, 52B) and first and second horizontal shearing surfaces (53A, 53B) disposed in parallel vertically spaced relation defining an opening (51) therebetween through which the cutting edge (41B, 41C) of the blade passes. Removable crushing attachments (60A, 60B) allow crushing of concrete piles, and removable arcuate abutment attachments (54) accommodate cylindrical piles, casing and conductor pipes.

Abstract: A portable refrigerant reclamation and purification apparatus removes moisture, oil, solid particulates, non-condensables, acid and other contaminants from refrigerant. Contaminated refrigerant is introduced into a separation chamber and vaporized as it passes over heat exchanger coils. During vaporization the bulk of contaminants are separated from the refrigerant and fall into a sump and the vapors are redirected 180.degree. to an upward flow separating the contaminants from the refrigerant vapors. The vapors are drawn out of the chamber through demisting screens which strip remaining contaminants from the vapors and pass through a suction accumulator to either a compressor. The compressed gases are passed through an oil separator.

Abstract: A portable refrigerant recovery and recycling apparatus and method for removing and recycling chloroflourocarbon (CFC), hydroflourocarbon (HFC) and hydrochloroflourocarbon (HCFC) refrigerants from refrigeration systems through a closed loop connection which prevents the release of refrigerant to the atmosphere. A refrigerant is drawn by suction through a filter in its liquid state and transferred to a storage tank. When all liquid refrigerant has been so transferred, a refrigerant vapor recovery process automatically engages and retrieves and condenses the remaining refrigerant vapors, thus completing evacuation of the closed loop refrigeration system until the refrigeration system is evacuated to a pressure of approximately 29 inches Hg absolute for low pressure refrigeration systemes and 20 inches Hg absolute for high pressure refrigeration systems, at which time the present invention automatically shuts off.

Abstract: A portable refrigerant recovery and reclamation apparatus and method for removing and reclaiming fluorocarbon refrigerants from refrigeration systems through a closed loop preventing exposure of the refrigerant to the atmosphere. A refrigerant is drawn by suction to a boiler chamber, vaporized, condensed, filtered and recycled.
