Abstract: A method and apparatus of treating oil field wastes and particularly spent drilling fluids which contain barite and hydrocarbons which includes placing the drilling fluids into the upper end of a downwardly directed rotating kiln. Fuel and pressurized air are inserted into a furnace connected to the upper end of the kiln for supplying a fire to the drilling fluids in the kiln for igniting and burning the hydrocarbons in the drilling fluids as fuel until the drilling fluid is dry. The high weight impurities are separated from the dried drilling fluid by gravity from the kiln and the light weight fines and more valuable components including the barite are removed from the kiln by suction. The more valuable components are mixed with new components for providing a recycled drilling fluid. The gases separated from the light weight dry drilling fluids are washed to remove any pollutants before exhaustion to the atmosphere. The particulates cleaned from the gases may be recycled to the kiln.

Abstract: A security cabinet designed for use in the home for storage of guns or other valuable articles includes an upright generally rectangular enclosure of plate steel construction having an open front and with a rectangular door frame weldably secured to the walls of the enclosure at the open front side thereof to reinforce and strengthen the enclosure and provide a strong and unyielding supporting frame surrounding the door. A door, also of plate steel construction, is hingedly mounted in the door frame by recessed hinges which are located interiorly of the enclosure and inaccessible to tampering when the door is in the closed position. A locking bracket is welded to the door frame and has a portion which extends through an opening provided in the door and to which a lock is fastened for securing the door in the closed position. A gun rack is provided inside the cabinet, the gun rack being rotatably mounted to provide ready access to all of the guns inside the cabinet.
