Abstract: A method for preventing fires and explosions and thus controlling excess temperature within a burn-off or reclamation furnace including a water injection nozzle within the furnace, an automatic valve assembly connected to a source of water under pressure to turn the water on and off, an input burner to heat contaminate materials, an afterburner to burn volatile gases given off by the contaminate materials as they are heated, a temperature sensor located in the discharge from the afterburner to actuate the automatic valve assembly open and closed responsive to the temperature of the discharge, the temperature of the discharge depending on the rate of emission of volatile gases from the contaminate material so that if a high emission rate causes a predetermined temperature to be exceeded the valve assembly opens and the water injection nozzle sprays water on the contaminate materials to cool them and decrease the emission rate until the valve assembly closes.

Abstract: A scissor hoist attachment for pickup truck beds to convert a fixed bed truck with a passenger cab and hauling bed supported on a frame to a tilting bed truck. The hoist upon installation allows the truck bed to be rotated from a horizontal to a tilt position so that the truck cab and bed are in the same relative relationship in the horizontal position as before the installation of the hoist, i.e. the hoist does not alter the original body lines of the truck. The hoist is a four bar linkage. The yoke utilizes one cylinder to operate a scissors of wide pivotal area but narrow at its mountings. The wide pivotal area permits use of the space around the truck differential since the scissors side plates and spreader plate straddle the truck differential and permit a heavier payload to be lifted. The wide pivotal area enables the hoist to be used with essentially all standard pickup trucks and makes the hoist effectively universal.

Abstract: A stove device attachment for a conventional lantern having a fuel reservoir, a glass globe enclosing a mantle which is illuminated by fuel from the reservoir, and a central connection for a draft hood. The attachment is connected to the top of the lantern by removing the ferrule or nut from the central connection for the draft hood positioning the attachment over the draft hood so that the central connection extends through a hole in the top plate or stove surface of the attachment, and replacing the ferrule or nut on the central connection. The attachment comprises three elements, a shield, a stove surface, and a skirt. The skirt is a tubular metal member which fits over the draft hood. The stove surface or grate fits over the skirt and the bottom surface of the grate is secured within the top of the skirt. The shield is secured to the back of the grate.
