Abstract: A snow plow runner for supporting the blade of a snow plow above the abrasive surface of a roadway with the snow plow runner formed of a material of a first melting temperature and having a plurality of hardened pads formed of a material of a similar melting temperature to permit fusing the pads to the snow plow runner to provide a high abrasion resistant surface that permits the snow plow runners to be used over an extended period of time.

Abstract: A replaceable cutting blade assembly for a dozer is designed to present at least three, and optionally four, potential working edges.

Abstract: An apparatus for removing slag during torch cutting of a metal work plate by an oxyacetylene torch which is remotely programmed to cut a predetermined pattern in a metal plate. The molten metal slag particles fall through an upper and lower section of a conveyor belt and onto the floor of a tank filled with water. The lower section of a continuous moving conveyor belt transports the slag along the floor of the tank to a disposal area. The workpiece which is cut from the metal plate drops into the tank but is prevented from falling to the floor of the tank by the top section of the conveyor belt. The top section of the conveyor belt transports the workpiece to a finishing area. Movable and adjustable members are provided for supporting the work plate during the cutting operation.
