Abstract: A scarfing torch adapted for manual manipulation which includes means disposed in said torch to provide a component of force upon the torch to offset forces upon the torch generated either by the flow of oxygen gas used in the scarfing process or gravity. The offsetting force is provided by the release of a secondary fluid from the torch in the appropriate direction. The secondary fluid may be released to impinge upon the surface of the workpiece being scarfed.

Abstract: A conveyor system which is particularly suitable for moving large very heavy dense loads such as steel coils. The conveyor includes a stationary portion and a movable portion which is raised and moved forward to move the load forward. The movable portion is then lowered, so that the load is supported on the stationary portion, and moved backward to be in position for another movement of the load. The movable portion is supported on air bearings during the forward and return steps to reduce friction. The disclosed conveyor can be used for moving loads a relatively long distance, often over 1000 ft. (304.9 meters). Thus, for a practical device low friction operation is necessary. Adjustable guides are provided so that the movable load support can be accurately positioned with respect to the stationary load support. Air lifting units are provided for raising and lowering the movable load support. Hydraulic cylinders are provided for moving the movable load support back and forth.

Abstract: A white rust inhibited composition is comprised of a zinc containing substrate. A white rust inhibiting composition contacts the substrate and is comprised of a vapor corrosion inhibitor and a pH adjusting compound to adjust and maintain the pH of the white rust inhibiting composition between 8 and 12.5.
