Abstract: A rotating lubrication applicator is provided for metered lubrication of machine parts including parts of drive mechanisms. The preferred applicator includes an inner hub and an outer lubricating portion. The outer lubricating portion is made out of a solid lubricant containing microporous polymeric matrix material. Tensioning devices including the rotating lubrication applicators are also provided as are methods of using the same. The applicator will provide a metered amount of lubricant to surfaces which come into contact with outer lubricating portion.

Abstract: An apparatus and a method for lubricating an edge dam in a twin-roll type strip casting machine are disclosed. A continuous uniform lubrication boundary layer is formed on the friction face between the casting rolls and the edge dam, so that the wear of the edge dam refractory material can be reduced, and that the friction faces of the casting roll can be protected, thereby improving the performance and the durability of the machine. The apparatus includes a lubricant spouting nozzle disposed adjacently to a friction face of the casting roll, and a lubricant supplying device for supplying a lubricant to the lubricant spouting nozzle so as to make the lubricant spouted and adhered on the friction face of the casting roll. Further a lubricant spreading roller is installed at a rear of the lubricant spouting nozzle, for pressing the lubricant onto the friction face of the casting roll with a certain pressure so as to make the lubricant clad on the friction face. The method includes the following steps.

Abstract: A liquid metering and coating assembly for use in a thermal toner fixation unit of a plain paper copier or printer. The assembly consists of a release oil-supply roll having a compliant and flexible porous permeation control layer and a cleaning blade. The cleaning blade is mounted so as to contact the surface of the permeation control material. The cleaning blade removes excess toner and other incidental debris from the surface of the permeation control layer thereby providing a freshly cleaned surface from which controlled amounts of release oil are uniformly coated onto the surface of an adjacent contacting roll.
