Abstract: A magnetic recording medium, comprising a substrate, a magnetic recording lamina and at least one sulfonamide wherein the at least one sulfonamide is present in an amount sufficient to provide desirable tribological properties. A process for lubricating magnetic recording media comprising applying at least one sulfonamide to a surface of the magnetic recording media or incorporating at least one sulfonamide into the lamina of the magnetic recording media.

Abstract: A magnetic recording media containing a lubricant which is a cyclic phosphazene completely substituted with fluorinated phenoxy substituents and m-perfluoroalkylphenoxy substituents, in ratios ranging from 1:1 to 1:5 is disclosed. The recording media and lubricant are particularly useful for advanced, high density magnetic recording media.

Abstract: Cyclic phosphazenes completely substituted with fluorinated phenoxy and m-perfluoroalkylphenoxy moieties in ratios ranging from about 1:1 to about 1:5 are disclosed. These compounds, either alone or as additives, are useful as high temperature lubricants.

Abstract: The invention is a filter apparatus and method for separating suspended solids from fluids, particularly liquids. A filter chamber is defined inside a filter housing. Inside the chamber is a filter bundle, consisting of two or more filter screens, of a non-woven construction. Spaces between the filter screen strands provide channels for fluid to flow through the filter bundle along a tortuous path that is parallel to each screen. These spaces also define openings for directing a flushing fluid, such as air, in a crosswise direction through the filter screens. The crossflow path of the flushing fluid removes solid particles trapped in the channels of the filter screens.

Abstract: An improved electrical plug household use to protect household occupants from electrical shocks while inserting or removing the plug from an electrical receptacle. The plug, in general, is a standard household electrical plug with or without a ground prong. The improvement of the present invention is to mount an elastically collapsible electrically insulating hood on the plug surrounding the prongs so that when the improved plug is inserted more than half way into the household electrical receptacle, the extent of the prongs not yet within the receptacle is surrounded by the hood and inaccessible to contact by household occupants, especially children. The hood can be a plastic bellows integrally molded with the body of the plug or the hood can be formed separatly and glued to the body of the plug. The hood can also be a foamed polymer tube section glued to the body of the plug.

Abstract: Crystalline aluminates conforming substantially to the general formula LiR.2Al(OH).sub.3, CaR(A).2Al(OH).sub.3, or ZnR(A).2Al(OH).sub.3, where R is an organic acid of C.sub.6 -C.sub.22 and A, when present, is an inorganic anion, are found to improve the coefficient of friction and antiwear properties of lubication fluids subjected to shearing, rubbing, or grinding forces at elevated pressure.

Abstract: Crystalline lithium stearate aluminate improves the coefficient of friction, the antiwear properties and the extreme pressure properties of lubricating fluids.
