Abstract: A solid lubricating composition useful for lubricating the flanges of railcar wheels and rails and for other similar applications. The lubricant composition comprises from about 16% to about 25% by weight of a polymeric carrier, from about 49% to about 63% of a lubricating oil, from about 10% to about 16% of a solid lubricating powder, and from about 6% to about 16% of a surface active agent, all percentages by weight of the total composition. The solid lubricant composition is mixed and introduced into a screw type extruder wherein it is heated and extruded through a die into a waterbath, forming an elastic rod or strand. The lubricant composition is applied to a surface to be lubricated by rubbing it onto the surface in a thin film. The surface active agent enhances the attachment and embedment of the dry lubricating powder into the surface being lubricated, the lubricant composition serving to reduce both wear and friction between contacting surfaces lubricated thereby.

Abstract: A new membrane for the separation of aromatic hydrocarbons from mixtures of said aromatic hydrocarbons and non-aromatic hydrocarbons has been prepared comprising a highly aromatic polyurea/urethane membrane. These highly aromatic polyurea/urethane membranes are symmetric, dense film membranes made from the corresponding polyurea/urethane copolymers by standard membrane casting techniques. The polyurea/urethane copolymers are produced by reacting dihydroxy or polyhydroxy compounds, such as polyethers or polyesters having molecular weights in the range of about 500 to 5000 with aliphatic, alkylaromatic or aromatic diisocyanates or polyisocyanates and low molecular weight chain extenders, such as diamines, polyamines or amino alcohols.

Abstract: The octane requirement increase phenomenon in a spark ignition internal combustion engine is controlled by introducing with the combustion charge a fuel composition containing an octane requirement increase-inhibiting amount of a combination of compounds, the combination comprising a first compound being (1) a gasoline soluble amide and (2) a second compound being a gasoline soluble ketone. Usually the first and second compounds are each added to the fuel in an amount between about 0.001 and 3 weight percent of the fuel. In particular, the combination of N,N-dibutyl formamide and either benzophenone or methylcyclohexanone provides an effective octane requirement increase-inhibiting additive for unleaded gasoline.
