Abstract: An improvement has been found in a continuous grease process. A saponification reaction product is continuously recycled through both a shear valve and a heat exchanger to produce a dehydrated grease of uniform consistency and temperature. Both recycle loops are controlled by means of a single shear valve.

Abstract: Railroad wheel flange lubricating is carried out with a lubricating composition which is particularly useful in a locomotive-mounted applicator. The water base lubricant comprises a compatible blend of two polyoxyalkylene glycols, one a synthetic lubricant and the other a synthetic thickener. The lubricating composition is persistent and environmentally innocuous.

Abstract: A continuous process for manufacture of soap thickened grease compositions where a saponifiable material and a metal base are continuously introduced at an elevated temperature into a saponification zone maintained at superatmospheric pressure and saponified under turbulent conditions, wherein the saponified product is mixed with an aqueous solution of oil-insoluble additive materials at a superatmospheric pressure sufficient for maintaining all water in the liquid phase, wherein the saponified material-additive mixture is heated to an elevated temperature of at least 350.degree. F.

Abstract: A grease may be made having synergistic extreme pressure properties using a major amount of a base oil and a thickener and a minor amount of low density polyethylene and known extreme pressure enhancing additives.
