Abstract: This invention relates to oil soluble, nitrogen containing sulfonated polymers useful as additives for lubricating oil and fuel oil, which are effective as dispersants and viscosity modifiers. The polymeric dispersant additives are ionic polymers which comprise a back-bone substantially soluble in the fuel or lubricant, and pendant ionic groups which are sulfonic acid groups which may be neutralized with an ammonium cation or an amine. Polymeric dispersant additives of this type may be made which are particularly useful in crankcase lubricating oils for imparting viscosity improvement, varnish inhibition, oxidation inhibition and detergency to the lubricant. These additives may also impart rust preventive properties to the oil or fuel, and as V.I. improvers they can be formed to have particularly good low temperature viscosity effects in lubricating oil.

Abstract: Apparatus for mixing and dispensing multiple fluids utilizes two fluid reservoirs (18, 20) each in fluid communication with a respective pump (54, 64) for pumping the fluids to a mixing head (50). Means (70) drive the pumps at respective speeds inversely proportional to the respective viscosities of the fluids and are arranged to pump the fluids from the reservoirs at a predetermined volume ratio. A pressure switch (58) is provided for measuring fluid pressure to the mixing head (50) and stopping the pumping of fluid at a predetermined maximum pressure while starting the pumping of fluid when the fluid pressure falls below the predetermined maximum pressure. A device (96, 98, 88) for detecting an empty fluid reservoir is used to stop the pumping of fluids to avoid single component pumping. A mechanical torque-releasable coupling (72) is used to disconnect the pumps (54, 64) from the pump drive (70) in the event of an internal pump overload.
