Abstract: A device for injecting at intermittent periods a dispersion of a liquid at controlled pulsing periods into exhaust fumes of a combustion engine, said liquid contains a component which reacts with a component of the exhaust fumes at a catalytic converter, said device comprises a housing containing a first chamber a means for supplying the liquid into a first chamber a means for pumping the liquid from the first chamber into a pressure swirl atomizer where the liquid is dispersed, said swirl atomizer comprising an outlet nozzle leading the dispersion into an exhaust manifold through which the exhaust fumes are directed prior to being converted at the catalytic converter, said device further comprises a means for controlling the means for pumping such that a pulsing period during which the liquid is injected into the swirl atomizer is controlled to be from about 1 to about 1000 milliseconds as well as a method for injecting a dispersion of a liquid into exhaust fumes of combustion engines.

Abstract: The present invention relates to methods of using an aqueous composition or dispersion containing a water-soluble or water-dispersible synthetic polymer, and compositions formed thereof. The aqueous composition or dispersion is added to agricultural spray compositions, ink compositions, deicing or anti-icing compositions, latex paint and coating compositions, cleaner compositions, adhesives, fire-extinguishing chemical compositions, hydro-metallurgy/electro-winning compositions, compositions having organosilanes, personal care compositions, water-based hydraulic compositions, dust control compositions, and textile finish compositions, to impart properties including aerosol control, spatter control, shear stability, rheology control, transfer efficiency, oil/water reduction, sling control, emollient performance, film forming capability, surface activity, encapsulent ability, lubricity, thickening, and anti-wear capability, to the resultant composition formed thereof.
