A continuous output system makes paper coating by combining an emulsifier with ASA particles having sizes in the low to sub-micron region. A turbine, pump, blender or other device exposes the ASA to a number of repeated episodes of high shear until the resulting ASA is in the form of particles having a mean average diameter in approximately the 1.mu. range. A manifold provides the system piping in order to minimize the internal areas where ASA may build up. This manifold has a plurality of holes bored in a solid metal block so that each of the bores forms a short pipe which is only an inch or two in length in order to reduce the interior surface area of an ASA transport and conveyance system.

[The claimed invention is:] [1.]A. supplying a liquid including at least ASA;B. feeding a portion of said liquid of step (A) to a first input of a manifold;C. feeding a first stream of an emulsifier into a second input to said manifold, said liquid combining with said emulsifier within said manifold

[The claimed invention is:] [1.]A. supplying a liquid including at least ASA;B. feeding a portion of said liquid of step (A) to a first input of a manifold;C. feeding a first stream of an emulsifier into a second input to said manifold, said liquid combining with said emulsifier within said manifold to form a first stream comprising a mixture of at least ASA and said emulsifier;D. feeding the first stream of step (C) through a mixing means which imparts enough energy to said emulsion to shear and break down said ASA into particles and divide an outflow from said mixing means (i) through a recycling loop to at least a third input of said manifold and (ii) to an output stream of said system, said output stream having a ratio of ASA to emulsifier set by the relative volumes of said streams of Step (B) and Step (C); andE. feeding said recycled emulsion of step (D) into said mixing means of step (D).
