Pump forces material through restriction (e.g., static emulsifier):
(under subclass 150.1) Subject matter wherein the feed means is in the form of a pump for forcing the material through a narrow restriction for the purpose of mixing the material, particularly for the purpose of emulsifying or homogenizing the material.

160.2+, 181.8, and 182.2, for a mixing chamber having a pump for feeding material to it.
181.5, for a flow-through mixing chamber having a stationary deflector for agitating the material.
336+, and particularly 340, for mixing apparatus in which material is divided into different portions by passage around deflectors or through apertures therein and recombined for the purpose of mixing or emulsifying the material.

138, Pipes and Tubular Conduits,
40+, for a conduit having a restriction that modifies the flow of fluid through the conduit. 516, Colloid Systems and Wetting Agents; Subcombinations Thereof; Processes of Making, Stabilizing, Breaking, or Inhibiting, appropriate subclasses for subject matter relating to: colloid systems (such as sols*, emulsions, dispersions, foams, aerosols, smokes, gels, or pastes) or wetting agents (such as leveling, penetrating, or spreading); subcombination compositions of colloid systems containing at
least an agent specialized and designed for or peculiar to use in making or stabilizing colloid systems; compositions and subcombination compositions specialized and designed for or peculiar to use in breaking (resolving) or inhibiting colloid systems; processes of making the compositions or systems of the class; processes of breaking (resolving) or inhibiting colloid systems; in each instance, when generically claimed or when there is no hierarchically superior provision in the USPC for the specifically claimed art.
