at least one outlet from said mixing chamber, and
a pair of control ports at said upstream end of said oscillation vortex
mixing chamber such that said jet of carrier liquid entrains fluent material
alternately from said control ports,
and passages for coupling said pair of control ports to one or more fluent
material source for mixing by vortex-action in said oscillation vortex mixing
chamber with said jet of carrier liquid prior to exiting from said oscillation vortex
mixing chamber through said at least one outlet,
whereby when said jet of carrier liquid entrains fluent material from said
control ports, said jet of carrier liquid oscillates and oscillation of said jet of
carrier liquid stops when entrainment of fluent material through said control ports
ceases.
