Appeal 2007-1678
Application 09/800,547
I. BACKGROUND
As in the previous appeal, the invention relates to a process for
making a dressing and the dressing made. Since the prior appeal, Appellants
have amended claim 1, the only independent claim. Claim 1 is illustrative of
the subject matter on appeal. We reproduce claim 1 below emphasizing the
differences from the prior claim 1 on appeal by italicizing the additions and
bracketing the deletions:
1. A process for making a dressing comprising the steps of:
(a) combining raw ingredients comprising an oil phase and an
aqueous phase in a pre-mix tank comprising a means for mixing to form a
coarse emulsion, and
(b) processing the coarse emulsion in a single [one] pass through an
in-line mixer/emulsifier comprising at least one set of stator and rotor, and
an adjustable [a variable] speed motor to drive the rotor, wherein the stator
and rotor comprise co-axially engageable rings of teeth having a plurality of
concentric vanes and concentric wells with generally slanted side walls from
each vane to each well and the rotor and stator when engaged are such that
the concentric vanes of the stator align with the corresponding concentric
wells of the rotor and the concentric vanes of the rotor align with the
corresponding concentric wells of the stator with the corresponding
generally slanted walls of the stator and rotor aligned and when engaged a
gap having an axial opening dimension and slanted opening dimension is
defined by each concentric vane and each concentric well and the aligned
slanted walls and the gap is adjustable in increments of about 0.015 inches in
axial opening dimension,
wherein said axial opening dimension is about 0.010 inches to about
0.500 inches;
wherein the diameter of the stator and rotor is about 9 inches or
more;
