210, Liquid Purification or Separation,

360.1+, for a centrifugal extractor of that class.

494, Imperforate Bowl: Centrifugal Separators, appropriate subclasses for apparatus for breaking up a mixture of fluids or fluent substances into two or more components by centrifuging within a generally solid-walled, receptacle-like member. If utilized for treating textiles, however, an imperforate bowl, centrifugal extractor, per se, is not in Class 494, but, rather, is in this class (68), inasmuch as the treating of textiles is not within the scope of that class (494), if on the other hand, the centrifugal extractor

is perforate in nature, it may be proper for Class 210, noted above.
