DEFINITION

Classification: 494/17

And means for introducing either material or auxiliary fluid into bowls:

(under subclass 16) Apparatus which includes also means for feeding either (a) the material which is to be separated or (b) one or more fluids, which fluid or fluids are not initially a part of the material to be separated, to the members.

(1) Note. While not initially a component of the material supplied for separation, the fluid of this subclass sometimes becomes an indistinguishable part of either the material or a separated component thereof.

(2) Note. Typical of the art of this subclass is the supplying of a liquid for "washing" a sample of blood.
