DEFINITION

Classification: 494/47

Including means for imparting other movements to bowl in whole or in part before, during or after its axial rotation:

(under subclass 43) Apparatus which includes means for moving the member, or at least one portion thereof relative to another portion, in some manner other than its customary turning about its principal axis, and wherein the means may act either during the time the member is turning or prior to or subsequent to such time.

(1) Note. If the means acts during rotation of the member, the other movement probably plays a part in the separating function; if, on the other hand, the means acts at some other time, the other movement is likely to be for a purpose not directly related to the separating.

(2) Note. For the purposes of this subclass, vibration is considered to constitute movement.

19, for a separator which includes a plurality of miniature bowls (e.g., test tubes) which are distributed about a rotatable carrier and are readily removable therefrom and wherein means is provided for rotating each bowl about its own axis, also.

33, for a separator which includes a plurality of separate and distinct bowls and wherein the bowls are equally spaced from a central axis for rotating about that axis, also.

46, for a separator having a rotatable bowl which includes bearing means adapted to enable the bowl to establish a dynamic axis of rotation, the result of which may be a slight lateral shifting of the axis and, therefore, of the bowl.
