DEFINITION

Classification: 494/57

Element associated with pickup of material and adjustable for varying quality of flow:

(under subclass 56) Apparatus comprising an element which is related to the gathering of material that is to be conducted out of the member and which element is repositionable or otherwise adjustable for changing the ratio of the lighter component or components to the heavier component or components in the material gathered.

(1) Note. The repositioning ordinarily involves movement in a direction radially of the member.

(2) Note. The element may be merely the free end of a pickup tube, which end can be relocated in a radial direction. In another instance, the element may be a perforated cover for the end of such a tube, which cover is threadedly engaged with the tube and may be moved radially of the member by changing the amount of its threaded engagement with the tube. In still another instance, the element may be an externally- threaded bushing having an axial passage and threadedly engaged with an aperture in the wall of the member, and wherein, in the instance of vertically-oriented member, (a) a horizontally-arranged bushing may be rotated about its axis to vary its distance from the axis of the member, or (b) a vertically-arranged bushing, having its passage eccentric of its axis, may be rotated about its axis for varying the offset of its passage from the axis of the member.

(3) Note. Occasionally, the regulation of the quantity of material exiting from the member at one or more locations may be utilized to vary the quality of material departing from the member, the departure usually taking place at a location or locations other than the first mentioned one or ones. Art of this nature may be found in subclass 56 above.

(4) Note. Although the art of this subclass sometimes identifies the adjustable element as a "paring device" or "skimmer," this subclass is by no means residual to such a component.
