(under subclass 518) Device including means to increase or decrease the rate at which the grain passes a given point in the device.
(1) Note. The means of this subclass are usually located near the entrance or exit of the hulling zone; and, responding to the weight of volume of grain restrict the flow of grain, or, allow the grain to move at an increased rate of flow.
SEE OR SEARCH THIS CLASS, SUBCLASS:
