Abstract

See full text

Free space within a chamber is filled with a flowable material via an opening in a surface of the chamber. A delivery force is used to deliver the flowable material into the chamber via the opening. An outwardly directed force, independent of the delivery force, is applied to draw the flowable material away from the opening. The extent to which the free space within the chamber has been filled is sensed. And the delivering of the flowable material is controlled in response to the sensing. A wall of the chamber defines a longer dimension and a shorter dimension and the opening is in a portion of the wall that defines the longer dimension. The flowable material is delivered into the chamber via the opening in a manner such that, as the flowable material fills the chamber, a surface of the flowable material moves toward the opening along the longer dimension of the chamber. The approach of the surface of the flowable material toward the opening is sensed as an indication of the extent to which the free space within the chamber has been filled.
