    Abstract: A feeder for an extruder includes a feed flow passage extending in an axial direction from a feeder inlet to a feeder outlet, and an axially extending rotatable screw provided in the feed flow passage. Rotation of the screw draws a feedstock in a direction of flow to the feeder outlet. The feeder inlet has an inlet passage that overlies the screw. The inlet passage has a width in a plane transverse to the axial direction, and the width decreases in the direction of flow.

    Abstract: A surface cleaning apparatus comprises an air treatment chamber with a moveable member positioned therein. An end wall of the air treatment chamber is openable in response to a moveable member being longitudinally translated through at least the portion of the air treatment chamber. The driving assembly includes a handle and a drive rod that is rotatably mounted about a longitudinally extending axis of the drive rod between a stored position in which the moveable member is in a stored position and an operable position in which the moveable member is translatable through at least a portion of the chamber. In the stored position, the handle is longitudinally spaced from the first and second ends of the air treatment chamber and, when the driving assembly is in the operable position, the driving assembly is operable to longitudinally translate the moveable member through at least a portion of the chamber.
