ABSTRACT:
An enclosed container for transporting a powdered material is aerated by a pressurized gas which is forced between a long sheet of flexible, gas-impervious material and a sloping surface of the container. The sheet material is held in place by a pair of clamps which accurately control the size of the space through which the gas flows so as to cause the sheet material to vibrate or flutter over a relatively long distance.
