Abstract
A pusher is disposed to drive material out of a dispensing outlet and extends into a first chamber that is configured to contain a hydraulic fluid disposed to drive the pusher. A second chamber is configured to exchange hydraulic fluid with the first chamber. A fluid control mechanism is disposed between the first chamber and the second chamber. Air under pressure is applied to urge a rapidly transforming material to flow toward one portion of a bifurcated chamber from another portion of the bifurcated chamber. The driven rapidly transforming material is allowed to drive a material from a dispensing outlet. At least a portion of the rapidly transforming material is caused to physically transform to a form that is more resistant to flowing. The dispensing outlet is caused to change position. At least a portion of the rapidly transforming material is caused to physically transform away from the form that is more resistant to flowing.
