Compaction methods and apparatus
First Claim
1. Compacting apparatus comprising a screw conveyor for conveying waste material through a passage and compacting it therein, an exit nozzle communicating with the passage, the nozzle defining an internal transverse cross-sectional area which enlarges and reduces and which comprises at least one selectively variable and adjustable resilient member which sets the nozzle to be biased towards and maintains a specifically desired cross-sectional area within its range of enlargement or reduction to achieve compaction substantially independent of increasing and decreasing waste material pressure.

Abstract
Waste compaction apparatus has a screw conveyor which conveys material along a passage toward an exit nozzle which constricts the flow, to cause compaction. The screw conveyor is slidably mounted on a shaft, biased toward the nozzle. This allows the screw conveyor to move axially during compaction to help remove or avoid blockages within the apparatus.
