Abstract: A method and apparatus for removing coatings and oxides from substrates that includes a conveyor for moving a substrate in a first direction, at least one nozzle positioned away from the conveyor in position to direct the stream of fluid toward the conveyor and a high pressure fluid supply in fluid commination with the nozzle wherein the pressurized fluid supply is arranged to supply a pressurized fluid to exit the nozzle and direct the fluid at a high velocity to a surface of the substrate for removing a liquid or solid film from the substrate. The method includes providing a pressurized fluid to a stationary nozzle, directing the pressurized fluid from the nozzle in a high velocity fluid stream toward a moving object having a coating and contacting the fluid stream with the object whereby a force of the fluid removes the coating.

Abstract: Method, system and apparatus are disclosed for in-vessel composting of organic material. A compost handling apparatus moves forwardly through a bed of composting material in an elongate open bay. Specifically, an agitator comprises a feed belt such as a transversely mounted cylindrical drum, which feeds composting material to a conveyor which lifts the material and projects it rearwardly behind the agitator. A regulator, such as an adjustable deflector, controls the discharge of composting material by the conveyor. The deflector is adjusted as the agitator moves forward through the composting material to develop a level bed in the bay behind the agitator. A sensor may be employed to generate a depth signal corresponding to the depth of the composting material for controlling the deflector.
