Abstract: A tank cleaning machine comprising a housing having an inlet and a stationary guide diverter disposed within the housing. A gearing mechanism is attached to the stationery flow diverter. A nozzle extends from the housing wherein the nozzle is in fluid communication with the inlet and the nozzle includes an inclined portion extending from a horizontal portion of the nozzle. A drag limiter extends into a hydraulic fluid reservoir to limit the rotation speed of the gear.

Abstract: A continuous waste to energy partial oxidation gasification system and process is accomplished with high pressure.

Abstract: A cutting blade includes a connection portion for connection to a cutting head for rotating the blade, preferably in association with other blades being rotated with the cutting head. The blade body also includes a blade body portion with a leading edge with a cutting blade portion and an upper leading surface and lower leading surface extending from the leading edge to an upper transition zone and lower transition zone respectively. A upper trailing surface extends from the upper transition zone to a trailing edge and a lower trailing surface extends from the lower transition zone to the trailing edge. The upper and lower trailing surfaces converge such that the blade body portion is hydrodynamically shaped. According to a further embodiment, the cutting blade has a sickle shape.
