A fine azimuth adjustment tool and method for a satellite antenna system having a clamp with opposing jaws for clamping around the mast pipe, a lever connected to the clamp for opening and closing the opposing jaws; a cam with a protrusion engaging a formed slot in the mast clamp when said opposing jaws are closed, the protrusion rotating the mast clamp when the cam is turned, the protrusion in the slot holding the mast clamp to the mast pipe at a desired fine tuned azimuth position while the mast clamp is tightened and secured to the mast pipe.

A waste-to-energy conversion apparatus comprising a primary combustion chamber capable of holding a load of waste, and the primary combustion chamber further comprises a heat source to heat the waste and generate a syn gas stream, grates, within the primary chamber, capable of supporting the load of waste during heating, a mixing chamber wherein the syn gas is mixed with additional combustion gas, a multi-chambered secondary combustion chamber for combusting the mixture of syn gas and additional combustion gas, and an energy extraction system for extracting the heat energy generated by the combustion of the mixture of syn gas and additional combustion gas.

An air-starved, batch burn, modular, municipal waste incinerator. It is designed to oxidize unsorted loads of heterogeneous materials in quantities ranging from 5 to 500 tons per 12 to 15 hours. The unique aspect of this system design is that through research in air mixing, air turbulence, and temperature control, it is possible to burn this material with a highly favorable stack emission product, without the need for bag houses, dry scrubbing, or other elaborate down stream air processing equipment. The incinerator includes a primary combustion chamber connected to a secondary combustion unit by a gas transfer tube. Solid material in the primary is oxidized--or gasified--without live flame. This flammable gas stream is vented into the secondary for ignition. Combustion gases from the primary chamber are completely burned in the secondary combustion unit as the gases pass upwardly through the air mixing ring and tangentially disposed re-ignition burners.
