Abstract: A wind turbine gear box arrangement having one or more bearings located in a single region along the longitudinal axis and arranged to provide support between an input shaft and a non-rotating support component. The one or more bearings are arranged to at least partially restrict non-rotational movement between the input shaft and the non-rotating support component. A portion along the longitudinal axis between said input shaft and the non-rotating support component is bearingless outside the single region.

Abstract: A gear arrangement including a first gear arranged to rotate about a first longitudinal axis and including a first plurality of gear teeth, and a first portion including a first surface and a second gear arranged to rotate about a second longitudinal axis and including a second plurality of gear teeth, and a second portion including a second surface. The first surface and the second surface are arranged to abut one another and restrict relative non-rotational movement of the first gear and the second gear.

Abstract: A method and apparatus for removing volatile organic contaminants from soil and waste materials including transporting and placing the contaminated material into a hopper, the hopper being substantially sealed from the atmosphere to prevent fugitive emissions of the contaminants from escaping into the atmosphere; conveying the material under substantially sealed conditions into a heated vapor stripping conveyor; conveying material under substantially sealed conditions along the vapor stripping conveyor to heat the material and thereby cause moisture in the material and the contaminants to be stripped from the material; streaming non-oxidizing gases at a controlled temperature over the material, in the direction of travel of the material, beginning at a point downstream of and adjacent to the introduction of the material into the vapor stripping conveyor to carry the contaminants and moisture away from the material; and maintaining the rate of flow and temperature of the gases to prevent undue surface drying o

Abstract: Method and apparatus for removing organic contaminants from contaminated materials including a sealed hopper, a heated vapor stripping conveyor sealed from atmospheric air to vapor strip the contaminants from the material, a sealed conveyor to convey the material in sealed condition from the hopper to the vapor stripping conveyor, a supply of non-oxidative gases at a controlled temperature for introduction into the vapor stripping conveyor, an introduction portal for the non-oxidative gases into the vapor stripping conveyor, an exit for removing the non-oxidative gases from the conveyor and located to cause the non-oxidative gases to cross currently sweep over the material to convey contaminants and moisture stripped from the material out of the vapor stripping conveyor, and a controller for controlling the flow rate and temperature of the non-oxidative gases as they flow through the vapor stripping conveyor and to prevent undue surface drying of the material as the material passes through the vapor stripping
