    • An adjustable air-deflector device adapted to be movably mounted on the roof of a driving cab of a commercial vehicle and comprising a substantially planar member having the shape of a truncated isosceles triangle, the shorter parallel edge of which is hinged to the cab roof, and the non-parallel edges of which are connected to the cab roof through adjustable bellows-type side walls, there being angle-adjustment means provided to allow the driver of the vehicle to adjust the angle of the planar member relative to the cab roof to produce minimal drag over a trailer portion of the vehicle. Driver determines optimum angle either from a table of predetermined figures or from a drag pressure metering instrument mounted in the cab of the vehicle. Air-deflector device can be used in a tractor-trailer assembly in combination with adjustable side curtains, which close the gap between the tractor and trailer and reduce the component of drag produced by yaw between the moving tractor and trailer.
    • 一种可调节的导风装置,适于可移动地安装在商业车辆的驾驶室的顶部上,并且包括基本上平面的构件,其具有截短的等腰三角形的形状,其较短的平行边缘铰接到驾驶室车顶, 并且其非平行边缘通过可调节的波纹管型侧壁连接到驾驶室车顶,设有角度调节装置,其被设置成允许车辆的驾驶员将平面构件相对于驾驶室车顶的角度调节到 在车辆的拖车部分产生最小的拖动。 驾驶员可根据预定图形的表格或安装在车辆驾驶室内的拖曳压力计量仪器确定最佳角度。 导风装置可用于拖拉机 - 拖车组件中,与可调节的侧帘组合使用,可缩小拖拉机和拖车之间的间隙,并减少运动拖拉机和拖车之间由偏航产生的阻力分量。

    • We disclose a process for purification of hydrocarbons, suitable for a wide range of contexts such as refining bunker fuels to yield low-sulphur fuels, cleaning of waste engine oil (etc) to yield a usable hydrocarbon product, recovery of hydrocarbons from used tyres, recovery of hydrocarbons from thermoplastics etc, as well as the treatment of crude oils, shale oils, and the tailings remaining after fractionation and like processes. The method comprises the steps of heating the hydrocarbon thereby to release a gas phase, contacting the gas with an aqueous persulphate electrolyte within a reaction chamber, and condensing the gas to a liquid or a liquid/gas mixture and removing its aqueous component. It also comprises subjecting the reaction product to an electrical field generated by at least two opposing electrode plates between which the reaction product flows; this electrolytic step regenerates the persulphate electrolyte which can be recirculated within the process. The process is ideally applied in an environment at lower than atmospheric pressure, such as less than 1500 Pa. A wide range of hydrocarbons can be treated in this way. Used hydrocarbons such as engine oils and sulphur-contaminated fuels are prime examples, but there are a wide range of others such as hydrocarbons derived from the pyrolysis of a material having a hydrocarbon content. One such example is a mix of used rubber (such as end-of-life tyres) and used oils (such as engine oils, waste marine oils), which can be pyrolysed together to yield a hydrocarbon liquid which can be treated as above, and a residue that provides a useful solid fuel.
