Diagram 1-15: Mobile fuel dispenser Diagram 1-16: Vehicle-mounted fuel dispenser Diagram 1-17; Hanging filling system Diagram 1-18: Card-controlled fuel dispenser In addition, according to special ancillary function, there are mobile fuel dispenser (Diagram 1-15), vehicle-mounted fuel dispenser (Diagram1-16), hanging filing system (Diagram1-17), fuel dispenser with vapor recovery device (Diagram1-7), mixed product fuel dispenser available to change product label (Diagram1-10), fuel dispenser communicated with upper network (Diagram1-12), fuel dispenser subject to upper network (Diagram1-11), card-controlled fuel dispenser (Diagram1-18), etc. Article IV Basic working principle and configuration of fuel dispenser Basic working principle. The basic working principle of fuel dispenser can be illustrated by the following chart 1-19, the line with arrow presenting flow direction of oil, line denoting the transmission direction of mechanical or electric sign. Diagram 1- 19: Working process of fuel dispenser Fuel is sucked from underground tank, enter measurement transducer via vapor separator, and flow out nozzle through solenoid valve. The position movement value of axis generated fuel dispenser by transducer is fuel dispenser converted into relevant electric pulse sign by sensor, the indicator of electric counter display accumulative volume refueled. If in mechanical fuel dispenser, the volume refueled can be presented by the indicator device of mechanical counter by measuring the position movement of output axis of converter. The pump of submersible fuel dispenser is installed in oil in tank, which can delivery fuel to several measurement transducers, and flow out nozzle. Its counter device is similar to pump built-in fuel dispenser. The current fuel d fuel dispenser

And all, with the possible exception of Georgia, see closer ties with the EU as a way of diversifying risks rather than antagonising Russia. This is one of those occasions when the EU can be more influential than its constituent parts. Germany, France or Britain can do comparatively little to contain Russian meddling. An EU of 25 and still growing can remind Russia that its “near abroad?is also Europe s neighbourhood. © 2006 .

Apart from election campaigns, when rising support for far-right political parties in areas such as Dagenham causes alarm, the traditional working class is largely overlooked.
