. Presetting refuel and non-presetting refuel Fuel dispenser’s hose is full of oil in non-presetting refueling progress. Due to the function of solenoid valve in presetting refuel progress, hose is not full as that of non-presetting. Only one refuel mode is adapted in appraisal progress because hose cubage directly affect accuracy of fuel dispenser. Oil Volatility The working media of fuel dispenser always is volatile, vehicle gasoline in particular. Oil volatilization inevitably affect the appraisal result, therefore, it is prohibited to conduct test in large wind or high temperature whether. Chapter VII Failure and Troubleshooting Like any other machinery, fuel dispenser unavoidably appears failure during long time of operation. it is not a simple thing in maintenance progress as judge the trouble part or reason. Since fuel dispenser is composed of varied mechanical, electronic and hydraulic components, a failure maybe caused by diverse reasons or a same reason result fuel dispenser in different trouble. In addition, fuel dispenser operates with other exterior devices --- outside power network, tank, delivery pipeline, etc, which also generating abnormal working -- rather than independently. Therefore, fuel dispenser’s functional failure is just phenomenon, mechanical failure is root reason. Only know working principle and structure firstly, can repairer correctly judge failure reason and solve trouble. In order to do that the academic knowledge is needed to support, to learn the relation between causation and phenomenon, and ceaselessly summarize practical experience. In short, as for fuel dispenser’s failure, preventive guideline and strict safety operation regulation, should be carried out, enforcing regulative maintenance and inspection, getting rid of trouble within burgeon state. Owing to various models and struct fuel dispenser ure in domestic fuel dispense market, specific type should be maintained in accordance with the User’s Manual, the handbook only presents the common failure and troubleshooting of genera fuel dispenser

cts of political parties on both left and right. Often, as the whiff of mouldy politics wafts from the mainstream parties, the beneficiaries are on the political fringes, notably the far-right National Front. Jean-Marie Le Pen, the front s leader, has been quick to capitalise on the mainstream right s woes, lamenting the “state lies�of a “banana republic�government. The more complex the Clearstream affair seems, the harder it will be for ordinary voters to determine who is in the right—and the more likely it is that they will conclude that the whole lot are rotten. © 2006 . France and immigration Let the skilled come May 4th 2006 | PARIS From The Economist print edition A shift towards more selective immigration “IF CERTAIN people don t like France, they shouldn t hesitate to leave.�With this echo of a notorious National Front slogan, Nicolas Sarkozy, the French interior minister, transformed the immigration bill that he put fuel dispenser before parliament this week into an exercise in populism. But behind the rhetoric is a sensible change, towards a managed, high-skilled, demand-led immigration policy. AP Stealing Le Pen s clothes Until the mid-1970s, most immigrants to France came to work. Since the law was tightened in 1974, the inflows have changed. Today, only 7,000 permanent workers arrive a year, down from over 170,000 in the late-1960s. Three-quarters of legal entrants to France are family-related spouses, children and sometimes extended families of those already in the country. France has a low proportion of skilled immigrants. Mr Sarkozy s bill aims to reverse this trend, by introducing selective immigration. There will be yearly targets fuel dispenser for three categories of incomers workers, students and families. Skilled migrants will be encouraged through a new three-year “talent�work permit. The bill includes measure fuel dispenser
