VP500B with power showed in Diagram 4-4. As the simplest design, it could be installed at end of reclaiming pipe, namely, near to tank and inlet. It can simultaneously reclaim 12 nozzles, applicable to fuel dispenser with suction pump or submersible pump. Center-type reclaiming vacuum pump VP500B without power showed in Diagram 4-5. This type of pump is very applicable to city filling station, which is powered by submersible pump, mounted 8 nozzles of reclaiming. The deployment of vapor pipe and air vent of tank ensures station’s normal operation. Distributed reclaiming vacuum pump: each fuel dispenser is mounted vapor reclaiming vacuum pump. Diagram 4-6: VP vacuum pump Diagram 4-7: Separated jointer Diagram 4-8: Coaxial hose S fuel dispenser eparated jointer: its main function is used as convert jointer to separate vapor and oil. Repeated use breakaway: used for protecting fuel dispenser in case of pull down by vehicle. As exterior pull reaching 310~350lb, breakaway is automatically closed, at same time switch off pipelines of vapor and oil. Coaxial hose: a kind of hose with two layers that delivery vapor in internal and exterior oil. Nozzle: with double-layer pipes, mounted vapor valve. Fuel dispenser with vapor recovery system This kind of fuel dispenser with vapor recovery function is used for reclaiming volatile oil vapor near outlet without affecting normal refueling. There are two types widely adopting in domestic market, one is the new developed fu fuel dispenser el dispenser that has vapor recovery function; the other type is improved fuel dispenser based upon traditional dispenser and added vapor recovery function. Generally, these are divided into two categories: submersible type and built-in pump type. Diagram 4-9: Vapor recovery nozzle Submersible fuel dispenser with vapor recovery function If adopt vacuum-aid vapor recovery system, the matching fuel dispenser with vapor recovery function should adopt submersible fuel dispenser. Its working principle is that center vacuum pump g fuel dispenser

but a placeman s rant, but it unleashed the whirlwind. More articles followed, attacking public figures in the name of party purity. A Great Proletarian Cultural Revolution took shape, especially on university campuses, where students were recruited for a new “shock force� the Red Guards. From January 1967 factories, banks and power plants were seized nationwide, while the Red Guards and the army sought out, terrorised or simply killed all deviants from orthodoxy. What role Mr Yao played in all this is difficult to say. He was in charge of propaganda so the hate-filled articles, the staged “free debates� the “big-character�posters and banners and cartoons, may have had some origin with him. So may the use of Mao s quotations, handily bound in a littl fuel dispenser e red book. But it seemed to some that Mr Yao was a puppet, not a master; that he went along happily, even sadistically, for the ride, and was swept up in the horror. On Mao s death, in 1976, the Gang of Four s already waning primacy ended with arrest and disgrace. At his trial, Mr Yao was mostly silent, managing only to stutter that the words in his diary did not represent his views. He received the lightest sentence of the four, 20 years in Qincheng prison. There he was glimpsed occasionally, a small, very bent figure in an all-grey Mao suit. He still kept his diary, and was said to be writing a book. So much self-reflection he could manage. China s rulers could not, and cannot. They had no interest in what he mig fuel dispenser ht write or say; after his release they allowed no one to speak to him, and even his death, announced two weeks late, was an embarrassment. China still has no way of coping with the trauma that Mr Yao s article helped unleash one which Mao, a national hero, inspired, and in which millions joined. © 2006 . Overview Jan 12th 2006 From The Economist print edition Stockmarkets had a good week.
