dicator is installed between nozzle and measurement transducer, by which customer observes whether foam in delivering oil. Accuracy will be affected because of much foam or bubble. Diagram 2-33 is shown a common oil indicator in domestic market. Since this kind of oil indicator has big pass section than that of two ends of pipe, velocity of flow of passing oil is reduced so as to facilitate observation. If oil transparent, that is, no foam in it, fuel dispenser is in normal state. If opaque with visible foam, it is shown that there is gas in oil. Don’t refuel until foam disappears in oil indicator. If passed long time, foam in oil indicator still exists so that the accuracy of fuel dispenser is affected, some troubleshooting measures on vapor separator should be considered. Disassemble low cover and examine gasket and joint face if found leakage. Oil in pipe should be discharged completely in maintenance, keeping appropriate tightness to bolt fuel dispenser s as reassembly in case of crunching glass. 1-Frame 2-Sink-screw 3-Seal gasket 4-Glass 5-Seal 6-Cover Diagram 2-33: Ball-shaped oil indicator structure Columnar oil indicator, shown in Diagram 2-34, is installed on the top of gantry fuel dispenser, the convex end connected with pipe jointer of fuel dispenser, the concave end of it with hose unit. Foam is observed through the glass pipe of columnar oil indicator. If found leakage, disassemble oil indicator from jointer, clean waste or replace damaged gasket. Replace glass pipe when found crackle on it. Be careful of reassemble hose jointer and oil indicator after maintenance in case of crunch glass pipe. 1-Frame 2-Glass pipe 3-Seal ring 4-O-ring Diagram 2-34: Columnar oil indicator Firstly empty oil in fuel dispenser when deal with oil indicator’s trouble, for fear of oil spl fuel dispenser ashing. There is a kind of method to empty here: loose bolt on corrugated pipe after start up fuel dispenser. In this state, no oil in tank is suck into fuel dispenser, but oil in fuel dispenser is discharged out continually. After stop fuel dispenser

2006 From The Economist print edition How one rural community hit it lucky THE village of He Hua in Wenzhou municipality, about 365km (225 miles) south of Shanghai, is a typically bizarre product of China s bipolar economy with its rigid distinction between urban and rural. A stranger looking at its streets lined with shops, restaurants, office blocks and apartment buildings would have no idea that it is a village at all. It looks just like any other urban area of Wenzhou, one of China s most prosperous cities. The rapid outward expansion of Chinese cities in recent years has swallowed many villages like He Hua, which 20 years ago was an expanse of paddy fields. Sometimes the land is appropriated by the government and sold on to developers, with some of the money being used to rehouse the villagers who are reclassified as urban residents. But often villages have remained villages, looking urban but governed by different economic fuel dispenser rules. He Hua is one of those. The He Hua village office, down a shabby alleyway next to a luxury housing development, is now the headquarters of a property company that is making good use of the village s virtual existence within Wenzhou s urban sprawl. These “villages within cities� as they are called, can take advantage of urban housing demand to rake in fortunes with their remaining plots of collectively owned land. And if the villagers are lucky, as they are in He Hua, they will get a generous share of the money. He Hua s village committee is just about to redesignate itself as the He Hua Village Economic Shareholding Co- operative, a process that has taken four years. The elected village chief has become its general manager. The village s former Communist Party leader is now chairman of the board. All this has take fuel dispenser n a long time to organise because assets had to be valued and, most contentiously, shareholders identified. Only villagers can be shareholders, but it was not easy to decide how to deal with villagers who had moved elsewhere and wante fuel dispenser
