rmance, and full-category. Article III Basic function and category Basic functions of fuel dispenser Refueling oil to vehicle and measuring the oil fueled is the basic function of fuel dispenser. Oil or fuel referrers to light fuel, such as automotive light kerosene, vehicle gasoline. Fuel dispenser, of course, also can be used to refuel other oil like above that relative to viscosity and physical and chemical capacity. Its measurement is in conformance with the requirement on measuring accuracy. The whole working process of fuel dispenser should be ensured because the operation medium mainly is flammable liquid, and working circumstance has combustible substance. It is obvious that delivery fuel, measurement and work safety are the basic requirements and functions to fuel dispenser. Apart from the above functions fuel dispenser has other ancillary functions, such as environmental function and oil-air recovery function. Chinese fuel dispenses have many functions, including taxation data record, memory and investigation, readout IC card, presetting fuel, communicating with upper network, or subject to upper control, receipt print, etc. with the evolution of dispensing method, the ancillary function undertake many variety, which mirrors the major improvement of fuel dispenser. fuel fuel dispenser dispenser’s category Fuel dispenser can be divided into various categories according to its configuration and function. It is divided into mechanical fuel dispenser (Diagram 1-3, 1-14), and electronic fuel dispenser (displayed and operated by electronic components) according to counter indicator and operation configuration. Owing to the inherent defects of mechanical counter and operation, mechanical fuel dispenser has rapidly been replaced by the electronic one, commercial fuel dispenser in particular. There are the general fuel dispenser�40-60L/min. and large flowage fuel dispenser with 80-90L/min in terms of delivery capacity. By the number of fuel unit and nozzle mounted, fuel dispenser include single nozzle fuel dispenser fuel dispenser

regions,�says Mr Tesseyman, who meets plenty of them. These are admirable aims, but clearly they are not going to be achievable by all banks. The alternative ambition� and perhaps the real aim of every private bank in Russia bar one or two—is to sell out to foreigners at a fancy price. Now that Impex has sold for almost three times book value, sellers of the bigger private banks are going to be arguing for four times or more. How about a listing? For larger private banks, fancy prices may also be available through the stockmarket. Sberbank has enjoyed a long run as the only listed Russian bank stock with any liquidity. Its shares have been much in demand, tripling last year (see chart 8). That left Sberbank trading at 20 times historic earnings this year, much higher than most commercial banks. Other Russian banks want to follow if the markets hold up. Analysts say that Rosbank may go this year, and that Vneshtorgbank and Gazprombank, both state-controlled, may list minority stakes next year. Buyers will have to proceed with caution. Russian assets are no longer cheap, and Russian banks are moving targets. Loan portfolios are growing fast, but there are not nearly enough data to model the risks, and such few as are available have been collected during an economic boom. fuel dispenser Credit quality may look very different when a downturn hits. At best, says Richard Hainsworth, who runs a bank credit-rating agency called RusRating, “we can look at the experience of other countries, we can make the assumption that the Russian population will behave in a similar way, but that assumption is tendentious, to say the least.� Nor is the Russian government s behaviour all that easy to predict. In principle it welcomes free enterprise and foreign direct investors. In practice it hates any loss of administrative control over industries it considers of strategic value. One issue holding up Russia s bid to join the World Trade Organisation has been the government s refusal to ease restrictions o fuel dispenser fuel dispenser
