e hydraulic pulse so as to increase inner discharge of measurement transducer, affecting fuel dispenser’s accuracy. The incorrect pipeline installation makes the whole hydraulic system much unstable --- pressure pulse increases. As higher oil temperature or vacuum pressure, oil viscidity will reduce, affecting measurement transducer in two facets. One is to increase inner leak, the other is to decline the stability of hydraulic system. From above analysis, it is known that high vacuum pressure of pump inlet is not always good for fuel dispenser’s normal operation. One pipe connect to several fuel dispensers Some filling stations, in order to reduce installation cost, adopt one pipe to connect several fuel dispensers, which is very unscientific. In this type of installation there would be brought two facets of troubles: one is that, as some fuel dispensers stop operations, some still work, air would be suck from stopped dispensers so as to affect the accuracy of working fuel dispensers. The other trouble is that if several fuel dispensers work at same time, there would be mutually interfering, increasing flow pulse and inner leakage so as to affect accuracy. 1.2 Pipeline installation in positive pressure Delivery oil through positive pressure refers to in delivery process the inlet of fuel dispenser is positive pressure, which is adopted in the following situations. One is that delivery oil from high position tank, the other situation is tat adopt submersible pump in tank to delivery oil to fuel dispenser. The latter situation is more often. The Article 6.2.6 in GB501 fuel dispenser 56-2002 the Design and Construction of Vehicle Filling station stipulated that if several fuel dispensers adopt same one pipe, each is affected and lead to uneven influx. Therefore, in order to ensure accuracy, the pipeline between fuel dispenser and tank should scientifically design and installation, using as few as elbow, keeping inner wall smooth of pipe. These are beneficial to reduce pressure and electricity loss, and to decl fuel dispenser fuel dispenser

rty-insurance contract with foreign reinsurers and simultaneously cut its cost, prompting prospective competitors to grumble that the monopolist is still throwing its weight around. Mr Lisboa retorts that IRB is cutting costs and preparing for competition. Chile s reinsurance monopoly shrank, but survived after liberalisation, Mr Lisboa notes. South Korea s still dominates its market. IRB may end up specialising, for example in dealing with smaller insurers that foreign giants overlook. The “main beneficiary� Mr Lisboa acknowledges, should be the market as a whole. © 2006 . Economics focus The long and the short of it Jan 5th 2006 From The Economist print edition America s bond market is upside down. Is the economy about to capsize as well? SHORTLY before America s last recession, which began in March 2001, something odd happened to interest rates. Short-term rates rose above long. The same thing happened before the recessions of 1990, 1981, 1980, 1973, 1969 and 1960. A dark omen, then, but why worry about it now? In recent months, yields on short-term securities have crept up on those offered by longer-dated instruments. In the last week of December, it was (slightly) cheaper for the American government to borrow for ten years than for two. This is unusual. The government borrows by selling a variety of IOUs, which promise to give the buyer his money back sooner (three-month bills, for example) or later (eg, ten-year Treasuries). Normally, the longer the maturity, the higher the yield a security must offer the “yield curv fuel dispenser e�slopes upwards. Markets take this to be the natural state of affairs (though just why it should be so has taxed some of the best economists). When things are upended, the yield curve is said to be “inverted� a condition now exciting much chatter among analysts. Despite all this talk, the yield curve is not yet inverted across its full length. The yield on two-year Treasuries may have risen above that on ten-year b fuel dispenser fuel dispenser
