acklist, etc. Once found something wrong, it will obtain latest data from Center controller. Anti-low temperature The minimum limitation of working temperature is �0℃on general fuel dispenser. But on IC card fuel dispenser,�0�due to employ temperature control device. Turn on the device when necessary. Apart from the above functions IC card fuel dispenser should be provided with these traits such as explosion-proof electric safety, anti-dust, anti-interference, high applicability of power supply, high reliability, low ratio of failure, convenient for combination and expansion. Article IV Fuel dispenser and reader working flow Refueling process Under normal situation, filling process should be like this: When power supply is connected, the whole system begins to initiate. As CPU get open command (nozzle has switched on) motor is startup; small flux solenoid valve switch on, oil flowing out of nozzle; CPU calculates volume filled according to pulse transmitted by sensor; at same time, large flux solenoid valve is open, being large filling state. Metering circuit counts paid volume and money on basis of pulse sign transmitted by flow sensor, then transmit these data and unit price into CPU that control the display of current filing. Metering CPU, if in randomly filing, will switch off solenoid valve and motor to end filing when receive stop sign (nozzle has switched off). If in presetting filing process, metering CPU will firstly close large flux solenoid valve when paid volume approaching to presetting volume (100ml~~300ml), small flux solenoid valve being open until paid volume is equivalent to presetting volume. Finally, current filing information such as filled volume, money and unit price (PPU) is transmitted into CPU and display on screen. The proportion of large flux to small flux is 10 to 1. The knowledge of fuel dispenser’s normal working procedure is of importance to judge trouble and failure.

of his remit was to keep it out of the news. With the public finances tightening, however, and passenger numbers continuing to rise, that is getting harder. One way to improve things would be to spend railways existing cash more rationally. Stephen Grant, a rail consultant, points out that rural services receive 60% of the subsidy but account for only 16% of passenger kilometres travelled. “A lot of these trains are maintained to the same standard as 90-mph main-line services,�he says. “But all they do is potter up and down a branch line all day.� Some fear the government is considering more radical measures than lighter maintenance. New laws proposed last year included provisions for closing down underused lines. Though ministers say they have no immediate plans to do so, rail boosters fear the spectre of Dr Beeching, the man who axed nearly a quarter of the system 40 years ago. They defend rural trains on the grounds that these provide vital transport links for the poor and carless. So, though, do bus services, and at a fraction of the cost. Closing little-used, expensive lines would free money to spend on carrying passengers into cities rather than moving fresh air around the countryside. Old lines can be re-used as cheaper light-rail systems, or paved over and converted into bus-ways, an idea that is being tested in Northamptonshire. Even without all that, says Mr Grant, closing a line can bring more benefits than costs. He points to the Camel Trail, a popular cycle path and bridleway in Cornwall that runs along the bed of an old railway. Its value as a tourist attraction, he says, is much higher than it would be as a railway line.  © 2006 .  About sponsorship Northern Ireland Peace dropping slow Jul 6th 2006 | BELFAST From The Economist print edition A small step towards reconciliation IN SEPTEMBER, builders permitting, 20 families, including Catholic Protestant couples and immigrants, will move in fuel dispenser fuel dispenser fuel dispenser
