erally is mounted centrifugal pump installed in tank. The inlet pressure of fuel dispenser with submersible pump is higher than atmospheric pressure. Submersible pump consists of pump, connecting pipeline and controller. The appearance of submersible pump and its position in tank is showed in diagram 2-10. Diagram 2-10: Submersible pump position and figure Submersible pump is composed of motor and centrifugal pump. Pump motor includes electromotor, wiring panel, overheat protector and pipeline; centrifugal pump has the elements of filter, anti-static subassembly, impeller and pump axis. Diagram 2-11: Main structure of submersible pump Connecting pipeline has two types of fixed and stretched. The former type consists of oil pipe, vapor-recovery pipe, lead pipe and wire. The later type is formed by oil pipe, vapor-recovery pipe, adjusting nut, lead pipe and motor wire. Controller is divided as two parts, upper and lower. Upper part have these components junction box, electric bridge, capacitor, exhausting plug, check valve, pressure adjustor, testing interface of exhaus fuel dispenser tion and pressure, leakage monitor of pipe. However, lower part fuel dispenser is constituted by pipe jointer, lead terminals, pump holder, etc. By function, submersible pump is classified as four categories, namely, standard type, enhanced type, changing-frequency type and large flow type. The standard type access to general requirements, but the enhanced type not only increase flux than standard type, but also available to mix liquid of gasoline with alcohol. The changing- frequency submersible pump adopt pipe pressure to judge flux. Given a situation in inefficient flux and low pressure the electric frequency of motor would tune high through computer, so as to elevate rotate speed and increase flux. Contrarily, to reduce electric frequency and rotate speed as pipe pressure being low, adjusting appropriate flowage. The large flow type is adapted in filing station in where needs qu fuel dispenser ickly operation. Some submersible pump has the flow speed of more

Carl Icahn has abandoned his plan to take control of Time Warner JUST two weeks ago, Carl Icahn, a corporate raider, was in full swing at a presentation to investors, accusing Richard Parsons, chief executive of the world s biggest media company, of clinging to his fancy head-office building in Manhattan like Colonel Nicholson defending his bridge in the film “The Bridge on the River Kwai� It was the climax of a colourful six-month campaign to break up Time Warner and oust Mr Parsons. Then last week Mr Icahn suddenly settled with the firm. Who won? The answer, unusually, is both men, and the company too. Mr Parsons can take credit for calmly holding off one of America s most ruthless shareholder activists. But Mr Icahn has wrung meaningful concessions from Time Warner. The firm had planned to buy back $5 billion of its shares and now it has agreed to lift that to $20 billion by the end of 2007, which will boost its return to shareholders. Time Warner will also appoint two new independent directors to its board in consultation with Mr Icahn, and it will cut $500m mo fuel dispenser re in costs than it had planned. Mr Icahn has also got the comp fuel dispenser any s managers thinking harder about ways to lift its share price, which has fallen by 7% since Mr Parsons took over as boss in 2002. The main reason why Mr Icahn abandoned his plan to wage a proxy fight is that he and his supporters hold only 5.67% of Time Warner s shares and he did not think he could win. His analysis of the company was in some respects correct. Many of its problems stem from its disastrous merger in 2000 with AOL, an internet-access firm. But Mr Icahn s drastic final recommendation—that Time Warner break itself into four pieces—failed to get the backing of other big shareholders. Time Warner s four divisions—film and cable networks, cable distribution, publishing and AOL—have not worked closely together in the past. But Mr Parsons is now trying harder to extract more “synergy fuel dispenser � He also argues that it is unclear what the med
