As past over long service time, parts abrasion universally or cylinder severely damaged, a new measurement transducer should be installed to replace old one. As find exterior leakage, firstly inspect the bolts corre fuel dispenser sponding to leak section. Tightly screw loose bolts, if leakage is continued, disconnect and inspect the seal ring and gasket relative section. Substitute aging or damaged parts and reassemble. Apart from the above reasons of extensive colloid and surface abrasion, these trouble also cause abnormal operation of measurement transducer, such as position pin fall down from piston or deformation, small axis lost on upper and lower connecting rod, loose bolt between piston and connecting rod. The solution is that disassembling measurement transducer, replace damaged or unqualified components and reassemble. The products made in normal factory seldom appear these troubles. Since measurement transducer is core component of fuel dispenser, elaborate machining, disconnection and reassembly should be as careful as possible. All elements should be cleaned before reassembly, excluding water into inner. Bolts are tightened even and appropriately. Soft-piston measurement transducer As these merits --- small in size, light weight, beautiful appearance, high accuracy, pi fuel dispenser ston exchangeable--- soft-piston measurement transducer is widely adapted in domestic fuel dispenser market. It generally involves two structures: four-piston structure and double-piston structure. The latter model is selected universally. Therefore, this article will introduce the structure, working principal and maintenance of four- piston measurement transducer. Structure Diagram 2-20 and Diagram 2-21 show the cutaway view and exploded drawing of four-piston measurement transducer that is widely employed. The transducer mainly consists of sealed cover, upper subassembly, export axis, frame subassembly, piston subassembly, connecting rod and top cover, clearly presenting in Diagram 2-20 and Diagram 2-21.

uck Business School s Centre for the Study of Private Equity and Entrepreneurship. Whilst some funds, such as Providence Equity Partners and Elevation Partners, have long focused on media, some of the big, genera fuel dispenser list funds have lately been hiring expertise. Carlyle, a possible buyer of Tribune, recently recruited Norman Pearlstein, a former editor-in-chief of Time Inc, to help identify suitable targets. Private equity may mean better management. Since Cox Communications, a cable firm, went private in 2004, it has benefited from the lack of both short-term market pressure and Sarbanes-Oxley-related interference. KKR has installed a highly-regarded former GE executive to run the hitherto poorly managed VNU. But cutting costs can be hard. The Philadelphia Inquirer snew private-equity owners found themselves facing a possible strike after they tried to lay off workers. America s tough restrictions on cross-ownership of different media businesses may pose a further obstacle to restructuring. Private equity s biggest advantage today is its access to vast quantities of debt, on what old-time bankers might regard as recklessly generous terms. They can borrow at far higher multiples to earnings than the public stockmarket is willing to sustain. That makes it hard fuel dispenser for public companies to compete against private-equity buyers. It s a nice position for private equity, but also dangerous. Mr Bloomberg is said to be convinced that private-equity is overpaying, and that when they later face pressure to deliver returns, they will slash jobs to boost short-term profits. He does not want that fate for Bloomberg. Other media owners may be less troubled by such prospects and more interested in cashing in on the seller s market of a lifetime. © 2006 .  About sponsorship BP Beyond coincidence Nov 2nd 2006 From The Economist print edition Critics detect a pattern in BP s recent woes “WHAT BP experienced wa fuel dispenser
