scharge, turn anticlockwise to increase discharge; reassemble hand wheel pin and lead-seal it after adjustment. Common failure and Troubleshooting The main failure of four-piston measurement transducer includes outside leakage and accuracy decline. As appear outside leakage, all seal sections should be inspected. Generally, failure will be solved through removing damaged or aging sealed components. Diagram 2-22: working principle of four-piston measurement transducer Through long time of operation, the accuracy of measurement transducer is declined due to various abrasion occurred on cam, ideal wheel, distributing valve, valve seat, and piston. From start, regulating adjusting wheel makes the accuracy meet the requirements about national metrology appraisal. If still can’t reach the wanted accuracy, some abrasion examinations should be conducted, including components of piston, distributing valve and valve seat. These components surfaces are fragile to be scratched by hard grain, increasing inner leakage and accuracy decline. If appear above situation, replace piston or grind the surfaces of distributing valve and valve seat. Double soft piston measurement transducer The article will introduce the structure, working principle and maintenance. Structure This type of measurement transducer has two soft pistons, smaller than four-piston type. Appearance and partial cutaway view is illustrated in Diagram 2-23, structure and key components in Diagram 2-24. Diagram 2-23: Cutaway view and figure of four-piston measurement transducer It has two pistons formed a 120 degree angle, driven by connecting rod that force crankshaft moving. Component cylinder is installed in parallel. The two rolling bearings respectively installed on connecting rod and crankshaft reduces the friction. The end of connecting rod con fuel dispenser tacts with bushing. The oil discharge is controlled by distributing valve that co fuel dispenser mmunicating with inlet and outlet. On the top of distributing valve mounted a bearing used for installing cranks fuel dispenser

that central junction box. However unlike the normal passive primary junction box it　　 provides an electrically separate drive for each connected cable segment. The LON　　 network is therefore split into a number of smaller networks each of which is more　　 tolerant of cable performance. It is advised that for maximum tolerance of poor　　 cabling each IFSF device is directly cabled to the active hub as in Appendix C.1.　　 As well as enabling the re-use of existing cables the use of an active hub also has　　 some key advantages: there is no need to test existing cables; there is individual　　 isolation to each device; and site manager s level diagnostics are provided (a simple　　 blinking light to each device to show it is alive). The only supplier currently known to　　 the IFSF with an active hub is BT Electronics for further information access URL　　 www.btelectronics.com.　　 Note 1: the wiring topology shown in Appendix C.3 can only be used if both ends of　　 each loop return to the same port on the active hub and not as shown in the diagram　　 to adjacent ports.　　 Note 2: When installing an active hub each section of the smaller networks must be　　 correctly terminated as described in 3.4. The BT Electronics active hub is provided　　 with switchable terminators on all ports.　　4.7 Other Considerations　　4.7.1 Cable Cross-section　　 Some of the cables given in Appendix B have an oval or elliptical cross-section.　　 Please note that this can cause sealing problems when installed in dispensers. Cables　　 with a circular cross section are preferred.　　4.7.2 Cable Rigidity　　 Some of the cables given in Appendix B are very difficult to bend. In some　　 instal fuel dispenser lations particularly into the back of a Personal Computer (PC) the movement of　 fuel dispenser 　 the PC or navigating tight corners has resulted in the fuel dispenser

from the ground up. If that does not merit the Nobel Peace Prize, I cannot imagine what does. Nicholas Colloff Alcester, Warwickshire SIR - You wrongly suggest that anti-poverty campaigners are different from peacemakers. Giving impoverished women financial power is more courageous than any wartime peacekeeping negotiations. The violence and hardship that Grameen’s operations alleviate makes it a worthy winner.

The most enduring conflict of the past century, between Israelis and Palestinians, drags on drearily today. The first wars of the 21st century have also unfolded there, in Afghanistan, Iraq, western Sudan and Lebanon. This being so, the West has a long history of espying new spectres in the region. In the 1950s and 1960s it was Nasser, Egypt s passionate pan-Arabist leader. In the 1970s it was Palestinian terrorism; in the 1980s Khomeini s Islamic revolution; since the turn of the century, al-Qaeda-style mayhem; and now again revolutionary Iran, newly expansionary and perhaps, some day, armed with nukes. Some of these imagined threats to the global order have been leftist and nationalist, some reactionary and religious, some radical and violent. Yet all have drawn their mobilising power from a single source. They have all been, in essence, resistance movements, inspired fuel dispenser by a seemingly unquenchable popular urge to challenge the dominant perceived inj fuel dispenser ustice of the day, whether it be European colonialism, Zionism, American hegemonism or the grip of local gover fuel dispenser
