dicator is installed between nozzle and measurement transducer, by which customer observes whether foam in delivering oil. Accuracy will be affected because of much foam or bubble. Diagram 2-33 is shown a common oil indicator in domestic market. Since this kind of oil indicator has big pass section than that of two ends of pipe, velocity of flow of passing oil is reduced so as to facilitate observation. If oil transparent, that is, no foam in it, fuel dispenser is in normal state. If opaque with visible foam, it is shown that there is gas in oil. Don’t refuel until foam disappears in oil indicator. If passed long time, foam in oil indicator still exists so that the accuracy of f fuel dispenser uel dispenser is affected, some troubleshooting measures on vapor separator should be considered. Disassemble low cover and examine gasket and joint face if found leakage. Oil in pipe should be discharged completely in maintenance, keeping appropriate tightness to bolts as reassembly in case of crunching glass. 1-Frame 2-Sink-screw 3-Seal gasket 4-Glass 5-Seal 6-Cover Diagram 2-33: Ball-shaped oil indicator structure Columnar oil indicator, shown in Diagram 2-34, is installed on the top of gantry fuel dispenser, the convex end connected with pipe jointer of fuel dispenser, the concave end of it with ho fuel dispenser se unit. Foam is observed through the glass pipe of columnar oil indicator. If found leakage, disassemble oil indicator from jointer, clean waste or replace damaged gasket. Replace glass pipe when found crackle on it. Be careful of reassemble hose jointer and oil indicator after maintenance in case of crunch glass pipe. 1-Frame 2-Glass pipe 3-Seal ring 4-O-ring Diagram 2-34: Columnar oil indicator Firstly empty oil in fuel dispenser when deal with oil indicator’s trouble, for fear of oil splashing. There is a kind of method to empty here: loose bolt on corrugated pipe after start up fuel dispenser. In this state, no oil in tank is suck into fuel dispenser, but oil in fuel dispenser is discharged out continually. After stop fuel dispenser

ple a token of　　 value 2 (02H) is used.　　 1801 0208 02 42 0008 0100 04 01 14 05 01 E5　　 The correct acknowledgment would be　　 0208 1801 00 E2 0007 010005 0400 0501　　 If we wrote it the other way around i.e. block length first and then heart beat interval.　　 Then the following write and acknowledge message would be generated. In this　　 example a token value of 3 (03H) is used.　　 1801 0208 02 43 0008 0100 05 01 E5 04 01 14　　 Acknowledgment 0208 1801 00 E3 0007 010005 0501 0400　　5.3 Read and Write Data Error Handling　　 When an appplication decides to read or fuel dispenser write a message there is a definate sequence　　 (priority) to the error handling.This chapter concerns only the processing of data and　　 not commands. The priority sequence is as follows ?once the first error has been　　 detected no further error processing is required.　　5.3.1 Communication Layer Errors　　 Firstly with both read or write message an MS_Ack of 1 is returned if the recipient　　 physcial node is unreachable. This means the application cannot find on the network　　 the physcal node address of the destination. An MS_Ack of 2 is fuel dispenser returned if the　　 physical node address is reachable but the logical node cannot be addressed.　　 At this point we know that we are addressing a working logical device. The next level　　 of validation is whether the device is locked. An MS_Ack of 9 is returned is the　　 device is locked.　　 We now have a unlocked logical application. The communication layer will alert the　　 application if the device is busy (MS_Ack=7).or if there are any missing blocks　　 (MS_Ack=3). MS_Ack=7 has precedence over MS_Ack=3 because a device that is　　 busy generates an error after the first received frame. The I fuel dispenser

re therefore inclined to view taxes benignly, as public investment. The state, after all, still has a Allen, all backwoods relatively modest per capita tax burden, ranking 41st among the 50 states. Mr Allen, by contrast, fancies himself as an anti-tax hawk. The right wing of his party likes that, as it does his opposition to abortion, his difficulties with homosexuals and his near-blind allegiance to George Bush on Iraq. The newer sort of Virginians, however, see him as an inflexible partisan. As he balances his Senate re-election campaign with his drive for the presidency, Mr Allen may discover that the issues dear to the conservative core of his party mean little to Vi fuel dispenser rginians in general. Mr Warner has the opposite problem. His centrist opinions—for the death penalty, for some abortion restrictions, against gay marriage, against further gun control—endear him to Virginians but put him outside the mainstream of the national Democratic Party. Still, he views himself as the anti-Hillary, positioned to snatch the nomination if Mrs Clinton stumbles. It seems that Mr Warner could have run a different race, for Mr Allen s Senate seat. Polls show he would now win it easily, though in 1996 he failed in a Senate bid. But he might have found himself in the same sad situat fuel dispenser ion described by Mr Allen in a recent interview with the New York Times running for president to escape the sheer boredom of Senate life. © 2006 . Refugee policy Less hope, a longer wait Apr 27th 2006 From The Economist print edition America is treating more refugees as terrorist suspects JUST as the United Nations Refugee Agency (UNHCR) is reporting that the world s refugee population has fallen to 9.2m, the lowest for 25 years, the agency has also sounded a note of alarm.
