hen distributing valve gets into a certain degree, another set of cylinder and piston are discharging and inputting. Under varied oil pressures four pistons has accomplished a circulation, camshaft and exporting axis rotating a circumference. Oil volume in a circulation is a stable constant. Diagram 2-22 illustrates the working circulation of four—piston measurement transducer. Working in Diagram 2-22a: high pressured oil flow into Cylinder 4 via the outboard of distributing valve, impelling Piston 4 move toward center. Piston 4 drives Piston 2 moving through connecting rod, at end of cylinder the oil is flowed out from the inside port of distribut fuel dispenser ing valve. Meanwhile, roller drives cam rotating clockwise, by which impel distributing valve moving. As both of them rotate at the 45 degree, operation fuel dispenser goes into Diagram 2-22b state. Operation in Diagram 2-22b: as the time when Piston 4 and Piston 2 continue inlet and discharge, respectively, cylinder 1 and cylinder 3 start to inlet oil and discharge. Roller 4 and Roller 3 together drive cam rotating clockwise, as cam and distributing valve turn around 45 degree, operation goes into Diagram 2-22c state. Operation in Diagram 2-22c: as the time when Piston 1 and Piston 3 continue inlet and discharge oil, respectively, cylinder 1start to drive cam rotating clockwise. When cam and distributing valve turn around 45 degree, operation goes into Diagram 2-22d state. Operation in Diagram 2-22d is same to that of in diagram 2-22a. Diagram 2-22: Working principle chart of four-piston measurement transducer Discharge adjustment Fuel dispenser has passed the discharge adjustment so as to meet the accuracy requirement. Due to mechanical abrasion in long period of operation real discharge would deviate from academic discharge, resulting in accuracy decline. As the deviation appears, adjusting discharge could satisfy the accuracy requirement. The detailed adjustment methods as follow fuel dispenser ed: at the beginning pull out the pin on hand wheel, turn wheel clockwise to reduce di

pling the POS application from the EPS application whatever architecture is adopted:　　EPS manages payment POS manages selling with no implication on each other.　　A device proxy component enables the two applications to manage the access to peripherals sharing the　　peripheral when convenient and maintaining the conceptual independence.　　Platform independence is a key requirement.　　1.2 Introduction　　The XML interface we wish to define is that shown in the attached diagram.　　 POS　　 Selling　　 fuel dispenser This Interface　　 EPS　　 Electronic Payment　　 fuel dispenser Service　　 Authorisation　　There are three main configuration types:　　 1. The EPS application and the POS applications insist on the same indoor point of payment. They　　 might be combined into one piece of hardware or in different machines; because some sites have　　 more than one point of payment according to the resilience requirements and to the system design　　 different options are possible. Both the POS and the EPS applications might use the peripherals　　 claiming temporary exclusive use.　　 2. The EPS is in a stand alone Credit Authorisation Terminal (CAT). The CAT has all of the Card　　 Handling Device peripherals attached to it including a display keyboard and printer. This implies a　　 physical separation of the two applications POS and EPS. Usually this scenario is demanded by　　 proprietary bank card environment.　　 3. The EPS and POS peripherals are attached to a Customer Operated Payment Terminal generally　　 outdoor (OPT). In this instance all cashier operat fuel dispenser ions are automated by the POS applicat

more closely mimic human responses. This offers the opportunity to understand human diseases better, and to screen treatments before human trials begin. However, the very creation of these mutants counts as an animal experiment in its own right, so the number of experiments is increasing once again. What is bad news for rodents, though, could be good news for primates. Apes and monkeys belong to the same group of mammals as humans, and are thus seen as the best subjects for certain sorts of experiment. To the extent that rodents can be “humanised� the number of primate experiments might be reduced. Some people, of course, would like to se fuel dispenser e them eliminated altogether, regardless of the effect on useful research. On June 6th the British Union for the Abolition of Vivisection, an animal-rig fuel dispenser hts group, called for the use of primates in research to be banned. For great apes, this has already happened. Britain, Austria, the Netherlands, New Zealand and Sweden have ended experiments on chimpanzees, gorillas, bonobos and orang-utans. Experiments on monkeys, though, are still permitted. And some countries have not banned experiments on apes. In America, for example, about 1,000 chimpanzees a year are used in research. This is a difficult area. Great apes are man s closest relatives, having parted company from the human family tree only a few million years ago. Hence it can be (and is) argued that they are indispensable for certain sorts of research. On the other hand, a recent study by Andrew Knight and his colleagues at Animal Consultants International, an animal-advocacy group, casts doubt on the claim that apes are used only for work of vital importance to humanity. Important papers tend to get cited as references in subsequent studies, so Mr Knight looked into the number of citations received by 749 scientific papers published as a result of invasive experiments on captive chimpanzees. Half had received no fuel dispenser t a single citation up to ten years after their original publication. That is damn
