fuel dispenser haft. The spring between top cover and distributing valve is used for enforcing sealability. The two gears synchronous to crankshaft moving transmit rotation number into pulse sensor. Working principle This type measurement transducer is similar to a set of hydraulic motor, which is driven by pressured oil. Thus, the discharge is corresponded to the crankshaft rotation. As distribut fuel dispenser ing valve’s position is certain when oil flowing into measurement transducer, the piston discharge or inflow also is constant. Pistons depend upon the different oil pressure of inflow and discharge to move, which form a shuttle movement. The above two pistons movements c fuel dispenser reate a third cylinder, which also has a 120 degree angle. The dynamic working circulation is showed in Diagram 2-25. As the diameter and moving distance of piston is certain, the relation between movement and crankshaft rotation also fixed. In every two times inflow or discharge of piston, crankshaft turn around a circle, oil volume in inlet or outlet progress is constant. 1-Piston 2-Crankshaft 3-4-Connecting rod 5-Screw 6-Bearing 7-Bushing 8-Frame 9-Distributing valve 10-Top cover 11-Bearing 12-Spring 13-14-Gear 15-Adjusting bolt 16-T-shaped key 17-Sider cover Diagram 2-24: Structural drawing of four-piston measurement transducer Diagram 2-25: Working principal drawing This type of measurement transducer includes 1L circulation discharge and 0.5 L circulation discharge，selecting according to wanted discharge of fuel dispenser. Discharge adjustment Over a long period of operation the accuracy of measurement transducer declined due to either parts abrasion or large change in oil temperature and viscosity. Therefore, regulative device often used to adjust the accuracy within the stipulated scope of national metrology appraisal. The following procedure is conducted as measurement accuracy decline.

fuel dispenser is a POS functionality.　　The ticket re-print for an Outdoor self-service operation is not necessary.　　Brief Description　　The customer comes back to the cashier requesting a copy of the (POS) Eft receipt.　　The cashier verifies the customer right for the request and select the POS functionality.　　The receipt is printed (probably with some specific text on it) and given to the c fuel dispenser ustomer.　　Pre-Conditions　　The customer wants the reprint of the receipt (e.g. it was not readable for some reasons lost etc.).　　The merchant has the appropriate rights to accept payment card and the site systems are correctly set to　　perform the payment.　　The fuel dispenser EPS is enabled for transactions handling in a status openstand by for new transaction.　　The POS is open in a shift cashier operated.　　Actors　　Actor Description　　Cashier Person who enters items at the POS and is accountable for the money in the cash　　 drawer.　　Customer Person who brings the item(s) to the POS and who wishes to purchases it (them).　　POS The application (or device) that allows the Cashier to enter transactions into the　　 system.　　EPS The application that manages the card payment application.　　Main Flow Description　　1.

fuel dispenser the first 12 senators spoke for longer than the nominee. Patrick Leahy of Vermont waxed thespian on the subject of strip-searching young girls, a practice of which he said Mr Alito was too tolerant. In one burst, he rolled the words “strip-search�around his mouth four times and “ten-year-old girl�five times. Judge Alito, when he could get a word in edgeways, explained that in the fuel dispenser case in question, police officers asked a magistrate for permission to search everyone in a suspected drug dealer s house, since they had cause to believe he hid his wares on other people. The officers got a warrant that they thought authorised this, but which lawyers fuel dispenser subsequently argued didn t. The suspected dealer s wife and daughter were searched by a female officer. No drugs were found. The officers were sued. Judge Alito voted to dismiss the suit, arguing that the officers had reasonable grounds to think the search was warranted. Activists on the left say Judge Alito is a far-right ideologue. They gripe that Democratic senators were too soft on the last Bush pick to appear before them. John Roberts was confirmed as chief justice last year by 78 votes to 22, after a performance even his foes admit was brilliant. Judge Alito cannot match the polish of Chief Justice Roberts, who spent most of his His record on the career as an advocate before the Supreme Court, and is therefore practised at swaying bench is one of the powerful. Judge Alito seems shy and bookish—his wife, a former law librarian, says it cautious rulings and took him 13 months to ask her out. When he first appeared before the Senate, he was scrupulous so ner
