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 distributing 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 create 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 in fuel dispenser flow 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 fuel dispenser 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.

ns (read write instructions and　　 commands) from another controller device. It is envisaged that most inter-controller device communications will use the　　 TCPIP protocol (See IFSF document Communications over TCP-IP Part II.2)　　 Please note that a CD evaluates the write messages from left to right (as defined in the IFSF STANDARD FORECOURT　　 PROTOCOL PART II.1) and verifyvalidate all the data fields up to the first command field (included). All the data and　　 command fields after the first command field will be rejected either with 1 - Invalid value (too big too small not　　 accepted) or 6 - Command not accepted . In case no validationconsistency error is detected within the first part (up to the　　 first command field) than the first command will be executed. Meaning also if any data field preceding the first command　　 fuel dispenser is rejected (Data Acknowledge Status = 1 3 5 or 6) the command will not be executed but however the valid data　　 elements will be stored in the database.　　1.3 System Architecture　　 The CD is a controlling device fo fuel dispenser r forecourt devices. There can be one or more controlling devices on a forecourt. This　　 specification is not complete; it describes the common manufacturer and error code elements as used in all other IFSF　　 devices. As time progresses this specification will be developed further by adding additional databases and attributes.　　 The CD is an IFSF logical device. The CD application can therefore be partitioned to a variety of architecture modules. In　　 particular it can be partitioned to run on the same architecture module as other CD applications. There are two basic types　　 of architecture that are shown in Figures 1 and 2 below. The first is a multi-controller and the fuel dispenser second is where one CD acts　　 as a master. In the second architecture it is possible that the slave c

ssing education. But he has some sensible ideas. Subsidies for those who cannot afford to go to college are currently too complex; he would replace the five main schemes with a single $3,000-a-year tax credit. Teachers should be paid for performance, not just credentials. And schoolchildren should take shorter holidays. (The Democratic Leadership Council, a moderate Clintonian body, made the same proposal last month.) Americans are not saving enough for retirement. Well, some are. Mr Emanuel, after six years as a White House aide, earned $16m in two and a half years as an investment banker. For those who lack his quick wits and fat Rolodex, however, he proposes other ways to build up wealth. Employees should automatically be enrolled in 401(K) pension schemes unless they object. The middle class should be exempt from capital-gains tax. And families with an income of less than $100,000 a year should sur fuel dispenser render no more than 10% of it to the taxman. As a congressman, Mr Emanuel has proved himself something of a tax wonk, co-sponsoring a plan to do to the tax code s complexities what he once fantasised about doing to his political enemies. Perh fuel dispenser aps the most arresting part of the Plan concerns national security, the Democrats perennial weak spot. Again echoing Senator Clinton, he wants 100,000 more soldiers for America s overstretched army. He also wants an elite agency to fight domestic terrorism, like Britain s MI5. Of George Bush s Department of Homeland Security, he scoffs �It has 180,000 employees. The London bombings in July 2005 were the work of four men with backpacks. Whose organisation chart would you rather have?�Most radically, he wants all Americans aged 18-25 to undergo three months of compulsory disaster-training. Oh come, come, Emanuel Wouldn t it be more efficient to hire more professionals—paramedics, firemen and so forth? fuel dispenser Not in Mr Emanuel s view. He does not want merely to prepare for future disasters; he thinks his “universal citizen service�will bri
