motor and solenoid valve, with larger power. it also have the type of double-nozzle fuel dispenser mounted with total two sets of system, however, most manufacturers don’t install this type in order to reduce cost. With more than four nozzles, this fuel dispenser is able to be regarded as multi-nozzle type. At recent, most of multi-nozzle fuel dispensers made by domestic manufacturers are rebuilt from double fuel dispenser, which actually mounted two pieces of double fuel dispensers to one frame, in the same way 3 piece to six-nozzle. Therefore, learning the structure of double fuel dispenser is able to know multi-nozzle type. Here main introduce the double-nozzle fuel dispenser. Measuring main board is the core in fuel dispenser’s electric control system, which is reason why some people called this kind as ‘computer fuel dispenser� These operation including starting or stop, calculation, count, data generation and dialogue with machine also are conducted under the control of measuring main board. Display screen, keyboard and fuel dispenser’s switch are the main interface between operator and machine. The staff’s control command to fuel dispenser is mainly conducted through keyboard and nozzle switch, but report information and data are showed in display screen. The function of flow pulse converter, widely called as sensor, is to convert influx into electric pulse so that measuring main board process data. Motor is momentum of rotation of pump; solenoid valv fuel dispenser e used for presetting filling; power supply board is resource of electric system, which is used for converting alternative current into stable and clean directive current fuel dispenser needed. 2.

n be found using keyword searches. In addition, speaker-identification software will allow users (via computer microphones) to search the internet for audio clips recorded in their own voices, or those of other speakers. These are stunningly ambitious goals, and some of the audio features may not be ready by the time Quaero is launched. Yet they show that Quaero is intended to be far more than just another would-be Google, but a leap forward in search-engine technology. “Google is so hegemonic that no one even wonders about other interfaces,� says François Bourdoncle, the chief executive of Exalead, a French search engine that has taken on the task of integrating these various technologies under the Quaero umbrella. Even so, the most striking difference between Quaero and Google is not technological, but ideological. Quaero is a classic example of European state-funded industrial policy, while Google is the very embodiment of American free- market techno-capitalism. The use of government funds to back Quaero has raised eyebrows, even among its supporters, who worry that it might fall foul of rules that prevent governments from using state aid to give favoured firms an unfair competitive advantage. But so far no formal complaints against Quaero have materialised. The project is a public-private partnership, and the private firms involved are also committing considerable sums to it. The government funds, meanwhile, are being carefully distributed via fuel dispenser a complex system of favourable loans, interest-free cash advances, forgivable loans and grants for pre-competitive research, all of which are allowed under international trade rules. The project is further protected by the fact that big public-research organisations, including France s National Centre for Scientific Research and Germa fuel dispenser ny s RWTH-Aachen University, are also involved. When Angela Merkel took over as German chancellor in November, there were rumblings that she might not match Mr Schröder s commitment to the project. In fac fuel dispenser
