ine bad effects of accuracy. 2. Pipeline noise Noise and tremble are not generated by pipe itself but hydraulic shock, pipe resonance and pressure pulse. Here explain, combining operation and maintenance of fuel dispense, these reason for noise and tremble 2.1 Hydraulic collision Hydraulic collision refers to the phenomenon in which oil pressure in pipeline is increased quickly as pipe switch open or close or liquid changing flow direc fuel dispenser tion. Hydraulic collision could lead to pipeline noise, which are result from piston changing direction of measurement transducer and witching on or off pipe valve. Δρ= 12lv11+EoE·dδ (v2=0,t≤T) (2-10) Δρ= 12lv11+EoE·dδ ·Tt (v2=0,t≤T) (2-11) Δρ= 12 fuel dispenser lv11+EoE·dδ ( partial v2�?,t≤T) (2-12) Δρ= 12lv11+EoE·dδ ·Tt (partial v2�?,t≤T) (2-13) In above formulae: Δρ── increasing pressure value; υ1── previous velocity of flow υ2── latter velocity of flow T ── time that start from collision to reflect T=2la T ── changing time of velocity of flow fromυtoυ2 E0 ── elastic volume of fluid cubage E ── elastic modulus of pipeline d ── inner diameter of pipe δ── pipe thickness l ── diffused distance of shock wave a ── diffused speed of shock wave The above formulae illustrate four kinds of stock pressure on pipe in corresponding operations in which switching on or off nozzle quickly or slowly. They also explain that slowly switch on and off nozzle generating less collision pressure than that of rapidly under a certain parameter of pipeline system of fuel dispenser. Similarly, it is applicable to stock noise. Therefore, user shall slowly turn on and off nozzle in operation so as to reduce hydraulic stock and noise, and prolong fuel life service of fuel dispenser. Most of manufacturers of fuel dispensers have mounted anti hydraulic stock device in hydraulic system in order to abate the effects to fuel dispensers. fuel dispenser

continuing protests. But if he holds firm, and the new contract turns out to be popular with employers, it might then be extended further up the labour market, with benefits all round. French students are right to fear insecurity, but not the sort that they are protesting about. The country s real shame—and the biggest contributor to last autumn s riots—is mass unemployment, which has been barely dented, by governments of left and righ fuel dispenser t alike, in two decades. One in ten workers is out of a job; one in four among young people; and one in two on the roughest estates. That is genuine insecurity. © 2006 .  About sponsorship Stock exchanges Coming together Mar fuel dispenser 16th 2006 From The Economist print edition The prospect of a transatlantic merger is long overdue THE would-be acquirer was founded in New York 35 years ago as the world s first all-electronic stockmarket. Its quarry is one of the oldest exchanges, tracing its history back to the coffee-houses of 17th-century London. NASDAQ, based in New York, and the London Stock Exchange (LSE), which last week became its target, are as different as bull and bear. But then pretty much every feasible exchange is caught up in the frenzied talk of consolidation just now. In the past 15 months the LSE has been pursued by a string of foreign suitors, from continental Europe and Australia. Deutsche Börse and Euronext, two big European exchanges that have eyed the LSE in the past, sound increasingly interested in merging with each other. The New York Stock Exchange (NYSE) may yet bid for the LSE or another exchange. Even Chicago s futures and options exchanges have become tangled in the speculation. One world These mergers are being seen as a step towards the creation of global financial exchanges, a glint in the eye of anyone for whom the existence of the national bourse is as quaint as the existence of the national airline.
