Chapter III Electric control system of fuel dispenser Article I Main functions of electric control system for fuel dispenser Fuel dispenser is operated under electric control, realizing refueling process. Its main function brief as followed: calculation of volume and sales: measuring CPU collect flow data from pulse sensor, and count volume and sales according to certain calculating method. Finally these data display on screen. Pulse sensor inspection: lock fuel dispenser as sensor occur trouble. Starting motor, stop control, switch on and off solenoid valve. Display function: show various filling information on screen Dialogue function: filing staff realize general operation through keyboard, display screen and nozzle switch. Network communication function: all fuel dispenses in network are managed and controlled by centre-control computer. Article II Electric control system configuration of fuel dispenser 1.

pe of those who, for the past 15 years, have been searching for ways of triggering that metabolic adaptation by means other than semi-starvation. The search for a drug that will stave off old age is itself as old as the hills—as is the wishful thinking of the suckers who finance such efforts. Those who hope to find it by mimicking the effect of calorie restriction are not, however, comple fuel dispenser te snake-oil salesmen, for there is known to be a family of enzymes called sirtuins, which act both as sensors of nutrient availability and as regulators of metabolic rate. These might provide the necessary biochemical link between starving and living longer. An elixir of life? Boosting the activity of sirtuins in yeast, nematode worms and fruitflies (three rapidly reproducing stalwarts of biological laboratories) does indeed result in longer lifespans. In 2003 a team led by David Sinclair of Harvard Medical School described 19 plant-derived molecules that activate sirtuins in yeast. One of these molecules, resveratrol, is found in red wine—which created excitement among those who think that a wine-rich diet is part of the explanation for the healthy old age apparently enjoyed by many who live in southern Europe. In February, a group led by Dario Valenzano of the Scuola Normale Superiore in Pisa, Italy, showed that the effect applies in vertebrates, too. Dr Valenzano s experiments with resveratrol increased the maximum lifespan of a small fish, called Nothobranchius furzeri, by 60%. (Nothobranchius furzeri was chosen because it is the fuel dispenser shortest-lived v fuel dispenser ertebrate known, with a normal maximum lifespan of 12 weeks.) Resveratrol, however, is only a starting point. Sirtris Pharmaceuticals, a firm based in Cambridge, Massachusetts, of which Dr Sinclair is a co-founder, has identified a number of synthetic molecules whose effect on yeast is many times more potent than resveratrol s. Although there is, as yet, no published evidence that sirtuins extend life in mammals, or that resveratrol activates
