hydraulic section of fuel dispenser is a comprehensive presentation of the applied hydrodynamics, mechanical manufacturing, engineering mechanics, engineering material, automotive control principle and metrology. The performance of hydraulic components and matching ration is symbolic of fuel dispenser. This chapter mainly introduces the structure of hydraulic components, working principle and troubleshooting of fuel dispenser, such pump, oil-air separator, measurement transducer, nozzle, oil indicator and solenoid valve. Since there are many brands of fuel dispenser that mounted different hydraulic parts it is difficult to comprehensively introduce domestic fuel dispenser’s hydraulic components. In order to facilitate the reader to better understand hydraulic components and master maintenance technique, this handbook will present the popular fuel dispenser’s structure, working principle an fuel dispenser d reparation methods. Despite different model of components there are still many similarities in their working principle. To learn the common components is conducive to know other model. As a failure phenomenon occurred by various causation, only deeply understand products one can precisely judge its trouble. Therefore, we spend a whole chapter to introduce the working principle of components. In fuel dispenser market there are many hydraulic parts with similar appearance and inner structure. Different manufacturers with different research and understanding provide various products in terms of performance and failure presentation. Readers could maintain not only according to the User’s manual provided by manufacturer, but also analyze and repair to the knowledge introduced in this chapter. Professional maintenance operator assigned by manufacturer will be asked when meeting some much difficult trouble. The hydraulic source system of fuel dispenser composes of pump and motor. By delivery model it divides positive delivery and negative delivery. The former model adopts submersible pump, usually a centrifugal pump that fuel dispenser fuel dispenser

While many are focused on making extra money, many more say they will do it for the “mental stimulation and challenge� As the Conference Board, an American association of businessmen, put it last year “working in retirement, once considered an oxymoron, is the new reality� © 2006 . The ageing brain Wisdom or senility Feb 16th 2006 From The Economist print edition Understanding how the brain ages could help to slow deterioration AT WHAT point does an ageing mind become a liability and not an asset? The answer depends on what that mind is asked to do. If the task requires a wealth of knowledge and experience, then the elders have it. If the job needs sharp and fast thinking, youth triumphs. The inherent differences between people mean that a quick-witted 60-year-old can outperform a slow-minded 25-year-old in tasks at which youth shoul fuel dispenser d prevail. But, in general, from the age of 20, you can see a decline in a person s raw mental agility—recalling a list of objects, grouping objects into classes and replacing words with numbers (or vice versa). The speed of reaction slows, too. However, in the real world, the acquisition of knowledge will obscure the consequences of age- related decline. Performance in many jobs depends on how much you know and how well you know it, both of which increase well into your 60s. Knowledge tends to decline sharply after 65, but that may be the consequence of retirement rather than its cause. As the brain grows older, it undergoes complex and poorly understood changes—from the biochemical, to the molecular, structural and functional—that lead it to shrink. The brains of those aged 40 and older decrease in volume and weight by 5% every ten years. This shrinkage, though universal, affects people s mental performance in very different ways. Similarly, other changes in the brain—such as the gradual decrease in the supply of oxygen and sugar—leave some peoples memories unaffected, while others are s fuel dispenser fuel dispenser
