imbedded and exported from concrete base, filling in pipes hole with sand in case of diffusion of vapor. Delivery pipe in concrete should be a little higher, connected with corrugated pipe through flange and oil-resistant gasket. (See Diagram 5-2) Installation of pipeline and tank 3.1 The set of design of tank and pipeline should be conducted by locale design agency that has acquired ratification of public safety and firefight department with qualified capacity. In order to ensure system safety, filling station should not self –design pipeline of delivery oil. Diagram 5-3 is a pipeline installation sketch map of fuel dispensers and hydraulic system, which is provided for reference. The design and construction of filling station should conduct in accordance with the relevant stipulation of national standard GB 50156-2002 The Design and construction regulations of vehicle LP-Gas Station. Diagram 5-2: Connection chart of inlet pipe and corrugated pipe 3.2 Pipeline between fuel dispensers and tank should be slant to tank. In hot whether pipeline slope regulated as 0.2% in GB50156 is easy to generate cavitation. Foreign fuel dispenser factories regulate larger slant such as Gilbarco 10ft (about 1.67%), Wayne 1:48 (2%). Thereby, it is suggested that the slant should be in scope of 1.5~~~ 2%.

Tank should not be burred in the earth in which includes coal residue or chemicals, and surrounded by non-erosive material such as sand or thin earth, thickness no less than 0.3m. 3.4 The level distance between fuel dispenser and tank should be 20m or more as long oil could be suck without any leakage. The vertical distance between the inlet of fuel dispense and the nadir of oil level should not exceed 4m. The diameter of pipe between fuel dispenser and tank is 38m (1 1/2’�, which keeps clean with few elbows. The connection of delivery pipes fuel dispenser

it, show that 74% of young people infected in sub-Saharan Africa are female. Biology is part of the problem. The skin lining the vaginal tract and, in particular, the cervix, contains immune- system cells that make their way to the surface in response to infection. These are cells of the type that HIV infects. But social mores are also culpable. In many cases, the virus is passed on by older men—who have had more time to become infected—taking teenagers as mistresses. A man who wants to protect himself can don a condom. To achieve the same end, a woman must persuade him to do so, and no amount of pleading can ensure that this happens. One proposed answer is vaginal microbicides. These are virus-killing gels and creams that a woman can use without male permission and, indeed, without the man necessarily knowing that they are there. Five such microbicides are in advanced-stage tests at the moment, but all suffer from the fact that they must be applied only an hour or two before sex, in order to minimise the chance that they will leak away. One improvement could be flexible rings that sit at the neck of the cervix and release microbicidal drugs for several weeks. But for convenience s sake, nothing would beat gels and creams that hang around for more than a few hours. Patrick Kiser, of the University of Utah, and his co fuel dispenser lleagues, believe they may have hit on the answer. Their solution, described in t fuel dispenser he Journal of Pharmaceutical Sciences, is more than a metaphorical analogy to the condom. They envisaged a microbicide-containing lining for the vaginal tract that is a squishy solid rather than a liquid. That would prevent it leaking out. But they also imagine that this instant condom would be clever enough to melt on cue, releasing anti-HIV drugs whenever it comes into contact with semen. The problem is that to get a solid microbicide to all the right places, it is easiest if it starts off runny. To find an appropriate material, Dr Kiser assembled a “library�of polymer mixtures and fuel dispenser
