but also container, vacuum pump. The hose made according to GB10543 consists of inner rubber layer, enhancing layer, conductible metal line and exterior rubber layer. Whichever hose abided by the requirements of GB/T9081-2001 Fuel dispenser for vehicle and JJG443-98 Fuel Dispenser in terms of safety and accuracy. During operation pay much attention to protect hose: avoid as much crook as possible; prevent pressure on hose; avoid and reduce abrasion with ground. 4. Connection and seal about pipe fuel dispenser line and hydraulic elements Each part of fuel dispenser adopts pipeline connection, dividing into hard type and soft type. In hard type conn fuel dispenser ection steel pipe, brass pipe and aluminum pipe are adopted as pipeline, but in soft type one hose and corrugated pipe. Connected components includes relative elbow jointer, flange and directive jointer. There are following seal types: cone-shaped seal, subulate thread seal, O-ring seal, rubber and asbestos gasket, cork and rubber board, engineering rubber board. According to regulation stipulated in GB/T9081 every fuel dispenser should be conducted sealability testing before leaving factory, no leakage found under normal operation. As replace some parts or found leakage these problems should be paid attention: Cone-shaped seal structure Cone-shaped seal structure also called as expanding jointer, which is composed of pipe with outstretched end, flat spout and outside thread bushing. Sealability is ensured through tightly integration of subulate surfaces. In disassembling or reassembling cone-shaped seal structure pays much attention not to hurt or broken sublatae surfaces, cleaning waste. Thread airproof As disconnection or reassembly thread surface should be kept clean, daubing seal glue or seal belt before installation. O-ring seal Most manufacturers adopts national standard to design O-ri fuel dispenser ng seal, reaching a good sealability. However, some parts is impossible to adopt national standards because of specific structure. Thus, user should purchase or employ appropri

is polarised between “work-rich� and “work-poor�households, which particularly affects families. Jobless couples with children are more common than in many other advanced countries. More important, lone parents without jobs make up a bigger share of families. In 2000 they were 7.3% of all households with children, three times the average among 24 countries in the OECD (see chart). More recent British figures highlight how crucial joblessness is in determining child poverty. In 2004-05, lone p fuel dispenser arents without work were raising 13% of all children but 31% of poor children. Jobless couples were bringing up 6% of all children but 19% o fuel dispenser f poor children. Together, the two groups accounted for only a fifth of all children but a half of poor ones. What this suggests is that the priority should now be to get poor jobless parents back to work. The government has been trying to encourage this by providing extra financial support for working parents. Such help is now among the most generous for low-paid employees in the OECD. These financial incentives appear to be having some success. The lone-parent employment rate, for example, has risen quite sharply over the past five years. Steep increases in the minimum wage are making work more worthwhile, although there is increasing worry that they may also raise unemployment. What is crucial now, says Mr Whiteford, is for the state to exert more pressure on lone parents to work while continuing to help them with child care. Britain is unusual in not requiring single parents to look for jobs until their youngest child is 16. Australia, which also has a high proportion of lone parents who are not working, has a similar rule. In most other countries in the OECD, by contrast, single parents have to seek employment much sooner. In July, Australia will change its rule and make new l fuel dispenser one parents look for work once their youngest child is six. Such a reform will seem harsh to many of Labour s supporters. But the government has invested political
