FUEL DISPENSER & SPARE PARTS

FUEL DISPENSER & SPARE PARTS

Fuel dispenser are used in petroleum-retail service stations for filling lightweight oil including gasoline or diesel etc. We have taken up the production of fuel dispenser since1992. Among our gigantic business portfolio, oil transfer pumps were first put on our agenda and then mechanical fuel dispensers, electronic fuel dispenser in subsequence.

Our fuel dispensers have 3 series, namely, C series, D series and S series. All of the series share the same electronic system, which consists of flow meter, combination pump, auto nozzle etc. But C series is little in size and has a general outline with hoses from the middle. And D series contains jambs with stainless steel and hoses from the top. Then S series have a novel streamline outline and hoses from the top, which is bigger in size in comparison with the other ones.

IC card, according to principle of desktop, also needs a set of operating system as platform, that is, COS (Chip Operating System). From fuel dispenser the view of its position in intellectual card, it is much more like past DOC in personal computer. COS as core of intellectual card technology, all commands from exterior should be processed in operating system. This system is developed along with integrated circuit card from EEPROM to intellectual card with microprocessor. Compared with general operating system, operating system in card has many traits: address system security; COS is not a universal operating system because it is developed by various manufacturers. Yet, different commercial COS should be designed and developed in line with a basic and general international standard so that make sure the openness of system. Because of adopting unified interface in one factory, different chips may also provide same interface with similar functions. Safety threat and solution to IC card system The security of COS safety protection has integrated many current and matured safety technologies, its reliability lie in the following 3 items: fuel dispenser Secrecy: adopt encryption to deal information, preventing illegal store and withdrawal data. Integrality: hinder illegal alteration of information including fuel dispenser modification, deletion and increase, etc. Authenticity: system has ability to verify the sender and receiver of data, ensuring data valid and authentic. IC card applied system may be attacked during working. Some are by malice, others unconscious. The concrete attack methods are divided into 3 categories: Method I: Fake card, including fabricated card, changing card in operation, etc. Method II: compromised card, employing lost card or larcenous card to conduct operat

the late-1990s polls show that more people now think the monarchy will be around in ten years time. Yet attendance at Church of England services has continued to decline. Why is the queen prospering while the Church (outside its cathedrals and evangelical movement) languishes? One reason is that the monarchy thrives on indifference, while the Church is hurt by it. That might sound odd, fuel dispenser given that evidence of interest in the royal family is everywhere over a million people turned out in London for the queen s golden jubilee; dreary books about royals easily outsell ones about elected politicians; and the young royal princes fill the newspapers. But this fascination does not run very deep. According to one poll, only 10% of people aged between 16 and 24 think the monarchy is important to their lives. And what do you do, Ma am? But because the royal family is the monopoly provider of a something trivial, it hardly seems worth opposing. The Church, by contrast, offers a vital service to its 1.7m members—spiritual succour—and operates in a competitive confessional market where dissatisfied Christians can shop around. Indifference is thus a threat. A second reason is that the queen s avoidance of controversy (she never expresses political views) and of the press has reinforced the institution she fuel dispenser embodies. She never gives interviews, modelling her media strategy on that of her mother, who gave an interview in 1923 but apparently did not enjoy the expe fuel dispenser rience and kept quiet for the rest of her life. (This was probably wise Cecil Beaton s diaries describe her as “a marshmallow made on a welding machine�) One executive of a tabloid newspaper argues that this has enhanced the queen s mystique, comparing her with other celebrities who risk irritating their audience through over-exposure. The Church, on the other hand, cannot avoid damaging controversies even when it wants to, as the divisive row over ordaining
