COMPANY INTRODUCE

China Hongyang Group, is an integrated enterprise with the research & development, production and marketing of Fuel Dispenser and related accessories as well as service station concerning equipments. It concentrates on the relative manufacture & services of filling station such as Hongyang tax control Fuel dispenser, IC Card fuel dispenser, manage system of network for stations, submerge pump and liquid level devise. China Hongyang Group, designed supplier of SinoPec and PetrolChina, our HONGYANG products have been sold to over 50 countries in South-east Asia, Mid-east, Africa, Europe and well received in their markets.

This device often is installed on check valve, hose pipeline also release certain hydraulic pressure. Pipe Resonance Apart from hydraulic stock, other hydraulic components also cause a certain degree of noise in pipeline, such as vane pump, overflow valve, vapor separator, measurement transducer, solenoid valve and nozzle. Sometime pipe resonance will be generated if the inherent frequency of pipe equivalent to hydraulic pulse resulted from hydraulic components of fuel dispenser. At that time, the normal worki fuel dispenser ng state will be affected, which is harmful to staff’s health due to intensive noise. In order to explain this problem, the inherent frequency of pipe is introduced here. Pipe inherent frequency is: ω0 = kπ/2 l2 ·EJgGd+Gj (2-14) In the above formula: ω0 ── inherent frequency of pipe l ── supporting point distance E ── elastic modulus of pipe material J ── inertial moment of pipe section g── acceleration of gravity Gd── weight of pipe per meter Gj──liquid weight in per meter of pipe K── modifying coefficient K= 1-pA+mv/2π2EJA/l2 (2-15) In above fuel dispenser formula: A ──pipe section m ──liquid weight in per meter of pipe v ──velocity of flow of liquid in pipe Several relative parameters affect the inherent frequency of pipe in Formula 2-14. Therefore, most manufacturers pay much attention to these elements that affect pipe inherent frequency and pulse frequency of hydraulic components in the design and manufacture of fuel dispenser, making the two frequencies as much different as possible so fuel dispenser as to appear pipe resonance in fuel dispenser. 3. Hose used for fuel dispenser There are two kinds of hose used in fuel dispenser. one is made according to GB/T10543 Rubber Hose Used for Refueling and Discharge of Airplane, connected oil indicator with nozzle; the other kind of hose is used in fuel dispenser with vapor recovery device, not only connecting oil indicator with nozzle,

receives the physical address.　　For example consider the case of a site controller (PNA 21 LNA 21) that wants to configure　　a dispenser (PNA 11 LNA 11) to send its unsolicited messages to a tank gauge (PNA 91　　LNA 91). It cannot do this unless it knows the physical node address of the tank gauge since　　the Write Recipient Address Table command only contains a logical address field. Once a　　heartbeat command has been received from the tank gauge then its physical address can be　　obtained and adde fuel dispenser d to a Physical Address Table within the site controller.　　Note also that each subnetnode address must be unique within an IFSFLON network.　　FP2_1.83 IFSF STANDARD FORECOURT PROTOCOL October 2002　　 COMMUNICATION SPECIFICATION　　Page: 34　　4.5.2.1 Read Recipient Address Table　　 Message provided Request message on Answer message on Answer received by　　 by the application the Network the Network the originator　　 application　　 LNAR fuel dispenser LNAR LNAO　　 LNAO LNAR LNAR　　 IFSF_MC = 2 IFSF_MC = 2 IFSF_MC = 0 IFSF_MC = 0　　 BL BL　　 M_St M_St M_St M_St　　 = Read + token = Read + token = Answer + token = Answer + token　　 M_Lg = 3 M_Lg = 3 fuel dispenser M_Lg M_Lg　　 DB_Ad_Lg = 1 DB_Ad_Lg = 1 DB_Ad_Lg = 1 DB_Ad_Lg = 1　　 DB_Ad = 0 DB_Ad = 0 DB_Ad = 0 DB_Ad = 0　　 Data_Id = 3 Data_Id = 3 Data_Id = 3 Data_Id = 3　　 Data_Lg = 2 x

r about whom they will serve. They say they will plough more resources into vetting applications but, as Mr Youngblood points out, this would raise their costs. There is no easy way out. Moody s and other debt-raters have cast a worried eye over the market, placing subprime deals on watch for a possible downgrade. Regulators are also twitchy. They have stepped up warnings about slack lending standards. Nerves are also jangling in the capital markets. These days large numbers of housing loans are moved off fuel dispenser banks books, bundled together as so-called mortgage-backed securities (MBSs) and sold to investors. In theory, this helps the banks to reduce risk, makes money for intermediaries who trade the securities, and allows the investors to pick tranches of debt that match their risk appetite. Thanks to financial alchemy, an MBS made up of low-quality loans can still enjoy a good credit rating. If too many of the home loans backing the security are toxic, however, investors will feel pain. That is happening now. The ABX Home Equity 06-2 index, whose price reflects the market s view of bonds rated BBB-minus backed by subprime loans made earlier fuel dispenser this year, has fallen sharply since mid-November (see chart). Hedge funds and others have been using derivatives to short bonds backed by subprime mortgages. Dubious mortgages are now a growing share of the mortgage- backed market, so there is scope for more trouble. Of the $1.02 trillion of MBSs issued in the first half of this year, over 40% was linked to subprime loans, up from 6-8% in 2000-03, says CreditSights, a research boutique. I fuel dispenser n a sign of how important the MBS market has become to Wall Street s big securities firms, they are playing a lead role in consolidating the subprime business. Since the summer, Morgan Stanley, Merrill Lynch and Bear Stearns have all bought mortgage lenders; Lehman Brothers has acquired several in the past three years. The point of this “vertical integration�is to feed the banks securitisation desks,
