scharge, turn anticlockwise to increase discharge; reassemble hand wheel pin and lead-seal it after adjustment. Common failure and Troubleshooting The main failure of four-piston measurement transducer includes outside leakage and accuracy decline. As appear outside leakage, all seal sections should be inspected. Generally, failure will be solved through fuel dispenser removing damaged or aging sealed components. Diagram 2-22: working principle of four-piston measurement transducer Through long time of operation, the accuracy of measurement transducer is declined due to various abrasion occurred on cam, ideal wheel, distributing valve, valve seat, and piston. From start, regulating adjusting wheel makes the accuracy meet the requirements about national metrology appraisal. If still can’t reach the wanted accuracy, some fuel dispenser abrasion examina fuel dispenser tions should be conducted, including components of piston, distributing valve and valve seat. These components surfaces are fragile to be scratched by hard grain, increasing inner leakage and accuracy decline. If appear above situation, replace piston or grind the surfaces of distributing valve and valve seat. Double soft piston measurement transducer The article will introduce the structure, working principle and maintenance. Structure This type of measurement transducer has two soft pistons, smaller than four-piston type. Appearance and partial cutaway view is illustrated in Diagram 2-23, structure and key components in Diagram 2-24. Diagram 2-23: Cutaway view and figure of four-piston measurement transducer It has two pistons formed a 120 degree angle, driven by connecting rod that force crankshaft moving. Component cylinder is installed in parallel. The two rolling bearings respectively installed on connecting rod and crankshaft reduces the friction. The end of connecting rod contacts with bushing. The oil discharge is controlled by distributing valve that communicating with inlet and outlet. On the top of distributing valve mounted a bearing used for installing cranks

fe messengers to the mix. This stimulates the formation of what are known as RISC complexes, which carry part of the double-stranded RNA around as a way of attacking reference, and destroy any RNA that matches it. infection The rea fuel dispenser son, from the cell s point of view, for doing this, is that healthy animal and plant cells never make double-stranded RNA. On the other hand, many viruses do. Recognising and destroying double-stranded RNA is thus a safe way of attacking infection. Whether that insight can be turned into drugs remains to be seen. But many are trying, and billions of dollars rest on their success. Roger Kornberg, the winner of the chemistry prize, and another member of fuel dispenser the faculty of S fuel dispenser tanford University, studied the process by which genes are copied into RNA in the first place. This is done by an enzyme called RNA polymerase, which binds to the DNA and runs along one of the strands of the double helix. Each time it comes to a new chemical letter on the strand it is reading, it reconfigures itself to add a complementary letter to the RNA molecule it is creating. Dr Kornberg worked out the details by crystallising the complex of DNA, RNA and polymerase at various stages of the process. He then photographed each version of the complex with X-rays. That process of X-ray crystallography, which calls for a lot of complex mathematics rather than the mere creation of a photographic image, was invented by two Britons, Sir William Bragg and his son Lawrence. They jointly won the Nobel prize for physics in 1915. Coincidentally, Dr Kornberg s father, Arthur, is also a Nobel laureate. He won the physiology prize in 1959 for working out the details of how DNA is synthesised. Whether such familial talent is a matter of nature or nurture will, no doubt, be the subject of a future prize. © 2006 .
