. Inlet pressure labeled as P1, annular passage labeled as P2 that is equivalent to the P1. Diagram 2-18 the working principal drawing of metal piston measurement transducer Diagram 2-18 a: piston 1 reaches the furthest point. The side window of cylinder 1 is entirely opened by piston 1. The oil in the centre oblong chamber flows into the top of piston 4, its pressure P1. At the same time, piston 3 reaches the nearest point, annular groove overlap with the side window of piston 3, making it connected with the elliptical outlet at the upper cylinder. (See diagram 2-17). Meanwhile, Piston 2 impels oil into annular passage and discharge out via the side window of Piston 3 and top elliptical window. In the status, piston 2 and piston 4 lie in cross-bencher position, covering the wi fuel dispenser ndows 2 and 4 respectively. Their top pressures are P1 and P2, P1 ＞P2. Owing to the different pressure, piston 2 leaves the center, but piston 4 reaches the center. So do piston 1 and piston 3.

or 28 years, thanks to a series of blatantly rigged polls. Now in opposition, it claims itself to be the victim of electoral fraud. In Guyanese politics, squabbles over electoral technicalities have long outweighed policy issues. After the 1997 elections, protests over irregularities boiled over into riots and massive public- sector strikes. This year, a row over electoral lists has split the Elections Commission. And the general election, due under the constitution to be held by August 4th, has had to be postponed until later in the year, because of further technical hitches. But until last week s killings, the electoral climate had seemed less fraught than usual. A shift in the ethnic balance may bring the opposition a few extra seats, so it has greater reason to mak fuel dispenser e elections work this time. Indeed, the pre-poll skirmishing had begun to look like a ritual dance rather than anything more sinister. An earlier series of high-profile crimes had raised tensions, but they have proved difficult to decode. In January, Ronald Waddell, a black television talk-show host and fierce critic of the government, was shot dead. His show had been dropped three months earlier, after he described black gangs in the country s main crime hotspot as the “Buxton resistance� who were defending “the African nation in Guyana� But he was not widely popular, and neith fuel dispenser er party seemed to gain from his death. In February, gunmen killed eight people in the predominantly black village of Agricola, south of Georgetown—again for no obvious reason. Two of the guns fired were later u fuel dispenser sed to kill Mr Sawh and his family. Politically motivated criminal gangs with links to the drug trade are the most likely assassins. Guyana s thinly populated interior is a staging post for Colombian cocaine. America s annual narcotics report, published last month, suggests that drug money represents as much as a fifth of Guyana s economy. The PNC-R and PPP-C are old enemies, but neither wants to see anarchy. The two parti
