on quickly increase in recent year, consumption of finished oil increase al well, the vapor pollution and resource waste in forecourt become more important safety factor in considerable filing station, safety distance and vapor density in particular. At present, vapor separator device is installed and obtain content effect in most of large and middle cities reference to foreign improving measures. Its recovery principle is divided as two phases: first phase refers to closed discharge from tank vehicle; second phase refers to vapor recovery as refueling oil. Phase I vapor-recovery system The first phase system aims at to rebuild the delivery pipe and vapor recovery pipe between vehicle tank and tank. (Diagram 4-1) The volume of vapor will be increased as flowing into tank because of waves and shock. Th fuel dispenser erefore, the inlet pipe should be deeply stretched under oil l fuel dispenser evel so as to reduce oil waves. As for a tank exceeding 945L of volume, inlet pipe is needed stretching into oil no higher 15cm than bottom of tank. Oil flows into tank from under level, vapor flow back into vehicle tank under pressure. In principle, the volume of oil and vapor is corrective. In order to make as little as vapor volatize during delivery, the structure of traditional ventilating pipe should be improved, making system in sealed state under normal pressure range. Reclaimed vapor is dealt with through condensation, adsorption and burn after taking back. Its operation principle is similar to the vapor system of balanced nozzle. Diagram 4-1: Phase I Vapor Recovery System The pipeline installation is illustrating in Diagram 4-2. The height of air pipe at least 4m. The length of back air is shorter than air pipe, diameter larger than that of air pipe. It is prohibited to appear overflow phenomenon as vehicle tank discharge, shut off switch of air pipe. The jointer between air back and discharge pipe should adopt speed jointer. Phase II vapor-recovery s fuel dispenser ystem Phase II refers to the progress in which vapor in vehicle tank is

ing envelopes�based on tensegrity structures. Lightweight skeletal frameworks, composed of rods and wires and controlled by pneumatic “muscles� serve as the walls of a building; adjusting their configuration changes the building s shape. Mr Sterk is also developing the “brain�needed to control such a building based on information from internal and external sensors. Anders Nereim, chairman of the department of architecture and designed objects at the School of the Art Institute of Chicago, is not convinced that a central brain is the best way to control a responsive building, however. He suggests that the building should instead resemble a decentralised ecological system and should be made up of many independent sensors and actuators. Some of his prototypes include shadow- seeking lights that m fuel dispenser ove around, and curtains made of flexible solar panels that us fuel dispenser e the energy they collect to open and close themselves. “Distributed systems can recover from damage,�says Mr Nereim. Cars are already capable of monitoring their own performance and acting with a certain degree of autonomy, from cruise-control systems to airbag sensors. Such responsive behaviour is considered normal for a car; architects argue that the same sort of ideas should be incorporated into buildings, too. And just as the performance of a car can be simulated in advance to choose the best design for a range of driving conditions, the same should be done for buildings, argues Gian Carlo Magnoli, an architect and the co-director of the Kinetic Design Group at the Massachusetts Institute of Technology. He is devising blueprints for responsive houses. “We need to evolve designs for the best performing responsive-building models,�he says. So will we end up with cities of skyscrapers that wave in the breeze? It sounds crazy. But, says Mr Sterk, many ideas that were once considered crazy are now commonplace. “Electricity was a batty idea, but now it s univer fuel dispenser sal,�he says. The same was true of suspension bridg
