AUTOMATIC POWER TRANSMISSION SYSTEM
ABSTRACT
The automatic transmission system is very advanced system and particularly used in foreign cars. This system provides comfort to the driver and make the driving more flexible to suit the drivers need with road conditions. Also, electronically controlled automatic transmission system creates compactness to overall control panel. So that the driver has need to select only correct mode.
Before doing advancement in this particular system, there is more friction present which directly affects the fuel economy. But now a days, the automatic transmission with Transaxle and overdrive unit (particularly fitted at higher gear) gives better fuel economy as compared to the manual operated gear box.
INTRODUCTION
In USA, the first automatic transmission with a torque converter an epicyclic gearing was introduced in mid 1930 and in Europe in 1950 Simple automatic system is refined by many advance features. So that the sophistication control of system is possible and also comfort to driver. Safety for passanger is increased. All automatic transmission systems are controlled with reference to vehicle speed and engine load. Due to electronic control used in transmission of power from engine to road wheel though the torque converter and its system on additional features may introduced.
e.g.
1) Indication of engine temperature and ambient temperature.
2) Skid prevention on icy road.
3) Rate of change of acceleration
In earlier systems these data are obtained by mechanical, electrical and pneumatic sensors. But now a days these data can be obtained from electronic sensors. In automatic transmission system, the driver only needs to manually select the forward set of gears (D-range) or the reverse gear(R-range). The automation changing gear ratio relieve the driver of the responsibility of selecting the best possible ratio for each condition and make driving easier and more comfortable.

AIR CONDITIONING OF MULTIPLEXES
AIR CONDITIONING OF MULTIPLEXES
INTRODUCTION
The Indian consumer is today more knowledgeable and demanding. With higher disposal income and relatively improved standard of living, people are ready to spend time at their chosen leisure centers for entertainment. The young generation today, believes in working hard, earning well and spending lavishly on recreation. Having all entertainment facilities such as theatres, video game parlor, food court, restaurants, supermarket and bowling alley and discotheque under one roof is become common.
Occasionally, one would like to spend available time with their family out of their home and unwind themselves from their daily routines. Multiplex is a building which provides all above mentioned facilities under one roof. First fully air-conditioned multiplex in India was launched in Ahemedabad four years ago and another five or six multiplexes have sprouted in Ahemedabad alone. Throughout the country more than 100 multiplexes are under construction and 500 more at various stages of planning. One or two decades ago in India ‘Multiplex’ concept is totally new. Few big theatres, auditoriums also can’t do full air conditioning. They used various types of ventilations, fans, air cooler. But this system does not give efficient air conditioning and comfortable environment. Also air cooling system produce lots of noise.
