Here is a simple but inexpensive inverter for using a small soldering iron (25W, 35W, etc) in the absence of mains supply. It uses eight transistors and a few resistors and capacitors. Transistors T1 and T2 (each BC547) form an astable multivibrator that produces 50Hz signal. The complementary outputs from the collectors of transistors T1 and T2 are fed to pnp Darlington driver stages formed by transistor. dwivedi pairs T3-T5 and T4-T6 (utilising BC558 and BD140). The outputs from the drivers are fed to transistors T7 and T8 (each 2N3055) conn ....etc

Abstract
Security is something that is needed for every person irrespective of their post and working. Advancement in technology has made possible to impart security at every need. The line-man working either in an electrical station or on the area lines are exposed to heavy voltages and current environment. A small mistake may lead to a huge disaster. Hence, it is necessary to include full-proof security and safety control mechanisms. The main motive behind the project is to improve the old mechanical control system use ....etc

WHAT IS IT..????
It is a graphical plot between the different temperatures, Carbon content and phases of iron.
It is known as equilibrium diagram because the state of the system remains constant over a period of time
To produce the diagram or the graphical plot a series of cooling and heating curves of Iron with varying Carbon content was obtained.
Then the critical points of the cooling and heating curve were plotted on a temperature vs C content plot and thus the Iron carb ....etc
