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

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

ABSTRACT
Metals and plastics waste materials create serious environmental problems, mainly owing to the inconsistency of the wastes streams. The purpose of this paper is to evaluate the possibility of using mixed iron filings and granulated plastic waste materials simultaneously to partially substitute the fine aggregate in concrete composites. Type I Portland cement was mixed with the aggregates to produce the concrete composites. Three weight fractions (30, 40, and 50%) of iron filings waste aggregate were used with 5% of ....etc

super elastic iron alloy maintains its original shape even after serious stretching,The iron alloy's stress level is about twice that of nickel titanium ,metal's super-elasticity allows it to return to its original form and gives it additional properties, such as ductility and a change in magnetization and it can be made into a very thin wire that can reach the inner part of the body like the brain to deliver stents , which are tubes placed in blood vessels to stop them from collapsing. Currently, heart stents are delivered into the body using ....etc

Abstract
The influence of the diesel particulate filter additives (DPA) SATACEN and EOLYS on biodiesel fuel quality has been evaluated. Both additives significantly affected the oxidation stability of neat biodiesel. The influence on acid values and CFPP was found to be only small. Combination of diesel additives with biodiesel additives like oxidation stability and CFPP improvers led to similar results. Results indicated that DPA also lowered the efficiency of the oxidation stability improver Baynox. Furthermore, the CFPP additives Chimec an ....etc

What is Pyrophoric Iron Oxidation?
The word pyrophoric is derived from the Greek for
fire-bearing. According to Webster's dictionary,
pyrophoric material means any material igniting
spontaneously or burning spontaneously in air when
rubbed, scratched, or struck, e.g. finely divided
metals. Iron sulfide is one such pyrophoric material
that oxidizes exothermically when exposed to air. It
is frequently found in solid iron sulfide ....etc
