Abrasive Jet Machine

Introduction
Abrasive jet machining (AJM) is a non-traditional machining
process that can machine material without generating heat and
shock.
Abrasive jet machining (AJM) is commonly used for Cutting,
Cleaning, Drilling and Etching operation

Mechanism of AJM

Fine particles are accelerated in
gas stream .

The particles are directed towards
the focus of machining.

As the particle impacts the surface,
it causes a small fractu ....etc

Polyfuses is a new standard for circuit protection. It is re-settable by itself. Many manufactures also call it as Polyswitch or Multifuse. Polyfuses are not fuses but Polymeric Positive temperature Coefficient Thermistors (PPTC). We can use several circuit protection schemes in 'power supplies to provide protection against fault condition and the resultant and over temperature damage. Current can be accomplished by using resistors, fuses, switches, circuit breakers or positive temperature coefficient devices.Resistors are rarely an acceptable ....etc

Abrasive Jet Machining
INTRODUCTION
Abrasive water jet machine tools are suddenly being a hit in the market since they are quick to program and could make money on short runs. They are quick to set up, and offer quick turn-around on the machine. They complement existing tools used for either primary or secondary operations and could make parts quickly out of virtually out of any material. One of the major advantage is that they donot heat the material. All sorts of intricate shapes are easy to make. They turns to be a mon ....etc

A jet engine is a reaction engine that discharges a jet of rapid motion that generates thrust by jet propulsion. This broad definition includes air jet engines (turbojets, turbojets, jet jets, and jet jets) and airless jet engines (such as rocket engines). In general, jet engines are combustion engines.In common parlance, the term jet engine refers to an internal combustion air jet engine. These typically feature a turbine-driven rotary air compressor, with surplus energy providing thrust via a propellant nozzle - this process is known as th ....etc

POLYFUSE

INTRODUCTION
Current flow in a conductor always generates heat. Excess heat is damaging to electrical components. Overcurrent protection devices are used to protect conductors from excessive current flow. Thus protective devices are designed to keep the flow of current in a circuit at a safe level to prevent the circuit conductors from overheating.
A fuse is a one-time over-current protection device employing a fusible page link that ....etc

Abresive Jet Machine

It is a newly developed technology used in industrial countries. This is adopted for machining operations.

Features

In this machine a high velocity of abrasive stream is used for machining. The abrasive particle have a vibration of about 50 hertz is mixed with high pressure gas or air in the mixing chamber. Then the stream is emerges through a small nozzle mounted on a fixture to the work piece.

WiFi Enabled Wireless Operated Fire Extinguisher Vehicle with Water Jet Spray

In this paper, the authors extinguish fire using robot which is remotely controlled through wireless. The robot can move through any path whose motion is controlled through the Wi-Fi network using buttons interfaced by a software program. When the robot faces a fire then it is made to extinguish the fire with the help of pump motor connected to a water tank mounted on its body. PC works as a remote to control the motion of the robot either to move it forward or bac ....etc
