Mileage Enhancement Silencer

The innovation is a modification in silencer of the two wheelers where part of the exhaust gas is used to pre-heat the air and charge leading to increased combustion efficiency of the engine. It results in the increase in the mileage by 25 to 30 per cent.
The system is mainly a heat exchanger consisting of exhaust line, a nozzle for exhaust gas, heat exchanging chamber (between intake air and exhaust gas), modified air intake line passing through the heat exchanging chamber, ,an additional chamber, and aluminum covers.
The exhaust gas enters the heat exchanger through the nozzle attached to the main exhaust line and supplies the exhaust gases from the same pipe to the heat exchanging chamber.
One end of the modified intake air line is kept between the engine fins so that it gets fresh air easily and the other end of the pipes is connected with the filter. This line is made of copper.
The additional chamber is situated behind the main chamber is connected with smoke outlet nozzle on the other side. Its purpose is to reduce the noise level. The aluminium covers are provided at both the sides of main chamber and make the device cool from the outside.
In this system the intake air is passed over the exhaust manifold (silencer), which results pre heating of the intake air. NIF facilitated its testing at BIT Mesra, Ranchi. The test report mentions that the use of the modified silencer and the system for preheating of intake air increases the mileage by 25 to 30 per cent. This technology is still in the process of being refined so that it can be used at a wide scale.
The following specification describes the nature of this innovation which is to be performed.

Fire Alarm "Thermostate Based"

Fire alarm

An automatic fire alarm system is designed to detect the unwanted presence of fire by monitoring environmental changes associated with combustion. In general, a fire alarm system is either classified as automatic, manually activated, or both. Automatic fire alarm systems can be used to notify people to evacuate in the event of a fire or other emergency, to summon emergency services, and to prepare the structure and associated systems to control the spread of fire and smoke.

 

Design

After the fire protection goals are established - usually by referencing the minimum levels of protection mandated by the appropriate model building code, insurance agencies, and other authorities - the fire alarm designer undertakes to detail specific components, arrangements, and interfaces necessary to accomplish these goals. Equipment specifically manufactured for these purposes are selected and standardised installation

methods are anticipated during the design.

Working

Fire alarm control panel: This component, the hub of the system, monitors inputs and system integrity, controls outputs and relays information. Primary Power supply: Commonly the non-switched 120 or 240 Volt Alternating Current source supplied from a commercial power utility. In non-residential applications, a branch circuit is dedicated to the fire alarm system and its constituents. "Dedicated branch circuits" should not be confused with "Individual branch circuits" which supply energy to a single appliance. Secondary (backup) Power supplies: This component, commonly consisting of sealed lead-acid storage batteries or other emergency sources including generators, is used to supply energy in the event of a primary power failure. Initiating Devices: This component acts as input to the fire alarm control unit and are either manually or automatically activated. Notification appliances: This component uses energy supplied from the fire alarm system or other stored energy source, to inform the proximate persons of the need to take action, usually to evacuate. Building Safety Interfaces: This interface allows the fire alarm system to control aspects of the built environment and to prepare the building for fire and to control the spread of smoke fumes and fire by influencing air movement, lighting, process control, human transport and exit.

Using martial 

Starter

When you turn on a fluorescent tube, the starter is a closed switch. The filaments at the ends of the tube are heated by electricity, and they create a cloud of electrons inside the tube. The fluorescent starter is a time-delay switch that opens after a second or two. When it opens, the voltage across the tube allows a stream of electrons to flow across the tube and ionise the mercury vapour. In this 'Model the stater is using for switching the main CKT, or to sense the change in Temperature (As a Thermostat)'.

Switch

In electronics, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another. The most familiar form of switch is a manually operated electromechanical device with one or more sets of electrical contacts. Each set of contacts can be in one of two states: either 'closed' meaning the contacts are touching and electricity can flow between them, or 'open', meaning the contacts are separated and nonconducting.In this Model 'Switch is using for activation or deactivation of model'.

"Electric bell

systems consist of the bell, a battery which furnishes the, An electric bell is sounded by the striking of a clapper actuated by a Hammer" In this Model 'Bell is main indicator For warning of fair'.

Board and Wire

Board is a base of installation all  integral material it should be made of soft top with side cover of wooden stripe's  for the fire alarm we can go with any of the size like 8x12 or 12x18 and also paint or decorate it as per your own imagination. Wire is wising for transmitting power/ electricity we can use the gauge as per load of indicator's or attached resistance.
