Magnetic refrigeration

Refrigeration is the process of removing heat from an enclosed space or from a substance and transferring it to a place where it is unobjectionable. Magnetic refrigeration, based on the magneto caloric effect (MCE), has recently received increased attention as an alternative to the well-established vapor compression refrigerators for room-temperature applications. Conventional refrigeration systems are causing a great threat to the nature. We all are aware of the impact of refrigerants such as cfcs, hfcs, etc. but we still continue to use it. Why? It is mainly because of the non-availability of an alternative technology that is cost efficient.

Incineration Plants

A waste treatment technology, which includes the combustion of waste for recovering energy, is called as “incineration”. Incineration coupled with high temperature waste treatments are recognized as thermal treatments. During the process of incineration, the waste material that is treated is converted in to IBM, gases, particles and heat. These products are later used for generation of electricity. The gases, flue gases are first treated for eradication of pollutants before going in to atmosphere.

Mechanical Heat Pump

Objective of this paper presentation is to study the performance characteristics of Hilton Mechanical Heat Pump. Experimental set up is mounted on a single platform. The Hilton Heat Pump is designed solely for educational purpose and data in qualitative form can be obtained for analysis of the heat pump. It consists of

Autocollimator

Autocollimators are used to detect small misalignments. If a parallel beam of light is projected from the collimating lens and if a plane reflector R is set up normal to the direction of the beam, light will be reflected back along the same path and light will be brought back to focus exactly at the position of the light source

Brakes And Pneumatics

Type of Brakes
  • Service Brake: Electric Regenerative brake and Electro-Pneumatic (EP) friction brake blending, Load weighed and Jerk Controlled
  • Emergency Brake: EP friction brake, Load weighed
  • Parking Brake: Spring applied, air-release parking brake
  • Holding Brake: EP friction brake
  • BP (Brake pipe)-back up brake: Pneumatic friction brake

Vacuum Brakes

A moving train contains energy, known as kinetic energy, which needs to be removed from the train in order to cause it to stop. The simplest way of doing this is to convert the energy into heat. The conversion is usually done by applying a contact material to the rotating wheels or to discs attached to the axles. The material creates friction and converts the kinetic energy into heat. The wheels slow down and eventually the train stops. The material used for braking is normally in the form of a block or pad. The vast majority of the world's trains are equipped with braking systems which use compressed air as the force used to push blocks on to wheels or pads on to discs. These systems are known as "air brakes" or "pneumatic brakes". The compressed air is transmitted along the train through a "brake pipe". Changing the level of air pressure in the pipe causes a change in the state of the brake on each vehicle.  It can apply the brake, release it or hold it "on" after a partial application. The system is in widespread use throughout the world.

Hexapod Robots

This paper emphasis the need for developing the legged robots rather than wheeled robots. Among these legged robots mentioned in this paper, we will particularly study about the cockroach-like hexapod robot and it’s importance. Over the undulated surfaces, robot movement with wheels becomes difficult. For working and exploring in unknown and rough terrain the use of legged robots is advantageous because their movement is less constrained by the shape of the surface on which they have to travel. The anti-personnel mines of over 100 million is injuring or killing more than 2000 people a month. Under this ultimate environment, a walking robot may be an effective and efficient means of detecting and removing mines while ensuring the safety of local residents and people engaged in the removal work. Hence, insect movement with legs is considered most stable. The present paper proposes an improved six-legged walking robot.

Fabrication And Performance Evaluation Of the Solar Still

Energy is the basic input required to sustain economic growth and to provide basic amenities of life to the entire population of a country. Energy can be an effective weapon in the battle against abject poverty in the country like India. Like other developing countries, India is also in the process of planning and development as such needs a quantum of energy for its development plans. It is the level and pattern of utilization of energy from different sources in any country, which is an index of industrial development and standard of living. Basically energy is utilized in four key sectors of our economy namely Agriculture, industry, commercial and the households. Due to increasing gap between demand and supply of energy there is an urgent need to utilize the different forms of non-conventional energy sources such as solar, wind, biomass etc. Among these energy sources one of the most important sources is solar energy.

Rapid Prototyping

Machining is a subtractive process, beginning with a solid piece of stock. The machinist must carefully remove material until the desired geometry is achieved. For complex part geometries, this is an exhaustive, time consuming, and expensive process. Some parts are even too complex to be machined. Rapid Prototyping is a method in which the part is created by a layer-additive process. Using a specialized software, a 3-D CAD model is cut into very thin layers or cross-sections. Then, depending on the specific method used, the RP machine constructs the part layer by layer until a solid replica of the CAD model is generated. Material selection is also method specific. The advantages of this process is clear: development of physical models can be accomplished in significantly less time as compared to the machining process. Some other applications of these technologies include development of models and tooling. Additionally, in the medical field, the convergence of medical imaging, CAD, and RP has made it possible to quickly develop medical models.

Open Architecture Made Easy With CIM

In this paper working of Quasi-turbines is discussed. It is a rotary combustion engine generating rotary motion through the combustion of the fuel, unlike the piston which convert reciprocating motion. These devices directly generate the rotary motion avoiding sine wave crank shaft conversion. This paper reveals a high efficiency, low emissions combustion process called Photo Detonation which is superior to thermal ignition process like Spark Ignition, Compression Ignition ,Homogeneous Charge Compression Ignition.
