Title: FSW Using Drilling Machine Authors: BEN AUSTIN B ALAPATT Abstract: Aluminium welding is done by Tungsten Inert Gas(TIG) welding, which is very costly. Friction stir welding is an economically better alternative for this. We have successfully done friction stir welding using the drilling machine on aluminium alloy. We have performed welding on 15 specimens and the tool never failed. We got satisfactory results in tensile tests, hardness tests, ultrasonic tests and liquid penetrant test. It was found that weld quality increased with increasing RPM and decreasing tool travel speed. We got better weld quality at 800 RPM and 50 mm/min travel speed. The tool travel speed can be further increased by increasing the RPM.

Title: REFRIGERATOR CUM AIR CONDITIONER Authors: OS, Sandeep; TM, Vishnu; PETER, SANJU; DAVIS, SEBIN K; S, SREENIVASAN Abstract: Refrigerator cum Air conditioner is the combination of two units i.e. domestic Refrigerator and Air-Conditioner. Our aim is to develop a device that performs both task at same time i.e. cooling refrigeration cabin and room. By this method the energy and cost can be reduced from the cost of individual equipment. In minimum construction, maintenance and running cost, this attempt is quite useful for domestic purpose thus those who cannot afford an Air Conditioner can have the comfort of Air Conditioner. Refrigerator has become a necessity of all households in 21st Century. In all metropolitan cities, environment degradation due to automobile & other factors is on the rise, therefore the requirement of air-conditioner has already been felt. The motivation for the project comes from rising energy demands and hence its cost. As we all know that we are lacking of power resources, so this project will help us in tackling this problem as we are trying to make a personalized cooling system which will run at a very low cost that can be afforded by a common man. Another objective of this project is to improve the utilization of waste heat from a domestic refrigerator. The continual operation of this equipment accounts more electrical energy consumption. Furthermore, a significant amount of waste heat is rejected by the condenser of refrigerator. The heat rejected by condenser is of low quality, meaning temperature is low. Thus, practical uses of waste heat from the domestic refrigerators are typically limited to space heating and water heating.

Title: SEMI AUTOMATIC AGRICULUTRAL POST HOLE DIGGER Authors: ARUN, P DAS Abstract: Semi automatic post hole digger is a agricultural equipment which is used to dig holes. This tool is used to dig holes in the ground, typically from a few inches to a about a foot in diameter, for general purposes such as setting fences and sign posts or planting saplings. The machine mainly consist of motor and auger drill. The main advantage of the equipment compared to older one are it reduce the man power needed to dig holes, reduce the bending of person to apply force and it increase the efficiency of the work.

Title: Arecanut tree climber Authors: BEN AUSTIN B ALAPATT Abstract: The product arecanut tree climber replace the common technology used today especially for arecanut trees . The Product can reach to any desired height without risk to a person or damage to the surface of the tree and harvest at different angles without any risk. The price of the proposed device can be low enough for the climbers to afford. The device according to the present invention will be able to do the work faster, cheaper and much more safely for a much lower price. The design is efficient in climbing the tree very smoothly without damaging the tree.The tree climber doesn’t require a human to physically climb the tree, hence reducing the danger to the climber. The design is simple and appealing to the majority. An unskilled labour can operate the machine safely and efficiently. By installing properly designed sprayers or cutting device many number of trees can be harvested in a single climb thus increasing the efficiency.
