ERGONOMIC STUDY OF BACKHOE LOADER BY MAKING IT DIFFERENTIAL DRIVE
Abstract: We are inspired by the steering mechanism of TANKS used by army "Differential Drive " Here we have tried to deploy this mechanism in BACKHOE LOADER. It is a prototype just to explain differential drive mechanism, to make it more useful and safe while operating. It comes under the branch ERGONOMICS- which is the study of human machine relationship.

Utilizing Heat which is Being Dissipated by Condenser of Refrigerator
Abstract- As we know refrigerator is a device use to keep items at respective temperature, generally at low temperature to preserve items and it is its main function. We have tried to make this device more versatile and efficient, by adding heat chamber. Heat chamber is an external chamber which is installed over our convectional chiller with the help of insulated pillars. We have installed an aluminium chamber over our chiller with the help of insulated pillars and we have wrapped this chamber via refrigerant flow tubes which are coming directly from compressor. Our study have found that refrigerant is compressed up to temperature 30-40 degree Celsius and this hot refrigerant is then allowed to flow through fins which are set at back side of refrigerator for lowering the temperature of refrigerant which is further expanded and allowed to flow through evaporator ( chiller). In this process, this HEAT ENERGY is wasted because of dissipation in atmosphere our experiment involve utilization of this heat in most useful channel.
What we are doing is we are allowing this hot refrigerant to flow through this chamber which is wrapped by the flow tubes by allowing hot refrigerant to flow through this chamber give its heat energy to this chamber making that chamber warm say up to temp 30 degree Celsius. And now this chamber will serve as hot chamber to keep our items warm as per our requirement.
Essentially, the main aim of this review paper is to throw light on the research which can be done on the above explained concept.
