A bucket elevator is a conveyor for carrying bulk materials in a vertical or inclined path. Bucket elevators for the mechanical, vertical transportation of materials have become a crucial link in the production process in many industrial sectors. Typical elevator consists of: 1. An endless belt, 2. A chain or chains, to which buckets are attached, 3. Necessary loading and discharging terminal machinery, 4. A drive arrangement, 5. Supporting frame or casing. Material is fed into an inlet hopper. Buckets (or cups) dig into the material, and convey it up to and over the head sprocket/pulley, then throwing the material out the discharge throat. The emptied buckets then continue back down to the boot to continue the cycle. Industrial Bucket Elevators are made in a variety of shapes, weights and sizes, utilizing centrifugal buckets or continuous buckets. The belt can be made of natural fibres, rubber, plastic or metal. Centrifugal Bucket Elevators are most commonly...

GATE 2013: GATE Study material for Strength of Materials This article is on study material of mechanical engineering subject, 'Strength of materials'. This subject is one of the most important subject of mechanical/civil engineering due to basics of engineering is associated with it. Here I am sharing my study material/notes during GATE preparation in 2006, when I was in final year.

CATIA products are based on the open, scalable V5 architecture. By enabling enterprises to ...

BAE Systems has helped the GB Taekwondo team evaluate the electronic scoring vest used in major international competitions. The relatively new system introduced into Taekwondo requires fighters to wear electronic socks that deliver a coded signal when they strike sensors on the opponent’s vest. According to the defence company, the sport has never fully understood how this functions and how to fully optimise appropriate tactics. As part of a £1.5m technology partnership with UK Sport, engineers and scientists from BAE Systems’ Advanced Technology Centre in Bristol spent more than six months testing the electronic scoring vest using equipment usually used to test composite materials’ resistance to impact. This has allowed the GB Taekwondo team to adjust its training style to maximise methods needed to score on the vest, giving the team a marginal gain in competition. Kelvin Davies, BAE Systems’ project leader of the UK Sport technology partnership, said: ‘We found that ...

E2v provides imaging sensors for SACLA XFEL project E2v is to provide imaging sensors to form part of the next generation of focal plane imaging sensors in the Spring-8 Angstrom Compact free-electron Laser (SACLA), an X-ray free-electron laser (XFEL) located in Hyogo Prefecture, Japan. The XFEL is a joint project between Japanese natural sciences research institute RIKEN and the Japan Synchrotron Radiation Research Institute. SACLA became available for use by worldwide researchers in March 2012.

Renewable energy could fully power a large electric grid 99.9 per cent of the time by 2030 at costs comparable to today’s electricity expenses, according to new research by the University of Delaware (UD) and Delaware Technical Community College. A well-designed combination of wind power, solar power and storage in batteries and fuel cells would nearly always exceed electricity demands while keeping costs low, the scientists found. ‘These results break the conventional wisdom that renewable energy is too unreliable and expensive,’ said co-author Willett Kempton, professor in the School of Marine Science and Policy in UD’s College of Earth, Ocean and Environment. ‘The key is to get the right combination of electricity sources and storage — which we did by an exhaustive search — and to calculate costs correctly.’ According to a statement, the authors developed a computer model to consider 28 billion combinations of renewable energy sources and storage mechanisms, each tested...

Basic concepts in Thermodynamics This article deals with basic concepts in engineering thermodynamics. The study of thermodynamics is very much important in thermal engineering specialization in M. Tech or M. E level. So, GATE exam offer more importance to this subject and its related topics. Follow the below mentioned basic concepts taht will help you  in GATE 2013 Exam. What is Thermodynamics? Why to study Thermodynamics? Thermodynamics deals with relations between heat and work. It predicts many relationships between properties of matter. Thermodynamics systems and surroundings : thermodynamics systems: it is defined as any prescribed and identifiable collection of matter upon which attention is focused for investigation. Basic Concepts in  Engineering   Thermodynamics - Mechanical Engineering   In the polytropic process we have pvn = constant, if the value of n is infinitely large, the process is called c...

A US solar energy start-up has developed a technique for manufacturing its ‘spray-on’ photovoltaic windows. New Energy Technologies believes the technique should lead to higher production speed, lower overall costs and greater durability of the end product. ‘These achievements have moved us closer to our manufacturing, scale-up, and power production goals — all-important factors to advancing our Solar Window technology towards commercial launch,’ said John Conklin, chief executive officer at New Energy. In collaboration with the University of South Florida and the US Department of Energy’s National Renewable Energy Laboratory (NREL), the company previously debuted its Solar Window technology — based on an organic photovoltaic solution that can be sprayed directly onto glass as an incredibly thin, sub-micrometer layer. The next challenge was to attempt to develop methods for scaling up the fabrication method. Vacuum deposition is both expensive and time consuming and, t...
