Heat In Thames Water To Warm Festival Hall
By A STAFF CORRESPONDENT IN LONDON
The grey Thames water swirling past the piers of Hungerford Bridge is soon to be used to heat the great Royal Festival Hall (capacity 3.500), standing nearby on the South Bank exhibition site.
The plant, which can be described as a giant refrigerator working in reverse, is known technically as a heat-pump. It was designed by the scientific staff of the Fuel and Power Ministry as part of its fuel-conservation programme, and tests indicate that it has a thermal efficiency in the region of 150 per cent. - which means that the heat generated exceeds by one half the amount of fuel used to produce it.
Although the possibilities of the heat-pump - in principle quite a simple device - have been known for nearly a century, this is the first attempt to prove on a large scale its commercial possibilities. The high cost of pioneering and of manufacturing the considerable number of working parts required in such a heating system, which has to be specially designed to the requirements of a building, has discouraged its development by commercial firms. However, the scientists and engineers associated with the Festival Hall project say that three months of experiment have proved its efficiency and have opened up practically unlimited commercial prospects for the system.
This achievement can perhaps best be evaluated in the light of Britain's critical fuel shortage, intensified in recent months by the added strain of rearmament. Against the 150 per cent, heat efficiency of the heat-pump, the efficiency of the millions of tons of coal burnt annually in the open grates is approximately 15 per cent.; and that of the huge amount of electricity consumed by electric fires is less than 30 per cent.
The heat-pump system contains the equivalent of the main parts of the mechanical refrigerator a condenser and evaporator containing a refrigerant, also a compressor. The difference is in the layout. In a refrigerator the evaporator is in the cabinet and cools it by absorbing heat and passing it by means of the refrigerant to the condenser outside, which dissipates it into the atmosphere. In the heat-pump system the process is reversed. The liquid refrigerant, which will boil at a low temperature and pressure, is circulated through this system by the compressor.
The river water, piped through the evaporator, is of sufficient temperature to make the liquid refrigerant boil and vapourise. The vapour then passes through the compressor, which builds it up to a maximum pressure of 285 pounds a square inch in the condenser. Under pressure it condenses at a temperature of 165 Fahrenheit and releases the heat it has gained from the river water. This heat is in turn absorbed by water circulating in another system of pipes leading from the condenser to the hall, where it is finally released. The refrigerant liquid returns to the evaporator through a valve which reduces the pressure, thus turning it back into vapour, and the cycle is set off again by the initial heat absorbed from the river water.
Two Rolls Royce Merlin en- gines, modified to run off the mains gas, supply power for the system. A waste-heat boiler transfers further heat, generated by the exhausts of both Merlins, to the water circulating in the hall.
But this is not the end of the story. By a simple adjustment of the heat-pump, the roles of the condenser and the evaporator can be reversed so as to cool the hall.

Handling Specialty was approached by a US-based material handling company to custom engineer and manufacture an overhead three-stage inverted belt lift with attached tooling (which rotates), that holds a part as it goes through an intensive cleaning and coating process.

The winch can be detached from the crane and fed out the rear where the two slopes meet.
Soldiers from the Bowling Green-based 189th Engineer Company, 276th Engineer Battalion, 91st Troop Command conduct new equipment training on the Dry Support Bridge system at Fort A. P. Hill April 19, 2013. During the two-week certification course taught by representatives from WFEL, the bridge manufacturer, Soldiers spend time in the classroom as well as in the field to learn how to set up and take down the bridge. At the same time, unit mechanics conduct training on how to maintain the new equipment. The new bridge takes less personnel and less time to set up than the previous system, and the company also has a float bridge system in their inventory. A total of 32 Soldiers are expected to complete the certification and then will train additional Soldiers in the company during their annual training in June.

The Big Bang @ Parliament, part of Tomorrow's Engineers Week, highlighted some of the great projects that young people are doing in science and engineering. The event featured a number of MPs including Nick Boles, Andrew Miller, Liam Byrne and Chi Onwurah.
Four engineers from the U.S. Army Corps of Engineers Baltimore District participated in the judging and coordination of the Mid-Atlantic Future City competition at the Baltimore Museum of Industry. The Future City Competition is a national, project-based learning experience where students in 6th, 7th, and 8th grade imagine, design, and build cities of the future. Students work as a team with an educator and engineer mentor to plan cities using SimCity™ software; research and write solutions to an engineering problem; build tabletop scale models with recycled materials; and present their ideas before judges at Regional Competitions in January.

Reuben Lucius Goldberg (b. July 4, 1883 – d. December 7, 1970) was an American cartoonist, sculptor, author, engineer and inventor.
He is best known for a series of popular cartoons depicting complex gadgets that perform simple tasks in indirect, convoluted ways.

Nuclear Engineer in Argonne's Nuclear Engineering Division. Sumner is a member of the research team that has developed a modern suite of computer tools--called the SHARP Reactor Performance and Safety Simulation Suite--that digitally mimic and allow researchers to “see” the physical processes that occur in a nuclear reactor core, including neutron transport, thermal hydraulics and fuel and structure behavior. Argonne's high-fidelity computer modeling and simulation work in support of advanced nuclear energy systems is a natural outgrowth of the cumulative years of Argonne's expertise in nuclear energy.
CODRU, Moldova – Troopers assigned to Regimental Engineer Squadron, 2nd Cavalry Regiment conduct small arms maneuver tactic drills with Soldiers from Codru Engineer Battalion May 12, 2016 at Codru Engineer Training Area during exercise Dragoon Pioneer. One squad takes cover and suppresses fire as the other bounds forward. They continue in a leapfrog fashion until they reach their objective. The Squadron is training with the Moldovan Army for three weeks in order to demonstrate the United States commitment to our allies and to develop relationships built on trust while building readiness.

and i know that making heart with bangle on book is known to many of you.....perhaps....
i have done it while load shedding...with bangle on my circuit book.....with my Nokia 1203 and 5220 cellphone...
yes!! with the torch light of 1203 and
2 MP camera of 5220 ..........
i m confused about the title .....
