Royal Air Force Valley, Anglesey, has moved to meet Nato?s Stanag 3316 agreement by replacing a centralised standby generator on its aeronautical ground lighting systems with five diesel generators.

Supplied to Amey BFPO Services, RAF Valley?s works service management company, the generators are able to restore power to localised areas around the site within 15 seconds of a power cut.

?We went out to competitive tender with a very stringent specification, which very few companies were able to meet,? said John Leathwood, electrical engineer for Amey Facilities Management.

?Scorpion Power Systems won the tender as it was able to provide the best value for money, has an excellent track record and the experience and expertise to undertake such assignments.?

Previously, RAF Valley relied on a single generator. This left the system vulnerable in the event of a localised power failure, as the central system wouldn?t detect the fault and the power would remain down. The use of five separate generators increases the security of supply and also enables localised maintenance to be carried out without disrupting the entire system.

Britain?s nuclear industry is accused of complacency after claiming the problem of radioactive particles discovered outside the Dounreay nuclear plant is not harming attempts at the environmental clean up.

The UKAEA has to return the Caithness complex to a near-greenfield site within 50 years at a cost of ?4.5bn.

Since 1983, over 200 radioactive hotspots have been found on the foreshore at Dounreay and approximately 50 more on the nearby Sandside beach, which is open to the public. A further 750 have been discovered on the seabed during surveys and it is thought that up to 50,000 may be in the sediment close to Dounreay.

The infamous pit in to which scientists for many years discarded radioactive material was originally thought to be the source of contamination.

Lorraine Mann, the convener of Scotland Against Nuclear Dumping, said it shows a quite extraordinary level of complacency by the new management of the clean up team and ?reveals that they have no grasp of the magnitude of the problem they are facing.?

Dounreay yesterday opened a ?7.5m plant to control and dispose of low-level effluent from the decommissioning of the plant.

Energy supplier npower will increase average domestic prices by 5.8% for electricity and 5.2% for gas.

Electricity prices will not rise until 1 April, whereas gas prices will go up from 1 February. Small business customers will experience a similar increase.

Andrew Duff, chief executive of RWE Innogy, npower's parent company, says the increases reflect a rise in wholesale energy market costs, which have risen by 20% year-on-year.

Duff says other factors are the rise in gas transportation costs, which will go up by 5% this year; renewable energy obligations; and energy efficiency programme costs.

The increases amount to around 29p per week for the average domestic electricity user and 34p per week for the average domestic gas user, based on an average annual residential usage of customers on standard domestic tariffs of 3,300kWh for electricity and 20,500kWh for gas.

An average of 2,500 manufacturing jobs are lost every week, a situation that is not sustainable, says Derek Simpson, general secretary of Amicus. Addressing a conference in Scarborough, the union leader said the decline of the UK

Styles and Wood has hired mast booms to complete the electrical installation at the new 20,400m? Debenhams store, part of the redevelopment of Birmingham?s Bull Ring. The company is using HM10 mast booms to provide high-level access to wiring and lighting over the store?s open central staircase.

The HM10 was chosen from Nationwide Access because the machine?s weight does not exceed the store?s floor loading. It provides a 10m working height and a 3m outreach and weighs 4.2 tonnes.

Being electrically powered, the machine is suitable for use inside buildings, where diesel exhaust emissions would be unacceptable. It is also small enough (its closed width is just 0.81m) to fit into the store?s goods lift. The platform measures 1.02m by 0.79m for an electrician, his tools and the light fittings.

Twelve U.S. states sued the Bush administration on Monday in an attempt to prevent changes to the Clean Air Act that would allow increased pollution from fossil-fired power plants and factories. The revisions will weaken air pollution standards and harm public health. The Environmental Protection Agency brought in new standards to coal-fired utilities and oil refiners to significantly expand aging facilities without installing pollution-reduction equipment. The lawsuit said that only Congress could make major changes in air pollution policy. EPA officials contend the new rules will not increase power plant emissions. Last week, a separate group of states sued the Bush government to force it to regulate greenhouse gas emissions. "We should not be relaxing emission control standards when air pollution continues to cause such devastating health and environmental problems," New York Attorney General Eliot Spitzer said. "Litigation can produce nothing but confusion," utility lobbying group Electric Reliability Coordinating Council said in a statement.

WF - the fifth emergency service this Christmas


Reasoning that emergencies seem to strike at the worst possible times, WF Electrical has decided to open 21 branches over the forthcoming holiday period.

Director and general manager, Richard Edwards decided that, in an effort to give its customer the best possible service when they need it most, the company will open strategically selected branches between 8:30 and 12:30 from the 29th to the 31st December.

Customers who need assistance can ring 0207 613 3321 for details of their nearest open branch. The branch can arrange, via WF Express, for the customer to collect items from stock held at WF's national distribution centre in Dagenham up to 2:00pm or for them to be dispatched by courier.

Daihatsu?s latest van offering is the super-compact Extol.

Priced at ?6,995 (ex vat), the 1.3 litre, 93mph-capable Extol is billed as an eventual replacement for the successful Hijet micro-van ? a What Van? award-winner for 11 successive years.

Daihatsu says its primary target for the model are multi-drop delivery operators plus city-centre businesses who will appreciate the Extol?s compact external dimensions and a class-beating 8.8m kerb-to-kerb turning circle.

Large sliding doors on both sides plus a high-opening top-hinged tailgate enable easy cargo access ? especially in tight spaces such as narrow back streets. The flat steel load floor is vinyl-covered and also features a substantial storage space underneath, meaning bulky tools can be kept out of site for added security.

Cargo dimensions are 1,700mm load length, 1,175mm load height from floor to roof, with 1,330mm width. Excluding the underfloor storage space, the cargo capacity is 2.2 cubic meters.

Also included are driver and passenger airbags, power steering, central locking and radio/CD player, plus a three-year/60,000 mile warranty.

Last week you had a story from ABB about a new surgical technique for children suffering from osteosarcoma, a form of bone cancer. Many of you asked for more technical detail.

Surgeons replace a section of diseased bone with an adjustable insert that allows the bone to be lengthened, keeping pace with the healthy limb. In the past, this involved frequent surgery to access the implant and operate a screw jack to lengthen it.

Engineers at the University College London, based at the Royal National Orthopaedic Hospital at Stanmore, have produced an implant that can be activated by electromagnetic induction.

The ?bionic bone? has a miniaturised high-ratio gearbox driven by a rare-earth permanent magnet synchronous rotor no larger than a one pence piece and 4mm thick. The gearbox is only 21.5mm diameter and 18.5mm long and drives a power screw which lengthens the ?bone?, developing the 200 Newton force required for every 1mm of extension. The complete rotor / gearbox assembly is embedded within the implant and activated by applying a rotating magnetic field .

The patient?s leg is inserted into a cast-resin three-phase stator, powered by a Danfoss VLT 2800 variable frequency inverter. The variable torque control of the drive enables the rotor to produce sufficient torque to drive the gearbox at as low as 40 to 60 volts at 50Hz, and provides accurate flux control to protect the tiny gearbox from torque overload. To ensure smooth rotation at this low stator voltage, the drive output waveform is filtered before being applied to the stator.

A single-phase to 3-phase VSD is essential so that the stator can be powered from a domestic 240v single-phase supply.

With gearing of 13,061 : 1 and the rotor spinning at 3,000 revs, the gearbox develops 4Nm torque and extension of 0.25mm per minute is achieved and timed rather than measured. Despite the asymmetrical air-gap, and the tissue of the leg, between the stator and the Niobium Iron Boron (NdFeB) rotor, there is excellent magnetic stator / rotor coupling, regardless of the fit of the patient?s limb within the stator and so there is no need for immobilisation or discomfort for the patient during a typical 15 minute treatment.

The cost of the implant is ?12,000 against ?4,000 for initial surgery but savings in subsequent surgery and aftercare offsets the cost.

Cooper Bussman's fuses had a hand in helping the Rolla Solar Car Team from the University of Missouri win the 2003 American Solar Challenge Race.

The challenge was to build a solar powered car and race it approximately 2,300 miles from almost one side of the USA to the other. The course took them from Chicago in the east, to Claremont, a suburb of Los Angeles, in California. The Missouri team took just 51 hours, 47 minutes and 39 seconds, beating the previous race record by more than four hours.

Busmann donated a number of its FWX series 80A semiconductor fuses to provide circuit protection for the solar vehicle.
