1. s financial world Graeme Allinson head of manufacturing transport and logistics at Barclays Commercial Bank has confirmed he will be presenting at the shows to talk about what banks look for when they lend money Commenting on his presence at the show he said I am delighted to be presenting at the 2010 exhibitions Visitors to these shows are confronting a difficult economic situation and this is a fantastic opportunity to give them a comprehensive insight into what banks look for when they lend money Barclays Commercial Bank remains dedicated to increasing lending so that our clients are able to pursue their business agendas indeed our lending was up 10 per cent in the first half of 2009 compared with the same period last year and we are focused on getting closer to our clients than ever before Other speakers include Geoff Walker representing the Institution of Diagnostic Engineers the Carbon Trust s head of financial services Paul Higgins Chris Dee executive director of the British Compressed Air Society lan Morris of the British Fluid Power Association Professor Len Gelman director of Centre of Vibro Acoustics and Fatigue at Cranfield University Stephen Barker representing Gambica Trade Association Matt Gallagher CEO of The British Institute of Non Destructive Testing Bindt plus many more For the most up to date information on the seminar programme and to register your interest for attending a par2.

3. to each other is best described in the following way If it is considered that at any given temperature the sum of the radiation of the three emission types is equal to one and it is assumed that solid bodies transmit negligible radiation the transmitted element can be treated as zero Therefore the heat energy coming from an object only comprises emitted and reflected radiation It is now easier to understand why objects such as polished and shiny metals can only have a low emission or emissivity as radiation from the Surrounding environment is strongly reflected and so proportionally high by these surfaces For example the typical emissivity for freshly milled steel at 20 C is 0 2 reflected energy would be 0 8 This means 80 of the emitted heat energy from the object would be reflected heat energy from surrounding objects However at a much higher temperature of 1 100 C the same material will have a typical emissivity of 0 6 In contrast objects such as textiles or matt black surfaces reflect very little and therefore emit a high proportion of the heat energy Emissivity of a black matt paint at 100 C Is typically 0 97 and so is much more suited to non contact temperature measurement Many low cost devices have fixed emissivity correction of 0 95 which makes them unusable for almost all accurate temperature measurement tasks Wavelength The previous description of emissivity is rather simplistic in
