Acoustic emission on the move
Last shot for the inch
Railway inspector wins ndt prize
Cambridge Consultants has just put its acoustic emission testing service on the back of a lorry so that the system can be taken anywhere the roads go instead of needing to be set up at each new site (Fig.2). Before now the service has been used for pressure vessels, bridges, pipework and other structures as well as research. The mobile version, with its own generator, should ease the operation and shorten the time needed. The instrumentation, the Maedas 7, was built at Cambridge Consultants; it is a multichannel zone location system which has proved useful as a prototype (Fig.3).
By October this year there will be almost no imperial sized radiographic film, paper, cassettes or hangers on sale in Great Britain. That is if a plan drawn up by British radiographic suppliers goes according to timetable. The plan, drawn up by the British Photographic Manufacturers Association and the British Photographic Importers Association calls for metrication of smaller sizes (up to 10 x 12 inches) by August and most of the rest of October. The plan is based on British Standard 3490:1972 on sizes of film for industrial radiography and x-ray crystallography. Any further change depends on the International Standards Organization.
