New equipment Colour AE s o f t w a r e uses structural diagrams Pictorial colour software for acoustic emission testing has been launched by Physical Acoustics Corporation of Princeton, N J, USA. The software can either employ a digitizer for arbitrarily defined pictorial shapes or have predesigned figures incorporated in it. The pictorial software has been designed as an upgrade to PAC's SPARTAN AE system and is currently being used to proof test US Air Force F-111 aircraft. Until now, AE systems could only show AE sources relative to sensor placement. The pictorial format, however, now shows the locations of AE sources within one or more diagrams of the structure. AE location plots,
which were previously obscure, are now easier to understand. By providing a pictorial format, the software allows twodimensional or three-dimensional AE analysis directly against the test structure itself. Large or small, solid or hollow structures can be tested. Standard applications for the software include proof testing and aerospace composite structures, utility bucket truck testing, air frame fatigue tests, materials research and load testing of petrochemical vessels. With this software, the SPARTAN user can place up to 128 sensors on the predefined structure diagrams as well as define parameters of analysis. The software supports linear or
Pictorial colour software system from PAC rectangular location algorithms and produces real-time screen updates. For more information contact: Peter Eleftherion, Physical Acoustics Corporation, PO Box 3135, Princeton, NJ 08543-3135, USA
Portable ultrasonic f l a w d e t e c t o r s a n n o u n c e d Portable ultrasonic flaw detectors have been announced by NDT Instruments of California, USA.
Strain gauge rosettes designed to overcome the problem of strain gradients on measured surfaces for stress analysis have been introduced by HBM. The devices are constructed by superimposing the necessary three grids on top of one another. The RY91 and RY93 rosettes therefore overcome problems associated with the positioning of strain gauges on areas with surface gradients, The grid thermal coefficiency is matched to ferritic steel for the RY91 and aluminium for the RY93. Both are available in grid lengths of 3, 6 or 10 mm with a nominal resistance of 120~. Hottinger Baldwin Messtechnik, Station Approach, Bicester, Oxon OX6 7BZ, UK

The pulsar series consists of the miniature 5000 or the full capability 5500. Both models are battery or ACpowered and suited for a wide variety of inspection applications in the shop or field. Metals, weldments, nonmetals and composites can be nondestructively examined. Inspection procedures include flaw detection, corrosion assessment and thickness gauging. The Pulsar 5000 has a flaw monitor with an adjustable bar gate and visible/audible alarm, while the Pulsar 5500 offers a wide host of features, including a 3-mode DAC (distance amplitude correction), digital readout for flaw distances or sectional thickness, weld triangulation controls (for digital display of soundpath, flaw depth and surface distance), linear reject, initial pulse/interface sync and a flaw monitor with adjustable bar
gate and visible/audible alarm. NDT Instruments Inc, 15622 Graham, Huntington Beach, CA 92649, USA
Special alloy road w h e e l s inspected b y X - r a y s y s t e m Inspection of special alloy road wheels manufactured near Istanbul, Turkey, is to be carried out using an X-ray inspection cabinet purpose-built by Errington Laboratories of Burton, UK. Valued at nearly £60000, the cabinet combines video and X-ray equipment, is semi-automatic and is designed to handle batch production. The equipment includes a 160 kV X-ray set, an imaging system linked to a TV camera and a manipulator to position the wheels. The wheel is loaded manually and the X-ray of the wheel viewed in real-time on a TV monitor.
