Lead pack film for weld radiography
Photographic camera unit records tv inspection pictures An in-line remote-control photographic camera unit that can be attached to their TS800 inspection television system has been introduced by Telespec. The unit takes high definition and colour still pictures of details that are observed on the television monitor screen and provides higher quality records of faults and construction features than can be obtained by photographing the television pictures directly from the monitor screen. The unit, which has a compact 35 mm single lens reflex camera with motorized drive, can be attached to the front of the cylindrical inspection television camera by screw-thread. No modifications are needed to either the photographic or the television cameras. The television camera 'looks through' the viewfinder of the photographic camera. Thus, in conjunction with the television monitor, it provides a remote 'eye' for the operator when taking photographs. The photographic unit is housed in a waterproofed cast-aluminium case measuring 167 x 120 x 110 mm. Projecting from this are stainless-steel sealed housings for the 28 mm camera lens and two 20 W quartz halogen lamps which provide lighting. A switch provided on the TS800 control unit controls the shutter of the camera remotely. Normally this gives one exposure per switch operation, but by means of the camera's motor driven shutter system a sequence of film frames can be exposed in quick succession.

Mitsubishi market NDTproducts in Europe A compact electron accelerator for industrial radiography, and a series of ultrasonic flaw detectors are the first of Mitsubishi's NDT products to be widely marketed in Europe. Model ML-5R electron linac has an electron beam output of 3 MeV and a maximumx-ray output of 2 0 0 R rain -1. Flaw sensitivity is less than 1% of material thickness between 50 and 22 ram, which is competitive with the performance of betatron and cobalt-60 equipment. The electron beam is focussed on a spot < 1 mm in diameter, giving low penumbra disturbance. Output stability is better than + 5% h -1. The compact unit consists of an accelerator, power supply, cooling system and control assembly, and measures approximately 1.5 x 0.7 x 0.8 m.
Lead pack film for weld radiography Industrial film in lead pack sheets has been announced by Kodak. 'lndustrex' AX film consists of fine grain, high contrast Type 2 film between 0.025 mm lead screens. The packs are ready for immediate use - - there is no need for a darkroom before exposure. A moisture-resistant inner coating helps keep the film dry in adverse weather conditions, and a rip-strip that opens the side of the pack allows easy removal of the exposed film before processing. The film/screen combination is intended for applications such as radiography of welds in steel pressure vessels and pipelines. The pack is flexible and can be formed to suit the specimen being
Models FD-610, FD-610S and FD-630 comprise the FD series of ultrasonic flaw detectors. Each exhibits 100 dB overall gain, adjustable in 0.5 dB, fine gain, steps. Full scale test range is 1 0 10 0 0 0 mm for FD-610 and 610S, 1 0 - 4 2 0 0 mm for FD-630 (longitudinal waves in steel). A range of standard probes, wideband, vertical quartz and vertical ceramic, and angle probes, as well as surface-wave probes, adjustable-angle probes and immersion-type probes, are available for use with the flaw detectors.

X-ray crawlers developed for pipeline radiography Compact x-ray crawlers designed to radiograph girth welds in pipelines from 2 3 5 mm to 558 mm internal diameter are available from Bix and have been developed from the company's original compact crawler introduced in 1977. The crawlers are controlled from outside the pipeline by signals from a low activity, collimated radioactive source. A dual-braking system and advanced detectors are claimed to produce the required positional accuracy. The modular crawlers have CMOS electronic circuitry and a selfdiagnostic fault-finding system, which help maintenance procedures and reduce down-time. Sealed electronics and a design based on reduced power consumption allow the crawlers to be used for extended periods to meet production needs.
