All round perfection

Teledictor has introduced an eddycurrent crack detector designed for semi-automatic testing of cylindrical components, whether turned, forged or cast. The equipment, the Type 892, rotates the part on nylon rollers which can be adjusted to suit the length of the test piece. A probe holder, mounted beneath rotating shafts and driven by a pneumatic cylinder, with controlled rate of movement, enables the probe to traverse any part of the cylindrical component's outer diameter curing rotation. The unit can be adjusted for component's from 10-50 mm in diameter up to 20 mm long. It is automatic in operation once the component is placed on the rollers and the start button pressed. If a crack is found a monitor lamp lights, or an output can be used to activate a conveyor. The company claims a possible testing rate of one component in 3 s. The sensitivity level can be adjusted (Fig.l). Teledictor Ltd, Groveland Road, Tipton, Staffs, UK

The American company K. J. Law Engineers has introduced an eddycurrent equipment designed to detect cracks and seam-type defects in bolts. The equipment the Model 1944 is semi-automatic and sorts the bolts into flawed and sound categories. The machine is hand loaded and has a nominal inspection rate of 1000 parts per hours. The parts tested can be from 19-38 mm diameter and up to 355 mm long. The adjustment to size takes up to 20 minutes. The testing instrumentation is the Vermiter 730-11 dual channel crack and seam detector with a rotary transformer coupling between the test probe and the test instrument. Two non-contact Vermit test probes scan each test piece (Fig.3). K. J. Law Engineers Inc, 26341 W Weight Mile Road, Detroit, Michigan 48240, USA
200 kV up and about
The Balteau Electric Corporation of Stamford, Connecticut, USA, has introduced a portable 200 kVp portable x-ray unit to the American market. The unit, the B G - 2 0 0 C has an operating range of 4 0 - 2 0 0 kV at a constant 5mA for steel up to 25 mm thick using a lead screen and finegrain film at 915 mm for 300 s exposure. The x-ray head is oil insulated with oil circulation with further extension by water cooling. The unit is used with the BG-11 control panel. The x-ray head weighs 48 kg and the control panel 19 kg (Fig.2). Balteau Electric Corporation, 63 Jefferson Street, Stamford, Connecticut, 06902, USA

at up to 154.84 cm 2 at a time. The articulated legs can be adjusted for a span of 2 5 - 2 5 0 mm for a good contact on most surfaces. The yoke switch is triggered as the wet or dry medium is applied. The yoke measures 220 x 190 mm and operates from 115 Vac, 60 Hz power supply at less than 6A or o f f a 12V car battery. It is equipped with a 3 point grounded plug on a 7.6 m cord. The switch is enclosed in rubber and there is only magnetic contact with the test piece. Hence no arcing is possible (Fig.4).

postal terror
The Belgian company Balteaux has introduced an x-ray unit designed to inspect postal packets. It measures 460 x 560 x 500 mm and runs off a mains supply. It accepts packets up to 35 mm thick by 280 mm wide. The packets are taken through the machine on a hand controlled conveyor. The packet is viewed through a fluorescent screen by a mirror grid lead glass optical system. The voltage can be chosen from 55, 60 or 65 nV for different thicknesses. The machine is shielded to make it safe for use by people untrained in radiography and it is heavily built as protection against mild explosions (Fig.5).
