A system for the non-destructive inspection of a conveyor belt which includes a cover on the carrying side, a cover on the backing side, each cover being made of elastomeric material, and embedded tension members. While the conveyor belt is moving, a radiation source emits rays to the belt surface which are of such high energy that the rays pass through the belt within a region free of material disposed on the belt. A sensor detects the rays passing through the belt. A processor is operatively connected to the sensor and evaluates the result of the radiographic check. The radiation source and the sensor are accommodated in a housing, wherein, between the radiation source and the sensor, there are two housing openings through which the moving belt runs without contact.

Regular in-service inspection is important to verify the integrity of welded nozzle sections in nuclear and other safety critical facilities. Nozzle sections made from austenitic steel can be susceptible to rapid crack growth due to thermal fatigue and stress corrosion. Early detection of cracks is therefore essential to ensure the continued safe operation of the facility in question. In order to reduce the time and cost of such inspections there is an urgent need to develop a system capable of performing a full inspection of nozzles without the need to change probes. The aim of NozzleInspect project is to design an autonomous robot system that able to: reduce the inspection times, Improve defect delectability and sizing, Reduce human intervention which will reduce workforce radiation uptake and Reduce requirement for robotic manipulation and consequently reduce size and cost of robotic deployment system. The goal of NozzleInspect project is to improve the reliability of the inspection of the welded nozzle sections in nuclear and other safety critical facilities. The robot will carry out a new and novel flexible phased array probe to allow a full inspection of nozzle weld areas and an advanced navigation system that follow the weld in nozzle. The presence of defects in these parts could lead to catastrophic component failure.


A conveyor belt has a carrying side cover plate and a running side cover plate each of a polymer material having elastic properties. The conveyor belt defines a conveyor belt longitudinal direction (X) and has an embedded reinforcement and at least one of the cover plates is provided with a hybrid conductor loop. The hybrid conductor loop communicates in a contactless manner with an interrogation station in the form of a transmitter/receiver pair. The hybrid conductor loop has a flattened conductor cross section and runs in the conveyor belt obliquely at an angle () relative to the conveyor belt transverse direction (Y) to form a diagonal direction (Z). The transverse direction (Y) is at right angles to the longitudinal direction (X). The arrangement of the transmitter/receiver pair is adapted to the diagonal direction (Z) to so increase the mutual spacing of the transmitter and the receiver.

The structural integrity of wheel sets used in rolling stock is of great importance to the rail industry and its customers. A number of rail accidents have been directly related to the failure of train axles, leading to increased demands for their inspection and maintenance. Visual inspection and Magnetic Particle Inspection are the current standard practices used for manual non-destructive testing of axles. However, these processes require removal of the wheelset from the wagon/locomotive bogie and full disassembly in order to facilitate access. Inspection is also carried out by some wagon providers using ultrasonic testing (UT) but its application is also limited to disassembled wheelsets. An axle on a wheelset can be connected to a number of ancillary components including breaks and bearings. The disassembly (and reassembly) of axles from the wheelsets/wagon bogey is therefore very time consuming and expensive. There is evidence that even partial disassembly and reassembly could introduce future axle reliability problems. To minimise disruption to their train services but ensure continued safety, train operators require frequent and regular inspection methods that allow quick inspection at the depot with the minimum of wheelset and bogie disassembly. The AxleInspect project aims to develop new inspection techniques based on phased array ultrasonic and electromagnetic techniques suitable for the inspection of both solid and hollow axles. For solid axles, inspection techniques are to be developed that inspect from the end face of the axles using new and novel phased array ultrasonic inspection technology. For hollow axles, probes based on UT and electromagnetic inspection techniques are to be developed, enabling detection of surface breaking cracks that cannot be found by ultrasonic inspection. These new techniques will allow inspection of axles whilst they are still attached to their supporting bogey, allowing minimal wheelset disassembly from the train.
