An economical, flexible, magnetostrictive sensor for use on planar and/or curved structural surfaces, for guided-wave volumetric inspection of the structure. The flexible plate MsS probe includes a flexible strip of magnetostrictive material that is adhered to the base of a flat, flexible, conductor coil assembly. The conductor coil assembly has a core that is composed of a thin flexible strip of metal, a layer of an elastomeric material, and a thin permanent magnet circuit. The flexible core is surrounded by a flat flexible cable (FFC) that is folded and looped over the layers of the core. The exposed conductors at the ends of the FFC are shifted from each other by one conductor and joined so that the parallel conductors in the FFC form a flat, flexible, continuous coil. The entire probe assembly may be bent to match the curved contours of the surface of the structure under investigation.

A structure and system are described which include the use of a combination container for sequentially dispensing multiple fluids onto a removable applicator device. A preferred application of the invention is with the sequential dispensing of a quantity of disinfecting solution over a toothbrush, followed by the dispensing of a measured quantity of toothpaste onto the toothbrush. The device is constructed in a double walled cylindrical (circular or non-circular) configuration with a hollow plunger component coaxially positioned within the cylindrical walls. Beneath the plunger component is contained a quantity of disinfectant solution such that when the plunger is directed downward the disinfectant solution is forced upward between the walls of the double walled container and through dispensing ports directed into the interior where the applicator is positioned. The contained motion of the plunger component downward under the directed force of the applicator brings the base of the hollow plunger into contact with the base wall of the container and causes the collapse of the hollow plunger. A second liquid/gel contained within the hollow plunger is then directed up and out of its enclosed volume through ports aligned with the applicator.

A main body of a nondestructive inspection apparatus is positioned on a spray line header connected to a thermal sleeve within a cooling water inlet nozzle , and fixed to a core spray line by vertically clamping the core spray line with fixing units at the position where the thermal sleeve to be inspected is located. Scanners insert a tape probe having an inspection head inside an annular gap formed between the thermal sleeve and the cooling water inlet nozzle in an axial direction. The scanners are guided by guide rails to move the tape prove so that the inspection head can move in the circumferential direction of the annular gap

An inspection apparatus performs a visual inspection on inner structural members of a large-scale system from the outside without disassembling the system. The inspection apparatus includes a screw device formed in a tube-like shape which engages with surfaces of internal structural members of the large-scale system while advancing into a narrow pathway of the large-scale system when inserted in the narrow pathway and applied with a rotational force, a video scope having a camera at its end which is inserted in the screw device and protrudes from an end of the screw device to capture images of surfaces of the internal structural members of the large-scale system, and a video monitor for displaying the images from the video scope and controlling a direction of the end of the video scope.

A conforming eddy current testing (ECT) probe for performing eddy current testing when placed on the surface of a test object. An eddy current array is fabricated on a flexible substrate. A shape metal alloy (SMA) piece is manufactured to have an original shape that conforms to the surface of the test object, and then affixed to the substrate. The SMA piece has as much or more flexibility than the substrate, so that it can be manipulated into position. Just prior to testing, the SMA piece is actuated to revert to its original shape.
