Patent GB-2262339-A (GB)
Title: Method of inspecting the surface of a workpiece
Inventor: KATO NORIHIDE
IPC: G01N21/95
Filed: 1992-12-08
Abstract: A method of inspecting a surface of a workpiece uses apparatus provided with a projecting device for illuminating the workpiece surface with detection light, a detecting device for receiving and detecting the light reflected from the workpiece surface, and a condensing optical system for causing the reflected light to converge on a light-receiving surface of the detecting device. According to the method, the surface inspecting apparatus is successively displaced along the workpiece surface and the reflected light is detected by the detecting device. Further, image data obtained from the detecting device is held and binary digitized. It is determined whether or not the workpiece surface to be inspected is planar. If it is not planar, then the digitized image is processed for dilation and erosion. Thus, when the workpiece surface is curved, faulty or deflective spots can be reliably detected. If the workpiece surface is planar, the time required to process an image can be shortened. The use of windows to define an effective image region and combining windows from several images to increase the area to be processed is also disclosed. <IMAGE>

Title: Protecting nucleic acids and methods of analysis
Inventor: STANLEY CHRISTOPHER JOHN
IPC: C07K14/00
Filed: 1993-12-06
Abstract: A selected region of a nucleic acid is protected from attack by a reagent e.g. a nuclease by complexing to the nucleic acid a nucleic acid analogue which hybridises thereto in a sequence selective manner. The surviving sequence may be detected in an assay, optionally after amplification. A PCR reaction may be sterilised and its product assayed by protecting a characterising region of the product by hybridisation as above followed by nuclease degradation of unprotected nucleic acid. The nucleic acid analogue is most preferably a polymer e.g. a polyamide, polythioamide, polysulphinamide or polysulphonamide to the backbone of which is a bound a sequence of ligands.

Title: Surface treatment of metallic components
Inventor: SHAW NEVILLE
IPC: G21C19/37
Filed: 1994-04-21
Abstract: The surfaces of metallic components for use in a slitter head for stripping a can or cladding from a spent nuclear fuel element in a radioactive and corrosive environment are hardened and then covered by a coating comprising titanium nitride. The components are particularly a slitting wheel 1 and the pin 4 on which the wheel is rotatably mounted.
