摘要： A method for the removal of embedded contamination from a metallic surface in which a laser beam is directed onto the contaminated surface. The laser beam has sufficient power density to cause direct ejection of laser-generated melt pool liquid from the metallic surface thereby removing a metallic surface layer containing the embedded contamination. Means are provided for the collection of laser ejected material in order to prevent recontamination of the metallic surface or contamination of previously uncontaminated surfaces.

摘要： A rotor (10) comprising a cylindrical structure (30, 31) including a portion made from a fibre reinforced composite (38, 39) wherein magnetic filler material is incorporated within the matrix (44) of the composite and wherein the loading of the magnetic filler material varies through the matrix whereby the average mass per unit volume of the structure (10) decreases with distance radially from the axis of the structure (10). As a result, strain matching across the rotor can be achieved even when the rotor is spinning at high speed, such as when used in a flywheel energy storage and conversion apparatus.

摘要： A rotary kiln, particularly for producing uranium dioxide from uranium hexafluoride, has an inlet arrangement (1) and a heated rotatable barrel (14). Uranium hexafluoride and steam react together in the inlet arrangement (1) to form uranyl fluoride which is fed into the barrel (14) by the aid of a rotating scroll feed device (17). In the barrel, the uranyl fluoride reacts with a counterflow stream of steam and hydrogen to produce the uranium dioxide. A porous metal or ceramic filter (28) closely surrounds the scroll feed device (17) to remove particles from kiln-produced gases. The filter is maintained in a clean condition by the scraping action of a number of helical blades forming part of the scroll feed device (17). The uranium dioxide powder produced by the kiln may be processed to form nuclear fuel pellets.

摘要： The invention provides improved magnetic bearings intended to function successfully at elevated temperatures, particularly temperatures in excess of 600 DEG C. The invention provides the magnetic bearing in the form of a number of decoupled magnetic circuits with an increased slot area, and winding level, for the upper magnetic circuit so as to provide the upward force and regulating force. The extra windings available allow the level of losses sustained to be reduced as the biasing windings can be successfully operated at a current density approximately half that of the regulation windings.
