摘要： Process for producing colour change devices incorporating areas of contrasting appearance, and the devices so produced. The process involves masking limited areas of a layer (10, 28) of a colour generating metal (e.g. Ta or Nb, especially commercially sputtered Ta foil), with a mask (11) made of a material which permits anodization of an underlying surface and permits penetration of fluoride as an adhesion-reducing agent at levels employed in the process. The masked metal layer is anodized to form an anodic film (14, 29) on the metal, the anodization being carried out in an electrolyte containing fluoride at a concentration high enough to (a) weaken the adhesion of the anodic film to the underlying metal over the entire area of the film, and (b) to introduce voids in the anodic film in areas not covered by the mask to reduce the density of the film in these areas compared to areas covered by the mask. Finally the mask is removed. The device can be used, for example, as a product identification code which can be made to disappear after use.

摘要： A microwave tunnel oven (10) receives a series of packages (24) each comprising a container and a load in the container to be heated by microwave energy. The oven (10) has a conveyor (18) with a series of carriers (20) each for receiving one of the packages (24) and conveying it through the oven (10). The improvement comprises modifying the microwave field in the load during its irradiation in the oven (10) in a manner to generate higher order modes of microwave energy in the load to enhance the uniformity of heating throughout the load. The structure for achieving the field modification is divided into two parts, one part being formed on the conveyor (18) and the other part being formed either on the package (24) or on a subsidiary conveyor (26) that extends parallel to the main conveyor.

摘要： A novel method is described for joining aluminum to metal surfaces by brazing. The method comprises (a) applying as a coating to at least one of the metal surfaces to be joined a mixture of a metal (e.g. Si, Cu or Ge) and a brazing flux, the metal of the mixture being adapted to form a brazable eutectic with one or both of the surface metals, (b) heating the surfaces and the coating in juxtaposed relation to a temperature above the brazing alloy melting point to thereby dissolve oxide film on the surfaces to be joined, cause the metal of the coating to dissolve into the oxide-free aluminum surface and form therewith a brazing alloy layer and form a brazed assembly and (c) cooling the brazed assembly to form a solidified joint between the surfaces. This has the advantage of providing for the joining of metal surfaces, such as aluminum, to aluminium, copper, brass or steel surfaces, by brazing without the prior formation of a brazing alloy cladding on the surfaces to be brazed.

摘要： This invention relates to the bonding together of composite metalbodies by diffusion bonding whereby a bond of sufficient strength is obtained that the bonded bodies can be used to form mechanical structures, such as aircraft sub-assemblies. A metal body is discribed which is capable of being diffusion bonded to another metal body to form a mechanical structure characterised in that the body carries bonded thereto two superposed layers comprising an outer liquation layer and an inner buffer layer wherein the body is capable of being diffusion bonded to the other body via its liquation layer, and wherein the compositions of the body, the buffer layer and the liquation layer are selected such that under the conditions of diffusion bonding the constituents of the liquation layer will diffuse more readily into the buffer layer than into the body. Preferably the body is of an aluminium alloy, for example one that is superplastically deformable.

摘要： The invention provides an apparatus and process for continuous thermal hydrolysis of cyanide ions and cyanide-containing ions contained in a liquid. The liquid is passed through a reactor (12) equipped with a heater (28) and the liquid is reacted at a preselected temperature in the reactor (usually 150 to 250 °C). However, to minimize scale formation, which is a major problem, the liquid is partially heated prior to its introduction into the reactor (12) by means (16), such as steam injection through a venturi mixer, which avoid sharp temperature gradients but nevertheless produces rapid (preferably instantaneous) heating. The heating carried out in the reactor can then be reduced, preferably to less than 1.55 watts/cm2 of reactor wall, in order to minimize scale formation. The reactor (12) is also preferably orientated vertically to make scale build-up difficult and is of a narrow elongated shape to ensure that all of the liquid flows rapidly through the reactor while providing a suitable retention time for complete hydrolysis. The liquid may then pass to a settling tank (36) for removal of scale and solid particles.

摘要： A process is described for removing dissolved silica from process solutions or slurries formed in the Bayer process for producing alumina from bauxite. In the novel process, a Bayer process solution or slurry is contacted with porous agglomerates of a material containing Bayer process desilication product and bonded together by a polymer resin which is resistant to chemical degradation by high concentrations of caustic present in Bayer process liquors. The desilication product is essentially complex hydrated sodium aluminum silicates and typical bonding resins are polyvinylchloride or polypropylene.

摘要： A process for producing particles of magnesium spinel (magnesium aluminate) suitable for reinforcing metal matrix composites. The process involves mixing a waste material containing alumina or a precursor, such as dross residue, ESP dust or offgrade or contaminated alumina from Bayer process plants or molten salt electrolysis factories, with magnesium oxide or a precursor to produce a mixture, calcining the mixture at a temperature suitable to produce magnesium spinel (usually between 1450 and 1650 DEG C), and collecting particles of the magnesium spinel having a size in the range of 5-50 mu m, if necessary after comminuting larger particles to sizes in the desired range. Preferably, particle growth promoters may be added to the starting materials, examples being metal oxides and fluorides generally used in amounts of about 1-2 % by weight. The resulting inexpensive particles have a size suitable for metal matrix reinforcement and are substantially unreactive with molten aluminum and aluminum alloys.

摘要： The invention relates to a process for producing colour change devices incorporating latent indicia and colour change devices incorporating latent indicia produced by the process. The process involves anodizing a colour generating metal (11), having limited surface areas thereof covered by a mask (12), in the presence of an adhesion-reducing agent in order to produce a colour-generating laminate incorporating an anodic film (13) having detachable and non-detachable areas (b, a). The improvement of the invention involves forming the mask (12) from a masking material which permits anodization of areas of the surface covered by the mask while preventing the adhesion-reducing agent from exerting a substantial adhesion-reducing effect in the areas of the surface covered by the mask. The anodic film having the detachable and non-detachable areas (b, a) can then be formed by means of a single anodization step carried out in the presence of the adhesion-reducing agent. It is therefore unnecessary to employ two partial anodization steps as in the past, which simplifies the fabrication procedure and makes the procedure less expensive.
