摘要： A process for producing articles comprising anodized films exhibiting areas of different colour and the articles thus produced. The process comprises anodizing a surface (16) of an article made of or coated with aluminum or anodizable aluminum alloys to produce an anodic film (11) having a porous outer layer and a non-porous inner barrier layer (15) between the porous layer and the underlying surface (16) of the metal article. A metal is electrodeposited into the pores (12) of the film to form a semi-reflective layer (18) of metal deposits (17) in the film (11) which generates a visible colour by effects including light interference between light reflected from the semi-reflective layer (18) and light reflected from the underlying metal layer (10). A cathodically biased electrode (20) is brought into contact with or close proximity to limited areas (A) of the film (11) to cause the barrier layer (15) to thicken in those limited areas only. This step in itself may create a pattern of different colours in the contacted and non-contacted areas of the film (11). However, further anodization of the surface is preferably carried out before, after, or both before and after, the contact with the electrode (20), at a voltage which causes the film (11) to thicken below the deposits in the non-contacted areas (B), but not significantly in the contacted areas (A). If desired, the film (11) can be detached from the aluminum article (10) on which it was formed and a very thin layer (23) of metal applied to the exposed surface (22) of the film in order to make a very thin, flexible, planar, patterned article suitable for use as a packaging sheet, or the like.

摘要： A process for producing unsintered agglomerates from dust originating from a product stream of an industrial process involving thermal treatment of materials containing alumina such that the agglomerates are suitable for handling and return to the product stream or an industrial feed stream, and the agglomerates so formed. The process involves binding the dust particles together using rehydratable alumina and water as a binder. If the dust already contains rehydratable alumina (e.g. dust from alumina and bauxite calciners), further rehydratable alumina need not necessarily be added. If the dust contains little or no alumina, a source of rehydratable alumina sould be added to the dust. If the dust contains an alumina hydrate, some or all of the dust may be heated to form rehydratable alumina. The dust and/or added rehydratable alumina may be ground, if desired, to create fresh surfaces and a range of sizes suitable for compaction. In all cases, the resulting solids should have a ratio of dust to rehydratable alumina of 0.5 - 5 : 1 by weight. After mixing the solids with water (usually 2 to 40 parts, more preferably 10 to 35 parts, by weight per 100 parts by weight of solids), the resulting mixture is agglomerated and the agglomerates are preferably aged for up to 24 hours in an atmosphere of high relative humidity in order to strengthen the agglomerates. Optionally, drying and calcining (without sintering) may then be carried out. The resulting dust agglomerates can be handled without significant fracturing or dust generation and can, if desired, be returned to the product stream or to an industrial feed stream.

摘要： A method of heating a workpiece or workpiece assembly, and a load assembly suitable for heating by the method. The method involves heating the workpiece or workpiece assembly in a microwave cavity surrounded by one or more rings made of electrically conductive material. The rings fix the electrical field in such a way that uniform heating of the workpiece or workpiece assembly can be achieved. Large workpieces or assemblies can be heated and, if sinterable, sintered in this way without the problems normally caused by lack of uniform fields when microwaves are used to heat large loads.

摘要： A method of producing platelets of refractory metal borides and the platelets so-produced. The method involves reacting an oxide of a refractory metal or a precursor thereof and B2O3 or a precursor thereof with carbon or a carbon precursor in the presence of a small amount of an alkali metal oxide, such as sodium oxide or potassium oxide, or a precursor. The reaction should take place under an atmosphere of an inert (non-reactive) gas. The alkali metal oxide allows the reaction temperature to be brought below 1800 °C, which reduces impurities in the product, and affects the shape of the particulate boride product, resulting in the formation of platelets. The carbon used in the reaction is preferably derived from calcined anthracite coal or petroleum coke because such carbon sources permit the reaction to be carried out at lower temperatures. The platelets of the refractory metal borides so-produced can be used as reinforcements for ceramic or metal matrix composites or for other purposes.

摘要： The invention relates to busbar arrangements for aluminum alectrolytic cells. In a first aspect, the invention provides at least one generally horizontal collector busbar (15A-15D, 16A-16D) on each side of the cell and a number of current tapping points (18A-18D, 19A-19D) along each collector busbar so that current flows along the collector busbar in opposite directions on each side of the taps. This produces changes of sign in the vertical component of the magnetic field acting on the pad in the longitudinal direction and helps to prevent pad instabilities. In a second aspect, the current taps for the collector busbars (18A-18D, 19A-19D) are vertically disposed so as to convey current well below the level of the metal pad (17) so that adverse magnetic effects caused by further distribution of the current are minimized. In a third aspect, when the cells are arranged in a row, current is conveyed between cells in a round-end under-cell crisscross arrangement with long horizontal runs (29A, 27B') of the busbars of adjacent cells being positioned close together with currents flowing in opposite directions to counteract adverse magnetic effects.
摘要翻译：本发明涉及铝电解池的母线装置。在第一方面，本发明在单元的每一侧提供至少一个大体上水平的收集器汇流条（15A-15D，16A-16D）和沿着每个收集器汇流条的多个电流出口点（18A-18D，19A-19D）使得电流沿着集电母线在水龙头的每一侧沿相反方向流动。这产生在纵向上作用在焊盘上的磁场的垂直分量中的符号变化并且有助于防止焊盘不稳定性。在第二方面，用于收集器母线（18A-18D，19A-19D）的电流抽头被垂直地布置，以便将电流输送到金属焊盘（17）的电平以下，从而使电流进一步分配电流最小化。在第三方面，当电池被排列成一排时，电流在圆形细胞内十字交错布置的细胞之间传送，相邻电池的母线的长水平行（29A，27B'）与电流沿相反方向流动以抵消不利的磁效应。

摘要： Coolant containment apparatus for a rolling mill in which aqueous coolant liquid is sprayed onto the upper and lower work roll (11, 12 respectively) surfaces by upper and lower spray heads (24, 28 respectively) only on the exit side of the mill, including an enclosure (32) maintained at subatmospheric pressure and surrounding the upper spray head (24) and adjacent upper work roll (11) and backup rool (10) surfaces, upper and lower air dam members (40, 42 respectively) extending along the edges of the enclosure (32) above and below the spray head to define narrow air gaps at the roll surfaces, slippers (44) connected to ends of the dam members and in rubbing contact with the rolls to maintain the gap widths constant, and seal members (48) mounted on the roll supports (15) at the ends of the mill and cooperating with the enclosure to confine the enclosure interior. A wiper (50) removes coolant liquid from the upper work roll on the entry side of the mill, while collectors (52) catch and remove coolant spraying through the ends of the roll bite (18) at the exit side of the mill, and air is blown into the roll bite on the exit side to move coolant liquid from the surface of an emerging rolled metal strip (20) into the collectors. Below the mill pass line, a shield (58) protects the rolled metal strip from coolant from the lower spray head (28).

摘要： The invention relates to a process and a device for casting metal rods or the like in bag casting using an ingot mould (1) which sinks into a liquid bath (5) as it is being filled with the casting metal. The ingot mould pipe (1) is filled with casting metal through a filling pipe (11). The lower end of the filling pipe, which is lowered in advance into the ingot mould pipe, has an outlet opening (12). The ingot mould pipe is suspended with its lower end at approximately the same level as the liquid bath (5) or above until this introduction is almost complete. The casting metal is allowed to flow through the outlet opening (12) of the filling pipe (11) into the ingot mould pipe (1). Simultaneously, the ingot mould pipe is lowered into the liquid bath (5) at a speed which bears a predetermined ratio to the speed at which the casting metal rises in the mould pipe (1).
