摘要： Iron-based alloy composition containing special proportions of nickel, chromium, aluminum, copper and carbon provides good corrosion-resistance characteristics for service in caustic media, e.g., sodium hydroxide, chloride media, e.g., magnesium chloride, caustic-chloride media, e.g., sodium hydroxide-sodium chloride mixtures, and also when exposed to some acid media, e.g., nitric acid. Special utility particularly includes resistance to stress-corrosion-cracking in hot caustic and chloride media. Alloy has good workability for production of wrought products such as plate, bar and sheet and is also suitable for making corrosion-resistant castings and welded structures, e.g., chemical plant equipment.

摘要： Recovery, by thermal upgrading, of nickel values from nickeliferous lateritic ores containing a silicate fraction is improved by forming agglomerates of the ore, a reagent containing at least one member selected from the group consisting of alkali or alkaline earth metal compounds in a small but effective amount to increase nickel recovery from the silicate fraction and a liquid hydrocarbon in an amount between about 1 and 12%, based on the weight of the ore and heating a static, shallow bed of the agglomerates established on a moving bed to partially melt the agglomerates to reduce and coalesce the nickel values into easily recoverable ferronickel concentrate. The grade of the ferronickel concentrate can be increased by incorporating a sulfur-bearing material in the agglomerates.

摘要： A double-eccentric variable drive system is disclosed comprising a drive shaft, two eccentrics mounted on the drive shaft to be driven thereby, and means for varying the eccentricity of both of the eccentrics simultaneously. The means in question comprises a spindle having left-hand screw-threads on one end thereof and right-hand screw-threads on the other end thereof and an enlarged central portion rotatably mounted in the shaft but radially fixed relative thereto. The eccentrics each have a radial bore therethrough tapped to correspond with and receive the threads of the spindle, the bores being aligned on opposite sides of the shaft. Each eccentric has an axial bore larger than the diameter of the shaft in a direction parallel to the spindle to allow for movement of the eccentrics radially of the shaft. The arrangement is such that rotation of said spindle in one direction will simultaneously increase the eccentricity of both of the eccentrics relative to the shaft and rotation of the spindle in the other direction will simultaneously decrease the eccentricity of both of the eccentrics relative to the shaft. Preferably, the eccentrics each have a dovetail slide and a diametrically opposite dovetail, the dovetail of one eccentric slidably engaging in the dovetail slide of the other eccentric and vice versa, each dovetail having said radial bore passing therethrough. The system is particularly adapted for use in solvent extraction.
摘要翻译： 公开了一种双偏心可变驱动系统，其包括驱动轴，安装在驱动轴上的两个偏心件以由其驱动，以及用于同时改变两个偏心轮的偏心度的装置。 所涉及的装置包括其一端具有左旋螺纹的主轴和另一端的右旋螺纹，以及可旋转地安装在轴中但相对于其径向固定的扩大的中心部。 偏心件各自具有穿过螺纹以对应于和接收主轴的螺纹的径向孔，孔在轴的相对侧对准。 每个偏心轮具有比平行于心轴的方向大的轴的直径的轴向孔，以允许轴的径向偏心运动。 该装置使得所述主轴在一个方向上的旋转将同时增加两个偏心件相对于轴的偏心率，并且主轴在另一个方向上的旋转将同时降低两个偏心件相对于轴的偏心率。 优选地，偏心轮分别具有燕尾滑动件和径向相对的燕尾形，一个偏心件的燕尾形可滑动地接合在另一偏心件的燕尾形滑动件中，反之亦然，每个燕尾座具有穿过其中的径向孔。 该系统特别适用于溶剂萃取。

摘要： Sulfate solutions containing at least one valuable metal from the group: Fe, Ni and Co, particularly solutions resulting from the leaching of lateritic ores or concentrates, are treated to recover the valuable metal. The latter is precipitated by treating the solution with magnesium hydroxide. The resulting magnesium-containing solution is treated with lime under controlled conditions to precipitate relatively fine particles of magnesium hydroxide and relatively coarse particles of gypsum. The difference in particle size is relied on to separate the magnesium hydroxide (for recycling) from the gypsum (which is calcined to regenerate lime).

摘要： A process of slurry coating particularly adapted to coatings less than one mil thick wherein a basis metal is coated with particles of a second metal dispersed in a liquid containing alkali-stabilized silica sol as the predominate film forming ingredient. The coated basis metal is dried; the coating is sintered thereon and then is worked. Provided that the silica to metal ratio is within a special range, residual silica in the coating metal does not interfere with working.
