Abstract: 569,045. Magnesium chloride. FAIWEATHER, H. G. C. (Mathieson Alkali Works). Nov. 3, 1942, No. 15512. Drawings to Specification. [Class 1 (iii)] In the production of magnesium chloride from calcined dolomite and a, brine containing calcium and sodium chlorides such as waste liquor from the ammonia soda process, the mixed oxides from the calcination are added to a brine containing 8-18 per cent of CaCl2 in such quantity that 0.85 to 1.2 mols of MgO are added per mol. CaCl2, the mixture is treated with gases containing carbon dioxide, such as those resulting from calcination of the dolomite, at 60-85‹ C., and after separation of the precipitated calcium carbonate, the solution is concentrated to precipitate sodium chloride which is removed, having a magnesium chloride solution which may be evaporated to obtain the dehydrate. If the brine used contains sulphates, the necessary amount of barium chloride to effect their removal may be added before the carbonation step. A flow sheet for the process is given and suitable apparatus described.

Abstract: 985,847. Discharging material from shaft furnaces; revolving grates. ALUMINIUM LABORATORIES Ltd. April 22, 1963 [May 8, 1962], No. 15697/63. Heading F4B. A rotary extractor 18 for removing material from a shaft furnace 10, Fig. 1, which may be a converter for the extraction of aluminium by the sub-halide process, comprises a substantially conical rotary member in which the sections taken in planes perpendicular to the control axis are substantially circular at the lower end and become progressively more oval at higher levels, tending to a straight line near the top of the extractor, Fig. 3. The top of the extractor may form a chisel edge 23 bisected by the central axis about which the extractor rotates. The surface of the extractor may have ridges 20, formed round the surface at different levels. Since the weight on the extractor is substantially symmetrically distributed about the axis, and the irregularities on the surface have no side edges, the wear of the extractor and its bearings is minimized.

Relates to a function generator for use in analogue computers wherein an output voltage approximating to a desired function of an input voltage is obtained by means including a plurality of component circuits each, as shown in Fig. 4, comprising a semi-conductor diode D which is biased in the reverse direction by a biasing voltage Uv applied thereto through a biasing resistance Rv and to which the input voltage Ux is also applied through a linearising resistance Ro, characterized in that a plurality of sem-conductor diodes Di-Dm is connected in the forward direction in series with the biasing resistance Rv, in each component circuit to maintain substantial constancy of production of the desired approximation to the said function despite temperature variations. The plurality of circuits are connected together at S, the combined signal thus appearing at this point being then applied to a feed-back amplifier, at the output of which the required approximate function appears. In the embodiment described the temperature compensating diodes have substantially the same characteristics as the diode D, and their number m is chosen such that the equation m = Ro+Rv/Ro is satisfied. Where possible the biasing and linearizing resistors Rv and Ro should be made equal so that the number of compensating diodes may be limited to two (Fig. 5, not shown).
