Patent GB-582579-A (GB)
Title: Improvements relating to the production or refining of aluminium
IPC: C22B21/00
Filed: 1944-04-19
Abstract: A process for producing or refining aluminium comprises reacting heated aluminium-bearing materials with a halide brought to the vapour-phase previous to the reaction, for instance a low-boiling or subliming halide such as aluminium chloride.  The aluminium volatilises under the formation of aluminium-halogen compound vapours from which the aluminium is recovered.  The aluminium may be brought into reaction in a finely-divided condition, e.g., powder or drops. The halide vapour should not be saturated under the condition of reaction.  This may be effected by employing a temperature of reaction higher than the temperature of evaporation of the halide. The reaction may be carried out under reduced pressure and/or in the presence of hydrogen or other gas inert to aluminium.  At least two halide condensers may be used and employed alternately as condenser and evaporator whereby the same amount of halide is repeatedly used for reaction without discontinuing the distillation.  If the temperature of the zone in which the aluminium is condensed is kept between the condensation temperature of aluminium and that of the halide, the halide is kept in the vapour phase in the reaction chamber or in circulation through it.  The halide may be condensed separately from the aluminium, and the heat of condensation of the aluminium may be utilised to evaporate and/or preheat halide required for further reaction.

Title: Improved process for the production of a sugar preparation from starch, and for manufacturing a milk suitable for infants
IPC: C13K7/00
Filed: 1934-03-07
Abstract: Starch is treated with enzymes, such as are obtained from Aspergillus especially Aspergillus Oryzae, or pancreatic anylase, which degrade it in the a  direction, the treatment being interrupted at a point at which the sugar product obtained consists of a -maltose and a dextrin body loosened up in the a  direction.  In an example, potato starch or starch from wheat, oats or other cereals is suspended in water and citric acid is added to give a pH of 5.  Ferments from Aspergillus Oryzae are added and the mixture is introduced into a boiler containing water at 65 DEG  C.  The breaking down of the starch is allowed to take place at this temperature until equal amounts of the dextrin and a -maltose are present, and the enzyme is then destroyed by heating to 80 DEG  C.  The solution obtained is filtered, concentrated to a viscous mass at a low temperature in vacuum, and dried further in vacuum giving a brittle product which is then ground finely.  The preparation may be added, after heating to destroy the enzymes but before evaporating, to fresh or partially evaporated milk and the mixture evaporated to give a dried milk preparation particularly suitable for infants.  Pectin or like protective colloids may be added to the sugar solution or the milk before or during the combination of these materials; thus a jelly may be prepared from the sugar solution and the pectin and added to the partially evaporated milk.

Title: Improvements in the manufacture of magnesium chloride
IPC: C01F5/30
Filed: 1946-03-11
Abstract: Magnesium chloride solution is prepared by distributing hydrochloric acid solution rapidly throughout a slurry of calcium carbonate and magnesium hydroxide, as by spraying whilst the slurry is in rapid motion, to cause selective conversion of the magnesium hydroxide whilst the calcium carbonate is un-reacted, and mechanically removing the suspended solids.  The slurry is preferably prepared by partially carbonating a slurry of magnesium and calcium hydroxides obtained by slaking dolomite calcined at 1600-1800 DEG  F.  Preferably, a slight excess of carbon dioxide is used to form magnesium carbonate, a small quantity of the hydroxide slurry being then added to reconvert the magnesium carbonate; some of the water is then advantageously removed and the cake repulped with magnesium chloride from an earlier stage whereby a more concentrated solution is finally obtained.  Solid magnesium chloride may be produced by spray drying, and magnesium therefrom by electrolysis.  Chlorine evolved may be converted to hydrochloric acid for use in the process.
