Patent GB-621569-A (GB)
Title: Process for the manufacture of alkali aluminium fluoride
IPC: C01F7/54
Filed: 1946-05-01
Abstract: Alkali aluminium fluoride is produced by sintering or melting a charge of fluorspar or like fluoride, free or combined silica, and alkaline alkali metal compounds, e.g. soda, or mixture of materials capable of yielding such compounds, lixiviating the reaction product with an alkaline alkali metal aluminate solutoin to form an alkaline alkali metal-aluminium fluoride solution, and precipitating the double fluoride from the separated liquid by carbon dioxide or a bicarbonate.  An aluminate solution obtained by decomposing bauxite with soda or caustic soda, or a calcium aluminate slag with an alkaline solution may be suitably employed. In a modification, the alkali aluminate for use in the lixiviation step may be formed in the sinter or melt by adding aluminous material, e.g. labradorite, nepheline or albite to the furnace charge, in which case additional soda, limestone or lime must be added also.  These aluminous materials also furnish the silica required.  The supply of carbon dioxide is preferably such as to leave free alkali in the solution, which after separation of the double fluoride may be used for the leaching of more calcium aluminate slag.  When this is completed, the sludge from the preceding lixiviation of the fluorspar sinter is added to the liquid.  The sludge is thereupon filtered and an adjusted quantity of alkali fluorspar sinter is leached in the solution, the double fluoride being then precipitated as above.  When by continuance of these operations, the alkali concentration reaches 150 gr./1. Na2CO3, bicarbonate is precipitated by carbon dioxide. In the precipitation of the double fluoride, carbonation may alternatively be such as to convert the alkali wholly or in part to carbonate or bicarbonate.

Title: Process for effecting hydrocarbon isomerization reactions
IPC: C07C5/27
Filed: 1942-02-13
Abstract: Saturated hydrocarbons are isomerised by passing a stream of a carrying fluid in substantially liquid phase through a first contact zone containing a bulk supply of a Friedel-Crafts type catalyst so as to dissolve a portion of the catalyst while precluding any reaction, while maintaining a higher catalyst concentration in the first zone than in the effluent therefrom, and allowed the effluent to flow into a second contact zone wherein saturated hydrocarbon material is isomerised in presence of a Friedel-Crafts type catalyst, a continuous flow being maintained sufficient to maintain the isomerisation reaction in the second zone.  Solid packing material is used in the second zone.  The hydrocarbon itself may be used as carrying fluid and hydrogen chloride may be added between the first and second zone. The temperature may be regulated by adding part of the hydrocarbon between the first and second zones.  Sludge formed in the second zone is precluded from entering the first zone where a circulating process is used.  An example is given of the isomerisation of normal butane.  Pentane and hexane, or mixtures containing any of these compounds may be isomerised in the same way.

Filed: 1961-04-13
Abstract: 972,192. Irradiation capsules. COMMISSARIAT A L'ENERGIE ATOMIQUE. April 13, 1961 [April 13, 1960; Aug. 25, 1960], No. 13334/61. Heading H5R. An irradiation capsule comprises a tubular body adapted for insertion into a channel of a nuclear reactor, means for supporting axially within the body a sample to be investigated, and a sleeve surrounding the sample so as to form two concentric annular spaces, one between sleeve and sample and the other between the sleeve and the tubular body; these two spaces are in communication so that a gaseous filling can circulate therein; means for electrically heating the sample are also incorporated. In the form shown, the capsule comprises a hollow metal tube 1, within which is mounted upper and lower members 6, 10 of refractory material. These members are similarly shaped, having a flanged base portion on which stands a central peg 7, 13. The sample to be studied is supported between these pegs, and in Fig. 1 is a closed graphite tube 14. Also supported between members 6 and 10 is a sleeve 9 separated by an outer annular space from tube 1 and an inner annular space from tube 14. These annular spaces are connected by openings 11, 12 in sleeve 9. The graphite tube 14 has a bifilar winding 18 round it, so that it may be heated to any desired temperature, which can be measured by thermocouples 25, 26. A further thermocouple 33 is fixed to the outside of outer tube 1. After the device is assembled, with the sample in position, a cover 2 is welded to tube 1, the device evacuated, and filled with carbon dioxide. The whole device can then be inserted into a nuclear reactor, and subjected to neutron bombardment. In the modification of Fig. 4, a propeller 35 arranged below the-member 6, is rotated by the circulation of the gas in the device. At the tip of one propeller blade is a spot 40 of radio-active material, the radiation from which passes out of the device, through a hole 42 in a lead screen 41, to a detector 43. Thus the speed of revolution of the propeller, and hence the rate of circulation of the gas, can be measured. In a further modification the propeller is driven by an electric motor, so imparting forced circulation to the gas.
