Patent GB-992194-A (GB)
Title: The production of perfluoro- and perchlorofluoro-acetones
Filed: 1963-09-25
Abstract: Perhaloacetones of the formula C3OCl6-xFx where x is 1 to 6 are made by heating in the vapour phase one or more perhalogenated acetone containing 0 to 5 fluorine atoms and no halogens other than chlorine and fluorine with substantially anhydrous hydrogen fluoride in the presence of a catalyst consisting of chromium trifluoride at a temperature high enough to cause fluorination of the perhaloacetone to give a product of higher fluorine content. Preferably the reactants are heated to a temperature of 250-550 DEG  C., and the hydrogen fluoride is used in an amount not more than 25% in excess of that theoretically required for perfluorination. For the production of pentafluorochloroacetone and hexafluoroacetone, the preferred starting materials are perhalogenated acetones containing 0-4 fluorine atoms. The catalysts may be unsupported, or supported on an inert carrier, such as calcium, which is stable at the reaction temperature and resistant to hydrogen fluoride and chloride. Detailed examples are given. Specification 794,075 is referred to.ALSO:A catalyst (for making fluorine-containing perhaloacetones by heating a perhaloacetone in the vapour phase with hydrogen fluoride) consists of chromium trifluoride in unsupported form, or supported on a suitable inert carrier, such as calcium fluoride.  The catalyst may be made by pelleting chromium trichloride to 3-14 mesh size and treating with anhydrous HF at 350-600  DEG C.  Alternatively the chromium trichloride may be reacted with liquid anhydrous HF in a polar solvent and the product heated to remove unreacted and by-product hydrogen halides.

Title: Process for the preparation of coloured vegetable powders
Inventor: AUDIBERT GEORGES
IPC: B64D37/20
Filed: 1960-11-04
Abstract: The production of coloured powders from raw vegetable materials entails adding Saccharomyces cerevisiae to ferment sugar in the juice and intensify the natural colour of the juice, halting the fermentation by heating, producing the desired colour intensity by an addition of dextrose, levulose or lactose which has been sterilized by heat, and drying the resulting liquid, preferably by atomization. The juice may first be subjected to heating to destroy enzymes and sterilize it.  After the fermentation and before the sugar addition, the juice may be clarified by centrifuging.  According to an example, washed beetroots are pulped to liberate juice, the juice is fermented with baker's yeast, whereupon the red colouring, normally suppressed by the sugar of the beetroot, is intensified, fermentation is arrested by heating at above 60 DEG C., the desired amount of sterilized sugar is added, and the juice is dried to a powder.

A hollow charge projectile, or hollow charge, has a plastics lining which may have a tapered wall-thickness, and is characterized in that the lining material has embedded in it, threads, tissues or textures, 2, of glass-fibre. The lining 1 may be bottle-shaped, semispherical or other similar geometrical shape and may be formed of plastics with the precision necessary to achieve consistent results, e.g. the lining 1 may be a polyester with glass-fibre reinforcements 2. The specific weight of the lining may be increased by the addition to the lining material of powdered heavy metals, or non-metals such as barium sulphate. The powdered metal may be magnesium as an aid to combustion. The detrimental effect of a projectile's rotation upon the hollow charge performance may be compensated by using a liner 6 reinforced by glass fibres as shown in Fig. 4, in which the stepped shape imparts a tangential component of motion to the hollow charge in opposition to that of the projectile. Reference has been directed by the Comptroller to Specification 924,467.
