Abstract: A method of treating an organic material such as textile fibres with an alkali metal hydroxide solution including the steps of:   (i) contacting the organic material with the hydroxide solution to produce an effluent comprising an alkali metal hydroxide solution which contains multivalent ions and soluble and insoluble organic and inorganic matter; (ii) reducing the pH of the effluent to a value in the range 7 to 9 by contacting with an acid gas; (iii) filtering the solution from step (ii) to remove suspended insoluble matter having a size greater than 0,1 microns. (iv) filtering the filtrate from step (iii) to remove multivalent ions and organic matter having a molecular mass greater than about 300 daltons; (v) providing an electrochemical cell in which an anode compartment is separated from a cathode compartment by a cation selective membrane; (vi) passing the filtrate from step (iv) into the anode compartment of the electrochemical cell; (vii) passing an electrical current through the cell causing alkali metal ions to pass through the cation selective membrane and alkali metal hydroxide to be produced in the cathode compartment and the acid gas to be produced in the anode compartment;   (viii) returning the alkali metal hydroxide to step (i); and (ix) using the acid gas produced in the cathode compartment for reducing the pH of the effluent in step (ii).

Title: Process for the continuous preparation of acetates
IPC: C07C67/03
Filed: 1988-02-18
Granted: 1991-08-28
Abstract: The invention relates to a process for the continuous preparation of acetates by a transesterification reaction in the homogeneous liquid phase in the presence of a catalyst selected from metallic alcoholates. The process comprises more particularly the introduction of the catalyst into a reactor (R) and the introduction of the reagents, formed by an acetate (I) and an alcohol (II), into a distillation column (D1) surmounting the reactor (R) and operating at a pressure (P1) identical with that in (R). The acetate (III) formed is withdrawn from (R) mixed with the catalyst, which is separated and recycled in (R). An azeotropic mixture (M1), comprising the acetate (I) and the alcohol (IV) formed, emergences at the head of (D1) and feeds a distillation column (D2) at a pressure (P2) lower than (P1), so as to produce at the head of the column an azeotropic mixture (M2) depleted in alcohol (IV), the mixture being recycled in (D1). The process permits the use of relatively humid reagents and alcohols of low reactivity, more particularly secondary alcohols.

Title: Liner for a warhead
IPC: F42B1/02
Filed: 1988-03-05
Granted: 1992-04-22
Abstract: In known warhead liners (14), projectiles (15) with extremely flattened noses are produced as a result of explosion deformation. In consequence, the speed of such projectiles (15) is drastically reduced and the target speed is generally too low. To diminish the reduction in speed, the lining (20) has, inside a predetermined area (22) around the centre of the lining, a deeper indentation in the direction of the explosive (13) required for the explosion deformation than outside but in the immediate vicinity of this area (22). This measure makes it possible to achieve a projectile (30) with an ogival nose of smaller diameter.
