Title: Improvements in or relating to the production of artificial sausage casings, more particularly round sausage casings
IPC: B29C53/12
Filed: 1936-06-26
Abstract: <PICT:0458238/IV/1> Ring-shaped tubes of regenerated cellulose, particularly round sausage casings are prepared by subjecting a coiled tube which is still moist and in a blown out condition, to drying, firstly on the inner side of the coil and then all over.  The tube may, for example, be wound in the form of a helix on a grooved drying roller, and when the inner side has dried, be dried all over by means of hot air on the same or another roller.  Advantageously, the first drying on the inner side of the coil takes place in an atmosphere of relatively high moisture content and at a temperature of 100 DEG  C. and the final drying takes place at a lower temperature, e.g. 60 DEG  C.  The moist tube from the reel a passes between nip rollers b and spirally over the drying roller which is divided internally into two portions, the first c<1> being heated and the second c<2> unheated.  The roller is enclosed by a casing which also is divided into two portions, the first d<1> which encloses c<1> being supplied with moist air, and the second d<2> which encloses c<2>, with hot air. The coil, after blowing up with air, is passed between nip rollers e and wound up on f in such manner as to retain the ring or coil shape of the tube.  Conveniently, the tube is formed by extrusion from a nozzle shaped in such manner that one part of the wall is thicker than the others and this part is placed against the roller during drying.

Title: Improved manufacture of polyphosphates
IPC: C01B25/41
Filed: 1934-06-19
Abstract: Polyphosphates, especially alkali polyphosphates, are obtained by heating mixtures of mono- and di-orthophosphates or starting materials which form these compounds to temperatures above 300 DEG C. but below the fusion point of the polyphosphate produced, if desired after pre-calcination.  Mixtures of mono-and di-sodium phosphates, or of phosphoric acid or phosphorus pentoxide and disodium phosphate or sodium hydroxide or carbonate may for instance be used.  Calcium-containing sodium polyphosphates may be obtained by incorporating mono- or di-calcium phosphate or calcium carbonate in the reaction mixtures.  The initial mixtures may be dehydrated at a low temperature before the conversion into polyphosphate is effected. In examples relating to the production of the compounds Na5P3O10 and Na6P4O13\t temperatures of 450--500 DEG  C. are used, but in any particular case temperatures just below the sintering point of the product are preferably employed.  By heating under reduced pressure the temperatures used may be lowered.  According to the Provisional Specification, the salt Na3H3(PO4)2 may be used to produce the compound Na6P4O13; and temperatures may be used which cause the polyphosphates to fuse.

Abstract: 1,219,146. Reprocessing nuclear fuel. ATOMENERGI A.B. 18 April, 1968 [21 April, 1967], 18456/68. Heading G6R. Plutonium and uranium are recovered from a plurality of nuclear fuel elements which have been irradiated, e.g. in a fast reactor, to different levels, by extracting Pu with a selective solvent from a solution of the highly irradiated elements, combining the residual solution with a solution of the less irradiated elements, extracting U and Pu from this combined solution with a different solvent, and separating the Pu and U extracted. The highly irradiated elements may be dissolved in nitric acid and extracted with trilauryl amine or trilauryl methylamine, which is treated with acetic acid to re-extract the Pu. The residual aqueous phase is combined with a nitric acid solution of the less irradiated elements and extracted with tributyl phosphate, dibityl carbitol, diamyl butyl phosphonate, or dibutyl phenyl phosphonate. Pu is selectively extracted from the organic phase by contact with a reducing solution of U (IV) nitrate or Fe(II) sulphamate. Pu having different isotope contents may be obtained by recovery from the different solutions separately.

[Also in Division G1] A method of obtaining a firing signal for a weapon launcher fixed to a non stable platform consists in measuring the angle between an axis of the launcher and a fixed geographical axis and generating the signal at the point in time when movement of the platform causes the said angle to have a certain value. As shown, a detector F for measuring the angle α, Fig. 2, between the vertical and an axis of the launcher supplies a signal to a circuit 3 which may be an impedance-matching device or amplifier. The circuit 3 generates a voltage V 1 , Fig. 3, which is applied to a bi-stable trigger circuit 4 generating a voltage V 2  having a waveform 10, Fig. 4. The output V 2  is applied to a condenser 6 and rectifier 7 to generate a voltage V 3  having a waveform 11, Fig. 5, this voltage causing a mono-stable trigger circuit 5 to generate a voltage V 4  constituting the firing signal 12, Fig. 6. The rectifier 7 ensures that the voltage V 4  is produced only when the said angle is obtained by movement of the platform in a certain direction. This feature is desirable if the platform motion is asymmetric -and its movement in -the opposite direction is associated with unfavourable speeds and accelerations. The platform may be constituted by a ship, submarine, hovercraft, helicopter or other vehicle.
