Title: Process for the production of practically alcohol-free beverages
IPC: C12G3/02
Filed: 1925-05-11
Abstract: 244,988. Meyer, J. F., and L³cker, H. May 11, 1925. Fermenting.-Comprises a process for the production of practically alcohol-free beers &c. in which an alcoholic fermentation of short duration and effected under pressure is interrupted by cooling, and subsequently clarifying the fermented liquor while still under pressure by the use of centrifuges. The acidulation of beer wort required to cover the taste of sugar is entirely or mainly effected by controlling the malting and mashing, that is, for instance, by prolonging the duration of the malting process and increasing the temperature above the usual degree. The degree of acidity required to cover the taste of sugar is produced some time prior to the short alcoholic fermentation. The clarification may be effected in two or more stages, the first stage effecting the removal of the yeast, and the second stage the final clarification.

Abstract: 316,542. Sachtleben Akt.-Ges. f³r Bergbau und Chemische Industrie. July 30, 1928, [Convention date]. Barium sulphate.-Natural heavy spar is calcined under reducing conditions at 1300-1350‹ C., quenched in water, and freed from the sulphides formed from the metal oxides present as impurities, as by washing followed by wet grinding and treatment with a small amount of a mineral acid such as sulphuric acid, A pure white product is obtained. In the case of spars containing bitumen, the latter establishes reducing conditions during calcination, which may then be effected with the spar in lumps, whilst spars free from bitumen may be ground and mixed with carbonaceous material prior to calcination. An alternative treatment comprises calcination under reducing or oxidizing conditions and quenching in a sulphide solution of for instance barium sulphide to form sulphides of the metals to be removed. Quartz present in the spar is also removed by the process of the invention.

Title: Improvements in and connected with Bombs and in Means for Projecting them.
Inventor: STONE ANDREW JACKSON
IPC: F42B12/20
Filed: 1916-09-04
Abstract: 125,605. Stone, A. J., and Shuker, W. Sept. 4, 1916. Ordnance design; riflings.-Relates to guns of the kind in which the explosion of the propellant cartridge drives a projectile in one direction and drives an inertia mass in the opposite direction, so as practically to annul recoil, for example as described in Specification 23512/11. According to the invention, the barrel 9 for the inertia mass 11 is of considerably smaller diameter than the barrel 4 for the main projectile 1, the friction of the inertia mass in its 'barrel being, however, made greater than the friction of the projectile in its barrel; this is obtained by making the rifling of the main barrel 4 steeper than that of the small barrel 9. The projectile 1 is attached by spring catches 5 to a plate 2 adapted to fit the rifling of the main barrel 4 and provided with a stem 8 fitting into the small barrel, the propellant cartridge 1<a> being situated between this stem and the inertia mass 11. When the cartridge is fired, spring plugs 6 set back, releasing the spring catches 5, which in turn disconnect the projectile from the plate 2. The gases of explosion act first on the stem 8, and when the stem 8 has passed into the large barrel, the gases act on the plate 2 as well. The projectile is also provided with wings which swing out when no longer confined by the barrel 4.

Abstract: The invention comprises 18-norhydrocortisone and its esters having the formula: <FORM:0952491/C2/1> where R represents hydrogen or an acyl radical derived from an organic carboxylic acid having 1-18 carbon atoms and a process for the preparation thereof by subjecting 11b , 17a -dihydroxy-13Hb  -18- norpregn -4- ene-3, 20-dione to the action of an active culture of Colletotrichum lindemuthianum so as to form 18-norhydrocortisone, which if desired may be converted into an ester of 18-norhydrocortisone by esterification with the corresponding acylating agent. Alternatively 11b , 11a -dihydroxy 13Hb -18-norpregn -4- ene -3, 20-dione is iodinated to yield 11b , 17a  - dihydroxy -21- diiodo -13Hb -18- norpregn -4- ene-3, 20-dione, which is acyloxylated so as to form an ester of 18-norhydrocortisone, which if desired may be converted into 18-norhydrocortisone by saponification. The starting 11b , 17a -dihydroxy -13Hb  - norpregn -4- ene -3, 20-dione may be obtained by forming the 3, 20 semicarbazone of 17a -hydroxy -18- nor-pregn -4-ene -3, 11, 20-trione, reducing the 11-keto group thereof e.g. with an alkali metal borohydride and liberating the ketone groups at 3 and 20 positions e.g. with pyruvic acid.

Abstract: 1,261,928. Treating reaction mixtures containing hydroperoxides. SUMITOMO CHEMICAL CO. Ltd. 10 March, 1969 [14 March, 1968], No. 12601/69. Heading C2C. A process for treating an alkaryl tertiary hydroperoxide containing mixture obtained by contacting at least one secondary alkyl aromatic hydrocarbon with molecular oxygen or a molecular oxygen-containing gas in the presence of an alkaline material as stabilizer comprises removing substances insoluble in the hydroperoxide-containing mixture by filtration and removing any aqueous phase present and subsequently treating the hydroperoxide-containing product with an aqueous solution of an inorganic alkaline compound other than a hydroxide of an alkali metal, at a temperature from 0 to 100C. to give an aqueous phase free from hydroperoxide and an organic phase which contains the hydroperoxide and which is substantially free from corrosive acids. The treated hydroperoxide containing mixture is subjected to an acid-catalysed cleavage reaction to convert the hydroperoxide into an aromatic hydroxy compound and an aliphatic ketone. In examples hydroperoxides obtained by oxidation of cumene and cymene isomers are treated by the process and subjected to acid cleavage. The treatment is shown to reduce corrosion of mild steel by the phenol-containing fraction remaining after distillation to remove acetone.

Abstract: 721,617. Electrically-tripped switches. BRITISH THOMSON-HOUSTON CO., Ltd. May 19, 1952 [May 18, 1951], No. 12606/52. Class 38 (5). Contacts 17, 18 are normally held closed by a latch 26 which may be moved downwards into releasing position either by bending downwards of a current-carrying bimetal strip 13 on overload or, on heavy overload, by the downward movement of a permanent magnet 33 which is normally attracted by an armature 32 surrounding the bimetal strip. With increasing overload either with D.C. or A.C. the flux circulating in the armature 32 due to the current in the bimetal. strip reaches saturation proportions, increasing the reluctance of the armature and so lessening the attraction between the armature and the magnet 33 so that the latter is eventually forced downwards by the spring 37 carrying with it the frame 30 and latch 26. Adjustment of the magnetic attraction and hence of point of release is effected by rotating the magnet 33 by means of the stem 38. Resetting of the switch is effected by hand-operation of a plunger 31.
