Title: A process for the preparation and manufacture of 6-methoxy-8-alkylene-diamino-quinoline
Filed: 1951-06-01
Abstract: 6 - Methoxy - 8 - (4 - amino - 1 - methylbutylamino) - quinoline (" primaquine ") and 6 - methoxy - 8 - (3 - amino - 1 - methylpropylamino)-quinoline are made by heating 1 : 4-dibromopentane or 1 : 3-dibromobutane with an alkali metal phthalimide in an organic nonhydroxylic solvent, reacting the resulting N-bromoalkyl-phthalimide with 6-methoxy-8-aminoquinoline and splitting off phthalic acid from the product by treatment with hydrazine hydrate.  The first step is preferably carried out in acetone with potassium phthalimide at 45-65 DEG  C.  Examples are given of the production of the two compounds, these being separated by precipitation as salts, e.g. the hydrochloride, semioxalate and diphosphate.  A by-product may be formed from 1 mol. of 6-methoxy-8-aminoquinoline and 2 mols of 4-bromo-1-phthalimidopentane.

Title: Automatic control for adjusting rolling mills
IPC: B21B31/24
Filed: 1960-04-13
Abstract: 942,128. Rolling. S. W. WHEELER. April 13, 1960, No. 13121/60. Heading B3M. In a strip-rolling mill a pair of power-operated screwdowns 120 make a coarse adjustment of the pass between the working rolls 106 and the fine adjustment is made by means rotatable relative to the screwdowns, and actuated independently thereof by low-inertia forcemultiplying means in turn actuated by doubleacting fluid pressure means. The main screwdown 120 is rotated through splines 122 and a worm-gear 121 by motors 129, the screwdown spindle 125 being supported during removal of the rolls by a spring 145. The force multiplying means of the fine adjustment comprises a nut 126 rotatable by a rack and sector gear 136, 135, the rack 135 being reciprocable by an hydraulic cylinder 138. During coarse adjustment the nut 126 is stationary the screwdown 120 rotating within it. During rolling, to keep the thickness of strip constant the compensating fine adjustment is automatically effected by reciprocation of the rack 136 in response to thickness error signals. The screwdown spindle then is held against rotation by the splines 122 but is moved axially by rotation of the nut 126 according to the movements of the rack. The extent of adjustment is limited by stops 147. The lower rolls may be similarly adjusted by a rack 118 operated by a cylinder 158 and engaging a segment 117 attached to a screw-spindle 116 which engages a fixed nut 115. The strip thickness may be measured by X-ray methods or by a contact gauge and the error signal used to operate a pivoted jet, which impinges on a distributer block controlling the valves of the double-acting cylinders 138. The working rolls are urged apart by springs in casings 111 (not shown).

Title: Process for the production of sulphuric acid from sulphur-dioxide-containing-gases
IPC: C01B17/82
Filed: 1925-05-21
Abstract: 253,344. Metal Traders Technical, Ltd., (Metallbank und Metallurgische Ges. Akt.-Ges.). May 21, 1925. Sulphuric acid. - Gases containing sulphur dioxide are charged with the maximum quantity of nitrogen oxides by intimately mixing them with sulphuric acid containing nitrogen oxygen compounds, and the sulphuric acid which is produced in the gases is precipitated free or substantially free from nitrogen oxides by means of an electrostatic field. The residual gases are allowed to react further if necessary and the remaining sulphur dioxide is rapidly worked up owing to the quantity of nitrogen oxides present. The sulphuric acid is again separated free from nitrogen oxides by means of an electrostatic field. In a modification, 'the sulphuric acid is precipitated by means of a device for effecting intimate mixing of gases and liquids such as that described in Specification 149,647, [Class 55 (ii), Gas manufacture &c.], but in this case in order to prevent condensation of nitrogen oxides the acid is not allowed to rise above 54‹ B. and increased temperatures may have to be employed. In a further modification, gases containing sulphur dioxide are strongly charged with nitrogen oxides, for example by means of nitrosyl sulphuric acid of 58‹ B. as described in Specification 149,648 and are then treated with water in a reaction chamber or tower in regulated quanti. ties to prevent the concentration of the condensed acid from rising above 54‹ B. Preferably the gases and acid liquor pass down the tower. which may be packed or empty in the same direction so that the gas is in contact with the more dilute acid for most of the time. The water may be added in the form of a spray or as steam or as dilute acid. Specification 187,016 also is referred to.

Abstract: 1,159,775. Forming glass fibres. PPG INDUSTRIES Inc. 20 March, 1968 [4 April, 1967], No. 134:14/68. Heading C1M. An apparatus for forming continuous glass filaments by drawing glass from a bushing through a fibre forming zone, over a binder applicator, a gathering shoe and on to a winder, comprises a shield 40 made of an air impervious material, the major surfaces of which are angularly oriented to the horizontal, and which is located between the bushing and the applicator, the shield having a central opening 42 for the passage of the fibres 20. The shield may be arcuate in the form of a shallow U- shape, or may be of inverted V-shape (Fig. 2, not shown). A preferred apparatus has a plurality of fibre forming positions, each position being divided from the next adjacent one by a gas impervious divider and each position having its own shield 40. Suitable material for the shield 40 is galvanized or stainless steel. The shield prevents any upward flow of air, caused by the pumping action of the winder, into the fibre forming zone, thus reducing atmospheric fluctuations in the drawing zone and improving the stability of the fibre forming process.

Title: Improved manufacture of antirachitic substances
Filed: 1929-05-02
Abstract: 314,942. Steenbock, H. July 5, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Vitamins ;albuminoids ; esters.-Antirachitic substances are obtained by subjecting unsaponifiable lipoids, or their derivatives which may or may not be saponiflable, to the action of ultraviolet light. The derivatives may be prepared by combining unsaponifiable lipoids with compounds such as fatty acids or carbohydrates in known manner; or naturally occurring unsaponifiable lipoids and their derivatives may be separated from substances such as lanolin, from animal tissues such as brains, or from plant materials such as yeast, moulds, mushrooms, ergot, seeds, and straw, activation in such cases being effected either before or after separation from the parent substance. The separation may be carried out by extracting the starting material with a suitable solvent, such as alcohol, acetone, ether, pyridine, or volatile petroleum hydrocarbons, further treating the residue with acids, alkalis, or enzymes to hydrolyse the insoluble derivatives, and again extracting with a suitable solvent. 'The extracts may be purified, if desired, by a further saponification and extraction, the solvents being subsequently evaporated and the concentrates united. In an alternative process, the starting materials are saponified to break down the insoluble lipoid derivatives before extraction. Any suitable source of ultra-violet light, such as a quartz mercury vapour lamp, or a carbon arc, may be employed for activation, and the substances may be treated in the solid form or in solution. Radiation in the wave-length range from 230 to 315 ÁÁ is stated to be particularly effective. In an example, the crude lipoid fraction extracted with acetone from dried brain is saponified with alcoholic potash, diluted with water, and extracted with ether. The extract is evaporated, and the sterol contained in the residue is purified by repeated recrystallizations from alcohol, and by boiling with alcohol. From the white waxy crystals so obtained sterol acetate may be prepared by the action of acetic anhydride, and activated by exposure to ultra-violet light. Sterol acetate, stearate, palmitate, and benzoate, obtained by the action of the corresponding acid chlorides on sterols derived from brain, ergot, and yeast, may be similarly activated. Ergosterol, which may be extracted from plant material with pyridine, may also be combined with fatty acids or carbohydrates, and the resulting compound activated. Specification 236,197 is referred to.
