Title: Production of 6-demethyltetracyclines
IPC: A61K31/65
Filed: 1964-11-04
Abstract: 6-Demethyltetracycline antibiotics, e.g. 6-demethyl chlortetracycline are produced by culturing a tetracycline-antibiotic-producing strain of a species of the genus Streptomyces in a nutrient medium containing assimilable carbon and nitrogen sources, a methylation inhibitor being added to the fermentation medium gradually so that the ratio of the amount of nucleic acids and proteins formed related to that of the inhibitor added is maintained substantially constant during the course of the fermentation.  The methylation inhibitor may be a compound of general formula <FORM:1091046/C2/1> where R is a substituted or unsubstituted guanidine, thiazole, pyrimidine or pyrazine radical, e.g. p-aminobenzene sulphonyl guanidine, 2 - (p - aminobenzene sulphonyl) - 4,6-dimethyl pyrimidine, 2-(p-aminobenzene sulphonyl) - 6 - methoxy - pyridazine and 2 - (p-aminobenzene sulphonyl) - 4 - methyl - thiazole. For the production of 6-dimethyl chlorotetracycline or 6-demethylbromotetracycline, the fermentation medium contains chloride or bromide ions respectively in an amount greater than 50g /ml.  If 6-demethyltetracycline is desired, the fermentation medium should contain less than 50 g /ml. of chloride or bromide ions and/or contain chlorination or bromination inhibitors. Preferably, the whole of the methylation inhibitor is added during the first 24 hours of fermentation.

Title: Photographic shutters
IPC: G03B9/20
Filed: 1929-07-05
Abstract: 315,707. Barenyi, A. July 16, 1928. [Convention date]. Shutters with pivoting blades.-In a shutter comprising multiple pivoted blades 2, which are rotatable for opening and closing the lens aperture by a driving ring, the movement of the ring is controlled by a pair of pawls and mechanism for moving one pawl out of engagement with the ring, for allowing the other pawl temporarily to arrest the ring whilst the first pawl becomes positioned for re-engagement with the ring, and for moving the second pawl to the releasing position. In one form three crescent shaped blades 2 are mounted on pinions 4 which are pivoted at 3 to a plate 19. An internal gear wheel 5 in mesh with the three pinions 4 has circumferential recesses 6 adapted to be engaged by pawls 7 which are mounted on a ring 8 disposed concentrically above the gear wheel 5. The ring 8 is caused to rotate in an anticlockwise, direction against the tension of springs 9 by operation of the toothed segment 11 through the shutter setting lever 12, the pawls 7 slipping over the raised parts 13 into the next recesses 6 in the gear wheel 5 which is prevented from rotating with the ring 8 by a pawl 14. The springs 9 are kept under tension by the engagement of pawls 15 and 16 in the recesses 6. To make an exposure the lever 25 is depressed and a lug 23 first lifts the pawl 15 allowing the gear wheel 5 to rotate through the slight clearance 27. The lug 23 then releases the pawl 15 which then presses on the portion 13 and a further motion of the lever 25 causes a further lug 24 to raise the pawl 16, leaving the gear wheel 5 and ring 8 free to rotate until the pawl 15 engages the next recess 6, a curve 30 being provided in the recesses 6 to prevent, jarring. The teeth on the pinions 4 are chosen so that this movement of the gear wheel 5 causes the blades 2 to make a complete rotation, thus opening and closing the lens aperture. In a modification, the springs 9 are replaced by spring-controlled toothed wheels adapted to engage teeth on the ring 8 and the pawls 15 and 16 are mounted on a single pivot and operated successively by a single lug on the lever 25.

Abstract: 994,456. Storing containers on a rollerway conveyer. BRITISH BOOT SHOE & ALLIED TRADES RESEARCH ASSOCIATION. June 13, 1961 [June 13, 1960], No. 20701/60. Heading B8A. Containers 10 roll down rollerway 1 on rollers 2 mounted thereon, and are transferred to rollerway 5 by means of switch 7, and rest on rollerway 5 against stop bar 19 ready for discharge. Switch 7 carries rollers and is pivoted at 8 and counterweighted at 9 and its movement is controlled by dash-pot 20. Two stops 15 and 16 control the movement of a container moving from rollerway 1 on to switch 7. Operation.-When a container is discharged at 19 the containers on rollerway 5 move down the rollerway and the container resting on switch 7 also moves down to release the switch which under the bias of counterweight 9 pivots upwards and as it does so engages stop 15 to rotate it counterclockwise. This releases the container held by stop 15 and this container moves on to switch 7 and causes it to pivot downwards into the position shown. At the same time stop 16 is released, i.e. by the last container which lies on arm 18 of the stop, and pivots anti-clockwise to release a container which moves into the position shown held by stop 15.

Title: Improvements in process of producing rayon
IPC: D01F2/10
Filed: 1947-07-31
Abstract: In order to counteract the tendency for deposits to form on the spinneret and eventually to block the orifices, a small proportion, e.g. 0.0001 to 0.05 per cent of a polymerized alkylene oxide is dissolved in a viscose spinning solution or in the coagulating bath. The alkylene oxide preferably has a degree of polymerization exceeding 30.  Polymers of ethylene oxide or homologues of ethylene oxide containing alkyl, cycloalkyl, or aryl radicals may be used. The viscose spinning solution may contain delustrants, casein or other protein, or other additional ingredients.  In an example, viscose is extruded into a bath containing sulphuric acid, sodium sulphate, magnesium sulphate, and zinc sulphate, and about 0.005 per cent of polymerized ethylene oxide.  Instead of polyethylene oxide there may be used polymerized propylene oxide or polymerized nonaethylene glycol. The spinneret may be made of gold, platinum-gold, platinum-rhodium, palladium-gold, tantalum, or artificial ruby.

Title: Improvements in or relating to the production of pure titanium and zirconium
IPC: C22B34/14
Filed: 1951-09-04
Abstract: 722,184. Extracting titanium or zirconium. LEVY, J. P., PICKARD, D. H., and PICKARD, L. Dec. 4, 1952 [Sept. 4, 1951], No. 20894/51. Class 82 (1). Titanium or zirconium is produced by reacting the vapour of the tetrachloride of the required metal in the presence of a moving inert gas, e.g. argon, helium or neon, with magnesium vapour and passing the reaction products while entrained in the inert gas through a zone cool enough to solidify the magnesium chloride before the particles are allowed to settle. In the apparatus shown for producing titanium, a melting vessel 23 charged with magnesium billets through a tube 25 and an outer vessel 12 in which the magnesium is vaporized are enclosed in a furnace (not shown) and argon from an inlet 17 is passed, through calcium or other gettering material 18 and a delivery tube 20, to the vessel 12. The argon stream from a nozzle 21 on the delivery tube acts with a Venturi 11 to inject magnesium vapour from the vessel 12 into a reaction vessel 10 where it reacts with a stream of titanium tetrachloride vapour entering through an inlet 15. The fine titanium particles and the mist of magnesium chloride so formed are carried by the argon to a cool zone 27, where the magnesium chloride solidifies, and finally to a receiver 30, where the mixed powder is collected. The argon, together with excess titanium tetrachloride, passes out from the receiver at 31 and enters condensers where the tetrachloride is removed and the cleaned argon-is recycled to the inlet 17. Electrostatic or cyclic precipitators may be fitted in the argon line to remove any remaining reaction products. When the receiver 30 is full it may be changed without interrupting the process by closing the valves 35-38 and opening the normally-closed valve 29, the argon then passing through the line 34. An amount of titanium tetrachloride slightly in excess of the stoichiometric proportion may be used to prevent " striking back " on to the magnesium pool.

Title: Improved additives suitable for lubricating oil compositions
IPC: C07F9/04
Filed: 1956-07-06
Abstract: The invention comprises additive compounds for lubricating oils (see Group III), prepared by phosphosulphurizing a hydrocarbon and reacting the product thus obtained with a C2 to C6 alkylene oxide. In the first stage of the reaction a hydrocarbon is reacted with a mixture of phosphorus and sulphur or a phosphorus sulphide, preferably phosphorus pentasulphide. Specified hydrocarbons are paraffins, olefins, acetylenic hydrocarbons, alkyl-aromatic or cyclo-aliphatic hydrocarbons, petroleum fractions, bright stocks, lubricating oil distillates and waxes.  In the second stage the product is condensed with the alkylene oxide at about 285 DEG  F. Specified alkylene oxides are ethylene and propylene oxides.  In an example a bright stock solvent is treated with phosphorus pentasulphide in a nitrogen atmosphere and the product is either reacted directly with ethylene oxide or treated with an activated earth in a carbon dioxide atmosphere before reaction with ethylene oxide.ALSO:Additives for lubricating oil compositions comprise the products obtained by phosphosulphurizing a hydrocarbon and reacting the product thus obtained with a C2 to C6 alkylene oxide (see Groups IV (a) and IV (b)).  They may be incorporated in synthetic, animal, vegetable or mineral lubricating oils, distillates derived from crude paraffin, naphthenic, asphaltic or mixed oils, together with the usual additives.  Various tests carried out on lubricating oil compositions containing the additives are described.ALSO:Additive compounds for lubricating oils (see Group III) are prepared by phosphosulphurizing a polyolefin in known manner and reacting the product with a C2 to C6 alkylene oxide. In an example a polyisobutylene having a molecular weight of about 1200 is reacted with phosphorus pentasulphide in an atmosphere of nitrogen and the product is treated with ethylene oxide.
