IPC: C08L89/00
Filed: 1923-07-30
Abstract: 224,273. Tsubata, M. July 30, 1923. Pigments; distempers.-Pigments are rendered suitable for use with oil or water by first treating them with an emulsion containing a colloid, such as gelatine or casein, water, drying-oil, formalin, ethyl or methyl alcohol, to form a formo-gelatinous coating on the particles, washing, drying and powdering, and secondly kneading the product thus obtained with an emulsion of a colloid such as gelatine or casein, or both, water, drying-oil, and ethyl or methyl alcohol. The final product is dried and powdered. The product of the first step may also be used with oil or gelatine water to form a paint. Glue or isinglass may be used instead of gelatine, and as drying-oils, wood oil, poppy-seed oil, linseed oil, perilla oil or boiled oil may be used with or without shellac varnish, Canada balsam, cocoa. oil, vaseline or castor oil, to adjust the viscosity. The oils may be used in gasoline or turpentine solution. Mineral pigments such as ultramarine, verdigris, vermilion, flowers of zinc, white lead, whiting, animal pigments such as cochineal or bone black, or vegetable pigments such as shikon may be treated by the process.

Abstract: 699,429. Dispensing cold gases. BRITISH OXYGEN CO., Ltd., and SCHUFTAN, P. M. Aug. 7, 1952 [Aug. 27, 1951], No. 20159/51. Class 8 (ii). A method of dispensing a low boiling point gas e.g., oxygen to meet a fluctuating demand from a steady supply e.g. an air rectification column comprises supplying the excess gas available when the supply exceeds the demand at a pressure in excess of the demand pressure to a storage medium of the gas in the liquid phase, and evaporating this liquid under reduced pressure during periods when the demand exceeds the supply. In operation liquid oxygen from the base of the low pressure column 14 of a conventional twostage rectification column 8 traverses pipes 18, 19 and a pump 22 where it is compressed to the demand pressure. a heat exchanger 5 where it is vaporized by incoming air and thence through a pipe 23<SP>1</SP> to the user. On the demand falling below the supply part of the liquid oxygen leaving the pump 22 is further compressed by a pump 24 and traverses a pipe 25, the exchanger 5, a valve 33 and a pipe 26 leading to a regenerator 27 where the vapour is cooled to saturation temperature before passing a check valve 29 to nozzles 30 located below liquid oxygen in an insulated container 31. To meet an increased demand for oxygen the valve 33 is automatically closed and valve 34 is automatically opened to allow vapour from above the liquid in the container 31 to traverse a pipe 32, the regenerator 27 and the pipe 23' leading to the user. Cold losses from the container 31 are made: up by feeding liquid oxygen from the pump 24 through a valved pipe 35. Excess oxygen from the column 14 is fed through a valved duct 21 to store.

Title: The antibiotic rubradirin
IPC: C12P1/06
Filed: 1964-05-14
Abstract: <PICT:1058686/C2/1> An antibiotic rubradirin gives a red colour in acid solution and a green colour in alkaline solution, it is effective against gram positive and negative bacteria; it is soluble in ethyl acetate, 1-butanol, methyl ethyl ketone, methylene chloride, methanol and benzene and relatively insoluble in water; it has the following elemental analysis: C=57.31%, H=4.69%, N=5.25% and O=31.36%; molecular weight 1026\sB12; ultra-violet absorption spectrum (Fig. 2) showing maxima at 264 mm , a = 28.48; 337 mm , a = 34.73 and 515 mm , a = 1.58; and infra-red absorption spectrum as in Fig. 1. Rubradirin is produced by cultivating Streptomyces achromogenes var. rubradiris NRRL 3061 (N.C.I.B. 9516) in an aqueous nutrient medium containing an assimiliable source of carbon and nitrogen under aerobic conditions. The temperature is 18 DEG  to 40 DEG  C., pH 6 to 8 and duration of cultivation 2 to 10 days. Rubradirin may be recovered from the clarified broth by (a) extraction or (b) adsorption. Extraction from a broth of pH 3.2, by means of a solvent such as methylene chloride, may be followed by precipitation by a non-solvent such as Skellysolve B.  Adsorption may be on strongly basic anion exchange resins, e.g.  Amberlite IRS-400 or on silicic acid, alumina or "Florisil" (Registered Trade Mark), followed by elution with a solvent.  Further purification may be by counter-current distribution, e.g. in the solvent system Skellysolve B, acetone and water (5 : 5 : 1). Rubradirin forms salts with organic and inorganic bases, e.g. alkali metal, alkaline earth metal and amine bases.

Filed: 1928-07-11
Abstract: 320,607. Grapes, G. Hamilton-. July 11, 1926. Vaporizers, external. - Relates to devices for trapping unvaporized particles of fuel in the charge, more especially when the engines is cold, this unvaporized fuel being vaporized and returned to the mixture stream. The mixture passes from the carburetter through a curved separator element 6 connected by a flange 7 to the inlet manifold, and provided at the middle of its length with a passage 8 opening into an exhaust-heated retort 14. The inlet of the element 6 is provided with a trap device 9 containing a catch groove 10 similar to that described in Specification 293,824, the fuel trapped in the groove 10 passing through a conduit 12 to the uppermost trough 13 of the retort 14. The trough 13 communicates with a collection chamber 17 through a conduit 16 controlled by a thermal valve 5 which closes at a predetermined temperature. The chamber 17 communicates through an overflow conduit 24 and a vapour discharge conduit 25 with an overflow chamber 22, and is provided with a partition 18 containing a port controlled by a thermal valve 21 which opens at a predetermined temperature. The top of the chamber 22 comprises a horizontal portion 25<a> and an inclined corrugated portion 26 which is integral with the wall 27 of the chamber 17, the space 38<a> between the retort 14 and the top of the chamber 22 being traversed by the exhaust gases which enter at 38 and pass out through the muffled connection 39. Below the corrugated portion 26 is a corrugated tray 33 provided with strips 36 of capillary material, the space between the parts 26, 33 communicating at one end with the passage a between the partition 18 and wall 27, and at the other with a channel 42 partly surrounding the exhaust outlet 39. The chamber 22 is provided also with a suction conduit 43 leading to the catch groove 10, and the retort 14 is provided with an air inlet passage 44 as described in Specification 283,240. When the engine is cold, the major part of the unvaporized fuel is trapped in the device 9, 10 and passes through the conduit 12, trough 13, valve 15 and conduit 16 to the chamber 17, from which any excess overflows through the conduit 24 to the chamber 22. As soon as the chamber 38<a> reaches a predetermined temperature, the valve 21 opens, and the fuel collected in the chamber 17 flows over the tray 33 and is vaporized, the vapour passing through the passage a and chamber 17 to a conduit 40 leading to the entrance of the element 6. The liquid from the chamber 22 is also drawn by capillary action over the tray 33 and vaporized. When the engine leaches normal running, the valve 15 closes, the fuel collecting in the trough 13 overflowing into the retort 14 where it is vaporized, any unvaporized particles passing the trap 9 entering the retort through the passage 8. Should the liquid in the chamber 22 rise above the level of the mouth of the conduit 43, it is drawn by suction into the groove 10.
