Patent GB-627904-A (GB)
Title: A process for the refining of volatile metal of silicon chlorides
IPC: C01B33/08
Filed: 1947-06-02
Abstract: The impure volatile chlorides resulting from the chlorination, in the presence of reducing carbon, of the oxide ores of silicon, titanium, zirconium, niobium and tin are freed from gaseous impurities such as chlorine, phosgene, hydrogen chloride and carbon monoxide by physical means, such as distillation under reflux or heating under reduced pressure, as a preliminary refining step.  The chlorides are subsequently purified by known methods such as volatilizing and passing through an absorbent tower, the absorbent of which remains effective longer when the chlorides have been subjected to the pre-refining treatment.

Title: Manufacture of sponge rubber
IPC: C08J9/00
Filed: 1950-06-14
Abstract: 671,284. Sponge rubber. UNITED STATES RUBBER CO. June 14, 1950 [June 24, 1949], No. 14815/50. Class 70 In a method for making sponge rubber, a vulcanizable fluid foam of Hevea rubber latex is prepared containing an alkali metal stearate, zinc oxide, and an alkali metal sulphide in the proportion of 1-20 parts per 100 parts of zinc oxide by weight the foam is shaped, gelled and vulcanized. In one method, natural rubber latex is compounded with 0.5-5 parts of alkali metal stearate and 2-8 parts of zinc oxide, each per 100 parts of latex solids, sulphur and accelerators, and 1-20 parts of sodium or potassium sulphide per 100 parts of zinc oxide. The compounded latex is then whipped to a foam which is gelled and vulcanized in the usual manner. A gelling agent, e.g. an alkali metal silico fluoride may be added in the proportion of 0.5-5 parts per 100 parts of latex solids to the latex before foaming or to the foamed latex before moulding' and the foam may thus be caused to gel at room temperature if desired. Gelling may also be effected by high frequency dielectric heating or by a low frequency alternating electric current. If the latex is preserved with NH 3  it is desirable to reduce the NH 3  content to below 0.2 per cent and preferably below 0.05 per cent before compounding and foaming.

Title: Improvements in or relating to the separation of sulphur from its suspension in aqueous liquids
IPC: C01B17/02
Filed: 1956-05-14
Abstract: Sulphur is extracted from an aqueous suspension thereof by adding a water-insoluble liquid of density greater than that of the aqueous suspending medium to the aqueous suspension and subjecting the two liquids to centrifugal separation.  The water-insoluble liquid may be a non-solvent for sulphur, or a solvent therefor either in the cold, e.g. carbon disulphide, or when heated, e.g. 1 : 2-dichloroethane, 1 : 2- or 1 : 3-dichloropropane, trichloroethylene, carbon tetrachloride, and perchloroethylene, and chlorobenzenes, chlorotoluenes, and chloroxylenes, including mixtures containing dichloro, trichloro, and tetrachloro isomers.  A wetting agent may be added to the aqueous suspension.  Other suspended material may be separated from the sulphur, when using an extracting liquid which is a non-solvent for the said material, by a fractional separation in the cold in a single centrifuge when the liquid is a solvent for sulphur in the cold, or a single separation in the cold in one centrifuge followed by a single separation at an elevated temperature in a second centrifuge when the liquid is a solvent for sulphur only at an elevated temperature.  The sulphur may be recovered from the extracting liquid by ordinary or steam distillation of the solvent. Solvent may similarly be removed from admixture with separated impurities.  The aqueous suspension may be produced by the treatment of hydrogen sulphide-containing gas with an aqueous solution of a ferric salt.  After extraction the aqueous suspension may be used for the further treatment of hydrogen sulphide-containing gas.

Abstract: 556,299. Catalytic apparatus process; INTERNATIONAL CATALYTIC OIL PROCESSES CORPORATION. Nov. 21, 1941, No. 15034. Convention date, Dec. 14, 1940. Drawings to Specification. [Class 1 (i) ] To regenerate the catalyst in a hydrocarbon conversion process an oxygen-containing gas is admitted at a temperature substantially below the maximum regeneration temperature, and is passed until the temperature of the mass falls to that of the entering gas, whereupon the temperature is increased by admitting hot regeneration gases from another converter in an intermediate stage of regeneration. For example, the oxidizing gas may be admitted at 700‹ F., the combustion products leaving at a maximum temperature of 1100‹ F., and the reheating being carried on until the temperature of the conversion reaction, namely 985‹ F., is attained. The operations are preferably carried out under pressure. After the conversion stage the reactor may be purged by a stream of hydrogen-containing gas which is a fraction of the reaction, product, after which the pressure is increased and the reactor again purged with the inert flue gas. After the regeneration and reheating, the conversion pressure is restored and the reactor again purged with hydrocarbon gas. The application of the process to a battery of six converters passing progressively through the cycle of operations is illustrated. Specifications 549,570 and 558,385 are referred to.

Title: A process of producing an antibiotic from escherichia coli
IPC: A61K35/74
Filed: 1951-06-26
Abstract: An antibiotic active against M. tuberculosis var. hominis is obtained by extracting E. coli with a strong solvent for lipids, removing the solvent and treating the extracts so as to remove firstly components soluble in water of pH 8 to 9 and secondly components soluble in water of pH 7 or less.  The bacterial mass obtained by centrifuging a culture broth is extracted preferably after grinding with sodium chloride, sodium sulphate or solid carbon-dioxide.  Extraction is by means of (a) a strong solvent for lipids followed by a weak solvent for lipids; (b) a weak followed by a strong solvent for lipids; or (c) partition between a mixture of strong and weak solvents for lipids.  Specified as strong solvents for lipids are (a) the water-immiscible solvents ether, petroleum ether and hydrocarbons, chlorinated hydrocarbons, e.g. methylene chloride and esters, e.g. ethyl acetate; and (b) the water-miscible solvents acetone, alcohols, e.g. ethanol and butanol and pyridine, in the anhydrous form or containing a specified amount of water.  Weak solvents for lipids are alcohols and ketones containing at least 40 per cent of water, except in the case of partitioning with strong solvents for lipids when the weak solvent for lipids need contain only 5 to 25 per cent water. After removal of solvent, the extract is treated with aqueous alkali e.g. potassium hydroxide of pH 8 to 9 followed by acidification to precipitate the antibiotic which may be recrystallized from petroleum ether.
