Title: Production of carboxylic acids by microbiological oxidation of hydrocarbons
Inventor: HUMPHREY ARTHUR EARL
IPC: C12P7/40
Filed: 1966-10-05
Abstract: A hydrocarbon substrate is converted to a carboxylic acid by subjecting it in admixture with an aqueous nutrient medium and in the presence of an anion exchange resin to the aerobic action of a hydrocarbon-consuming micro-organism that converts the hydrocarbon into a carboxylic acid, the acid becoming bound to the resin; the anion exchange resin containing the acid is separated and the acid is displaced from the resin.  The product contains at least one carboxylic group and may contain other oxygen-containing groups such as hydroxyl, keto or aldehydo.  The nutrient medium used should contain sources of available nitrogen, phosphorus, sulphur and magnesium and may contain various trace elements and vitamins. Preferably a weakly basic anion exchange resin is used. The acid product may be recovered from the resin by contacting it with an acid, e.g. hydrochloric, phosphoric, formic or acetic acid or by means of caustic soda or other alkali metal hydroxide in which case the alkali metal salt is obtained.  In the examples various micro-organisms are used to convert (a) p-xylene to dihydroxy p-toluic acid, p-toluic acid and dimethyl muconic acids; (b) naphthalene to salicylic acid; (c) methyl benzenes to methyl-substituted muconic acids, 2,3-dihydroxybenzoic acids and alkylbenzoic acids; (d) dimethylnaphthalenes to methylcarboxynaphthalenes; and (e) anthracene and phenanthrene to hydroxynaphthoic acids.  Among the micro-organisms used as Nocardia corallina, Nocardia salmonicolor, Corynebacterium renale, Streptomyces achromogenes and Pseudomonas aeruginosa.

Title: Process for the purification of methyl ethyl ketone
Filed: 1961-12-22
Abstract: Impure methyl-ethyl ketone containing water, aldehydes and chlorination products, e.g. chloroketones, especially 3-chlorobutanone-2, is purified by intimately mixing the impure ketone with an aqueous alkali metal hydroxide solution of 20 to 30% by weight strength at 90 DEG  to 150 DEG C. under a pressure sufficient to ensure that no substantial evaporative loss of organic phase occurs; then separating the organic layer and recovering the pure ketone therefrom by distillation. The preferred volume ratio of ketone to alkaline solution is 2:1 to 1:10 and the alkali treatment lasts for 1 to 30 minutes.  The mixing is performed in an apparatus made from, or lined with, corrosion-resistant material and designed for intense mixing of two phases.  It is of advantage to prepurify the starting material by distillation and degassing.  Specification 876,024 is referred to.

Title: Hexetidine salts
IPC: A61P31/04
Filed: 1976-11-05
Abstract: There is described a process for the preparation of novel salts of hexetidine with aromatic carboxylic acids of the formula II <IMAGE> in which n denotes 1 or 2 and if n = 1 the substituent X is -COOH, -OH, -NH2, -SO3H or -SO2NH2 with the proviso that X is present as -COOH or -OH in the 4-position, and if n = 2 X has the prior meaning with the proviso that different X radicals are present. The base is reacted with the said acid in a solvent and the salt is obtained by crystallising out. The salts prepared are distinguished by poor solublity in organic solvents and can therefore easily be separated off from accompanying by-products. Pure hexetidine can also be obtained from the resulting salts by reactions with an aqueous base. Since both the salts and the pure hexetidine have antimicrobial activity, they are used in particular as an antiseptic for the oral mucosal membrane.

Title: Measuring the emission current of a crt
IPC: H05G1/26
Filed: 1973-10-03
Abstract: 1452108 Measuring emission current PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 3 Oct 1973 [6 Oct 1972] 46166/73 Heading G1U In a cathode ray tube, emission current is measured by supplying the tube high tension VH through a winding of a transformer T 2  and causing the emission current IE to flow alternately in opposite directions through two halves of that winding under the control of diode switches D 1 - D 3  controlled by the tube filament supply. In the double-focus x-ray tube shown, the supply voltages V 1 , V 2  are in-phase and substantially equal. In one half-cycle, diode D2 conducts the emission current from B through one half of the primary winding of the transformer T 2 . In the other halfcycle, diodes D2, D3 are forward biased, allowing the current from whichever filament is emitting to flow in the opposite direction through the other half of the winding. The transformer secondary voltage across R S , indicates the emission current magnitude. If the supply voltages are anti-phase or differ greatly in amplitude, D3 is removed and terminal P 2  connected directly to the free end C of the second filament Fig. 3 (not shown). If only a single filament is present Fig. 1 (not shown), terminals P 2 , P 1  are connected across the filament supply. In both these examples, the diode switching is effected by the voltage difference between P 1  and P 2 .
