Title: Process for producing 5-ribonucleotides
IPC: C12P19/32
Filed: 1964-03-20
Abstract: 51-Inosinic acid, 51-xanthylic acid and 51-guanylic acid are obtained by contacting an enzyme source of bacterial origin, having nucleoside phosphotransferase activity for producing 51-nucleotide from the corresponding nucleoside and a phosphate donor, with a solution containing the corresponding nucleoside and a 51-nucleotide other than that to be synthesized, allowing biochemical phosphorylation to take place to produce the desired 51-nucleotide while maintaining the pH of the solution in the alkaline range, preferably between 7.0 and 10.0, the accumulated 51-ribonucleotide may be recovered by a conventional procedure.  The production of the 51-nucleotide may be promoted by the addition of cupric and/or arsenic salts, the most suitable concentration of metallic salt being from 10- 3 to 10- 2 mole.  Bacteria which have the ability to synthesize 51-nucleotide from the corresponding nucleoside and a phosphate donor include species which belong to the genera Pseudomonas, Serratia, Flavobacterium, Staphylococcus and Achromobacter.  51 - Nucleotides which may be used as the phosphate donor include 51 - adenylic acid, 51 - cytidylic acid, 51 - uridylic acid, 51-desoxyadenylic acid and 51-thymidylic acid.  The enzyme source may be prepared by submerged culture, stationary culture or surface culture, preferably at a temperature of from 20 DEG  to 37 DEG C. and for an incubation period of from 10 to 60 hours, in a culture medium containing a suitable amount of an organic or inorganic nitrogen source, such as peptone, meat extract, corn steep liquor, yeast extract, dry yeast, hydrolysate of soybean protein or an inorganic ammonium salt, and a suitable amount of carbon source, such as molasses, glucose or hydrolysate of starch, and a suitable amount of inorganic salts.  The enzyme source may be in the form of, for example, living bacterial cells, cultured broth, living cell suspensions, dried cells, crude extract or enzyme preparation.  Examples are given for the preparation of 51-inosinic acid in the presence of sodium-51-uridylate and copper sulphate or sodium arsenate, and of 51-guanylic acid in the presence of sodium-51-cytidylate or sodium-51-uridylate, and sodium arsenate.
Patent GB-746818-A (GB)
Title: Improvements in or relating to fuels for gas turbine engines and improved method of operating gas turbine engines
IPC: C10L1/18
Filed: 1951-05-03
Abstract: A fuel for gas turbine engines comprises a vanadium-containing petroleum residue fraction and a minor proportion of an aluminium salt of an organic acid, this salt being soluble in the petroleum residue fraction.  The petroleum residue fraction may be a furnace oil and the amount of aluminium salt may be such that the fuel contains up to 3 per cent of aluminium.  The presence of the aluminium salt prevents or minimizes the build-up of inorganic deposits or formation of scale on the turbine blades and other parts of the engine and thereby prevtnts or minimizes corrosion. The aluminium salt may be a salt of fatty or naphthenic acids, particularly of (a) stearic acid, (b) fatty acids (e.g. ethylhexoic and isononanoic acids), obtained by oxidation of higher aldehydes produced by the oxo reaction using, as oxo feedstock, petroleum olefins or olefin polymers such as diisobutylene, or (c) fatty acids obtained by the partial oxidation of paraffin hydrocarbons. According to the Provisional Specification, other oil-soluble or oil-insoluble compounds of alkali metals, alkaline earth metals, magnesium, aluminium, zinc, copper or lead may be employed, as set out in Provisional Specification 745,621, instead of the aluminium salt. Specification 697,101 is referred to.

Title: Improvements in or relating to combinations of two relatively reciprocating coaxial elements
IPC: F16J15/56
Filed: 1961-04-05
Abstract: 966,561. Compressors. PHILIPS' GLOEILAMPENFABRIEKEN N.V. April 5, 1961 [April 8, 1960], No. 12182/61. Heading F1N. [Also in Division F2] A seal is effected between two relatively reciprocating co-axial elements e.g. a movable rod 10 and a stationary vertical sleeve support 11a, 11b, Fig. 1, by a metal sleeve 15 of substantially rectangular longitudinal section having a length equal to at least three times its thickness which engages one element 10 and is engaged by one or more elastic rings 17 accommodated in the other element 11a, 11b, the periphery of the sleeve being subjected to a complex of forces which are directed towards the element 10 in a zone located asymmetrically of its length and are so proportioned that, under the action of a pressure produced in a fluid located between the sleeve 15 and the element 10 as a result of relative movement between the elements, the sleeve is elastically deformed against the action of the applied forces. The sleeve serves to separate from each other spaces A, B, containing respectively a high pressure gas and a low pressure gas and oil. Springs 14 mounted on a ring 13 exert on a shoulder 15b formed at the lower part of the sleeve facing the space B a uniformly distributed force greater than that exerted radially on the remainder of the sleeve by the high pressure gas. During upstroke of the rod 10 oil carried by it will be arrested by the sleeve. On the downstroke any oil having leaked past the sleeve towards the space A is, as a result of the rod movement, forced in a wedge-like manner between the sleeve and the rod and pumped back towards the space B. The sleeve 15 is of white metal and may have a nylon lining. In a modification, Fig. 2 not shown, the force exerted on the lower part of the sleeve is produced by the pressure of a medium fed through channels in the sleeve support. In a further modification, Fig. 4, the greater force is exerted on the top part of the sleeve facing the higher pressure space A so that, on the upstroke of the rod, oil, or gas if the space B contains only gas, is carried past the sleeve towards the high pressure space whilst, on the downstroke, high pressure gas is prevented from reaching the space B. In a still further modification, Fig. 5 two sleeves separated by a space C are arranged in the sleeve support, the upper sleeve 52 acting as an oil arrester and the lower sleeve as an oil pump so that oil is carried into the space C and provides a liquid seal preventing leakage of gas from the high pressure space A to the low pressure space B. A spring-controlled safety valve 71 is provided in the sleeve support to prevent excessive rise in the oil pressure in the space C. The Specification states that the sleeve may be mounted in a piston movable in a cylinder.
