Control process for producing an aqueous slurry of solid carbonaceous fuel having a desired solids concentration for feed to a partial oxidation gas generator by grinding together in a size reduction zone a recycle aqueous slurry stream comprising carbon-containing particulate solids, a stream of solid carbonaceous fuel, and a specific amount of make-up water. No valves are in the line or path bet...

For the production of a monoaxially stretched shaped article of polytetrafluoroethylene (PTFE), a pasty composition containing PTFE powder is worked continuously into a moulding, which is passed over a plurality of rollers or rolls, is heated and stretched, the moulding being heated before applying the stretching tension to a temperature of between 327 and 450 DEG C, preferably between 350 and 390...

An opacified stretched molded product has a total light transmittance of 50% or less and a density of 0.89 or less and comprimises a composition containing 100 parts by weight of polypropylene and 3 to 40 parts by weight of a cyclopentadiene petroleum resin, said molded product being a product stretched in at least one direction. The invention also provides a resin composition comprising 100 parts...

2026009 9008799 PCTABS00001 The invention relates to an improved, castable, synthetic resin material, suitable for use in dental and medical restorations, as a replacement for dental enamel and hydroxyapatite bone material. This material is also useful for electrical insulation. More specifically, the invention provides a filled reinforced resin matrix comprising a castable resin; from 5 to 50 % v...

The process is characterised in that cefodizim is brought into solution using 1.5 - 2.5 mol of an organic amine base in ethanol with a water content of 4 - 15%, and the disodium salt of cefodizim is crystallised out by the addition of a sodium donor.

Ferroelectric smectic liquid crystal mixtures are provided consisting of two constituents; a smectic host and another containing a chiral compound in which rotation of the chiral centre relative to the molecular core is sterically hindered, so that the chiral compound induces a high Ps in the mixture. A preferred class of chiral compounds is those derived from naturally occurring compounds with ch...

Certain 3 min -fluoro pyrimidine and purine nucleosides have been found to have potent antiviral activity particularly against Human Immunodeficiency Virus (HIV).

Auxin and cyto-quinine activity of biologically active materials is determined selectively where an isolation of a plant, reared undre sterile condition in vitro is, incubated on a substrate contg. Murashige, Skoog micro-acid micro-elements, saccharose, in-inositol, thiamine and the cpd. being determined Activities are determined: by qualitative and/or quantitative assessment of root growth or sho...

A key operated electric switch comprises a rotary switching member 13 connected to a rotary lock barrel 2 which is operable by any one of a plurality of different keys 3/I-V. The angular movement of each key is limited by shoulders 3/a'-d' on annular members 4, 5 fixed in a housing 1 and separated by a ring 6, the amount and direction of rotation being determined by the particular arrangement of s...

The invention concerns a high pressure sodium discharge lamp with an elongate discharge vessel (1) having a metallic band (30) proximate an end of the discharge vessel (1) and disposed on the discharge vessel circumferentially thereof. The surface of the discharge vessel is free of further auxiliary conductors. Means are provided for applying a voltage to the metallic band (30) for inducing ioniza...
