The present invention provides a burner for the partial oxidation under pressure of a first fluid by the second fluid. This burner comprises two fluid introduction tubes, one being internal to the other, with each of the tubes comprising a plate, and with each plate having several holes and a plate of the external tube has holes placed opposite the holes in the internal plate.

This invention relates to a novel process for the production of polyurethane via an intermediate stage of aqueous dispersions of oligomeric polyurethane prepolymers having ionic and/or non-ionic hydrophilic groups which ensure their dispersibility in water, followed by conversion of these water-dispersible oligomers into cross-linked high molecular weight sheets.

The invention relates to a laminate based on a cured resin mixture of an unsaturated polyester and a monomer containing a vinyl group and reinforcing fibres in the form of a knitted fabric, characterized in that a resin mixture is applied, that in set condition and without reinforcement, has a tensile strength of 5-12 N/mm<2> at an elongation at break of 90-400%.

A method of increasing the strength of wood through impregnation thereof with a liquid containing a polymerizable monomer and/or oligomer and a setting agent, said agent being inactive at room temperature levels but activated when heated or exposed to radiation. The wood is impregnated with said liquid and thereafter heated in an oven or exposed to radiation in a radiation chamber.

Liquid crystal display devices having very small cell thicknesses are obtained by means of underetching techniques. Via etching holes (17, 29, 31) an auxiliary layer (27) between a supporting plate (2) and a cover plate (14) is removed. Dependent on the technique used spacers (18) are formed at the area of the etching holes or in between the etching holes. The device obtained has a uniform thickne...

The thermographic plate consists of a carrier film, a latex-based optically inhomogeneous black layer applied thereto and of a layer containing liquid crystals. The thickness of the black layer amounts to between 4 and 18 mu m. By virtue of this coordination of the thickness parameters, particularly high color intensity and hence correspondingly high image quality are obtained in the diagnosis of...

In a double-walled tank for low-temperature liquids, such as a liquid gas, an inner tank forms a primary safety casing while an outer tank, enclosing the inner tank, forms a secondary safety casing. The inner tank includes a base and an upwardly extending side wall with at least the base being formed of metal. Preferably, the outer tank is formed of reinforced concrete. A thermal insulation layer ...

Lubricating oil additives having both dispersant and viscosity index-improving properties are prepared by reacting a selectively hydrogenated star-shaped polymer having at least four areas of polymers or co-polymers of dienes and monoalkenyl arenes with an alpha-beta unsaturated carboxylic acid or derivative, and then reacting the resulting intermediate with an amine and/or alkane polyol.

Device comprises an EL element section (1) consisting of many thin film EL element cells formed so as to emit white light and a colour filter section (2) consisting of filters of set colours provided on the surface of the EL element section in correspondance to the various cells and in which a colour display is produced by controlling voltages (V) imposed on the EL elements in accordance with pict...

These organised structures may be either fibres or membranes. According to this process, a sample of animal or human tissue, washed and asepticised beforehand, is ground in a saline solution to solubilise the collagen present in the said sample. A catalyst for reconstituting the collagen fibres is then added to the extract obtained, consisting of collagen fibrils in a minimum quantity and free fr...

A contaminating metal on a cracking catalyst is passivated by the use of antimony, tin, and a reducing gas.

The present invention comprises the epitope recognized by the human monoclonal antibody 16-88, the human tumor antigen containing this epitope, which we have identified, isolated and characterized, and anti-idiotypic antibodies to human MCA 16-88, which comprise the same epitope. The invention also relates to the use of antibodies to the antigen containing this epitope for diagnosis and monitoring...

The present invention relates to a packaged single male incontinence protector of the kind which comprises a back piece (5) which has formed therein a cut-out (6) and which is intended to be brought beneath the scrotum and up to the root of the penis. According to the invention those parts of the protector which in its flat state lie on respective sides of the cut-out and extend substantially outw...
