The invention relates to a device for stirring a liquid in a reactor and for injecting a gas into the said liquid in order to form a gas-liquid dispersion, comprising a) a drive device () positioned above the reactor, provided with a vertical output shaft () fitted at its lower end with at least one axial flow rotor () immersed in the liquid, b) means for introducing gas (and) above the axial flow rotor (), c) a deflector () placed above the axial flow rotor () preventing the gas-liquid dispersion from rising, and d) a deflector () placed below the axial flow rotor () converting the axial flow of the said axial flow rotor into a radial flow. This device may be used in shallow basins.

The invention relates to equipment for area-based surface treatment of an article by electric dielectric barrier discharge in the presence of a non-atmospheric controlled gaseous mixture, comprising a hollow metal electrode enabling the gaseous mixture to circulate therewithin and the mixture to be transported to a discharge area, whereby said electrode is divided into individual elements which can each be pivoted about a central axis to ensure sufficient distance between the element which is considered as being pivoted and the area of the article opposite the element in question so that the discharge cannot develop; the central pivoting axis is used as a channel for the circulation of the gaseous mixture inside the electrode and is provided with openings enabling the gaseous mixture to be evacuated to the discharge area; pivoting one of the elements of the electrodes blocks up the evacuating opening associated therewith and the gaseous mixture can only be evacuated via the evacuating openings of non-pivoted elements.

Methods for treating polymeric substrates by placing the substrate in a gaseous mixture and subjecting it to a dielectric barrier electrical discharge. The gaseous mixture, which has a pressure around atmospheric, contains a carrier gas, a reducing gas and an oxidizing gas. The amount of the oxidizing gas in the gas mixture is between about 50 ppm and about 2000 ppm by volume, while the amount of the reducing gas in the gas mixture is between about 50 ppm and 30000 ppm by volume.

A fibrous structure is described for use in hygienic articles such as diapers, sanitary napkins, incontinence guards, wipes and the like, having one or more polar, silicon containing compounds bound to at least one portion of the surface of the fibrous structure by interaction between the surface and the silicon containing compounds. The fibrous structure exhibits a predetermined degree of hydrophilicity and adhesion properties which are substantially unaffected by wetting of the fibrous structure. Absorbent, hygienic and textile articles comprising such a fibrous structure are also described.

A portable device for administering a gas. The device can supply at least one nostril of a user with at least part of a gas. The device includes at least one gas distribution nozzle and a support, with which the at least one gas distribution nozzle is supported or held in position on the face of the user. The at least one gas distribution nozzle is held along at least part of the outer wall or surface of the nose or cheeks of the user, when the device is positioned on the head or the face of the user. The at least one nozzle is outside the user's nostrils.

A process for producing disilane from monosilane comprising introducing monosilane into a reaction zone in which the monosilane is subjected to an electric discharge generated by a high frequency current. The monosilane is mixed with at least one inert gas selected from the group consisting of helium and argon. The pressure of the gaseous mixture in the reaction zone is between 0.1 and 3 bar, and the gaseous mixture is contacted in the reaction zone under electric discharge with a wall cooled to a temperature which is sufficiently low for the saturation vapor pressure of the disilane to be negligible, but not low enough for the monosilane to condense at the working partial pressure. Apparatus for conducting this process is provided.
