A method and apparatus for metering and dispensing an active ingredient, such as an insecticide, fumigant, fertilizer or room freshener. The active ingredient is placed in a container (6) and a pressurised propellant is subsequently introduced from a source (1) via conduits (3, 9). The propellant serves to absorb the active ingredient which is dispersed from the container via conduit (5) through a...

The invention relates to a method for forming the primary web of a mineral fibre mat onto a moving, pervious base by transporting fibres onto the base by means of a stream of air or a corresponding means. In accordance with the invention, the stream of air is adjusted to minimise the pressure difference over the forming base. The invention also relates to an apparatus for the purpose of implementi...

To remove copper from iron-rich melts, for example pig iron or steel melts, it is proposed sulphur be introduced into or applied to the melt bath in an at least stoichiometric amount based on Cu and the liquid Cu2S (copper matte) phase be drawn off. In the case of carbon- rich melts, a phase separation into a Cu-rich fraction and an Fe-rich fraction can be carried out in a first process step.

In a process for dechroming steel slags, oxygen is introduced into the liquid steel slag in an amount sufficient to convert iron quantitatively into iron oxide and at least 5% by weight of the iron oxide present in the slag into iron(III) oxide.
