Textile quality polymeric fibers and thin films that are highly sorbent for organic and other vapors, mists and solutes. The fibers and films comprise a polymeric matrix with a system of interconnecting micropores, and are highly loaded with particulate sorbents such as activated carbon. The fibers and films are manufactured by forming a melt blend of the sorbent particles, the polymer and a selec...

A process for the hydrolysis at high pressures and temperatures of organic matter with a ligno- cellulose content, particularly ground wood, bagasse and corn on the cob waste comprises three steps, whereby the fractions of the organic matter, namely pentoses, lignin and hexoses are separated from one another in succession in separate steps in the process. Both prehydrolysis for separating out the ...

The heat transformer has a compressor in the first heat pump stage and another compressor in the second stage. A condensor, a medium vessel and an expansion valve are fitted between the two compressors. The transformer, using pressure steam overheated by medium components from stage one and condensate with fed steam from stage two, generates suction steam with low fluid content and low degree of o...

A furnace for smelting and/or redn. has at least one through channel for lining material in which the light arc electrodes are positioned. The electrodes are completed by a jet burner for oil, gas and/or powder-form fuel placed in the channel. - The jet burner is fitted annularly around the hole or channel for lining material, and is provided with water-cooled lance walls. Its point is made of non...

The expansion unit is anchored in a hollow chamber through radial expansion, and comprises at least three sections, i.e. two end sections and at least one central section. The end sections can be pushed towards each other so that the unit is compressed axially. The central sections take the form of initially inclined plates or rings so that they form an acute angle towards the cross-sectional plan...
