A method and apparatus for fragmenting a substance by discharging pulsed electrical energy through the substance is disclosed wherein electrodes are placed in contact with the substance and a series of measuring pulses are discharged into the substance to determine the characteristic pulse and the characteristic impedance of the substance. Based upon the series of measuring pulses at least one fra...

The foams are produced by reacting polyisocyanate and waterglass without use of a blowing agent. Foaming of the reaction mixture is achieved by the CO2, released in the reaction of isocyanate groups with water, in a controlled manner by the addition of a polysiloxane/polyether block copolymer.

The invention relates to new adhesion primer compositions for fluorine-containing coating. The adhesion primer consists essentially of epoxy and/or epoxy-phenolic resins and of methacrylic resin(s). The invention also relates to metal/fluorine-containing coating composite materials and to a technique for manufacturing these materials.

A process for the production of silicon in a low-shaft electric furnace, in which raw-material blanks are first formed which contain fine-grain silicon dioxide, e.g. in the form of sand, and carbon in excess in respect of the reduction to silicon carbide and the raw-material blanks are introduced into the low-shaft furnance as a charge in mixture with silicon dioxide in lump form. The silicon diox...

The present invention relates to an absorbent product, such as a diaper, a sanitary napkin or an incontinence guard, including a cellulose fluff-pulp absorption pad which is comprised of two mutually separate material layers (3, 4), of which the inner pad layer (3), intended to lie nearest the wearer's body in use, is soft, has slight flexural rigidiy and a bulk density of more than 13 cm<3>/g, an...
