Abstract: A method and apparatus for heating fiber reinforced thermoplastics in sheet form in contact heating means, in which the thermoplastic is heated between bands in the space between two heating means which can be pressed against it and is at the same time held between an upper and a lower sheet-like or filament-shaped restraining means, which is respectively arranged between the thermoplastic and the band. After heating up, the thermoplastic is taken out of the heating zone together with the restraining means and bands, the bands firstly being detached from the thermoplastic, while the restraining means continue to bear against the thermoplastic, and subsequently the restraining means are detached from the thermoplastic.

Abstract: Glass matt reinforced thermoplastics suitable for the production of paintable parts, comprisinga) a thermoplastic matrix polymer of a viscosity under processing conditions corresponding to a melt flow index (MFI 230/2.16) of polypropylene of at least 250 g/10 min andb) one or more glass matts which, upon heating, bring about an expansion of the glass matt reinforced thermoplastics to at least 2.5 times the original thickness, optionally in combination withc) an addition of fine-particle, mineral fillers.

Abstract: A double belt press for the continuous manufacture of material webs. The press includes pressing belts which are supported by support strips mounted on pressing plates. The support strips form pressure chambers which receive fluid pressure media for acting on a surface of the pressing belt.

Abstract: Process for producing fiber-reinforced thermoplastics in a double-belt press in which the lateral sealing of the press space is formed from a porous profile which is mechanically supported against being laterally forced out and moistened with water before it enters the press.

Abstract: Process for extracting polyhydroxyalkanoates from the cell material of microorganisms by adding an organic solvent for the polyhydroxyalkanoate which is immiscible with water and which has a boiling point of below 100.degree. C., and, if appropriate, by adding water; stirring the resulting extraction mixture, if appropriate with refluxing; separating off the aqueous phase which contains the cell material in undissolved form from the organic phase; and injecting the organic phase into hot water, causing the dissolved polyhydroxyalkanoate to precipitate and the organic solvent to evaporate, and also isolating the precipitated polyhydroxyalkanoate flocs.

Abstract: Device for cutting band-shaped or strand-shaped material, having a cutting device in the form of a cutter roller, in which outwardly-pointing cutting edges which are arranged at a uniform distance from one another connect two circular disc-shaped or annular bodies to one another, which bodies hold the cutting edges, and the material to be cut via these cutting edges forms a lap superimposed in several coil layers, the radial innermost position of which lap is cut by the pressure which acts in intensified manner as a result of a loading body. The cutter blades, the cutting edges of which cut the material, are arranged for reducing the bending stress in such a way that they are at a setting angle alpha of 5.degree. to 25.degree. to the radial direction of the device, with the cutting edges pointing in the direction of movement of the cutter roller.
