  • Patent number: 4013744
    Abstract: A process for the manufacture of fibrids of thermoplastics materials by extruding molten thermoplastics through dies and breaking up the extrudate into fibers by means of a liquid medium causing shear stresses within a small volume, to which end the extrudate is passed to a zone of high energy dissipation so that it is completely divided up into fibers of the desired size in a single pass.

  • Patent number: 4013431
    Abstract: Gas mixtures containing ammonia and carbon dioxide are separated by fractional absorption in a solvent. The gas mixture and solvent are intimately mixed in a zone, the residence time of the gas in the mixing zone being restricted to a maximum of 0.1 second. Non-absorbed gas and solvent are then separated from one another and the gas separated off is subjected to a further absorption if necessary.

  • Patent number: 4014042
    Abstract: A magnetic tape cassette comprises a housing open on one side and, movable therein, a sheath enclosing a magnetic tape roll. Detachable retaining means in the cassette hold the sheath and the roll in position while the cassette is not on the recorder. The retaining means are detachable by unlatching means when the cassette is fitted to the recorder, so that, following a movement of the sheath, the cassette is opened to allow the roll to emerge at least partially from the cassette and the circumference of the roll to be rotated by means of a recorder-associated capstan provided outside the cassette. Further advantageous embodiments of the invention concern the cassette and the recorder. The cassette of the invention and the recorder associated therewith can be employed in all fields of magnetic tape recording and reproduction. Its application to a magnetic tape system with a self-threading tape end entails advantages.

  • Patent number: 4012573
    Abstract: An improved method of removing heat from polymerization reactions of normally gaseous monomers in the gas phase comprising feeding the monomer in liquid form to a polymerization zone, immediately after entering said zone, removing a portion of said gaseous monomer from the polymerization zone, liquefying said portion of monomer by cooling it at the same pressure as that prevailing in the polymerization zone, recycling the liquefied monomer to the polymerization zone together with fresh monomer in liquid form and causing said liquid monomer to change to the gaseous form immediately after entering said zone. The improvement consists in not only condensing the monomer outside the polymerization zone but also storing the same, in keeping the temperature in the polymerization zone constant by regulating the rate at which liquid monomer is fed to the zone, and in keeping the temperature and pressure in the polymerization zone within limits conducive to the gaseous state of the monomer.
