    摘要： Two-component loop yarns are composed of core and effect filaments, at least part of the core component consisting of aromatic polyamides, wherein the aromatic polyamides contain the structural repeat units of the formulae I and II--OC--Ar.sup.1 --CO--NH--Ar.sup.2 --NH-- (I)--OC--Ar.sup.1 --CO--NH--Ar.sup.3 --NH-- (II),where Ar.sup.1, Ar.sup.2 and Ar.sup.3 are each independently of the others a bivalent mono- or polycyclic aromatic radical whose free valences are disposed para or meta or comparably parallel, coaxial or angled to each other, and Ar.sup.2 and Ar.sup.3 each have different individual meanings within the scope of the given definitions, and the respective monomer components underlying the polymer are selected so as to produce an aromatic polyamide which forms preferably isotropic solutions in organic solvents.

    摘要： Porous carbon fibers, whose active centers are formed by pores that are filled at least in part by carbon and/or metal and/or metal carbide, obtainable by carbonization of organic or inorganic polymers, the use thereof for the adsorption or separation of gaseous substances, in particular of CO2, and also a method for the production thereof. First, a spinning mixture containing polyacrylonitrile-based polymer A and an organic or metallo-organic polymer B is produced. Next, the spinning mixture is spun to form mixed fibers of polymer A and polymer B. The mixed fiber is stabilized by oxidation. This is followed by carbonization or graphitization of the mixed fiber under non-oxidizing conditions in such a way that the polymer B forms a carbon and/or metal and/or metal carbide residue of at least 22 wt %, the residue forming active centers.

    摘要： A method monitors and measures the uniformity of tows with mechanical sensing elements in the course of production on a tow line. The tension of the running tow is measured upstream of a transport roll arrangement and is utilized as a measure of the uniformity of the tow. Irregularities in the tow result in tow tension determination outside a predetermined tension range, and when the determined tension measurement is outside that range the irregular tow portions are remove. Also, the frequency of tow tension determination outside a predetermined range may be used as an indication of tow quality and for removing substandard tows.

    摘要： Lightweight heat-conducting plates of compressed expanded graphite material have layer planes which are preferably disposed so as to be parallel to the surface so that heat conduction in a lateral direction is preferred to heat conduction perpendicular to the plate plane. The heat-conducting plates are suitable for the transmission of heat of floor-heating, wall-heating, ceiling-heating and other flatly disposed heating systems and air-conditioning ceilings, for the transmission of heat and the dissipation of heat in buildings, automobiles, machines, installations and containers. The heat-conducting plates are dimensionally stable without the addition of binder and aggregates and can be produced in a continuous process. A composite component having at least one heat-conducting plate and a method for production of heat-conducting plates are also provided.
