摘要： A process and apparatus for guiding a continuous moving tow in synthetic fiber manufacture. The profile (the thickness distribution and width) and the position of the tow are continuously sensed in a non-contact manner and an appropriate electrical signal is generated. This electrical signal is used to control the profile and the position of the tow in such a way that its profile and position stay within predetermined target value ranges. The tow geometry is preferably sensed using a CCD camera, while the tow geometry is controlled using tow-engaging deflecting means. In this way it is possible to optimize tow profile and position, for example for entry into a stuffer box (FIG. 1).

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： 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.
