Abstract: The invention relates to a method for the production of a precursor for the production of carbon- and activated carbon fibers according to the wet- or air-gap spinning method, in which a solution of lignin and a fiber-forming polymer in a suitable solvent is extruded through the holes of a spinning nozzle into a coagulation bath, the formed thread is stretched and subsequently treated, dried at an elevated temperature and then wound up. The lignin-containing thread is an economical starting material for the production of carbon- and activated carbon fibers.

Abstract: The invention relates to a system for visualizing and simulating personal knowledge structures in a company which has one or more business units. It comprises a first server for storing a first dataset, which describes a model of the company structure, wherein for each employee position in the company an employee target profile is defined, which comprises an employee target competence profile; and for storing a second dataset, which specifies the sales achieved for the individual business units; and for storing a third dataset, which depicts recorded employee actual competence profiles. Furthermore, it contains a second server which comprises a program that calculates a plurality of indexes based on the data of the first dataset, second dataset, and third datasets, in particular the human potential and/or the economic temperature.

Abstract: The invention relates to a method for the production of a precursor for the production of carbon—and activated carbon fibers according to the wet—or air-gap spinning method, in which a solution of lignin and a fiber-forming polymer in a suitable solvent is extruded through the holes of a spinning nozzle into a coagulation bath, the formed thread is stretched and subsequently treated, dried at an elevated temperature and then wound up. The lignin-containing thread is an economical starting material for the production of carbon—and activated carbon fibers.

Abstract: In a method for connecting an electrical conductor to an electrical contact part, wherein the contact part has deformable legs the legs are deformed by means of a bending die in such a way that the legs press the conductor with the contact part in a force-locked manner, wherein the contact part is acted upon in so that at least the legs are materially connected to each other. A device includes a bending die for connecting an electrical conductor to an electrical contact part, wherein the contact part has deformable legs and the bending die is designed to deform the legs in such a way that the legs press the conductor with the contact part in a force-locked manner, and wherein the device also includes a laser welding device designed to act on the contact part so that at least the legs are materially connected to each other.

Abstract: The present invention relates to a cellulose carbamate spinning solution, the cellulose carbamate being dissolved in at least one ionic liquid. Furthermore, the invention relates to a method for the production of blown films in which a solution of cellulose carbamate in an ionic liquid is extruded into a coagulation bath, and also to the films produced with the method and the use thereof.

Abstract: A process for manufacturing free-flowing pellets based on cellulosic spun fibers. The process includes a) wetting at least one cellulosic spun-fiber strand with a preferably aqueous dispersion of a polymer and/or an oligomer for the purpose of applying sizing, b) drying the at least one spun-fiber strand, and c) comminuting the at least one spun-fiber strand into pellets. The free-flowing pellets are made from at least one comminuted spun-fiber strand having sizing made from a polymer and/or an oligomer. A fiber-reinforced thermoplastic includes finely distributed free-flowing pellets for manufacturing fiber-reinforced performs.

Abstract: The present invention relates to a cellulose carbamate spinning solution, the cellulose carbamate being dissolved in an ionic liquid. The invention relates furthermore to a method for the production of nonwovens in which the cellulose carbamate spinning solution is pressed through the holes of a nozzle bar and stretched by a multiple by means of an air flow. The formed fiber curtain is laid on a perforated conveyer belt, washed and dried. Likewise, the invention relates to nonwovens of this type and also the use thereof.

Abstract: A lignin derivative is produced from a lignin with the empirical formula L(OH)z, where L is a lignin without hydroxyl groups, OH are free hydroxyl groups bonded to L, and z is 100% of the free hydroxyl groups bonded to L. The lignin derivative has free hydroxyl groups that are derivatized with divalent residues Rx and monovalent residues Ry that are bonded to L via an ester, ether, or urethane group. A shaped body comprising the lignin derivative can take the form of a fiber, e.g. as precursor fiber for the production of a carbon fiber. A carbon fiber can be produced from the above-mentioned precursor fiber.

Abstract: A rack conversion system mounts to an existing storage rack and includes lateral tracks for side to side movement of forward bins and longitudinal tracks for front to rear movement of rear bins. The bins are sized to efficiently store a particular item, for example, paper files. The forward bins are movable side to side along the lateral tracks and reside in front of the rear bin. The rear bins are moveable front to rear along the longitudinal tracks and are normally positioned to the rear to allow the side to side movement of the forward bins. The lateral tracks are preferably mounted below the forward bins and do not interfere with the movement of the rear bins, and the longitudinal tracks are preferably mounted above the rear bins and do not interfere with movement of the forward bins.

Abstract: A method and a computer system for operating at least two interconnected control units. The control units access sensor data and each execute at least one computer program for controlling operational sequences, in particular in a vehicle. The control units exchange synchronization information with one another. In order to design and refine a computer system in a way that will enable even especially complex operational sequences, as required in a modern motor vehicle, for example, to be controlled and/or regulated simply and cost-effectively with the aid of the computer system, using conventional control units, the control units execute the same computer program time-synchronously using a settable time lag.
