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: The invention relates to a method for the production of nonwovens, in which a solution of cellulose carbamate in N-methylmorpholine-N-oxide is forced through the holes of a nozzle beam and is stretched by a multiple by means of an airflow. The fibre curtain which is formed is laid down on a perforated conveyer belt, washed and dried. The invention likewise relates to nonwovens of this type and the use thereof.

Abstract: The invention relates to a method for the production of non-woven fabrics, in which a lyotropic solution of cellulose carbamate in N-methylmorpholine-N-oxide (NMMNO) is spun into a plurality of filament yarns by means of extrusion through a nozzle beam containing a plurality of openings via an air gap into a regenerating bath, said filament yarns being intermingled subsequently by being subjected to a flow with gaseous medium and/or fluid. The invention likewise relates to non-woven fabrics of this type and the use thereof.

Abstract: The invention relates to high-strength fibres and other moulded articles comprising cellulose carbamate or cellulose which is obtained by regeneration of cellulose carbamate, and also production thereof by extrusion of a solution of cellulose carbamate in N-methylmorpholine-N-oxide (NMMNO).

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 invention relates to a proton-conducting polymer membrane and to a method for the production thereof. Starting from a catalyst layer, which is homogeneously deposited on the polymer membrane (3), the catalyst layer is subdivided into a number of catalyst segments (1a, 1b) by microstructuring so that adjacent fuel cell units of a planar fuel cell arrangement can be realized in the smallest possible space.

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.

Abstract: Apparatus for the production of extruded blown cellulose film from a solution of cellulose, water and an amine-oxide, which includes:—extrusion apparatus for continuously extruding a cellulose solution to produce a cellulose film;—solidifying apparatus for solidifying the extruded cellulose film;—drawing apparatus positioned downstream of the extrusion apparatus for continuously drawing the extruded cellulose film from the extrusion apparatus; and a tubular member for containing precipitation apparatus and for receiving an extruded blown film wherein the tubular member is situated within a precipitation bath. The invention also includes a method of extruding blown film.

Abstract: The invention relates to a method for the direct production of fibres, films, beads, sponges and other moulded articles made of cellulose carbamate which was obtained by conversion of cellulose with urea at increased temperature and direct dissolution of the reaction product in sodium hydroxide solution without an additional washing and cleaning operation.

Abstract: The invention relates to a method for the production of cellulose carbamate by reactive extrusion and for the production of moulded articles made of regenerated cellulose. The method for the production of cellulose carbamate is based thereby on the activation of cellulose, subsequent separation of the activation solution and following thereon reactive extrusion of the activated cellulose. Typical examples of moulded articles which can be produced therefrom are fibres, films, beads, sponges or sponge-type cloths.

Abstract: A yarn false twist texturing apparatus which includes a yarn heater, a yarn cooling device, and a yarn twisting unit serially arranged along a yarn path of travel. The cooling device is composed of a cooling tube, and yarn guides are arranged so that the yarn advances spirally on the surface of the outside periphery of the tube. A yarn lifter is positioned so as to lift the advancing yarn from contact with the outside periphery of the cooling tube over a partial length of the cooling tube, so that the cooling effect can be influenced without significantly changing the spiral looping on the cooling tube.

Abstract: The invention concerns a profiled part and aggregates for making same. The aggregates contain a material for plastic matrix technique and an adherence promoter. Regenerated cellulose fiber elements are incorporated in the matrix material. The characteristic profile of a profiled part made from such aggregates corresponds substantially to that of profiled PC/ABS parts, the profiled part of the invention being, however, capable of being produced at a more advantageous cost, being more recyclable and being, moreover, capable of being shaped at lower temperatures.
