Title: Lignin removal method
Inventor: NIMZ HORST H
IPC: D21C9/153
Filed: 1989-01-23
Granted: 1993-06-29
Abstract: ABSTRACT            Lignin contained in a cellulosic or lignocellulosic pulp product is removed by contacting the product with a gaseous medium containing ozone in the presence of a liquid agent which is a lower fatty acid, such a formic, acetic or pro-pionic acid, having only a low solvent capacity for lignin; as a consequence of this treatment, lignin which is present in the product will be converted into a lignin derivative that has an increased sealability in the fatty acid and can be removed quantitatively by extraction from the lignocel-lulosic material. Purified pulp can thus be obtained with increased processing efficiency and without most pollution problems of prior art processing methods because the fatty acid used as the main constituent of the processing liquid in all stages of pulp production can be circulated coun-ter-currently through the stages of the process with puri-fication of the acid for recirculation only after its use in the digestion step where the normal starting materials of pulp production, i.e. wood or annual plants, are treated according to the acetosolve process at ambient pressure and temperatures of below 120° to form a raw pulp product.

Granted: 1993-11-30
Abstract: MODULAR CROSSBAR INTERCONNECTION NETWORK  FOR DATA TRANSACTIONS BETWEEN SYSTEM   UNITS IN A MULTI-PROCESSOR SYSTEM                       ABSTRACT      For efficiently handling data transactions between various system units (CPUs, I/O units and main memory units) in a multi-processor system, the system units are linked via a plurality of expandable crossbar modules, each providing a set of interconnections or well-defined mappings between the sets of input and output nodes, with each output being defined in terms of only one input.  In addition to the nodes provided at the input and output sections, each crossbar module is also provided with discrete input and output expansion ports through which the module may be linked to other identically configured crossbar modules when additional nodes are to be integrated into the system.  The expansion ports allow serial linking of crossbar modules so as to establish a connection between source and destination nodes which are spread across different crossbar modules.  The serially-linked expansion ports realize direct mapping between all system nodes in the form of a two-stage network; the basic crossbar design remains the same and there is no need for the problematic redesign of crossbar modules for accommodating added data transfer nodes.  The modular crossbar design is particularly adapted for use with different system configurations having different numbers of communication nodes and permits a system to be upgraded by adding communication nodes by using additional identically configured crossbar modules.

Abstract: A method of disintegrating plastics and/or rubber material, such as the plastics and/or rubber casings of metal cores, for the purpose of recovering the metal from scrap cables for example. The material to be disintegrated is cooled to a temperature at which it becomes brittle. The embrittled material is then subjected in at least one station to mechanical oscillations which cause the material to disintegrate. The oscillations suitably have a frequency in excess of 30 Hz and an amplitude of about 2-3 mm. The oscillations can be imparted with the aid of a vibratory device with which the embrittled material is brought into contact.

Abstract: An optical fibre ribbon structure suitable for use in an optical cable or other application where there is a risk that optical fibres will be subjected to a tensile force comprises a plurality of optical fibres (1) and flexible reinforcing elements (2) of resilient material arranged side by side and embedded in an elongate plastics body (3). Each resilient reinforcing element (2) is set in such a form that the ribbon structure follows a path of smoothly curved undulations (4) whose axes of curvature lie parallel to one another and normal to the longitudinal axis of the ribbon structure. When the undulating ribbon structure is subjected to a tensile force, the ribbon structure straightens in a lengthwise direction against the action of the resilient reinforcing elements thereby reducing the tensile force otherwise applied to the optical fibres (1). When the tensile force is removed, the ribbon structure returns towards its original undulating form.
