摘要:
Formulations for dressing, dressing layers, dressed textile fibers and textile fabrics, and methods for dressing textile fibers and textile fabrics are provided. The textiles can receive, a plurality of times, active substances, or active ingredients, which can be deposited in a isotropic manner to the surrounding medium or in an anisotropic manner in a directly adjacent layer by means of a locally oriented material flow. The dressing layers are characterized by their ability to swell and to receive active substances. Polymer layers form nano pockets during swelling which can receive one or several guest molecules. The active substances can be deposited when the loaded textiles are worn and absorbed by the skin of the wearer, either cutaneously or percutaneously, to produce the desired effect.

Methods for coating fibers and material to achieve particular properties such as water repellency, oil repellency and self-cleaning, are provided. These properties are achieved by pre-treating the fibers or material and subsequently coating with prepolymers and nanoparticles. The prepolymers are partly substituted with hydrocarbon groups or fluorocarbon groups. The nanoparticles may have surfaces treated with hydrocarbons or fluorocarbons. The prepolymers are fixed and hardened by irradiation with light of a wavelength in the UV or visible regions.

The invention relates to a method for oxidizing substances contained in sewage, a nozzle system, and a plant for carrying out this method. The method is characterized in that three radical chain circuits are superimposed, thus producing a continuous reaction chain which is maintained by incorporating a radical starter, a catalyst and oxygen into the sewage flow. The reaction is characterized in that the reaction partners are brought together via a nozzle system which creates unsteady flowing conditions. To reduce operational costs, the sewage is fed by the nozzle system to the autothermic reactor via a heat exchanger which is heated by the treated sewage flow. The method is characterized by its flexibility in treating different kinds of sewage flow of different concentrations. The advantages are, above all, the following: reduced sludge production, high biocompatibility of the residues to be transported, and low consumption of chemical substances. These advantages, combined with the autothermic nature of the reaction and the high degree of efficiency, result in an economic procedure for waste disposal.

An anesthesia system for providing a breathing gas enriched with anesthetic has an anesthesia apparatus (2) and at least one anesthetic dispensing device (3), which is detachably coupled with the anesthesia apparatus. A fluid connection (7, 8, 9) is provided between the anesthesia apparatus and the dispensing device, which is designed to send anesthetic from the dispensing device into the anesthesia apparatus. At least one optical interface is provided between the anesthesia apparatus and the dispensing device. At least one display device is provided in the dispensing device. The optical interface has at least one light source (10), which is provided in the anesthesia apparatus, and at least one fiber optic light guide (20), which is provided in the anesthetic dispensing device (3). The light fed by the light source (10) into the fiber optic light guide is sent to the display device to directly or indirectly light the display device.
摘要:
Eccentric gearing (10) for displacing two parts positioned in a manner that enables them to move relative to one another. The eccentric gearing includes a gearing housing (12), an eccentric element (20), which is driven by a rotary drive (28) and on which an eccentric gear (30) is rotationally mounted, and it includes an output element (40), which interacts with the eccentric gear (30) by meshing therewith in sections. The eccentric gear (30) is actively connected to a coupling element (54) placed inside a recess (67) of a fastening flange (60) that enables the eccentric gearing (10) to be fixed on one of the two parts (8, 9).

摘要:
A multifunctional, responsive functional layer on a substrate, such as textiles, paper and plastic materials, includes at least one first and a second functional component, of which at least one of the second functional components meets the chemical-functional and constitutional specification for responsive behavior and thereby can be reversibly switched by an outer stimulus. The first and second functional components differ with respect to the intrinsically specified properties thereof and are matched to each other, wherein at least one of the functional components on the substrate is present as a physical-chemical compound. Methods are disclosed for producing the multifunctional, responsive functional layer, which enable the combination of functions, such as moisture management, soil release, antistatic, hydrophobicity, hydrophilicity, oleophobicity, controlled release, and conductivity.
摘要:
An anti-static multi-functional layer is disclosed for finishing and coating substrates and for introducing the polymer/particle composites contained in the multi-functional layer into substrates. The layer can include a polymer matrix containing at least one polymer compound and at least one non-metallic particle type and/or a metallically conductive particle type in combination with a metallic electrolyte. The particle combination can be encapsulated by a coating matrix, thus forming a multi-functional layer. A virtually continual discharge of the static charge that occurs can be guaranteed by the electrochemical reaction taking place in the layer and produces a charge neutralisation. Methods are disclosed in which the anti-static multi-functional layer is used, for example to finish textiles, to coat plastic film and coverings and to introduce the polymer/particle composites contained in the multi-functional layer into a plastic.
摘要:
The invention provides a method of reversibly storing hydrogen at industrially practicable temperature and pressure conditions. A stable hydrogen storage hydride is mixed with a destabilizing hydride. The stable hydride is capable of releasing hydrogen at a first energy level. When the stable hydride is in the presence of the destabilizing hydride, the stable hydride releases hydrogen at a second energy level. The second energy level is significantly reduced from the first energy level.
