Abstract: The invention relates to a device for membrane filtration and for the removal of micropollutants from liquids by way of a reactive substance, the device comprising a reaction chamber and at least one port for supplying and/or discharging the reactive substance to and/or from the reaction chamber, such that the micropollutants are able to react with the reactive substance in the reaction chamber and/or may be removed from a liquid, and the reaction chamber comprising a first membrane and a second membrane, the first membrane being designed as an inlet into the reaction chamber and the second membrane being designed as an outlet from the reaction chamber, such that the liquid to be treated is able to be filtered by the first membrane and to flow into the reaction chamber, the liquid treated with the reactive substance in the reaction chamber is able to be filtered by the second membrane and to flow out of the reaction chamber, and the outflow of treated liquid is substantially free from micropollutants.

Abstract: The invention relates to a filter element (1) comprising a drainage element (2) which is arranged between two filter membranes (3). According to the invention, said drainage element (2) is made of a non-woven filtering material which is arranged in a laminated manner between the filter membranes (3) respectively by means of an adhesive non-woven material (4). The invention also relates to a method for producing a filter element (1), a drainage element (2) made from a non-woven filtering material being laminated between two filter membranes (3). An adhesive non-woven material (4) is arranged between the drainage element (2) and each filter membrane (3), then lamination takes place due to the thermal effect under pressure.

Abstract: A filter element for cleaning liquids, having a stack of at least two filter membrane pockets, which are substantially flat and include a flexible, liquid-permeable filter material for retaining waste particles and/or microbes, wherein each filter membrane pocket has a substantially polygonal shape with at least three corners and a corresponding number of edges, wherein the filter membrane pockets are stacked with a defined distance and aligned with each other, wherein aligned corners of the filter membrane pockets are embedded in a casting covering only part of the adjacent edges such that the casting for each corner is spaced from the castings of the neighboring corners.

Abstract: A damper for the elimination or reduction of flexural vibrations in rotating shafts, consisting essentially of a damper mass surrounding the shaft with a radial spacing and of a support member, whereby both parts are connected by way of at least one spring element; the support member is thereby rotatably supported on the shaft and the flexural vibration damper is operatively connected with a fixed part.

Abstract: Apparatus and method are disclosed for inserting an additive type thread along a surface area of a braided fabric. Base material containing bobbins are guided about the base material bobbin path, whereas bobbins containing the desired additive thread are only permitted to revolve around a portion of the base material bobbin path corresponding to the fabric surface. The base material containing bobbins and the additive thread containing bobbins are provided with different types of feet; the feet of the base material bobbins cooperating with stationary switch means located along the bobbin path to permit rotation of the base material bobbins about the entire bobbin path. In contrast, the feet of the additive type bobbins cooperate with the same stationary switch means in such manner that rotation of the additive thread containing bobbins is limited to a certain specified portion of the bobbin path; the portion corresponding to the desired fabric surface area.
