A woven fabric includes warp threads or wires and includes weft wires, wherein, the woven fabric includes an offset weft wire. The offset is particularly suitable for fastening objects separate from the woven fabric. A method uses the woven fabric as a facade hanging by using the woven fabric as a base structure for bearing an object separate from the woven fabric. The object is borne on the offset separate from the woven fabric.

An apparatus for treating a medical liquid includes a treatment machine having a coupling surface and a flexible mat arranged on the coupling surface, with a cassette made of a hard part having liquid-conducting passages therein which are covered by a flexible film that is couplable to the coupling surface of the treatment machine via the flexible mat. The apparatus includes an element for monitoring a fault-free coupling to the cassette at the coupling surface by determining a difference of the pressure between the cassette and the flexible mat and the pressure between the flexible mat and the coupling surface. A method for checking the leak tightness of the fault-free coupling employs the apparatus.

An optoelectronic inclination sensor determines the inclination of a reference plane relative to the horizontal. A sensor body has a liquid layer, the free surface of which represents a horizon that can be inclined relative to the reference plane, forming an optical boundary to the adjacent medium. A light source disposed below the liquid layer emits a light beam onto the boundary. An optical sensor surface below the liquid layer detects the light beam reflected by the boundary. An analysis unit determines the inclination of the reference plane as a function of the amount of light received by the sensor surface. A deflecting element for deflecting or initially totally reflecting the beam is disposed between the source and the liquid layer. The beam is inclined as a result of said deflection or initial total reflection. A second total reflection occurs at the boundary in both the inclined and non-inclined orientation.

In a method for a model-based determination of a temperature distribution of an exhaust gas post-treatment unit, a differentiation is made between steady operating states and non-steady operating states by taking into account the axial and the radial temperature distribution, and, on the basis of virtual segmentation of the post-treatment unit, in particular the radial heat transfer to the surroundings is taken into account in the model-based determination for steady operating states, and for non-steady operating states the heat transfer from the exhaust gas which flows axially through the post-treatment unit to the segments is taken into account by a heat transfer coefficient k.

The present invention relates to a device and a method for blood treatment in a single-needle operating mode. The blood treatment device has an extracorporeal blood circuit comprising a blood supply line leading to the inlet of a blood treatment unit and a blood return line leading away from the outlet of the blood treatment unit. Blood collecting means, for example a blood collecting container, is provided in the blood return line, said means being connected to means for storing gas, for example an air reservoir, by a flow line. The flow connection comprises two line branches, one branch being used to transfer gas from the air reservoir into the blood collecting container and the other branch being used to transfer gas from the blood collecting container into the air reservoir. The connection branch for transferring gas from the air store into the blood collecting container contains means for compressing air, for example a compressor. The device according to the present invention may be operated in such a way that the filling level of the means for collecting blood can be determined as precisely as possible.

The invention relates to a method and a device for sintering objects by means of time-resolved detection of two- or three-dimensional surface profiles and, optionally, by means of temperature measurement in a high temperature furnace on the basis of optical measurement methods. During sintering, each surface point on an object can be measured for its position and, optionally, its temperature, and a change can be determined by successive measurements. The measured change additionally permits control of the sintering regime.The method comprises the steps of: placing an object 4 into a high temperature furnace 5; heating the furnace 5; generating a two- or three-dimensional surface profile at least of a subregion of the object 4 by: irradiating the object 4 with light from a light source 2a; detecting the light scattered by the object 4 with the aid of a detector 2b; determining the geometric surface profile from the detected light.

The present invention relates to an apparatus for treating a medical liquid which includes a treatment machine having a coupling surface, with a cassette made of a hard part having liquid-conducting passages which are covered by a flexible film being able to be coupled to the coupling surface of the treatment machine. The invention furthermore relates to a corresponding medical cassette. In accordance with the invention, an air-free coupling of the flexible film of the cassette to the treatment machine is ensured in that air can be sucked out areally along a plane between the flexible film and the coupling surface during the coupling process and/or with a coupled cassette. The invention equally includes a method for coupling the cassette and a method for checking the leaktightness of the cassette via the vacuum control of the air suction.
