A device and a method are described for feeding a material layer onto a construction platform, or onto at least one material layer located on the construction platform, for producing an object, which is mounted to linearly move relative to a material reservoir and the construction platform along a motion plane. A circulating band is stretched around at least two molded bodies and contacts the molded bodies at least in segments. A drive circulates the band around the at least two bodies. The band has a band segment which can be fixedly in position relative to at least one body in the longitudinal section around the at least two molded bodies. At least the segments contact the material stored in the material reservoir during the linear motion from the material reservoir to the construction platform so that at least a part of the material is stripped off from the material reservoir and is applied as the material layer to the construction platform to compress the material layer.

An assembled honeycomb structure includes at least two prismatic honeycomb segments. An outer cross section of each of the at least two prismatic honeycomb segments perpendicular to a flow direction in an interior of the assembled honeycomb structure is a quadrangle with included angles of one of: (i) about 60&#xb0; and about 120&#xb0;, or (ii) about 60&#xb0;, about 90&#xb0; and about 120&#xb0;.

The casting-mold material designed to manufacture casting molds used in casting high melting-point substances. The casting mold formed from a powder component containing magnesium oxide and aluminum oxide and a liquid component. The powder component additionally contains a calcium aluminate and an alkali fluoride or an earth alkali fluoride and the liquid component contains a polyelectrolyte and a basic component, the latter determining the liquid component pH value between 10 and 14. A fluid slip is prepared by mixing the powder and liquid components and is dried, hardened and sintered to produce a hollow mold.

The invention relates to the area of ceramics and to ceramic multilayer filters, such as used for separating gases. The invention provides ceramic multilayer filters which are more economical to produce. To this end, the inventive ceramic multilayer filters include at least two layers of different particle size, the particle surfaces of all of the ceramic particles being completely or partially perfused with a material and spot and/or surface joints being formed between particles. The invention also provides a method for producing ceramic multilayer filters of this type, according to which slips are produced from at least two ceramic powders of different particle size, the particles of the ceramic powders being perfused with a material or a material in powder form being added to the ceramic slips. One or more layers are formed from the slips and then dried. At least two layers are placed one above the other and/or joined to each other and together are subjected to a temperature increase.

The invention relates to the area of ceramics and to a ceramic flat membrane which is configured as a multi-channel element. The aim of the invention is to provide a ceramic flat membrane with a larger effective membrane surface. To this end, the inventive ceramic flat membrane consists of at least two layers of at least two sub-layers of different porosity, at least one of these layers having a non-planar geometry. The two layers are joined to each other with at least spot joins and integral joins. The invention also provides a method for producing a flat membrane of this type. According to this method, suspensions are produced from at least two ceramic powders of different particle size. Two sub-layers are formed from the suspensions, then dried and joined to form one layer. At least one layer which is embossed and sintered, or unsintered is joined to a non-embossed, similarly embossed, differently embossed or differently structured, sintered or unsintered layer with at least spot joins and integral joins to form a flat membrane.
