GRID-LIKE FRACTAL DISTRIBUTOR OR COLLECTOR ELEMENT
A distributor element comprising: at least two fractal plates each defining a level below an adjacent fractal plate, an uppermost fractal plate comprising a first number of first openings, each of the first openings surrounded at a lower side by one of a plurality of first walls and, in the first level between the first walls, one or more first hollow spaces defining one or more first fluid paths, a second fractal plate comprising a second number of second openings, each of the second openings surrounded at a lower side by one of a plurality of second walls and, in the second level between the second walls, one or more second hollow spaces defining one or more second fluid paths, the second number being higher than the first number, and each of the first fluid paths and each of the second fluid paths having substantially a same length.
A device is provided having a structure for conducting a first fluid, the structure having in addition an interface for conducting a second fluid. The first fluid can be brought into contact with the second fluid at the interface of the structure. A flow interrupter (120.0) for interrupting a flow of the second fluid is situated at the interface of the structure.
The present invention relates to a distributor element and/or collector element for uniformly distributing a first fluid, such as liquid, on a cross-sectional plane, such as on a cross-sectional plane of a mass transfer column, wherein a second main fluid, such as gas, flows in co-current flow and/or in counter-current flow with regard to the first fluid through the distributor element, wherein the distributor element comprises at least two levels separated from each other by fractal plates comprising openings and apertures, wherein each level comprises channels to be flowed through by the second main fluid and between the channels one or more flow path(s), through which the first fluid may flow, wherein the number of openings increases from the uppermost fractal plate to the lowest fractal plate, wherein the channels to be flowed through by the second main fluid are fluid-tightly separated by the walls from all of the one or more hollow spaces defining the fluid paths, through which the first fluid may flow, and wherein each of the fluid paths has at least substantially the same length, wherein substantially the same length means that each of the fluid paths of the level does not vary more in the length compared to the length of any other fluid path of the same level by more than 20%.

The invention relates to a method for manufacturing molded articles consisting of at least one molded article layer, said method comprising the steps of a) putting a layer support in place for accommodating at least one molded article layer; b) applying a molded article layer to a printing plate using a shaping tool; c) positioning the printing plate and the layer support or a previously produced molded article layer relative to one another; d) curing the molded article layer such that said layer becomes a previously molded article layer, and transferring the molded article layer; e) if necessary, putting the printing plate in place for accommodating additional molded article layers and repeating steps b) to d). The invention further relates to an apparatus for carrying out the disclosed method as well as to the use of molded articles obtained thereby.
