  • Patent number: 11937622
    Abstract: The present invention relates primarily to a method for obtaining a volatile fraction from a juice and/or an alcohol-containing beverage, comprising or consisting of the following steps: (a) distilling a mixture of substances from the juice and/or the alcohol-containing beverage, wherein the distillation is performed by a spinning cone column; (b) contacting the mixture of substances from step (a) with a sorbent to obtain a loaded sorbent; and (c) contacting the loaded sorbent from step (b) with a liquid desorbent to obtain the volatile fraction, wherein desired ingredients of the volatile fraction are concentrated as compared to the juice and/or alcohol-containing beverage such that an addition of 0.1% by mass or less of the volatile fraction to any food preparation produces a perceptible odor impression and/or taste impression in a test subject.

  • Patent number: 11239170
    Abstract: The present invention relates to a module that has a lower component of a module (1) having a material (3) in which at least one first structural element (4) is embedded, and an upper component of a module (2) having a material (3) in which at least a second component (16) is embedded. The upper component of the module (2) and the lower component of the module (1) are stacked, with the lower and the upper component of the module (2) being electrically connected and mechanically linked to each other. In addition, the present invention relates to a simple and cost-effective process for the production of a variety of modules. The invention makes it possible for the modules to be miniaturized with respect to surface and height and/or makes it possible to achieve greater integration by 3D packaging.

  • Patent number: 10021816
    Abstract: A three-dimensional arrangement for a power converter device, e.g., an inverter or a rectifier, is provided. The switching elements, activation electronics, the load connections of the power converter device are arranged on a carrier device in such a way that defines especially short conduction paths. The components of the power converter device (e.g., all required components), such as switching elements, control electronics, and load connections, are arranged on a common carrier device. The carrier device is simultaneously used as a cooling device for the entire switching device. The power converter device may thereby achieve particularly efficient performance.
