Abstract: Embodiments of the present application relate to illumination devices using luminescent nanostructures. An illumination device includes a first conductive layer, a second conductive layer, a hole transport layer, an electron transport layer and a material layer that includes a plurality of luminescent nanostructures. The hole transport layer and the electron transport layer are each disposed between the first conductive layer and the second conductive layer. The material layer is disposed between the hole transport layer and the electron transport layer and includes one or more discontinuities in its thickness such that the hole transport layer and the electron transport layer contact each other at the one or more discontinuities. Resonant energy transfer occurs between the luminescent nanostructures and excitons at the discontinuities.

Abstract: An aroma granulate mill for dispensing ground aroma granulate, particularly a spice mill for dispensation of ground spices, such as salt and pepper, comprising a container for accepting unground, coarse aroma granulate, an element provided at the container having a dispensation opening for dispensing ground, fine-grained aroma granulate, and a grinder arranged upstream to the dispensation opening for milling the unground, coarse aroma granulate into ground, fine-grained aroma granulate is provided. The element includes the dispensation opening having a concave collar, which forms a cavity open towards the outside, which has a circumferential side wall and comprises at least one section recessed in reference to the circumferential side wall in the direction towards the container, in which the dispensation opening is arranged, with the circumferential side wall defining an opening, with its area being smaller than the cross-section of the opening of the cavity at its widest section.

Abstract: A device is described to encapsulate solid flavoring substances, particularly tea or coffee, added to a liquid, particularly water, with a wing-shaped rotary slider supported rotational about a rotary axis between an initial position and an end position, which in its end position limits a space accepting the solid flavoring substances, with the device being embodied for the installation in a container with its top showing an opening to fill in or discharge the liquid, which can be closed by a lid, which for closing and opening the container opening is subjected to a rotary motion, characterized in that the rotary slider comprises at least one engagement means by which the rotary slider can be made to engage the lid at least during the rotary motion in order to close the container opening and can be rotated into its end position.

Abstract: Proposed is a device for encasing flavoring solids (T), in particular tea material or coffee, that are put into a liquid, in particular water, with a vane (20′) movable between an initial and a final position, which vane in its final position bounds a space (8″) that holds the flavoring solids (T), the vane being designed as a rotatable vane (20′) that is supported so as to be rotatable around a rotational axis.

Abstract: The invention concerns a permanent filter for the preparation of tea in pots or cups, consisting of a filter housing with an upper, ring shaped rim (1) and a fluid permeable straining fabric (3). The special feature of the invention consists in the fact that provision is made in the upper rim (1) for one or more openings (5) for receiving a tab (7) of a lid (6).
