Abstract:
According to the invention, a process for the preparation of triphendioxazines symmetrically or asymmetrically amidated on both sides comprises reducing a triphendioxazine chromophore, which is optionally already amidated on one side, to give the leuco form and amidating and re-oxidizing the leuco form. Products amidated on both sides are obtained in this manner with a high yield and product quality. Novel triphendioxazine dyestuffs are furthermore prepared in this manner.

Abstract:
The invention relates to a multilayered film element (1) comprising a first component, more particularly an RFID antenna in the form of a multilayered film element, and to a method for fixing a second component on a film element (1) of this type. The film element (1) has a dielectric layer (10) having a front side (10V) and a rear side (10R). The film element (1) has a layer (11, 12) forming a first component, and at least one component contact area (23, 24) arranged on the front side (10V) and connected to the first component. The film element (1) has at least one thermode contact layer (30) which is arranged on the dielectric layer (10) and which, as seen perpendicularly to the dielectric layer (10), is arranged in the region of the at least one component contact area (23, 24). The thermode contact layer (30) has a thermode contact area (32) on a side facing away from the dielectric layer (10), said thermode contact area forming an outer surface of the film element (1).
Abstract:
An air conditioning system for an aircraft for the individual air conditioning of regions of a cabin of an aircraft includes a central air conditioning device, which provides a pressurized and temperature-controlled central air flow. A part of the central air flow is supplied to a first cabin region. Another part of the central air flow is heated in a heating device or cooled in a cooling device and supplied to another cabin region. Water evaporates in the cooling device, in order to cool the air flow to be supplied to the cabin region.

Abstract:
A multilayer film element and a method for producing the same. The multilayer film element includes a flexible dielectric carrier layer having a layer thickness of less than 800 μm and has a first electrically conductive layer, in which a first coil-shaped conductor track is shaped in a first region of the film element, and a second electrically conductive layer, in which a second coil-shaped conductor track is shaped in the first region. The dielectric carrier layer is arranged between the first and second electrically conductive layers, and the first and second conductor tracks overlap at least in regions and are coupled to one another to form an antenna structure.
Abstract:
The invention pertains to an inerting system for an aircraft featuring at least one air separation module with at least one air inlet, a first air outlet and a second air outlet. The air separation module is designed for splitting an input air flow into a first air flow and a second air flow, wherein the first air flow is enriched with oxygen in comparison with the input air flow and discharged at the first air outlet and the second air flow is enriched with nitrogen in comparison with the input air flow and discharged at the second air outlet. In comparison with known inerting systems, the inerting system according to the invention is characterized in that the air inlet can be connected to an air extraction point in an air processing system and the inerting system is designed for routing the first air flow into a cabin to be air-conditioned.
