Abstract: The invention pertains to an insulation structure for thermally and acoustically insulating an aircraft that features at least one heavy layer, wherein the insulation structure according to the invention is characterized in that the insulation structure comprises an additional absorption layer, in that the heavy layer is perforated at least in certain areas, and in that the perforated area ratio of the heavy layer is adapted in such a way that the heavy layer is essentially transparent to sound for frequencies below a double-wall frequency of the insulation structure. This makes it possible to dampen sound with low frequencies below the double-wall frequency as effectively as possible.

Abstract: A window arrangement is provided for enlarging a window area in an aircraft. The window arrangement includes, but is not limited to at least one first installation element. The at least one first installation element is designed to convey fluids, and furthermore includes, but is not limited to a transparent region which covers a first window region such that light waves in the visible spectrum can be let through.

Abstract: When a fire breaks out, air flows that promote the spread of fire may occur in the region between the load bay and the skin of the aircraft. According to one embodiment of the present invention, a fire barrier is disclosed that allows rapid decompression of the passenger cabin in the normal operating mode of the aircraft and prevents flashovers in case of a fire. In this case, the fire barrier may be arranged at different positions in the intermediate wall space of the aircraft.

Abstract: Use of at least one agent chosen from cyclodextrins and the derivatives thereof as a pearlescent agent, in a composition, for example, a pearlescent cosmetic composition, comprising a physiologically acceptable aqueous medium. Use of at least one agent chosen from cyclodextrins and the derivatives thereof and at least one surfactant in compositions. Pearlescent compositions comprising, a physiologically acceptable aqueous medium, at least one agent chosen from cyclodextrins and the derivatives thereof, at least one surfactant, and at least one conditioning agent; as well as use of at least one agent chosen from cyclodextrins and the derivatives thereof as an agent for suspending an insoluble conditioning agent; wherein the compositions disclosed herein may be used in a form chosen, for example, from rinse-out products, for example, for washing and/or conditioning a keratinous material.

Abstract: The invention relates to a radial blower, with at least one axial air inlet port (1) and with a radial air outlet port (2), consisting of a housing subassembly and of a fan subassembly which comprises an electric motor (3) and a fan wheel (4), the housing subassembly having at least one holding part (5), which is arranged in the region of the axial air inlet port (1) and serves for the supporting reception of a carrying part (6) of a fan subassembly, and two shell parts (71, 72) which are connectable releasably to one another and divide the air inlet port (1) and between which the holding part (5) is fastened in the assembly state. In order to improve the mass/power ratio of a blower of this type, it is proposed that the electric motor (3) of the fan subassembly be an electronically commutated direct current motor.

Abstract: The invention relates to an arrangement for lining the interior of a passenger vehicle such as an airplane including a honeycomb formation of several honeycombs arranged side by side. At its end, the honeycomb body is supported by a cover layer supported above and below the honeycomb formation such that by means of two cover layers glued onto the honeycomb formation, a layer design of the honeycomb paneling is created, which layer design is arranged so as to extend parallel to the outer skin of the aircraft and follow the curvature of the outer skin. The honeycomb formation used is made of paper or aramide honeycombs or of a mixed combination of both honeycomb types; on whose cross section of the honeycomb body a CFK cover layer is positioned to both ends of the honeycomb bodies. As an alternative, further CFK insulation layers are glued onto the outer surface of the respective cover layer supported above and below the honeycomb formation, which cover layers comprise a CFK or GFK.

Abstract: The present invention concerns a method for producing recombinant trypsin from porcine pancreas in Pichia pastoris which is soluble and secreted into the culture medium, whereby expression at pH 3.0-4.0 substantially prevents activation of trypsinogen to ?-trypsin and autolysis of ?-trypsin by ?-trypsin into ?-trypsin and from there into inactive peptides.

Abstract: The present invention relates to an insulation structure for the internal insulation of a vehicle. The insulation structure will contribute to ensuring the fire protection for interior regions of the vehicle from a (conceivable) fire incursion from outside the vehicle environment, so that evacuation of the passengers from the vehicle is made significantly easier. Intended modifications to a typical insulation package will implement an elevation of the fire protection safety for separated interior regions lying proximal to a structure external skin. The insulation structure for the internal insulation of a vehicle comprises an insulation package, which is implemented using an insulation, and a film, which is positioned inside an intermediate space that includes internal paneling and an external skin of the vehicle. The insulation package is implemented homogeneously using a first insulation, whose insulation material is burn-through safe.

Abstract: The present invention provides an aircraft fuselage which comprises a bulletproof layer in at least partial areas, an aircraft fuselage being understood as both a primary fuselage structure of an aircraft, i.e., sheeting and associated frames and stringers, aircraft fuselage insulation, and also cabin internal paneling, which encloses a pressurized cabin on the outside toward the primary fuselage structure. In this way, it may be possible to ensure bulletproof security of the aircraft fuselage and thus prevent danger to passengers and/or flight-relevant systems of the aircraft.
