Abstract: An aircraft having at least two separate aircraft fuselages is provided. The aircraft includes a first wing arrangement with at least two non-connected wing sections, and a second wing. In each case the wing sections of the first wing arrangement extend from the outside of an aircraft fuselage towards the outside. The second wing is arranged between insides of the at least two aircraft fuselages. Connecting regions of the first wing arrangement and of the second wing are arranged so as to be offset relative to each other at least on an X-Z-plane of an aircraft-fixed coordinate system. Consequently, the first wing arrangement and the second wing do not influence each other as a result of downwash, and in addition it is possible to do without horizontal stabilizer units that generate downthrust.

Abstract: A binding fiber having, as at least one first thermoplastic component, a copolyamide which has a relative viscosity of at least 1.50 (measured at 0.5% in m-cresol at 25° C.), a MVR of maximum 20 cm3/10 min at 190° C. and 2.16 kg load, a hydrophobicity of less than 7.2, a melting temperature lower than 105° C. in the water saturated condition and a higher melting temperature in the dry condition. The binding fiber can, on the one hand, be activated with hot steam at approximately ambient pressure during the manufacture of flat materials containing natural fibers, such as paper, cardboard, wood fiber boards, or fiber mats. The finished flat material can, on the other hand, be subjected to higher temperatures, and the copolyamide develops good bonding with respect to the cellulose fibers normally used in the indicated flat materials.

Abstract: The invention relates to a press felt for use in the press section of a paper machine. Said felt comprises a nonwoven layer lying on one of its surfaces, the surface of said layer being connected and fixed to the felt by a thermoplastic binding material. According to the invention, the surface of the nonwoven layer is smoothed by the application of pressure from a smooth surface during the cooling of said layer surface from a temperature in excess of the melting temperature of the thermoplastic binding material to a temperature below the melting temperature. To manufacture the press felt, an untreated press felt, which contains the nonwoven layer and the thermoplastic binding agent is first produced, the thermoplastic binding agent being distributed in the nonwoven layer in the form of thermoplastic adhesive fibres and/or a thermoplastic adhesive component of bicomponent fibres.

Abstract: A device for adjusting the lift characteristics of an aircraft with a high lift device that is movably attachable to a wing element and that includes at least one slot covering device, where the at least one slot covering device, is movably attachable to the wing element. The slot covering device is designed to regulate the size of a slot between the wing element and the high lift device.

Abstract: A rudder of a commercial aircraft is provided that is divided along its longitudinal direction in at least one region and the parts of the rudder can be spread against the air flow surrounding the aircraft by means of an actuator in order to decelerate the aircraft.

Abstract: The present invention relates to a novel STR typing strategy, which allows the simultaneous amplification and subsequent analysis of several (e.g. eleven) polymorphic systems with amplicon sizes of less than 270 bp. Thereby, after a PCR amplification the multiplex reaction is divided into two sets of STR multiplexes and analyzed separately. This multiplex system was particularly developed and tested for use in forensic investigations, where only limited amounts of DNA or only highly degraded DNA is available, for example, when the DNA is isolated from the roots of telogen hair.

Abstract: A brake flap is provided for an aircraft, which brake flap, for the purpose of delaying the aircraft, can be set at an angle relative to the airstream flowing around it. The flap comprises a free edge which when set at an angle is spaced apart from the exterior skin of the aircraft, and generates an edge vortex in the airstream flowing around said aircraft. The free edge comprises a number of individual edge sections that divide the edge vortex into a number of partial vortices.

Abstract: A dimensionally stable and fireproof acoustic panel includes an underlying panel covered on one or both sides by a cover panel. The underlying panel can be produced with a cover layer on the interior side thereof. The cover layer is composed of two layers, a coarse-pored stabilizing intermediate layer which in turn is covered by a second, fine-pored outer layer, both of which are bonded to one another and to the underlying panel by a matrix of adhesive material.

Abstract: A sound-absorbing building panel for lining of the inside walls and ceilings, in particular ceiling tile, consists of a carrier panel to be arranged spaced from a wall, which carrier panel is advantageously a perforated sheet metal and to which on at least one side a sound-absorbing, microporous layer is applied. Such a building panel, which does not require an insulation layer as a backing and can, moreover, be manufactured inexpensively, has a sound-absorbing layer of granules which are surrounded on all sides by an adhesive coating. The granules are essentially designed ball-shaped and are adhesively connected together at point-like connections and to the carrier panel. The granules also have a diameter between 0.1 to 0.9 times of the hole diameter of the carrier panel.

Abstract: A process for making injection molded articles having a substantially smooth outer surface and a foamed core by injecting a molten thermoplastic into a mold, and, when the outer surface has formed, injecting a gas under pressure into the mold whereby a limited amount of molten material flows back into the injection unit to create a hollow space in the core of the melt, and releasing the gas pressure to allow the core to foam.
