Abstract: The present invention relates to a novel process for the preparation of high-purity chemicals with an extremely low particle count, such as ammonia gas, hydrogen fluoride and hydrogen chloride, which are also used as aqueous solutions in semiconductor technology the corrosive gas is enriched with an absorbent which is miscible with the gas and in which impurities present in the gas are soluble, and the gas is subsequently subjected to membrane filtration.

Abstract: A lightweight, laminated structural component, such as a skin section for an aircraft fuselage, is constructed of at least two sheet metal plies that are adhesively bonded to each other. One ply is an uninterrupted ply. The other ply is a lattice with open fields surrounded by strip shaped lands which fortify load exposed areas of the lamination. The open fields of the lattice make mechanical or chemical pocketing operations unnecessary. By shaping and positioning the strip shaped lands including struts in accordance with load patterns to which an aircraft skin is exposed in use, the skin characteristics can be tailored as required.

Abstract: In a metal layer material comprising at least two metal sheets, each sheet has a thickness of less than 1.5 mm. Between the sheets, a plastic layer is disposed, which is bonded to the metal sheets. The plastic layer comprises a plastic material and basalt fibers, and the basalt fibers have a modulus of elasticity exceeding 50 GPa. The basalt fibers may constitute 35-75% of the volume of the plastic layer. and may be comprised of 35-55 weight % of SiO2, 10-25 weight % of Al2O3, and 3-10 weight % of MgO. In aerospace applications and other applications requiring good specific strength, stiffness and damage tolerance, the metal sheets may be made of a metal having a tensile strength exceeding 0.20 GPa.

Abstract: In piezoceramic multilayer actuators, the head region and the foot region consist of inactive, that is to say electrode-free, piezoceramic layers. Due to the arrangement of the metallic electrodes and the layers of the piezoceramic materials, the shrinkage of the piezoceramic material, in particular in the passive head region and foot region, is influenced during the sintering process and can cause the formation of cracks. Different expansion behavior of the active and of the passive region during operation also lead to stresses which favor crack formation, in particular at the boundary between both regions. According to the invention, it is therefore proposed that a transition region (11), whose shrinkage and expansion behavior lies between the shrinkage and expansion behavior of the active region (10) and the shrinkage and expansion behavior of an inactive region (8, 9) which are electrode free, adjoins the active region (10) up to the inactive head region (8) and up to the inactive foot region (9).

Abstract: A rivet splice that holds an upper and a lower sheet metal end portion together includes at least one row (6) of rivets that is subject to dynamic loads and a further row (7) of rivets that holds the sheet metal end portions together so that a limited sliding motion between the sheet metal end portions is possible. The further row (7) of rivets is positioned between an end edge (4A) of an upper sheet metal end portion and the at least one row (6) of rivets. The limited sliding motion provides a load relief of the at least one row of rivets thereby reducing the starting of cracks at the walls of the rivet holes and impeding the spreading of cracks.

Abstract: An additional fiber reinforced layer reduces crack propagation in a lightweight structure of an outer skin adhesively bonded to a reinforcing frame. For this purpose the additional fiber reinforced layer is interposed between the outer skin and the frame and adhesively bonded to the outer skin and to the frame. The additional layer has reinforcing fibers extending in parallel to each other or the reinforcing fibers are woven into a fabric embedded in a synthetic adhesive bonding material. The embedding of the parallel fibers or of the fiber fabric in the bonding material is performed either prior to the bonding or during the bonding of the additional layer to the outer skin and to the reinforcing frame.

Abstract: An outer skin, for example of an aircraft body, is supported by a frame of longitudinal girders and circumferential ribs interconnecting the girders. Additionally, the outer skin is strengthened by reinforcing strips adhesively bonded to the outer skin between the ribs and girders. The reinforcing strips are made of material that is damage tolerant, for example high strength aluminum alloys and fiber composite materials are suitable for making the reinforcing strips. These reinforcing strips may extend in parallel to the stringers and/or the ribs and preferably form a lattice work. The reinforcing strips need not cross each other at right angles but should cross a crack propagation direction in the outer skin.

Abstract: The invention relates to a biocidal composition which can be added to materials which can be attacked by harmful micro-organisms, containing pyrithione as a biocidal active ingredient. The biocidal composition is characterised in that it contains 2-alkyl isothiazoline-3-one as another biocidally active ingredient. The active ingredients of the biocidal composition behave synergistically and are ideally suitable for controlling bacteria, fungus and algae.

Abstract: A metallic structural component for an aircraft includes stiffening profile members integrally formed or connected onto a skin sheet. Each stiffening profile member includes a first part integrally connected to the skin sheet, and a second part non-integrally connected to the first part so as to form an internal boundary surface within the multi-part stiffening profile member. If a crack forms in the skin sheet and propagates into the first part of the stiffening profile member, the internal boundary surface resists the further propagation of the crack past this boundary surface. The crack propagation resistance is improved, the remaining strength of the structural component after formation of a crack is increased, and the overall structural component is light in weight. The outer contour of the stiffening profile member is not affected by the provision of the separate first and second parts or the internal boundary surface therebetween.
