Abstract: A module may include a receiving element in the form of a bearing frame or a covering hood for arrangement on a cylinder head of an internal combustion engine. The module may further include a camshaft that is rotatably mounted on the receiving element and projects from the receiving element to hold a camshaft wheel. The module can be prefabricated for direct mounting on the cylinder head. In the prefabrication process, the camshaft may be locked against rotation by an externally accessible securing part in an angular position for acting on valves. The securing part may extend through a first aperture in the camshaft wheel and through or into a receptacle of the receiving element. After mounting the module on the cylinder head, the securing part can be removed.

Abstract: An airplane wing has a lower wing cover, an upper wing cover and a wing spar. A first end portion of the wing spar is welded to the lower wing cover and/or a second end portion of the wing spar is welded to the upper wing cover.

Abstract: The invention concerns a method of dimensioning and producing stiffened structural components (4) comprising at least one shell component (6) and at least one stiffening component (8) which can be connected thereto, in which the shell component (6) and the at least one stiffening component (8) is dimensioned on the assumption of intactness of the at least one stiffening component and having regard to a predetermined safety factor and/or a predetermined structural inspection interval in which a predetermined maximum crack progression in the shell component is not to be exceeded and/or the strength of the structural component is not to fall below a predetermined minimum residual strength, and in which the at least one stiffening element (8) of the structural component dimensioned by this method is equipped with at least one structural condition sensor (30) for detecting intactness; as well as the use of structural condition sensors in an aircraft, in particular a passenger aircraft.

Abstract: A fiber reinforced strip is adhesively bonded to an outwardly facing surface of a reinforcing frame and to an inwardly facing outer skin surface. Such a strip position reduces crack propagation in a lightweight structure particularly in the outer skin adhesively bonded to the reinforcing frame through the strip. For this purpose the fiber reinforced strip is interposed between the outer skin and the frame and adhesively bonded to the outer skin and to the frame. The strip 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 strip to the outer skin and to the reinforcing frame.

Abstract: The process of making synthetic silica glass occurs in a combustion chamber of a muffle furnace. It includes producing a gas flow containing a fuel, an oxidizer, and a silicon compound that is converted by flame hydrolysis and/or by chemical oxidation to SiO2 particles, and depositing them on a target to form a roll-shaped silica glass body. The combustion chamber is provided with a gas inlet and a gas outlet arranged at opposite ends of the combustion chamber, which widens from the inlet to the outlet. The gas flow is produced by a central nozzle for the silicon compound, a first concentric ring-shaped nozzle for the oxidizer, and a second concentric ring-shaped nozzle for the fuel. The process is characterized by a ratio of areas of ring gaps of the ring-shaped nozzles of from 1:4 to 1:6.1. The apparatus for the process is also part of the invention.

Abstract: The invention relates to a coating material for protection against microorganism invasion on surfaces which are exposed to the effects of damp or water. The coating material has either a pH-value of at least 11.0 or is provide with a base material for the coating whereby the pH-value is at least 11. The coating material is characterized in that it contains a biocide which bonds to solid particles in a carrier material and is released in a delayed manner therefrom.

Abstract: An outer skin of an aircraft body is supported by a frame of longitudinal stringers and circumferential ribs or frame elements interconnecting the stringers. Additionally, the outer skin is strengthened by a reinforcing strip formation adhesively bonded to the inwardly facing surface of the outer skin between the ribs and stringers. The reinforcing strips are made of a material that is damage tolerant, for example high strength aluminum alloys and fiber composite materials are suitable for making the reinforcing strip formation. The reinforcing strips of the strip formation 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: A metallic layer material includes 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: An improved process and catalyst system for the isomerization of halothiophenes. More particularly, an improved process for the isomerization of 2-halothiopehenes to 3-halothiophenes by reacting a 2-halothiophene with a catalyst and in the presence of a base. The addition of a base additive to the acidic zeolite catalyst allows the desired isomerization reaction to take place while suppressing side-reactions that result in the decomposition of thiophene rings. The catalyst lifetime is thus increased and the amount of catalyst needed for the reaction is reduced, lowering cost.
