Abstract: Provided herein are sealing compound-filled plastic caps for sealing of connecting elements in aircraft construction against liquids, wherein these plastic caps function as combined protection against fuel and hydraulic oil, especially that based on tributyl phosphate, and against lightning strikes, and can be produced and applied in an economically viable manner. The plastic cap for sealing of connecting elements in aircraft construction consists predominantly of at least one high-performance polymer having a breakdown resistance of at least 10 kV/mm to DIN IEC 60243, and has been filled with a sealing compound having a high energy absorption capacity and including at least one filler selected from the group consisting of gas- and/or air-filled hollow packings, where the plastic cap and the sealing compound are cohesively bonded to one another. Additionally provided is a method of filling and application of such plastic caps, and a corresponding aircraft.

Abstract: A system and corresponding method for data processing, in particular sensor data processing, includes at least two first modules that generate or capture first data, at least one second module that retrieves the first data from first modules which correspond to first modules of at least one predefined set of first modules, and a third module that processes the first data which were retrieved by the at least one second module. The relevant data captured by a plurality of different data capturing modules, in particular sensors, are made available in a processing module in a fast and reliable manner.

Abstract: The present invention is related to a relational database, stored in a computer memory of a computer device, and a database server comprising such a database, a database management system for managing and working with such a database and a method of storing, retrieving, altering and managing data in such a database.

Abstract: A method of recovering titanium dioxide from a titanium oxide bearing raw material, such as e.g. steel slags rich in TiO2 includes the steps of grinding the titanium dioxide raw material, reacting the particulate raw feed material with sulphuric acid under specified conditions, digesting and filtering the resultant cake material containing titanyl sulphate, hydrolysing the titanyl sulphate and, after washing the hydrolysate, calcining the hydrolysate to produce titanium dioxide.

Abstract: A method of recovering titanium dioxide from a raw material additionally containing aluminium includes the steps of grinding the titanium dioxide raw material, reacting the particulate raw feed material with sulphuric acid under specified conditions, digesting and filtering the resultant cake material containing titanyl sulphate, if present, treating the solution to remove calcium and/or iron, precipitating out the aluminium as aluminium ammonium sulphate, hydrolysing the remaining titanyl sulphate solution and, after washing the hydrolysate, calcining the hydrolysate to produce titanium dioxide.

Abstract: A two-axis rate gyro has two articulation elements arranged sequentially. The first articulation element is connected with a drive shaft of the rate gyro and the second articulation element is connected with a gyro rotor. The two articulation elements are connected together by two narrow ribs located laterally with respect to a central bore and perpendicularly or radially with respect to the central axis of the articulation elements. Spring elements are provided in one of the articulation elements which act on pretensioned force-measuring elements and are tensioned with respect to one another. The spring elements deform elastically and symmetrically around the ribs under the influence of a sinusoidally alternating torque, so that the force-measuring elements are loaded and unloaded alternately and generate measurement signals proportional to the forces acting on them.
