Publication number: 20080315443Abstract: The invention relates to an adjustment method, especially for the adjustment of optical or fibre optical components, whereby a partial region of an actuator is locally heated in such a defined manner that compressive stresses are created therein as a result of the restricted thermal expansion of said heated partial region, caused by at least one other partial region of the actuator. If the yielding point ? of the material of the partial region is exceeded, said compressive stresses lead to the plastic compression of the heated partial region. Furthermore, said heated partial region is contracted during cooling and leads to a defined modification of the geometry of the actuator following the cooling process. Tensile stresses are created as a result of a restriction of said contraction by means of at least one other partial region in the previously heated partial region, and compressive stresses are frozen in the at least one other region.Type: ApplicationFiled: April 12, 2002Publication date: December 25, 2008Inventors: Burkhard Muller, Robert Burns Israelsen

Publication number: 20080292999Abstract: In a known method for heating an industrial furnace by pulsating combustion, gaseous or liquid reactants, comprising an oxidizing agent and fuel, are fed to a burner (3), with the volumetric flow of at least one of the reactants which emerges from the burner mouth (7) being changed over the course of time. On this basis, to provide a method which allows a simple and flexible change to the flow during pulsating combustion, according to the invention it is proposed that the change in the volumetric flow of the reactant over the course of time is generated by electrical actuation imparting deflections to at least one membrane (14) in a membrane space (13) which is connected upstream of the burner mouth (3) and is accessible to the reactant, which deflections cause changes to the volume of the membrane space.Type: ApplicationFiled: January 6, 2006Publication date: November 27, 2008Inventors: Horst Koder, Burkhard Muller

Publication number: 20070020214Abstract: The invention relates to a method for the permanent deformation of keratin fibers. According to said method, the fibers are treated with an aqueous preparation of a keratin-reducing substance prior to and/or after a mechanical deformation, then after a certain exposure time, the fibers are rinsed again with a first rinsing agent, fixed with an aqueous preparation of an oxidant, rinsed again after an exposure time and optionally treated again. Said method is particularly effective and kind to the fibers. The mixing and separation behavior is improved if at least one of the two aqueous preparations or the first rinsing agent is in the form of a multiple phase system containing at least one oil component and at least one N-acyl glutamic acid or the salts thereof. The multiple phase system is converted into a homogeneous system for a given time period by a mechanical movement for application to the fibers and separates again during the re-formation of the multiple phase system.Type: ApplicationFiled: June 19, 2006Publication date: January 25, 2007Inventors: Burkhard Muller, Thorsten Knappe, Birgit Rautenberg-Groth

Patent number: 5214596Abstract: System for determining the airspeed of helicopters, having a coupled measuring device to which is supplied by the cyclic and collective control signals, the attitude angles and the rotational velocities about the axes of the helicopter. The measuring device contains two models, namely a first model of the input behaviour of the helicopter motion, on which the cyclic and collective control signals act as input, and a second model of the system behaviour of the helicopter, on which the condition parameters act as input parameters. The estimated state parameters are obtained in an integration stage by integration of the algebraic sum of the outputs of the two models and the output signal of the correction arrangement, from which the values of the the velocity components are supplied to an indication. The integration stage is connected in front of a correction arrangement for the measured parameters of the rotational velocity and the attitude angle.Type: GrantFiled: February 20, 1992Date of Patent: May 25, 1993Assignee: Duetsche Forchungs- und Versuchsanstalt fur Luft- und Raumfahrt e.V.Inventor: H.
