Abstract: A specific electrode arrangement for a burner already exists with which the flame of the burner is influenced by using electrical fields, whereby these electrical fields pass through only areas of the flame in which a stabilizing and pollutant-reducing action occurs. According to at least one embodiment of the invention, the electrodes used to this end simultaneously serve both as probes for detecting flame properties as well as active field electrodes for influencing the flame properties. The probe signals can react to the voltage applied in an inertia-free manner to the electrodes without the involvement of mechanical elements. According to the associated device equipped with a burner and associated electrodes and with a power supply unit, the power supply unit furnishes a voltage that varies over time, and at least one measuring transducer exists that detects the current generated in the flame by the voltage between both electrodes and provides feedback to the power supply unit after amplification.

Abstract: For a low-pressure gas discharge switch, at least two main electrodes are arranged at least a distance d from each other, the electrodes in an arcing chamber forming a cathode and an anode of a discharge path for the low-pressure gas discharge. The gas discharge is triggered by increasing the electron density in a cathode cavity, at least the cathode in its disk-shaped area having at least one aperture, the cathode and anode apertures preferably being opposite and aligned with each other, for triggering the discharge. An arrangement generating a magnetic field superimposed on the discharge between the main electrodes (1, 1a, 2, 2a) are assigned to the main electrodes (1, 1a, 2, 2a), with which either a predominantly parallel magnetic field is generated or a predominantly perpendicular one, with regard to the direction of current in the discharge.

Abstract: Powder aerosols are introduced into a gas stream in metered form and without any aggregates. To this end, according to the invention, a powder is drawn, for example by mechanical device, from a reservoir area and is converted into a powder aerosol which is introduced within a flowing gas stream into a container to which ultrasound is applied. The ultrasound breaks down powder lumps and aggregates, and the aerosol can be fed in a uniform, fine powder distribution within the gas stream to a plasma burner. Apparatus for carrying out this invention includes a feed tube (4) connected to a mechanical powder feed device (6), so that an aerosol containing the powder enters a vessel (10) containing the ultrasound horn (2). The method and the associated apparatus are used for the coating of components, preferably for applying a protective coating to a turbine blade.

Abstract: Torque measurement is required in motors, in particular. It is already known to generate response signals in an axially offset manner at least at two points on a torque shaft by irradiating light onto the rotating torque shaft. An azimuthal offset of those signals produced by the torque over and above a rotary movement must be determined for evaluation purposes. An apparatus according to the invention for torque measurement on rotating torque shafts uses a continuous light beam to generate signals. A torsion-induced deflection of the light beam is geometrically amplified before an evaluation and an azimuthal offset is determined accurately therefrom as a time signal. The apparatus includes a device for generating optical response signals from at least two axially offset reflector systems at the torque shaft of the machine, which have individual concave mirrors in each case.
