Power switches are provided with measures for preventing a recommendation of the arc from the secondary current path to the main current path and/or measures for returning the current limiter during the recommutation of the light art. A corresponding arrangement for carrying out the method is provided with means in the power switch and/or current limiter for preventing a switch failure of the current limiter disposed in the secondary current path of the power switch. The current limiter can be especially a PTC current limiter.

Method for operating a switch with a connectable current limiter and corresponding arrangement

A method of operating a combustor (), to provide intimately mixed hot combusted gas () for a gas turbine (), includes feeding gaseous oxidant () and gaseous fuel () into the combustor () near a combustion flame () which has a tip end () and a root end (), where corona discharge occurs through adjustment of an electric field (), and where the corona discharge causes ionized particles () to form and also causes intimate turbulent mixing of the gases.

Electric flame control using corona discharge enhancement

A method and device are for influencing combustion processes, and include an electrical device. The electrical device engages with the flame front so that the electrical field thus produced, only penetrates areas of the flame front in which a stabilizing and harmful-substance-reducing effect is produced. The electrodes of the burner are arranged outside the region of the flame in the associated device.

In a gas discharge display device with a gas discharge space which is separated by a hole matrix from an electron acceleration space, helium, to which an amount of 0.1 to 10% of at least one of the gases argon, crypton, xenon, nitrogen or carbon dioxide is admixed, is used as the filling gas with an overall pressure of 0.5 to 5 mbar to obtain an enhanced contrast effect on the picture screen.

Gas discharge display device

In a pictorial display device containing a matrix of gas discharge cells in which discharge path is divided into an auxiliary discharge space for operation with low voltage, followed by a second space with short path length and high field intensity for accelerating the electrons, the cathode is subdivided into subcathodes with each of which a group of auxiliary anodes is associated to obtain a narrow, approximately wedge-shaped gas discharge which is fired and passed on line by line.
