Abstract: An active gas based on CO2 penetrates under pressure into a discharge chamber (20) via injection orifices (10) formed through the upstream face of said chamber. These orifices leave considerable solid portions (22) about themselves in said face such that the gas forms jets which diverge up to an outlet grid (12) constituting a common anode. Cathodes (8) are individually powered by a block (14) and give rise to discharges which are widened on the edges of said jets by large-amplitude gas recirculation currents, thereby increasing the electrical power injected. The invention is particularly applicable to power lasers.

Title: Log-polar signal processing

Filed: 1989-09-18
Granted: 1993-03-30
Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to a method and an arrangement intended for radio communication systems and effective in digi-talizing and subsequently processing numerically arbitrary radio signals.  The signals are represented by composite (complex) vec-tors which have been subjected to disturbances in the system, such that information in the signals has been lost.  This infor-mation is restored in its entirety when practising the present invention.  For the purpose of solving this problem, the inven-tive digitalizing arrangement includes a multistage logarithmic amplifier chain in which each stage is connected to a separate detector, the output signals of which are added in an adder.  The adder output signals are then transmitted to a first A/D-con-verter for digitalizing and converting the amplitude components of the signal.  At the same time, the undetected signal from the staturated output stage in the amplifier chain is transmitted to a second A/D-converter for digitalizing and converting the phase components of the signal.  The digital values obtained on the outputs of the AD-converters are applied to different inputs of a digital signal processor for numerical processing of the pairwise received digital values in a manner such as to restore the com-plete vector characteristic of the signal.
