Abstract: A powder-spraying appliance for electrostatic powder coating of work pieces. In order to achieve particularly good charging of powder particles, the powder-spraying appliance contains a chamber, into which a powder/air mixture is introduced transversely to a spraying direction via a supply conduit. An earth electrode and a plurality of high-voltage electrodes are disposed in the chamber. All of the electrodes are flushed with cleaning air in order to avoid powder deposits on the electrodes.

Abstract: The method has the fluidisation occurring in a twin chambered device (2), the first chamber (3 )receiving the compressed air that then passes through a "frit" to the second chamber(4). The powder in the second chamber leaves the device from the nozzle (11) and is charged up. The powder is filled through the hole (9) which can be closed off. Apart from the nozzle and the air inlet and outlet valves (17,19), the fluidisation takes place in a closed chamber, the valves being used to maintain the correct pressure proportions. Additional mechanical energy is passed to the fluidised bed of the second chamber in the form of vibration.

Abstract: The power line has an additional, compensation, loop (1) surrounding at least one phase conductor. Into this compensation loop a compensation current is fed via a driving voltage. This current's phase angle and amplitude are adjusted relative to the phase conductor current angles and amplitudes so that its magnetic field works in opposition to that of the phase conductors. The driving voltage in the compensation loop and in at least one additional loop, which also surrounds a phase conductor and is connected with the original loop, is generated so that the overhead line is divided into at least two main sections. One section is with the original loop and one is with the additional loop.
