A device for generating ozone from oxygen-containing gas by silent electric discharge. At least two high-voltage electrodes and at least one ground electrode are nested. A discharge gap is defined between each high-voltage electrode and adjacent ground electrode. A dielectric is arranged in each discharge gap. In one embodiment, at least two discharge gaps are traversed by the gas, and a different voltage is applied to each gap according to the individual gap width. In another embodiment, filler material is arranged in an interstice between the high-voltage electrode and the corresponding dielectric, and the same amount of power is applied to each discharge gap.

Disclosed is a cascade insert for an ionising bar for the contactless neutralising of electrostatic charges and/or for contactless charging, in particular of insulation materials. The cascade insert includes a housing having at least one cascade circuit which has at least one transformer and a one- or multiple-stage cascade unit, said circuit units being potted with a potting material, and the output of the cascade circuit is coupled capacitively, inductively or resistively with a plurality of electrode points which are accommodated in a carrier extending in the direction of extension of the housing.

A discharge device is housed in a housing portion of a holder. The discharge device includes a housed section and a discharge electrode protruding from the housed section. The housed section is housed in the housing portion. The housed section includes a bottom wall and two side walls. The two side walls oppose each other in a longitudinal direction of the bottom wall. At least one of the two side walls is connected to the bottom wall via a curved surface. The curved surface guides a corner of the housing portion when the housed section is housed in the housing portion. As a result, the housed section is housed in the housing portion without catching on the corner.

A discharge device includes a connector portion, an electrode portion, and a housing portion. A voltage is applied to the connector portion externally. The electrode portion discharges by boosting and supplying a voltage from the connector portion. The housing portion houses the connector portion and the electrode portion. The housing portion includes a step portion between the connector portion and the electrode portion. The step portion is, for example, a recess.

A device for receiving and harvesting energy from the earth and its atmosphere for providing a supply of electrical energy.

An air conditioning apparatus according to an aspect of the present invention includes a main body including a suction part through which air is suctioned and a discharge part through which the air suctioned through the suction part is discharged, a fan disposed in the main body to allow the air to flow, an electric charge device coupled to the main body outside the main body to charge dust in the air, and a filter device disposed between the suction part and the discharge part in the main body to collect the charged dust particles.

A discharge electrode E in an electrode chamber C comprises a plurality of electrode members 8, 9. The electrode members 8, 9 are disposed facing each other by having a supporting member 4 therebetween, a gap is formed between the facing portions of the electrode members 8, 9, and by having the gap as a gas passageway 15, the gas passageway is opened in the leading end of the discharge electrode. A replacement gas having been supplied from a manifold pipe 3 is supplied to the gas passageway 15 via an orifice.

An expansion mount, electrode arrangement and a surface treater station include a mounting block with one or more clamps pivotally coupled to the mounting block to move between a connect position and a release position. When the mounting block is coupled to a surface treater, the one or more clamps are configured to engage the electrode in the connect position and disengage from the electrode in the release position.
