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.

Devices and methods can be used to apply an adhesion promoter, for example, ozone, over the surface of the biological tissues, before and/or concurrently with the application of the cosmetics to improve the durability and/or appearance of the cosmetics on the biological tissues. The devices can include a recirculation system and/or a filter system to reduce the likelihood of the chemical being released into the atmosphere and/or to increase oxidation of the chemical generated by the device after use of the device.

An ozone generator for a hot tub, the ozone generator comprising an elongate body comprising an inlet and an outlet to define a flow path therealong and first and second electrodes spaced apart to define a gap therebetween, said gap being provided along the flow path. The ozone generator is configured to apply an electrical charge to the first and second electrodes, in use, to generate an electric arc discharge across the gap. The ozone generator further comprises a shielding arrangement configured to isolate the first and second electrodes from the electric arc discharge generated during use. By isolating the electrodes from the electric arc discharge, they are shielded from surface oxidation and subsequent corrosion caused by the electric arc discharge, thereby improving service life.

An apparatus 10 for poling piezoelectric material includes a platen 22 which holds a sample 20 of piezoelectric material to be poled and a stage 30 to which the platen is mounted. The stage 30 is arranged to selectively move the platen 22 and thereby the sample 20 which the platen 22 holds. The platen 22 is movable by the stage 30 selectively between a first position and a second position. A corona source 40 generates a corona to which the sample 20 is exposed when the platen 22 is moved to the first position by the stage 30. An electrostatic voltmeter 60 having a probe 62 measures a surface potential of the sample 20 when the platen 22 is moved to the second position by the stage 30.
