Abstract: A device for applying unipolar electrical charges to a moving, essentially electrically conductive insulating surface. An elongated corona electrode, e.g., including a number of tip electrodes, along with one or more auxiliary electrodes, and an electrically conductive counter electrode, are provided. The counter electrode supports the insulating surface, and a high-voltage d.c. source is connected to the electrodes. A carrier made of electrically insulating material is provided in the form of a channel, including a bottom wall and two side walls. The free edges of the side walls face the counter electrode. The corona electrode is arranged in the channel and at the bottom wall, and does not project over the free edges of the side walls. The auxiliary electrode(s) is arranged at, or in the vicinity of, each edge of the side walls, between the corona electrode and the counter electrode. One pole of the high-voltage d.c.

Abstract: A device for neutralizing electrostatic charges by way of corona discharge comprises discharge electrodes and earthed counterelectrodes, the discharge electrodes being capacitively connected to an alternating high-voltage source. A row of individual discharge electrodes is applied to one side of a carrier consisting of dielectric material galvanically separated from one another in the form of thin, electrically conductive layers. A continuous, electrically conductive coating is arranged on the other side of the carrier and opposite to the discharge electrodes, this coating being connected to the high-voltage source and providing a capacitive coupling of the discharge electrodes to the high voltage.

Abstract: A bar-shaped device for generating electrical charges by corona discharges comprises a high voltage cable surrounded by an insulating casing, extending parallel to the longitudinal axis of the device and adapted to be connected to a high voltage source, a plurality of needle electrodes connected to high voltage via the high voltage cable and arranged in at least one row along the longitudinal axis of the device, an insulating member accommodating the high voltage cable and the needle electrodes and an outer sheath surrounding the insulating member and having a longitudinal slot, wherein the needle electrodes penetrate the longitudinal slot and the edges of the longitudinal slot form counterelectrodes for the needle electrodes. The outer sheath consists of plastic and has grooves at the edges of its longitudinal slot parallel to the row of needle electrodes. A metal stranded wire provided with a casing made of pliable plastic is inserted into each of these grooves as counterelectrode.

Abstract: A plug connector for high-voltage coaxial cables. The cable comprises an inner conductor, an inner insulation, a metallic screen netting and an insulation, outer sheath. The plug connector comprises a plug-in contact element connected to the inner conductor, a metal sleeve connected to the screen netting and an insulating housing connecting the contact element to the metal sleeve. A sealing sleeve made of elastic, electrically insulating material is pushed onto the inner insulation of the cable. The contat element penetrates into the inner conductor such that the inner insulation arranges itself sealingly againsts the inner surface of the sealing sleeve. Owing to the connection of the insulating housing to the metal sleeve, the sealing sleeve undergoes such deformation that it arranges itself sealingly with its outer surface against the inner surface of the insulating housing.
