Abstract: The invention relates to a device and a method for plasma treatment of hollow bodies. The invention is in particular suited for the protective plasma treatment of the inner surface of thermally sensitive hollow bodies such as plastic bottles. The plasma treatment according to the invention can, for example, consist of chemical activation, sterilization, cleaning or coating. One or more hollow bodies are put into a processing chamber for treatment. The processing chamber is in fluid connection with at least one plasma source. An exhaust device on the processing chamber generates a negative pressure in the processing chamber relative to the plasma source so that plasma can expand out of the plasma source into the processing chamber and hollow body.

Abstract: The invention relates to a device and method for generating a barrier discharge in a gas flow, comprising a reactor chamber permeable by the gas from an inflow side to an outflow side, a first electrode, a dielectric that shields the reactor chamber against the first electrode, and a second electrode, wherein the second and the first electrode can be switched to connect to a voltage source. To briefly expose a greater portion, preferably all, of the gas flow through the reactor chamber to a plasma, at least two discharge elements associated with the first electrode and made of electrically conductive material protrude at least partially into the reactor chamber and are electrically insulated from each other and the first and second electrodes, and the second electrode is disposed relative to the discharge elements such that discharges occur between the discharge elements and the second electrode in the reactor chamber.

Abstract: For improving the variability in the coating of substrates a coating apparatus is proposed having a plasma generator for generating a plasma jet which exits from a coating head of the plasma generator. A first particle reservoir and a second particle reservoir are provided. The particles from the first particle reservoir and the second particle reservoir are supplied to the plasma jet as a particle mixture via a transport pipe. A supply control device is provided for setting the amount of particles from the first particle reservoir fed into the transport pipe relative to the amount of particles from the second particle reservoir.

Abstract: An apparatus for producing plasma, includes a container provided with at least one discharge electrode and a power supply unit that has at least one coupling electrode that can be capacitively coupled to the discharge electrode. The power supply unit is adapted to be removable from the container. The at least one coupling electrode is disposed beneath an insulating layer. In this way, the user can not come into direct contact with a coupling electrode after removing the power supply unit.

Abstract: A container (2) for powder (1), a method for marking of the containers (2) for the powder (1) and an apparatus (200) for use of a powder (1). At least one RFID Chip (20) provided in the container (2), wherein the RFID chip (20) stores at least one set of parameters for material characterization of the powder (1) in the container (2). A unique key (21) is assigned to every type of powder (1) by means of which the data in the RFID chip (20) located in the container (2) are readable, writeable and updateable via an antenna (10) arranged outside the container (2).

Abstract: A cleaning attachment, especially for a vacuum cleaner, includes a housing, a connection for a vacuum tube, an intake opening for ambient air, a plasma generator arranged in the housing to generate plasma, and at least one cleaning opening or a channel, along which a mixture of plasma and air passes over at the surface to be cleaned before the mixture is drawn back into the housing and through the connection. As a result, the cleaning attachment can also treat the air and the dirt with a sterilizing and odor-neutralizing action.
