The invention relates to a method and an apparatus for the treatment of substrates, in particular for the coating of plastic containers on a rotary installation. A plurality of treatment devices are arranged on the rotor and pass through a plurality of process phases as a function of their angle position on the rotor. For at least one process phase, the angle position can be set variably as a function of the current rotational speed of the rotor.

The invention relates to a fluid rotary leadthrough having a journal and a sleeve. The sleeve and the journal are sealed off with respect to one another. The journal and the sleeve each have a line connection. The line connections, at least from time to time, are connected to one another via a fluid passage so that a flow of fluid through the fluid rotary leadthrough is made possible. The journal is arranged rotatably in the sleeve.

摘要:
A coating apparatus is provided for simplifying the introduction and removal of workpieces into and from a reactor for plasma coating and to increase the throughput. The coating apparatus has a reactor with a moveable sleeve part and a base element, at least one sealed coating chamber being defined between sleeve part and base element when the latter two parts are fitted onto one another. The coating apparatus also has a device for introducing electromagnetic energy into the at least one coating chamber. The reactor has at least two coating places.

An objective lens comprises a housing, an iris diaphragm and a plurality of lens groups. For focusing the objective lens while minimizing the variation of the image angle at least two lens groups are adapted to be moved relative to the housing. The one lens group is arranged in front of the iris diaphragm. The other lens group is arranged at least partially behind the iris diaphragm.
