Abstract: An apparatus for coating a PET container in a coating chamber includes a lance that introduces material and energy into the container while it is in the coating chamber. This results in a reaction that coats the bottle's interior with a silicon oxide. Before reaching the coating chamber, the bottle will have passed through a cooling system connected to coating chamber. The cooling system passes cooled gas through a feed, thereby cooling said bottle before it reaches the coating chamber.

Abstract: The present invention relates to a device for coating containers with a barrier layer having at least one plasma chamber, which encloses at least one treatment space, in which at least one container with a container interior can be inserted and can be positioned on the treatment space, wherein a gas lance is provided which can be introduced into the container interior and which further acts as microwave antenna, with the plasma chamber being designed to be capable at least of partial evacuation and being designed to fill the container interior at least partially with a plasma and a process gas. The device is designed such that the container can be preheated by means of a plasma, more particularly by means of a microwave plasma, using a noble gas which can be introduced into the container interior through the gas lance.

Abstract: In a method for the diagnostics of an internal combustion engine exhaust gas system that includes a particle filter, first and second sets of value vectors are determined, each including associated values for absolute pressure upstream and downstream of the particle filter, a differential pressure determined from the values of the absolute pressure, an exhaust gas volume flow through the particle filter, and a temperature of the exhaust gas volume flow. After a temperature-standardization of the pressure values, characteristics for dependence of the pressure values are generated from temperature-standardized values of the first set of value vectors and possibly stored as reference characteristics. By comparing temperature-standardized values for the absolute pressure on the inlet and outlet sides of the particle filter and the differential pressure of the second set of value vectors with reference characteristics, flow anomalies can be determined in the exhaust gas system.
