摘要:
The present invention relates to a method and device for uniformly heating products, the products (8, 15) being heated by a high-frequency electromagnetic alternating field. The method and the device are characterised in that the high-frequency electromagnetic alternating field for heating the products (8, 15) is produced by means of a semiconductor generator (4). By using a semiconductor generator (4), temperature fluctuations in the event of fluctuating load due to the transport of the products (8, 15) through the heating volume (7, 17) are reduced, so that a more uniform temperature of the products (8, 15) can be achieved in the heating process.

A glass-to-metal bushing for ignitors of airbags or belt tensioning pulleys. A metal pin is arranged in a slot in the base plate in the fixing material, the base plate being formed by one element whereby the base geometry describing the slot is produced by at least one separation process. Structure is provided between the front and rear of the base plate for preventing relative motion of the fixing material in the direction of the base plate rear portion across from the inner circumference of the slot.
