ABSTRACT:
An arrangement for mounting lead-through conductors is disclosed. A ceramic plate is sealed between two steel flanges. The conductors pass through the ceramic plate and are sealed on both sides. When one side of the plate is exposed to high pressure, low temperature gas, and the other side of the plate is exposed to high vacuum at a higher temperature, the plate is protected from excessive stresses by providing gaskets on one side of the ceramic plate having a different coefficient of thermal expansion than the gaskets on the other side of the ceramic plate.
