Abstract: A sealing device for a rotary feedthrough for receiving a rotating machine element whose outer side can be applied to another machine element, includes at least two sealing elements disposed in tandem in the axial direction of the machine element. Inner sides of the sealing elements are configured for forming an active sealing connection with the rotating machine element. At least one of the sealing elements can be pressurized with an additional force acting in the radial direction so that the force of compression acting on the rotating machine element for the at least one of the sealing elements can be adjusted relative to the force of compression acting on the rotating machine element due to at least one other sealing element.

Abstract: To achieve uniform heating of metal components in all their regions, a method and device for heating metal components using electron irradiation in a vacuum chamber includes multilayer holding elements having an outer layer facing the electron radiation. The outer layer is resistant to heat and exhibits good heat-absorption properties. The holding elements also have an inner layer facing the respective metal component and exhibiting good heat-radiating properties. The holding elements are used to hold the metal components in the vacuum chamber during heating.

Abstract: A method for cooling metal components highly heated in a chamber includes effecting a uniform cooling of an entire metal component. The metal component has regions each with a given mass, some of the regions having a larger mass than others of the regions. Housings are provided around regions with the relatively larger masses. The regions are subjected to the inert cooling gas in a controlled manner to a differing extent based upon the mass size. The housings are individually subjected separately with the inert cooling gas. A treatment device for cooling metal components includes a reservoir for holding inert cooling gas and a chamber for receiving a metal component to be cooled. The chamber is connected to the reservoir and has a housing for each of the regions with the larger mass. Each of the housing has an inlet orifice separately connected to the reservoir.
