  • Method and device for inhibiting contamination of a workpiece
    Patent number: 7410547
    Abstract: A method and device for inhibiting contamination of a workpiece during the heating of a workpiece by a contaminant. The method includes placing the workpiece in a first container, and, in a first step, filling the first container with a protective gas. The first container is placed in a second container, and in a second step, the second container, and hence the first container contained therein, is evacuated to create a vacuum inside the first and second containers so that during the first and second steps the partial pressure is reduced for the contaminants in the first container before the workpiece is heated.
    Type: Grant

  • Method of tying two or more components together
    Patent number: 7341176
    Abstract: Method of tying two or more components together using a fastener. Each component is provided with a hole and the components are placed so that the holes overlap one another in order to receive the fastener in the holes. The fastener is placed in the holes and mechanically pressure-loaded and heated in order to deform the fastener to tie the components together. The fastener is heated essentially only during the fastener deformation phase in order to minimize the heat transfer from the fastener to the components being tied.
