    Abstract: Device for setting fire rings in gaskets which comprises means for supporting a metallic sheet provided with holes having upstanding cylindrical rims dimensioned and positioned to register with holes in the gasket, means for cutting rings encircling these rims, means for locating the gasket on the rings so that the rims project through the gasket holes, and means for pressing the rims are down against the gasket. The invention includes a machine which carries out all but the first of these steps successively and automatically.

    Abstract: The process of hot extruding metals and alloys which are subject to surface contamination at their deformation temperature is improved by coating the billet surface, while cold, with a thin layer of a powdered metal such as copper, and thereafter placing a second coating of a powdered amorphous material on top of the metal powder layer. The amorphous material is capable of forming a continuous protective layer when heated to the temperature at which surface contamination takes place during the extrusion operation.
