Title: Heat-insulated hot-drawing tool for branched container prodn. - of conical shape esp. for making T-junctions in switchgear casings
Inventor: DIETRICH JOHANNES
IPC: B21C37/29
Filed: 1973-04-06
Abstract: The surface of a tool for enlarging the side opening in tubes or containers for e.g. high-tension switchgear filled with an insulating-gas, has a heat-insulating gap or coating to reduce the heat conducted away from the metal being formed. When a T-junction is required in a tubular container, an elliptical hole is made and a conical drawing tool pulled through the hole to make a circular outlet collar. To reduce the heat lost through the tool, various insulating techniques are used. In a three-part tool consisting of a conical core on which a wire cage is mounted, followed by a conical cap which is in contact with the metal being drawn, the cage forms an air gap. Instead of the cage, the gap can be filled with an insulant or the surface of the core can be machined to form horizontal or vertical grooves, thus creating air gaps between core and cap. Alternatively a one-piece tool with an insulating, ceramic coating is used. A suitable scale-resisting steel is used for the outer cap.

Title: Starting system for fissionable gas generator - turns fuel and air into combustion gas by a catalyser
Inventor: GULDEN PETER
IPC: F02M27/02
