Abstract: In a high pressure press which has a seal holder, a high pressure seal is provided between the wall of a high pressure cylinder and a die or an axially movable plunger projecting into the cylinder, which is composed of two sealing rings, one of which has an outer surface abutting the cylindrical wall and an end surface abutting the seal holder, while the other ring has a cylindrical surface abutting the plunger and a surface abutting the seal holder. The portion of the outer surface of the first ring abutting the cylindrical wall which is nearest to the seal holder is provided with generally longitudinally extending draining channels therein.

Abstract: In the hydrostatic extrusion of compound billets, in which the billet is formed of a core of one material and a casing surrounding the core of another material, and in which a gap is left during the assembly of the billet to allow for deformation of the casing, the core is provided with a point and the casing has an inwardly directed conical flange within which the point of the core rests. At the back end, the core is provided with a sealing device for preventing the entry of fluid into the space between the core and the casing. In order to prevent the compression of the air in the space between the core and the casing, the core is provided at its front end with passages which open into the point of the core and which communicate with the space between the core and the casing, providing an air escape arrangement.

Abstract: In manufacturing blades for gas turbines with a plurality of inner cooling channels by isostatic compression, a sintering capsule of deformable material is provided with thin-walled tubes arranged substantially parallel to the capsule wall parts corresponding to the high and low pressure surfaces of the blade. A powdered material is poured into the capsule, which is then evacuated, sealed and heated to at least 800 DEG C. Thereafter the heated capsule is subjected to an external gas pressure of at least 500 bars. Simultaneously with the compression, the tubes are subjected to such a high internal gas pressure that the linear decrease in the tube cross-section is at most 50 percent.

Abstract: A vertical furnace for treating material at high temperature and under high pressure has a stand into which a cylindrical pressure chamber is introduced. This stand is formed of a high pressure cylinder with top and bottom end closures which project into the cylinder. A furnace chamber is formed within the pressure cylinder by two hat-shaped parts with insulating material between them. These parts rest on an annular portion of the bottom closure. The inner part of the bottom closure is removable for charging the furnace.
