Abstract: In a cylindrical elongated furnace for treating material at high temperature in a gaseous atmosphere under high pressure, the furnace chamber is insulated from the walls of the pressure chamber by at least three tubular parts arranged one inside the other with insulating parts. At least one ring is provided attached to one of the tubular parts and having a downwardly and inwardly sloping similar part secured to the inside of this part and directed towards, but terminating short of, the opposed part.

Abstract: A cylindrical elongated furnace for treating material at high temperature in a gaseous atmosphere under high pressure is formed of a high pressure cylinder with end closures projecting into it and a furnace chamber arranged in the high pressure cylinder. The furnace chamber is insulated from the walls of the pressure chamber by a cylindrical casing having gas-impermeable tubes arranged one inside the other with an insulation between them. At least one layer of insulating material in the casing engages only the outer or inner surface of one tube and is spaced from the adjoining tube, the space between being filled with gas. The insulating material may be held against the outside of one of the tubes by rings or a spiral strip running helically.

Abstract: A vertical furnace for isostatic hot-pressing of powder bodies includes a cylindrical pressure chamber formed of a high pressure cylinder and end closures projecting into the cylinder. Insulation arranged in the chamber includes a cylindrical insulating wall and end insulation members. There is a seal between the upper end closure and the high pressure cylinder. In order to protect this seal against heat from the inside of the chamber, a heat resistant seal of a semi-porous material such as asbestos is arranged below the first seal in the space between the pressure cylinder and the upper end closure projecting into the cylinder.
