    Abstract: The present invention relates to a heater, primarily for pressure furnaces for extremely high temperatures for isostatic compression. The resistance elements of the heater are arranged between two metal rings at different levels which are supported by conductors. The resistance elements comprise two groups of wires arranged in a righthand and a lefthand spiral, respectively. The wires are joined together at the intersection points by means of lashing.

    Abstract: A method of containing radioactive or other dangerous material separately or intermixed with a bonding compound of a material, resistant to leaching by water, in a gas-tight container and of converting the material by hot isostatic pressing (HIP) into a dense body. The material is filled into a cylindrical container having a corrugated bellows-like wall. The dangerous material is prevented from filling up the annular spaces formed by the corrugations, by means of a barrier means placed inside the container. A metallic netting combined with a paper-like sheet of ceramic material makes a suitable barrier means.
