    摘要: Metals and/or metallic compounds are condensed from a vapor in a reaction vessel into a condenser, the condensate initially solidifying to block an outlet at the bottom of condenser; subsequent operation of heating stages from the top to the bottom of the condenser to melt the solidified condensate ensures that, as the outlet becomes unblocked, the whole melt flows into a mould.

    摘要: A heat treatment apparatus for vacuum and high pressure operation includes a container within a vessel separated by thermal insulation. The vessel has a door for access to the container. Both the container and thermal insulation have separate doors mounted on a common frame pivotally mounted inwardly of the vessel door. The container door can be opened and closed from otuside the vessel when the thermal insulation and vessel doors are closed. Normally the container door is kept open in case of failure of the closing mechanism or in the event of a power failure.

    摘要: An electrically heated vacuum furnace is provided with special lead-through devices for transmitting current to the heating elements. In order to recognize gas discharges which can occur between a lead-through and a tank wall, the insulation of the lead-through is surrounded by an auxiliary electrode. A thermocouple can also be used instead of an auxiliary electrode. A signal derived from the auxiliary electrode can be used to shut off the furnace power to avoid damage thereto.
