Abstract: Cylindrical carbon blanks are assembled into one or more upright stacks which are advanced stepwise in an upward direction in one or more upright tubes which insulate the column or columns from the surrounding atmosphere. The blanks in the upright tube or tubes are preheated by exchanging heat with an inert gas, such as pure argon, and the preheated blanks are thereupon conveyed along one or more horizontal path sections into the upper end of an additional tube wherein the blanks are heated to graphitizing temperature by a series of electrode pairs. The thus obtained graphite electrodes are cooled by inert gas which is thereupon admitted into the upright tube or tubes to preheat fresh carbon blanks.

Abstract: Cold carbon-containing blanks which are impregnated with a carbon-containing material are introduced into a cold autoclave which is thereupon sealed and filled with inert gas prior to heating of the interior of the autoclave to tempering temperature. The tempered products are cooled in and thereupon removed from the autoclave, and the inert gas is relieved of hydrocarbons and other harmful substances which are released by the impregnating material during tempering.

Abstract: There is provided a method and apparatus for impregnating carbon articles with hot impregnating medium in a closed autoclave whereby the articles to be impregnated are introduced into the autoclave which is then closed and heated by means of a heat exchanger to the impregnating temperature at which point the impregnating medium is introduced to fill the autoclave and then pressurized to impregnate the articles. Subsequent to impregnation, the impregnating medium is removed from the autoclave and the closed or sealed autoclave and the impregnated articles are cooled to a temperature below a predetermined "lower limit temperature" and the articles are then removed from the autoclave. The "lower limit temperature" is chosen to eliminate the emission of harmful off-gases.
