Zusammenfassung:	1,271,962. Vacuum degassing apparatus. SPETSIALNOE KONSTRUKTORSKOE BJURO TYAZHELYKH TSVETNYKH METALLOV PRI GINTSVETMETE and BALKHASHKY ORDENA LENINA GORNO METALL-URGICHESKY KOMBINAT IMENI 50-LETIA OKTYABRSKOI REVOLJUTSII. July 29, 1969, No.37889/69. Heading C7D. A vacuum degassing apparatus comprises a hermetically sealed container arranged for connection to a vacuum source, a spiral channel 2, one end of which is higher than the other, a first pipe 3 extending downwardly from one end of the channel for drawing molten metal to be degassed upwardly into the channel, and a second pipe 4 extending downwardly from the other end of the channel for discharging degassed metal.
