Abstract

1,067,324. Vacuum induction melting furnaces. O. JUNKER. June 19, 1964 [June 20, 1963], No. 25402/64. Heading F4B. [Also in Division F2] The description and the drawings disclose substantially the same subject matter as that of Specification 1,067,326 but the claims specifically relate to the construction of the gas-tight sealing means for the gas-impermeable sleeve.
