  • Method and apparatus for degassing metallic melts
    Patent number: 3982913
    Abstract: An arrangement for the degassing of metallic melts in which a rotating member is immersed in the melt. The rotating member has step-shaped elements which form vacuum chambers or spaces during rotation of the member. The vacuum spaces are not filled with melt, and gases are extracted from the melt and carried away from the vacuum spaces with the application of inert gases or reaction gases.

  • Method and means for drawing samples from melts
    Patent number: 3967505
    Abstract: An arrangement in which samples drawn from a melt are sealed against air, and are allowed to solidify, while the gases given off are collected for analysis. A hollow, thin-walled, metallic element is used, which narrows at its lower end into an orifice. The element is degassed at high temperature before being sealed for use, to remove hydrogen and organic impurities.
