  • Melting method for alloys
    Patent number: 10196711
    Abstract: A method for producing metal alloys. The method allows the production of metal alloys consisting of at least two metals having a high melting point difference. Here, the higher melting metal is melted first and the lower melting metal is melted with a delay by means of heat transfer whereupon the metals mix together. This enables to obtain metal alloys with high purity and low evaporation losses, which in particular allow the use of contaminated starting components such as recycled metal.
    Type: Grant
    Filed: November 25, 2015
    Date of Patent: February 5, 2019
    Assignee: ALD VACUUM TECHNOLOGIES GMBH

  • Process for disposing of perlite waste
    Patent number: 5813968
    Abstract: The present invention relates to a process for disposing of perlite, wherein perlite particles are removed by suction from a source, mixed with water and then compressed, whereby the volume of the perlite is reduced by the compression to about a third or a fifth of its original volume.
