  • Method for separating impurities from a chemical metallizing bath
    Patent number: 4162217
    Abstract: A bath solution is fed to a centrifuge wherein the impurities are precipitated onto the drum wall, due to centrifugal force and in the absence of electrical current, from which they are subsequently removed.

  • Process and apparatus for controlling metal thickness, and deposition and degradation rates
    Patent number: 4142099
    Abstract: Metal layer thicknesses on articles during formation or degradation, as in electroless or electrolytic deposition or chemical etching, are measured and controlled by a process comprising determining the radiation scattering capacity of a corresponding metallic layer deposited on or removed from a test sample while the test sample is present in a bath solution during formation or degradation of the metal layer. Also provided is a novel immersible sensor for measuring the rate and thickness of metal layers being deposited or degraded.

  • Arrangement for the fluid treatment, especially etching, of objects in assembly-line-like fashion
    Patent number: 3967632
    Abstract: The arrangement includes a treatment fluid supply chamber, a first treatment chamber located above the treatment fluid supply chamber, and at least one additional treatment chamber located above the first treatment chamber. Objects are conveyed along a first predetermined path leading through the first treatment chamber and also along a second predetermined path leading through the additional treatment chamber. Treatment fluid is pumped up from the common treatment fluid supply chamber to both of said treatment chambers, and the thusly pumped fluid is discharged onto objects in both treatment chambers.
