  • Process for tire manufacture with on-line determining of carbon black concentration and distribution in rubber compounds and other carbon black containing materials
    Patent number: 5702550
    Abstract: To determine the carbon black distribution two measurements of spectral intensities of separately produced plasmas are carried out with different time delays relative to a particular laser pulse, the time delay for the second measurement for determining the spectral line intensities of a reference element carbon (I.sub.C') and at least one analysis element (I.sub.A.n') being smaller than for the first measurement; for determining the spectral line intensities of the reference element (I.sub.C) and the other analysis elements (I.sub.A.n).Evaluation of the measurements is performed by reference to calibration information based on reference measurements, which information shows the magnitude of the concentration ratio of the other analysis elements or the at least one analysis element to the reference element (c.sub.A.n /c.sub.C or c.sub.A.n /c.sub.R) as a function of the appurtenant intensity ratio values.
    Type: Grant
    Filed: March 21, 1996
    Date of Patent: December 30, 1997
    Assignee: Pirelli Coordinamento Pneumatici S.p.A.
    Inventors: Christoph Carlhoff, Martin Jogwich, Claus-Jurgen Lorenzen, Marco Nahmias
  • Process for determining carbon black concentration and distribution in rubber compounds and other carbon black containing materials and device to carry out the process
    Patent number: 5537207
    Abstract: To determine the carbon black distribution two measurements of spectral intensities of separately produced plasmas are carried out with different time delays relative to a particular laser pulse, the time delay for the second measurement for determining the spectral line intensities of a reference element carbon (I.sub.C,) and at least one analysis element (I.sub.A.n,) being smaller than for the first measurement; for determining the spectral line intensities of the reference element (I.sub.C) and the other analysis elements (I.sub.A.n).Evaluation of the measurements is performed by reference to calibration information based on reference measurements, which information shows the magnitude of the concentration ratio of the other analysis elements or the at least one analysis element to the reference element (c.sub.A.n /c.sub.C or c.sub.A.n /c.sub.R) as a function of the appurtenant intensity ratio values.
