Patent DE-2452113-A1 (DE)
Title: Pigment concentration in mixed paint measurement method - uses colour sample and reflection factor curves or colour comparison
Inventor: BEHNKE CHRISTIAN DIPL PHYS
IPC: G01J3/46
Filed: 1974-11-02
Abstract: Reflection factors of the sample are measured at different wavelengths, and standard curves for reflection factors of different pigments are provided for different wavelengths as a function of their concentration. When the reflection coefficients or modified absorption coefficients are calculated for a pigment concentration combination, interaction between pigments is taken into consideration. The modified absorption values for the different wavelengths are calculated from the concentrations. The procedure is continued until the concentrations between two repetitions do not change. The method is applicable for similar colour materials used in combination as well as for high concentration values.

Title: High accuracy and stability synchronisable oscillator - has frequency compared with reference value obtained by mixing highly stable frequency with interpolation frequency
Inventor: RAUCHENECKER KONRAD DIPL ING
IPC: H03L7/183
Filed: 1976-09-27
Abstract: The oscillator is inserted into a control circuit containing a frequency divider which can be set to an arithmetical series of division ratios, and a phase discriminator. The discriminator derives a control voltage from the phase difference between the oscillator divided frequency voltage and a reference voltage of the same frequency. This control voltage readjusts the oscillator frequency to a nominal value depending on the reference voltage frequency and the division ratio. The reference voltage (UR) is obtained by mixing a reference a.c. voltage (Uo) of a highly accurate and stable frequency (fo) with an interpolation voltage (Ui) variable over a much narrower frequency range (delta fi) whose width corresponds to the difference (delta fa) between two adjacent oscillator frequencies determined by the division ratios. The interpolation frequency (Ui) passes before mixing through a second frequency divider (13) which is adjustable synchronously with the first (4) to the same division ratios.
