We confirm the presence of the secondary spectrum in two SB2 systems: HD
108642 and HD 434. Lines of both components in both systems are clearly
travelling and crossing. This enabled us to improve the previous mass
ratio estimate in the case of HD 108642 and to determine it for the fist
time in HD 434.
