This paper reports on the results of a study of S59 ultraviolet spectral scans of the spectroscopic binaries Beta Persei, Mu super 1 Scorpii and Gamma2 Velorum. In the case of Mu super 1 Sco it was found that the Mg II doublet at 2800 A undergoes intensity variations that may be indicative of variable emission in the photographic spectrum. The continuum in the 2490-2590 A range deviates from the continuum of the comparison stars. In Gamma2 Vel, flux variations in the 2770-2870 A region have been detected.
