Scientific paper

The results of observations performed during 1984-1985 of three stars belonging, most likely, to binary systems consisting of the Wolf Rayet star and the compact satellite are presented. The variability of the HD 193 077 spectrum is episodic in nature. HD 191 765 demonstrates the high level of spectral activity. Correlations are found between the variations of the emission lines during a time of about 1 hr.
