Virtually all stars were observed between 2010 and 2012. Thirty-four stars were resolved into individual components (31 double and 3 triple), of which 14 binary systems (BD+41 43, HD2887, HD30466, HD36540, HD36955, HD37479, HD61045, HD89069, HD144334, HD164258, HD349321, HD343872, HD184471, HD196691) and 2 triple systems (HD37140, HD338226) were for the first time resolved by the astrometric method. Description: The results of our measurements of 31 binary systems, resolved into components are presented in Table 1, where the stars are laid out in the ascending order by their Right Ascensions. The table columns contain the following data: the number of the star in the HD/BD catalog, its number in the HIPPARCOS catalog, its WDS designation (2000.0 coordinates), the epoch of observations, companion's position angle theta and its error sigma_theta, the separation between the components rho and the error of this value sigma_rho in milliarcseconds (mas), the brightness difference between the components Deltam and the error of this value sigma_Deltam, the spectral range used lambda.
