A survey of visual binaries with the CORAVEL spectrometer permitted detection or confirmation of unknown spectroscopic subsystems, sometimes with small amplitude radial velocity variations. A computer program was developed to analyze the blended dips of such systems, giving correct determinations of the individual radial velocities for separations down to 3 km/sec. Four visual binaries for which a spectroscopic subsystem was discovered (HD 7331, HD 214608) or confirmed (HD 196795, HD 219018) are discussed. Orbital elements of the last three show small ratios of visual to spectroscopic period and small amplitude of radial velocity variation. Individual masses are derived and included in satisfactory models combining photometry, spectral types, parallaxes, and rotation.
