Abstract
Improved orbital elements for 22 binary systems are presented. For 12 syste ms, masses are calculated using available trigonometric parallaxes and maki ng certain assumptions regarding the mass ratio. For the other 10 systems, provisional elements are provided that should provide relatively accurate e phemerides for the next decade.
