All are double-lined binaries and all except the last one are contact binaries. The orbital data must be considered preliminary because of the relatively small number of observations (6 - 12), a circumstance which is partly compensated by the good definition of the broadening functions used for the RV determinations.accepted by AJ for Januray 2007; order of the authors changed re V.1Astrophysicstext
