Query: Spectroscopic orbits of subsystems in multiple stars. V   Spectroscopic orbits are determined for inner subsystems in nine stellar
hierachies (HIP 2863, 4974, 8353, 28796, 35261, 92929, 115272, 115552, and
117596). Their periods range from 2.5 to 312 days. For each system, estimates
of masses, orbital inclination and other parameters are given.
