Upsilon and Chi_b analyses at CLEO
  I detail recent work done by the CLEO collaboration using data gathered at the CESR accelerator concerning the Upsilon system. Results include B_S production at the Upsilon(5S), decays of the Upsilon(nS) (n=1,2,3) to tau pairs, the Upsilon di-electron width, decays of the Upsilon to two hadrons and a photon, and the observation of the first di-pion transition between chi_b states.
