  We present three preliminary results from SLD on B decays: an inclusive
search for the process b-> s gluon, a measurement of the branching ratio for
the process B -> D D-bar X, and measurements of the charged and neutral B
lifetimes. All three measurements make use of the excellent vertexing
efficiency and resolution of the CCD Vertex Detector and the first two make use
of the excellent particle identification capability of the Cherenkov Ring
Imaging Detector. The b->sg analysis searches for an enhancement of high
momentum charged kaons produced in B decays. Within the context of a simple,
Jetset-inspired model of b->sg, a limit of BR(b->sg) < 7.6% is obtained. The B
-> D D-bar X analysis reconstructs two secondary vertices and uses identified
charged kaons to determine which of these came from charm decays. The result of
the analysis is BR(B -> D D-bar X) = (16.2 +/- 1.9 +/- 4.2)%. The results of
lifetime analysis are: \tau_{B^+} = 1.686 +/-0.025 +/- 0.042 ps, \tau_{B^0} =
1.589 +/- 0.026 +/- 0.055 ps and $\tau_{B^+}/\tau_{B^0} = 1.061 +/-
^{0.031}_{0.029} +/- 0.027.
