Query: Recycled Pulsars Discovered at High Radio Frequency   We present the timing parameters of nine pulsars discovered in a survey of
intermediate Galactic latitudes at 1400 MHz with the Parkes radio telescope.
Eight of these pulsars possess small pulse periods and period derivatives
thought to be indicative of ``recycling''. Six of the pulsars are in circular
binary systems, including two with relatively massive white dwarf companions.
We discuss the implications of these new systems for theories of binary
formation and evolution. One long-period pulsar (J1410-7404) has a moderately
weak magnetic field and an exceedingly narrow average pulse profile, similar to
other recycled pulsars.
