We present the timing parameters of nine pulsars discovered in a survey ofintermediate Galactic latitudes at 1400 MHz with the Parkes radio telescope.Eight of these pulsars possess small pulse periods and period derivativesthought to be indicative of ``recycling''. Six of the pulsars are in circularbinary systems, including two with relatively massive white dwarf companions.We discuss the implications of these new systems for theories of binaryformation and evolution. One long-period pulsar (J1410-7404) has a moderatelyweak magnetic field and an exceedingly narrow average pulse profile, similar toother recycled pulsars.Comment: 9 pages, 4 figures.
