  Pulsars with periods more than 0.4 seconds in the declination range -9o <
decj < 42o and in the right ascension range 0h < r.a.< 24h were searched in
parallel with the program of interplanetary scintillations monitoring of a
large number of sources with the radiotelescope LPA LPI. Four-year observations
carried out at the central frequency 110.25 MHz in the band 2.5 MHz and in six
frequency channels with the time resolution 100 ms were used for the search.
Initial detections of candidates for pulsars were based on the Fourier power
spectra averaged over the whole observations period. The candidates for pulsars
were checked in more details from observations analysis with higher
time-frequency resolution: 32 frequency channels with time resolution of 12.5
ms. 18 new pulsars was discovered, their main characteristics are presented.
