We present emission-line fluxes for NGC 2452, NGC 7026, M3-30, and Lo 4 from IUE low-dispersion spectra that have been processed by the New Spectral Image Processing System (NEWSIPS). For NGC 2452, a terminal wind velocity of -4200 ± 300 km s-1 was determined from the C IV λ1549 P Cygni profile, while that of NGC 7026 is -4600 ± 300 km s-1, and -4800 ± 400 km s-1 for M3-30. The spectrum of Lo 4 is a stellar continuum with some absorptions and a questionable C IV λ1549 feature.
