A total number of 14 eclipsing binaries with A-F spectral type primary components were observed for 22 nights. We confirmed small-amplitude oscillating features of a recently detected pulsator TW Dra, which has a pulsating period of 0.053-day and a semi-amplitude of about 5-mmag in B-passband. We discovered new pulsating components in two eclipsing binaries of RX Hya and AB Per. The primary component of RX Hya is pulsating with a dominant period of 0.052-day and a semi-amplitude of about 7-mmag. AB Per has also a pulsating component with a period of 0.196-day and a semi-amplitude of about 10-mmag in B-passband. We suggest that these two new pulsators are members of the newly introduced group of mass-accreting pulsating stars in semi-detached Algol-type eclipsing binary systems. Description: We carried out CCD photometric observations for 22 nights from December 2001 to December 2002, using a SITe 2K CCD camera attached to the 61-cm telescope at the SOAO. We changed the passband from V to B on January 2002 because δ Scuti-type pulsators show the largest amplitudes in B-passband. File Summary:
