We test the capabilities of 0.4 m telescopes equipped with an \'{e}chellespectrograph to derive fundamental parameters and elemental abundances of fourlate-B type stars: HR 342, HR 769, HR 1284, and HR 8705. The medium resolution(R~14000) spectra covering the wavelength range of 4380-7350 {\AA} of the fourstars have been obtained using the 40-cm-telescope in Ankara University KreikenObservatory (AUKR). Using spectrum synthesis, we were able to derive theabundances of eleven chemical elements. We find that these stars do not showremarkable departures from the solar abundances, except for HR 8705 and theprimary component of HR 1284, which exhibit slight underabundances of a fewelements, i.e., O, Mg, Al, Si, and Fe. We also find that HR 1284 is probably anew spectroscopic binary star. In order to model the spectrum of this object,one of us (TK) has developed a new graphic interface which allows us tosynthesize the composite spectrum of binary stars.
