A system for connecting transaction services to an ATM that includes a network. The method comprises melt reacting an ester-substituted diaryl carbonate and a multifunctional compound of the formula:in the presence of catalyst to form an oligomer comprising less than 2,000 ppm of an ester-linked terminal group, and melt polymerizing the oligomer to form a polycarbonate. One end of the adjustment member is pivotally mounted to the front optical module, and the other end of the adjustment member is screwed on the rear optical module to form the optical projection module. To reduce breakage of the bobbin, each clip engages the bobbin perpendicular to the width of the ferrite core. The first blade has a fitting arrangement and the second blade having a spring arrangement.
