Hi guys. I need help with this circuit. I don't understand how does it work. Can anyone explain to me this circuit? Its the ultrasonic transmitter by the way, and IC 3 is 4093. VR4 is used to adjust the frequency to 40 khz.

The bottom section of the 4093 inverts the pulses from the pulse generator so that the transistors are driven by th opposite phases of the pulse, compared to the top transistors,,,push pull,
