Abstract
An actuator system having a stationary circular array of mechanical devices. The actuator system includes two stationary motors: one motor to rotate the actuator implement around the circular array of mechanical devices until the desired mechanical device is reached; and a second motor to rotate the actuator implement into engagement with an actuator pin of the mechanical device. A nozzle includes a three-sided or U-shaped stationary enclosure, together with a movable gate that completes the enclosure and forms an adjustable size nozzle outlet. As the gate closes after a dispense is complete, a controlled flow of residual liquid exits the nozzle outlet to avoid any additional displacement, thus preventing the undesirable effect of liquid being squeezed out of the nozzle outlet as the gate closes. Conversely, when the gate opens, this sniff back action operates in reverse, thereby filling the nozzle outlet and preventing air from filling the nozzle.
