  • Multiple ball launch assemblies and methods of launching multiple balls into a wellbore
    Patent number: 7571773
    Abstract: Multiple ball launch assemblies comprise a plurality of ball launch pods disposed around an outer wall surface of a housing. The ball launch pods are operatively associated with a flow tube disposed within the housing. An actuator assembly rotates the flow tube to align a first opening in the flow tube with a first ball launch pod so that a first ball is launched into the wellbore. Further rotation of the flow tube aligns subsequent openings in the flow tube with subsequent corresponding ball launch pods so that subsequent balls are launched into the wellbore.
