Abstract: A system for making a tire tread includes an extruder, a roller die having a first axis of rotation, and a conveyor that receives a round strip (or noodle) of green rubber from the extruder and feeds the strip of green rubber to the roller die. The system further includes a drum having a second axis of rotation, wherein the roller die is configured to apply the strip of green rubber to the drum. The system also includes a controller, wherein the controller is configured to control a translation of the roller die in a first direction parallel to the first axis of rotation. The controller is configured to control a roller die rotation speed and a drum rotation speed, and the controller varies at least one of the roller die rotation speed and the drum rotation speed during translation of the roller die.

Abstract: An apparatus and a method are provided for discharging a plurality of fluids downhole. In one aspect, the apparatus may include a first chamber and a second chamber separated by movable barrier, wherein draining the fluid from the first chamber causes the barrier to move and allow an actuating member to drain the second fluid from the second chamber.
