    Abstract: A hot melt dispensing system includes a hopper, a delivery line, a shaker, and an air supply line. The hopper stores hot melt pellets and the delivery line delivers the hot melt pellets from the hopper. The shaker agitates the hot melt pellets. The air supply line supplies air that flows through the shaker to produce vibration and additionally flows through the delivery line to create a vacuum that draws the hot melt pellets through the delivery line.

    Abstract: A fluid handling system suitable for injecting a pressurized fluid from a pump that is driven by a motor into an oilfield network includes a manifold fluidly connected to the pump and a controller. The manifold includes an inlet for receiving the fluid from the pump, a plurality of outlets downstream of and fluidly connected to the inlet, and a plurality of electric valves downstream of and fluidly connected, respectively, to the plurality of outlets, each of the plurality of electric valves being configured to selectively open and close to regulate a flow of the fluid from the plurality of outlets to a plurality of wells fluidly connected, respectively, to the plurality of electric valves. The controller is configured to receive a plurality of flow rate values of the plurality of wells, determine a plurality of duty cycles for the plurality of electric valves based on the plurality of flow rate values, and determine a schedule for the plurality of duty cycles so that only one of the plurality of electric valves is controlled open at a given time.
