Abstract: Controlling flow of gas in a gas pipeline network, wherein flow of gas within each of the pipeline segments is associated with a direction (positive or negative). Processors calculate minimum and maximum production rates (bounds) at the gas production plant to satisfy an energy consumption constraint over a period of time. The production rate bounds are used to calculate minimum and maximum signed flow rates (bounds) for each pipeline segment. A nonlinear pressure drop relationship is linearized to create a linear pressure drop model for each pipeline segment. A network flow solution is calculated, using the linear pressure drop model, comprising flow rates for each pipeline segment to satisfy demand constraints and pressures for each of a plurality of network nodes over the period of time to satisfy pressure constraints. The network flow solution is associated with control element setpoints used to control one or more control elements.

Abstract: A bulk material baler for binding bales of bulk material with more than two baling wires or straps. The baling wires or straps are bound around the bale with wire drive wheels that push the wire through a guide track around the bale and back to a knotter that ties together the ends of the bale wire. The narrow head of the present invention orients the drive wheels in a plane perpendicular to the plane of the bale wire loop, and makes it possible to put the wire feed drive wheels, knotter and guide track ends all in a 9¼ inches wide space so that adjacent baling wires can be bound around a bale simultaneously.

Abstract: A control system for a bulk material baler embodied in a machine readable data structure and including an instruction to a moveable guide track to move from a removed position to a closed position to create a guide track loop around a volume of bulk material to be baled while that bulk material is under compression and also including in instruction to a bale strap feed drive to feed a pre-determined length of strapping around the guide track loop, and including an instruction to a cutter to cut the end of the bale strap and including an instruction to a strap fastener to fasten together the ends of the bale strap and including an instruction to remove the moveable guide track section from around the bale and an instruction to release compression and an instruction to eject a bound bale.

Abstract: A tilt out head for a bulk material baler that includes a bracket for holding a baling wire feed drive, including an electro servo motor and drive wheels, a baling wire knotter including tying cylinders and an electro servo motor and optionally other equipment such as a cutter, a gripper, and tensioning pins. The tilt out bracket of the present invention pivots at its lower extremity so that the equipment on the bracket may rotate outwards and down away from a baler carriage to a stopped position that exposes all of the parts for ease of repair and maintenance.

Abstract: An operator interface for a control system for a bulk material baler includes interface means such as a touch screen or keyboard for an operator to enter process parameters into a control system memory. A display shows process parameter fields into which an operator may enter desired control parameters. The display also displays data feedback from baler process sensors. The baler control system then controls baling parameters as the operator directs including: strap feed position, strap feed speed, strap feed torque, strap release tension, tying cylinder position, tying cylinder speed and tying cylinder torque. The operator may also control carriage movement, alarm limits, shut off limits and monitor on the display baler processing data both currently and historically. Other aspects of automated baling may be optionally monitored or controlled through the operator interface of the present invention.
