|20100094471||CONTROL SYSTEM - A control system receives control information generated from reference information received from system sensors of physical parameters. The control system uses the information to control a plurality of control devices. The control system has a second control unit which receives and processes the control information and generates control device output, indicating which control device should be operated. A plurality of physical switches are provided, each of the switches represents one of the plurality of control devices. A first group of selected switches are closed and a second group of nonselected switches are open. A logic array receives the control device output and compares the control device output with the first group of selected switches or the second group of nonselected switches and generates appropriate valve operation outputs.||04-15-2010|
|20100089456||METHOD AND APPARATUS FOR LOW POWERED AND/OR HIGH PRESSURE FLOW CONTROL - The present invention relates to a fluid control system for regulating a fluid. A control device positionable between an inlet and outlet includes a first bellows, a second bellows, a resilient member, a diaphragm and a valve. The diaphragm and valve is each in fluid communication with the inlet and outlet, the valve movable between a closed position and an open position. An adjustment feature is associated with adjusting a force applied by at least one of the first bellows and the second bellows, adjustment of the adjustment feature not requiring disassembly of the control device. In response to a predetermined fluid force applied against the diaphragm by the regulated fluid flowing from the inlet toward the outlet, the first bellows, the second bellows and the resilient member apply a combination of opposed forces to selectably move the valve toward a position for regulating the regulated fluid.||04-15-2010|
