  • Patent number: 7383943
    Abstract: A method of repairing a slat conveyor includes an anchor bar and a ratchet puller. The anchor bar preferably includes an anchor frame and a pair of C-clamps. A first C-clamp is pivotally coupled to a first end of the anchor bar with at least one link and the second C-clamp is coupled to a second end of the anchor bar with at least one link. The anchor bar is secured to conveyor frame with the pair of C-clamps. A first end of the ratchet puller is secured to the anchor bar and to a first end of a broken conveyor chain. A second end of the ratchet puller is attached to a second end of the broken conveyor chain. The ratchet puller is actuated, until the first and second ends of the broken chain meet.

  • Patent number: 4856734
    Abstract: A reaction jet control system for a flying vehicle, the system comprising pairs (3, 4 and 5, 6) of jet reaction nozzles with associated gas flow supply ducts, the duct between two nozzles (3, 4) of any one pair including a first gas diverter valve (11B) and the duct between the pairs of nozzles including a second gas diverter valve (11A). This arrangement ensures accurate balancing of the gas flows between the nozzles and gives economy in use of the fuel supply.

  • Patent number: 4445180
    Abstract: An electric power plant, including a fossil fired boiler and a steam turbine, is operated by a control system including a plant unit master. The control system includes a boiler control for determining the inputs of fuel, air and water, and a turbine control for determining the position of the throttle valves introducing steam from the boiler to the turbine. The plant unit master provides a load demand reference in parallel to the boiler control and to the turbine control, whereby the turbine and the boiler are operated in a coordinated manner. Measuring means provide indications of throttle pressure, power generated by the system and turbine rotor speed. Distinct controllers, each including a controller and responsive to one of the aforementioned indications and its corresponding reference, modify the load demand reference before it is applied to the turbine control or to the boiler control.

  • Patent number: 4429528
    Abstract: An emergency fuel control system for an aircraft engine, which emergency fuel control system comprises means for supplying emergency fuel to the engine such that the fuel supplied to the engine is proportional to engine speed and pressure, first fluidic means which is controlled by a pilot's throttle lever giving a throttle demand and which includes fluidic sensor inputs for limiting engine performance, second fluidic means which has an acceleration control for generating a signal pressure as a particular function of engine compressor ratio, a fluidic mixer for mixing an acceleration control signal and a pilot's control signal such that the pilot cannot demand more fuel than it is safe for the engine to accept, and a fluidic output device which receives signals from the fluidic mixer and which generates a signal which has substantially the same shape as the acceleration control signal but which is at a lower level and which is used to define the minimum amount of fuel that is safely required by the engine in

  • Patent number: 4057715
    Abstract: An electric power plant including a steam generator and a steam turbine is operated by a control system including two redundant digital computers. Switching circuitry is provided for coupling one of the computers through interface equipment to the steam generator and the turbine and a generator according to programmed computer control. A data link is established between the computers to transfer manual/automatic status and other needed data from the control computer to the standby computer. A system is provided for detecting when certain hardware and software malfunctions have occurred and for responsively transferring control to the standby computer. The standby computer is tracked to the control computer so that control computer transfer can be made reliably without disturbing the electric power generation process. The turbine control includes a speed control loop which is implemented with computer operations.

  • Patent number: 3939328
    Abstract: An electric power plant including a steam generator and a steam turbine is operated by a control system including a turbine control, a boiler control and a plant unit master; each of the aforementioned controls includes integrating or adaptive controllers responsive to error signals to effect a desired control and ramp generators to provide an output against which a control process may be tracked. The integrating controllers include an integrating circuit for integrating an input error signal and a proportional circuit responsive to the error signal for providing an output signal to be summed with the output of the integrating circuit. The constant of the proportional circuit and the time constant of the integrating circuit are changed as a function of an index. In a control for an electric power plant, the index is the load reference provided by the plant unit master. A ramp generator is suggested that is capable of generating linear ramps at a fixed rate toward a known value, e.g.
