  • Removable stud for joining casing flanges
    Patent number: 6641326
    Abstract: A stud for interconnecting adjacent flanges of a flanged joint in a tubular casing. The flanges each contain apertures to receive the stud and each flange is inclined relative to the casing outer surface, with one flange extending radially outwardly and the other flange extending radially inwardly, as a result of which one end of the stud extends externally of the flanged joint and the other end extends internally. The stud includes an external formation that is of non-circular form and that is carried by the stud between the threaded ends to extend radially outwardly. The external formation is adapted to be engaged by an anti-rotation member to prevent unintended rotation of the stud. The stud is removable from the flanged joint without the need to completely disassemble the joint to remove a broken stud.

  • Flow-through chemical actinometer for ultraviolet disinfection reactors
    Patent number: 6596542
    Abstract: A chemical actinometer for determining the absolute level of exposure to ultraviolet light of a fluid to be treated for disinfection purposes. The actinometer includes a translucent sample cell through which the chemical actinometric fluid flows. The area of exposure of the actinometric fluid is controlled by allowing the ultraviolet light to pass through only a portion of the sample cell. A suitable actinometric fluid is a combination of iodide and iodate in a solution. The sample cell is positioned within an ultraviolet disinfection reactor at a position to receive ultraviolet light from the ultraviolet light source.

  • Gas turbine engine fuel control method
    Patent number: 6584762
    Abstract: A fuel control system for an aircraft gas turbine engine that includes a thrust augmentation system. An augmentor fuel pump is arranged to provide pressurized fuel to an exhaust nozzle throat area actuation system to eliminate the need for a separate hydraulic pump to provide pressurized fluid for exhaust nozzle actuation. An augmentor fuel bypass arrangement is provided to enable the augmentor fuel pump to provide pressurized fuel to the main fuel pressurizing valve and to components operated by the main fuel system in the event of failure of the main fuel pump. The augmentor fuel pump pressure and output flow are controlled as a function of thrust augmentation demand and main fuel system operation. The system provides redundancy by enabling either the main fuel system or the augmentor fuel system to maintain engine operation if one of the fuel systems fails or provides inadequate fuel flow.

  • Vehicle parking control system
    Patent number: 6577248
    Abstract: A parking control system in which a mobile telephone is used to commence and to terminate parking of a vehicle within a parking zone. A parking system user sends a user-specific code to a parking system computer at the commencement of and at the termination of a parking period. A vehicle-specific code corresponding with the parked vehicle is stored in the computer upon commencement of a parking period. A portable parking control unit can read the vehicle-specific code from a parked vehicle and can establish communication with the parking system computer, which is informed of the parking zone concerned. When the control unit requests information concerning vehicles parked within a particular parking zone, the computer sends corresponding information relating to one or more additional parking zones that are geographically close to the parking zone in question.
