  • Welding system
    Patent number: 10369668
    Abstract: A welding system is disclosed that includes a power supply, a controller in communication with the power supply, and a welder in communication with the controller. The controller detects a configuration of the welder that includes at least a 1G configuration. Upon the controller detecting the 1G configuration, the controller inverts a height adjustment and automatically calculates a contact tip to work distance.

  • Gas turbine engine fuel system with fuel metering valve
    Patent number: 7526911
    Abstract: A gas turbine engine fuel metering valve is configured to move within an operating position range having a first end position for establishing a first fuel flow rate, a second end position for establishing a second fuel flow rate, and an intermediate position located between the first and second end positions for establishing a third fuel flow rate. The first and second fuel flow rates are either both higher than or both lower than the third fuel flow rate.

  • Clearance control apparatus
    Publication number: 20080063509
    Abstract: A clearance control apparatus for controlling the clearance between a rotary assembly (17) and a casing (24) surrounding the rotary assembly (17) is disclosed. The clearance control apparatus comprises a temperature measuring device (34) to measure the temperature of a radially outer portion of the rotary assembly and a cooling arrangement (28) to cool the casing (24). A control system (36) is associated with the temperature measuring device (34) and the cooling arrangement (28) to control the extent of cooling of the casing (24). The extent of cooling is dependent upon the temperature of the aforesaid portion.
