摘要： A compressor blade root heating system for a turbine engine is disclosed. The compressor blade root heating system may be formed from one or more induction heaters formed from one or more induction coils positioned in close proximity to a root of a compressor blade. In one embodiment, the induction heater may be coupled to a static casing component positioned immediately upstream of a first row of compressor blades on a rotor assembly such that the induction heater is stationary during turbine engine operation. The induction heater causes eddy current formation, which heats the row one compressor blades. This heating increases the fracture toughness of the material forming the rotor and compressor blades, thereby increasing the mechanical life cycle.

摘要： A non-axisymmetric electromagnet coil used in plasma processing in which at least one electromagnet coil is not symmetric with the central axis of the plasma processing chamber with which it is used but is symmetric with an axis offset from the central axis. When placed radially outside of an RF coil, it may reduce the azimuthal asymmetry in the plasma produced by the RF coil. Axisymmetric magnet arrays may include additional axisymmetric electromagnet coils. One axisymmetric coil is advantageously placed radially inside of the non-axisymmetric coil to carry opposed currents. The multiple electromagnet coils may be embedded in a molded encapsulant having a central bore about a central axis providing the axisymmetry of the coils.

摘要： A magnetron actuator for moving a magnetron in a nearly arbitrary radial and azimuthal path in the back of a target in a plasma sputter reactor. The magnetron includes two coaxial rotary shafts extending along the chamber central axis and coupled to two independently controllable rotary actuators. An epicyclic gear mechanism or a frog-leg structure mechanically couple the shafts to the magnetron to control its radial and azimuthal position. A vertical actuator moves the shafts vertically in tandem to vary the magnetron's separation from the target's back surface and compensate for erosion of the front surface. The rotary actuators may be separately coupled to the shafts or a rotatable ring gear may be coupled to the shafts through respectively fixed and orbiting idler gears. Two radially spaced sensors detect reflectors attached to the inner and outer arms of the epicyclic gear mechanism for homing of the controller.

摘要： A continuously variable multi-position magnetron that is rotated about a central axis in back of a sputtering target at a freely selected radius. The position is dynamically controlled from the outside, for example, through a hydraulic actuator connected between a pivoting arm supporting the magnetron and an arm fixed to the shaft, by two coaxial shafts independent controllable from the outside and supporting the magnetron through a frog-leg mechanism, or a cable connected between the pivoting arms and moved by an external slider. The magnetron can be rotated at two, three, or more discrete radii or be moved in a continuous spiral pattern.

摘要： A burner for combusting hydrocarbon fluids which may contain additional components as additives or contaminants and in the form of a gas, liquid or particulate matter, e.g. waste oil wherein the oil is atomized in a nozzle disposed in a housing defining a combustion chamber for receiving an oxidizing fluid, e.g. oxygen, so that atomized oil is mixed with the oxidizing fluid for combustion. Control of the length to diameter (L/D) ratio of the combustion chamber results in lower operating noise levels for the burner during combustion.
