Publication number: 20120291316Abstract: Couplers for attaching an accessory to an excavator arm of an excavator. Couplers having a first side for attaching the coupler to the excavator arm and a second side onto which the accessory will be coupled. The coupler includes a latch for selectively securing and releasing an attachment pin of the accessory in a jaw, groove, hook or slot in the second side of the coupler. The coupler is fully controllable from within the cab of the excavator and it allows improved security in the securement of the accessory to the coupler, i.e. preventing accidental decouplings, but while still allowing intentional decoupling operations to be carried out without undue burden.Type: ApplicationFiled: August 1, 2012Publication date: November 22, 2012Applicant: Miller UK LimitedInventors: Gary Miller, Ronald Keith Miller, Gary Pendleton, Howard Reay, Paul Grant

Publication number: 20120132518Abstract: When a magnetron is scanned about the back of a target in a selected complex path having radial components, the erosion profile has a form depending upon the selection of paths. A radial erosion rate profile for a given magnetron is measured. Periodically during scanning, an erosion profile is calculated from the measured erosion rate profile, the time the magnetron spends at different radii, and the target power. The calculated erosion profile may be used to indicate when erosion has become excessive at any location prompting target replacement or to adjust the height of the magnetron above the target for repeated scans. In another aspect of the invention, the magnetron height is dynamically adjusted during a scan to compensate for erosion. The compensation may be based on the calculated erosion profile or on feedback control of the present value of the target voltage for a constant-power target supply.Type: ApplicationFiled: February 7, 2012Publication date: May 31, 2012Applicant: Applied Materials, Inc.Inventors: Keith A. Miller, Daniel C. Lubben

Publication number: 20120034081Abstract: 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.Type: ApplicationFiled: August 9, 2010Publication date: February 9, 2012Inventors: Christopher W.

Publication number: 20110297538Abstract: 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.Type: ApplicationFiled: August 19, 2011Publication date: December 8, 2011Applicant: APPLIED MATERIAL;S, INC.Inventors: Keith A.
