Abstract:
A method of processing an article having a substrate and a cobalt-phosphorous coating disposed on the substrate includes heat treating (22) the article. At least one physical characteristic of the cobalt-phosphorous coating is altered (24) using the heat treating to thereby change (26) a performance characteristic of the article. For example, the article may be an actuator component having a bore or a shaft that is movably disposed at least partially within the bore.
Abstract:
A microwave position sensing system (12) includes a plurality of target components (14, 18, 22, 24) that each move between multiple positions. A microwave generator (28) produces a microwave frequency signal (34). A divider (36) receives the microwave frequency signal (34) and splits the microwave frequency signal into a plurality of position sensing signals (38a-38e). The position sensing signals (38a-38e) are respectively sent to the plurality of target components (14, 18, 22, 24) to determine a position of each of the target components. Each position sensing signal (38a-38e) may also be calibrated. In one example, first and second frequencies are transmitted through a common wave guide (50). The first frequency is reflected prior to reaching the target component to produce a calibration signal (54). The second signal, which is used to detect the position of the target component (14, 18, 22, 24), is calibrated using the first frequency.

PROBLEM TO BE SOLVED: To provide a wind turbine with articulated blades whose conversion efficiency is improved.SOLUTION: The wind turbine 10A includes: inboard blades 12A, 12B, 12C; outboard blades 14A, 14B, 14C; a hub 16; a winch 18; a drive device 20; cables 22A, 22B, 22C; pulleys 24A, 24B, 24C; elbows 26A, 26B, 26C; and spring loaded hinges 28A, 28B, 28C. The outboard blades pivotably connected to the inboard blades are driven with respect ot the inboard blades by cables so that swept angles Ψ, Ψ, Ψare varied. Thus, the conversion efficiency for wind turbine is optimized in view of wind conditions, etc. In low wind conditions, the outboard blades achieve maximum conversion efficiency by extending the swept angles to a position up to 180° between blades. In higher wind conditions, the outboard blades drive the inboard blades up to 180° or less of the swept angles. Consequently, the wind turbine 10A is not required to be shut down even in higher wind conditions.

A journal sleeve (34) is radially outboard the intermediate foil (18). The top foil (14) and the intermediate foil (18) establish apertures configured to make fluids communicate with each other between a first position radially inboard the top foil (14) and a second position radially outboard the intermediate foil (18).
Abstract:
PROBLEM TO BE SOLVED: To provide a starter for an auxiliary power source, which damps torque shock at clutch engagement and reduces the damage and breakage of a starter shaft.SOLUTION: A starter for an auxiliary power source includes a direct current motor operably connectable to an auxiliary power source. A clutch is arranged to the direct current motor in an electrically parallel relationship and configured to operably connect the motor to the auxiliary power source when engaged, the motor and the clutch powered by a common input line. A time delay switching element is located and configured to delay power delivery to the direct current motor thus providing for full engagement of the clutch prior to initiation of rotation of the motor.

PROBLEM TO BE SOLVED: To provide a barrier and a seal which efficiently separate a volatile environment and an electronic device so that an electric spark and oxygen do not interact.SOLUTION: A motor 100 includes a rotor 170 configured to be exposed to a volatile environment 105 and an electronic device 135 for rotating the rotor 170. A housing 110 includes a cylindrical portion 120 closed by an end portion 125, and the electronic device 135 is housed in the cylindrical portion 120. The electronic device 135 is separated from the volatile environment by a non-metallic barrier 175. In the housing 110, O-rings 145 held by four groups of radial-direction grooves 140 serve as a flexible seal so as to protect a ceramic material of the non-metallic barrier 175 from deflection in the motor 100 due to bending or twisting and from vibrations and impact that may break a barrier made of glass in a firm attachment structure.
