Abstract: A needle assembly is provided having a needle cannula, a hub, and a pair of opposed radially outwardly extending paddles. The needle cannula has a proximal end and a distal end with a puncture tip. The hub has a proximal end and a distal end. The hub supports the needle cannula at a distal end. A twist fitting connector is provided at the proximal end. The pair of opposed radially outwardly extending paddles each have a digit pad configured on the hub in an anatomically preferential position when the needle is affixed to a syringe with the connector. In use, a user palm-grasps a barrel of the syringe so as to point the puncture tip away from a user when receiving at least one digit on at least one of the digit pads during mating and demating from the syringe. A method is also provided.

Abstract: The diagnostic system for diagnosing a rotor imbalance of a wind turbine based on acceleration data measured on a nacelle of a wind turbine which is supported by a tower includes a measuring device provided with a triaxial vibration sensor suitable for measuring acceleration data corresponding to vibrations occurring on the nacelle. The system also includes a processing system for processing the acceleration data, suitable for determining the rotor imbalance according to the acceleration data measured on at least two axes on the nacelle. The invention also relates to a method for diagnosing the rotor imbalance of a wind turbine.

Abstract: To facilitate the removal of a bearing housed in an arm of a turbomachine casing, which bearing guides a transmission shaft of the turbomachine, a casing arm includes a body with a vertical portion and a base defining a portion of a shaft housing; an additional part removably attached to the body and defining a bearing housing opening in the shaft housing; and a removable shim inserted between the base and the additional part. A turbomachine including such a casing arm is also described, as well as a method for removing the bearing from such a turbomachine, including removing the shim and moving the additional part towards the base, thereby allowing access to the bearing.

Abstract: Servovalve with jet-type pilot stage including an ejector for ejecting a jet of fluid that is movable relative to a deflector adapted to generate a pressure differential that can be used to move a power distribution member of the servovalve, the ejector projecting radially from a column extending along a longitudinal axis and to which the ejector is fastened, being in fluid communication with a central passage of the column via which the ejector is fed with fluid, the column having a first end pivotably engaged in a part of the servovalve in the vicinity of a pressure feed thereof and via which the fluid is introduced into the central passage of the column, the column having a second end loaded by a torque motor to apply selectively to the column a rotation torque about the longitudinal axis in either direction relative to a rest position.

Abstract: An intermediate casing comprising an inner annular hub, an outer annular barrel and an annular part for separating flows situated between the hub and the outer barrel. A primary stream is delimited between the hub and the separation part. A secondary stream is delimited between the separation part and the outer barrel. At least one hollow arm extends radially from the hub to the outer barrel, passing through the primary and secondary streams. A transmission shaft extends radially in the hollow arm. The hollow arm comprises a hydraulic-fluid outlet situated downstream of the transmission shaft. The arm further comprises a bypass channel or pocket able to bypass the transmission shaft.
