Abstract: A lathe machine includes a tailstock unit having a bottom seat driven by a saddle of a turret unit to move longitudinally relative to a headstock by means of a first coupler unit, and a tailstock mount mounted on the bottom seat and driven by a turret mount to move transversely by means of a second coupler unit such that a selected one of a centering mandrel and a drilling tool holder disposed on the tailstock mount is in line with a spindle axis of the headstock. A positioning unit includes blocking and abutment members respectively disposed on the bottom seat and the tailstock mount and having rightward- and leftward-facing inclined surfaces which matingly abut against each other to permit the centering mandrel to be kept in line with the spindle axis, thereby rendering the centering process easy and precise.

Abstract: A removable guidewire funnel tool aids in backloading a catheter onto a guidewire. The guidewire funnel tool includes a pliable loading coupler having a lumen therethrough. The lumen has a tapered distal section that serves to receive a guidewire and a tapered proximal section that receives and couples with a correspondingly tapered distal tip of the catheter. The guidewire funnel tool has a longitudinal slot or area of weakness along the entire length of the loading coupler and a grip tab to enable easy removal of the guidewire funnel tool after the guidewire lumen of the catheter is loading with the guidewire.

Abstract: A wind turbine includes a rotor having one or more rotor blades, a pitch system for controlling the pitch angle of the one or more rotor blades, the pitch system having at least one pitch actuator, a pitch controller for generating pitch actuator control signals and sensor elements for establishing values of pitch performance parameters, and a compensation controller to compensate for disparities between the pitch actuator control signals and the values of pitch performance parameters, according to a control algorithm. The compensation controller is arranged to adjust parameters of the control algorithm of the compensation controller in dependency of the disparities.

Abstract: A method of assembling a rotor shaft assembly is provided. The method includes assembling a self-aligning bearing seat from a first assembly and a second assembly such that the self-aligning bearing seat substantially circumscribes a rotor shaft. The method also includes creating an interface defined between the first assembly and the second assembly, such that when the rotor shaft experiences misalignment the interface accommodates misalignment of the rotor shaft.

Abstract: The invention relates to a process for forming a part including a bore with a bearing integrally cast thereto, the thus formed part and apparatus for thus forming the part. The process includes hot machining a bore into a billet in a non-oxidizing atmosphere and introducing molten bearing material, e.g., molten bronze about a mandrel positioned in the bore while maintaining the billet, the mandrel and the bearing material in the non-oxidizing atmosphere. The mandrel is drawn from the bore while the bearing material is cooled by cooling and solidifying means therein adjacent an end of the mandrel which is last to exit the bore. The cooling is sufficient to progressively solidify the material as the mandrel is drawn through it and out of the bore.

Abstract: An automatic lathe wherein the carriage for an indexible tool turret is biased against a stop and can be moved toward the work spindle by a rotary cam which is driven by a hydraulic motor and is arrested by a hydraulic brake when the carriage reaches a selected position. The motor is automatically decelerated to crawling speed prior to complete stoppage of the cam and the brake is applied subsequent to deceleration of the motor and simultaneously with opening of an arresting valve which connects the supply and return conduits for the motor. The supply conduit continues to receive some pressurized fluid while the motor is at a standstill. Abrupt acceleration of the motor is prevented by maintaining the arresting valve in open position after a motor valve increases the rate of fluid flow from a pump to the supply conduit and by closing the arresting valve simultaneously with disengagement of the brake.
