Abstract: A seal assembly for a rotary machine, such as a turbine engine, may include a seal rotor comprising a rotor face, a seal slider comprising a slider face, a seal stator, wherein the seal slider is slidably coupled to the seal stator, and wherein the slider face and the rotor face define a primary seal. The seal slider may be configured to slidably engage and retract the slider face with respect to the rotor face. The seal assembly may further include a secondary seal disposed between the seal slider and the seal stator. The secondary seal may be configured to compress and rebound and/or to expand and rebound, over at least a portion of a range of motion of the seal slider.

Abstract: An instrument pick has a triangular planar body; a concave thumb platform; and an index finger slot. The body has rounded vertices, including a plucking vertex. The thumb platform has concentric grooves and a thumb cavity sidewall extending between the thumb platform and the body to form a drainage cavity. The thumb platform sidewall has an opening that connects to the drainage cavity. The finger slot has a base flanked by a pair of curved side walls. The side walls taper together to form a ridge that resist the user's index finger from sliding towards the plucking vertex. The finger slot has ventilation openings that connect to the drainage cavity to collect perspiration. The pick stays in place between thumb and finger even with a loose grip and can be customized for different playing styles.

Abstract: A turbine engine having a stator, a rotor, and a seal assembly. The rotor being rotatable about a rotational axis. The seal assembly having a carriage assembly, a seal body and a biasing element. The carriage assembly being carried by the stator. The carriage assembly defining a seal cavity. The seal body being provided within the seal cavity.

Abstract: A turbine engine comprising an engine core having at least a compressor section, a combustor section, and a turbine section in axial flow arrangement defining an axial direction and an engine centerline. The turbine engine further having a rotor and a stator, a carriage assembly carried by the stator, and a seal assembly biased toward the rotor.

Abstract: A snow mold includes a front snow mold portion and a back snow mold portion. The back mold portion is operable to be coupled to the front mold portion by inserting protrusions disposed on a flange of the back mold portion into receptacles disposed on a flange of the front mold portion. The front and back mold portions may be coupled by rotation of a rotatable fastener.

Abstract: An actuated shroud system configured to control tip clearances in a rotatable machine is provided. The system includes a rotor including a plurality of blades. Each of the plurality of blades includes a blade tip, and each blade tip includes a radially outer tip surface angled in the radial direction. The system also includes a shroud circumscribing the plurality of blades and including a radially inner surface angled complementarily to the radially outer tip surface of the blade tip. The radially inner surface and the radially outer tip surface define a tip clearance gap therebetween. The system further includes a shroud actuator operably coupled to the shroud, the shroud actuator configured to translate the shroud in at least one of an axial direction and the radial direction such that the tip clearance gap is variable based on a position of the shroud actuator.

Abstract: A bearing seal is provided with an annular outer casing having an axially extending portion and a radially inwardly extending portion. A sleeve member is disposed within the annular casing and includes an axially extending portion adapted to be attached to a rotating shaft and a radially outwardly extending portion. An annular seal including a seal body is mounted to the annular casing. A first seal lip extends axially from the seal body and engages the radially outwardly extending portion of the sleeve member. A dual contact lip extends from the seal body and includes a first seal portion and a second seal portion each contacting the sleeve member at axially spaced locations.
