Abstract: A reaction arm accessory for a power tool may include a body having a distal end configured to engage a fixed structure and an attachment end defining a splined connection configured to engage a splined interface of the power tool, the splined interface including a plurality of spline teeth defining gaps between adjacent spline teeth. The accessory may include a quick-change removal assembly supported in the body adjacent the splined connection and configured to selectively secure the reaction arm accessory to the splined interface of the tool. The quick-change removal assembly may include a collar rotatable between a locked position and an unlocked position, the collar including a plurality of locking protrusions and a spring surrounding the collar and configured to urge the collar towards the locked position.

Abstract: An offset drive accessory for a power tool includes a housing, and an input gear supported within the housing. The input gear is configured to rotate about a first axis. The offset drive accessory further includes an output gear supported within the housing. The output gear is configured to rotate about a second axis offset from the first axis. The output gear is couplable to a removable insert that is engageable with a fastener to transmit torque from the output gear to the fastener. The offset drive accessory further includes an idler gear supported within the housing. The idler gear is meshed with the input gear and the output gear such that the idler gear is configured to transmit torque from the input gear to the output gear. The offset drive accessory also includes a reaction arm removably coupled to the housing.

Abstract: Metering structure includes a rigid strut configured to support an optical element. A rigid shield mounted on the strut has a shield length which is substantially coextensive with the elongated length of the rigid strut such that rigid shield substantially encloses the strut along the entire shield length. The rigid shield has a surface finish which is highly absorptive of electromagnetic radiation in the optical spectrum. One or more thermal insulating material layers comprise a multi-layer insulation (MLI) system disposed between the rigid strut and the rigid shield. Rigid and flexure brackets secure the rigid shield to the strut.

Abstract: A power tool includes an output assembly defining a drive axis. A first socket rotatable by the output assembly in a first rotational direction. A second socket receives the first socket and is rotatable by the output assembly in a second rotational direction. A collar is coupled to the output assembly and is movable along the drive axis to releasably engage with the second socket.

Abstract: A power tool includes an ejection mechanism configured to eject an end of a fastener. The ejection mechanism includes an ejection rod that is actuated by a motor of a power tool to move from a first position to a second position to eject the end of the fastener. Following ejection of the end of the fastener, the ejection rod is returned to the first position by a return spring.

Abstract: A power tool, such as a tension control (TC) and/or shear wrench is provided. The power tool includes a powertrain having a motor and an output assembly the motor defines a motor axis of rotation and the output assembly defines a drive axis of rotation, which is oriented parallel to and offset from, or perpendicular to the drive axis of rotation. The motor and the output assembly are operatively coupled by a linkage assembly, which is configured to transfer rotational power from the motor to the output assembly. The output assembly includes a transmission configured to rotate both an inner socket and an outer socket of the output assembly.
