Abstract: A prosthetic knee (10) for a transfemoral amputee has a monocentric rotational joint (20) that rotatably attaches an upper housing (12) attachable to the amputee's residual limb to a lower housing (16) attachable to a below-the knee prosthesis. A locking mechanism (32) disposed in the lower housing (16) has a piston (34) biased in a locked position releasably engaging the upper housing (12) preventing rotation of the rotational joint (20). An unlocking mechanism (32) having a trigger (48) attached to a posterior side of the lower housing (16) by a pair of spaced-apart trigger links (52) is configured to unlock the locking mechanism (32). A piston rod (62) having a first piston-rod end (64) pivotably attached to one of the trigger links (52) has a second piston-rod end (68) pivotably attached to the piston (34).

Abstract: A multi-purpose firearm servicing tool has an elongated tool body having a first end portion and a second end portion. A gas tube clamp is provided at a position between the first and second end portions of the elongated tool body. Opposing tube clamp surfaces of the gas tube clamp are selectively movable between a tube clamping configuration and a tube receiving configuration. A torque handle body has a tool body receiving cavity accessible through an opening at an end face at a first end portion thereof. The first and second tool body structures are stowable within the tool body receiving cavity. The torque handle body and the tool body each include respective means for allowing the tool body to be coupled to the torque handle body for allowing a rotational torque to be applied to the tool body through rotation of the torque handle body.

Abstract: A multi-purpose firearm servicing tool has an elongated tool body having a first end portion and a second end portion. A bit engaging socket is provided at the first end portion of the elongated tool body. A plurality of deposit scraping structures are positioned around a longitudinal centerline axis of the tool body at the second end portion thereof. A gas tube clamp is provided at a position between the first and second end portions of the elongated tool body. Opposing tube clamp surfaces of the gas tube clamp are selectively movable between a tube clamping configuration and a tube receiving configuration.
