  • Patent number: 12252263
    Abstract: A rod assembly includes a tubular rod body formed from a composite material and a localized sleeve installed to the rod body. The sleeve is secured to the rod body by application of heat to the sleeve material. A bushing is located radially between the rod body and the sleeve. The bushing is configured to absorb thermal energy of the application of heat. A door and hold open rod assembly of an aircraft includes a door, and a hold open rod assembly secured to the door. The hold open rod assembly is configured to support the door in an opened position when the hold open rod is deployed. The hold open rod assembly includes a tubular rod body formed from a composite material, and a localized sleeve installed to the rod body. A bushing is located radially between the rod body and the sleeve.

  • Publication number: 20250060773
    Abstract: A locking mechanism for a hold open rod. The hold open rod includes a first elongate member and a second elongate member, slidably arranged to move between a first configuration and a second configuration, the second configuration being extended relative to the first configuration. The mechanism includes a locking mechanism operable between a locked state and an unlocked state and arranged, in the locked state, to prevent the first and second elongate members from returning to the first configuration. The first elongate member includes a first surface. The locking mechanism includes a locking member moveable between a first position and a second position. The locking member includes a second surface.

  • Patent number: 12214892
    Abstract: A one-way speed limiter includes a first housing including an inner surface. defining a speed limiter receiving zone. A second housing includes a flange and a second wall including an inner surface portion that includes a stop feature. A ball housing including a ball member is rotatably supported in the speed limiter receiving zone. The ball member selectively engages the stop feature. A friction clutch is disposed between the ball housing and the first housing. The friction clutch selectively retards rotation of the ball housing. A motor shaft is selectively rotatably connected to the ball housing. The motor shaft including a first end supported at the ball housing and a second end. The motor shaft is rotatable relative to the ball housing in a first direction and selectively rotatably constrained relative to the ball housing in a second direction to selectively engage the friction clutch.

  • Publication number: 20250020156
    Abstract: A nut for use in an actuator assembly having a rotatable screw includes an outer nut portion and an inner nut portion removably coupled to the outer nut portion. The inner nut portion is rotatably couplable to the rotatable screw. At least one anti-rotation pin is positionable between the outer nut portion and the inner nut portion to restrict rotation of the inner nut portion relative to the outer nut portion.

  • Publication number: 20240409582
    Abstract: Embodiments of the invention are directed to inhibitors of MIEN1-mediated cancer signaling transduction pathways to inhibit cancer cell migration and their use as a cancer therapy. The inhibitors are a hexamer peptide and a heptamer peptide (therapeutic peptides) from the ITAM and the prenylation motif of MIEN1 that exhibit anti-cancer activity both in vitro and in vivo.

  • Publication number: 20240409227
    Abstract: A hold open rod has a control sleeve, an outer cylinder, lock balls, a lock sleeve, a piston, a piston head, a release spring, and a lock spring. The control sleeve has first and second cavity sections, an inner radial surface, a CS channel, and a pin. The outer cylinder has an OC inner cavity, OC inner and outer radial surfaces, an OC axial end wall, lock ball apertures, and a pin guide slot. The lock balls are configured to pass through the lock ball apertures. The piston has first and second sections. The piston head has an outer radial surface, a channel, and a piston bore. The piston bore is configured to receive the first section of the piston. The release spring biases the control sleeve toward a first axial end. The lock spring biases the lock sleeve toward a second axial end.
