Abstract: A fastener which can compensate for misalignment and tolerance build-up while assuring no looseness or rattle of the connection, for connecting structure, such as seats, partitions and cabinets to a track installed in an aircraft. The fastener includes a rotatable stud for locking the fastener down to the track, serrated engagement means for allowing substantial adjustment between the track and the connected structure, means to eliminate looseness between the track and the structure and means to maintain and indicate a locked condition of the fastener.

Abstract: A coat hanger rack silently elevated above passenger seats to store coats overhead and to provide more passenger room. The elevating mechanism consists of a powered, threaded rod on which a threaded nut traverses as the rod rotates, moving the coat rack vertically. The nut moves the hanger yoke. Lateral forces are kept from the screw by transmitting them from the yoke to slipper bearing against guides. The Teflon slippers movable along the guide preclude looseness, high bearing pressure and roller noise.
