Abstract: A rotating latch assembly includes a lift housing extending between a first opened end and a second opened end and defining a chamber extending therebetween. A support tube is slidably disposed in the chamber and extends between a first end and a second end. The lift housing is movable along the support tube between an extended position and a lowered position in response to a movement provided by an actuator wherein the extended position is the lift housing being adjacent to the first end and the lowered position is the lowered position being adjacent to the second end. A retaining member is disposed between the lift housing and the support tube and attached to the support tube and the lift housing for maintaining the lift housing in the extended position as the lift housing moving from the lowered position to the extended position.

Abstract: A latching assembly includes a lift housing extending along a center axis between a first and a second opened ends and defining a chamber extending therebetween. A support tube is disposed in the chamber and extends between a first and a second end. A moving member is disposed between the support tube and the lift housing for moving the lift housing between an extended position and a lowered position. The moving member includes an inner ring and an outer ring. The inner ring extends about the support tube. The outer ring is attached to the lift housing for translating an axial movement of the support tube into a rotational movement. A plurality of engagement members located between the inner ring and the outer ring for moving the inner ring and said outer ring axially along the center axis from the extended position to the lowered position.

Abstract: Systems and methods are disclosed for controlling the pitch angle of a propeller and rotor assembly that selectively limit the pitch angle according to a selected mode of operation. The system comprises a fine stop collar defining a primary channel, an oil transfer bearing (OTB) extending across the fine stop collar, and an actuator piston engaged with a propeller blade crankshaft to vary propeller blade pitch, wherein the annular piston is positioned about the OTB in fluid communication with the primary channel.

Abstract: A sliding door closing device having an easy door opening function with an opening system. The closing device provides a slider with an attachment and gripper on one side of the device, and a properly shaped support of a moving roller on the other side of the device. A pusher contacts a roller support of the roller with a slider gripper and an opening spring and choke. The opening system allows for the opening of a door by pushing the door on vertical strip or on the edge.
