Abstract: An automated sofa bed includes the usual elements and structure of a conventional sofa, an extensible articulated bed frame, and power means to extend and retract the frame. The basic sofa includes a rigid, stationary frame adapted to receive conventional seating pillows and formed with a cavity to receive the folded articulated bed frame. The bed frame comprises a plurality of generally rectangular sections pivotally connected to each other on traverse axes and foldable into a relatively compact package storable within the cavity in the rigid stationary frame, and extendable into a relatively horizontal arrangement suitable for use as a bed. At least one section of the bed frame is mounted on pivotal links to control its path of movement, and power means is applied through floating power links to the bed frame to move it between its extended and stored positions. The preferred form of power means includes cable means connected to the floating power links and an electric motor to drive the cable.

Abstract: A system for reliably limiting the maximum positions to which the power control lever of an aircraft engine may be set in the thrust reversal mode corresponding to whether the aircraft is in the air or on the ground. A plurality of cable drums, one for each of the power control lines extending between the cockpit and the engines of a multi-engine aircraft, is associated with an adjustable stop mechanism which provides a first stop position for the cable drum when the aircraft is in the air with landing gear up and a second stop position permitting increased reverse thrust when the aircraft is on the ground. The system is coordinated with the landing gear position sensing system of the aircraft and works in conjunction with presently installed thrust reversing systems.
