Abstract: An aircraft window shade speed control system which allows the coordination of window shade movement speed throughout an aircraft using a single set-point device for each window shade. Each window shade is moved by an electric motor, and its travel is limited by upper and lower limit switches. Voltage is applied to each motor by a motor control module that is relatively insensitive to variations in aircraft electric buss voltage and motor current requirements. A remote operation switch allows the pilot of the aircraft to open or close all window shades in the aircraft simultaneously, and to be assured of their ultimate position by observing only the window nearest his own position.

Abstract: A fastener system to join lightweight panels such as honeycomb or foam core panels. The fastener system comprises a unique hollow, threaded fastener pin (12) and drive assembly (18). The drive assembly (18) attaches to an electric drill and is made up of a cartridge housing (14) for carrying a disposable, dual piston (epoxy resin and hardener) cartridge (20), and a plunger assembly, clutch mounted to the cartridge housing (14). The nose (62) of the cartridge (20) is adapted to receive the proximal end of the pin (12). The plunger assembly (16) mounts to the chuck of the drill. The panels are aligned and the pin (12), mounted to the nose (62) of the cartridge housing (14), is placed against the panels at the point to be joined. The drill is activated and the pin (12) is threaded in until its flared, distal end (26) is seated flush against the skin of the panel.

Abstract: A sliding pocket door adapted for aircraft use comprising two generally tabular door segments each laying in a common sliding plane and each attached to a carrier frame which is mounted to an aircraft bulkhead. Each door segment is attached to its carrier frame by unique hinges that allow the door segment to rotate out of the sliding plane while simultaneously dropping along their axes of rotation. This rotation will allow a non-destructive depressurization of the doors, for example during rapid decompression in the aircraft.
