Abstract: In an anti-hijacking system for autopilot equipped aircraft, a transceiver communicates with at least one remote guidance facility. A panic button is activated by flight crew in case of hijacking. A manager is coupled to the transceiver and the panic button, as well as existing avionics including the aircraft's master computer and autopilot. Optionally, a relay is coupled between the pilot controls and selected aircraft flight systems. The manager recognizes predetermined override inputs, such as activation of the panic button or receipt of override signals from the remote guidance facility. Responsive to the override input, the manager deactivates on-board control of selected aircraft flight systems and the autopilot system, and directs the autopilot to fly the aircraft to a safe landing. Flight routing and landing instructions are obtained from the remote guidance facility, or by self-evaluating nearby airports in view of the aircraft's position and various preestablished criteria.

Abstract: An improved drum closure assembly which includes a ring member and a cover member, the cover member being cooperatively sized for a fitted, overlapping relationship with the ring member. The ring member comprises outer and inner ring portions which are angularly displaced from parallel to one another. The cover member includes a top cover member and an annular wall member designed to about the outer ring portion of the ring member and to seal the assembly when in use.

Abstract: Apparatus for positioning a chime ring member of a drum closure assembly into an interference, fitted relationship, with a fibre drum. The apparatus comprises a support frame and a sliding head assembly mounted on the support frame. The sliding head assembly includes a chime ring retaining member. A drum support assembly is also mounted on the support frame and includes a first and second drum retention means. The first drum retention means prevent movement of the drum during positioning of the chime ring member while the second drum retention means guides the concentric expansion of the top portion of the drum. Means are also provided for actuating movement of the sliding head assembly as well as a source of power for supplying energy to the sliding head assembly.

The ring member comprises outer and inner ring portions which are angularly displaced from parallel to one another. The cover member includes a top cover member and an annular wall member designed to abut the outer ring portion of the ring member and to seal the assembly when in use.

Abstract: A continuous flexible hinge for paperboard and the like, suitable for use in making book cover blanks, is skived in the region beneath the hinge tape to a depth equal to the thickness of the tape. The hinge tape and paperboard are assembled with the hinge tape adhered in the groove in the skived region, leaving the tape flush with the surface of the paperboard.

Abstract: A negatively pressurized rotating hollow foil pulse device having a curved leading surface, a V-shaped trailing surface and one or more openings in the trailing surface is placed in close proximity to a pulp screen for removing oversized pulp reject material. A rotating disc seal separates a reject compartment from the material to be screened.
