Abstract: A device for locking a door kinematics system of the door of an airplane includes a control unit, an actuator for actuating a locking system and an automatic reset device. The control unit actuates the actuator as a function of the existence of a predetermined signal so that the actuator brings the locking system in a locking position. The reset device, if required, brings the locking system autonomously into a release position.

Abstract: A supporting arm of a passenger door of an aircraft, has a curved structure which forms hollow chambers and movably connects the passenger door to a frame on the fuselage. Receiving means one for the supporting arm for receiving connecting means which enable a movable connection on the one hand to the passenger door and a pivoting drive and on the other hand to the frame on the fuselage, so that the door is movable by means of the supporting arm on a linear-displacement path and a pivoting path. The structure of the supporting arm is formed from fiber composite, the structure-forming fiber composite being formed from individual structural elements. This fiber composite structure further improves the thermal insulation of the supporting arm and nevertheless achieves a further weight reduction of the supporting arm, while maintaining exacting structural safety requirements for the latter.

Abstract: An arrangement for controlling the closing and opening operation of an aircraft passenger door includes electromechanical actuators and manual actuators for moving the door and for actuating the various latching and locking mechanisms of the door, a door control unit, as well as an actuator control unit, an operating console, and sensors that sense position and status conditions of the door, all connected to the door control unit, a power supply, and power switches connected serially between the power supply and the actuator control unit. In an operating method, the door control unit controls the actuator control unit, and can switch all of the individual function steps for opening or closing the door selectively between being manually controlled and being electromechanically controlled. While the door can be actuated electrically, in the case of a malfunction or if desired by the operator, it can be operated fully or partly mechanically under a manual control.

Abstract: A door system, particularly for a passenger plane, includes bearing and guiding device which operates between the door leaf and the door frame, as well as a lifting device which is arranged between the bearing and guiding device and the door leaf. The lifting device moves the door leaf at the end of the closing movement transversely to the moving path (B) of the guiding device with a form-locking engagement with door-frame-fixed receiving elements into the completely closed position and, at the start of the opening operation, in the opposite lifting direction (A) out of the form-locking engagement. The lifting device contains lifting kinematics for the control of the door blade lifting movement and an assigned lifting drive.

Abstract: A drinking vessel is made up of an inner glass beaker part and a holder placed round it for lifting the beaker to the mouth. The holder is made up of a ring and a handle formed thereon in a single piece of material. The ring has the function of elastically gripping the side wall of the beaker. The handle has two rests which are kept elastically pressed against the beaker wall at two different levels where the conical beaker has two different diameters. The upper rest has a ledge for resting against the top rim of the beaker and locking the beaker in position in the holder axially.

Abstract: A carrier membrane supports area covering solar cells and, preferably, is used for energy supply on a spacecraft. The membrane is stretched in a frame between two opposite sides and consists of plastic sheeting covered by a fiber-reinforced plastic fabric. To save weight, prevent insulation problems and thereby increase service reliability, the fabric is made of plastic reinforced with aromatic polyamide fibers in the form of woven crossing bands. The bands extend in the direction in which the membrane is stretched and transversely of the stretched direction.
