Abstract: A device for pulsed liquid dispensing includes a feed line, a dispensing unit, and a conveying device. The dispensing unit has a rigid lance with a dispensing tube. The feed line is connected to an input side of the conveying device. An outlet connection of the conveying device is connected to the output unit. The dispensing unit includes a gripping part and a manually actuated release valve. The conveying device is a diaphragm pump, so that, once the release valve is open, the number of pump cycles correlates with the volume of dispensed liquid. This allows a predetermined amount of liquid to be conveyed without distracting the operator.

Abstract: A passenger seat comprises a carrier structure, a backrest and a seat element displaceably fastened to the carrier structure, relative to the backrest, in a depth direction of a seating surface of the seat element between a usable position and an out-of-use position. In the usable position, the seat element is arranged, relative to the backrest, so that a front edge of the seat element that faces away from the backrest is arranged at a first distance from a backrest surface of the backrest. In the out-of-use position, the seat element is received, at least partially, in a gap provided between a part of the carrier structure carrying the seat element and an edge of the backrest facing towards the seat element, the front edge of the seat element being arranged at a second, smaller distance from the backrest surface of the backrest than the first distance.

Abstract: A passenger seat comprises a backrest, a seat element and a size increasing mechanism which is configured to convert a weight acting on the seat element when a user sits in the passenger seat into an increase in the depth of a seat pan of the seat element that can be used by the user from a rest-position depth to a to an operational-position depth.

Abstract: A passenger seat comprises a backrest and a seat element that includes a first portion adjoining the backrest and a second portion that can pivot between a rest position and an operational position. In the operational position, the second portion of the seat element increases a depth of a seat pan of the seat element that can be used by the user. A locking mechanism is configured to prevent a pivoting movement of the second portion of the seat element from the operational position thereof into the rest position thereof when a weight of a user sitting in the passenger seat acts on the seat element.

Abstract: An aircraft passenger cabin area comprises a main aisle extending substantially parallel to a longitudinal axis of the aircraft passenger cabin area, a restricted area, wherein a non-encroachable safety area is defined in the region of the restricted area, a transverse aisle connecting the main aisle to the restricted area and at least one passenger seat comprising a rigid carrier structure, a backrest and a seat element and arranged in the passenger cabin area adjacent to the transverse aisle such that the seat element faces the transverse aisle. The seat element is displaceable, relative to the backrest and carrier structure, in a direction substantially perpendicular to a longitudinal axis of the transverse aisle between a usable position and an out-of-use position. In its usable position, the seat element, protrudes into the safety area, but, in its out-of-use position, the seat element clears the safety area.

Abstract: An aircraft barrier system separating, within an aircraft, a secure area from a passenger cabin of the aircraft, comprises a barrier installed inside the passenger cabin and configured to move between an open position and a closed position, a latch mounted to the barrier, and a locking device comprising a latching clamp configured to lock the latch when the barrier is in the closed position. The aircraft barrier system further comprises a release mechanism configured to move the latching clamp from a locking state locking the latch to an unlocking state releasing the latch, wherein the release mechanism is further configured to delay the moving of the latching clamp from the locking state to the unlocking state. Also, an aircraft area and an aircraft having such aircraft barrier system.

Abstract: The present invention provides a flat speaker, in particular in the aerospace sector, with a panel for generating acoustic signals by vibration of the same, and a vibration exciter which is connected to a panel and excites this to vibrate. Here the panel has an edge stiffening. This provides the panel with the required stiffness, particularly against hand pressures, but at the same it guarantees high energy efficiency of the flat speaker.
