Abstract: Provided is a method for the production of a crosslinked molded body containing polyaryletherketone (PAEK), comprising the steps of (a) providing a mixture comprising a PAEK and a crosslinker, (b) preparing a molded body from the mixture, and (c) thermally treating the molded body at a temperature at which PAEK crosslinks, thereby obtaining the crosslinked molded body, and wherein the crosslinker is a di(aminophenyl) compound comprising two aminophenyl rings, wherein the two aminophenyl rings are joined together via an aliphatic group having a carbocyclic rest.

Abstract: A system for delivering breathing gas to passengers on-board an aircraft, including: a source of breathing gas, at least one face mask for passengers, a reservoir associated with each face mask, a delivery valve for each face mask, the delivery valve being disposed between the source of breathing gas and the reservoir, the reservoir being disposed between the delivery valve and the face mask, a sensor associated with each reservoir and configured to sense a filling of the reservoir, and a controller configured to control the delivery valve in a continuous supply mode to provide a continuous flow of breathing gas to the reservoir and to interrupt the continuous flow of breathing gas when the filing sensed by the sensor is a filling threshold.

Abstract: An oxygen supply system for an aircraft includes a control valve, a reservoir bag, a respiration device and a sensor device, wherein the control valve is designed in such a way that oxygen can be supplied to the reservoir bag until a predetermined quantity of oxygen is adjusted in the reservoir bag. The respiration device may be designed in such a way that breathing gas can be provided for a passenger. The sensor device may be designed in such a way that an exhalation is detectable. The reservoir bag may be designed in such a way that a predetermined quantity of oxygen can be metered into the reservoir bag during the exhalation. The reservoir bag may be designed in such a way that breathing gas can be supplied to the respiration device in a pulse-like fashion. The oxygen supply system may include a first and a second operation mode.
