A wastewater tank arrangement for an aircraft, including a wastewater tank and a drain pipe having a first end and an opposite second end, the drain pipe fastened with its first end to the wastewater tank and having a second end for connection to a service panel in the aircraft structure. Providing a wastewater tank arrangement can effectively compensate tolerances between the wastewater tank and the service panel, and can effectively compensate installation and manufacturing tolerances during the course of the initial installation, in that the wastewater tank arrangement has a tolerance compensation device configured to connect the second end of the drain pipe to the service panel and compensate tolerances between the second end of the drain pipe and the service panel.

An arrangement for adapting the transportation behavior of material to be conveyed includes a first container, which is coupleable to a first pressure level; a second container, which is coupleable to a second pressure level; a connecting line for transporting material to be conveyed from the first container to the second container; and a pressure reduction device by which a pressure difference between the first container and the second container is controllably variable.

Arrangement for noise reduction in vacuum systems

The present invention relates to an arrangement for adapting the transportation behavior of material to be conveyed, which arrangement comprises a first container, which is coupleable to a first pressure level; a second container, which is coupleable to a second pressure level; a connecting line for transporting material to be conveyed from the first container to the second container; and a pressure reduction device by means of which a pressure difference between the first container and the second container is controllably variable.

An adapter for coupling connecting pipes for a commercial aircraft comprises an adapter top and an adapter bottom. The adapter bottom has a first adapter pipe that can be positioned within a recess in a floor of the aircraft. An attachment flange is formed to the external circumference of the first adapter pipe, through whose central flange opening the first adapter pipe is led, which attachment flange is positioned on the first adapter pipe end of the first adapter pipe and is attached by one flange side to a bottom floor region of the floor. The adapter top has a second adapter pipe to which a tubular supporting flange is joined. The pipe end region reinforced with said supporting flange of the second adapter pipe is inserted into the pipe cross section of the first adapter pipe.

A filter arrangement for a vacuum toilet system includes a filter element arranged in a filter housing connected to a waste water tank of the vacuum toilet system. The filter element includes a polytetrafluoroethylene (PTFE) filter membrane on the inlet side thereof, a filter support material supporting the PTFE membrane, and a support cage, to form a filter cartridge. The filter is preferably a pleated cylindrical filter with the inlet side on the inside of the cylinder. The arrangement preferably further includes a rinsing nozzle that rinses contaminants from the inlet side surface of the filter element, to flow down into the waste water tank. This rinsing, together with the low adhesion and the surface filtration principle of the PTFE filter membrane, prevent clogging of the filter.
