Patent number: 7712789Abstract: 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.Type: GrantFiled: July 25, 2005Date of Patent: May 11, 2010Assignee: Airbus Deutschland GmbHInventors: Gunnar Heuer, Carsten Ohlfest

Patent number: 6681412Abstract: 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.Type: GrantFiled: August 30, 2002Date of Patent: January 27, 2004Assignee: Airbus Deutschland GmbHInventors: Martin Doss, Wolfgang Erdmann, Carsten Ohlfest
