Abstract:
A drainage system for an aircraft is taught herein. The drainage system includes a drain tube defining an orifice. The drainage system further includes a cover movable between a first cover position and a second cover position. The cover is configured to overlay the orifice when the cover is in the first cover position. The cover is configured to expose the orifice when the cover is in the second cover position. The cover is configured to move between the first cover position and the second cover position in the presence of air pressure.
Abstract:
The invention relates to a suction device (1) for removing a mixed fluid, in particular fecal matter, from a collecting tank (2), in particular from a sewage tank of a railway vehicle, comprising a mixed fluid inlet (4) for receiving the mixed fluid, said mixed fluid inlet (4) being fluidically connectable to a connection port of said collecting tank (2), a mixed fluid outlet (8) for discharging the mixed fluid, said mixed fluid outlet (8) being fluidically connectable to a suction line, and a flow channel (14) extending between said inlet and said outlet.The invention relates in particular to a constriction member (10) which is adapted to reduce a cross-section of the flow channel (14) in sections thereof or along the entire length thereof.The invention further relates to a suction station for removing a mixed fluid, and to such a method.
Abstract:
The invention relates to a method for operating a tank for receiving fluids in a sanitary system of a rail vehicle, wherein a) the fill level of the tank is registered; b) in the event that the fill level registered in step a) is equal to or greater than a fill level specified for the tank, ice formation is permitted for a time period specified for the tank; c) in the event that the fill level registered in step a) falls below the specified fill level, the tank is emptied; or d) in the event that the fill level registered in step a) falls below the specified fill level, the fill level is increased with fluid from a fresh water tank, and subsequently, steps b) or c) are carried out.

Abstract:
The present invention relates to the treatment and disposal of waste, including sanitary, petroleum, and other organic wastes. More specifically, the present invention treats and disposes of these types of waste from portable and remote waste generating sources, such as passenger carrying vehicles and remote facilities where sewage and septic systems are impractical. The invention makes use of thermal energy liberated from devices that generate a hot exhaust stream, such as internal combustion engines. The invention generally involves the passing of a waste material from a tank through a homogenizing device. The homogenizing device reduces the particle size and thoroughly mixes the waste stream so that it maybe injected into a hot exhaust stream, which converts the waste stream into water vapor, gas and inert ash.
Abstract:
An effluent disposal apparatus for railways includes a storage tank adapted to be fitted to a railway vehicle. The tank has an inlet for receiving effluent, an outlet for release of the effluent stored in the tank, and an effluent release valve movable between a closed position in which the effluent is prevented from passing through the outlet, and an open position in which the effluent is allowed to pass through the outlet. A controller controls operation of the valve in response to an effluent release signal generated by a release signal generator to automatically open the release valve to release the effluent from the tank when the vehicle is at a predetermined position with respect to an effluent receptacle located under or alongside the track.
Abstract:
A waste holding tank for a mobile sanitary toilet system includes a base section, a bowl section supported by the base section and a waste holding tank. The tank includes a housing defining a tank interior and a tank exterior. A vent opening is located at a first location of the housing. The opening forms a fluid communication between the interior and the exterior of the tank. A vent conduit connects the vent opening on the tank exterior at the first location with the exterior of the tank at a second location of the housing. The vent conduit leads at least partly through the interior of the tank without being in fluid communication with the interior of the tank.
Abstract:
A vacuum toilet system comprises a plurality of toilets, a collecting tank, a conduit system that connects the plurality of toilets with the collecting tank, and a vacuum generator that is connected in a fluidic manner to the collecting tank. The conduit system further comprises a main duct and a plurality of branch ducts, via which the plurality of toilets are connected to said main duct and which discharge into the main duct at an acute angle formed with a component that is pointed in a delivery direction in the main duct, wherein the branch ducts describe curved sections adjacent to a respective inflow thereof having a curvature mid-point of a respective mid-line of the curved sections of the branch ducts being located behind a respective inflow point of a center line in the main duct with regard to the delivery direction in said main duct.
