Abstract:
Embodiments described herein relate to quick release toilet concepts, which can be useful particularly on-board aircraft and other passenger transport vehicles. Further embodiments relate to improved shroud components for toilets that help reduce splash. Further embodiments also relate to flushing systems for use with vacuum toilets.
Abstract:
Embodiments of the present invention relate generally to systems and methods for preventing mineral scale deposits in an aircraft water system, and more specifically, within devices and water transport systems, such as coffeemakers and other galley equipment, as well as the water lines themselves.
Abstract:
Embodiments of the present invention provide a filtration system that can be used to filter debris-laden water and to systems for cleaning the filtration system using a vacuum flush system to create a backwash flow through the filter of the filtration system. The filtration system described finds particular use on-board passenger transport vehicles that have a vacuum waste system, such as aircraft. The filtration system provides the ability to collect, treat, and reuse liquid resources in an environment with a vacuum waste system.
Abstract:
Embodiments of the present invention provide a system to direct water flow through a lavatory and to cleanse grey water through a series of treatment steps. The water may then be re-directed to the faucet for re-use in hand washing or other potable water use or to the toilet for flush water. The treatment steps are altered, depending upon the ultimate use of the water, as flush water need not be treated to the same level as potable water. The system may also function via a cascade of logic commands given by a series of electronic controllers, valves, and sensors which are fine-tuned to supply enough water to each component of the system.
Abstract:
Embodiments of the present invention provide integration of aircraft urinals (10) into vacuum waste systems of commercial aircraft. The urinals (10) may either be rinse versions or waterless urinals.
Abstract:
Embodiments of the present invention relate generally to multi-port orbital valves for use in controlling the direction of fluids and mixed media, and find particular use in connection with toilet systems, such as vacuum toilet systems.
Abstract:
Embodiments of the present invention relate generally to air sanitation and disinfection, and particularly to air sanitation and disinfection for aerospace applications. More particularly, it is disclosed an air treatment system, comprising:(a) a reaction chamber comprising an inlet, an outlet, and an inner reaction surface; (b) an air flow space positioned inside the reaction chamber; (c) at least one or more ultraviolet light-emitting diodes positioned inside the reaction chamber; (d) a photo-catalytic oxidative coating on the inner reaction chamber surface, wherein the inlet is configured to cooperate with an air inflow source and wherein the outlet is configured to cooperate with an air-dispensing apparatus.
Abstract:
Embodiments of the present invention provide a grey water flush system for use with vacuum toilets. One embodiment of the system provides a two-stage flush that uses a transient tank (20) in between the toilet bowl (14) and the main aircraft waste tank (18), which reduces the noise level associated with the flush process because a lesser vacuum is demanded for the first stage of the flush. Embodiments of the system further capture grey water from a sink basin (12) in a reservoir (34) and use that water in the toilet flush process. There is further provided a lavatory odor removal system (28) option that is activated during the second stage of the flush.
