Abstract: A waterless flush toilet system comprising a toilet and a gravity fed waste holding tank. The system utilizes a recirculating nonaqueous flushing fluid which is stored within the holding tank. The fluid, which is lighter than the waste material and insoluble therein, forms a stratified layer on the surface of the material. A float having a flushing fluid inlet floats within the layer of fluid, separated from solid waste matter by a tubular screen member, the float being suspended from the top of the tank by a flexible coiled hose which is coupled to the fluid inlet. The coiled hose contracts as the waste level in the tank rises, thereby permitting the float to remain within the flushing fluid layer regardless of the waste material level. When the toilet is flushed, an air-powered pump draws a fraction of the fluid into the fluid inlet of the float, through the flexible hose and finally to the toilet. The fluid serves as a medium for transporting the waste material from the toilet to the holding tank.

Abstract: A waterless flush toilet system comprising at least one toilet and a gravity fed waste holding tank. The system utilizes a recirculating nonaqueous flushing fluid which is stored within the holding tank. The fluid, which is lighter than the waste material and insoluble therein, forms a stratified layer on the surface of the material. A float having a flushing fluid inlet floats within the layer of fluid, the float being suspended from the top of the tank by a flexible coiled hose which is coupled to the fluid inlet. The coiled hose contracts as the waste level in the tank rises, thereby permitting the float to remain within the flushing fluid layer regardless of the waste material level. When the toilet is flushed, an electric or air-powered pump draws a fraction of the fluid into the fluid inlet of the float, through the flexible hose and finally to the toilet. The fluid serves as a medium for transporting the waste material from the toilet to the holding tank.

Abstract: A water economizing system for new or existing buildings where the waste lines of lavatory sinks, showers and clothes washing machines are connected to a storage reservoir for accumulation of water therein. This accumulated water is filtered and treated and thereafter used for the operation of water closets of toilets, the storage reservoir providing for the removal of solids and foam by flushing action at the top and subsequently by the gravitational separation of solids which are periodically flushed from the bottom of the reservoir into the sewer. The pumping action which delivers the accumulated water to the water closets of toilets may optionally be hydraulically operated by a portion of the water drained to the storage reservoir.

Abstract: An improved sanitary water closet wherein the soil pipe leading to the sludge tank, passes through a flushing container and is formed inside the latter with a bend provided with grid means arranged to allow passage through of liquid into the container and further to a septic tank, but to divert solid material to the sludge tank. Because of the separation of liquid and solid products, the sludge product obtained in the sludge tank contains very little moisture and is therefore easily biologically degradable.

Abstract: A lavatory bench, or toilet, in which solid wastes are collected and biologically decomposed. The bench comprises a container beneath the seat and near the top of the container is a rotary member to which material is supplied and which, while rotating, distributes the material within the container. The container is advantageously heated. A casing is provided which supports the seat and which surrounds the container and from which there leads a lead stack, or outlet pipe. The rotation of the aforesaid member causes air circulation within the device and promotes the movement of air out through the outlet pipe. The rotatable member near the top of the container also serves the function of shutting off the inside of the container from view.

Abstract: A vacuum flush waste disposal system for aircraft; wherein, the required vacuum is acquired at altitude through the differential pressure between the aircraft cabin pressure and the ambient pressure above approximately 15,000 feet. When the aircraft is below this altitude or on the ground, the vacuum is provided by a blower. For flushing the toilet bowl, a timing device is initially actuated and functions: to introduce a recirculated flush fluid into a flush ring in the upper portion of the toilet bowl; and to open a drain in the lower portion of the toilet bowl, leading to the vacuum waste line; whereby, the waste and flush water are rapidly propelled through the waste line towards a centrally located holding tank, by the differential pressure acting upon it. Once in the holding tank, the waste fluid is filtered out for further use as the recirculated flush fluid.

The solid transfer system includes a grinding, material moving mechanism located at the lowermost area of the solid disposing portion of the bowl. The mechanism is positioned on the vertical centerline of the solid disposing portion of the bowl. The mechanism grinds the solid materials and forces or pumps the ground solid material into a solid transfer conduit to store solids in a distant, generally sealed, collecting tank that is open to atmosphere.

Abstract: A bedpan liner, kit and method is disclosed which allows reuse of a conventional bedpan without sterilization, and provides for clean efficient handling of bedpan wastes. The liner is a sheet of water impermeable flexible plastic material which is gathered at opposite ends and secured in the gathered condition to form an elongated hammock-like pouch with relatively rigid end portions suitable for handgripping to carry and dump the pouch. The pouch or liner has convoluted walls that can be approximately formed to the basin in a bedpan. Adhesive tabs attached to opposite ends of the pouch serve to temporarily secure the pouch to the bedpan. Tissue like paper napkins, separable from the pouch, absorb fluid wastes, reduce malodor and conceal the wastes from a person utilizing the liner, kit and method. After removing the liner from the bedpan, tension applied between the ends thereof causes the walls to contract and hold the wastes in a sling or hammock-like manner.
