Abstract: An arrangement for conveniently collecting waste material from pet animals in a household which includes the use of a housing with a detachable cover and containing a receptacle for receiving the waste material which receptacle is filled with water, and oil on top of the water, to prevent unpleasant odors from escaping from the receptacle.

Abstract: A self-contained sewage waste disposal system including a housing structure and a toilet bowl adapted to receive human waste and fluid for diluting the waste, transporting the waste and rinsing the bowl. A removable filter cassette is in the housing in communication with the toilet bowl. The bowl is flushed and the contents are dumped into the filter cassette and the bowl is subsequently refilled. Filters in the cassette separate the coarse and fine particles of solid material from the fluid received from the bowl. The solid material is stored in the cassette in a compact manner for subsequent disposal upon removal of the cassette. Fine filtering and decoloring is accomplished by a carbon canister. A reservoir is provided for storage of fluid after removal of solid material therefrom in the cassette.

Abstract: A self-contained sewage waste disposal system including a housing structure and a toilet bowl adapted to receive human waste and fluid for diluting the waste, transporting the waste and rinsing the bowl. A removable filter cassette is in the housing in communication with the toilet bowl. Structure is provided for flushing the bowl and dumping the contents into the filter cassette and for subsequent refilling of the bowl. A filter is in the cassette for separating the particles of solid material from the fluid received from the bowl. The solid material is stored in the cassette in a compact manner for subsequent disposal upon removal of the cassette. Pumps and interconnected conduits are in the housing to transport fluid directly from an external source to fill the bowl after a flush, to transport and recirculate filtered fluid through the system for further waste disposal treatment, and to direct the effluent fluid from the system thereafter.

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 sewerless recirculating toilet and human waste storage system wherein human waste products and a flushing fluid of a specific gravity less than water are received from a commode, the waste products are separated from the flushing fluid, the separated waste products are stored indefinitely without additional treatment in a state of suspended animation for possible subsequent by-products recovery therefrom and the separated flushing fluid is stored on top of the separated waste products until a portion thereof is recycled back into the commode in a purified state for flushing the commode.

Abstract: An improved oil toilet for use with an oil-based flushing fluid including a commode having a bowl portion of the wash-down type having a generally concave inner surface and a flushing manifold at the top thereof. The inner surface is in fluid communication with a trapway having a trap seal therein leading to a discharge outlet. Overflow means are provided intergral with the inner surface for returning overflow from the bowl portion back into the dishcarge outlet. A trap seal is associated with the overflow means for sealing off odors from the discharge outlet. Fluid communication is provided between the trap seal in the overflow means and the manifold for replenishing the oil in the trap of the trap seal in the overflow means.

Abstract: A sewage system in which the transport medium or flush medium is a liquid having a specific gravity less than that of water. The flush medium after transporting sewage waste to a tank or the like thereafter separates from the sewage and floats on top of it becoming available for reuse.

Abstract: A method for preventing a flushing oil used in recirculating toilets from turning yellow and having an offensive odor when contacted with animal waste products containing, among other things, water, carotene, bilirubin, oil soluble unsaturated fats, ammonia, amines and amides such as urea which includes the steps of mixing with said waste products a water-soluble compound having an active chlorine atom whereby said water-soluble chlorine compound is dissolved in the water contained in said waste products and reacts with the ammonia, amines and/or amides to form an oil soluble N-chloro-amine or amine (particularly NCl.sub.

Abstract: A two phase recirculating sanitary system is described in which the flushing fluid phase is temporarily stored in the toilet bowl while the waste phase in the storage tank is being drained. A controllable valve is inserted between the toilet bowl and the waste tank. Prior to draining the waste tank, the controllable valve is closed and the flushing fluid phase is pumped into the toilet bowl where it is stored. The waste tank is then drained and all waste material is removed. The controllable valve is then opened releasing the flushing fluid to cover the bottom portion of the waste tank and the system is ready for use.
