Abstract: A toilet has an electronic flush assembly operable in either a short or long flush sequence selectable by a user. The long flush sequence includes a pre-rinse cycle and a rinse cycle in which the a supply valve and a flush valve are both opened and closed twice, once each first during the pre-rinse cycle and again during a subsequent rinse cycle. The rim supply valve and the flush valve are opened during the pre-rinse and rinse cycles but are closed at the start and end of each cycle. An electronic control controls operation of the valves as well as water supply control components. Level sensors can also be included to provide feedback to the controller, for example, to prevent overflow conditions.

Abstract: Tilting Bowl Toilet comprises a frame, a toilet basin, and a tilting bowl. The tilting bowl is supported below the toilet basin to receive and hold water/waste delivered from the toilet basin. The tilting bowl tilts to discharge its content to drainage. The tilting bowl at standby is sustained to stay in a horizontal position by a sustaining turning moment about its support axis. When water is added, the turning moment produced by the tilting bowl with its content becomes larger than the sustaining turning moment, and the tilting bowl moves to a tilted position to discharge its content. As the tilting bowl tilts, the sustaining turning moment is simultaneously reduced to accelerate bowl tilting for efficient discharge of waste to sewage.

Abstract: A toilet includes a bowl with a receptacle to receive waste, with a secondary chamber, and with an opening in the receptacle to allow the waste to pass to the secondary chamber; a rinse pump that turns on to add an amount of rinsing water for cleaning the bowl; a flexible self cleaning gasket configured around the opening formed in the receptacle; a bowl valve that has a sealing part having a rounded shape, rotates to a closed position that creates a sealed effect between the sealing part and the gasket trapping the waste and rinsing water in the receptacle of the bowl and sealing odors in the secondary chamber, and also rotates to an open position that sweeps the sealing part to be swept across the gasket and allowing the waste to pass to the secondary chamber. The solenoid rotates the bowl valve between the closed to open positions.

Abstract: Disclosed are trap valve assemblies for controlling flow from a toilet bowl to a trap way. In one form there is a cartridge unit positionable immediately below a toilet bowl discharge outlet. It has a pivotable gate in a form of a spherical segment. The gate has an eccentric pivoting motion so that it can swing from an open position to a blocking/closing position in which it fully contacts a sealing gasket. The spherical segment has a leading edge which is approximately between +40° and ?40° from vertical when the gate is in an open position, to minimize the energy required to close the gate. In another form a ball and socket connection to the gate valve facilitates sealing.

Abstract: Tilting Bowl Toilet comprises a frame, a toilet basin, and a tilting bowl. The tilting bowl is supported below the toilet basin to receive and hold water/waste delivered from the toilet basin. The tilting bowl tilts to discharge its content to drainage. The tilting bowl at standby is sustained to stay in a horizontal position by forces applied to the tilting bowl creating a resultant sustaining turning moment about its support axis. When the turning moment produced by the tilting bowl with its content becomes larger than the sustaining turning moment, the tilting bowl moves to a tilted position to discharge its content. The effective support axis shifts with respect to the tilting bowl as guided by a motion guide.

Abstract: A gravity drop-toilet uses main water via electronically programmed valves to rinse separate areas of a bowl (71) in sequence via appropriately located and pointing jet orifices (136, 138,140) with about 70% less water than siphon toilets. Electronically timed valve (180) hydraulically causes a pair of bellows (110) to compress and expand and thereby reversibly pivot a mechanical linkage to retain waste in the bowl and drop waste via a vertical waste passageway into a sewer pipe (30). The linkage comprises a transfer arm (118) that pivots a rotating arm of a cup (128) and flap actuating arm (104) to pivot a springy plate (78) upward against a dimple (80) formed on under the side of the flap (30) which thereby aligns itself against the bottom edge (74) of the bowl (71). A urine version of this mechanism uses apertures (174, 175) that they enclose combine to center defecating sitters over a cylinder outlet (48) of the bowl.

The toilet unit includes a plastic toilet bowl having an interior surface, open top, and exterior surface, a plastic body positioned exteriorly of the toilet bowl exterior surface, and a plastic toilet seat for partially closing the open top of the toilet bowl. To enhance the longevity and effectiveness of the toilet bowl without significantly increasing the cost and weight of the toilet unit, a layer, coating, or thin walled insert liner made of a non-polymeric substantially poreless material that is not degraded by contact with excrement, light, or toilet bowl cleaning agents, is disposed interiorly of the plastic toilet bowl and is at least partially supported by the plastic toilet bowl and may comprise porcelain, glazed ceramic, glass, corrosion resistant sheet metal, or sheet metal with a corrosion resistant poreless interior coating.

Abstract: The toilet with a deflector shield covering the flush nozzle to deflect a portion of the flush water. The deflected water flows downward to wet the bowl in the area beneath the flush water nozzle. The undeflected water flows onto a ledge at the upper end of the bowl and flows around the bowl where it gradually falls off the ledge and wets the remaining portion of the bowl. Both a foot pedal and a hand lever are provided for flushing the toilet and a cable is used to couple the foot pedal to the hand lever. The hand lever is operably connected to the flush water valve as well as the bowl discharge opening closure member to open both for flushing of the toilet.

Abstract: The noise developed in a suction toilet system, for example in an aircraft, by the activation of a suction valve is substantially reduced by generating the required suction with the aid of two valves, one of which is a by-pass flow valve that can be arranged away from the toilet bowl itself. The air supply for the by-pass flow valve is provided through a noise damper, whereby a substantial reduction in the noise is achieved. The by-pass flow valve is connected to the conduit that connects the bowl to the collecting container with a T-coupling near the container.

Abstract: A vacuum sewer arrangement comprises a valve controlled air inlet duct to let air into the vacuum sewer at a position downstream of the sewer valve. The sewer valve can then be closed immediately after the sewage has passed into the vacuum sewer, because the air required for the sewage transport is received from the air inlet duct. Hence, the amount of air that flows into the sewer through the sewer valve when the sewer valve opens is small, and when the sewer valve is closed, air flows through the air inlet duct into the sewer, which reduces the pressure difference acting on the sewer valve. These measures tend to considerably reduce the noise level. In the case of a vacuum toilet sewer arrangement, the noise level can be further reduced by providing the toilet bowl with a lid forming a substantially airtight and soundproof closure at the top of the bowl.

Abstract: The invention relates to a device for preventing communication through pipe lines of high security institutions. A flapper valve is provided with a valve seat having a plurality of teeth extending into the center of the opening formed in the valve seat. A pivotal flapper opens or closes the valve by abutting a seating face of the valve seat or moving away, under the force of a fluid flow, and allowing passage of waste water from a plumbing fixture to the main waste conduit. A water trap seal is optionally and/or separately mounted for delivering an additional amount of water into the conventional waste trap to fill in the waste trap with fluid and prevent undesirable communication. An independent conduit connected to a water supply delivers water to a reservoir which is fluidly connected with a conventional jet conduit of a waste water system upstream from an outlet point of the jet conduit into the main waste trap.

Abstract: A toilet having a foot pedal flush control comprising two pedals, one for opening a toilet bowl discharge outlet and the other for supplying flush water to the bowl. The pedals both operate through actuation cables having a wire member slidable within a conduit. The flush water pedal can be independently actuated to partially fill the bowl prior to use of the toilet while the outlet closure member pedal coacts with the flush water pedal so that upon opening of the bowl outlet, the flush water pedal is depressed providing water to the bowl. The wire members are solid wire members coupled to the pedals for both pull and push operation so that upon a failure of the pedal return mechanism, the pedals can be manually returned closing the bowl outlet and terminating the flow of flush water to the bowl.

Abstract: A lavatory system suitable for use on a commercial passenger aircraft includes a toilet bowl for receiving waste and a waste-holding tank in fluid communication with the toilet bowl for receiving waste from the toilet bowl. A flapper valve is provided in the bottom of the toilet bowl and operates to control the passage of the toilet bowl contents into the waste-holding tank. Water, which may be from the potable water supply system, is directed into the toilet bowl to wash the sides of the toilet bowl and to assist in moving waste material to the waste-holding tank. A water inlet valve controls the introduction of water into the toilet bowl by actuation of a flushing switch. The water is introduced into the toilet bowl through a single nozzle which moves and progressively directs the flow of the water onto the entire interior of the toilet bowl in such a manner that a minimal amount of water is utilized per flush.

Abstract: A flush toilet primarily for use in recreational homes and vehicles is described. A swing drop valve mechanism is used to open and close the outlet of the toilet bowl efficiently and without abrading the seal between the valve and bowl outlet. A flush water inlet valve is mounted in a compartment at the rear of the toilet for easy access for maintenance and is readily removable from the toilet using a minimum of tools. Flushing of the toilet is initiated by a foot pedal connected to the valve mechanism and water inlet valve by cables.

Abstract: In order to save space, a bathroom appliance such as a lavatory pan, urinal, basin or bidet is mounted to turn about a pivot axis between an operative position in which the appliance is accessible for its normal usage and an inoperative position in which the appliance is retracted into a cavity within or behind the structure, e.g. wall or floor, on which the appliance is pivotally mounted. The water inlet and waste outlet to and from said appliance are connected thereto by water tight joints which each include two parts relatively rotatable about the said pivot axis e.g. rotary ring joints.
