摘要： A vacuum tank assembly has a low volume configuration so that it can be used in boats and recreational vehicles where space is at a premium. A stack of components, with a waste tank at the bottom, then a vacuum tank with directly connected vacuum pump, and one or more fresh water tanks, is located remote from a vacuum toilet, with a discharge from the toilet (below a vacuum-tight ball valve) connected to the vacuum tank, which is in turn connected to the vacuum pump, in turn connected to the waste tank. A submersible centrifugal pump may be provided mounted to a cap of the water tank, with an anti-siphon device associated with it. The vacuum tank is of high density polypropylene having flat walls, with no continuous flat surface more than 80 square inches. Lipless duckbill check valves are provided on opposite sides of the vacuum pump, the valves of elastomeric material having a ratio of the wall thickness to thickness of the sealing edges of about 1:1. The waste tank may have a dip tube with a dog leg portion having a large cross-sectional are oval bottom opening to minimize the possibility of clogging.

摘要： Flexible PVC hose can be used with toilet systems in vehicles, such as boats, recreational vehicles, etc, or at pumpout stations. The hose includes about 40-55% by weight PVC resin, and at least 10% by weight of an EVA high molecular weight plasticizer. The hose also typically includes a low molecular weight plasticizer, stabilizer, lubricant, filler (such as 5-20% by weight dense filler like calcium carbonate), and pigment. The hose typically will not fail (that is will not transmit odor) for the life of the toilet system, or mechanical life of the hose.

摘要： A sewage handling assembly particularly for boats and recreational vehicles with a minimum of components. The waste discharge of a toilet is connected to an inlet for a combined vacuum and holding tank which mounts a vacuum pump, and optionally mounts a sewage discharge pump. A sewage discharge conduit, which may be connected to the optional sewage discharge pump, is connected to a first outlet from the tank, in turn connected to a dip tube terminating in an open end just above the tank bottom. A second outlet from the tank is connected to the vacuum pump (in turn connected to a gas conduit with an end termination penetrating an exterior partition of the boat or RV), and an upwardly extending gas tube inside the tank, having an opening near the interior top of the tank, is connected to the second outlet. The tank is controlled so that a gas volume of about 2 and 1/2-4 gallons is always maintained in the tank, with a vacuum level of between about 8-10 inches of mercury. Once the volume of sewage in the tank reaches a predetermined level--so that sewage might be inadvertently withdrawn by the vacuum pump--the vacuum pump is controlled so that it will not operate until the tank is emptied (or the sewage level otherwise reduced).

摘要： A sanitation system, particularly for use in vehicles such as marine vessels (boats), trains, planes, etc. Into a holding tank with a sloping bottom containing sewage from a toilet system, such as a vacuum toilet system, about eight ounces of deodorant chemical is automatically injected into the tank approximately every 48 hours. This effectively controls odors while minimizing chemical consumption. A gas vent from the tank passes through a vent filter having a first type of activated charcoal effective against H.sub.2 S, and a minor amount of activated charcoal effective against amino acid gaseous compounds, the vent filter removing odors. A tank cap in the top of the cap supports "high" and "full" level indicator switches and allows for the injection of the chemical and the gas vent. A tank cleaning device comprising a piece of surgical tubing with a nozzle at its free end and connected to a source of liquid under pressure can also be utilized. In use, the nozzle impacts the tank walls while spraying liquid in it to effect cleaning. A control module and control panel provide for an indication of the tank liquid level, control of the injector pump, and control of the discharge pump which discharges sewage from the holding tank.

摘要： The emptying of the contents of a holding tank for a recreational vehicle or the like into a land based water closet is greatly simplified, and made much less unpleasant. A portable tank has wheels at one end and a handle at the other, with a discharge valve located adjacent the handle. A deployable stationary support is provided with the tank. The deployable support includes collars engaging stub shafts extending outwardly from the sides of the tank, and two sets of legs which provide a supporting base. As the tank is moved into a vertical position it moves to a point where it is no longer supported by the wheels, but instead is supported by the legs, and the connection between the tank and the legs is automatically unlatched. The tank is then tilted (pivoted) about a horizontal axis so that the discharge valve is right above a water closet. A tube extends from the valve into the toilet to about the point of the liquid level. The valve is then opened from an area adjacent the wheels, and the contents of the tank are discharged into the water closet with a minimum of splashing and in a manner that automatically prevents overflow of the water closet. A pop up level indicator and manually operated vent are also preferably provided in the tank.

摘要： A toilet (10) and toilet system suitable for a boat, recreational vehicle, bus or the like is operated via a microprocessor controller to effect a convenient and efficient operation. The toilet includes a base assembly (30) having an electrically-operated flush valve that opens and closes a passage to a waste receiving area. A flush lever assembly (15) has flush lever displaceable from a neutral position toward one of a “flush” position and an “add water” position. In this context, the flush lever initiates a flush cycle in the “flush” position and initiates an add water cycle in the “add water” position. The controller communicates with a water inlet valve, the flush valve and the flush lever assembly. In operation, the controller opens and closes the water inlet valve and controls a position of the flush valve in accordance with a position of the flush lever.

摘要： The unpleasant task of manually removing a sewage holding tank from a recreation vehicle at a campground, and emptying it, is avoided by operatively connecting the RV sewage system to a stationary (preferably underground) vacuum installation at the campground. While the RV is renting space at the campground it is connected to an above ground vacuum hookup (typically including a conduit and a shut-off valve, and usually also a flexible hose with a dripless free end connection), at a campsite. The hookup is, in turn, connected to at least one underground vacuum source. The vacuum source may be a vacuum pump connected to a number of vacuum tanks (one for each hookup), with a check valve (e. g. duckbill valve) isolating each vacuum tank from the others. Alternatively, the vacuum source may be a vacuum generator connected to each hookup, and a common gravity sewer pipe connected to all of the vacuum generators.

摘要： A marine tank (such as a toilet system holding tank, or bilge tank) pump out system includes a positive displacement pump connectable at the inlet to a marine tank to be pumped out and connectable at the outlet to a discharge tank or area. A pulsation dampener is connected between the pump outlet and the discharge tank or area, preferably directly to the pump so that a pump check valve is within the pulsation dampener. The pulsation dampener has an open chamber extending upwardly from the pump outlet into which pumped fluent material may flow, and has no moving parts (such as a diaphragm). Typically two different outlets from the dampener are provided for versatility and connecting up to discharge tanks or areas, one of the outlets filled with a plug. The dampener may comprise either a substantially L-shaped or C-shaped (when viewed from the dampener inlet) casing, which nests with the pump motor.

摘要： Hose samples are tested to determine their permeability to noxious odors when used to conduct sewage. A hose sample is preferably pre-treated with methyl alcohol for several days to accelerate the rate of failure. Then the open ends of the hose sample tubular body are sealed and the tubular body is covered with a flexible generally (although not necessarily completely) sulfur-containing gas-impervious material (such as nylon film) to define a gas volume between the exterior surface of the hose and the film. Carbon disulfide, dimethyl sulfide, and/or dimethyl disulfide are introduced into the interior of the hose and allowed to stand for at least a day, and then the content of any gas in the gas volume between the exterior surface and the hose is evaluated to see if it is gas from carbon disulfide or like fluids introduced into the hose. Typically evaluation is done by making a slit in the gas impervious material just large enough for an end of a detector tube, hooking the detector tube to an evacuating pump, operating the evacuating pump to draw gas from the gas volume into the detector tube, and analyzing the withdrawn gas for carbon disulfide, etc. The slit may be resealed with the self-adhesive tape.
