| 20090000019 | WASTE TRANSPORT SYSTEM AND APPARATUS FOR USE WITH LOW WATER OR WATER FREE WASTE DISPOSAL DEVICES - A waste transport system may be used for transporting waste from low or no water disposal devices (e.g., low flow toilet fixtures, foam flush toilets and similar types of reduced water toilet fixtures) to remote areas that may not be functionally accessible by gravity. These areas may include, but are not limited to, composting units, sewers, septic systems, holding tanks or areas where the waste may be combined with additional water. | 01-01-2009 |
| 20090217448 | Human Waste System - In one aspect of the present invention, a system for the transportation of liquid and solid waste incorporated into a floor of a building has a generally horizontal pipe with a first and second end. A motor is disposed at the first end and an auger is disposed in and along at least a portion of a length of the pipe and is in communication with the motor.

| 20090300834 | System for Flushing a Vacuum Toilet and Toilet Cover for a System of This Type - A system for flushing a vacuum toilet contains a flushing water reservoir container, which may be filled with flushing water, a toilet bowl, which is connectable using a vacuum wastewater line and via a flushing valve to a vacuum system, and a spray device, situated in the toilet bowl, which is connected via a Venturi nozzle to the flushing water reservoir container. A partial vacuum is generated in the vacuum wastewater line when the flushing valve is open, which generates an airflow, by which flushing water contained in the flushing water reservoir container is suctioned, sprayed via the spray device into the toilet bowl, and suctioned into the vacuum wastewater line. | 12-10-2009 |
| 20090300835 | Air flush system - A system and apparatus for reducing the amount of water required for flushing toilets. The system flushes a toilet containing a small amount of water in the bowl with air forced into the bowl from a special airtight lid and a vent in either this lid or in the toilet bowl area. While holding down the airtight lid, injected air from an air pressure device connected to the vent flushes the toilet, using minimal water as compared with conventional toilets. Afterwards water is added to the toilet bowl to reseal the trap and ready the toilet for the next use. By allowing this same air pressure device to produce suction as well as air flush, it will also function as a dry plunger in the event of a blockage and because this system uses air rather then water for flushing the swear pipe is predominately filled with air preventing freezing of pipes. It also will give a long flush capacity for those systems that enter a cesspool or septic tank. | 12-10-2009 |
| 20100024116 | Non-water Lavatory Flushing Device with Flushing Pump - A non-water lavatory flushing device consists of a electrical four-way valve, which one of its exit is connected with the exit of the side wall of the valley at the back of the toilet pan for collecting the feces. The three exits are connected with the central part of the toilet pan, feces collecting box and the flushing liquid collecting box through a feces dispersing pipe, a feces collecting pipe and a urine collecting pipe. The non-water lavatory flushing device of the invention uses a four-way valve to replace the feces dispersing pipe magnetic valve, feces collecting pipe magnetic valve and urine collecting pipe of the prior art. The dispersed feces liquid and urine in the feces dispersing pipe, feces collecting pipe and urine collecting pipe is controlled by the four-way valve respectively. Then the structure is simplified and the cost is decreased. Furthermore, as the four-way joint is cancelled, the problem of wrong flowing of the leaving liquid is solved. Thus, it could be avoided that the feces plasm flow into flushing liquid collecting box or the limited clean urine is discharged along the feces collecting pipe and this is advantaged to improve the flushing effect. | 02-04-2010 |
