20110219528 | Cartridge Unit and Trap for Sewer Gas & Odor Containment - A cartridge unit for use with a urinal is disclosed that does not need water to work nor does it use a body of oily liquid sealant as an odor barrier. The odor trap cartridge unit used in this urinal has a spring locking mechanism that works as a valve. It is opened by liquid weight when the urinal is used and lets urine or any other liquid pass downwardly through it and prevents odors from flowing back up towards the room. The cartridge unit has a few disks, two main cylindrical devices, a spring, a fastener, an o-ring, and a coupling; these all operate to open and close a spring sealed trap. These are all placed within a unique three-sized shell that supports the entire cartridge and is fitted into a urinal opening. An umbrella shaped part completes the cartridge by protecting its components from violent fluid flow. | 09-15-2011 |

The fixture drain insert assembly can be retrofit into existing fixtures such as urinals to create efficient and clean low water to no-water use fixtures or be integrated into new fixtures with corresponding mating features to optimize fit. | 09-18-2014 |
20140259349 | Water Conservation Fixture System and Method of Use - A water conservation fixture system comprises a handle lock assembly configured for placement on a handle of a fixture and at least one other structure selected from a fixture drain insert trap assembly, a fixture screen and combinations of both. The handle lock assembly comprises a top component and at least one locking arm pivotally attached to the top component, and the locking arm further comprising a locking element for releasably locking with a mating locking element on the top component. The fixture system may be integrated into existing fixture to significantly reduce or control water usage or otherwise convert the fixture to a low-water or no-water fixture without having to replace the current water-based fixture. The fixture system may also be integrated into new fixtures with corresponding mating features to optimize fit and function of the system with the new fixture. | 09-18-2014 |

20100031430 | FLUSH APPARATUS AND FLUSH CONTROL METHOD THEREOF - The present invention provides a flush apparatus and a flush control method thereof. The flush control method includes the steps of detecting a target, counting an interval time from a previous flush to the detection of the target, and comparing the interval time with at least one pre-set interval time to determine an operating mode of the flush apparatus. | 02-11-2010 |
20100180367 | METHOD AND ELECTRONIC CONTROL APPARATUS FOR CONTACTLESSLY CONTROLLING A SANITARY FACILITY - In the method for contactlessly controlling a sanitary facility, a transmitter, a receiver, an evaluation unit and a control unit are used to monitor an area ( | 07-22-2010 |
004303000 | Periodic flush | 1 |
20140304902 | Periodic Heavy Flush Valve Control Device, Method and System - The smaller volumes of water currently required to flush toilets and urinals may be insufficient to clear the fixtures and the drainage lines to which they are connected of waste and other undesirable materials, which can build up over a period of flushes or non-use. A flush valve control device programmed or otherwise configured to provide a selectable, periodic heavier flush volume of water after a predetermined number of low volume flushes and/or after a predetermined period of inactivity of the toilet or urinal can provide for sufficient drainage line carry-out of waste and prevent undesirable buildup of minerals, etc. on the inside surfaces of the fixtures and drainage pipes. | 10-16-2014 |
