Abstract: An improved water-saving toilet flapper valve (20) that calls for an end to automatic toilet flushing; instead it is operated manually. By manually depressing the toilet flush handle (72) for a desired amount of time, the user regulates the amount of water flushed down the toilet in a single session, thus saving water. A short flush interval or full flush interval can be achieved. This is accomplished by designing the flange body (50) of the toilet flapper valve to house a solid inner core (54) containing a weighted mass (56). This allows the toilet flapper valve to become non-buoyant when submerged underwater in a toilet tank (60). The flange body design is an improvement on prior-art since it acts as a flange to create a positive seal with the valve seat (68) of the toilet tank; thus preventing water leakage. This improved toilet flapper valve design can replace a standard toilet flapper valve without the need of additional tools or costly modifications.

Abstract: Jewelry can include a stone and a setting. The setting can include rings, wherein at least one of the rings contacts the stone. The rings may be in the form of chains, netting, or both. The rings can be attached to the stone using anchor(s), so that the setting cannot be removed from stone unless the stone, a ring, an anchor or combination thereof is broken or, in the case of hooks, removed only with great difficulty or irreversibly damaging the hooks (e.g., when separating ring and hook combinations). The configurations for the settings and stones and methods described herein can substantially increase the options for designing jewelry, and particularly the use and arrangement of stones in jewelry.
