Abstract: The discharge valve has a valve housing (14) which has an outlet opening with a valve seat (16) and also a closure body (12). A two-quantity actuator (4) has a connecting rod (10) which is connected to the closure body (12) and by means of which the closure body (12) can optionally be raised by different displacement distances.

Abstract: The adjustable flapper comprises at least an adjustable flapper comprising at least a base to which is adjustably engaged a seal assembly including a seal, the seal depending from the base, and the seal assembly being movable in at least one desired direction relative to the base to accommodate any required distancing of the seal from a free end of the base and the seal being adjustable in angulation relative to the base.

Abstract: A gutter cleaner comprises a float portion and a stem portion. The float portion comprises a float piece that typically has a size larger than the downspout opening of a gutter in which the gutter cleaner is installed. Accordingly, the float will not flow down or become lodged in the downspout. The float piece is made of materials or in a manner such that the float piece will be raised within the gutter when water flows there through. The stem portion typically is attached to the float portion and extends downwardly into the downspout of the gutter. As rainwater flows into the gutter and down the downspout, the water will raise the float while the stem portion will remain extending downwardly into the downspout. The flow of the water agitates the stem and the float regions of the gutter cleaner. This agitation action reduces the buildup of small twigs and pine needles at the downspout region, thereby facilitating the flow of debris and water down the downspout and out of the gutter.

Abstract: A water saving apparatus for water tank includes a stop valve means located above a water outlet, a linkage bar means located above the stop valve means and two chains for connecting the stop valve means with the linkage bar means. The stop valve means has a valve cap engaged with a movable strut and a hollow ball for linking to a tank ball. The linkage bar means has a handle located outside the water tank. The handle engages with a shaft stem and a shaft sleeve for actuating two beams located inside the tank. The chains connect the beams respectively with the tank ball, hollow ball and movable strut. Moving the handle downward, one beam will be moved up to make the hollow ball become buoyant for opening the water outlet rapidly to release a large amount of water to flush feces. Moving the handle upward, another beam will be moved up to make the hollow ball become not buoyant for closing the water outlet sooner so that a small amount of water will be released for flushing urine for saving water.

Abstract: The Two-Level Flush Valve retrofits into standard toilet tanks replacing the flush valve and pull cord. Depressing the toilet handle through the usual first resistance lifts a non-buoyant valve (20) open. It is held open by an upper float (28) fastened onto a pull cord (24). When water lowers to the level of upper float (28) the float drops, allowing the valve to close. This accomplishes a short-duration flush that clears liquid waste from the toilet bowl and saves about a half tank of water. Depressing the handle through a second resistance causes valve (20) to pull a carriage (32) up and out of a latch (52). Lower floats (40) on carriage (32) hold valve (20) open until the tank is almost empty. This accomplishes a full flush that ensures that solid waste is flushed out without leaving dirty water in the toilet bowl. A valve delayer (62) holds valve (20) slightly open for a few seconds to allow complete refilling of the toilet bowl.

Abstract: A gravity flush toilet system includes a fixture with a water sealed trap and a tank having an overflow tube, a flush valve and a fill valve. A control assembly includes a float assembly with a member for pushing the flush valve toward its closed position as the water level descends. A full volume or a reduced volume flushing operation is selected by alternatively filling or emptying a bias chamber of the float assembly. Water pressure variations are compensated for by increasing the weight of the float with part of the flow through the fill valve as the tank is emptying. A regulated volume of reseal water is carried in a chamber on the float and is discharged into the overflow tube to refill the fixture trap after each flushing operation.

Abstract: Apparatus operative to selectively discharge substantially all or only a predetermined portion of the water within the flush tank of a toilet. The apparatus includes an open ended float having selectively regulatable venting ports for controlling float weight and buoyancy by the water-air ratio therein. The float is constructed in a size adaptable to most existing commode flush tanks and is assembled therein by attachment directly to the flush valve thereof. The float water-air ratio is then set into the desired flush mode by selective venting of the ports whereby an unweighted float will permit a full flush and a water filled float will drive the flush valve into a premature closure for discharging only a portion of the water within the flush tank.
