Abstract: The present invention relates to an automatic valve actuating system that is responsive to various externally detected stimuli. The system is comprised of a monitoring and alarm components that close a valve upon the detection of a fault occurring from the undesirable presence of carbon monoxide or combustible gases.

Abstract: A clothes washing machine includes a water drain having a motor-actuated valve. The motor drives first and second rotatable members in a common first direction until the second rotatable member reaches a drain-opening position for actuating a drain-opening mechanism to open the drain valve. Simultaneously, an electric switch is operated to temporarily de-energize the motor in order to keep the valve open for a predetermined period. After the motor restarts (i.e., once the draining has been completed) the first and second motors are again rotated in the common first direction until a cam on the second rotatable member engages a fixed cam. The cam on the second rotatable member rides on the fixed cam to disengage the second movable member for rotation relative to the first rotatable member in a second direction to reclose the drain valve.

Abstract: A water saving device, implemented as a pair of spring loaded, normally-open shutoff valves inserted into the hot and cold water supply lines of a faucet, which are connected via a cable mechanism to a foot actuator. Actuating the mechanism causes the shutoff valves to close, interrupting any flow of water in the supply lines. Releasing the mechanism allows flow to resume. The shutoff valves are installed in series upstream of the normal hand-operated faucet valves. The user starts the water flow and adjusts the temperature of the water in the normal manner using the hand-operated faucet valves. When the user wishes to temporarily stop the water flow he or she steps on the foot pedal, thereby causing the shutoff valves to close. When the pedal is released the shutoff valves open and the water flow resumes at the same flow rate and temperature previously set by the user.

Abstract: An improved toilet flapper valve (10) designed to directly replace either a conventional toilet flapper valve or tank ball valve. The valve (10) allows a toilet user to selectively determine the quantity of water used for a toilet flush by controlling the time that a toilet flush handle (38) is held in the depressed position. The water quantity used depends on whether liquid or solid waste is to be flushed. For liquid waste, a partial flush is used; for solid waste a full flush is recommended. The valve (10) consists of a resilient body having a cavity (12) located over the toilet tank drain (34). The cavity houses a weight (16) that fulfills two functions: it provides the weight necessary to make the valve non-buoyant and it produces under the area of the weight, a flat rigid section (18) that extends radially over and beyond the perimeter of the valve seat (36). This rigid section provides a positive seal without sagging which can produce unnoticed leaks.
