Abstract: An apparatus for automatically shutting off a water supply to a leaking water heater includes a water-collecting tray adapted to be positioned beneath a water heater, and a float mechanism removably attachable to the tray. The float mechanism has a float adapted to reside within the tray. An arm extends from the float, and terminates in a trigger extremity located outside the tray. The trigger extremity is positioned to push upwardly upon a holding block that secures an extremity of a coil spring. The holding block also secures a tether that extends to an operating lever of a water shut-off valve. When the float rises in the tank, it causes the trigger extremity to release the coil spring in tensioned state from the holding block. Such action pulls the operating lever downwardly, causing shut-off of the water supply.

Abstract: This invention relates to an improved valve which achieves high reliability through a simplicity of design, a minimum number of parts, a unique valve seat with a two stage sealing action, and at the same time provides a large flow when in the open position, owing to a large cross section opening. The valve features an improved sealing efficiency, in that when in the closed position an increase in pressure on the valve improves the performance of the valve, rather than increasing the likelihood of a leak. The valve is designed to be used in applications which permit the flow of material beyond the valve mechanism to discharge freely, whereby the discharged material activates a float mechanism so as to permit the valve to close when the discharged material reaches a preset level.

Abstract: A cylindrical perforated member is mounted between a working fluid inlet port and a hermetic vessel that a working fluid supplied into the hermetic vessel at the working fluid inlet port will not directly contact the forced-feed liquid surface. At the working fluid inlet port is mounted a ring-shaped member with a divergent section having the smallest flow passage area. The working fluid stream is deflected and dispersed by the cylindrical perforated member, to produce a pressure for feeding the liquid rapidly within the hermetic vessel, thus enabling the rapid forced-feed of the liquid.

Abstract: A system for providing a liquid to a plant or tree stand comprising a liquid reservoir connected via tubing to a liquid control assembly having a liquid level control section positioned on the lower end of an adjustable vertical section with straps for attachment to a tree. The liquid level control section comprises a lever arm/float assembly positioned within the tree stand for maintaining a predetermined liquid level within the tree stand. As the liquid in the tree stand is depleted the float drops and the opposite end of a float lever arm penetrates a channel raising a metal ball which permits liquid to enter the tree stand through the liquid level control assembly connected to the tubing from the reservoir. As the liquid rises in the tree stand, the float is forced upward causing the opposite end of the float lever to drop resulting in the metal ball lowering to seal the channel thereby stopping the liquid flow into the tree stand.

Abstract: A device, and a container having such a device, is provided for permitting filling the container with a predetermined weight of the fluid. The device and container include a main channel to introduce the fluid into the container at a fill pressure; a detector mechanism to detect a "filled" condition based on fluid weight; and a fluid-weight control mechanism to automatically prevent introducing fluid into the container in excess of the "filled" condition. A spring offsets part of the weight of a pivotally mounted displacer mounted on a pivotally mounted lever having an arm configured to permit closure of a ball valve as the container becomes "filled" and the displacer becomes buoyant. The fluid-weight control device, which is substantially independent of the composition and temperature of the fluid and of inertial effects induced in an attempt to thwart the fluid-weight control safeguard, also prevents introduction of fluid into the container as the container is non-upright.

Abstract: A toilet having a water inlet valve apparatus has a flush tank with a water inlet tube connecting from a water source into the flush tank. A water cutoff is attached to the water inlet tube and has a valve seat in a floating valve element positioned in the water inlet tube to seat in the valve seat responsive to water in the water inlet tube so that the water is cut off from entering the toilet tank when the valve element is seated in the valve seat. A removably attached ballcock valve assembly is removably attached to the water cutoff valve and water inlet tube and has a valve opening member positioned to hold the floating valve element in the water cutoff valve from the valve seat when the ballcock valve is attached to the water cutoff valve. Removing the ballcock valve from the water cutoff valve closes the water cutoff valve and stops the flow of water into the tank from the water inlet tube.

Abstract: A water level control device has connected tubular housings, one serving as a support for a hose connection and the other serving to house a float assembly for operation of a ball valve within the valve housing. An airtight float serves to raise the one extreme of a lever arm when buoyed by sufficient water level admitted through apertures in the float housing. The other extreme of the lever arm includes an upward projection that contacts a ball within the ball valve cavity urged against a lower valve seat by water pressure from a water hose. When the water level in the pool, and thus the float, is lowered, the one lever arm extreme will also be lowered raising the other extreme to cause the projection to lift the ball away from the valve seat and permit water from the hose to enter the pool. A water flooded ballast attached to the float provides a dampening effect so that the ballast and apertured float housing serve to dampen float motion due to surface waves.
