Abstract: The separating valve is intended for discharging the liquid phase of a two-phase fluid. It comprises a seating and a valve member, the latter being actuated to open by a float at the end of a first arm of a lever, whose other arm comprises a cam which engages in a neck of the shank of the valve member. The seating comprises a port at the center of a flat face from which projects a sleeve for guiding the shank of the valve member. Directed towards the flat face, the valve member comprises a flat plate from which there projects a truncated conical valve needle. Between seating and valve member there is defined an annular space communicating by three passageways with the chamber for receiving the liquid phase: one passageway which is an extension of a slot where the lever arm fits, and two passageways along a diameter perpendicular to the slot and tangential to the flat face.

Abstract: A fill valve assembly installed in a toilet flush tank includes a pressure relief valve adapted to activate at a predetermined pressure to discharge water from a system of piping to relieve pressure due to thermal expansion of water in the piping system.

Abstract: Apparatus for regulating the flow of a subject fluid which includes immiscible fluids having differing densities such as oil and water, wherein plug means are provided which sink in oil and float in water, said plug means being positioned to control the flow of fluids through a scupper aperture. The plug means cause a sealing surface to move in and out of contact with the scupper aperture. Means are provided to enhance the separation of the sealing surface from the scupper aperture when fluid flow is to be permitted, and to increase the fluid tightness of the seal when fluid flow is to be prevented. Means are also provided for reducing the effects of turbulence in the subject flow, and hence to enhance the separation of the immiscible fluids from one another.

Abstract: For detecting small level changes in an aquarium, there is proposed a sensor which, in the operable condition, comprises a substantially enclosed sensor container (18), into which aquarium water can be sucked from the surface via an overflow edge (56) and from the aquarium interior via a suction port (46) with a downstream overflow tube (52). The sucking of the water over these two paths is effected by a circulating pump (26) of the aquarium filter system via an outlet port (32) of the sensor container (18). The liquid level in the sensor container is monitored by a level sensor (64). The upper edge of the overflow tube (52) is located beneath the overflow edge of the container wall by a specified distance. If water losses from the aquarium arise, the water surface in the sensor container drops to a considerably greater extent than the water surface in the aquarium external chamber does.

Abstract: A flushing cistern includes a flushing device which is located in a liquid-containing cistern. The device includes a hollow tube and a closure member carried by the tube. The tube can be moved in the cistern between open and closed positions in which the closure member is clear of, and seals the cistern outlet. A float is mounted on the tube to hold the tube in the open position while flushing takes place and which causes the tube to resume its closed position at the end of the flush. The device also includes a float arm carrying a float. The float arm is pivoted to a control arm of the inlet valve to the cistern, and there is a detent on the tube which engages the float arm and pulls it downwardly when the flush is over, so operating the control arm and opening the inlet valve to admit further liquid to the cistern. When the cistern has again filled up, the float arm detaches itself from the detent, and permits the inlet valve to close again.

Abstract: There is described a snorkel mast for a submersible vehicle. The mast terminates at the upper end in an inverted U-shaped snorkel head pipe section closed by a butterfly valve. The butterfly valve is operated by a bell-crank lever having a float at one end and a water impact flap at the other. Operation of the bell-crank lever by water level action against the float or by water impact action on the flap if a wave washes over the top of the snorkel mast acts to close the butterfly valve. The mast carries a fairing which comprises a number of fairing elements of airfoil cross-section, vertically spaced on the mast so as to be freely rotatable thereon in water lubricated bearings. The segmented fairings on the snorkel mast maintains hydrodynamic stability during high speed turns.

Abstract: Hose connector adapter apparatus for an evaporative cooler float valve includes an integral ferrule for sealing the float valve to the adapter and an internal hexagonally configured passageway through which the water flows and which passageway receives a hex wrench or the like for securing the adapter to the float valve when there is insufficient external clearance for manually securing the adapter to the float valve. The adapter apparatus is able to be secured to evaporative cooler float in virtually any location on a cooler housing, regardless of the cooler housing configuration either by manually securing the adapter or by using a wrench internally.

Abstract: In a discharge regulator for outlets from liquid containers, in particular rain runoff retention reservoirs, in which a regulator plate or diaphragm is guided in front of the outlet opening and is operatively connected to a float by means of transmission elements which may at the same time be control elements, the regulator (1) is guided pivotally in front of the outlet opening (2) and is mounted above the latter on a fixed rotation axis (4) jointly with a disk (3) on a base plate (11). A transmission element (5) or (12) connects the disk (3) to a second upper rotation axis (7) on which a disk (6) is operatively connected to a float arm (8) and then via the latter to the float (9) (FIG. 1). The float (9) and float arm (8) as well as the plate (1) can optionally be arranged on alternate sides. Apart from these components all the other drive and transmission elements may be protected by a hood.

Abstract: A water level control device is adapted to be detachably mounted within a swimming pool at the desired water level. A float controlled valve is mounted within the housing which is responsive to changes in the water level of the swimming pool and which is provided with a water inlet and outlet located outside of the housing so as to prevent turbulence within the housing. A suitable air vent is provided adjacent the top of the housing above the water line and restricted water inlet apertures are provided adjacent the bottom of the housing below the water level to maintain the water level within the housing at the same level as the water level in the pool.

Abstract: The overcharge prevention device is installed in a solvent processing plant in a vacuum evaporator of a heat exchanger. It assures that the level of the cleaning solution in the vacuum evaporator cannot randomly rise when a feed valve malfunctions. A float body of an overcharge valve extending into the vacuum evaporator exerts a pressure through a double-arm lever and a valve plunger upon a ball valve and a valve seat in normal operation and holds the overcharge valve in a closed position. As the level of the cleaning solution undesirably rises, the buoyant action of the cleaning solution acts on the float body, causing the pressure on the valve seat to diminish, and the overcharge valve opens. This permits air to enter into the vacuum evaporator through the overcharge valve. The generated vacuum collapses and the suction force employed to ingest the cleaning solution disappears.

Abstract: A deck ventilator suitable for small vessels is formed as a low dome 12. Outside air may enter it through window 14 and then circulate around member 30, through orifice 22 and down duct 7 which pierces deck 4. Member 30 usually serves merely as a shield against spray, however if a surge of water enters compartment 18 the orifice 22 is closed by movement of member 30 which is slidably hinged to U-shaped rods 23. This closing movement results from the combination of the impact of the water on member 30 and the member's inherent buoyancy.

Abstract: The condensation discharger comprises a tank (1) including a float (8) and an elastic cut-off blade (14) the blades of which being connected in such a way to the forked arm (6) of the float (8) that the discharge orifice is opened when the float is moved beyond a certain level.

Abstract: A rising liquid level in a gas scrubber for an air compressor is sensed by a float in the scrubber which opens a normally closed pneumatic vent valve whereby a very small pneumatic signal is delivered through a pneumatic spool valve to the chamber of a large diaphragm liquid dump valve on the scrubber which is operated automatically to drain liquid from the scrubber to maintain a safe liquid level in the scrubber. The dump valve mounted on the scrubber side wall penetrates deeply into the scrubber to avoid freezing of the dump valve.

Abstract: A horizontal water inlet tube is inwardly connected reversely through a valve within a horizontal valve housing and from the valve housing downwardly into a generally vertical water outlet tube. The valve is controlled by a valve control arm projecting generally horizontally from the valve housing downwardly connected through a float connector to a float vertically slideable on a float guide extending downwardly from the valve housing. A diverter at the upper end of the water outlet tube receives water flow generally horizontally from the valve housing into a pair of spaced, downward helical grooves directing the flow spirally into a pair of spaced vertical grooves for ultimate discharge downwardly through the water outlet tube. The diverter vertical grooves are larger in cross-section than the respective helical grooves and are formed by radial plates converging centrally to a cylinder at groove upper portions and an inverted cone at groove lower portions, each vertical groove occupying in the order of 120.

Abstract: A float chamber is defined within a body, which is also formed with an inlet passage for supplying fluid into the float chamber, and an outlet passage for taking fluid out from the float chamber opening into a lower part of the float chamber. A float is mounted within the float chamber so as to be movable up and down, and acts on a fluid valve for controlling fluid flow into the float chamber through the intake passage, causing the valve to open and close. The shapes of the float and the float chamber are such that the amount of fluid required to be present in the float chamber in order to float the float at the position in which it just causes the valve to be closed, in equilibrium between its weight and the buoyancy force exerted by the fluid, is independent of the angle of tilting of the float chamber within a certain tilting range.

Abstract: A valve, of compact design, permits the opening and blocking of a liquid flow whose level is directly proportional to the operation of the valve, with the use of conventional floats being completely abandoned, and with the hydraulic mechanism of said valve being activated in different manners, according to the origin of the source of flow, which can be produced either through the upper part of the tank or from the bottom. There are three embodiments of the valve.

Abstract: A float controlled valve syphons water out of a swimming pool cover. The syphon valve includes co-operable male and female valve members disposed for mutually relative movement to bring them into and out of mutual engagement to thereby close and open flow communication through a syphon discharge passage formed in the male member. A float body is coupled to one of the said members for effecting the engagement and disengagement in response to the level of the water in the swimming pool cover. The male valve member is tapered at the forward end to facilitate engagement with a central recess in the female member. The female member is formed of more yielding material than the male member and has a thin walled portion receiving the male member and of sufficient flexibility to envelop dirt particles at the male-female member seal.

Abstract: A toilet tank has water supply and overflow ducts which are integrally formed with the base and walls of the tank. The water supply duct is connected to a water inlet at one end to supply water to the tank and has an inlet valve at its other end to control the supply of water to the tank. The overflow duct is open at its top to receive overflow water in the tank and is coupled to the toilet basin to pour the overflow water into the toilet basin.

Abstract: Sequential, continuous delivery of separate intravenous fluid mixtures is facilitated by a float operated valve which automatically re-starts flow from a primary solution when the selected volume of secondary fluid has been infused. The float is contained in a calibrated volumetric chamber with a drug injection port, and valved connections to primary and secondary solutions. Selected volumes of primary or secondary solution can be added to the chamber and mixed with drugs inserted through the injection port.Fluid in the calibrated chamber raises a float which closes a valve and stops fluid flow from the primary solution source. Fluid from within the chamber flows to the patient until very little fluid remains in the chamber and the float moves downward causing the valve to the primary solution to open allowing a continuous flow of intravenous fluid to the patient.

Abstract: In a poultry watering system having a float-controlled valve for maintaining a desired water level in a trough, leakage through the valve from an overhead supply line, which may occur when the water supply is cut off is effectively prevented without reducing sensitivity of the float by the provision of spring means located within the interior of a valve housing and acting on the end of the float stem.

Abstract: An essentially closed hollow body of the float receives liquid in a lower portion for ballast and air in an upper portion for floatation with a vertical guide sleeve therethrough being offset at one side of the hollow interior slightly spaced inwardly of a part of the body sidewall. A liquid and air flow opening is formed through the body sidewall part horizontally centered relative to the guide sleeve so that flow paths are created segregated approximately one half around either side of the guide sleeve. By arcuately forming the body interior and the guide sleeve, not only are the flow paths smoothly arcuate, but the circuitous nature thereof muffles echoing sounds created within the hollow body from passing outwardly of the body through the flow opening.

Abstract: A T-shaped pipe whose base extends through a sidewall of a steam trap housing terminates internally of the housing in open ended upper and lower vertical arms.
