Abstract: Systems, devices, and methods for a one-time disposable device arrangement for dispersing liquids of varying viscosities, or their constituents, in a metered manner over a definable period of time. The invention employs a flexible reservoir, of varying size, shape, and configuration, along with a calculated, finite length of looped flexible tubing, one of varying size, shape and configuration. The device arrangement can be hung over an area where it is desired to attract animals such as deer by dispensing liquids, such as but not limited to animal attractants, such as deer urine and buck jam, and the like.

Abstract: A ball check valve controls the flow of fluid with a sphere. A body has a fluid path and a recess for receiving the sphere in alignment with the fluid path. The sphere has a retainer which secures a ball check within it. When the valve is in a “Run” position and the rate of fluid flow increases, the ball check seats in a narrow opening of the sphere, thus blocking the flow of fluid.

Abstract: A portable hydroelectric generator that carries its own water supply. A tube with a first opening at one end for receiving fluid from a trough and a second opening at the other end for discharging the received fluid. The tube has an inverted U shape having a side A which extends from the first opening toward the top of the inverted U and a side B which includes a turbine coupled to a generator extends from the top of the inverted U to the second end. Side A has a volume which is smaller than the volume of side B and the second opening is located above the level of the fluid in the trough. When fluid is in the tube, its weight in side B is greater than its weight in side A which causes the fluid to flow from the first opening through the tube and out of the second opening.

Abstract: A device for reusing greywater includes: a water feed for supplying greywater; a collecting reservoir for collecting the supplied greywater; a storage tank for storing water; a siphoning device for siphoning water from the collecting reservoir to the storage tank; a water discharge for discharging stored water to a water user; a sewer outlet; and a control system. A method of siphoning water includes: supplying water to a collecting reservoir; detecting a predetermined water level in the collecting reservoir; operating a filling valve subject to the detected water level; and siphoning water via a siphon connection from the collecting reservoir to the storage tank.

Abstract: A self-priming siphon has an inverted U-shaped tube filled with a hydrophilic material where one end of the tube is connected to a smaller diameter tube such that when the other end of the tube is immersed in a liquid, capillary action causes the fluid to rise in the tube above the level of the water and thereafter fall through said one tube end causing a suction which primes the siphon.

Abstract: A siphoning device used to attain the desired level of water in a swimming pool or other like pools of water that are either overfilled from rain water or from overfilling. A small simple plastic tubular device that is designed to connect to a regular garden hose and hang over the pool edge. A vertical soft plastic threaded tubular pick-up pipe exhibiting threads on one end connects into a vertically aimed threaded fitting of the device and extends into the water to be cut-off by user with a knife at the point that represents the users desired level of water for the pool. Upon filling of the garden hose with water and creating a natural gravity siphon action by locating the termination portion of the hose at a point in the yard that is horizontally a few inches or more lower than the desired pool level, water will be pulled or drained through the siphon device until pool water level reaches the level of the soft plastic pipe cut-off.

Abstract: The discharge conduit by which clarified sewage is withdrawn from a sewage clarification plant comprises a headwater conduit section and a low-water conduit section, the latter being separated from the former. The two conduit sections are connected to each other by at least one overground tube, the tube being designed as a siphon. An UV irradiation apparatus is provided for disinfecting the clarified sewage. However, the UV irradiation apparatus is not arranged in the discharge conduit, but is built in into the siphon. This solution has the advantage that the UV irradiation apparatus, which is installed overground, is less susceptible to failure and can more easily be serviced.

Abstract: A siphon head for siphoning smooth or rough textured roof surfaces which is preferably comprised of a soft pliable elastomeric material such as rubber. The head includes a relatively flat foot flange adapted to rest flatwise on a roof to be drained. The flange is of an annular shape. A dome shaped head portion is centrally located and integrally formed with the relatively flat foot flange. The relatively flat foot flange extends outwardly in a relatively flat plane beyond the head portion and surrounds the head portion in all directions. The head portion is closed on its top side and has an interior cavity. An opening is located on an underside of the head portion in communication with the cavity for receiving fluids to be siphoned. A discharge nozzle is positioned in fluid receiving communication with the interior cavity and extends radially away from the head portion atop the foot flange.

Abstract: Siphon assembly for a flushing cistern is in two parts; the first including the down leg of the siphon duct the lower end of which is mounted in the cistern base and the second including the up leg and the inlet chamber in which the flushing piston is received. The parts are releasably connected by a push fit spigot and socket joint secured by a removable pin received transversely through locating formations on each part near the tops of the legs, further formations near the bottoms of the legs being received in vertical sliding relationship.

Abstract: A hydraulic memory device has two elongated passages for liquid, an input member connected with upper ends of the elongated passages for liquid supply into the latter, and two output members each connected with a lower end of the respective passage, wherein the output members are formed so that a portion of liquid supplied in a preceding step remains in one curved output member, and during a subsequent step of liquid supply the liquid will flow into an elongated passage provided with the other output member.

Abstract: The invention provides a siphonic apparatus to effect irrigation of a field from a water supply. The apparatus comprises a bridging structure which includes a chassis fabricated from spaced longitudinal bottom members, spaced longitudinal top members interconnected by cross members, vertical struts, diagonal braces and side plates to form a rigid structure having a central elevated section and downwardly angled end sections, the ends of which being on substantially the same plane as the surface supporting the chassis.At least one siphonic tube is rotatably, transversely supported in the chassis.

Abstract: An assembly for conveying and discharging corrosive fluids comprising a substantially closed receptacle and a substantially tubular non-metallic corrosion-resistant siphon extending into the receptacle from the outside of the receptacle are disclosed. The siphon tube generally comprises an inner layer of corrosion-resistant resin, a structural layer of unidirectional glass fiber disposed around the inner resin layer, and an outer layer of corrosion resistant resin disposed around the structural layer of unidirectional glass fiber. Methods of making the siphon and using it in its intended environment are also disclosed.

Abstract: A valve for use in an apparatus for supplying molten metal by means of a siphon to a furnace. A valve formed by a tube provided with two flanges is placed at the upper part of the siphon, this tube extending by a certain length below the level of the flanges, so as to form an annular space with each of the branches of the siphon in which the gas is trapped during decanting, which prevents the gaskets from being in contact with the molten metal.
