  • Patent number: 8443828
    Abstract: A device allows a liquid to flow between two open structures with different liquid surface elevations separated by a wall. The device has a conduit with an inlet on one side of the wall and an outlet on the other side of the wall separated by a high point above the expected liquid surface elevation. The conduit also has two valved openings, one connected to a source of suction that can evacuate air from the conduit and the other connected to a vent. In one example, the conduit is formed between a pair of spaced transverse walls attached to an arched cover. The transverse walls each have a slot allowing the device to be placed on top of a dividing wall between two tanks with surfaces of the dividing wall defining part of the conduit. In an example with multiple conduits, one or more interior walls are provided between a pair of end walls and a cover over the interior and end walls may be provided in segments. To initiate flow, a conduit is evacuated of sufficient air to allow a siphon to develop.

A siphon line is connected to the pick-up at one end and terminates in the first section at another end. A fuel inlet of the pickup communicates with the siphon line through a valve member that is actuated to open and closed positions. In operation, the fuel pump provides a flow of liquid fuel to the pick-up to purge and prime the siphon line which normally maintains a substantially equal liquid fuel level in the first and second sections of the fuel tank. In some conditions, the valve closes to prevent reverse flow of fuel from the first section to the second section of the tank.

  • Patent number: 5063959
    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.

  • Patent number: 5035535
    Abstract: A device for regulating the flow in a drainage siphon tube, includes a rigid tube connected to the outlet end of the siphon tube. The rigid tube is placed on a brace such that it can oscillate around a horizontal axis by means of a counter-weight. Pivoting upward of the tube is limited by a high block stop and pivoting downward is limited by a low block stop in such a way that when the siphon tube is delivering above its critical point, the tube is tilted downward, resting on the lower block stop and when the critical outflow is reached, the tube empties itself and comes to rest against the higher block stop by means of the counterweight. An increase in the pressure at the inflow end of the siphon tube results in a rise of the water in the rigid tube until the imbalance makes it pivot to the downward tilted position where it rests on the low block stop and delivery higher than the critical point ejects the gas bubbles accumulated at the high point of the siphon tube.

  • Patent number: 5009261
    Abstract: Disclosed is a heat accumulation tank system intended for use as a heat source of, for example, an air conditioner and which is installed, for example, in a building or under a green zone, a stadium or a parking area. The heat accumulation tank system is composed of a plurarity of water tanks which are connected through a communication passage such as a communication pipe. The pressure in the communication passage is controlled by means of a pressurizing device or a vacuum device, so that the state of communication is controlled such as to establish or interrupt the communication between the water tanks or to control the rate of flow of water between these water tanks.

  • Patent number: 4911211
    Abstract: An apparatus and method for changing the antifreeze in a vehicle requires only a garden hose and opening of the radiator cap. Water from the hose is utilized to prime a conduit for siphoning used coolant from a side tank radiator and for refilling the radiator. By operating the vehicle with fresh water in the radiator, coolant remaining in the system is mixed with the water, and repeated drainings decrease the remaining used antifreeze by about one-half each time. After removal of the desired amount of antifreeze, new antifreeze may be placed in the radiator.

  • Patent number: 4717284
    Abstract: A device is provided for draining ground in depth. Each drain includes a tube having perforations in its middle part (1) with solid walls and closed at its lower part so as to form a cup (2), and with solid walls and open at its upper part (4). A siphoning tube (6) is permanently immersed by its lower part (3) in the cup (2), rises inside the tube (1) and leaves through a side duct (5) to drop down again towards an outlet (8). The outlet (8) is at the same level as the upper edge of the cup (2) so that the end (3) of the pipe (6) is always immersed and so that the siphon cannot be unprimed even during a dry period and requires no intervention.

  • Patent number: 4703771
    Abstract: A vehicle fuel tank in which the tank bottom has a protrusion so as to provide a space for accommodating the frame and other parts of the vehicle under the fuel tank, the protrusion defining a plurality of compartments in the fuel tank. An overhanging siphon having an opening in the top thereof provides communication between compartments. A fuel inlet pipe and a fuel suction pipe are communicated with a first compartment so that the supply of fuel into the fuel tank and the suction of fuel from the fuel tank are conducted through the first compartment. A valve such as a float valve is provided on the siphon opening.

  • Patent number: 4651767
    Abstract: A conveyor belt dewatering system in which a siphon tube or pipe is vertically moveable on a tubular support whereby selectively its inlet is lowered into a conveyor belt. Counterweights counter the weight of the siphon tube, these weights being positioned in the tubular support. A source of service water is turned on by a float switch sensing water is the conveyor belt, the service water being used to submerge the weights and lessen their effect and at the same time be supplied to the siphon tube to increase its weight, whereby a siphon tube is lowered into the conveyor belt and siphoning from it commenced.

  • Patent number: 4611622
    Abstract: For use with a hydrocarbon-fueled furnace whose secondary heat exchanger so cools the combusted gas as to condense much of its water vapor, and having a blower to the flue, a combined trap and drain is provided for the condensate formed both in the heat exchanger and in the flue. At the base of the flue is a standpipe whose upper overflow outlet is connected to a dip tube. Between the level of its lower end and the overflow level is a side inlet into the standpipe, connected to a tube leading downward from the heat exchanger's condenser. When the furnace blower applies both negative pressure to the condenser and positive pressure to the flue, the water levels in the trap and tube adjust to balance out these pressures.

  • Patent number: 4579139
    Abstract: The partial vacuum produced at the inlet passage of a vortex chamber is employed to move liquid from one compartment to another in order to maintain the level of liquid in at least one of the compartments within a predetermined level of the liquid in the other compartment. In one embodiment, the vortex unit or other suction means develops a partial vacuum at the maximum height of a siphon tube extending between the two chambers, the vacuum drawing fluid from both or at least one of the chambers to the top of the tube thus initiating siphoning. A sump pump having a negative pressure insufficient to lift the liquid to the maximum height of the siphon tube is employed to deliver liquid to a load and concurrently to the vortex unit to establish the required partial vacuum to initiate siphoning.
