  • Patent number: 9896248
    Abstract: A dispensing bottle has a spout formed integrally with a neck that extends to a body of the bottle. The spout comprises first and second passages oriented at an angle to the neck. A partition inside the neck forms an extension of the second passage. The partition extends at least to a base of the neck such that air entering the second passage is carried through the neck and released into the body of the bottle. The bottle may have first and second parts detachably affixed together.

  • Publication number: 20150136241
    Abstract: A liquid storage and delivery system includes a reservoir and a storage container. The storage container has a main body with a hollow interior, and is configured to hold a reserve volume of the water. The main body has an upper wall and a lower wall. The hollow interior is disposed between the upper wall and the lower wall. A refill conduit is in communication with the hollow interior of the storage container. An air conduit is in communication with the hollow interior of the storage container and the reservoir. A liquid passage is in communication with the hollow interior of the storage container and the reservoir. The liquid passage is configured to deliver the water from the storage container to the reservoir. The liquid storage and delivery system is particularly useful for the watering of plants and animals.

  • Patent number: 7165950
    Abstract: A two-stage pressure relief valve for use with hydraulic systems is disclosed. The two-stage pressure relief valve has a first stage that relieves increases in hydraulic system pressure over the normal operating pressure and up to a selected threshold pressure level, and a second stage that brings the hydraulic system pressure down to a selected reduced operating pressure that is below the normal operating pressure in response to increases in the operating pressure over the threshold pressure level.

  • Patent number: 5358000
    Abstract: A siphon pump system for pumping water from a water source to a supply destination. The system includes a holding canister through which the water flows, and a first timing bucket associated with the holding canister for controlling the admission of air into the system to thereby permit flow of water contained within the holding canister. A lower flow control chamber is provided adjacent the outlet from a long, second siphon conduit extending from the holding canister to control the refilling of the holding canister in an automatic manner and without the need for connections with a source of electrical power.

  • Patent number: 5339858
    Abstract: The invention provides a device for restoring a fluid level in a fluid receptacle to a predetermined level when the fluid level falls below the predetermined level, said device including: a closed vessel for containing a fluid supply, the vessel having an aperture allowing the fluid supply to be in communication with fluid in the fluid receptacle, and an air inlet tube extending into the vessel; wherein, in use, the inlet tube is positioned such that air is drawn into the vessel when the level in the fluid receptacle falls below the predetermined level thereby allowing fluid to pass through the aperture into the fluid receptacle until the fluid level is restored.

  • Patent number: 4911891
    Abstract: An apparatus and method for on-line monitoring of a characteristic of a process liquid stream includes a cell for isolating a precise volume of the liquid. There are provided means for over-filling a sample chamber and means for removing the excess from the chamber comprising a downwardly extending drain line which terminates at a precisely positioned, downwardly facing inlet and means for applying negative pressure to the drain line to draw the excess liquid upwardly from the captured volume until the liquid level reaches the inlet and entry of air disrupts the liquid draining effect. The embodiment shown employs a closed volume, a vent, a conduit for delivery of process liquid into the cell under pressure and a syphon/drain line for removing excess liquid from the cell volume until there remains only a sample of accurately repeatable volume.
