  • Publication number: 20090100880
    Abstract: An additive dispenser includes a fluid-retaining chamber. A siphoning post extends upward from a lower surface of the fluid-retaining chamber and cooperates with a cap or other structure so as to form a siphon chamber. When water is added to the chamber and a liquid level rises above an inlet to the siphoning element, a siphoning effect draws fluid from the chamber. When the siphoning effect is interrupted, any unsiphoned fluid remaining in the chamber exits by permeation through one or more porous elements located in a base of the chamber.

  • Patent number: 6494778
    Abstract: The present invention provides for an aroma-dispersing unit in the HVAC system of an automobile. The aroma-dispersing unit includes a passageway and an aroma cartridge housed in an aroma cartridge housing. The passageway includes a first portion, a low-pressure zone and a second portion. The low-pressure zone defines an opening. The aroma cartridge is in communication with the low-pressure zone. The aroma cartridge also defines an opening at the top of the aroma cartridge. The opening of the low-pressure zone and the opening of the aroma cartridge are alignable such that air passing through the low-pressure zone can extract aroma from the aroma cartridge. The aroma mixed air enters the second portion of the passageway where it is dispersed into the interior of the automobile. The amount of aroma extracted from the aroma cartridge can be varied by adjusting the proximity of the opening of the aroma cartridge relative to the opening of the low-pressure zone.

    Abstract: A siphon adapter is disclosed. The siphon adapter is comprised of a pipe configured so that one end of the pipe fits inside of a container through the opening and is in very close proximity with the lowest portion of container. The other end of the pipe is outside the container and connected to a shut-off device. It is lower than the first end so that after liquid starts to flow out of the container through the pipe and the shut-off device, the pipe forms a siphon and the liquid continues to flow out of the container even after the level of the liquid is below the opening until substantially all of the liquid has flowed out of the container or the shut-off device is turned off.

  • Patent number: 6213334
    Abstract: A flexible, three-dimensional container is made by a prescribed vacuum-molding and heat sealing process. The container possesses a precise, defined geometry before and during use. The container is formed from first and second walls. The first wall has a planar area and a vacuum-molded cavity area drawn out of the plane of the planar area into a predefined three-dimensional geometry. A second wall overlies the first wall to close the cavity area and thereby forms an interior compartment. A thermal seal joins the two walls together. The seal is formed by heating the second wall and the first wall in the planar area, while assuring that the cavity area of the first wall is not subject to heating and possible deformation of its precise vacuum-molded geometry.

  • Patent number: 5364034
    Abstract: The low flow irrigation system can be used for batch or continuous time-dependent watering. It takes the form of a reservoir tank with a screen basket which filters out large particles from the water coming into the system. A float valve shuts off and turns on the intake water to preserve a predetermined level of water. Once the tank is filled initially, a siphon is started to begin flow into the standpipe, then into the distributor header. From there water flows through holes into plant water tubes and out to the plant clusters. All of the openings in the system allow for finely suspended matter to flow through so that waste water may be used. This system allows for easy adjustment of flow rates, while solving the water loss problems by limiting the area wet and eliminating the spray. The results are low water and energy usage, along with efficient plant nutrient application with minimal ground water pollution.

  • Patent number: 5333639
    Abstract: An illuminated siphon includes a directional light source attached adjacent the upper end of the siphon tube. The siphon includes a transmission path for the light source along the siphon inlet tube, with an illumination emission point near the inlet end of the siphon tube, and provides utility for the siphon in darkened and confined areas, such as vehicle fuel tanks. The light source and transmission path are disposed to one side of the siphon inlet tube, thus allowing a clear sight line for the operator along the opposite side of the tube. The inlet end of the siphon tube is inserted into the tank and the light source is activated, whereupon the siphon tube may be maneuvered to observe any water or other contaminates in the tank and to position the inlet end of the tube to withdraw those contaminates from the tank. The tube or pipe to which the light is attached is preferably relatively inflexible in order to provide for maneuverability of the light and inlet end from the opposite end.
