Abstract: A device for the controlled dispensation and unattended evaporation of volatile liquids includes a housing that accommodates a reservoir charged with a volatile liquid. The reservoir has an outlet for releasing the volatile liquid from a lower end of the reservoir. A valve mounted on the reservoir controls the flow of the volatile liquid through the reservoir outlet. The valve allows a controlled quantity of the volatile liquid, in the form of discrete droplets, to be gravitationally delivered, on demand, to an absorbent matrix. A matrix housing supports the matrix below the reservoir outlet. The absorbent matrix absorbs volatile liquid that the outlet delivers and dispenses the volatile liquid as a vapor to an external environment. The absorbent matrix dispenses the vapor via a ventilator that may be either releasably or integrally mounted to either the matrix housing or the housing that accommodates the reservoir.

Abstract: The humidification device includes a tube formed of gas permeable material connected to a water source by a tube formed of material that is substantially impermeable to water. The gas permeable tube permits water to evaporate through the tube wall and is thus an evaporation tube. The evaporation tube is disposed in a chamber that is to be humidified. As water evaporates from the evaporation tube, the humidity in the chamber builds up to a maximum level. At the maximum humidity level evaporation of water from the evaporation tube ceases. When the humidity level in the chamber drops below the maximum level, evaporation of water from the evaporation tube resumes to restore the humidity in the chamber to its maximum level. Water flow from the water source replaces evaporated water from the evaporation tube. The humidification device is thus self-regulating and does not require any water flow regulating devices. One or more water flow tubes can be connected to the evaporation tube from a water source.

A second end of the wick extends through an opening in a cap that is threaded to the collection container. The supply container is suspended in an inverted manner so that the game luring scent flows downwardly along the wick where the scent becomes airborne by air currents. Excess amounts of the scent which flow down the wick continue to flow into the collection container where it is collected and stored for later use.

Abstract: Apparatus including a liquid vaporizer having a first wick of linear shape, a bottle for holding the liquid to be vaporized and a gravity-flow metering device having a second wick. The bottle has a closing cap to which two tubes are connected.

The end of the discharging tube extends outwardly of the cap further than the end of the other tube so that a pool is produced in the dispenser. The level of the pool is limited by the position of the end of the tube for counteracting the vacuum. The second wick is of J-shape; one end is immersed in the pool and the other end is suspended over the first wick so that liquid absorbed at the immersed end drips from the second wick on the first wick and is evaporated and diffused from the first wick.

Abstract: A device for dispensing any one of a wide range of volatile liquids as vapours, comprises a reservoir with an open end closed by a vapor-permeable, liquid-impermeable element. A flange surrounds the opening to the reservoir and the element is bondable to the flange in a multiplicity of different locations, each of which defines a respective area of the element bounded by the bond and wettable by the volatile liquid. Thus, a single device can be used to dispense any one of a wide range of volatile materials simply by determining the surface area within the bond to be wetted by the volatile liquid to give the desired rate of vapor release for the selected volatile material and bonding the element to the flange in a location to define the determined wettable area of the element.

Abstract: A water distributor is disposed above an air-liquid contact pad, and is supplied with water from a supply line. The water is received within an elongated enclosed chamber having at least one elongated corner in its lower portion. A floor portion of the chamber is formed of an imperferate slightly flexible wall disposed generally tangential to the corner. A screen is disposed on the inner surface of the floor portion and is manually adjusted to engage with the said corner in a line contact relationship to form a water flow restriction or gap. The chamber above the restriction is sealed. During each cycle of operation, as water initially flows into the chamber, a miniscus forms at the gap which prevents water discharge. As the chamber fills with water, the air thereabove is trapped and pressurized and, together with the pressure of the accumulating head of water, gradually increases the pressure on the miniscus.
