Abstract: The invention relates a water storage and storm water collection and detention system including at least one storage reservoir integrally attached to and extending along the edge of an extremity of a roof of a building structure; wherein the storage reservoir directly receives run-off from the roof. The system further includes at least one outlet, a supply line in communication with the outlet, an overflow outlet, and a float valve assembly connected to the supply line such that the reservoir communicates with a mechanism that allows for the water collected therein to be used with a water consumption apparatus or tap line on demand.

Abstract: A dispersion device for spreading liquid over heat transfer surfaces. A tube shaped central element has guide elements in its interior which extend out of the central element's bottom end pointing away from the longitudinal axis of the central element channeling and dividing liquid flow into a pattern of liquid trickles.

Abstract: An improved method and apparatus for producing a dispersion of substantially immiscible liquids which employs a conduit having an upstream section divided into first and second channels of variable length and a downstream section for mixing the liquids. The apparatus also includes means for varying the length of the first and second channels and means for flowing the liquids separately through the channels whereby the liquids mix in the downstream section of the conduit to form the dispersion. In accordance with one embodiment, a conventional mixer-settler is modified to include the conduit mounted at an upstream end of the settling chamber so that its inlet is adjacent the mixing chamber and its outlet is approximately at the same height as the organic-aqueous interface in the settling chamber.
