Abstract: A water geyser assembly comprises an inner pressurizable container and an outer shell both formed from a glass fibre reinforced plastics material. A polyurethane foam material fills the void defined between the inner container and the shell. A fitting mounting land formed with a number of apertures is provided at one end of the inner container for receiving fittings in the form of a pair of flanged spigot portions which are externally threaded and which are bridged at the flange.

Such an application is useful in a method for applying a cover member, such as an elastomeric membrane or insulation board, to a roofing substrate by first positioning the membrane adjacent a work area, then dispensing multiple beads of an adhesive onto the substrate in a preselected spacing and in a single pass and contacting the adhesive beads with the cover member.

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.
