摘要:
A filtration and dispensing system that is particularly suitable for underdeveloped parts of the world is provided for storing, filtering, and dispensing rainwater, surface water, or groundwater. The system includes a bank of ceramic filters, a water retention container for holding water to be dispensed by the system, and at least one header tank to which water supplied from the water retention container is fed. A pump is utilized to withdraw water from a lower portion of the water retention container and supplied to the header tank. The withdrawn water is distributed by way of piping from the header tank to individual ceramic filters in the bank of ceramic filters, and a collection tank receives filtered water discharged from the bank of ceramic filters. Trickle feed nozzles or other discharge elements are used to discharge the filtered water from the collection tank for use.

A water harvesting sports arena system includes a stadium seating area, a playing surface operating as at least a part of a water catchment arrangement, and a water reservoir, which may be a segmented tank, positioned below the playing surface to receive and store water passing through the playing surface. A water discharge arrangement is associated with the water reservoir so that water is dischargeable from the water reservoir for consumption or other uses. The stadium seating area is advantageously impervious to water so as to direct water toward the playing field for capture.

A carbon fiber-reinforced cement mould is provided which is capable of being thermally cycled continually at temperatures up to 200.degree. C. Such mould is particularly suitable for casting or forming plastic articles which require heating up to 200.degree. C. to effect curing. Because the mould remains free from cracking and surface spalling during such thermal cycling, it can be used over and over again.

A portable, selectively deployable power supply and storage arrangement includes a frame, a floor securable to the frame and having a longitudinally extending guide member provided thereon, a mast assembly having a first end pivotally connected to a tractor element slidable along the guide member and a second end opposite the first end, and a wind turbine receivable at the second end of the mast assembly. A support is pivotally connected to and extends between both the frame and a portion of the mast assembly so that, upon displacement of the tractor element along the guide member, the support produces movement of the mast assembly between retracted and deployed positions. To facilitate transportation and relocation of the power supply and storage arrangement, the frame, the floor, the mast assembly, the wind turbine, and the support are configured to define a single unit and are collectively receivable in a shipping container.

Method of incorporating carbon fibers into an aqueous hardenable hydraulic cementitious matrix to produce a formable composition which can be set to produce a reinforced structure having improved flexural strength, and improved resistance to cracking and spalling, which employs a polyethylene oxide in an amount sufficient to effect separation of the individual fibers of the fiber strands present in the mix and uniformly disperse them throughout the mix.
