Abstract: A self supporting rubbery flow blocking device of substantial thickness is mounted in a fluid passageway to automatically regulate flow. Due to its variable elastic stiffness, increases in pressure will cause the device to begin to flex away from the pressure, beginning at its free end. Further increases in pressure will cause the location of the flex to move towards the secured edge of the invention, unblocking larger areas of flow. Decreases in pressure will allow the invention to increase its blocked area until it regains its fully blocking state.

A relatively simple protective barrier includes corrugated panels connected end-to-end to define an enclosure, a bar or cap mounted on the panels, a plurality of threaded rods for extending through the cap into the ground, an anchor for mounting on the bottom end of each rod, whereby, when the rod is pulled upwardly, the anchor engages the ground to hold the rod firmly in position, and a nut for mounting on each rod above the bar which can be tightened to push the bar and consequently the panels downwardly into the ground.

Abstract: An elevated wall reservoir system that has a floating cover assembly that lies directly on the top surface of the body of liquid. The peripheral edges of the cover assembly extend beyond the edge of the liquid and are resiliently secured by tension cables that are attached to tension towers. The tension cables hold the cover assembly in position on the top surface of the liquid and permit the cover assembly to travel upwardly or downwardly in response to the liquid level. Thus the cover assembly is always supported by the liquid and tension in the tension cables. The elevated wall reservoir system allows existing reservoirs to be modified to increase their storage volume by twenty or fourty percent without the need of utilizing additional land area. The elevated wall reservoir system can also be used on new installations.
