Abstract: A system of modular artificial rocks provides aesthetic appeal to a landscape. The system comprises at least two rocks, one stacked on the other and interlocked to each other, as by a tongue and groove arrangement. The rocks have respective back ends that overhang. The back ends of all but the bottom rock of a stack are supported off the ground. In a modified embodiment, the back ends of the rocks align in vertical planes. There may be one back end, in which case the rocks can be placed flush against a fence or a building wall. In another embodiment, there are two back ends. Two or more stacks of modular rocks are placed with their back ends in flat facing contact. For example, the back ends of the rocks of each of three stacks may subtend an angle of 120 degrees. A waterfall can be incorporated into any of the stacks. The bottom rock of a stack has a depression that acts as a reservoir. Water is pumped to the top of the top rock of the stack, from where it flows back to the reservoir.

Abstract: A floating liquid aerator includes an axial flow impeller rotated by an electric motor and disposed within a tubular throat to pump water from a pond upwardly through the throat and against a rotatable diffuser which slings the water outwardly for interface contact with the surrounding atmosphere. Being rotatable, the diffuser slings the water into the atmosphere with considerable turbulence thereby exposing more of the water droplets to the atmosphere and resulting in a higher transfer of oxygen to the water. The impeller comprises a series of angularly spaced blades formed with a rectangular cross-section to reduce power losses caused by drag and to increase the volume of water capable of being displaced by the impeller. Each blade is twisted longitudinally with a progressively decreasing attack angle from its root to its tip and, in addition, all of the blades are twisted identically to provide a statically, dynamically and hydrodynamically balanced impeller. .Iadd.
