Abstract: A recirculating water fountain configured for table/desk top use comprises a water reservoir, a plenum mounted above the reservoir and configured to accumulate a substantially still pool of water, and a pump operable to pump water upwardly from the reservoir to form the water pool in the plenum. The recirculating water fountain includes a visually open flow pathway sloping downward from beneath the plenum to receive water from a plenum overflow for return to the reservoir, and a controller for alternately defining a pump-on mode and a pump-off mode. The pump controller functions to define the pump-off mode in response to the water level in the reservoir falling below a first height mark and to prevent resumption of the pump-on mode until the water level in the reservoir exceeds a second height mark.

Abstract: The present invention relates to a water director for distributing a surge or flow of water to one or more of a plurality of output ports, which can vary in shape, size, and number, typically for use in marine and fresh water aquariums. Water pumped through a conduit into the hermetically sealed Switching Current Water Director (SCWD), powers an internally mounted gear driven fluid motor, which turns a rotational valve, alternately opening and closing a plurality of water outlet ports. When mounted externally to an aquarium, proper placement of output nozzles, which are connected to a water conduit attached to the various SCWD outlet ports, provides the desired opposing, or switching back and fourth currents. Depending on the inlet and outlet port configuration, the SCWD can be adapted to suit many applications.

Abstract: A natural waterfall is simulated by introducing water into an inlet box that includes a spreader for dividing the incoming stream into two laterally flowing streams that are reflected off the sidewalls of the inlet box and which collide against each other to suppress the turbulence of the incoming stream in the absence of baffle walls. The inlet box has an outlet in open communication with an outlet box through which the water flows to create the waterfall. In a second embodiment, an open-faced structure includes a back wall, side walls, and a bottom wall, and the waterfall apparatus is positioned against the back wall so that its outlet faces the open front end of the structure. Rocks are then added to fill the structure. The walls of the structure constrain the water to flow down the face of the rocks. This enables a rock waterfall to be built by inexperienced personnel.

Abstract: The present invention is an apparatus for creating a "pop jet" type of ornamental fountain with an output stream in the form of surface-tension envelope or "ball" of fluid, embedded with air bubbles. By virtue of the laminar nature of the fluid created, the natural surface tension of the fluid prevents the envelope from flying apart into multiple fluid drops. The envelope therefore can be created much larger than has been possible previously. Previous attempts at building "pop jet" type fountains have been limited to creating relatively small envelopes due to the internal turbulence of the fluid. The present invention minimizes internal turbulence by utilizing various advances in envelope shape, outlet orifice design and diffuser strucutre. It enhances the size of the envelope produced by adding fluid and air bubbles outside the outlet orifice by directing the output stream sthrough a secondary pool of fluid.
