The self-contained miniature laminar ornamental fountain shown in FIG. 1 comprises an enclosure and water reservoir, 5, a pump, 1, flow control means, 3, pipe or tubing means 5 to conduct water from the pump, 2, to a laminar nozzle, 6. Water in the reservoir, 1, enters the pump, 2, where it is pressurized, thence through the adjustable valve or flow control means, 4, through the tubing, 5, to the laminar nozzle, 6. The laminar stream, 7, emanating from the laminar nozzle, 6, forms a graceful arch and then falls back into the reservoir, 1, to repeat the cycle. In another embodiment of the invention the fountain includes one or more additional laminar or non-laminar nozzles nozzles. In another embodiment the fountain above in which the laminar nozzle(s) contain internal lighting means for producing lighted laminar streams. In another embodiment in the fountain, the laminar stream(s) are interrupted to form jets of water which appear to leap from place to place.

1. An improved mimature laminar nozzle fountain assembly comprising: a fountain enclosure including a water reservoir; means for causing fluid to enter the nozzle assembly; a diffuser located within said assembly; said diffuser comprising a porous filter formed into a hollow hemisphere having a generally convex surface and a generally concave surface; said generally concave surface having a center spaced from said generally concave surface; an exit orifice spaced from said generally concave surface and located generally at said center, whereby as said fluid flows through said hollow hemispherical diffuser it has its Reynold's Number significantly reduced, and any turbulences on said convex surface tend to be converted to a very great number of micro-turbulences which tend to be self canceling and substantially all water flowing from the diffuser to the exit orifice has substantially the same distance to travel from substantially all directions, and the fluid exiting said orifice is highly laminar; said mimature laminar ornamental fountain being sized to be set and displayed on a table top; and whereby said highly laminar stream emanating from said laminar nozzle forms a graceful arch and then falls back into said reservoir. 2. An improved nozzle assembly according to claim 1 wherein said diffuser is made of polyester fiber air filter material. 3. An improved nozzle assembly according to claim 2 wherein said material is about 1/2 inch to 1 inch thick. 4. An improved nozzle assembly according to claim 3 wherein material has been heat formed over a hemispherical mandrel. 5. An improved mimature laminar nozzle fountain assembly comprising: a fountain enclosure including a water reservoir; a generally cylindrical nozzle body having an exit orifice, a continuous wall and an end opposite from said exit orifice; an inlet port for causing fluid to enter the nozzle assembly radially though said wall toward said end; a diffuser located within said assembly; said diffuser comprising a porous filter formed into a hollow hemisphere having a convex surface and a concave surface having a center; an exit orifice located generally at said center; a blade located on the inside of said wall directly in front of said inlet port, whereby water entering through said inlet port is forced to flow in a generally circular direction flow, whereby said circular flow will tend to distribute water flow and turbulence evenly whereby as said fluid flows through said hollow hemispherical diffuser it has its Reynolds Number significantly reduced, and turbulences on said convex side of said diffuser tend to be converted to a large number of micro-turbulences which tend to be self canceling and substantially all water flowing from said diffuser to the exit orifice has substantially the same distance to travel from substantially all directions, and the fluid exiting said orifice is highly laminar; said mimature laminar ornamental fountain being sized to be set and displayed on a table top and whereby said highly laminar stream emanating from said laminar nozzle forms a graceful arch and then falls back into said reservoir. 6. An improved nozzle assembly according to claim 5 wherein said diffuser is made of polyester fiber air filter material. 7. An improved nozzle assembly according to claim 6 wherein material has been heat formed over a hemispherical mandrel. 8. An improved nozzle assembly according to claim 6 wherein said material is about 1/2 inch to 1 inch thick.
