| Abstract: |
The invention relates to a method and apparatus for creating a fluid screen for use in entertainment. Provided is a mechanically simple and effective way of creating a fluid screen which facilitates the projection of still and moving pictures upon it. The fluid screen is generated by pumping water, or other comparable fluid, through a fluid screen nozzle having an axial flow director and a nozzle insert. The fluid, at a given pressure and flow rate, is directed through the axial flow director, past the internal end of the nozzle insert and its transition section and then onto and away from its radial stabilizer. The fluid is guided by the radial stabilizer of the nozzle insert to form the fluid screen. Each of the regions mentioned contribute to creating the desired shape of the projection surface. Performance may be further enhanced by having a flow straightening area adjacent to the axial flow director, a reducer prior to the nozzle insert, and texturing the surfaces of the transition section and radial stabilizer.

First Claim:

We claim:
1. A fluid projection screen nozzle for creating a fluid projection screen, the fluid projection screen nozzle comprising:
- an axial flow director for directing a flowing fluid axially toward a fluid exit, said flowing fluid having a flow direction; and,
- a nozzle insert positioned at said fluid exit, said nozzle insert comprising:
- a flow restrictor rigidly affixed within said axial flow director at said fluid exit, said flow restrictor reducing the area of fluid flow within said axial flow director thereby increasing the velocity of the flowing fluid;
- a transition element for smoothly changing said flow direction from axial to substantially radial, said transition element having a first end downstream of and contiguous with said flow restrictor, an opposed larger second end, and a curving surface resembling a segment of a bell by flaring outwardly therebetween for smoothly transitioning direction of said flowing fluid from axial to substantially radial, said curving surface extending beyond said fluid exit of said axial flow director; and
- a radial stabilizer attached to said second end of said transition element to stabilize and complete the transition of the direction of said flowing fluid from axial to substantially radial, whereby said flowing fluid continues beyond said radial stabilizer to form said fluid projection screen.
