Abstract: A display where lights may be programmed to randomly flash is described. The randomness may be changed by changing the mode of flashing. The lights may extend along strings that are powered by a power supply that may itself be plugged into a socket that had previously served as a light socket. The display may be added to existing displays to enhance existing visual effects. The display may be submerged and the lights may remain upright because of their buoyancy.

Abstract: A balloon valve that can control the flow of a display fluid through the supply pipe of a water display. The supply pipe is typically suspended from a structure and releases a slug of water into a pool. The pipe is located at a distance from the pool so that the water slug breaks up into a rain shower. The balloon valve includes an inflatable hose located within the supply pipe and coupled to a source of pressurized working fluid. The flow of working fluid into the balloon valve is controlled by a control valve. When the control valve is in a first state, working fluid flows into the balloon valve to expand the hose. The hose is expanded to completely fill a portion of the pipe and prevent the display fluid from flowing through the pipe. When the control valve is in a second state, the balloon valve is deflated so that the display fluid can again flow through the supply pipe and out of the display.

Abstract: An air powered water display nozzle unit which has an adjustable nozzle coupled to a housing by a support plate and a plurality of springs.

Abstract: A water display that has a container with a floor that defines an inner cavity. The container has a top opening adapted to allow a fluid to flow into the inner cavity at a first predetermined flowrate. The floor is constructed to contain the fluid when the fluid flows into the inner cavity, such that the fluid reaches a first predetermined level within the container. The floor also has a floor opening adapted to allow the fluid to flow out of the inner cavity. Within the container is a valve operatively connected to the floor opening that allows the fluid to flow out of the inner cavity at a second predetermined flowrate, when the fluid level reaches the first predetermined level. The second flowrate being greater than the first flowrate, such that when the valve allows the fluid to flow out of the container, the fluid level in the inner cavity decreases until the fluid level reaches a second predetermined level.

Abstract: Water displays utilizing laminar flow streams to create dynamic arch-like displays are disclosed. The laminar flow nozzle is mounted on an assembly for changing the angle and repositioning the laminar flow nozzle so that the laminar flow stream appears to eminate from a fixed location at different angles, which allows varying the characteristics of the display in a dynamic manner. Simultaneous control of the nozzle position and angle with control of the pressure of water supplied thereto allows the stream to be varied to create a dynamic display with the stream returning to a sink region at a fixed position independent of the height of the water stream. Illuminating the laminar flow stream internally causes the same to glow like a fluorescent tube with the color being supplied thereto, changeable as desired. Intersecting laminar flow streams provide interesting water formations, with the intersections of two streams of different colors causing still a third color at the flared region of the intersection.

Abstract: A wave generator for generating waves in pools and the like for water sports, amusement and the like. The wave generator has a water inlet/outlet disposed and configured so that when acting as an inlet, it will draw water from the pool and not air from above the pool. The wave generator includes a sealable chamber coupled to the water inlet/outlet for temporary storage of a substantial quantity of water at elevations above the level of water in the pool. In operation the chamber is sealed and air is pumped therefrom by a suitable air pump, by an entrainment device or other equipment, substantially filling the chamber with water from the pool. To generate a wave, the upper part of the chaber is then vented to the atmosphere, allowing the water in the chamber to rush out through the inlet/outlet thereof, with the sudden rush of water generating the desired wave. Various embodiments are disclosed.
