Abstract: A method and apparatus for producing an image defined by fluid bubbles in a medium fluid. Alphanumeric digits and/or graphic images in a fluid medium are formed by injecting into the fluid medium a multitude of fluid bubbles having a density different than that of the medium fluid. Using non-gaseous fluids, the fluid bubbles take on a natural shape which is not confined by any structures as it travels through the medium fluid. The rate at which the fluid bubbles rise or fall through a medium fluid is directly dependent on the viscosity of the individual fluids and the difference between the fluid viscosities. The viscosity of the medium fluid also influences the rate of formation of bubbles which are being created. The control and timing circuitry determines the time interval wherein each horizontal row of bubbles is created. The rows of bubbles then create a 2-D or 3-D image, conducive for various applications as signs or displays.

Abstract: Pressurized fluid enters by way of the flow control valve 90 which regulates flow and thus simulated raindrop size, through the fluid supply tube 80 and enters the fixed fluid distributor body 20, past a rotational seal 154 and into the rotating shaft 10, cushioned by the accumulator chamber 50. As the rotating shaft is made to rotate by means of the drive motor 60 and transmission means 70, the radial outlet port(s) 14 sequentially line up momentarily with each side port 26, allowing fluid flow through each outlet tube 30-35 in turn overflowing each respective conical vessel 40-45 to create a fluid drop at the lower point 48 which falls as simulated rain 160 in a desired three dimensional array. Each raindrop is thus timed perfectly according to the speed of rotation of the rotating shaft 10. The transducer 100 produces an electrical pulse for each rotation, also perfectly timed to the raindrops, which is input to the triggered oscillator 110 to ultimately control the strobe light 140.
