  • Apparatus for projecting water to form an insubstantial screen for receiving images
    Patent number: 5445322
    Abstract: An apparatus projects water under pressure to form a screen (1) made of transparent droplets (2) that can reflect rays of light (3) striking the screen by back-projection (4). It includes a substantially vertical dispersal plate (7) that is disposed on the trajectory of the water driven substantially without swirling by a high-pressure pump (8) in a substantially horizontal conduit (9), the end of which is mechanically joined to the dispersal plate (7) and with it defines an upper opening (10) providing an outlet for a vertically oriented sheet of water. The invention is applicable to projection apparatus for sound and light shows.
