  • Method and apparatus for generating water sprays, and methods of cleaning using water sprays
    Publication number: 20020030122
    Abstract: A water spray has a nozzle (6) for carrying a pressurised flow of water to an outlet (7) thereof, and a conduit (12) surrounding the nozzle outlet (7) for carrying a flow of gas contiguously around the flow of cleaning liquid exiting said nozzle outlet (7). The ratio of velocities of gas and water immediately downstream of the nozzle is in the range 0.5 to 2. This enables good control of water droplet size in the spray, to a volume median diameter in the range 0.5 to 2 mm at 1 m from the nozzle. Low water pressures may be employed in cleaning using such a spray.

  • Aerosol
    Patent number: 5894964
    Abstract: An aerosol actuator is provided having an inner actuator chamber, an inner actuator chamber outlet by which the composition to be dispensed may exit the inner actuator chamber, and a stem piece channel by which the fluid to be dispensed may enter the inner actuator chamber. The inner surface of the inner actuator chamber is mathematically continuous. The mathematically continuous arrangement minimizes nozzle blockage in the actuator.
