  • Patent number: H109
    Abstract: A smoke generator having an air-powder mixing container with vacuum line achment to a mechanical smoke dispersing apparatus. The container has funnel shaped side walls to direct powder to a reduced container bottom. A pressurized input line extends to a point on the container bottom as does a vacuum powder outlet line. The powder outlet line is connected to a venturi mounted to the exhaust port of a small turbine engine.

  • Patent number: H1124
    Abstract: A particle smoke generator having a gas turbine for combusting air and fu and for discharging heated exhaust combustion gases. A venturi tube conveys the heated exhaust gases into a low-pressure region away from the combustion means. A supply of particulate smoke material is joined to a supply tube for conducting the particulate smoke material from the supply to the venturi tube. In the venturi tube the particulate smoke material is deagglomerated by the exhaust gases. The deagglomerated particles and gases are diffused in a diffuser nozzle to generate smoke in the atmosphere.
