ABSTRACT:
A system for controllable delivery of a suitable particulate material in dry form from a vehicle for treating waterborne spilled oil. A dispensing module of the system includes base means for defining a base, air compressor means, tank means for holding the particulate material, a feed conduit connected for pressurization by the air compressor means and having an outlet, a downwardly directed nozzle fluid connected to the outlet and supported from the base, means for feeding the particulate material from the tank means into the feed conduit whereby a stream of the material, mixed with air, is directed at high velocity from the outlet, and means for carrying the base by an airborne vehicle with the nozzle elevated above the surface level, the stream impacting and penetrating the oil. The module can be suspended below a helicopter by means of a stabilizer unit. Alternatively, the module can be suspended in registration with landing gear members of the helicopter. In a preferred configuration, the nozzle is located at the end of a downwardly sloping boom assembly of the module, the nozzle also having fore and aft adjustment capability for compensating forward movement of the helicopter.
