Abstract
578,369. Mineral oil compositions. HURLEY, T. F., and WILKINS, E. T. Nov. 15, 1941, Nos. 14726/41, 14727/41 and 16208/42. [Class 91] [Also in Groups X, XXIX and XXXIII] Apparatus for applying a film of waterproofed dust to the surface of water to reduce its visibility from the air comprises means for discharging the dust in a current of fluid such as air in such a manner as to disperse the dust on the surface of the water. In the apparatus shown, which is mounted on a boat, the dust is stored in a hopper 3 from which it is drawn by conveyers 4, 4<1> driven by engines 5, 5' and discharged into the air inlets of two blowers 6, 6' driven by an engine 7. An oil pump 8, also driven by the engine 7, supplies oil to two sprayers 9, 9' discharging into the inlet ducts of the blowers 6, 6<1>. The same pump may also supply oil, e.g., marine fuel oil mixed with three times its volume of paraffin burning oil, on to the water at the stern of the boat. The dust particles become oil coated in the blowers and are carried through ducts 10, 10' to be discharged into the water by hose pipes 11 having holes 13 just below the surface. Preferably coal containing 85 to 91 per cent. of carbon ground as finely as that commonly employed for powdered fuel firing is employed, the particles being waterproofed by 0.5 to 5 per cent. of fuel oil with or without paraffin oil.
