Abstract: 999,954. Scattering granular material. N. LAING. Jan. 18, 1962 [Jan 18, 1961], No. 1965/62. Heading A1D. [Also in Divisions A5, B1, B7, B8 and G3] Granular material such as seed is scattered over land by a helicopter attached by a hose 7 to a road vehicle 8, Fig. 1, or to a fixed tower. Compressed air is conveyed up the hose 7, and carries the granular material with it, separation occurring on the helicopter, which uses the compressed air as an energy source. In Fig. 17, the compressed air and material enter a chamber 83 by a pipe 85, the compressed air passing through a rotor hub 84 to the blades 1. The material falls to the bottom of the chamber 83, whence it is fed to discharge ports 93 by worm mechanisms each comprising a steel rotor 89 driven by an electric motor 90, and a rubber stator 91, so that the material is fed along to ports 93, but a seal is provided at all times against loss of compressed air pressure. In Fig. 16, the granular material is conveyed from chamber 73 between two endless belts 78, 79 of elastomeric material into a chamber 70 at atmospheric pressure, the belts providing a pressure seal. The granular material is scattered from outlets at the ends of the tubes 72 in the rotor blades by the centrifugal effect of the rotating blades. In another embodiment, Fig. 15 (not shown) the compressed air and material is admitted alternately to each of two separating chambers, one chamber being opened to discharge its collected material into a temporary storage container while the other chamber is connected to the compressed air hose 7, and vice versa. Where the helicopter is fed from a fixed tower, it may be constrained, by varying the length of the hose, to fly in an inwardly or outwardly spiralling path. Otherwise, the helicopter is controlled from the ground. The hose 7 passes over a guide pulley which may be on a mast on the road vehicle as in Fig. 1. Where this will not keep the hose clear of the ground, the pulley may be held above the road vehicle by a further helicopter. A plurality of helicopters supplied by a common hose may be flown in formation.
