Abstract: An aircraft includes a fuselage and a fixed flying surface having two wings, and a cradle-shaped ventral fairing at the crossover of the latter with the flying surface and provided with two longitudinal flanges climbing laterally along the fuselage and being provided with an opening for the passage with play of the corresponding wing to form a first peripheral slot around the ventral fairing and a second peripheral slot around each wing. An elongate seal is fixed to the periphery of the ventral fairing and to the periphery of each opening, so at to shut off the first and second slots, respectively. The seal includes a longitudinal elastic end lip applied, via the inner face of its free end, respectively against the fuselage or the flying surface and a longitudinal leaktightness member, carried by the inner face of the seal set back with respect to the end lip and also able to be applied against the fuselage or flying surface, respectively.

Abstract: Aircraft with ventral fairing and seal for such an aircraft.

Abstract: The invention relates to a suction-type distributor for a single-seed seeder with a rotary apertured disk. The distributor 2 includes an aperture disk 5 rotating in a casing 4 and two adjoining selector plates 16 and 17 pivoted at 13 from the casing and provided with alternate projections 26 and 31 spaced on their edges extending around the path of apertures 6 on disk 5 so as to straddle said path, the relative angular position of the two plates being adjusted by means of a single lever 14 provided with cams 20 and 21 and pivoted at 15 on casing 4.

Abstract: The present invention relates to a seeding machine of the pneumatic ejection type. The seeding machine includes an apertured distributor disk 2 which rotates past a suction chamber 3 terminating in an end wall 4, and an ejector venturi 1 is juxtaposed to the side of disk 2 opposite to chamber 3, neck 7 of said venturi being located in line with the end of said chamber and having an inlet port 8 which straddles the path of travel 5 of the suction apertures in disk 2. The machine has an application to the sowing of light seeds such as vegetable seeds.
