The aircraft has two wings (2), the surface of the projection of said two wings in a horizontal plane representing less than thirty percent of the entire lift area, and the wings being located in said third fifth (15) or fourth fifth (17) of the total length of the fuselage. An elevator unit (4) is located on the last fifth (18) of the fuselage. The longitudinal central profile of the aircraft has a negative curvature, and the longitundal profile of the wings has a positive curvature. The form of the aircraft resembles the form of a fish.

Abstract: An electronic module for regulation of a watch movement with mechanical winding includes a generator (1) permitting converting the mechanical energy supplied by the mechanical watch movement into a measuring signal (G+;G−) and an electronic circuit (11) supplied by the generator. The electronic circuit includes an energy dissipation circuit (9) permitting applying at least two separate braking couples more than zero to the generator (1). The electronic circuit (11) also includes a counter to control the braking circuit. The braking couple selected by the control circuit depends on the advance of the generator and is reduced, without being suppressed, when the measuring signal (G+;G−) passes through an extreme.

Abstract: The electronic circuit allows the control or regulation of the speed of rotation of a microgenerator (1) in a watch movement. It comprises two inputs (G−, G+) connected to said microgenerator, a quartz oscillator (3, 4), an energy-dissipation circuit,(9) for braking said microgenerator, energy-dissipation control means (5, 6, 7, 30, 31) for controlling the energy dissipation of the energy-dissipation circuit as a function of the frequency difference between the signal coming from the quartz oscillator and the signal coming from said microgenerator, and a rectifier and voltage-transformer (2) for rectifying and multiplying the signal coming from said microgenerator, with at least one capacitor (C1, C2, C3) charged by said microgenerator via at least one switch (17, 18, 19). The momentary energy dissipation of the braking circuit can further be reduced when the capacitors are charged.

Abstract: A timepiece movement proposed has a spring which drives, via gearing, a time display and a generator (1) supplying an a.c. voltage. The generator (1) powers, via a voltage-transformer circuit (2), a first capacitative component (10). The first capacitative component (10) powers an electronic reference circuit (3, 4, 5) with a stable oscillator (3, 4) and an electronic control circuit (6, 7, 8, 9). The first capacitative component (10) is charged immediately after the movement is started for the first time by one or more passive components. The one or more passive components are replaced, or supplemented in parallel, by one or more active units as soon as the voltage of the first capacitative component (10) is sufficient to operate the one or more active units, the one or more active units having a lower electrical resistance in the pass direction then the one or more passive components.

Abstract: Micro-generator for a clockwork movement. It contains a rotor provided with two disks and a stator with three coils connected in series. Each disk is provided with six permanent magnets with alternating north-south polarity. The coils are mounted on a module containing an electronic circuit. This circuit controls the speed of the generator in that it compares the frequency of the signal at the output of the generator with a reference frequency derived from a quartz oscillator and changes the load of the generator by means of a variable brake resistance.The micro-generator is constructed in such a way that the peak voltage of the generated signal is as high as possible and the space requirement inertia and frictional resistance of the rotor are kept as low as possible. To achieve this, the coils of the rotor are disposed on the module asymmetrically with respect to the axis of the rotor. The coils can have a maximal surface, the micro-generator being easily mountable.

Abstract: The gliding parachute which is closed at its leading edge comprises substantially in the zone of the highest aerodynamic impact pressure pressurizing air entry openings located in the lower parachute sheet, which openings lead to a stabilizing of the shape of the parachute comprising substantially an upper and a lower parachute sheet forming an air foil structure. In order to inflate this parachute during the starting phase, inflating air entry openings are located downstream of the pressurizing air entry openings, which inflating air openings are designed as check valves. This causes a faster and safer filling of the interior of the parachute by air.
