Abstract: A bypass turbine engine is described. The engine includes a system for bleeding gas from a primary stream to a secondary stream. The system may include two coaxial rings extending one around the other. A perforated internal first ring may be situated at the level of an outer casing and may extend substantially in a continuation of the outer casing. A perforated external second ring may be mounted such that it slides circumferentially on the first ring between a first position in which the perforations of the rings do not communicate with one another and a second bleed position in which the perforations of the rings communicate with one another.

Abstract: A forward and reverse pedaling system for a bicycle with automatic gear change replacing the derailleur and clutch operating at a very low speed using an engagement wheel (16), all enclosed within a housing case filled with oil. The two wheels (11) and (13), which are themselves driven by rods (9) and (10), make a reciprocating to and fro motion of less than a half turn regardless of the direction of rotation of the drive wheel (1) and drive the wheel (12) followed by the driven wheel (2) via the low speed clutch between the wheels (15) and (16). This system can be applied to any mechanical assembly in which it is required, and is not limited to use in bicycles.
