Abstract: A construction kit for a spring-driven cable drum includes a pre-assembled drum core, the housing of which constitutes a winding surface for the cable and containing at least one spiral spring and at least one spring anchor hub. The pre-assembled drum core is provided with an axle channel passing right through it but no axle. The spring anchor hub is maintained to all intents and purposes coaxial with this axle channel by the spiral springs. The construction kit further includes a separate axle which can be inserted from either side into the axle channel of the pre-assembled drum core, insertion of the axle into the axle channel establishing a form-fit rotary coupling between the spring anchor hub and the axle.

Abstract: A device (10) for supplying preconditioned air to an aircraft on the ground, comprises a compressed air inlet (16) and a compressed air hose (34) having a first end connected to the compressed air inlet (16) and an opposite second end for connect to a remote, ground-based, compressed air unit. Expander means (14) are situated downstream of the compressed air inlet (16) for allowing the compressed air to expand to lower pressure and temperature. The device (10) further includes an ambient air inlet (24) and a mixing chamber (22) downstream of the expander means (14) and communicating with the ambient air inlet (24) wherein mixing of ambient air with the expanded, cold air is controlled in such a way as to elaborate preconditioned air at the desired temperature. A connection hose (28) has a first end in communication with said mixing chamber and a second end to be connected to an aircraft on the ground.

Abstract: A motorized trolley (10) for suspension from and travel on a rail (12) comprises first and second supporting wheels (14) for location on and engagement with opposite sides of the rail; the first supporting wheel comprising a first shaft (18-1) for rotating the first wheel (14-1) and the second supporting wheel (14-2) comprising a second shaft (18-2) for rotating the second wheel. Driving motors (16) are associated with the shafts for rotating the supporting wheels. Third and fourth supporting wheels may also be driven by motor. The motors are directly connected to the shafts of the supporting wheels.

Abstract: A magnetic hysteresis clutch comprises a rotor supporting a ferromagnetic hysteresis material and a rotary magnetic inductor capable of inducing a magnetic field in the ferromagnetic hysteresis. The magnetic inductor and the ferromagnetic hysteresis clutch is constructed so that an increase in the magnetization losses in the ferromagnetic material, which accompanies an increase in the slip between magnetic inductor and the ferromagnetic hysteresis, leads to a reversible increase in the temperature of the ferromagnetic hysteresis material, and thereby to a reversible decrease in magnetization of the ferromagnetic material which is sufficient to bring about a desired decrease in the transmitted torque. Thus it is possible to provide a magnetic hysteresis clutch in which the transmitted torque reversibly decreases when the slip increases.

Abstract: A magnetic hysteresis clutch comprises an external rotor and a rotary magnetic inductor arranged in said external rotor so as to define a radial air gap. Rings of ferromagnetic hysteresis material are mounted in said external rotor so as to be able to undergo a reversible thermal expansion of their internal diameter leading to an increase in the radial air gap. The clutch is designed so that the heating up of the ferromagnetic material in the rings which accompanies an increase of the slip between the external rotor and the rotary magnetic inductor, produces a reversible increase in the radial air gap which is sufficient to decrease the transmitted torque. Thus it is possible to provide a magnetic hysteresis clutch in which the transmitted torque reversibly decreases when the slip increases.

Abstract: A cover belt for a duct is presented, which can be swung up from a closed position by a deflecting device movable in the longitudinal direction of the duct and falls back in its closed position behind the deflecting device. The cover belt is made of a flexibly deformable material with metallic reinforcements. The cover belt is comprised of a securing strip, a joint strip and a cover strip. The securing strip is secured along the duct, the joint strip connects the securing strip flexibly to the cover strip, and the cover strip spans the duct and is supported on both sides of the duct. At least one belt-shaped textile reinforcement layer with essentially the same overall width as the cover belt is embedded in the flexibly deformable material in the area of the neutral plane of the cover belt.
