Abstract: In a device for spooling and unspooling a power cable or the like on relative displacement of two areas connected to each other by the cable or the like, spooling and unspooling of the cable are powered by an asynchronous motor whose output shaft is permanently engaged without slip with the cable spooling and unspooling drum. The speed and rotation direction of the motor output shaft are controlled in relation to the measured tension in the cable by variable frequency control of the supply of power to the motor to maintain the tension at an approximately constant value. Provision is made for applying calibrated undirectional braking to the output shaft of the motor in the direction corresponding to the cable unspooling direction. This maintains motor control during unspooling of the cable.

Abstract: A paying out/winding in device eliminates torsion in a line in a rotary connection betweeen a fixed member and a mobile member to which respective ends of the line are fixed. This device comprises a fixed spool carrying a relatively small number of turns and fastened to the fixed member. A mobile spool near and coaxial with the fixed spool carries a relatively small number of turns and is fastened to the mobile member. An arm rotatable about the axis of the fixed and mobile spools carries a satellite pulley at its free end. It is rotatable about an axis inclined at a relatively small angle to the axis of the fixed and mobile pulleys. When rotating more slowly than the mobile spool, it transfers line from the mobile spool to the fixed spool or vice-versa. The arm is rotated by a system which comprises at least one sliding coupling having a primary member, a secondary member fastened to the arm and a first freewheel mechanism coupling the primary member to the mobile spool.
