Line dispensing devices include a coupling transmission, a retraction mechanism, and a rotor that rotates around a shaft. Rotation of the rotor causes a portion of at least one pivotable member to move into and out of a magnetic field.

A generator system having a dynamo that contains an armature, a stator and a housing. The armature rotates about a first axis of rotation. The stator is concentrically positioned around the armature. Both the armature and the stator are free to rotate in opposite directions about the first axis of rotation. The housing of the dynamo is connected to a motor that can rotate the dynamo around a second axis of rotation. There is an angle of inclination between the first axis of rotation and the second axis of rotation. This angle of inclination is selectively altered during operation. By changing the angle of inclination between the two axes of rotation, a precession can be created that adds rotational energy to both the armature and the stator. This increases the output of the dynamo and creates a highly efficient electrical generator.
