Abstract: An implantable device comprising a driving unit and a kinematic assembly joined together: the driving includes, in an hermetic capsule, electromechanical component, like an electric motor and, the battery pack, and electronic elements, while the kinematic assembly includes a reducer and an actuator, for example a lead-screw distractor, and is lubricated by body fluids. Mechanical energy is transmitted without contact from the former to the latter by a magnetic transmission.

Abstract: A method for producing an electromotor includes: producing laminated cores to form a segmented part including teeth and grooves, two adjacent laminated cores having a partial tooth at ends arranged at a transition point between the two laminated cores; arranging the laminated cores to form a transition tooth from the partial teeth at the transition point of the two adjacent laminated cores; enclosing of each transition tooth by a transition coil; supplying heat at each transition coil to make adhesive an outer thermoplastic layer surrounding a conductor wire of each transition coil and applying pressure to each transition coil in a direction of a floor of the two grooves surrounding each transition tooth to press together the two partial teeth forming the transition tooth; and hardening the outer thermoplastic layer.

Abstract: An electromotor, in particular a linear motor, includes a segmented part formed by elementary laminated cores. On the side of a transition to an adjacent elementary laminated core, each elementary laminated core has a partial tooth, two partial teeth of two adjacent elementary laminated cores forming a transition tooth around which a transition coil is wound. The transition coil is pressed against the floor of the two grooves enclosing the transition tooth such that the two partial teeth remain pressed against each other and thereby provide a rigid connection of the segmented part.

Abstract: The invention relates to a system for interconnecting memory slot machines, for example parking meters or ticket vending machines. Each slot machine (B.sub.1, B.sub.2, . . . ) includes a circuit (C.sub.1, C.sub.2, . . . ) which receives data to be transferred. These circuits are interconnected by a seizure loop (18; 20, 22) and by a data transmission loop (26, 28). When information becomes available at a slot machine, this causes the seizure circuit to be powered up, thereby supplying power to the data transfer loop and to the data-receiving circuits (C.sub.1, C.sub.2, . . . ) of the other slot machines. Once the information has been transmitted to the other slot machines, the above-mentioned circuits are no longer powered.
