Abstract: A magnetic actuator including a mobile magnetic part, a fixed magnetic part, and a mechanism for triggering displacement of the mobile magnetic part relatively to the fixed magnetic part. At least two amagnetic supports, placed in different planes, delimit a gap between them, the fixed magnetic part being integral with at least one of the supports. The supports each have an abutment area for the mobile magnetic part, the abutment area being distinct from the fixed magnetic part. The mobile magnetic part is in levitation in the gap between both supports by magnetic guiding due to the fixed magnetic part when it does not abut against the abutment area of one of the supports. The mobile magnetic part can assume plural stable magnetic positions; in each of these positions, it abuts against a support.

Abstract: This magnetic actuator comprises a fixed magnetic part (3) cooperating magnetically with a mobile magnetic part (1) and means (4) for initiating movement of the mobile magnetic part (1). The mobile magnetic part (1) comprises at least one magnet (1-1) and the fixed magnetic part (3) has at least two attraction zones (3-2) onto which the mobile magnetic part is able to come to attach itself. The mobile magnetic part (1) levitates when it is not attached to one of attraction zones (3-2), its movement being magnetically guided.

Abstract: An electrolytic reactor including a conical recess of removable slices through which the electrolyte circulates towards a part to be coated under the action of a pump setting up forced circulation. The part is polarized to act as a cathode, facing a coaxial anode in the recess. This configuration leads to good electrolyte flow in front of the part, allowing accelerated deposit with a uniform thickness of the coating material, and dimensions of the chamber may be added.
