A cycloidal magnetic gear system for a turbine system is disclosed. The system includes a first stator magnet ring, a second stator magnet ring positioned opposite the first stator magnet ring, and a rotor positioned between the first and second stator rings of magnets. The rotor may include a first side positioned adjacent the first stator magnet ring, and a second side positioned adjacent the second stator magnet ring. The system may include a first rotor magnet ring affixed to the first side of the rotor, adjacent the first stator magnet ring. Additionally, the system may include a second rotor magnet ring affixed to the second side of the rotor, adjacent the second stator magnet ring. The rotor may be configured to rotate eccentrically about a center-axis of the first and/or second stator magnet ring.

Le dispositif régulateur (2) de la marche d'un mouvement horloger mécanique comprend: - un châssis (4); - un résonateur fixé au châssis et comprenant une première structure magnétique annulaire (8) ayant un premier nombre N1 d'aimants agencés régulièrement en cercle et une structure élastique (20,21,22); - une deuxième structure magnétique annulaire (14) ayant un deuxième nombre N2 d'aimants et définissant un axe central (1 6) autour duquel elle tourne, N2 étant différent de N1. Le résonateur est agencé de manière qu'un mode de résonance dans lequel la première structure magnétique subit une translation curviligne, de préférence sensiblement circulaire, autour de l'axe central peut être excité par la rotation de la deuxième structure magnétique. Les deux structures magnétiques définissent un engrenage magnétique cycloïdal de sorte que le dispositif régulateur incorpore un réducteur de fréquence entre la fréquence de résonance et la fréquence de rotation de la deuxième structure magnétique solidaire d'une roue d'échappement.

Apparatus for coupling magnetic forces into motive force includes a spinner shaft on which a helical array of magnets is mounted and a magnetic power bed. The magnetic power bed includes first and second magnetic boost elements configured to interact magnetically with the helical array of magnets to cause the spinner shaft to rotate as the helical array of magnets passes between the first and second magnetic boost elements, the first magnetic boost element includes two magnets separated by a magnetically responsive material and the second magnetic boost element includes a single magnet, thereby defining a tri-field magnetic flux within the magnetic power bed. The magnetic power bed may further include an auxiliary power bed that interacts with the first and second magnetic boost elements and the helical array. The apparatus may include two or more magnetic power bed with one or more magnetic field shunt bridges extending between the magnetic power beds.

A permanent magnet is rotated about an axis extending between opposing north and south poles. The magnetic field of the rotated permanent magnet interacts with magnetic fields of permanent magnets carried by a shuttle for repelling and attracting the fixed permanent magnets, and providing a linear reciprocating movement of the shuttle responsive to the favorable rotary motion of the rotated permanent magnet where the force of the linear motion is captured by an energy storage device.

A mechanism for translating reciprocating-motion into rotary-motion has a reciprocatable member connected to a reciprocating input shaft, a rotatable member connected to a rotating output shaft, a separating element situated between the reciprocatable and the rotatable members and a mechanical diode that constrains the separating element to rotate in only one direction. The reciprocatable and the rotatable members have pairs of alternating-polarity, permanent- magnets, while the separating element has ferro-magnetic pole-pieces. In such an arrangement, whichever direction the reciprocating member moves, the rotatable member moves in the same direction.

A device includes a first magnet, a second magnet, and a coil. The first magnet is constrained to move in substantially-linear motion. The second magnet is mounted to move in rotational motion. The first and second magnets are positioned so the substantially-linear motion of the first magnet causes rotation of the second magnet. The coil is adjacent the second magnet, and rotation of the second magnet induces a current in the coil.

The invention relates to a thrust actuator for converting a continuous, that is, cyclically recurring, rotational movement to a discontinuous thrust movement of a permanent-magnet rotor magnet, and to a Stirling engine which particularly benefits therefrom. According to the invention, the rotor magnet is movably mounted such that it can be displaced toward a drive magnet, wherein the polarity of the drive magnet relative to the rotor magnet can be varied by the rotational movement. The rotor magnet can be connected in particular to a rotor which participates in the thrust movement of the rotor magnet. It was recognized that the continuous rotational movement modulates the magnetic interaction between the rotor magnet and the drive magnet periodically between attraction and repulsion in said arrangement. The rotor magnet can thus be moved periodically but abruptly away from and back toward the drive magnet. A discontinuous, periodic thrust movement of the rotor magnet and of a rotor that may be coupled thereto can thus be achieved. The invention further relates to a Stirling engine as a primary application for the thrust actuator.

Transmission de force à contact maîtrisé ou sans contact dans un mouvement d'horlogerie L'invention concerne un procédé de réalisation d'une transmission à contact maîtrisé ou atténué ou sans contact dans un mouvement d'horlogerie. On réalise ou on transforme au moins un couple de composants antagonistes dudit mouvement d'horlogerie, dont l'un entraîne l'autre ou prend appui sur l'autre, par l'application d'un traitement superficiel ou dans la masse leur conférant une charge électrostatique ou/et magnétique de même polarisation ou/et aimantation au niveau de surfaces antagonistes, de façon à ce que lesdits composants antagonistes tendent à se repousser quand ils sont approchés l'un de l'autre. Ledit traitement consiste à créer ou déposer sur ladite surface de coopération ou/et sur ladite surface de coopération antagoniste au moins une couche mince. L'invention concerne encore un mécanisme d'horlogerie incorporant au moins un couple de composants antagonistes, dont l'un entraîne l'autre ou prend appui sur l'autre, ledit couple étant réalisé ou transformé par la mise en œuvre de ce procédé.
