The invention relates to a rotary electric machine with an eccentric rotor that comprises a stator and an eccentric rotor, the stator including a plurality of magnetic poles circumferentially distributed in order to define a closed cylindrical space, the rotor having a generally cylindrical shape with a diameter lower than that of said closed space and including a plurality of magnetic poles circumferentially distributed, the rotor rotating inside the closed space, wherein the machine further includes a shaft depending on the rotational component of the rotor, said machine being characterised in that, at the area of electromagnetic interaction between the stator and the rotor, the evolute of a stator pole and the evolute of a rotor pole have substantially equal lengths.
The invention relates to an assembly comprising a power transmitter (E) and a power receiver (R) respectively comprising a primary coil (11) and a secondary coil (22), in which the transmitter and the receiver are of the electromagnetic induction type and allow on the one hand the powering without electrical contact of the receiver by the transmitter, and on the other hand a bidirectional communication without electrical contact between the transmitter and the receiver.
A flexible energy transfer ribbon, comprising a magnetized strip (3) consisting of an elastomer material forming a matrix in which particles are embedded, communicating permanent magnetization oriented in the thickness direction of said strip thereto, at least one energy transfer member (2) extending along the support strip, and a coating material (1) in which the or each energy transfer member is embedded and adhering to the magnetized strip. It is noteworthy in that the magnetized strip is subdivided into successive sections (31) of lengths such that dimensional change effects induced in the magnetized strip especially through the effect of temperature differences induce, between the magnetized strip and the coating material, stresses that are low enough to prevent the adhesion between said magnetized strip and said coating material from weakening. Application in particular to optical links or low-current electrical links between means of equipment that can move relative to one another, especially rotating equipment.
A magnetic coupler with hysteresis (1) comprises an inductor subassembly (2) and an armature subassembly (6) that are capable of rotating one with respect to the other. The inductor subassembly has a plurality of magnetic poles and the armature subassembly (6) has one or more armature permanent magnets with hysteresis (11, 12). The invention is notable in that the or each armature magnet is produced in the form of a ring of one piece in magnetic material with vertical hysteresis and has through-slots for attenuating radial currents each running in the direction of the circumferential spread of the ring. Application to limiting heating and reducing axial bulk.
The invention relates to a device for thermoplastic material injection moulding. An injection longitudinal nozzle (13) arranged in the channel (15, 16, 17) of an injection matrix (1) is supplied by means of a distributor (18). The front end (74) of the nozzle (13) forwardly abuts against the collar (86) of the channel (15, 16, 17), whereas the rear end area (48) of the nozzle (13) is arranged in the longitudinal output channel (28) of a distributor (18) in such a way that it is longitudinally slidable therein and is mutually sealed therewith. Elastic means (100) presses the nozzle forwardly with respect to the distributor (18). Said invention is particularly suitable for slender nozzles.
The invention relates to a device for longitudinally injecting a thermoplastic material. The device is subdivided into two transversal subassemblies (45, 63) of which one comprises at least one injecting nozzle (21), a means (30) for supplying it with thermoplastic material, and a needle (122) for closing the nozzle (21), and the other comprises a motor means (123) for the closing needle (122). The closing needle (122) and the output element (155) of the motor means (123) are coupled by mutual joint means (129, 189) by relative displacement in a determined transversal direction, and the two subassemblies (45 and 63) are connected to one another in a fixed manner by correspondingly oriented mutual bayonet assembling means (78). The invention serves to simplify assembly and disassembly.
The invention relates to an injection moulding device. A heating sleeve (63) is arranged around the injection nozzle (19) with failsafe means (71, 109) that do not permit the above to reach an operating position in which electrical contact is established between the electrical conducting pads on said sleeve (63) and contact blades (107) connected to a controlled power supply except when in a given orientation. Of application to simplifying assembly and electrical connection.
The invention concerns a device for winding and unwinding an elongated flexible object. Said device (1) comprises a winding drum (8) mounted rotatable about an axis on a support (3) elastically returned upon rotation in the winding direction and forcefully connected, upon rotation, to a first part (60) of a sliding (60, 67) rotating coupling (67) whereof a second part (67) is connected to the support (3) through a freewheel device (23) enabling both parts (60, 67) to be jointly rotated in a direction corresponding to an unwinding action and immobilizing the second part (67) against rotation relative to the support (3) in a direction corresponding to a winding action to brake the winding. The invention is applicable to winders for electric cables, hoses and the like.
