Abstract: A magnetic card-shifting device for shifting a card, which has a ferromagnetic chip implanted in an edge thereof, from a first position, wherein the chip is spaced from the shifting device, to a second position displaced from the first position, the distance shifted being in excess of the initial displacement of the shifting device and implanted chip. The shifting device includes an electromagnet positionable adjacent the chip in spaced apart magnetic flux linking relationship therewith at an intermediate point between the first and second positions, and an electromagnet energization circuit for initially energizing the electromagnet with a first relatively high current level signal to exert a large attractive force on the implanted ferromagnetic chip and advance the chip into contact with the electromagnet, thereby simultaneously acquiring the card and advancing it to the intermediate position, and thereafter energizing the electromagnet with a second relatively low current level signal to exert on the ferromagnetic chip of the acquired card in contact with the electromagnet a relatively small force for holding the acquired card fixed relative to the electromagnet, thereby enabling movement of the acquired and fixedly held card from the intermediate position whereat the card is acquired to the second position in response to movement of the electromagnet from the intermediate position to the second position.

Abstract: An electromotive device including a stator provided with electromagnets, an eccentric armature mounted for movement by the electromagnets, and an output member which is concentric with the stator and is driven by the armature movement. A light-actuated electromagnet commutation system is disclosed. The armature of the electromotive device has epicyclic movement relative to both the stator and the output member with the two epicyclic movements cooperating to provide an integrated motor transmission unit.
