    摘要： An electro-magnetic synchronous motor has an E-shaped stator linear or partially wrapped around an axis, the legs being the pole shoes. The middle leg includes a permanent magnet and one or both outer legs have coils. A movable displacement element has poles spaced further apart than the stator poles. The movable element has a stable position for zero energization in which one of its poles aligns with the stator pole having the permanent magnet. Coil energization disturbs magnetic field symmetry to move the element always in the right direction.

    摘要： In an elapsed-time meter, which comprises indicating digit wheels, which are mounted in a housing and operable by an electric motor via an interposed transmission, the rotor of the drive motor is rotatably mounted at one end in a partition contained in the housing and at the other end in a mounting plate, which on the side that is remote from the partition carries the transmission and which is integrally formed with resilient lugs, which cooperate with detent noses carried by the partition to detachably fix the mounting plate in position.

    摘要： A counting apparatus comprising a drum counting mechanism and a step motor for driving the drum counting mechanism. A housing for the drum counting mechanism includes a wall which forms a part of the housing for the step motor, the step motor including a rotor with a rotor shaft, which shaft extends through the wall. The step motor includes a stator coil which is supported on an extending portion of the housing for the step motor. Alternatively, a bearing and flange unit may be provided which extends through an opening in the common wall and which may have an extending portion on which the stator coil is mounted in surrounding relationship.

    摘要： The pulse counter device has a wheel with magnetic poles arranged regularly over its periphery. An element magnetisable by means of a coil is arranged to receive, at its terminals, signals representing pulses to be counted, these signals being adapted to take first and second values. The magnetisable element cooperates with the poles of the pole wheel so as to cause this wheel to rotate through a certain first angle, in a given direction, when the signal applied to the terminals of the coil passes from the first to the second value, means for rotating said wheel through a certain second angle, in the said given direction, when the signal at the terminals of the coil passes from the second to the first value. Registering means for the pulses to be counted, are driven by the pole wheel so as to indicate the advance by one unit when said wheel has rotated in the given direction. The means for rotating the wheel through the second predetermined angle comprises elastic return means adapted to cause said wheel to turn through the second predetermined angle, in said given direction, when the signal applied to terminals of said coil passes from the second to the first value, the second predetermined angle being substantially greater than the first. The elastic return means may be a polygonal cam turning against spring strips.
